Marine valve exporter shares with you.

Leakage of valve body and bonnet

the reason:

1. The casting quality of the cast iron parts is not high, and there are defects such as sand holes, loose structure and slag inclusion on the valve body and valve cover body;

2. Freeze cracking;

3. Poor welding, there are defects such as slag inclusion, unwelded, stress cracks;

4. The cast iron valve is damaged after being hit by a heavy object.

Maintenance method:

1. Improve the casting quality, and perform the strength test in strict accordance with the regulations before installation;

2. For valves with air temperature below 0℃ and below 0℃, heat preservation or heat mixing shall be carried out, and the valves which are out of service shall exclude accumulated water;

3. The welding seam of the valve body and valve cover composed of welding shall be carried out in accordance with the relevant welding operation regulations, and the flaw detection and strength test shall be carried out after welding;

4. It is forbidden to push or release heavy objects on the valve, and it is not allowed to hit the cast iron and non-metallic valves with a hammer. The installation of large-diameter valves should have a bracket.

Leakage at the packing

The leakage of the valve is the largest in the packing.

the reason:

1. Wrong choice of filler, not resistant to the corrosion of the medium, not resistant to the use of high pressure or vacuum, high temperature or low temperature of the valve;

2. The packing is not installed properly, and there are defects such as small-to-large, bad spiral coiled joints, loose tightening, etc.;

3. The filler exceeds the service period, has aged, and has lost its elasticity

4. The precision of the valve stem is not high, and there are defects such as bending, corrosion and wear;

5. The number of packing circles is insufficient, and the gland is not pressed tightly;

6. The gland, bolts, and other parts are damaged, so that the gland cannot be compressed;

7. Improper operation, excessive force, etc.;

8. The gland is skewed, and the gap between the gland and the stem is too small or too large, causing the stem to wear out and the packing to be damaged.

Self Contained Check Valves

Maintenance method:

1. The material and type of filler should be selected according to the working conditions;

2. Install the packing correctly according to the relevant regulations, the packing should be placed and tightened circle by circle, and the joint should be 30℃ or 45℃;

3. Packing that is too long, aging or damaged should be replaced in time;

4. The valve stem should be straightened and repaired after bending and wear, and it should be replaced in time for serious damage;

5. The packing should be installed according to the specified number of turns, the gland should be tightened symmetrically and evenly, and the pressure sleeve should have a pre-tightening gap of more than 5mm;

6. The damaged gland, bolt and other parts should be repaired or replaced in time;

7. Observe the operating regulations, except for the impact handwheel, operate with normal speed and normal force;

8. The gland bolts should be tightened evenly and symmetrically. The gap between the gland and the stem is too small, and the gap should be increased appropriately; the gap between the gland and the stem is too large and should be replaced.

        Check valves are probably the most misunderstood valves in history. If you mention check valves to most factory personnel, the typical response is "they don't work." In fact, these people are likely to have removed internal components or reinstalled system piping to avoid check valves. The check valve allows one-way flow and automatically prevents back flow (reverse flow) when the fluid in the pipeline reverses flow. They are one of the few automatic valves that do not require auxiliary opening and closing. Unlike other valves, even if the power plant facility loses air, electricity, or someone who may manually circulate the valve, the valve can continue to work. Check valves are everywhere, including at home. If you have a sewage pump in the basement, there may be a check valve on the pump discharge line. Outside the home, they can be found in almost every industry where pumps are located. Like other valves, check valves can also be used for various media: liquids, air, other gases, steam, condensate, and in some cases, liquids with fine particles or mud. Applications include pump and compressor discharge, headers, vacuum circuit breakers, steam lines, condensation lines, chemical feed pumps, cooling towers, loading racks, nitrogen purge lines, boilers, HVAC systems, utilities, pressure pumps, sewage Pumps, flushing stations, and spray lines. Check Valves How they operate Check valves are sensitive to flow and rely on pipeline fluid to open and close. The internal flap allows fluid to flow forward, thereby opening the valve. The disc starts to close the valve because the forward flow decreases or reverses, depending on the design. The structure is usually very simple, with only a few parts, such as the valve body, valve seat, valve flap, and valve cover. Depending on the design, there may be other items such as valve stems, hinge pins, clapper arms, springs, balls, elastomers, and bearings. The internal sealing of the check valve disc and valve seat depends on the fluid back pressure, not the mechanical force used to open and close the valve. Therefore, the allowable valve seat leakage rate of the check valve is greater than that of the on-off valve. Metal sealing surfaces usually allow some leakage, while elastomers, such as nitrile rubber and fluoroelastomer, provide airtight closure (zero leakage). Therefore, elastomers should be considered for chemically compatible air/gas media and low-pressure seals. The above information is provided by the check valve supplier.

                  Many people buy jewelry like rainbow gemstone. For example, you want to buy sapphire, tourmaline, and amethyst. But one of the lessons learned in the trading of colored gemstones is that most customers are mainly interested in color, and less so much in the type of gemstone, as long as the stone they buy is durable enough for their purpose. That is not. When it comes to buying loose gemstones, color certainly is the most important factor for most people, so it makes sense to start your search by searching for gemstones by color.

                  Jewels are often difficult to find by color. This is because websites typically keep their inventory organized by gem type rather than color. Therefore, for those who want to know what the options are for a particular color, here is a list of gem types organized by color.

                  It's easiest to start with the basic colors, where people draw. Consider a rainbow of red, yellow, pink, green, orange, purple and blue. This is a color baseline (but don't forget black, brown, white; this completely covers the analogy of the rainbow, but there are other unique options). If you're looking for a jewelry colored gift, start with your favorite color. If it is a gift for friends and loved ones, focus on their color style.

                  It's a good idea to consider the color of the clothes your friends often wear. If she wears mostly black clothes, she has a million different colors to choose from, which makes it difficult to judge. If she wears a lot of prints, patterns, and textures, she needs something tighter or one that works with yarn. For example, animal print enthusiasts can love statement rings in brown, champagne and white diamonds.

                  The terms ammolite and ammonite are sometimes used interchangeably. However, strictly speaking, ammonites refer to the fossil shells of ammonites, whether or not they are of gem quality. Ammolites are gem-quality materials made from fossils of certain types of ammonites.

                  Ammonites were marine mollusks that were extinct about 65 million years ago. There are many types of ammonites and their fossils are found all over the world at online jewelry stores. The fossils of Placenticeras meeki, Placenticeras intercalare, and Baculites compressus are capable of producing gem-quality ammolites. To date, this material has only been found in Alberta, Canada.

                  There are other gem-quality ammonites, such as Lumachel, a pebbled cut from a fossil of Carnite Floridas found in Austria. This iridescent material resembles an amorite, but with a different mineral composition.
