The butterfly plate of the soft seal butterfly valve is installed in the diameter direction of the pipe. In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When the rotation is 90°, the valve is fully opened.

The characteristics of the new high-life 20K butterfly valve and the use of the butterfly valve in the use process are generally horizontal. Soft seal butterfly valve can be divided into flange type soft seal butterfly valve,wafer and lug type butterfly valve and welded soft seal butterfly valve according to the connection mode.
20K Butterfly Valve

 1. The butterfly valve adopts three eccentric sealing structure, the valve seat and the butterfly plate almost no wear, with more and more tight sealing function.

2. The seal ring is made of stainless steel. It has the dual advantages of metal hard seal and elastic seal. It has excellent sealing performance under low temperature and high temperature conditions, and has the characteristics of corrosion resistance and long service life.
3. The plate sealing surface using surfacing cobalt-based carbide, sealing surface wear resistance, long service life.
4. The large size butterfly board adopts truss structure, high strength, large flow area, and small flow resistance.
5. The valve has a two-way sealing function, the installation is not limited by the flow of the media, but also by the location of space, can be installed in any direction.
6. The drive device can be multi-station (rotated 90 ° or 180 °) installation, user-friendly. Flanged center line butterfly valve is a nice one.

A plug body with a through hole is used as a valve for an opening/closing member of a plunger valve in China Famous Valves. The plug body rotates with the valve stem to open and close.

The plug body of the plunger valve is mostly a cone body (also has a cylinder body), and the conical hole surface of the valve body cooperates with a seal pair. The plunger valve is the earliest type of valve, with a simple structure, rapid switching, and low fluid resistance.
The ordinary plunger valve is sealed by the direct contact between the finished metal plug body and the valve body, so the sealing performance is poor, the opening and closing force is large, and it is easy to wear. Usually it can only be used for low pressure (not higher than 1 MPa) and small Caliber (less than 100 mm) occasions.

 When something goes wrong, butterfly valve must be repaired in time. Repairs of cast iron butterfly valve you wholesale should pay attention to the following points:

1. When the butterfly valve hydraulic drive equipment is faulty, repair personnel should be found to find the problem in time and repair it.
2. When the parts in the equipment are replaced, the oil in the accumulator should be brought out first to avoid the onset of the incident.
3. When replacing the electrical parts, the power should be closed in time to avoid the occurrence of electric shock.
4. When repairing, check whether the strength and hardness of the screws are up to the rules of the manufacturer.

The protection of butterfly valve hydraulic drive equipment is essential for everyday life. The main aspects of repair are:

1. After the butterfly valve hydraulic equipment is completed, add certain oil to the equipment according to the instructions. The new oil is filtered before it can participate in the fuel tank. So does the 10K swing wafer butterfly valve.
2, when it is the initial operation, admit the direction of the motor is not accurate.
3, after the initial operation, the pressure in the accumulator should use nitrogen, must not use oxygen, because it is so easy to attack explosion.
4, we should always check the machine's various parts if it is normal and damaged, if it is not normal, replace in a timely manner to avoid the incident.
5, there is a fault indication, oil spills and other abnormal phenomena, we must promptly review, if you found problems, timely repairs.

Stop Valve

Stop Valve

angle stop valve description

Stop Valve is mainly used to cut off or connect the pipeline, so that the system can operate normally. Therefore, it must be kept fully open or fully closed during use, and it is not allowed to be half open. Products are mainly divided into straight through stop valve and DOFUN angle stop valve.Applicable medium: R12, R22, R502, R134a, R404A, r507, R717, etc

ShanDong DoFun Refrigeration Technology Co., Ltd. ( Hereinafter referred to as DOFUN) is located in LiaoCheng, an ancient canal capital with rich historical and cultural heritage as well as beautiful scenery.

The true connotation of DOFUN is not only realizing the dream in the heart but also working at every products with great care to make it a metal art work. It will be the goal for us to fight for !

Stop valve, also known as the shut-off valve, is one of the most widely used valves. The reason why it is so popular is that the friction between the sealing surfaces during opening and closing is small, more durable, the opening height is not large, and the manufacturing is easy. Easy maintenance, not only suitable for medium and low pressure but also suitable for high pressure. The shut-off valve is a force-sealed valve, so when the valve is closed, pressure must be applied to the clapper to force the sealing surface to not leak.

The working principle of the stop valve: The valve plays an important role in cutting off and throttling the medium in the pipeline. As a very important shut-off valve, the stop valve is sealed by applying torque to the valve stem. The pressure is applied to the valve flap in the axial direction so that the sealing surface of the valve flap and the sealing surface of the valve seat closely fit together to prevent the medium from leaking along the gap between the sealing surfaces.

Stop Valve

The sealing of the stop valve is composed of the valve disc sealing surface and the valve seat sealing surface, and the valve stem drives the valve disc to move vertically along the centerline of the valve seat. During the opening and closing process of the stop valve, the opening height is small, easy to adjust the flow, and easy to manufacture and maintain, with a wide range of pressure application.

Compared with another gate valve, one of the commonly used shut-off valves in industrial production, from the structural point of view, the stop valve is simpler than the former, which is convenient for manufacturing and maintenance. In terms of service life, the sealing surface of the stop valve is not easy to be worn and scratched. During the opening and closing of the valve, there is no relative sliding between the valve flap and the sealing surface of the seat. The service life shut-off valve of the auxiliary valve has a small flap stroke in the fully closed process, and its height is smaller than other valves. The disadvantage of the stop valve is that the opening and closing torque are large and it is difficult to achieve rapid opening and closing. Because the flow path in the valve body is relatively tortuous, the fluid flow resistance is large, resulting in a large loss of fluid power in the pipeline.

The above information is provided by the shut-off valve factory.
