As a  Flange Check Valve Manufacturer , share with you. Swing Check Valve   1. In order to prevent the medium from flowing backward, check valves should be installed on equipment, devices and pipelines; 2. The check valve is generally suitable for clean media, and should not be used for media containing solid particles and large viscosity; 3. Generally, horizontal lifting check valves should be used on horizontal pipes with a nominal diameter of 50mm; 4. straight-through lifting check valve can only be installed in horizontal pipelines; 5. For the inlet pipeline of the pump, a foot valve should be selected. The foot valve is generally only installed on the vertical pipe of the pump inlet, and the medium flows from bottom to top; 6. Lifting type has better sealing performance than swing-opening type, and has larger fluid resistance. It should be installed on horizontal pipelines horizontally and vertically on vertical pipelines. 7. The installation position o...

As a  Ball Check Valve Leading Supplier , share with you. 1.  Swing Check Valve : The disc of the swing check valve is disc-shaped and rotates around the rotation axis of the valve seat channel. Because the channel inside the valve is streamlined, the flow resistance is smaller than that of the lift check valve, which is suitable for Velocity and flow do not change in large diameter occasions, but it is not suitable for pulsating flow, and its sealing performance is not as good as the lifting type. Swing check valve is divided into three types: single, double and multiple. These three types are mainly divided by the valve diameter, in order to prevent the hydraulic shock when the medium stops flowing or flows backward. 2. Lift check valve: check valve with valve disc sliding along the vertical centerline of the valve body. Lift check valve can only be installed on horizontal pipelines. On high-pressure small-diameter check valves, the valve disc can be a ball. . The shape...

The opening and closing parts of the   Resilient Seat Gate Valve  are gates. The movement direction of the gates is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed, and cannot be adjusted and throttled. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used gate valves form a wedge shape. The wedge angle varies with the valve parameters, usually 50, and 2 ° 52 '' when the medium temperature is not high. The gate of the wedge gate valve can be made into a whole, called a rigid gate; it can also be made into a gate that can produce a small amount of deformation to improve its processability and make up for the deviation of the sealing surface angle during processing. The plate is called a spring gate. Resilient Seat Gate Valve Elastic seated gate valve is also called lift rod gate valve (also known as open rod gate valve). Usually, there is a trapezoidal thread on the lifting rod, and the rotary...

To share with you as a  Butterfly Valve Supplier . Butterfly valve is a valve that uses a disc-shaped opening and closing piece to revolve around 90 ° to open, close or adjust the medium flow. The butterfly valve is not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving torque, easy to operate, and fast, but also has good flow regulating function and closed sealing characteristics. It has been developed in recent decades. One of the fastest valve varieties.  Butterfly Valve  is very widely used. The variety and quantity of its use continue to expand, and it has developed to high temperature, high pressure, large caliber, high sealing, long life, excellent regulating characteristics, and multi-function of a valve. Its reliability and other performance indicators have reached a high level. Lug Type Butterfly Valve With the application of chemically resistant synthetic rubber to butterfly...
