What is a Lined Gate Valve
Lined Gate Valve Since the beginning of the 21st century, the world's petrochemical industry has gradually shifted to China. China has become the world's largest producer of petrochemical products. Crude oil processing capacity and ethylene production capacity now rank second and third in the wor ...
What is a pinch valve
Pinch valve is also called pinch valve, pressure pipe valve, casing valve, pinch valve, etc. in China. Use pneumatic, electric, manual or hydraulic driving methods to squeeze the casing to achieve the switch/adjustment. The casing (hose) is the most important part of the pinch valve. It provides cor ...
The role of the check valve
A check valve is a valve that automatically opens and closes the valve clack depending on the flow of the medium itself to prevent the medium from flowing back. The main functions of the check valve are: to prevent the medium from flowing backward, to prevent the pump and the drive motor from reve ...
Detailed introduction of knife gate valve
1. What is the function of the knife gate valve The gate has two sealing surfaces. The gate of the wedge knife gate valve can be placed as a whole, called a rigid gate; to improve its manufacturability, instead of the deviation of the angle of the sealing surface during the processing, this gate is ...
Rotary valve working principle and brief description.
The Rotary Disc Valve is commonly known as star feeder, rotary valve, fan shutoff, air lock, rotary feeder, etc. It is composed of a rotor with several blades, a shell, a seal, a motor, and a reducer. When the rotor rotates in the cylindrical casing, the materials falling from the upper hopper by it ...
The invention and wide application of ceramic regulating valve
The invention and wide application of Ceramic butterfly valve is an example. 1. The ceramic butterfly valve adopts high-tech new ceramic structural materials to make the sealing parts and vulnerable parts of the valve, which improves the wear resistance, corrosion resistance and sealing of the ...
The difference between PTFE and PFA
One. Different in nature 1. PFA: a copolymer of a small amount of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene. 2. PTFE: a polymer compound formed by polymerization of tetrafluoroethylene. Two, different characteristics 1. PFA characteristics: (1) Crystal material, low moist ...
Ceramic valve introduction
introduction Metal valves are commonly used in various industries in China. Metal valves have been used for hundreds of years. Although metal valves have undergone improvements in structure and materials, they are limited by the properties of metal materials and cannot adapt to increasing wear ...
The role and operation method of the inlet valve
effect： As an accident valve and an overhaul valve, the inlet valve usually has only two working states, fully open or fully closed, and cannot be used to adjust the flow. The main valve is not allowed to be opened in the case of moving water, its function is: (1) As a backup protection for the ov ...
Introduction of Knife Gate Valve
Knife gate valve is also called knife gate valve, knife gate valve, slurry valve, and mud valve. Its opening and closing part is a gate. The movement direction of the gate is perpendicular to the direction of the fluid. It is cut off by a blade-shaped gate that can cut fiber materials. Medium, t ...
What is a gate valve?
Working principle The opening and closing part of the gate valve is a gate. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate has two sealing surfaces. The tw ...
The working principle of butterfly valve
The working principle of butterfly valve The butterfly valve is a valve that opens and closes according to the rotation of the valve stem while driving the disc plate to rotate.In the cylindrical passage of the butterfly valve body, the disc-shaped butterfly plate rotates around the axis, mainly by ...
What are the good tastes of pinch valves?

Working principle of check valve
Check valve refers to a kind of valve whose opening and closing parts are circular flaps and rely on its own weight and medium pressure to block the backflow of medium. When the inlet pressure is greater than the weight of the flap and the flow resistance, the valve is opened. On the contrary, the v ...
ball valve product description
Ball valve, a valve whose opening/closing part (ball) is driven by the stem and rotates around the axis of the ball valve. It can also be used for fluid adjustment and control. Among them, the hard seal V-ball valve has a strong shear force between the V-ball core and the metal seat of the welded ...
Basic introduction of valve
The valve is a pipe accessory used to open and close the pipeline, control the flow direction, adjust and control the parameters (temperature, pressure and flow) of the transport medium. ...
