The advantages and shortcomings of flat gate valve
The advantages of flat gate valve The flow resistance is small, and its flow resistance without shrinking is similar to that of a short tube. The flat gate valve with diversion hole can be directly used for pigging when installed on the pipeline. Since the gate slides on the two valve seat surfa...Read more -
Features and Applicable occasions of flat gate valve
The flat gate valve is a sliding valve whose closing member is a parallel gate. The closing part can be a single gate or a double gate with a spreading mechanism in between. The pressing force of the gate to the valve seat is controlled by the medium pressure acting on the floating gate or the fl...Read more -
Knife gate valve performance and installation
Knife gate valve has the advantages of simple and compact structure, reasonable design, light material saving, reliable sealing, light and flexible operation, small size, smooth passage, small flow resistance, light weight, easy installation, easy disassembly, etc. It can work at a working press...Read more -
The difference between rising stem gate valves and non-rising stem gate valves
The difference between rising stem gate valves and non-rising stem gate valves Gate valve can be divided into: 1, rising stem gate valve: stem nut in the valve cover or bracket, open and close the gate, with rotary stem nut to achieve the rise and fall of the stem. This structure is advantageous...Read more -
What are the structural features of gate valves
Gate valve has the characteristics of small fluid resistance, applicable pressure, temperature range, etc., is one of the most commonly used cut-off valve, used to cut off or connect the medium in the pipeline. The diameter shrinkage can reduce the size of the parts, reduce the force required f...Read more -
Introduction of several types of gate valves
Introduction of several types of gate valves (1) Wedge type single gate valve The structure is simpler than the elastic gate valve; ② At high temperature, sealing performance is not as good as elastic gate valve or double gate valve; ③ Suitable for high temperature medium which is easy t...Read more -
Knife type gate valve performance and installation
Knife gate valve has the advantages of simple and compact structure, reasonable design, light material saving, reliable sealing, light and flexible operation, small volume, smooth channel, small flow resistance, light weight, easy installation, easy disassembly and so on. It can work normally und...Read more -
Structural characteristics and selection techniques of direct-flow globe valve, angle globe valve and plunger valve
Due to the low friction between the sealing surfaces during the opening and closing process, the shut-off valve is relatively durable and has a small opening height. It is not only suitable for medium and low pressure, but also suitable for high pressure media. Relying on the pressure of the v...Read more -
What are the several types of ball valves ?
As the most widely used valve, the ball valve is also the most type of valve. A variety of types meet the user’s application in different medium occasions, different temperature environments and different process requirements in the actual process. The following introduces the characteri...Read more -
The characteristics of Vertical check valve
Overcoming the spring resistance makes the valve open or close. When the medium pressure at the inlet end is lower than the inlet end, the vertical check valve: due to the pressure of the medium at the inlet end of the pipeline. The spring pushes the valve core to the valve seat to close the ...Read more -
Ball valve installation method
Several common valves used in industrial pipelines, ball valves are the most widely used, whether it is ordinary medium pipelines for water, oil and gas or harsh working conditions containing high-hardness particles, whether it is low temperature, high temperature, or corrosive environment, you ...Read more -
Development and Application of Metal Seal Butterfly Valve
The disadvantage of the rubber seal butterfly valve is that when it is used for throttling, cavitation will occur due to improper use, causing the rubber seat to peel off and damage. For this reason, metal-sealed butterfly valves have been developed internationally, and the cavitation zone has...Read more
