Groove gate valve is a mechanical product subject to internal pressure. It is necessary to have sufficient strength and stiffness to support long-term operation without splitting and deformation. When designing and manufacturing groov...
Groove gate valves are usually designed with single gate, double gate, wedge and parallel structure. Wedge double gate (Z42, Z62 series) and wedge elastic gate (Z40, Z60 series) are most widely used.
Fire valve is an important accessory for industrial and construction pipeline control. Fire valve is composed of body, opening and closing organization and valve cover.
There is a pressure relief hole connected inside the valve to solve the abnormal pressure in the middle chamber and balance the pressure in the middle chamber. Opening the pressure relief hole is the most economical and effective solu...
Gate valves can be divided into wedge type, single gate type, elastic gate type, double gate type and parallel gate type according to their internal structure. According to the difference of stem support, it can be divided into open s...
Many people don't know that if the pressure of cast steel gate valve exceeds a certain range in work, it will do great harm to cast steel gate valve. Today, Xiaobian will tell you about the danger of excessive pressure in cast steel g...
In the design of stainless steel gate valve, it is found that in addition to the strength of the valve body, the stiffness of the valve body should be considered in the design of the thickness of the valve body. That is to say, the de...
Balance valves are composed of one-way valves and sequential valves. Balance valves can be divided into three types: static balance valves, dynamic balance valves and pressure-independent balance valves.
