What are the precautions for the flow direction of the three-way ball valve?
The three-way ball valve is mainly used to block, distribute and change the flow direction of the medium in the pipeline. There are two types of three-way ball valves: T-type and L-type. The T-shape can interconnect three orthogonal pipes and block the third channel. … -
The difference between rising stem gate valve and non rising stem gate valve
The gate valve is an opening and closing 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 valve is sealed by the contact between the valve seat and the gate plate. Usually, the sealing surface will be surfacing with metal materials to increase wear resista… -
Pneumatic ball valve structure and working principle
Pneumatic ball valves are widely used in petroleum, chemical plants, power generation, paper industry, nuclear energy, airlines, rockets and other units, and their daily life. Pneumatic ball valve is a kind of gate valve with pneumatic electric actuator, and the pneumatic electric actuator has a relatively fast speed and a faster switching speed, which is 0.05 seconds/time, so it is generally call… -
Detailed diagram of the structure of the triple eccentric butterfly valve
Traditional butterfly valve products have some disadvantages, such as not being able to be used in high temperature and high pressure environments, and poor sealing performance. The triple eccentric butterfly valve means that three eccentricities are made on the structure of the butterfly valve. This design process makes the triple eccentric butterfly valve make up for the shortcomings of the trad… -
What is the difference between high platform ball valve and ordinary ball valve
The high platform ball valve is an evolutionary product of the ordinary ball valve. It has all the functions of the ordinary ball valve, and it is more beautiful and delicate in shape than the ordinary ball valve.… -
The working principle of Swing check valve
What are the three types of swing check valves? A valve that opens and closes with the force of the medium flow to prevent the backflow of the medium is called a check valve. Check valves belong to the category of automatic valves. Mainly used in pipelines where the medium flows in one direction, allowing the medium to flow in only one direction to prevent accidents.… -
Common problems of regulating valve selection
As one of the indispensable equipment in industrial production, valves may encounter many problems from selection to use to maintenance.… -
The difference between rubber lined butterfly valve and rubber butterfly valve
The difference between rubber lined butterfly valve and rubber butterfly valve, the difference between rubber lined butterfly valve and plastic lined butterfly valve The rubber lining in rubber lined butterfly valve is to use high temperature to vulcanize rubber and valve body at high temperature, which has very high corrosion resistance. It is used to control some corrosive fluids with strong aci…
