Hard sealed wafer butterfly valve
Ball valve and plug valve belong to the same type of valve, with only its closing part being a sphere. The sphere rotates around the centerline of the valve body to achieve opening and closing. Ball valves are mainly used in pipelines to cut off, distribute, and change the flow direction of the medium. Ball valve is a new type of valve widely used in recent years, which has the following advantage...
Globe valve, also known as shut-off valve, belongs to the forced sealing type valve and is a type of shut-off valve. There are three types of connection methods: flange connection, threaded connection, and welded connection. The "Three Modernizations" of valves in our country once stipulated that the flow direction of globe valves should be from top to bottom, so there is directionality during ins...
The installation of safety valves and the key points of pipeline layout design 1. The safety valve should be installed upright and close to the protected equipment or pipeline. If the arrangement cannot be approached, the total pressure drop of the pipeline from the protected equipment or pipeline to the inlet of the safety valve should not exceed 3% of the fixed pressure value of the safety valve...
How to use a pressure regulating valve to reduce delay in the analysis system? The process measurement is real-time, but the analyzer response cannot be real-time. From sampling port to analysis There is always a delay in the instrument. Unfortunately, this delay is often underestimated or misunderstood. In the analysis sampling system, delay is defined as the time required for a new sample to tra...
1、 What is the principle of a shut-off valve? A globe valve uses the torque of the valve stem to exert downward pressure on the sealing surface, relying on the pressure of the valve stem to tightly fit the sealing surface of the valve disc and the sealing surface of the valve seat, preventing the flow of medium or regulating the flow rate of medium. 2、 What is the scope of application of globe val...
Valves are important components in the pipeline system of petrochemical plants, with a wide variety and large quantity, and are one of the main sources of leakage in the plant. Therefore, the requirements for valve leakage are crucial. The sealing performance of a valve refers to the ability of each sealing part of the valve to prevent medium leakage. The main sealing parts of a valve include the ...
Electromagnetic valves are automation basic components used to control fluids and belong to actuators; Not limited to hydraulic, pneumatic. Electromagnetic valves are used to control the direction of hydraulic flow, and mechanical devices in factories are generally controlled by hydraulic steel, so electromagnetic valves are used. The working principle of an electromagnetic valve is that there is ...

Ball valve is a common type of valve, and its design characteristics make it widely used in various industrial applications. Ball valves are favored for their simplicity, reliability, and ease of operation, playing an important role in fluid control. The main components of a ball valve include a sphere with a diameter and inlet and outlet pipes located on both sides of the sphere. Spheres are usua...
