Product features and advantages of ball valve
Product features of ball valve: 1. The three-way ball valve adopts an integrated structure in structure, with a four-sided valve seat sealing type, fewer flange connections, high reliability, and a lightweight design. 2. The three-way ball core is divided into T type and L type, with long service life, large circulation capacity and low resistance. […]
Classification and characteristics of ball valve
There are different ways of classification of ball valves. Function classification: 1. Bypass valve: The ball valve is generally opened by static water, so the bypass valve is set to be pressed first, that is, both sides are filled with water; 2. Air valve: when filling with water, the buoy will automatically close the valve […]
Characteristics of ball valve
Features of ball valve: 1. Wear resistance; because the valve core of the hard-sealed ball valve is spray-welded alloy steel, The sealing ring is made of alloy steel surfacing, so the hard sealing ball valve will not produce too much wear when opening and closing. (Its hardness coefficient is 65-70): Second, the sealing performance is […]
What is a ball valve?
A ball valve is a valve in which the opening and closing parts (ball) are driven by the valve stem and rotate around the axis of the ball valve. It can also be used for fluid adjustment and control. Ball valves are divided into pneumatic ball valves, electric ball valves, and manual ball valves according […]
Knife gate valve introduction and its characteristics
Knife gate valve entered China in the 1980s. In less than two decades, its use has expanded from ordinary fields to a wider range of industries, from coal preparation, gangue discharge, and slag discharge in mines and power plants to Urban sewage treatment has evolved from general industrial pipelines to specialized pipeline systems for food, […]
Gate valve characteristics and installation notes
Gate valve characteristics: Light weight The body is made of high-grade nodular cast iron, the weight is about 20%~30% less than the weight of traditional gate valve, and the installation and maintenance are convenient. Flat bottom brake seat: Traditional gate valves often silt in the grooves at the bottom of the valve due to foreign […]
Classification and advantages of gate valve
Gate valve types: There are many domestic manufacturers of gate valves, and most of the connection dimensions are not uniform. Mainly divided into the following categories: 1. According to JB/T2203-1999 “Structural Length of Gate Valve”, the standard valve of the Ministry of Machinery; 2. According to GB/T12221-2005 “Metal Valve Structure Length”, the national standard valve; […]
Working principle and movement mode of gate valve
The gate valve is a gate for opening and closing. 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 through the contact between the valve seat and the […]
The difference between globe valve and check valve
With the development of high-tech industry, various valves are often used in daily life. Today we will understand the difference between globe valves and check valves. The difference between globe valve and check valve: 1. Check valve and stop valve are not the same thing, the difference between the two is mainly that the structure […]
Electric globe valves’ structural features and installation attention
Structural features of electric globe valve: 1. Open and close without friction. This function completely solves the problem of traditional valves affecting the sealing due to mutual friction between the sealing surfaces. 2. Top-mounted structure. The valves installed on the pipeline can be directly inspected and repaired online, which can effectively reduce device shutdown and […]
