Hard sealed wafer butterfly valve
Knife gate valves are used to cut off a variety of applications containing solid media, including oil sands slurry, pulp raw materials, mines, wastewater treatment and power stations and so on. In order to ensure normal use of routine maintenance and repair is also very important. 1. Adjust the packing once a month. 2. Lubricate the valve stem and stem nut every three months. This should be done w...
Globe valve, also known as cut-off valve, belongs to the forced sealing type valve, so when the valve is closed, pressure must be applied to the valve flap to force the sealing surface not to leak. It is one of the most widely used valves, it is popular because of the opening and closing process between the sealing surface of the friction is small, more durable, open height is not large, easy to m...
A globe valve is a type of valve that uses the valve disc to move along the center of the valve seat channel to control the opening and closing of the pipeline. The working principle of a shut-off valve is to change the flow area of the pipeline through the rotation or lifting movement of the valve disc, thereby controlling the flow rate and pressure of the medium. When the valve disc is closed, i...
Stop valve, Globe valve, also known as shut-off valve, is a forced sealing valve. Therefore, when the valve is closed, pressure must be applied to the valve disc to force the sealing surface to not leak. It is one of the most widely used valves, and its popularity is due to the low friction between the sealing surfaces during the opening and closing process, its durability, small opening height, e...
Basic structure of valve 01 Firstly, let's understand the basic structure of the valve. Valves are usually composed of valve bodies, valve covers, valve cores (or discs), seals, and operating mechanisms. The valve body is the main body of a valve, used to accommodate the valve core and seals. The valve cover is used to fix the valve core and seal. The valve core is the core of a valve, which contr...
Valve assembly is the final stage of the manufacturing process. Valve assembly is the process of combining the various components and parts of a valve according to the prescribed technical requirements, making it a part of the product The whole machine is the most basic unit for valve assembly, and several parts make up the components of the valve (such as valve cover, valve disc components, etc.)...
Valves are control components in fluid conveying systems, mainly used for opening and closing pipelines, controlling flow direction, adjusting and controlling parameters of the conveying medium (such as temperature, pressure, and flow rate). This article mainly introduces 8 common valves (ball valve, plug valve, butterfly valve, gate valve, globe valve, needle valve, solenoid valve, angle seat val...

01. Basic structure of gate valve Gate valve is a type of valve that cuts off slurry by lifting the gate. It has the advantages of simple structure, wear resistance, good sealing, and easy operation. Its basic structure includes valve body, gate plate, packing, movable bearings, and manual device, etc. 02. Why does the gate valve need to return half a turn 1. The closing and opening of the gate va...
