Stop 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, screw connection, and welding connection. The "three modernizations" of valves in our country once stipulated that the flow direction of shut-off valves should be from top to bottom, so there is directional installation....

1、 Filter principle Y-type filters are an indispensable filtering device in pipeline systems that transport fluid media. Y-type filters are usually installed at the inlet of pressure reducing valves, relief valves, shut-off valves (such as the inlet end of indoor heating pipelines) or other equipment to remove impurities in the medium and protect the normal use of valves and equipment. The Y-shape...

A globe valve is a type of valve with a simple structure, small volume, light weight, low material consumption, and multiple optional properties. The reasons why it is widely accepted and applied are as follows: Function of shut-off valve 1. It is mainly used for cutting off and throttling in pipeline systems or production equipment. Due to the lower friction between the sealing surfaces of this t...

A gate valve is an opening and closing component, the direction of movement of which is perpendicular to the direction of the fluid. The gate valve can only be fully open and fully closed, and cannot be adjusted or throttled. Rising stem valve Rotate the handwheel to lift or lower the valve plate connected to the valve stem through the threads of the handwheel and the valve stem, achieving the fun...
