VALVE

  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 installation. The globe valve is designed with low inlet and high outlet to reduce flow resistance and save effort when opening the valve. When the valve is closed at the same time, the gasket between the valve shell and valve cover, as well as the packing around the valve stem, are not subjected to force and will not be affected by medium pressure and temperature for a long time. This can prolong the service life and reduce the probability of leakage. In addition, this can also replace or add packing when the valve is closed, making maintenance easier. In general, globe valves are l...

  Globe valves   are used to cut off the flow of media, and are suitable for situations that require frequent opening. The sealing parts of a globe valve are the valve disc and valve seat. In order to ensure a tight closing of the globe valve, the mating surface of the valve disc and valve seat should be ground or a gasket should be used. The sealing surface can also be embedded with corrosion-resistant and wear-resistant materials such as bronze and stainless steel.The valve disc and valve stem of the globe valve are connected in a movable manner to ensure a tight fit between the valve disc and valve stem. The lifting and lowering of the valve disc of a globe valve is generally controlled by the valve stem. The upper part of the valve stem is a handwheel, and the middle part is a threaded and packing sealing section. The function of the packing is to prevent the internal medium of the valve body from leaking along the valve stem. The function of a shut-off valve 1、 The main f...

  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 type of valve compared to gate valves, it is suitable for pipelines or devices with large pressure fluctuations and drastic temperature and pressure changes (such as the connection of nitrogen flushing pipelines). 2. The shut-off valve belongs to the forced sealing type valve, so the handle must be forcefully pushed to the fully closed position when opening and closing. When the medium flows from bottom to top, the fluid is filtered by the through check valve and enters the inner chamber of the through stop valve When the liquid medium flows through the through check valve...
