Common Problems of Forged Steel Valves1

Forged steel valves are mainly suitable for all kinds of fire power station on the pipeline, it can be used to control the flow of various types of fluids such as air, water, steam, corrosive media, mud, oil, liquid metal and radioactive media. 

Forged steel valves and other valve products compared to the characteristics of high temperature and pressure, unique self-sealing design, the higher the pressure, the more reliable sealing. Due to the performance of technical characteristics, the special conditions of the product also formed a substitute for other products can not be the characteristics.

Forged steel valves should pay attention to the valve body discharge and silk plug pressure problem. Valve pressure test, the sealed chamber cavity gas and moisture due to rising ambient temperature and pressure, grease when the first discharge pressure relief, in order to facilitate the smooth operation of the grease. After the grease, the air and moisture in the sealed chamber are fully displaced. Timely release valve chamber pressure, but also to protect the use of the valve safety. After the end of the grease, be sure to tighten the sewage and pressure plug plug to prevent accidents. When filling grease, pay attention to the problem of fat evenly. Normal injection of fat, from the mouth of the mouth of the mouth of the fat out of the first fat, and then to the low, and finally high, successive fat. If you do not press the law or not fat, to prove the existence of clogging, timely clearance.

Vertical Check Valve for Sale

Due to the pressure of the inlet end medium in the pipeline, the valve is opened or closed against the spring resistance. When the inlet end of the medium pressure is lower than the outlet side, the spring will be pushed to the valve seat valve to close the valve to prevent the media countercurrent, so play a stop effect. Vertical check valve is widely used in chemical, liquefied petroleum gas, fluid and other industries. Check vales can be divided into lift check valve, swivel check valve and butterfly check valve according to structure.

A vertical check valve is a device for use in industrial pipelines to prevent countercurrent flow. Valve ends must be blocked at both ends, should be stored in the dry and ventilated room. 

We can produce and sale all kinds of check valves, including vertical check valve, swing check valve, ball check valve and others.

 

Installation of Cast Iron Strainer

Cast iron strainer is widely used in metallurgy, chemical, petroleum, paper, medicine, food, mining, electricity, city, home and other gas fields. Cast iron strainer is an indispensable device for conveying media piping, is usually installed at the inlet end of a relief valve, locating valve or other device, to eliminate impurities in the media, protect the normal use of valves and equipment to reduce equipment maintenance costs.

The cast iron strainer must be installed according to the direction of the gas flow; Cast iron filter is made of washable synthetic material, installation should pay attention to the lid can be easily opened for cleaning and inspection; Cast iron strainer can be installed in the horizontal and vertical pipes, do not install the filter on the basis of instability.

How to Maintain The Valve?

There are many types of valves, including ball valve, globe valve, gate valve and others, in fact, all kinds of valves have their own unique maintenance methods, this article outlined to explain the maintenance of the valve.

The maintenance of the valve should start from its installation to its use and storage. When we install the valve, must carefully check the sign of the valve, installation path, to eliminate defects caused by the transport process, and eliminate the valves of the dirt. The installation can be connected directly by the valve device in piping. Under normal circumstances, can be installed anywhere in the pipeline.

During the use of the valve, we should keep the valves clean, drive screw must be lubricated regularly, once found fault, should immediately stop, and excluded malfunction.

When storing the valve, we should be regularly check the store place, valves should neatly stored in the room ventilated, dry place.
