The Components Of Stainless Steel Angle Seat Valves Must Be Treated Before Assembly

Valves are closely related to People's Daily life and can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media, and are also indispensable parts of various mechanical equipment such as internal combustion engines, steam engines, compressors, pumps, pneumatic transmission devices, hydraulic transmission devices, vehicles, ships and aircraft. Stainless steel Angle seat valves are widely used in petroleum, chemical, light industry, food, medicine, environmental protection and other industries to adjust the direction of the medium, flow, speed and other parameters in the industrial control system. Stainless steel Angle seat valve adopts air control, can be used in no electricity, flammable and explosive occasions, low starting pressure, low pressure can be used to control high pressure, link rod and other parts are made of stainless steel material, can be used for high temperature, strong corrosion and other liquids, the actuator part can be rotated 360°, easy to install.

The components of stainless steel Angle seat valves must be treated before assembly, including:

1, according to the processing requirements, some parts need to be polished, the surface can not have processing burrs.

2. All parts are degreased.

3, after degreasing is completed, pickling passivation, cleaning agent does not contain phosphorus.

4, after pickling and purification, rinse with pure water, no agent residue, carbon steel parts omit this step.

5, the parts are dried with non-woven fabric one by one, and the surface of the parts can not be retained by wire wool, or blown dry with clean nitrogen.

6. Wipe the parts one by one with non-woven cloth or precision filter paper soaked with analytical pure alcohol until there is no dirty color.

Stainless steel Angle seat valve adopts unique fixed piston sealing technology, combined with the body cavity design more in line with fluid engineering, suitable for short time and frequent start-up conditions, is a common pipeline switch in automatic control system, and is widely used in filling, printing and dyeing, bleaching, food, washing, chemical, water treatment, medicine and other automatic mechanical equipment. It has the characteristics of no water knock, no noise, reliable sealing performance and so on.

Single and double action of stainless steel Angle seat valve:

1, single action (pneumatic head is usually a hole); Working principle; According to the function of spring return to open and close, it is divided into normally open type and normally closed type.

2, double action (pneumatic head is usually two holes); Working principle: air supply controls its switch. (According to customer requirements, you can also choose double action and spring return.)

Stainless steel Angle seat valve is widely used in short time frequent start, with sensitive response, accurate action characteristics, with the use of solenoid valve, pneumatic control can accurately control the flow of gas and liquid.
