The air compressor safety valve has two categories: spring type and rod type.In addition, there are rushing safety valves, pilot safety valves, safety switching valves, safety decomposition valves, and static weight safety valves.Spring -type safety valve mainly relies on the force of the spring. It is closed and non -closed in the spring -type safety valve. Generally, flammable, explosive or toxic media should be closed. Steam or inert gases can be used.The formula, there are wrenches and no wounds in the spring -type safety valve.

Safety valve injection of air compressor
Causes and treatment methods of air compressor safety valve injection: 1. The excessive discharge capacity of the safety valve is not corresponding to the container equipment; 2. The section of the discharge pipe and the radius of its curvedNo right; reason 1 treatment method: the safety valve should be selected again.Reason 2 Treatment method: The safety valve should be replaced, or the import tube road should be adjusted again; reasons 3 Treatment method: re -adjust the gap between the regulatory ring and the valve flap.The screw air compressor safety valve is recommended to be repaired by the air compressor maintenance personnel, which can ensure the safety of the customer, but also ensure that the safety valve of the screw air compressor is not misunderstood.
Air compressor safety valve verification
There are five types of safety valves that require verification. The first is when the first use of the safety valve or when the price time is too long, and the second is the regular verification of the safety valve.The safety valve was severely corroded and damaged. The fourth was that the valve nameplate of the safety valve was lost, and the fifth was that the lead seal of the safety valve was damaged.The verification principle of the safety valve is to pass the verification medium under the pressure of 20MPa or above to the import of the safety valve that accepts the verification. When the pressure of the medium rises to a certain degree, the valve of the safety valve will be opened.At this time, record the pressure value at this time. Then, turn on the throne and adjust the pressure to the prescribed opening value. In this way, the verification of the pressure is completed, and then when the pressure drops to 90%of the opening pressure, use it, use it, use it, use it, use it, use it, use it, and use it.Observe the pressure gauge and other methods to check whether the safety valve is leaked. This item is a sealing verification of the safety valve.
Air compressor safety valve model
Generally, the models used by the air compressor safety valve are A28X-16T, copper, and there are AQ20 and AQ25 with stainless steel.Import safety valve preferred Italian OR brand.There are four main types of OR security valve models.1831 series (adjustable, temperature -resistant 180 ° C); 0485 series (spring micro -enable formula, temperature resistance 115 ° C); 0480 series (spring micro -enable type, temperature resistance 160 ° C) and 0490 series.
