High-voltage magnetic exchange valve

Abstract

The invention relates to a high-voltage magnetic exchange valve which comprises a valve body, wherein a control assembly is arranged at the top of the valve body, and a valve rod installation channel and a plurality of air holes communicating with the valve rod installation channel are formed in the valve body; a valve rod is arranged in the valve rod installation channel, a plurality of valve heads are arranged on the peripheral surface of the valve rod, and sealing rings are arranged on the valve heads; a control channel communicating with the valve rod installation channel is formed in the middle of the control assembly, and a casing pipe is arranged in the control channel; a movable iron core and a static iron core are arranged on the back of the casing pipe, the movable iron core is connected with a magnetic coil, and the end part of the movable iron core is connected with the tail part of the valve rod; the inner part of each air hole is chamfered, a division plate is arranged at the junction of each air hole and the valve rod installation channel, and sieve meshes are formed in the division plate. The high-voltage magnetic exchange valve achieves the purpose of uniform air inflow and air outflow, and the movement stroke of the valve rod is short. Under the equivalent condition, the working times of the valve rod is 30% higher than that of the similar products.

Description

technical field [0001] The invention relates to the field of valves, in particular to a reversing valve of a high-pressure electromagnetic valve. Background technique [0002] Electromagnetic reversing valve refers to the electromagnetic valve used in various normal temperature, high temperature, negative pressure, low pressure, high pressure occasions, the applicable fluid is air, nitrogen, oxygen, hydrogen, helium, carbon dioxide gas, argon, methane and other gas pipelines ;Mainly used in medical equipment, rubber and plastic machinery, clothing equipment, drying equipment, pharmaceuticals, refrigeration, HVAC, electroplating coating, food and beverage and vacuum equipment and other industries. The current electromagnetic reversing valve has small flow and low frequency. The problem of short service life. For example, the solenoid valve with 2-position and 5-way of similar products has 7 seals rubbing against each other when it is working, so the efficiency is low and the ...

[0002] Electromagnetic reversing valve refers to the electromagnetic valve used in various normal temperature, high temperature, negative pressure, low pressure, high pressure occasions, the applicable fluid is air, nitrogen, oxygen, hydrogen, helium, carbon dioxide gas, argon, methane and other gas pipelines ;Mainly used in medical equipment, rubber and plastic machinery, clothing equipment, drying equipment, pharmaceuticals, refrigeration, HVAC, electroplating coating, food and beverage and vacuum equipment and other industries. The current electromagnetic reversing valve has small flow and low frequency. The problem of short service life. Take the 2-position 5-way solenoid valve of similar products as an example. When it is working, all 7 seals are rubbing, the efficiency is low, and the service life is short.
