Problems solved by technology

[0003] The present invention provides a magnetic control valve, which aims to solve the problem that the seal of the control valve in the prior art is completely dependent on the pressure of the valve core spring, resulting in frequent compression of the valve core spring, the spring compression force is weakened, and the sealing pressure of the valve core is reduced. decrease, resulting in pressure gas leakage; in addition, when the ambient temperature decreases (such as below -20°C), the hardness of the control valve gasket increases at low temperature, further reducing the sealing effect, resulting in the problem of pressure gas leakage

Abstract

The invention discloses a magnetic control valve. An air inlet valve element framework, a check valve element framework and an exhaust valve element framework of the magnetic control valve form an integrated valve element set with an air inlet valve element magnetic ring, a check valve element magnetic ring, an exhaust valve element magnetic ring, an air inlet valve magnetic sealing gasket, a check valve magnetic sealing gasket and an exhaust valve magnetic sealing gasket, the magnetic control valve uses magnetic attraction and repulsive force, the problem of spring elasticity failure is avoided, the sealing effect is kept, the service life of the product is prolonged, the magnetic control valve uses the magnetic sealing gasket, sealing pressure is increased, air pressure leakage is prevented, meanwhile, the low temperature resistance is improved, and extremely good sealing performance is still achieved at the extremely low temperature.

Description

technical field [0001] The invention belongs to the technical field of valve bodies, and in particular relates to a magnetic force control valve. Background technique [0002] The sealing of the control valve in the prior art mostly depends entirely on the pressure of the spool spring. With the frequent compression of the spool spring, the spring compression force becomes weaker, which reduces the sealing pressure of the spool, resulting in the leakage of pressure gas; in addition, the ambient temperature When the temperature is lowered (such as below -20°C), the hardness of the control valve gasket will increase at low temperature, which will further reduce the sealing effect, resulting in the leakage of pressure gas. Contents of the invention [0003] The present invention provides a magnetic control valve, which aims to solve the problem that the seal of the control valve in the prior art is completely dependent on the pressure of the valve core spring, resulting in fre...
