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

In the magnetic control valve disclosed in the present invention, the intake valve core frame, the check valve core frame, and the exhaust valve core frame are respectively connected with the intake valve core magnetic ring, the check valve core magnetic ring and the exhaust valve core magnetic ring. The valve core magnetic ring, the intake valve magnetic gasket, the check valve magnetic gasket and the exhaust valve magnetic gasket form a valve core group with an integrated structure; It avoids the failure of spring elastic force, maintains the sealing effect, and improves the service life of the product; it uses a magnetic magnetic gasket to increase the sealing pressure, prevent air pressure leakage, and at the same time improve the low temperature resistance, and still has excellent sealing performance at extremely low temperatures.

Description

technical field [0001] The invention belongs to the technical field of valve bodies, in particular to a magnetic control valve. Background technique [0002] The sealing of the control valve in the prior art is mostly completely dependent on the pressure of the valve core spring. With the frequent compression of the valve core spring, the failure of the spring compression force is weakened, so that the valve core sealing pressure is reduced, thereby causing the pressure gas to leak; in addition, the ambient temperature When the temperature is lowered (for example, below -20 °C), the hardness of the control valve gasket increases at low temperature, which further reduces the sealing effect, resulting in the leakage of pressure gas. SUMMARY OF THE INVENTION [0003] The invention provides a magnetic control valve, which aims to solve the problem that the sealing of the control valve in the prior art is completely dependent on the pressure of the valve core spring, resulting ...
