Straightly distributed solenoid valve

Abstract

The invention provides a direct-distributed solenoid valve, relating to a valve shell structure concerned with the initial sealing break or the final sealing, which is different from the turn-on or turn-off of the valve. The direct-distributed solenoid valve comprises a valve body (1), a screw-cap sealing washer (2), a screw-cap part (3), a pressure spring (4), a valve-core component (5), an electromagnetic head (6), a gasket (7) and a bolt (8), wherein, the screw-cap sealing washer (2) and the screw-cap part (3) are matted on the valve body (1) , and the valve-core component (5) props up the screw-cap part (3) by the pressure spring (4), with the other end sleeved outside the electromagnetic head (6). The direct-distributed solenoid valve utilizes the elasticity of the spring to help a gag bit replace when magnetic force disappears, with strong adaptability and an angle capable of being randomly selected. The screw-cap sealing washer coated with a ceramic layer is adopted, which greatly increases the sealing performance of the solenoid valve and is applicable to the transmission of various gases and fluids, including the transmission of corrosive fluids.

Description

technical field [0001] The invention relates to a valve casing structure related to the initial sealing movement or final sealing movement different from the opening or closing movement of the valve, in particular to a direct distributed solenoid valve. Background technique [0002] Solenoid valve is an automatic control element widely used in industrial production and daily life. The basic operating principle of the solenoid valve is to use the magnetic field generated or lost by the coil when the current is turned on or off to make the armature be attracted or released, thereby controlling the opening or closing of the delivery pipeline. However, in the current solenoid valve, when the coil is cut off and the electromagnetic field disappears, the armature completely relies on its own gravity to reset. This structure makes it necessary to ensure the verticality of the armature position during installation of the solenoid valve so as not to hinder its up and down freedom dur...

Problems solved by technology

However, in the current solenoid valve, when the coil is cut off and the electromagnetic field disappears, the armature completely relies on its own gravity to reset. This structure makes it necessary to ensure the verticality of the armature position during installation of the solenoid valve so as not to hinder its up and down freedom during pull-in and reset. This requirement limits the freedom of installation of the solenoid valve and makes the space where the pipeline is not compact enough

At the same time, as a component that controls the opening and closing of the pipeline for conveying fluid, the solenoid valve has relatively high requirements for internal sealing performance, especially when conveying high-temperature, high-pressure, and corrosive fluids. Relying on the tight fit between the metal surfaces processed into a high finish to play a sealing role, which not only increases the manufacturing cost, but also the metal is easy to wear and has a short service life
