Problems solved by technology

Since the pressure of the medium in the valve seat of the solenoid valve changes greatly during operation, it has a great influence on the suction force of the solenoid, so the usual solenoid valve can only work in one direction, that is, the function of the solenoid valve can only be realized when it is used in accordance with the specified medium flow direction. , usually used in pneumatic control, and cannot be used for water, gas and oil media

Embodiment Construction

[0014] The direct-acting two-position four-way solenoid valve adopts a pressure-balanced sealing structure and includes a valve body 1, four valve seats 5, 7, 9, 11, and a valve stem assembly 4. The valve body 1 is provided with four medium circulation channels 12, which connect the uppermost port 6 and the lowermost port 2 (see figure 2 ), its port 2 is the medium drain port. The valve body is provided with four valve seats 11, 7, 5, 9 corresponding to the four ports 2, 3, 6, 10, and a valve plug assembly 8 mounted on the valve stem by four valve plugs and four valves Seats 5, 7, 9, and 11 form a sealing surface to form a valve body-connected sealing structure. Port 6 and port 2 are connected through the medium passage 12, so that no matter which medium enters from port 3, 6, 10, the valve can be made The rod assembly 4 is a group of continuous transport systems that are not affected by the force of the medium, but are only affected by spring force, gravity and electromagnet...

Abstract

The invention discloses a directly-operated type two-position four-way solenoid valve with a pressure balanced sealing structure. The directly-operated type two-position four-way solenoid valve comprises a valve body, four valve seats and a valve rod assembly. The valve body is provided with four medium feeding/discharging ports, wherein the uppermost port is connected with the lowest port; the valve body is internally provided with the four valve seats corresponding with the four ports; valve plug sets forming the valve rod assembly can form a sealing surface together with the four valve seats, and thus, a valve body connected type sealing structure is formed; and after medium enters the valve body, the valve rod assembly can be balanced through bearing an upward pushing or downward pressing medium force so that the directly-operated type two-position four-way solenoid valve with the valve body connection pressure balanced sealing structure is formed. The directly-operated type two-position four-way solenoid valve can work under a vacuum condition. Working without pressure difference, boosting at one port or alternately boosting at more ports can be realized, and the reversing function of the directly-operated type two-position four-way solenoid valve is flexibly exerted. Directly-operated type control for solenoid valves with larger calibers can be realized within the relatively economic electromagnet range.

Description

Technical field [0001] The invention relates to a solenoid valve used in automatic control, in particular to a direct-acting two-position four-way solenoid valve. Background technique [0002] Solenoid valve is an executive element for self-operation control of piping system. It has two-position action of opening and closing. Generally, solenoid valve pushes the valve plug to reciprocate by transmitting pressure to realize valve closing or opening. Because the pressure of the medium in the valve seat of the solenoid valve varies greatly during operation, it has a great influence on the suction force of the solenoid, so the usual solenoid valve can only work in one direction, that is, the function of the solenoid valve can be realized when used in accordance with the specified medium flow direction. , Usually used in pneumatic control, can not realize the common use of water, gas and oil media. Summary of the invention [0003] The technical problem to be solved by the present inv...
