Abstract
The invention relates to an electromagnetic leading switch valve, belonging to the electromagnetic control leading switch valve, which can be used in discharge system. It has better sealing property, high working pressure, long service life and easy connection with the electric control system. The invention comprises a valve body, a upper cover plate, a pressure guide pipe, a valve block, a electromagnetic valve, a flexible valve plate and a spring. Wherein, the flexible valve plate is mounted between the upper cover plate and the valve body; both the two ends of entrance of valve body have pressure guide holes which are connected to relative holes of valve block via the pressure guide pipe and connected to the P, T, O interfaces of said electromagnetic valve; the electromagnetic valve is mounted on the valve block; and the electromagnetic valve, the valve block and the upper cover plate are integrated as a whole via the bolts.
Description
Technical field
The present invention relates to a kind of Electromagnetic Control guide's on-off valve.
Background technique
Traditional on-off valve is a flashboard valve, drives rigidity valve plate control valve switch with lead screw transmission.Handle with sleeve makes valve open; Counter-rotation is closed it.Adopt the feed screw nut transmission efficiency low, resistance is big in the operation, the operation effort, and it is big to wear and tear, and the life-span is short, and sealing is poor, and by the sealing of wedge shape flashboard, the joint steel contacts with steel, and flashboard weares and teares and gets rusty and all can destroy sealability.Improve working pressure, technological requirement is higher; The leading screw long term exposure gets rusty easily in a humid environment, makes operation difficulty more, and life of valve reduces.Also have a kind of self-service on-off valve, utilize the break-make of system start-up and the pressure medium control valve of setting up in service; Connect control loop with the rotation cone valve.This valve has overcome many shortcomings of lead screw transmission, and little as volume, operational torque is little, but poor sealing performance, working pressure is restricted, and pressure rating generally is no more than 1.6MPa, can not use in high-lift supply and drain water system.
Summary of the invention
The object of the invention overcomes above-mentioned the deficiencies in the prior art exactly, and a kind of good airproof performance, working pressure height, long service life are provided, the convenient electromagnetic pilot type switching valve that is connected with automatical control system.
The present invention includes valve body, upper cover plate, PRESSURE PIPE, valve piece, solenoid valve, flexible valve plate and spring; Flexible valve plate is installed between upper cover plate and the valve body, makes valve body top form independent pressure chamber, isolates with primary path; Valve body is imported and exported two ends and is equipped with pressure guide hole, pressure guide hole by on PRESSURE PIPE and the valve piece accordingly the hole connect, join with P, T, the O mouth of solenoid valve respectively again; Solenoid valve is installed on the valve piece, and solenoid valve, valve piece and upper cover plate are fixed together successively by bolt, and the joint adds corresponding Sealing.
For preventing that foreign material from entering pressure chamber, influence the valve proper functioning, filter also is installed on the PRESSURE PIPE that the pressure guide hole with the valve body entry end links to each other.Flexible valve plate employing can produce diastrophic rubber material and make.Solenoid valve adopts aqueous medium two-position three way open type ball valve, and solenoid valve is by changing the switching that different functional positions comes control valve.
The present invention forms pressure chamber between flexible flashboard and upper cover plate, control wherein variation in pressure by solenoid valve.Under the solenoid valve dead electricity situation, P mouth and A mouth are logical, and the pressure guide hole of valve body entry end is logical by PRESSURE PIPE, valve piece and solenoid valve P mouth, and A mouth and pressure chamber are logical, and valve body ingress high-pressure medium enters pressure chamber through solenoid valve.Flexible flashboard upside is subjected to making a concerted effort greater than the pressure medium of downside of pressure medium and spring force, and flexible flashboard is pressed on and makes valve closing in the outlet.Solenoid valve gets when electric, and the P mouth blocks, and A mouth and T mouth are logical, and the pressure chamber medium is discharged to outlet, and side pressure is moved on the flexible flashboard greater than upside under the flexible flashboard, imports and exports and connects.Valve has the automatic braking ability.The solenoid valve dead electricity, valve closing; Electromagnetism gets electric, then opens.
The present invention is applicable in the supply and drain water system.The present invention adopts flexible flashboard pressure controling mode, realizes valve opening and close that by the pilot pressure transmission mechanical friction is little, good airproof performance, long service life.Adopt solenoid valve as pilot valve, withstand voltage raising, applied widely in high-lift system, conveniently be connected with automatic control system, can in centralized control system, use.
