Sliding spool valve is the instead of rubber diaphragm, switching element as the sentinel valve opening and closing, elastomer diaphragm is to deflect the opening and closing that distortion realizes valve under the differential pressure action of front and back air chamber, and sliding spool valve is to move forward and backward the open and close that realize valve under the differential pressure action of front and back air chamber.Sliding spool valve is a kind of electromagnet sentinel valve, has that the amplitude of moving forward and backward is big, heatproof, corrosion-resistant, long service life, compact structure, a advantage that volume is little.As shown in Figure 1: pressurized gas enters preceding air chamber 1 and enters rear gas chamber 2 through throttle orifice 3 from the inlet opening of electromagnetic impulse valve, air chamber 1 and rear gas chamber 2 before sliding spool valve 10 is divided into air cavity, make former and later two air chambers keep separately pressure, electromagnetic pilot head 7 does not have the electrical signal input at this moment, vent hole 6 is by shutoff, the effect that the pressure of rear gas chamber 2 adds upper spring 8 moves forward sliding spool valve 10, and the delivery outlet of shutoff valve body 4 makes electromagnetic impulse valve be in closed condition.As shown in Figure 2, electrical signal input electromagnetic pilot head 7, vent hole 6 is opened, the pressure of rear gas chamber 2 is released, before the pressure of air chamber 1 move after forcing sliding spool valve 10, the delivery outlet of valve body 4 is opened pressurized gas from the delivery outlet winding-up of valve, electromagnetic impulse valve is in opening state.
This shows that variation moves forward and backward sliding spool valve 10 according to front and back air chamber pressure reduction, realizes the opening and closing of electromagnetic impulse valve.Sliding spool valve 10 should move forward and backward in air cavity, keep sealing again, air chamber pressure separately before and after keeping, but when the gap of sliding spool valve 10 and inner chamber (valve gap 5) change the back just may: 1) during gap smaller, sliding spool valve is stuck, and can not move forward and backward and loses the function of opening and closing; When 2) gap became big, sliding spool valve and air cavity lost seal action, and the front and back air chamber can not be kept independently pressure; Sliding spool valve can not normally move equally and lose switching function.
In order to enlarge the scope of electromagnetic impulse valve operating temperature, when becoming big or diminish, the gap of sliding spool valve 10 and valve gap 5 do not influence sliding spool valve moving in air cavity, can keep the sealing between former and later two air chambers again, therefore be necessary to improve existing electromagnetic impulse valve, design novel sliding spool valve and can adapt to the gap variation and proper functioning.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of electromagnetic impulse valve with self sealing sliding spool valve, make sliding spool valve can keep moving forward and backward and sealing two big functions, still can proper functioning under the bigger situation of temperature change scope, and simple in structure, use reliable.
