Summary of the invention
The purpose of this utility model overcomes deficiency of the prior art, provides that a kind of structure is simple, the pressure regulator valve of good sealing effect, spool long service life, is especially applicable to using in automobile dynamic system.
The technical solution of the utility model is: a kind of pressure regulator valve, comprise upper valve body and lower valve body, described upper valve body upper inside surface has been threaded adjusting nut, described upper valve body upper lateral is provided with positioning screw hole, described upper valve body bottom is connected with piston, Compress Spring is provided with between described piston and adjusting nut, described piston lower portion is cylindrical cavity space, upper valve core is had along its internal surface cover in described cylindrical cavity space, Returnning spring is provided with between described upper valve core and cylindrical cavity top of space, the first groove is provided with bottom described upper valve core, middle spool is provided with in described first groove, described middle spool bottom is provided with lower valve core, the described lower valve body position vertical direction corresponding with lower valve core is provided with import, the position vertical with lower valve core is provided with outlet, described import upper surface center is provided with the second groove, inner ring valve seat is provided with in described second groove, described second groove upper surface outward extending position annular array is provided with some projections, described projection is located at middle spool lower end, described import increases gradually to downward-extension internal diameter, on lower valve interior wall, filter screen is provided with below described import.
Further, the position of described positioning screw hole is between the fore-and-aft distance of adjusting nut.
Further, O RunddichtringO is provided with between described piston and upper valve body.
Further, described inner ring valve seat bore reduces gradually.
Further, described lower valve core is made up of some rubber pads, is connected between described some rubber pads by spring or bolt, and the shape of described some rubber pad compositions is corresponding with inner ring valve base inner wall shape.
Further, described import part is on the lower provided with annular boss, under described filter screen is located at annular boss, and is bolted.
Further, described projection is at least provided with 3.
Further, described projection is lower than inner ring valve seat supporting plane 0.005-0.015mm.
The advantage that the utility model has and good effect are: protruding is arranged so that lower valve core is not easily damaged by highly pressurised liquid, simultaneously three layers of spool be arranged so that sealing is tighter, moreover lower valve core becomes the trapezoidal of downward reduction, also make sealing effect better, and connected by spring between rubber pad, the damage of a rubber pad does not affect the use of pressure regulator valve entirety, increases the service life; There is structure simple, the advantages such as processing cost is low, long service life.

Embodiment
As Figure 1-3, the technical solution of the utility model is: a kind of pressure regulator valve, comprise upper valve body 1 and lower valve body 2, described upper valve body 1 upper inside surface has been threaded adjusting nut 3, described upper valve body 1 upper lateral is provided with positioning screw hole 4, the position of described positioning screw hole 4 is between the fore-and-aft distance of described adjusting nut 3, described upper valve body 1 bottom is connected with piston 5, O RunddichtringO 6 is provided with between described piston 5 and upper valve body 1, Compress Spring 7 is provided with between described piston 5 and adjusting nut 3, described piston 5 bottom is cylindrical cavity space, upper valve core 8 is had along its internal surface cover in described cylindrical cavity space, Returnning spring 9 is provided with between described upper valve core 8 and cylindrical cavity top of space, the first groove 10 is provided with bottom described upper valve core 1, middle spool 11 is provided with in described first groove 10, described middle spool 11 bottom is provided with lower valve core 12, described lower valve core 12 is made up of some rubber pads 13, connected by spring or bolt between described rubber pad 13, the described lower valve body 2 position vertical direction corresponding with lower valve core 12 is provided with import 14, the position vertical with lower valve core 12 is provided with outlet 15, described import 14 upper surface center is provided with the second groove 16, inner ring valve seat 17 is provided with in described second groove 16, and shape and inner ring valve 17 inner wall shape that described some rubber pads 13 form are corresponding, described inner ring valve seat 17 internal diameter reduces gradually, described second groove 16 upper surface outward extending position annular array is provided with at least 3 projections 18, described protruding 18 are located at middle spool 11 lower end, described protruding 18 lower than inner ring valve seat 17 supporting plane 0.005-0.015mm, described import 14 increases gradually to downward-extension internal diameter, on lower valve body 2 inwall, filter screen 19 is provided with below described import 14, described import 14 part is on the lower provided with annular boss 20, described filter screen 19 is located at annular boss 20 times, and be bolted, filter screen 19 can filter out the impurity in fluid, make impurity can not enter the inside cavity of valve, thus avoid impurity buildups in the inside cavity of valve, extend the working life of valve.
The working procedure of this example: when pressure is excessive, by liquid jack-up, thus there is gap in lower valve core 12, liquid flows out from outlet 15; When the pressure decreases, lower valve core 12 returns to original position downwards due to the effect of Returnning spring 9, in recovery process, lower valve core 12 can produce certain inclination, lower valve core 12 lower end surface first contacts with inner ring valve seat 17, liquid flows out from the gap formed between the side that lower valve core 12 tilts and protruding 18, and when pressure minimizes, lower valve core 12 returns to original position.
