Further, the top of the valve deck has the hexagonal threaded hole for conveniently tightening valve deck.
The utility model has the following beneficial effects: overcome the pressure of outer pressing spring to do work bottom spool when pressure is excessive, it will
Core assembly, which integrally jacks up, to be come, and liquid or gas are discharged from the overflow hole of valve body side, to realize overflow valve overflow
Effect；In overflow, when gas or liquid pass through cambered surface portion, flowing is gentler, prevents air pressure from rising suddenly and sharply and damaging overflow valve；
Reset when, there are overflow hole gases below or liquid can be smoothly discharged by ventilative through hole, avoid upper valve core because
Pressure is uneven and cannot smoothly reset, and improves the combination precision between sealing ring and valve body；If pressure reduces suddenly when resetting,
When outer pressing spring momentary reset, since sealing ring has certain buffer function, it can prevent between upper valve core and valve body acutely
Collision, in addition interior pressing spring can also offset the inertia that lower valve body moves down, and lower valve body is prevented to be detached from upper valve due to effect of inertia
Body, and movement is gentler when reset, and the combination between upper valve body is very accurate always, and sealing effect is more preferable.

Specific embodiment
The utility model is further described below in conjunction with attached drawing:
As shown in Figures 1 to 4, a kind of hardware flow spill valve, including valve body 1, valve deck 2 and core assembly, the valve deck 2 cover
It is located at the top of valve body 1, the core assembly is arranged inside valve body 1, has the overflow hole around week setting on the side wall of valve body 1
11, the core assembly includes upper valve core 3, bottom spool 4, outer pressing spring 5, interior pressing spring 6, circlip 7 and sealing ring 8；On described
Spool 3 be it is discoid, there is installation through-hole 31 at the axle center of upper valve core 3, the periphery of installation through-hole 31 has ventilative through hole 32, on
The lower surface of spool 3 has the installation base 33 extended downwardly, and the sealing ring 8 is set on installation base 33；The lower valve
Core 4 includes discoid piston portion 41 and the round bar portion for being arranged at 41 axle center of piston portion and extending up through installation through-hole 31
42, the end in the round bar portion 42 has installation detent, and the setting of circlip 7 is in installation detent；The interior pressing spring 6 is arranged
In 42 periphery of round bar portion, one end is fixedly connected with circlip 7, and the other end is contacted with the upper surface of upper valve core 3；The outer pressing spring 5 is set
It sets between valve deck 2 and upper valve core 3, one end is abutted with the lower surface of valve deck 2, and the other end is contacted with the upper surface of upper valve core 3.
Further, the ventilative through hole 32 is circular hole, is set in the way of circumference array using the axle center of upper valve core 3 as dot
There are six；It is uniformly provided with ventilative through hole, the liquids and gases when resetting of upper valve core 3 are avoided uniformly through upper valve core 3
Upper valve core 3 cannot smoothly be resetted because pressure is uneven, improve the combination precision between sealing ring 8 and valve body 1.
Further, there is cambered surface portion 12, the overflow hole 11 is arranged in cambered surface portion 12 on the valve body 1；By setting
Cambered surface portion 12 is set, when gas or liquid pass through cambered surface portion 12 in overflow, flowing is gentler, prevents air pressure from rising suddenly and sharply and damaging
Overflow valve.
Further, it is equipped with corner portion on the surface that the valve deck 2 and valve body 1 contact, appearance is more beautiful, and installation is more
It is more convenient when changing.
