In order to solve the technical problem, the utility model provides a following technical scheme:

the utility model relates to a rely on local material to warp and spacing direct action type sequence valve, including the plug, plug threaded connection is at the upper surface opening part of valve body, the inside joint of upper surface opening part of valve body has the disk seat, the disk seat joint is at the upper surface opening part of valve body, the bottom fixedly connected with of disk seat has the sealing washer, the inside joint of disk seat has the steel ball, the steel ball corresponds with the through-hole of seting up bottom the disk seat, the spring holder has been seted up to the bottom of plug, the inside joint of spring holder has the spring, the lower extreme and the steel ball in close contact with of spring, it has the case to peg graft in the inside of valve body, a plurality of triangle pieces of lower extreme fixedly connected with of plug.

As an optimal technical scheme of the utility model, the bottom and the disk seat in close contact with of plug, the disk seat closely laminates with the valve body.

As an optimal technical scheme of the utility model, it is a plurality of three hornblocks equidistance fixed connection is at the plug lower surface, and is a plurality of three hornblocks are corresponding with the upper surface of disk seat.

As a preferred technical scheme of the utility model, the fixed dog that has cup jointed in upper surface opening part bottom of valve body, disk seat and dog in close contact with, the interval has been seted up between dog and the case.

As an optimized technical scheme of the utility model, the material of triangle piece is soft rubber.

The utility model discloses the beneficial effect who reaches is: because the plug stress point mainly concentrates on the closed angle of bottom triangle, and the material of triangle-shaped piece is soft rubber, therefore can be when moment is bigger than normal, most deformation mainly produces at triangular closed angle position, rather than on the main valve hole, becomes triangle-shaped through plug bottom structure and carries on spacingly to make this valve can effectively solve the influence that moment value size caused the product, improve the experimental qualification rate of product then.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example (b): as shown in fig. 1, the utility model relates to a rely on local material to warp and spacing direct action type sequence valve, including plug 1, 1 threaded connection of plug is at the upper surface opening part of valve body 8, the inside joint of upper surface opening part of valve body 8 has disk seat 5, 5 joints of disk seat are at the upper surface opening part of valve body 8, the bottom fixedly connected with of disk seat 5 has sealing washer 6, the inside joint of disk seat 5 has steel ball 4, the through-hole that steel ball 4 and 5 bottoms of disk seat were seted up corresponds, spring holder 3 has been seted up to the bottom of plug 1, the inside joint of spring holder 3 has spring 2, spring 2's lower extreme and 4 in close contact with of steel ball, valve element 2 has been pegged graft to the inside of valve body 8, a plurality of triangle-blocks 9 of lower extreme.
