Abstract
The invention relates to a valve, in particular to an inserting-installation type two-way valve. The problem that when sharp leakage occurs in a certain pressure vessel, the connected pressure vessels cannot work normally is solved during the usage of a plurality of existing pressure vessels connected in a series-parallel mode. The inserting-installation type two-way valve is composed of a left stopping sheet, a valve seat, a left valve core, a seal ring, a clamp spring, a right valve core, a valve body and a right stopping sheet. The left valve core and the left stopping sheet are respectively installed in a valve seat hole, the right valve core and the right stopping sheet are respectively installed in a valve body hole, a valve body provided with the right valve core and the right stopping sheet is inserted into the valve seat inner hole provided with a left valve core and the left stopping sheet, moreover the valve body and the valve seat inner hole are connected together through the clamp spring, and the seal ring is arranged between the valve seat and the valve body. The inserting-installation type two-way valve is used for series-parallel connection of a plurality of pressure vessels and has the advantages of being compact in structure, convenient to assemble and disassemble and capable of ensuring normal work of the pressure vessels.
Description
Technical field
The present invention relates to a kind of valve, particularly a kind of plug-in type two-way valve.
Background technique
In the using process of a plurality of pressurized container series and parallel, when certain pressurized container generation self-destruction or sharply leakage, when moment, pressure trended towards zero, continuous pressurized container is influenced by it can't proper functioning.In the prior art, be a vacancy at the two-way valve of corresponding problem.
Summary of the invention
The objective of the invention is provides a kind of plug-in type two-way valve in order to overcome the shortcoming of prior art, solve in existing a plurality of pressurized container series and parallel using process, and when certain pressurized container takes place sharply to leak, the problem that continuous pressurized container can't proper functioning.
Technological scheme of the present invention for achieving the above object is:
A kind of plug-in type two-way valve is characterized in that: described plug-in type two-way valve is made up of left catch, valve seat, left spool, seal ring, jump ring, right spool, valve body and right catch; Described left spool is respectively charged in the corresponding coaxial aperture of described valve seat at interior, left catch outside, and with valve seat and left catch periphery riveting jail; Described right spool is respectively charged in the corresponding coaxial aperture of described valve body at interior, right catch outside, and with valve body and right catch periphery riveting jail; The valve body that right spool, right catch are housed inserts and is equipped with in the valve seat endoporus of left spool, left catch, and links together by described jump ring, is provided with described seal ring between described valve seat and the valve body.
When p1 〉=p2 or p1≤p2 certain value, spool is positioned at the neutral position, and two-way valve is in opening state.
When p1＞p2 surpassed certain value, spool moved and the closed valve seat hole to the p2 direction under the p1 effect, makes two-way valve be in cut-off state.
When p1＜p2 surpassed certain value, spool moved and the draught excluder body opening to the p1 direction under the effect of p2, makes two-way valve be in cut-off state.
The present invention compared with prior art because the pressure signal (p1, p2) that has adopted technique scheme, this two-way valve spool to receive respectively to transmit at two ends, realizes that by the side-to-side movement of spool pressure equates or relative mistake is in opening state when certain value; Be in cut-off state during greater than certain value.
The present invention is used for a plurality of pressurized container series parallel connection, has compact structure, and volume is little, and is in light weight, is convenient to assembly and disassembly, can guarantee the advantage of pressurized container proper functioning.

Embodiment
Below in conjunction with accompanying drawing optimum implementation of the present invention is described further.
As shown in Figure 1, a kind of plug-in type two-way valve is made up of left catch 1, valve seat 2, left spool 3, seal ring 4, jump ring 5, right spool 6, valve body 7 and right catch 8; Described left spool 3 is respectively charged in the described valve seat 2 corresponding coaxial apertures at interior, left catch 1 outside, and with valve seat 2 and left catch 1 peripheral riveting jail; Described right spool 6 is respectively charged in the described valve body 7 corresponding coaxial apertures at interior, right catch 8 outside, and with valve body 7 and right catch 8 peripheral riveting jails; The valve body 7 that right spool 6, right catch 8 are housed inserts in the endoporus of the valve seat 2 that left spool 3, left catch 1 are housed, and links together by described jump ring 5, is provided with described seal ring 4 between described valve seat 2 and the valve body 7.
As shown in Figure 1: when p1 〉=p2 or p1≤p2 certain value, left spool 3 and right spool 6 are positioned at the neutral position, and two-way valve is in opening state.
As shown in Figure 2, it is characterized in that: when p1＞p2 surpassed certain value, left spool 3 moved and closed valve seat 2 holes to the p2 direction under the p1 effect, makes two-way valve be in cut-off state.
As shown in Figure 3, it is characterized in that: when p1＜p2 surpassed certain value, right spool 6 moved and closed valve 7 holes to the p1 direction under the effect of p2, makes two-way valve be in cut-off state.
Its working principle is: when p1 〉=p2 certain value, left side spool 3 and right spool 6 are positioned at the neutral position, two-way valve is in opening state, the high relatively p1 of pressure by the peripheral slit of catch 1 aperture valve seat, 2 holes and left spool 3 and valve body 7 holes and right spool 6 again by right catch 8 orifice flows to p2.When p1＞p2 surpassed certain value, left spool 3 moved and closed valve seat 2 holes to the p2 direction under the effect of p1, makes two-way valve be in cut-off state; When p1≤p2 certain value, right spool 6 and left spool 3 are positioned at the neutral position, and two-way valve is in opening state, the high relatively p2 of pressure by catch 8 aperture valve bodies, 7 holes and right spool 6 and valve seat 2 holes and left spool 3 peripheral slits again by catch 1 orifice flow to p1.When p2＞p1 surpassed certain value, right spool 6 moved and closed valve 7 holes to the p1 direction under the p2 effect, makes two-way valve be in cut-off state.
The valve seat 2 and the valve body 7 that right spool 6, right catch 8 are housed of left spool 3, left catch 1 are housed, can be used as one-way valve and independently use.
