Description
Technical field
The utility model belongs to the Fluid-transmission field, a kind of two-position three way mechanical valve particularly.
Background technique
In the Fluid-transmission control loop, two position three-way valve is a kind of control valve class base components of using often.Two position three-way valve generally has three fluid delivery ports, and wherein two is the working position, by changing the position of spool, makes three fluid delivery ports change connected relation, realizes different fluid control purposes.Existing use is two-position three way magnetic valve comparatively widely, produces magnetic force by electrical signal control electromagnet and inhales movable valve plug change position, realizes the control effect of two position three-way valve.This solenoid valve need to use electromagnetic control apparatus, although the control effect is pretty good, make valve body structure comparatively complicated, and cost is high, is not suitable for cheaply liquid control system.
The model utility content
The purpose of this utility model provides the two-position three way mechanical valve, and it is simple that it has a valve body structure, and the low advantage of cost.
To achieve these goals, the technical solution adopted in the utility model is as follows: the two-position three way mechanical valve, comprise valve body, and the import, outlet and the working hole that are opened in confession fluid turnover on the valve body, it is characterized in that, described import and outlet are positioned at valve body both sides relative position, and import is provided with annular spacer ring with the outlet connecting part in the valve body; Spool is slidably mounted in the outlet, and the center of the described spacer ring of nozzle alignment of spool is equipped with on the nozzle between the spacer ring that Returnning spring withstands on spool and valve body; Offer the passage that is communicated with working hole near the spacer ring place in the described outlet; Is provided with the seal ring that can in import, move near the spacer ring place in the described import, and described seal ring can be isolated import and outlet after being adjacent to spacer ring.
Preferably, described spool is installed in the described outlet by valve seat, and the end of described spool offers the exhaust port of transverse opening, but has the coating circle of closed grate hole on the described valve seat.
Preferably, described valve core upper sleeve is equipped with O shape circle.
Preferably, the end of described passage is provided with steel ball.
Preferably, described import and working hole place all are equipped with straight-through type pipe joint, and are equipped with sheath on the pipe joint.
Preferably, E shape circle, packing ring and reed are installed successively from inside to outside in described import and the working hole, described reed is positioned at the position near pipe joint.
Preferably, also be provided with pad in the described import, it is inboard that described pad is positioned at E shape circle.
Compared with prior art, two-position three way mechanical valve of the present utility model, can be by arbitrarily external force input, after making spool move to range in the valve body, the nozzle of spool passes spacer ring and enters in the import of valve seal ring is backed down, import this moment communicates with spool, and spool and channel connection, makes import and operable communication; Certainly after shedding the external force spool and unclamping, spool resets under the elastic force of Returnning spring, and nozzle no longer withstands seal ring, so seal ring seals between moving inward import and nozzle under the inlet fluid pressure, this moment, working hole kept being communicated with spool, i.e. outlet is communicated with working hole.By above-mentioned valve body structure, can realize changing valve element position, realize the control effect of two-position three way.Therefore the utility model not only can reach the control effect of two-position three way magnetic valve, and it is simple also to have a valve body structure, and the low advantage of cost.

Embodiment
Below in conjunction with accompanying drawing and embodiment the technical solution of the utility model is described.
As shown in Figure 1, the utility model is a kind of two-position three way mechanical valve, comprise valve body 10, and the import 11, the outlet 12 and working hole 13 that are opened in confession fluid turnover on the valve body 10, described import 11 is positioned at valve body 10 both sides relative positions with outlet 12, and valve body 10 interior imports 11 are provided with annular spacer ring 14 with outlet 12 connecting parts; Spool 20 is slidably mounted in the outlet 12, and the nozzle of spool 20 21 is aimed at the center of described spacer ring 14, is equipped with on the nozzle 21 between the spacer ring 14 that Returnning spring 22 withstands on spool 20 and valve body 10; Described outlet 12 interior close spacer ring 14 places offer the passage 15 that is communicated with working hole 13; Interior being provided with near spacer ring 14 places of described import 11 can be at the seal ring 30 of import 11 interior movements, and described seal ring 30 can be with import 11 and outlet 12 isolation after being adjacent to spacer ring 14.Compared with prior art, two-position three way mechanical valve of the present utility model, can be by arbitrarily external force input, after making spool 20 move to range in the valve body 10, the nozzle 21 of spool 20 passes spacer ring 14 and enters into that the import 11 of valve is interior backs down seal ring 30, import 11 this moment communicates with spool 20, and spool 20 is communicated with passage 15, makes import 11 and operable communication; Certainly after shedding external force spool 20 and unclamping, spool 20 resets under the elastic force of Returnning spring 22, nozzle 21 no longer withstands seal ring 30, therefore seal ring 30 seals between moving inward import 11 and nozzle 21 under import 11 hydrodynamic pressures, this moment, working hole 13 kept being communicated with spool 20, namely exported 12 and was communicated with working hole 13.By above-mentioned valve body 10 structures, can realize changing spool 20 positions, realize the control effect of two-position three way.Therefore the utility model not only can reach the control effect of two-position three way magnetic valve, and it is simple in structure also to have a valve body 10, and the low advantage of cost.In addition, the utility model also has another advantage, is it can be used as position limit switch, make stroke part top position spool 20 arrive predetermined stroke after, can change the connected relation of two-position three way mechanical valve, play the effect of position limit switch control.
For make spool 20 with the outlet 12 connected states be controlled to promote control effect of the present utility model, described spool 20 is installed in the described outlet 12 by valve seat 23, and the end of described spool 20 offers the exhaust port 24 of transverse opening, but the coating circle 25 that has closed grate hole 24 on the described valve seat 23, certainly make spool 20 deeper enter into valve body 10 when interior by external force, exhaust port 24 just enters into to coat in the circle 25 it is closed.For the lift-off seal effect, preferably, be equipped with O shape circle 40 on the described spool 20; Preferably, the end of described passage 15 is provided with steel ball 16; Preferably, E shape circle 70, packing ring 80 and reed 90 are installed successively from inside to outside in described import 11 and the working hole 13, described reed 90 is positioned at the position near pipe joint 50; Preferably, also be provided with pad 17 in the described import 11, described pad 17 is positioned at E shape and encloses 70 inboards.In addition, for convenient use of the present utility model, preferably, described import 11 all is equipped with straight-through type pipe joint 50 with working hole 13 places, and is equipped with sheath 60 on the pipe joint 50, makes three mouths of valve body 10 convenient when connecting tube.
Two-position three way mechanical valve of the present utility model, it is simple that it has a valve body structure, and the low advantage of cost.
