Abstract
The invention relates to the technical field of valves, in particular to a two-position three-way valve, which comprises a valve body and a spool socket arranged on the valve body, wherein an air inlet, a valve chamber and an air outlet are formed in the valve body; the air inlet is communicated with the valve chamber through a valve port; the air outlet is communicated with the valve chamber; a spool is vertically movably arranged in the valve chamber; the top end of the spool passes through a through hole formed in the spool socket and extends out of the spool socket; an air vent is formed in the spool in the vertical direction; a compression spring is arranged between the spool and the valve body; a sealing socket is vertically movably arranged in the air inlet in a position close to the valve port; a reed is fixedly arranged in the air inlet; and a reed is fixedly arranged in the air outlet. The two-position three-way valve is simple in structure and rather easy to operate, and a connector is not required to be arranged on the valve body.
Description
Technical field
The present invention relates to valve class technical field, particularly a kind of two position three-way valve.
Background technique
Two position three-way valve is a kind of of valve body, and is well known common.Existing two position three-way valve is unreasonable because structure arranges, and during connecting pipeline, needs to be equipped with the production joint that is used for connection on the valve body, and loading and unloading are inconvenient, waste time and energy, and are necessary existing two position three-way valve is effectively improved.
Summary of the invention
The object of the invention is to defective and deficiency for prior art, a kind of compact structure is provided, arranges rationally, connect two position three-way valve easy to loading and unloading.
For achieving the above object, the present invention is by the following technical solutions:
A kind of two position three-way valve of the present invention, comprise valve body, be provided with the valve core case on the valve body, form suction port on the described valve body, valve pocket and air outlet, described suction port is communicated with valve pocket by valve port, described air outlet is communicated with valve pocket, can move up and down in the described valve pocket and be provided with spool, described spool upper end is passed the through hole of being located on the valve core case and is stretched out outside the valve core case, vertically is provided with exhaust port in the spool, be provided with Compress Spring between described spool and the valve body, can be provided with up or down sealing seat near the valve port place in the described suction port, be fixed with reed in the described suction port, be fixed with reed in the described air outlet.
Further, described two reeds are fixed in suction port and the air outlet by two packing rings respectively.
Further, described two packing ring inboards are equipped with seal ring.
Further, be equipped with sheath outside described suction port and the air outlet.
Beneficial effect of the present invention is: be fixed with reed in the suction port of the present invention, be fixed with reed in the described air outlet, described reed is mainly used in card and establishes insertion flexible pipe tube head of the present invention.The present invention is simple in structure, and is easy to operate, do not need at valve body connecting head to be set.

Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of two position three-way valve of the present invention comprises valve body 1, is provided with the valve core case 11 on the valve body 1, and above-mentioned two parts consist of agent structure of the present invention.
Be provided with Compress Spring 13 between described spool 9 and the valve body 1, described suction port 6 interior close valve port 8 places can be provided with sealing seat 14,14 one-tenth corresponding settings of described exhaust port 10 and sealing seat up or down.
Be fixed with reed 4 in the described suction port 6, be fixed with reed 4 in the described air outlet 7.Described two reeds 4 are fixed in suction port 6 and the air outlet 7 by two packing rings 3 respectively.Described two packing ring 3 inboards are equipped with seal ring 2.Described suction port 6 and the air outlet 7 outer sheaths 5 that are equipped with.
Working principle: as shown in Figure 1, the present invention is in closed condition at this moment, and sealing seat 14 seals up valve port 8, and suction port 6 is not communicated with valve pocket 12, and exhaust port 10 is communicated with air outlet 7.When needing unlatching of the present invention, downward pressure valve core 9, spool 9 bottoms promote sealing seat 14 and move down, and valve port 8 is opened, and suction port 6 is communicated with air outlet 7 by valve pocket 12, sealing seat 14 seal vents 10, the present invention is in opening state.At this moment, Compress Spring 13 is in compressive state.In the time of need closing, unclamp spool 9, spool 9 moves under the effect of Compress Spring, and sealing seat 14 separates with exhaust port 10 and seals valve port 8, and the present invention recovers closed condition.
The above only is preferred embodiments of the present invention, so all equivalences of doing according to the described structure of patent claim of the present invention, feature and principle change or modify, is included in the patent claim of the present invention.
