Abstract
The utility model relates to the technical field of valves, in particular to a two-position three-way valve. The two-position three-way valve comprises a valve body and a valve element seat arranged on the valve body; a gas inlet, a valve cavity and a gas outlet are formed in the valve body; the gas inlet is communicated with the valve cavity by a valve port; the gas outlet is communicated with the valve cavity; a valve element is arranged in the valve cavity in an up-and-down movable manner; the upper end of the valve element passes through a through hole formed in the valve element seat to extend out of the valve element seat; a vent hole is longitudinally formed in the valve element; a compression spring is arranged between the valve element and the valve body; a sealing seat is arranged at the position, which is close to the valve port, in the gas inlet in the up-and-down movable manner; a reed is fixedly arranged in the gas inlet; and a reed is fixedly arranged in the gas outlet. The two-position three-way valve has a simple structure and is very convenient to operate; and a joint does not need to be arranged on the valve body.
Description
Technical field
The utility model 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 valve body, and loading and unloading are inconvenient, waste time and energy, and are necessary existing two position three-way valve is effectively improved.
The model utility content
The purpose of this utility model is for the defective of prior art and deficiency, a kind of compact structure is provided, arranges rationally, connects two position three-way valve easy to loading and unloading.
For achieving the above object, the utility model is by the following technical solutions:
a kind of two position three-way valve described in the utility model, comprise valve body, be provided with the valve core case on valve body, form suction port on 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 described valve pocket and be provided with spool, described spool upper end is passed the through hole of being located on valve core case and is stretched out outside valve core case, vertically be provided with exhaust port in spool, be provided with Compress Spring between described spool and valve body, the interior close valve port of described suction port place can be provided with sealing seat up or down, be fixed with reed in described suction port, be fixed with reed in described air outlet.
Further, described two reeds are fixed in suction port and 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 air outlet.
The utility model beneficial effect is: be fixed with reed in suction port described in the utility model, be fixed with reed in described air outlet, described reed is mainly used in card and establishes insertion flexible pipe tube head of the present utility model.The utility model is simple in structure, and is easy to operate, do not need to arrange connecting head on valve body.
Description of drawings
Fig. 1 is sectional structure schematic diagram of the present utility model.
In figure:
1, valve body; 2, seal ring; 3, packing ring; 4, reed;
5, sheath; 6, suction port; 7, air outlet; 8, valve port;
9, spool; 10, exhaust port; 11, valve core case; 12, valve pocket;

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of two position three-way valve described in the utility model comprises valve body 1, is provided with the valve core case 11 on valve body 1, and above-mentioned two parts consist of the utility model agent structure.
Be provided with Compress Spring 13 between described spool 9 and valve body 1, described suction port 6 is interior can be provided with sealing seat 14,14 one-tenth corresponding settings of described exhaust port 10 and sealing seat up or down near valve port 8 places.
Be fixed with reed 4 in described suction port 6, be fixed with reed 4 in described air outlet 7.Described two reeds 4 are fixed in suction port 6 and air outlet 7 by two packing rings 3 respectively.Described two packing ring 3 inboards are equipped with seal ring 2.The outer sheath 5 that is equipped with in described suction port 6 and air outlet 7.
Working principle: as shown in Figure 1, the utility model 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 to open the utility model, downward pressure valve core 9, spool 9 bottoms promotion sealing seats 14 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 utility model 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 utility model recovers closed condition.
The above is only better embodiment of the present utility model, therefore all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
