Abstract

The utility model discloses a novel connecting structure of a four-way valve D connecting pipe and a stainless steel pilot valve. The connecting structure comprises a main valve, a stainless steel pilot valve, a bracket connecting frame, a D connecting pipe and an another connecting pipe, wherein the D connecting pipe is connected with the main valve in a manner of arc transition, and the center line of the D connecting pipe doesn't share the same line with that of the another connecting pipe. The included angle between the center line of the D connecting pipe and that of another connecting pipe ranges from 90 to 135 DEG. The included angle between the center line of the bracket connecting frame and that of another connecting pipe is 45 DEG. In the utility model, the position of the D connecting pipe is changed to provide the stainless steel pilot valve and the bracket connecting frame without changing performance and energy consumption of other parts, and the D connecting pipe is shortened by changing the original structure; and the connecting structure has simple scheme and low transformation cost.

Description

Novel cross valve D takes over and stainless steel pilot valve syndeton

Technical field:

The utility model relates to the air conditioner refrigerating technical field, especially relates to the electromagnetism four-way change-over valve that uses on the heat pump air conditioner.

Background technology:

The electromagnetism four-way change-over valve that heat pump air conditioner uses mainly comprises several parts of solenoid, pilot valve and main valve.The effect that red copper is wherein taken over (D/E/S/C adapter) mainly provides the path that refrigerant moves.Under the background that at present the copper valency progressively goes up, become the principal element that influences the cross valve cost as the brass and the red copper of cross valve important raw and processed materials.

See illustrated in figures 1 and 2: existing cross valve D commonly used takes over 04 and is " J " type, its not flared end link to each other with main valve 01 valve body, there is an end of enlarging to link to each other with compressor, D take over 04 with S to take over 05 welding junction angle be 180 degree to dodge the shared space of pilot valve 02 and support link 03, therefore the total length of D adapter 04 is longer, the copper material that consumes is more, and is unfavorable for the production cost that reduces cross valve.

The utility model content:

The purpose of this utility model provides a kind of novel cross valve D to take over and stainless steel pilot valve syndeton with regard to being the weak point that exists at prior art, it can effectively shorten the length that D takes over, reduce material cost, also reduce the usage space of cross valve in air-conditioner outdoor unit simultaneously.

For achieving the above object, novel cross valve D of the present utility model takes over stainless steel pilot valve syndeton and includes main valve, stainless steel pilot valve, support link, D adapter, other adapter, wherein, the stainless steel pilot valve is between D adapter and main valve, D take over main valve between is connected with the arc transition form, the center line of D adapter and the center line of other adapter be not on same straight line.

Preferred as technique scheme, the center line that described D takes over is between 90 degree～135 are spent with the center line angle of other adapter.

Preferred as technique scheme, the center line of described support link and other angle of taking over center line are 45 to spend.

The beneficial effects of the utility model are: it is under the situation that does not change other component capabilities, energy consumption, the position that D is taken over changes and stainless steel pilot valve and support link is provided, reduced the D connecting pipe length by the change to original structure, scheme is simple, and improvement cost is low.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1 is the structural representation of existing cross valve;

Fig. 2 is the side view of Fig. 1;

Fig. 3 is a structural representation of the present utility model;

Fig. 4 is the side view of Fig. 3.

The specific embodiment:

See Fig. 3 and shown in Figure 4: novel cross valve D of the present utility model takes over stainless steel pilot valve syndeton and includes that main valve 10, stainless steel pilot valve 20, support link 30, D take over 40, other takes over 50 (E/S/C, do not comprise solenoid), wherein, stainless steel pilot valve 20 is between D adapter 40 and main valve 10, D take over 40 with main valve 10 between be connected with the arc transition form, the bending angle becomes one by two, and the center line of D adapter 40 and other are taken over 50 center line not on same straight line.Because the gas because of the compressor ejection when cross valve is worked in air-conditioning system rushes at slide block, when D takes over the center line angle of 40 center line and other adapter 50 when 90 spend, because the pressure of air-flow might cause slide block to blow, between slide block and slide, produce the gap and cause leakage, therefore the center line angle of the center line of D adapter 40 and other adapter 50 is advisable between 90 degree～135 degree, so neither can blow slide block and cause leakage, can shorten the length of D adapter 40 again, vacate the position for stainless steel pilot valve 20 is inserted in coil, also reduced the usage space of cross valve in air-conditioner outdoor unit simultaneously.

In addition, stainless steel pilot valve 20 move to D take over 40 and main valve 10 with interior space, reduce the angle that the S in D adapter 40 and other adapter 50 takes over, made D take over 40 length own and shorten greatly, reduced the material cost of stainless steel pilot valve 20 and support link 30 simultaneously.

The angle that the center line of support link 30 and other are taken over 50 center lines is 45 degree, for the length that shortens D adapter 40 has increased the space, has also reduced the usage space of cross valve in air-conditioner outdoor unit simultaneously.

The above only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model, and every equalization of doing according to the utility model changes with modifying and all belongs in the claim that the utility model contains.
