Abstract
The invention discloses a four-way reversing valve for a heat pump air-conditioner. The four-way reversing valve comprises a main valve, a pilot valve and a coil, wherein the main valve comprises a main valve body, a valve seat, a first connecting pipe, a second connecting pipe, a third connecting pipe and a fourth connection pipe; a circular connector is arranged on one side face of the main valve body, while a square connector is arranged on the other side face of the main valve body; the main valve body, the valve seat and the second, third and fourth connecting pipes are all made of stainless steel materials; the second, third and fourth connecting pipes are inserted into three valve seat ports of the valve seat; the valve seat is pressed on the square connector of the main valve and the edge of the valve seat is jointed with that of the square connector; and the valve seat is formed by plates by stamping. The four-way reversing valve not only is reduced in material cost, in process cost and in solder cost, but also advantageous to reducing the heat dissipation losses of the four-way reversing valve in a heat-pump air-conditioning system, by changing the materials of the valve body, the valve seat and the connecting pipes and the combining process and structure thereof; and therefore, the energy efficiency of the air-conditioning system is improved.

[technical field]
The present invention relates to the four-way change-over valve parts, relate in particular to the improvement of four-way change-over valve parts in the heat pump type air conditioning system.
[background technique]
Four-way change-over valve is used for heat pump type air conditioner system, by changing the flow direction of refrigeration agent, realizes heat pump type air conditioner system refrigeration, the function that heats, and it also can be used for the defrost effect of heat pump type air conditioner system simultaneously.
Shown in Fig. 1,2A, 2B, 3A, 3B, 4, existing electromagnetism four-way change-over valve comprises main valve 1, pilot valve 3 and coil 4 three parts, and the main valve body 11 of main valve 1 is a tubular member, wherein has valve seat 51, ECS three adapters 61 and D to take over 21; Take over the inners for four and be inserted into respectively among valve hole 11a and the 11b, fuse by soldering then and keep sealing; Wherein valve seat 51 arc surfaces and valve body of main valve 11 internal surfaces are fitted, ECS three takes over the inner of 61 and passes corresponding valve hole through hole 11a and be inserted in the corresponding valve seat orifice, again by soldering with ECS three take over 61, valve seat 51 and main valve body 11 fuse and keep sealing.
Existing valve seat 51 is D shape copper rod fine finishing moulding of adopting moulding, the processing technology complexity.
The general structure of existing electromagnetism four-way change-over valve as shown in Figure 4, end cap and main valve body 11 fuse by soldering and keep sealing.All need use scolder during above-mentioned these solderings, scolder cost height existingly simultaneously welds all gas brazings of usefulness, has welding powder and valve body oxidation must carry out pickling, processing technology complexity on the main valve body 11 of welding back.
The material that existing four-way change-over valve is made main valve 1, valve seat 51, end cap is a brass, and the manufactured materials that E, C, S, D take over is a red copper.Because copper has good heat-conductive characteristic, so the thermal loss that such four-way valve produces in system is relatively large, and this thermal loss is directly proportional with the surface area at the mobile position of refrigeration working medium, and four-way change-over valve is in naked state in use.

As preferably, adopt argon arc welding or laser beam welding to be welded to connect between the 234 adapter and the valve seat mouth.
As preferably, valve seat and square connection mouth adopt argon arc welding or laser beam welding to be welded to connect.
As preferably, first takes over and is made by the red copper material, adopts soldering to be welded to connect with the circular connection mouth of main valve body.
As preferably, first takes over and is made by stainless steel material, adopts argon arc welding or laser beam welding to be welded to connect with the circular connection mouth of main valve body.
As preferably, the centre of described valve seat is plane, two ends bending, and section is ' [' type shape.
As preferably, the material of the valve seat that described punching press is made is copper coin or corrosion resistant plate.
Beneficial effect of the present invention: the present invention is by changing material and the group technology and the structure of valve body, valve seat, adapter, cost of material descends, the technology cost descends, the scolder cost descends, also help reducing the radiation loss of four-way change-over valve, thereby improve the efficiency of air-conditioning system at heat pump type air conditioning system.
Feature of the present invention and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
