Description
Technical field
The present invention is a kind of four-way change-over valve parts, especially is related to the material and the composite structure thereof 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 working medium, realizes the function that heat pump type air conditioner system refrigeration in summer, winter heat, and it also can be used for the defrost effect of heat pump type air conditioner system simultaneously.
The structure of relevant four-way change-over valve and application thereof have detailed explanation in notification number is the Chinese utility model patent specification of CN2654975Y, do not repeat them here.
Shown in Fig. 1～4, the valve body of main valve 61 of existing electromagnetism four-way change-over valve is a tubular member, is connected with valve seat 7 and C, D, E, four of S on it and takes over 52: four and take over the inners and be inserted among the valve hole 51a, fuses by soldering then and keeps sealing; Wherein valve seat 7 arc surfaces and valve body of main valve 61 internal surfaces are fitted, and the inner that E, S, C take over is passed corresponding valve hole and is inserted in the corresponding valve seat orifice, by soldering three adapter, valve seat 7 and 61 parts of valve body of main valve are fused and keep sealing.
The general structure of existing electromagnetism four-way change-over valve as shown in Figure 2, fuse by soldering with end cap 8 and valve body of main valve 61 and keep sealing, other structure and notification number are that the Chinese utility model patent specification of CN2654975Y is disclosed similar, do not repeat them here.
The material that existing product is made valve body and end cap is a brass, and E, S, C, D take over and the manufactured materials of capillary tube 8 is a red copper.Because copper has good heat-conductive characteristic, so the thermal loss that such four-way change-over 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.
In addition, the spout diameter of the adapter that existing product uses is consistent with the internal diameter of position, intermediate portion, is unfavorable for that the assembling of system's pipe arrangement is inserted, and the inflow of scolder when welding.
Summary of the invention
The technical assignment of the technical problem to be solved in the present invention and proposition is to overcome factor when the working thermal loss relatively large defective of existing product because of manufactured materials, a kind of relatively four-way reversing valve for heat pump air conditioner of the more weak made refrigeration working medium main member of flowing through of heat-conductive characteristic that utilizes is provided, for this reason, the present invention is by the following technical solutions:
A kind of four-way reversing valve for heat pump air conditioner, comprise main valve, pilot valve and coil, be connected with capillary tube between main valve and the pilot valve, offer through hole on the valve body of main valve, the through hole is connected with adapter, it is characterized in that: described valve body of main valve is made by stainless steel material, described adapter is for comprising internal layer and outer field composite pipe, described skin is a stainless steel, described internal layer is a red copper, and the end of taking over outwards is folded into the flanging that coincide with described valve body of main valve outer surface, and described flanging is welded on the outer surface of the valve body of main valve around the corresponding through hole.Relative red copper, stainless steel has more weak heat-conductive characteristic, the four-way change-over valve of Xing Chenging thus, exposed outside at the main position that its refrigeration working medium is flowed through by stainless steel material, effectively reduced thermal loss, guaranteed that adapter is connected with the reliable of valve body and take over terminal flanging, improved the solder yield of product; And the red copper internal layer of taking over has continued the structure that the prior art red copper is taken over, and is convenient to be connected with other member of air-conditioning system, the feasible four-way change-over valve that is made by this scheme is the same with existing product have and other constituent element of air-conditioning system between matching.
As the further of technique scheme improved and replenish, the present invention also comprises following additional technical feature:
Described four-way reversing valve for heat pump air conditioner is characterized in that: described flanging is fitted with the outer surface of valve body of main valve fully towards the one side of valve body of main valve.
Described four-way reversing valve for heat pump air conditioner is characterized in that: the mouth of pipe of described adapter front end is bell mouth shape, and connection is inserted in the assembling that is beneficial to system's pipe arrangement.
Described four-way reversing valve for heat pump air conditioner is characterized in that: described capillary tube is a Stainless Steel Tube.
The invention has the beneficial effects as follows:
By changing the material and the composite structure thereof of adapter, valve body, valve seat, help reducing the radiation loss of four-way change-over valve in heat pump type air conditioning system, and help taking over the welding with valve body, improve solder yield, thereby enhance productivity.
