Abstract
The utility model discloses a main valve of a stainless steel four-way reversing valve, which comprises a main valve body, a main valve seat, a D connecting tube, a E connecting tube, an S connecting tube and a C connecting tube. The D connecting tube is welded at the upper end of the main valve body; an embedded groove is concavely arranged at the lower end of the main valve body; the main valve seat is arranged in the embedded groove and is hermetically connected with the main valve body through a welding mode; and the E connecting tube, the S connecting tube and the C connecting tube are matched with a mounting hole arranged on the main valve seat and are hermetically connected with the main valve seat through the welding mode. In the main valve of the stainless steel four-way reversing valve, the embedded groove used for mounting the main valve seat is arranged on the main valve body so that the machining technology of the main valve body can be simplified and the welding part of the main valve can realize an individualized connection of materials, thereby enlarging the optical range of a welding flux. Moreover, welding of the parts one by one is adopted, so that the selection of welding methods can be diversified, and the welding temperature of a copper connecting tube and the main valve seat can be controlled at a lower level, thereby avoiding the problems that the grain size of the copper connecting tube is thick, big and the like.
Description
Technical field:
The utility model relates to a kind of main valve of stainless steel four-way change-over valve.
Background technique:
The electromagnetism four-way change-over valve is a critical elements of air-conditioning system, and traditional four-way change-over valve adopts copper material to make the main structure of valve body.The four-way change-over valve made by stainless steel material has also appearred on the market in recent years, because stainless property, the efficiency that it can improve air conditioner in use makes air conditioner that certain energy saving space be arranged, therefore, the stainless steel four-way change-over valve has market prospects preferably.
But, the welding of present stainless steel four-way change-over valve ubiquity bigger difficulty, especially main valve when producing.See shown in Figure 1: the main valve of existing stainless steel four-way change-over valve mainly includes main valve body 01, main valve seat 02, D adapter 03, E adapter 04, S adapter 05, C adapter 06; Wherein, D takes over 03 and is welded on main valve body 01 upper end, and main valve seat 02 is fitted on the valve pocket inwall of cylindrical main valve body 01, by centre distance realization centering location, adapter hole, thereby the assembling that realizes main valve body 01, main valve seat 02 and E adapter 04, S adapter 05, C adapter 06 connects.Because the weld assembly of main valve is more, traditional welding procedure is main valve body 01, main valve seat 02, E adapter 04, S adapter 05, C to be taken over 06 carry out the one welding earlier, welds D again and takes over 03, welds pilot valve capillary tube and main valve end cap at last.When actual production, main valve welding makes its cost of production, welding quality be a greater impact because of restriction such as selected for use by scolder, welding method is selected for use.When selecting gas brazing for use,, make the hot area of main valve body 01 bigger, and be exposed to air ambient under and weld, make stainless steel surfaces oxidized and cause solder can't be full of weld seam, thereby influence weldquality because of need carry out integral body heating to main valve seat 02; When adopting furnace brazing, select the higher scolder of welding temperature for use because of need and weld, and the stove weldering is whole heating, can make the grain size of copper connecting tube generally thicker, can't satisfy the usability of product.
The model utility content:
The purpose of this utility model provides a kind of main valve of improved stainless steel four-way change-over valve with regard to being the deficiency that exists at prior art, it has, and processing technology is simple, the characteristics of good product quality.
For achieving the above object, the main valve of stainless steel four-way change-over valve of the present utility model includes main valve body, main valve seat, D adapter, E adapter, S adapter, C adapter, D takes over and is welded on the main valve body upper end, described main valve body lower end is concaved with embedding groove, main valve seat is installed in the embedding groove, and be tightly connected by welding manner and main valve body, E takes over, S takes over, C takes over then be opened in main valve seat on mounting hole cooperate, and be tightly connected by welding manner and main valve seat.
Preferred as technique scheme, the embedding groove on described main valve seat and the main valve body is a drive fit.
Preferred as technique scheme forms the boss arc surface that is used to inlay installation on the main arc surface of described main valve seat, the arc diameter of main arc surface is identical with the internal diameter of main valve body, and the arc diameter of boss arc surface is identical with the external diameter of main valve body.
The beneficial effects of the utility model are: be concaved with the embedding groove that is used to install main valve seat on its main valve body, not only can simplify the processing technology of main valve body, can also make the weld assembly of main valve realize that the unification of material connects, promptly carry out the welding of main valve body and main valve seat earlier, carry out the welding of main valve seat and copper connecting tube again, can enlarge the scope of selecting for use of scolder like this.And adopt the welding one by one of part, and not only can make the variation of selecting for use of welding method, can also make the welding temperature of copper connecting tube and main valve seat be controlled at reduced levels, thereby avoid the appearance of problems such as the copper connecting tube grain size is thick.Simultaneously, because main valve body has been cancelled original E, S, C takes over the hole, the adapter hole that E, S, C adapter are not had when assembling because of main valve body and main valve seat processes the bad situation generation that can't normally pack into that causes taking over.
