Abstract
The utility model provides a main valve base of an electromagnetic four-way reversing valve. The main valve base comprises a valve base body and a plurality of welding holes formed on the valve base body and used for welding connecting pipes, wherein linear grooves are arranged on the two sides of the welding holes on the valve base body. The main valve base of the electromagnetic four-way reversing valve has the advantages of simple structure and low manufacturing cost.
Description
Technical field
The utility model relates to the electromagnetism four-way change-over valve that uses in the air conditioner refrigerating industry, is specifically related to a kind of electromagnetism main valve of four-way reversing valve seat.
Background technique
Existing electromagnetism four-way change-over valve is the important devices of heat pump type air conditioner, is applicable to central authorities, split, window air conditioner etc.The action of existing electromagnetism four-way change-over valve is under the height pressure reduction pilot valve drive formerly that utilizes in the system, thereby realizes that conversion realizes the conversion of the refrigerant flow direction.Existing electromagnetism main valve of four-way reversing valve seat mainly cooperates near closed hollow ring to change the hot and cold commutation function that refrigerant flow direction is realized air-conditioning with slide block.The structure of existing electromagnetism main valve of four-way reversing valve seat is referring to shown in Figure 1, existing electromagnetism main valve of four-way reversing valve seat comprises valve seat body 1 and is located on the valve seat body 1 three and cooperates the welding holes 2 that weld with taking over, each welding hole 2 all is the through hole with a step, the top of described valve seat body 1 is face of weld, the bottom is a sealing surface, the slide block of electromagnetism four-way change-over valve contacts with sealing surface, and described slide block and sealing surface relative movement realize different connections of taking over.The main valve seat of existing four-way valve is semicircle " D " shape, causes the main valve seat raw-material weight heavy, the cost height.Referenced patent CN201074686Y is mentioned to a kind of electromagnetism main valve of four-way reversing valve seat, comprises and take over cooperating the welding hole that welds, and described welding hole is the through hole with a step surface; The arc surface that described welding hole has than a side place of macropore is a face of weld; The another side relative with face of weld is sealing surface; Between described face of weld and described sealing surface, a step surface is set.Step surface can stop scolder and flow to sealing surface, thus the generation of fluid welding phenomenon in effectively avoiding.This structure with respect to existing " D " thus the four-way valve of shape can reduce material to reduce cost, but complex structure causes the manufacturing process complexity, whole manufacture cost height.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of electromagnetism main valve of four-way reversing valve seat, and is simple in structure, low cost of manufacture.
For solving above-mentioned prior art problems, the utility model adopts following scheme: a kind of electromagnetism main valve of four-way reversing valve seat, comprise valve seat body, be located at the some welding holes that cooperate welding with adapter on the valve seat body, the both sides that are positioned at welding hole on the described valve seat body are provided with straight-line groove.
As preferably, described straight-line groove is the center bilateral symmetry with the welding hole line of centres.
As preferably, the cross section of described straight-line groove is right angle type or arc.Processing technology is simple.
As preferably, the diapire that is positioned at straight-line groove on the described valve seat body is provided with baffle plate.When welding is taken over, overflow and flow to sealing surface along face of weld in the scolder shop, and the generation of fluid welding phenomenon in causing adopts straight-line groove to cooperate with baffle plate, the generation of weldering flow phenomenon in can effectively avoiding.
As preferably, described baffle plate and valve seat body are structure as a whole.Only need to vacate the directly grooving of part back in edge, manufacturing process is simple.
Beneficial effect:
The utility model adopts technique scheme that a kind of electromagnetism main valve of four-way reversing valve seat is provided, and the both sides that are positioned at welding hole on valve seat body are provided with straight-line groove, has reduced manufacture cost by reducing main valve seat raw material consumption, and simple in structure.
