On the described movable inner cover bottom periphery U-shaped convex edge is set, the U-shaped groove of arc length greater than U-shaped convex edge arc length is set on the spool end face periphery, in embedding of movable inner cover convex edge and the spool end face groove, between movable inner cover and spool, form deformable cavities.
Fixing outer the covering of described main valve body has two pilot valve capillary tube jacks, and two pilot valve capillary tube liquid outlet ends are separately fixed on two perpendicular end surface of movable inner cover U-shaped convex edge.
The utility model compared with prior art has many advantages and good effect:
1, the utility model is realized commutation by the taper valve core rotation, has replaced the translation of existing four-way change-over valve inner slider piece and has carried out changement.Simple in structure, compact, the valve body component significantly reduce, and have saved complicated processing technologys such as welding, and processing and assembling is simple, and manufacturing efficiency improves, and cost reduces.
2, because taper valve core self seal performance is good, be difficult for leaking, and self repair function arranged, its service time, long more sealability was good more, did not have other movable part that has sealing material, long service life.
3, spool operating movement distance is little, only turns an angle and can play the commutation effect, and the power of valve body is big more, can embody the little advantage of its volume more, and is highly sensitive, good reliability.
4, more less or close because of valve volume of the present utility model than existing valve volume, need not change the air conditioner internal structure and all can install and use easily, be convenient to air conditioner and apply.
5, valve body structure of the present utility model is the developing direction of various from now on liquid four-way change-over valves, and application surface is extensive, belongs to the product of update.
6, China's air conditioner output in 2000 is 1,800 ten thousand, and calendar year 2001 is estimated as 2,000 ten thousand, if press 15 yuan/only calculating of every price difference at present, 300,000,000 yuan of annual saving.This brings bigger economic benefit to society, and will bring bigger interests to manufacturer and user.
