Or close up in described sleeve top, when stop valve is opened, the closing in top on sleeve top is pressed in described spool outer conical surface one.
Preferably, described sleeve diameter is greater than the maximum outside diameter of spool; Sleeve and valve body first weld, and reinstall spool, solve first to pack the spool O type circle that welded sleeve and valve body may cause again into and melt the problem of poor sealing.
Preferably, described end cap comprises and is close to the sealed department of sleeve lining and the positioning part contacting with sleeve top end; Fix the relative position of end cap on sleeve by positioning part, preventing that sealed department is subjected to displacement affects sealing effect.
Preferably, outside, described end cap bottom eaves offers outer conical surface two; While better making end cap contact with outer conical surface one, form line contact sealing.
Optionally, described end cap bottom inner edge eaves has conical surface; The middle part that can make the more close outer conical surface one in position of line contact sealing, forms good sealing.
Preferably, the positioning part of described end cap and sleeve top end are welded and fixed; End cap and sleeve can closely be linked together.
Preferably, described sleeve adopts stainless steel material, and described end cap adopts stainless steel; Guarantee good sealability.
Preferably, described sleeve diameter is greater than the maximum outside diameter of the screw thread of spool; Sleeve can adopt thin-wall part without screw thread.
Compared with prior art, the utility model has the advantages that: sleeve and valve body adopt split-type design, sleeve adopts the materials such as stainless steel to make again and fixes by mode and the valve body of welding, effectively reduce fabricating cost, in the time that spool is outwarded winding, the outer conical surface one at spool top contacts with end cap bottom line and forms the second sealing simultaneously, prevents from revealing occurring in the time that seal with O ring lost efficacy.

Embodiment
Consult Fig. 1, Fig. 2 is the embodiment of a kind of break valve for air conditioner of the utility model, a kind of break valve for air conditioner, comprise the valve body 1 that is provided with valve chamber 2 and the spool 3 that screws in valve chamber 2, the top end of described spool 3 have along central axis straight down revolve hole 4, revolving hole uses for rotary spool, it can be inner hexagonal hole, elliptical aperture, the various shapes such as square hole, on the valve body 1 of described valve chamber 2 entry ends, be fixed with steel or the aluminum sleeve 5 of being convenient to the isometrical hollow cylindrical that spool 3 installs, the sleeve of so-called isometrical hollow cylindrical is hollow wall no choke or boss, between the upper portion side wall of described spool 3 and sleeve 5 madial walls, be provided with seal ring 6, described sleeve 5 tops are provided with along sleeve 5 walls stretches into the ring-type end cap 7 in sleeve 5, described spool 3 outside, top eaves offer outer conical surface 1, in the time that spool 3 is outwarded winding, outer conical surface 1 contacts with end cap 7 bottom line, described sleeve diameter is greater than the maximum outside diameter of spool, described revolving on the relative end cap in hole 47 has for instrument and stretches into the through hole 9 that revolves hole 4, the diameter of through hole 9 is greater than the diameter of spool 3 end faces, as shown in Figure 3, described end cap 7 comprises is close to the sealed department 12 of sleeve 5 inwalls and the positioning part 13 contacting with sleeve 5 top ends, on described end cap 7, cover has the block 14 that through hole 9 is sealed, the upper portion side wall of described spool 3 has circular groove 15, described seal ring 6 is arranged in circular groove 15 for O shape is enclosed.
Sleeve 5 is fixed by the mode of welding with valve body 1, and sleeve 5 and end cap 7 all adopt stainless steel, and block 14 adopts plastic material, effectively reduces costs.
