Description
Technical field
The present invention relates to a kind of break valve for air conditioner and its assembly methods.
Background technique
The maintenance shut-off valve of idle call at present includes valve body, and threaded valve chamber is equipped in valve body, on valve body setting opening to
The upper vertical spool mounting hole communicated with valve chamber, spool, which passes through spool mounting hole and is threadedly coupled with valve chamber, carrys out application valve body internal channel
On-off, spool mounting hole are equipped with the ring packing raised line of sealing, present spool and spool by installing nut cap closing, nut cap additional
It is relied between mounting hole on spool and O-ring is set to realize sealing, but after long-play, there are no small leakage rate,
And stop valve body and nut cap are made of brass, and material cost is relatively high.
Summary of the invention
The purpose of the present invention is to provide a kind of break valve for air conditioner and its assembly methods, can effectively solve the problem that existing valve body
Material cost is excessively high, the bad problem of sealing performance.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions: a kind of break valve for air conditioner,
Including the valve body equipped with spool mounting hole, spool is installed, outside eaves offers outer circle at the top of the spool in spool mounting hole
The conical surface, the valve body are equipped with the stainless steel inner sleeve of fixed spool position, fixed between the stainless steel inner sleeve and valve body
There is stainless steel outer sleeve cylinder, is equipped at the top of the stainless steel inner sleeve and stretches to outer conical surface at the top of stainless steel inner sleeve center and spool
Form the seal of linear sealing.
Preferably, the seal is the convex eaves integrally manufactured with stainless steel inner sleeve；Utilize stainless steel inner sleeve itself
Seal is formed to inside edge, it is easy to process.
Optionally, the seal is becket, and the seal is fixed on the inner sidewall at the top of stainless steel inner sleeve；
The becket of extra soldered stainless steel reduces the deformation of stainless steel inner sleeve as seal.
Preferably, the height of the stainless steel outer sleeve cylinder is higher than the height of present position spool and is less than stainless steel inner sleeve
Height；Convenient for welding and positioning.
Preferably, the valve body and stainless steel outer sleeve cylinder are by soldering connection, in the stainless steel outer sleeve cylinder and stainless steel
Sleeve is connected by argon arc welding or Laser Welding；Valve body and stainless steel outer sleeve cylinder can be fixed together by soldering well, argon arc welding
Or Laser Welding can well fix stainless steel outer sleeve cylinder and stainless steel inner sleeve, while will not generate excessively high temperature, protection
Sealing ring is not damaged.
Preferably, the stainless steel inner sleeve is equipped with the closed plastics nut cap of stainless steel inner sleeve；Valve can be protected
Core can reduce cost again.
A kind of assembly method of break valve for air conditioner, successively the following steps are included:
A. seal is set at the top of stainless steel inner sleeve；
B. together with stainless steel outer sleeve cylinder being passed through Welding with valve body；
C. spool is packed into spool mounting hole；
D. stainless steel inner sleeve is covered on spool, stainless steel inner sleeve and stainless steel outer sleeve cylinder pass through argon arc welding or laser
Weldering is fixedly connected.
Preferably, the inside necking in the top of stainless steel inner sleeve is formed into seal in the step A；It is not required to additional material
Material reduces cost and simplifies technique.
Optionally, the top of stainless steel inner sleeve passes through argon arc welding or the ring of Laser Welding soldering stainless steel in the step A
Shape seal；Stainless steel inner sleeve top, which is unlikely to deform, ensures good leakproofness.
Compared with prior art, the invention has the advantages that the top of valve body to be changed to two stainless steels of stainless steel making
Sleeve effectively reduces the material cost of valve body, because brass and stainless steel welded needs use the temperature for being brazed, and being brazed
It is higher, so double stainless steel sleeves are arranged, influence of the temperature to spool upper seal when reducing welding, at the same using seal and
Outer cone brought into linear contact at the top of spool, the good sealing of formation, prevents from leaking.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of break valve for air conditioner of the present invention；
Fig. 2 is the partial enlarged view of embodiment one at A in Fig. 1；
Fig. 3 is the partial enlarged view of embodiment two at A in Fig. 1.
Specific embodiment
Embodiment one:
Refering to fig. 1, Fig. 2 is the embodiment of a kind of break valve for air conditioner of the present invention and its assembly method, a kind of idle call section
Only valve is equipped with spool 3, the 3 top outside eaves of spool including the valve body 2 equipped with spool mounting hole 1 in spool mounting hole 1
Outer conical surface 4 is offered, the valve body 2 is equipped with the stainless steel inner sleeve 5 of 3 position of fixed spool, the stainless steel inner sleeve 5
It is fixed with stainless steel outer sleeve cylinder 6 between valve body 2, is equipped at the top of the stainless steel inner sleeve 5 and stretches to 5 center of stainless steel inner sleeve
The seal 7 of linear sealing is formed with 3 top outer conical surface 4 of spool, the seal 7 is integrally manufactured with stainless steel inner sleeve 5
Convex eaves, the height of the stainless steel outer sleeve cylinder 6 is higher than the height of present position spool 3 and is less than the height of stainless steel inner sleeve 5
By soldering connection, the stainless steel outer sleeve cylinder 6 and stainless steel inner sleeve 5 pass through argon for degree, the valve body and stainless steel outer sleeve cylinder 6
Arc-welding connection, the stainless steel inner sleeve 5 are equipped with the closed plastics nut cap 8 of stainless steel inner sleeve 5.
The assembly method of break valve for air conditioner, successively the following steps are included:
