Embodiment 1

[0022] refer to figure 1 , figure 2 It is an embodiment of a shut-off valve for air conditioners and an assembly method thereof of the present invention. A shut-off valve for air conditioners includes a valve body 2 provided with a valve core installation hole 1, and a valve core 3 is installed in the valve core installation hole 1. The outer eaves of the top of the valve core 3 are provided with an outer conical surface 4, and the valve body 2 is provided with a stainless steel inner sleeve 5 for fixing the position of the valve core 3, and a stainless steel inner sleeve 5 is fixed between the stainless steel inner sleeve 5 and the valve body 2. The outer sleeve 6, the top of the stainless steel inner sleeve 5 is provided with a sealing body 7 that extends to the center of the stainless steel inner sleeve 5 and forms a line seal with the outer conical surface 4 on the top of the valve core 3, and the sealing body 7 is connected to the stainless steel inner sleeve The protru...

Embodiment 2

[0029] Such as image 3 As shown, the difference from the first embodiment is that the sealing body 7 is a metal ring, and the sealing body 7 is fixed on the inner wall of the top of the stainless steel inner sleeve 5 .

[0030] The difference between the assembly method and the first embodiment is that in step A, the top of the stainless steel inner sleeve 5 is welded to the stainless steel annular sealing body 7 by argon arc welding or laser welding.

[0031] In the above two embodiments, the upper part of the valve body 2 is replaced by two stainless steel sleeves made of stainless steel. In order to avoid the high temperature of brass and stainless steel welding from affecting the sealing ring on the valve core 3, the stainless steel outer sleeve 6 Brazed with the brass valve body 2, after the valve core 3 is installed, the stainless steel outer sleeve 6 and the stainless steel inner sleeve 5 are fixed by argon arc welding, although there is a high temperature locally, sin...

Abstract

The invention discloses a stop valve for an air conditioner and an assembly method of the stop valve. The stop valve comprises a valve body with a valve element mounting hole, wherein a valve element is mounted in the valve element mounting hole; an external circular conical surface is arranged on the outer edge of the top of the valve element; a stainless steel inner sleeve for fixing the valve element is arranged on the valve body; a stainless steel outer sleeve is fixed between the stainless steel inner sleeve and the valve body; a sealing body is arranged at the top of the stainless steel inner sleeve and extends to the center of the stainless steel inner sleeve to form line sealing with the outer conical surface at the top of the valve element. The assembly method comprises the following steps: arranging the sealing body at the top of the stainless steel inner sleeve, welding the stainless steel outer sleeve with a valve seat through brass soldering, placing the valve element in the valve seat, and fixing the stainless steel outer sleeve with the stainless steel inner sleeve through argon arc welding. The stop valve disclosed by the invention has the advantages of effectively lowering the material cost of the valve body, not influencing the sealing ring on the valve element in the assembling process, meanwhile forming good sealing by virtue of the line contact between the sealing body and the outer conical surface at the top of the valve element, so as to prevent leakage.

Description

technical field [0001] The invention relates to a shut-off valve for an air conditioner and an assembly method thereof. Background technique [0002] At present, the maintenance stop valve for air conditioners includes a valve body. A valve chamber with threads is arranged in the valve body. A vertical spool mounting hole with an opening upward and communicating with the valve chamber is arranged on the valve body. Connect to control the opening and closing of the passage in the valve body. The installation hole of the valve core is closed by adding a cap. The cap is provided with a ring-shaped sealing protrusion for sealing. Now the valve core and the valve core installation hole rely on an O-ring on the valve core. To achieve sealing, but after a long time of operation, there is not a small amount of leakage, and the globe valve body and cap are made of brass, and the material cost is relatively high. Contents of the invention [0003] The object of the present inventio...
