Problems solved by technology

Although the applicant's 01121587.9 "Air Conditioner Shut-Off Valve Group" has solved this problem well, it still has the disadvantage of insufficient airtightness because the valve core is floating.

Embodiment Construction

[0009] as attached figure 1 and 2 As shown, the one-piece spool air conditioner cut-off valve group consists of a low-pressure cut-off valve and a high-pressure cut-off valve. The low-pressure stop valve and the high-pressure stop valve include a valve body 3 and a valve core 6 and a valve sleeve seat 2 installed therein, a sealing cap 7 installed outside the valve body 3, and a connecting pipe 1 fixed on the valve sleeve seat 2. The valve core 6 has a front sealing surface 4 and a rear sealing surface 5, and the inner cavity of the valve body 3 has a structure corresponding to the rear sealing surface 5. The spool 6 is integrated. The valve sleeve seat 2 adopts the method of post-loading to install.

[0010] The valve body 3 of the low-pressure stop valve has four inner cavities, wherein the left and right two inner cavities are coaxial, which is the same as the prior art; and the upper and lower inner cavities are different axes, which is different from the prior art. th...

Abstract

The present invention relates to common part for air conditioner and is especially one device for preventing condensated liquid from being exhausted. The present invention solves the technological problem of providing one stop valve combination with integrated valve core and thus high air tightness and long service life for air conditioner. The stop valve combination consists of high pressure stop valve and low pressure stop valve, and each of the high pressure stop valve and low pressure stop valve includes valve body, integral valve core with front and back sealing planes, valve seat, sealing cap and adaptor. The present invention is suitable for use in split air conditioner, especially one with 5 P and below power, central air conditioner and automobile air conditioner.

Description

technical field [0001] One-piece spool air conditioner shut-off valve group relates to general parts for air conditioning, especially the device for preventing condensate from being drained away. Background technique [0002] As we all know, the compressor of the air conditioner has two shut-off valves: the exhaust shut-off valve (low pressure valve) and the suction shut-off valve (high pressure valve). The existing device for preventing the draining of condensate, the stop valve, has only one sealing surface for the spool, that is, the front sealing surface. This sealing surface acts as a seal when the globe valve is closed. When the globe valve works, it is sealed by the O-ring on the valve core. In the case of long-term work, the O-ring, especially the O-ring in the high-pressure stop valve, is prone to aging, causing the refrigerant to leak slowly. This is a technical problem that has not been thoroughly solved for a long time. Although the a...
