Abstract

Provided are a stop valve ( 100 ) and an air conditioner having the same. The stop valve ( 100 ) includes: a valve seat ( 1 ) defining a valve chamber ( 11 ) and a fitting chamber ( 12 ) in communication with the valve chamber ( 11 ), in which the fitting chamber ( 12 ) is located at a first end face of the valve chamber ( 11 ) and the valve chamber ( 11 ) is provided with two ports ( 112 ) in communication with the valve chamber ( 11 ); a lantern ring ( 2 ) fitted in one of the two ports ( 112 ); a valve disc ( 3 ) including a fitting part ( 31 ) and a stopping part ( 32 ) disposed to the fitting part ( 31 ), in which the fitting part ( 31 ) is threadedly fitted with the fitting chamber ( 12 ), the stopping part ( 32 ) is located in the valve chamber ( 11 ); and an elastic sealing member ( 4 ).

First claim

1 . A stop valve, comprising:
a valve seat defining a valve chamber and a fitting chamber in communication with the valve chamber, wherein the fitting chamber is located at a first end face of the valve chamber and the valve chamber is provided with two ports in communication with the valve chamber; a lantern ring fitted in one of the two ports; a valve disc comprising a fitting part and a stopping part disposed to the fitting part, wherein the fitting part is threadedly fitted with the fitting chamber, the stopping part is located in the valve chamber and threadedly fitted with the valve chamber, and the stopping part is configured to touch the first end face or the lantern ring to communicate or block the two ports; and an elastic sealing member disposed at an end face of the stopping part facing the lantern ring and configured to touch an end face of the lantern ring to block a communication of the two ports.

2 . The stop valve according to claim 1 , further comprising a fastening washer and a fixing member, wherein the fixing member passes through the fastening washer and the elastic sealing member successively to be fixed to the valve disc.

3 . The stop valve according to claim 2 , wherein the elastic sealing member is provided with a groove for receiving the fastening washer, and an end face of the elastic sealing member facing the lantern ring is flush with an end face of the fastening washer.

4 . The stop valve according to claim 3 , wherein a free end of the fixing member is flush with the fastening washer.

5 . The stop valve according to claim 1 , wherein the stopping part is provided with a receiving groove, a central part of the elastic sealing member is received in the receiving groove, and a rest part thereof is located on the end face of the stopping part for touching the lantern ring.

6 . The stop valve according to claim 1 , further comprising an annular sealing gasket embedded in an outer peripheral wall of the fitting part.

7 . The stop valve according to claim 1 , wherein the elastic sealing member is fitted with the end face of the lantern ring in a non-inclined plane.

8 . The stop valve according to claim 1 , wherein the elastic sealing member is fitted with the end face of the lantern ring in an inclined plane.

9 . The stop valve according to claim 1 , wherein the elastic sealing member is a rubber member or a plastic member.

10 . An air conditioner, comprising a stop valve, wherein the stop valve comprises:
a valve seat defining a valve chamber and a fitting chamber in communication with the valve chamber, wherein the fitting chamber is located at a first end face of the valve chamber and the valve chamber is provided with two ports in communication with the valve chamber; a lantern ring fitted in one of the two ports; a valve disc comprising a fitting part and a stopping part disposed to the fitting part, wherein the fitting part is threadedly fitted with the fitting chamber, the stopping part is located in the valve chamber and threadedly fitted with the valve chamber, and the stopping part is configured to touch the first end face or the lantern ring to communicate or block the two ports; and an elastic sealing member disposed at an end face of the stopping part facing the lantern ring and configured to touch an end face of the lantern ring to block a communication of the two ports.

11 . The air conditioner according to claim 10 , further comprising a fastening washer and a fixing member, wherein the fixing member passes through the fastening washer and the elastic sealing member successively to be fixed to the valve disc.

12 . The air conditioner according to claim 11 , wherein the elastic sealing member is provided with a groove for receiving the fastening washer, and an end face of the elastic sealing member facing the lantern ring is flush with an end face of the fastening washer.

13 . The air conditioner according to claim 12 , wherein a free end of the fixing member is flush with the fastening washer.

14 . The air conditioner according to claim 10 , wherein the stopping part is provided with a receiving groove, a central part of the elastic sealing member is received in the receiving groove, and a rest part thereof is located on the end face of the stopping part for touching the lantern ring.

15 . The air conditioner according to claim 10 , further comprising an annular sealing gasket embedded in an outer peripheral wall of the fitting part.

16 . The air conditioner according to claim 10 , wherein the elastic sealing member is fitted with the end face of the lantern ring in a non-inclined plane.

17 . The air conditioner according to claim 10 , wherein the elastic sealing member is fitted with the end face of the lantern ring in an inclined plane.

18 . The air conditioner according to claim 10 , wherein the elastic sealing member is a rubber member or a plastic member.
