The valve seat is installed at the opening of the valve body and connected with the valve body. body welding. The nozzle part is inserted into the valve seat and welded to the valve seat to achieve a fixed connection between the valve body, the valve seat and the nozzle. However, the stop valve structure in the related art has many welding processes and a large amount of solder, which increases the cost of the stop valve.
为了解决上述问题，请参阅图1，本申请提供一种截止阀100，该截止阀100包括阀体10、阀座20、第一接管30及第二接管40。In order to solve the above problem, please refer to Figure 1. This application provides a stop valve 100. The stop valve 100 includes a valve body 10, a valve seat 20, a first pipe 30 and a second pipe 40.
阀体10开设有第一开口11及第二开口12，阀座20至少部分经第一开口11设于阀体10内，第一接管30套设于至少部分阀座20，且第一接管30位于阀体10与阀座20之间，第一开口11通过第一接管30实现与外部空调管路的连通。第二接管40部分***第二开口12内，并与阀体10焊接固定，第二开口12通过第二接管40实现与外部空调管路的连通。当截止阀100开启时，介质可通过第一接管30进入阀体10内，并通过第二接管40流出。或者，介质通过第二接管40进入阀体10内，并通过第一接管30流出。The valve body 10 is provided with a first opening 11 and a second opening 12. The valve seat 20 is at least partially disposed in the valve body 10 through the first opening 11. The first connecting pipe 30 is sleeved on at least part of the valve seat 20, and the first connecting pipe 30 Located between the valve body 10 and the valve seat 20 , the first opening 11 is connected to the external air conditioning pipeline through the first connecting pipe 30 . The second pipe 40 is partially inserted into the second opening 12 and is welded and fixed with the valve body 10 . The second opening 12 is connected to the external air conditioning pipeline through the second pipe 40 . When the stop valve 100 is opened, the medium can enter the valve body 10 through the first pipe 30 and flow out through the second pipe 40 . Alternatively, the medium enters the valve body 10 through the second pipe 40 and flows out through the first pipe 30 .
并且，阀体10内侧壁、阀座20外侧壁以及第一接管30之间围成有焊料槽50，阀体10、阀座20及第一接管30通过焊料槽50内的焊料相互焊接。需要说明的是，焊料槽50内的焊料通常情况下为焊环。在本实施例中，在焊料槽50内放置一个焊环，该焊环融化实现阀体10、阀座20及第一接管30之间的相互连接。Furthermore, a solder groove 50 is enclosed between the inner wall of the valve body 10 , the outer wall of the valve seat 20 and the first pipe 30 .

The valve seat 20 of the present application partially extends into the first pipe 30, thereby reducing the radial size of the valve seat 20 compared with the valve seats in the related art and saving materials. In addition, the valve body 10 of the present application is sleeved on the valve seat 20, and the size of the valve body 10 is also reduced, thereby further saving materials and reducing the overall manufacturing and processing cost of the stop valve 100.
