Problems solved by technology

[0002] Most of the existing angle valves have a point contact seal between the valve core and the valve seat, such as a pneumatic angle valve disclosed in a Chinese patent with the patent number "200820145470". With such a sealing structure, the sealing performance will decrease after a long time, and leakage will easily occur. Phenomenon; there are also inlet and outlet connections connected by screws, which is not only troublesome to disassemble, but also poor in sealing

Abstract

The invention relates to an angle valve which comprises an actuating mechanism, a valve body, a valve cover, a valve core and a valve seat, wherein the valve cover, the valve core and the valve seat are fixed on the valve body; the valve body is provided with an inlet and an outlet; an angle of 90 degrees is formed between the inlet and the outlet; the valve core is connected with the valve rod penetrating through the valve cover; and the valve seat is fixed in the valve body. The angle valve is characterized in that the valve core is conical; a chamfer is arranged at the matched part of the valve seat and the valve core; and an internal thread is arranged at the connected part of the inlet and the outlet. The angle valve has an excellent sealing performance and is easy to dismount and mount with an external pipeline.

Description

technical field [0001] The invention relates to an angle valve. Background technique [0002] Most of the existing angle valves have a point contact seal between the valve core and the valve seat, such as a pneumatic angle valve disclosed in a Chinese patent with the patent number "200820145470". With such a sealing structure, the sealing performance will decrease after a long time, and leakage will easily occur. Phenomenon; there are also inlet and outlet connections connected by screws, which is not only troublesome to disassemble, but also poorly sealed. Contents of the invention [0003] The purpose of the present invention is to provide an angle valve with excellent sealing performance and convenient connection. [0004] The technical scheme adopted in the present invention is: [0005] An angle valve, including an actuator, a valve body, a valve cover fixed on the valve body, a valve core and a valve seat, the valve body is provided with an inlet and an outlet, the...
