Description

Technical Field

[0001] The utility model relates to the technical field of angle seat valves, in particular to an angle seat valve. Background Art

[0002] Angle seat valves are divided into pneumatic angle seat valves and manual angle seat valves, which are mainly composed of an actuator, a valve stem connecting sleeve (connecting bracket), a valve stem and a valve body. The valve stem is driven by the actuator mechanism to perform axial linear motion. When the valve stem moves upward, the valve body channel opens, and when the valve stem moves downward, the valve body channel closes, realizing the connection and disconnection of the pipeline. The pneumatic control of the angle valve seat can accurately control the flow of gas and liquid, and can achieve accurate temperature control and dripping requirements. It is mainly used in pharmaceutical, food and beverage, brewing, chemical and other industries.

[0003] The traditional angle seat valve lacks a filtering structure at the medium inlet, resulting in the quality of the medium being unable to guarantee safety in use. The filtering structure is not flexible enough in its detachability, resulting in poor practicality.

[0004] The valve stem passes through the valve cover to drive the valve seal to cooperate with the valve seat in the valve body to realize the conduction and closing of the valve. The sealing ring between the valve cover and the valve body is arranged at the other end of the valve cover relative to the valve seal. The angle seat valve with this structure is prone to produce a narrow retention area between the valve cover and the valve body. The medium is easily retained in the narrow retention area, causing pollution, and it is in urgent need of development. Utility Model Content
