Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following description, together with the drawings of the present invention, clearly and completely describes the technical solution of the present invention, and based on the embodiments in the present application, other similar embodiments obtained by those skilled in the art without creative efforts shall all belong to the protection scope of the present application. In addition, directional terms such as "upper", "lower", "left", "right", etc. in the following embodiments are directions with reference to the drawings only, and thus, the directional terms are used for illustration and not for limitation of the present invention.
As shown in fig. 1, the utility model provides a pneumatic angle seat valve, it includes pneumatic head, valve body and is used for connecting the sealing 300 of pneumatic head and valve body, the valve body is provided with the case between inflow channel and outflow channel including the inflow channel and the outflow channel of intercommunication, the case control inflow channel and outflow channel's intercommunication, when the case blocks inflow channel and outflow channel, the fluid contacts with the case top surface in the inflow channel.
Specifically, the sealing portion 300 includes a sealing ring 310, a sealing groove corresponding to the sealing ring 310, and a sealing cavity for connecting the pneumatic head and the valve body, the valve body further includes a cut-off port 230, the valve element is disposed inside the cut-off port 230, a valve rod 232 is disposed at the upper end of the valve element 231, and the valve rod 232 penetrates through the sealing cavity to be connected with the pneumatic head.
Specifically, the pneumatic head includes the casing and sets up at the inside piston 110 of casing, the inside air chamber 120 that is provided with of casing is provided with the air inlet 130 that links to each other with air chamber 120 on the casing, advances the exhaust through air inlet 130, realizes having guaranteed that the valve body can accurately open and close to the promotion of piston 110, ensures can be timely effectual control fluid the circulation with end.
Specifically, a valve rod hole for the valve rod 232 to pass through is formed in the piston 110, and limiting grooves for limiting the valve rod 232 to move synchronously with the piston 110 are formed in two sides of the valve rod hole.
