Problems solved by technology

The small one must be more than 600mm, so the volume is large;
[0004] 2. The pneumatic film discharge valve is heavy;
[0006] 4. If there are sand and hard objects between the valve core and the valve seat, during the closing process of the valve, traces will be pressed on the seal between the valve core and the valve seat, which will damage the seal and make it impossible to seal. The medium in the container leaks and cannot be closed tightly, causing accidents, etc.

Abstract

The invention discloses a pneumatic discharging ball valve, which comprises a discharging ball valve, wherein the valve rod of the discharging ball valve is connected with a linkage mechanism; the other end of the linkage mechanism is connected with a straight travel cylinder; and the straight travel cylinder drives the linkage mechanism to operate so as to control the opening and closing of the discharging ball valve. The pneumatic discharging ball valve has small size, a short valve body and high closing or switch-off capacity, does not leak, and is opened and closed sensitively.

Description

technical field [0001] The invention relates to a pneumatic discharging ball valve. Background technique [0002] At present, most of the control valves used at the bottom of chemical containers or reaction kettles are pneumatic film discharge valves. Through the control of the pneumatic film discharge valve, the medium in the container is controlled. There are several technical aspects of the pneumatic film discharge valve. The problem: [0003] 1. Pneumatic film discharge valve is large in size. When the valve diameter is 250mm, its length is more than 1000mm. The small one must be more than 600mm, so the volume is large; [0004] 2. The pneumatic film discharge valve is heavy; [0005] 3. The pneumatic film discharge valve is a hard seal design, which requires high manufacturing precision, and the valve seat and valve core will wear and cause leakage; [0006] 4. If there are sand and hard objects between the valve core and the valve seat, during the closing process o...
