Abstract

The invention belongs to the technical field of valve equipment, and in particular, relates to a right-angled manual valve based on a pilot structure. The right-angled manual valve comprises a valve body, wherein a valve cover is fixedly mounted above the valve body; a support frame is fixedly mounted above the valve cover; the internal of the support frame is in threaded connection with a pilot rod; a rotating handle is mounted at the upper end of the pilot rod through a thread; a locking nut is in threaded connection between the pilot rod and the rotating handle; the pilot rod and the valve core are matched and provided with a pressure plate; the other end of the pilot rod is in threaded connection with a pilot valve core; the external of the pilot valve core is matched and provided with a valve core closing plug; the external of the valve core closing plug is in threaded connection with a valve core; a feed port is formed in one side, far from the valve core, of the valve body; and a discharge port is formed below the valve core. The valve adopts the pilot structure, can realize quick opening, is low in opening torque, and largely prolongs the service life.

Description

technical field [0001] The patent of the invention belongs to the technical field of valve equipment, and in particular relates to a right-angle manual valve based on a pilot structure. Background technique [0002] Valves are used in fluid systems to control the direction of fluid, pressure 1. The flow device is a device that makes the medium (liquid, gas, powder) in the piping and equipment flow or stops and can control its flow. The control of the valve can adopt a variety of transmission methods, such as manual, electric, hydraulic, pneumatic, turbine, electromagnetic, electro-hydraulic, electro-hydraulic, gas-hydraulic, spur gear, bevel gear drive, etc.; can be driven by pressure, temperature Under the action of sensing signals in other forms, it acts according to predetermined requirements, or simply opens or closes without relying on sensing signals. The valve relies on driving or automatic mechanism to make the opening and closing parts lift, slide, swing or rotate....
