Abstract
The utility model relates to a fast opening mud valve, which comprises a valve body, a valve cap for a piston cylinder, a piston, a guide body for a baffle plate, a spring, a valve core, a guide ring, a sealing ring, and a valve position signal feedback device, and is characterized in that the valve seat of the fast opening mud valve is located outside the outlet of the valve body, and a valve flap is located outside the outlet of the valve. A driving medium is introduced into the upper chamber of the piston cylinder to generate, by the piston, a force which compresses the spring and pushes apart the valve flap and the valve seat on the valve core, thereby opening the valve. T the driving medium in the upper chamber of the piston cylinder is closed so that the active force on the valve flap by the flow and the mechanical resistance are overcome by the elastic force of the spring and the valve flap is further pushed towards the valve seat until the valve flap contacts with the seal ring on the valve seat, thereby closing the valve. The valve position signal feedback device is installed on the valve cap for a piston cylinder.
Description
Technical field
The utility model relates to a kind of quick-opening mud valve, belongs to control stop valve class.
Background technique
The flap of common common quick-opening mud valve all is arranged in the valve body, and when the silt sand content was big especially in the fluid, often becoming silted up in the body cavity was collecting a large amount of silts, even silt abrim.Silt because silt usually causes valve opening very slow to the retardation of flap, needs tens of minutes ability all to open for a long time sometimes, and is stuck in and is difficult in the silt move often being full of under the situation of silt flap, often causes valve not open.Simultaneously, conventional common quick-opening mud valve does not all have the valve position feedback signal, can not reflect the valve position present position during remote centralized control.
Summary of the invention
The purpose of this utility model is to overcome the existing existing above-mentioned defective of common quick-opening mud valve, provide a kind of when silt is full of body cavity reliable open and close valve and the quick-opening mud valve of valve position feedback signal is provided still.
