A multi-flow hole type safety shut-off plate valve

Abstract

The invention relates to a flat valve, in particular to a multi-hole safety shut-off flat valve. The upper end of the housing I is fixedly connected to the mounting ring, and the mounting ring is rotated to connect the buckle cover. The lower end of the buckle cover is fixedly connected to the plunger. The holes are arranged in the middle of the center column from front to back. The center column is uniformly connected with four dials in the circumferential direction. A bypass hole is provided at the end, and the bypass hole communicates with the adjacent middle groove. The plate body I is slidably connected to the middle groove, and the upper side of the plate body I is provided with a communication port I. The through holes can be connected or staggered, the upper end of the plate body I is fixedly connected to the connecting block, the screw I is rotatably connected in the connecting block, the screw I passes through the plug and is screwed to the buckle cover, and the shell II is fixedly connected to the lower end of the shell I. According to the adjustment, the effect of single-entry single-row, single-entry double-row or single-entry three-row can be realized.

Description

Technical field [0001] The present invention relates to a tablet valve, more specifically a multi-flow well safety truncated plate valve. Background technique [0002] For example, the disconnectures are CN21179083U, which is resistant to corrosion-resistant oil-resistant oil-resistant, including a flat valve body, and a control assembly disposed inside the flat valve main body. The two ends of the flat valve body pass through the flange connection hole and bolts respectively with the oil pipe and out, respectively. Tube Unicom; the control assembly is mounted inside the flat valve body in the longitudinal direction, the control assembly is opened, and the bottom is fixed to the lower end cap, the top of the control assembly extends through the upper end cover exterior And set up a turntable. The utility model uses seals and coatings, leak-proof, anti-corrosion and wear resistance to enhance the service life of the device; uses a control valve stem with open apertures, control th...

AI Technical Summary

Problems solved by technology

The utility model adopts seals and coatings, which are leak-proof, anti-corrosion and wear-resistant, and enhances the service life of the device; it adopts a control valve stem with a through hole, a control baffle plate and a control spring to control the communication and connection inside the main body of the flat valve. Partition; the combination of slider and L-shaped chute enables the control valve stem to be stuck at any position within the range of 0° to 90° clockwise rotation, thereby adjusting the flow rate inside the main body of the flat valve, but the flat valve cannot realize multi-flow function
