Abstract

The invention provides a hydraulic transmission clamped and sleeved connection type corrugated pipe stop valve and relates to a hydraulic transmission stop valve. The hydraulic transmission clamped and sleeved connection type corrugated pipe stop valve comprises a clamped and sleeved connection type valve body, wherein a Co-based hard alloy sealing ring is resurfaced and welded on the valve body. A titanizing austenitic stainless steel dual-corrugated-pipe device is movably and mechanically connected below a valve rod, a lower head of the valve rod is movably and mechanically connected with a valve clack, and a hydraulic transmission head mandrel is rotated to enable a lifting rod of the valve rod to drive the titanizing austenitic stainless steel dual-corrugated-pipe device to lift by a hydraulic transmission head mandrel sleeve. The dual firm and durable corrugated pipes are convenient to disassemble, and an exterior connection pipe and the sealing ring fasten a nut compaction ring by a clamping and sleeving nut so as to enable pipelines to be connected. The clamped and sleeved connection is convenient to disassemble, Co-based hard alloy resurfaced and welded on a sealing face and titanizing austenitic stainless steel of the corrugated pipes have good properties of abrasion resistance, erosion resistance and friction resistance and long service life, and the hydraulic transmission clamped and sleeved connection type corrugated pipe stop valve is suitable for switching off or switching on pipeline media on engineering pipelines with various working conditions in an interior connection pipeline of the clamping and sleeving nut.

Description

Technical field: [0001] The invention relates to a hydraulic transmission cut-off valve. Background technique: [0002] At present, in the known stop valve, the opening and closing part of the stop valve is a plug-shaped valve disc, the sealing surface is a plane or a conical surface, and the valve disc moves linearly along the center line of the fluid. The movement type of the valve stem has a lifting rod type. The stop valve is only suitable for full opening and full closing, and adjustment and throttling are not allowed. It is a forced sealing valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface not to leak. When the medium enters the valve from the bottom of the disc, the resistance that the operating force needs to overcome is the friction between the valve stem and the packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so the valve s...
