Photovoltaic motor-driven inclined bellow welding type stop valve

Abstract

The invention discloses a photovoltaic motor-driven inclined bellow welding type stop valve, and relates to a stop valve, which is characterized in that: an inclined welding type valve body is overlaid with a Co base hard alloy seal ring; a titanizing austenite stainless steel bellow device is movably and mechanically connected between the lower part of a valve rod and the upper part of a valve flap; gaskets are embedded into convex-concave positions of the inclined welding type valve body contacting with a valve cover, and the valve cover are mechanically connected with the inclined welding type valve body through bolts, spring gaskets and nuts; the top of a motor is provided with a silicon solar panel; the silicon solar panel, the top rack of the motor and the top of the motor are mechanically connected; the electric-energy output end of the silicon solar panel is electrically connected with the two ends of a storage battery device; the electric-energy output end of a storage battery is electrically connected with a voltmeter and an ammeter; and the storage battery is electrically connected with an electric control device. The stop valve is applicable to pipelines of the oil industry, the chemical industry, the pharmaceutical industry, the power industry and the like under various working conditions.

Description

Technical field: [0001] The invention relates to a cut-off valve, in particular to a photovoltaic electric driven oblique bellows welded 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, and the welded globe valve is only suitable for fully opening and fully 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...

Problems solved by technology

[0003] In order to solve the defect that the large-diameter valve is far away from the power supply line in the prior art, and it is very cumbersome for workers to control it, and to solve the technical problem that the globe valve must apply pressure to the disc when the valve is closed to force the sealing surface not to leak, the invention provides a Photovoltaic Electric Drive Inclined Bellows Welded Globe Valve
