Description

Valve auxiliary opening and closing device Technical Field The utility model relates to the field of valves, in particular to an auxiliary valve opening and closing device. Background The valve is a pipeline accessory for opening and closing a pipeline, controlling the flow direction, adjusting and controlling parameters (temperature, pressure and flow rate) of a conveying medium. Depending on their function, they can be classified into shutoff valves, check valves, regulating valves, etc. The valve is a control component in the fluid conveying system and has the functions of stopping, adjusting, guiding, preventing backflow, stabilizing pressure, diverting or overflow pressure relief and the like. Valves for fluid control systems, ranging from the simplest shut-off valves to the various valves used in extremely complex automatic control systems, are quite diverse in variety and specification; In the prior art, the butterfly valve mainly depends on the inside butterfly sheet to rotate so as to achieve the effect of opening and closing the pipeline, the rotation of the butterfly sheet is controlled by a worm gear reducer which mainly comprises a worm wheel and a worm, the self-locking performance is realized, the rotation number of the worm is increased, the butterfly valve can be smoothly opened, the butterfly valve needs to be manually rotated for a plurality of circles when being opened and closed, the butterfly valve is troublesome, and the butterfly valve is laborious to rotate. Disclosure of utility model In order to make up the deficiency of the prior art, the worm gear reducer has self-locking property, but the rotation number of the worm is increased to smoothly open the butterfly valve, so that the butterfly valve needs to be manually rotated for a plurality of times when being opened and closed, the problem that the butterfly valve is troublesome and the rotation is laborious is solved. The technical scheme adopted for solving the technical problems is that the valve auxiliary opening and closing device comprises a butterfly valve, wherein an auxiliary mechanism is arranged on the surface of the butterfly valve; The auxiliary mechanism comprises a fixed plate, the bottom of fixed plate is fixedly connected with the top of butterfly valve, one side fixedly connected with second connecting rod of fixed plate, one side rotation of second connecting rod is connected with first gear, the surface of butterfly valve is provided with the head rod, one side fixedly connected with second gear of head rod, the tooth of second gear intermeshes with the tooth of first gear, one side fixedly connected with U-shaped pole of first gear, the surface rotation of U-shaped pole is connected with the rotary rod.
