Abstract

The invention discloses an auxiliary switch device for a stop valve, and belongs to the technical field of valve structures. The auxiliary switch device comprises a fixed disc, a movable disc, a torsion part and a clamping handle, wherein the fixed disc is used for being fixed to a valve body of the stop valve in a sleeving mode, the movable disc is arranged on the periphery of the fixed disc in asleeving manner and can rotate relative to the axial direction of the fixed disc, a plurality of clamping units are sequentially arranged on the periphery of the movable disc, one end of the torsionpart is used for being fixed to a rotary core of the stop valve, the other end of the torsion part is fixed to the movable disc, the clamping handle comprises a first clamping rod and a second clamping rod which form clamp-shaped pivot joint fit, the first end of the first clamping rod is connected to the fixed disc, the second end of the first clamping rod is a first handle end, the first end ofthe second clamping rod is provided with a clamping hook capable of being connected to any clamping unit in a hooked mode, and the second end of the second clamping rod is a second handle end. According to the auxiliary switch device for the stop valve, the torsion acting force of the valve body and the internal rotary core of the stop valve is converted into the acting force between the two clamping rods of the clamping handle, and the switch torsion operation of the stop valve can be more stable through the auxiliary switch device.

Description

technical field [0001] The invention relates to the technical field of valve structures, in particular to an auxiliary switch device for a shut-off valve and a shut-off valve. Background technique [0002] At present, globe valves are often used to control the on-off of refrigerant pipelines in air conditioners. Among them, right-angle valves are the most commonly used. The front and rear pipelines of right-angle valves are 90 degrees. Due to the small size of the valve body, the general length is about 5cm. , with a height of about 4cm, the connected front and rear pipelines will be subjected to shear force when the rotor is twisted to control the switch, especially in the initial stage of opening. [0003] Generally, the operation of the twist stop valve is to fix the valve body with a wrench, and then use the inner hexagon to turn the core of the stop valve. This mode of operation sometimes has the problem that it is difficult to twist, and the initial twisting requires ...
