Embodiment Construction

[0016] An impact handwheel suitable for a globe valve comprises an impact handwheel 1 and an impact sleeve 2, wherein the impact sleeve 2 is sleeved outside the impact handwheel 1.

[0017] The impact handwheel 1 and the impact sleeve 2 are all made of precision castings, only the plane is turned, and the complex plane is not processed, and the processing cost is low.

[0018] The torque of the impact handwheel satisfies the following formula:

[0019] T=Ja=mi 2 a

[0020] In the formula: a acceleration

[0021] J moment of inertia J=mi 2

[0022] m mass

[0023] i Inertia radius = impact sleeve radius.

Abstract

The invention belongs to an impact hand wheel and particularly relates to an impact hand wheel applicable to a stop valve. The impact hand wheel applicable to the stop valve comprises an impact hand wheel body and an impact sleeve, wherein the impact sleeve is connected out of the impact hand wheel body in a sleeving manner. The impact hand wheel applicable to the stop valve has the following advantages: 1, only two parts namely the impact hand wheel body and the impact sleeve are included, so that the structure is simple and the assembling is convenient; and 2, as the large-diameter impact sleeve is adopted, the impact force is large, and the impact sleeve can replace a hand gear, so that the product cost is reduced. The torque provided by the impact hand wheel is in direct proportion to the accelerated velocity and mass of the impact hand wheel and the radial square of the impact sleeve, so that when the difference of the accelerated velocity and mass is slight, the torque of the impact hand wheel is mainly determined by the diameter of the impact sleeve. According to the invention, the large-diameter impact sleeve is adopted to provide large torque and large impact force.

Description

technical field [0001] The invention belongs to an impact handwheel, in particular to an impact handwheel suitable for a stop valve. Background technique [0002] The impact handwheel generally consists of an impact handwheel, an impact sleeve, a handwheel cover and a set of screws. There are two major disadvantages in this impact handwheel. First, the number of parts is large, the amount of processing is large, the assembly is time-consuming, and it is easy to break down; second, the diameter of the impact sleeve is small, so the impact force produced is not large. Contents of the invention [0003] The object of the present invention is to provide an impact handwheel suitable for a shut-off valve in view of the defects in the prior art. [0004] Realize the structural technology of the object of the present invention: [0005] An impact handwheel suitable for a stop valve comprises an impact handwheel and an impact sleeve, wherein the impact sleeve is sleeved outside t...
