The utility model has the advantages of: valve striking hand wheel adds the striking piece outside valve -stem nut, realize opening and close of valve through the inertia behind hand wheel self striking during rotation, labour saving and time saving, and the operation is very convenient.

Description

A kind of valve Impact handwheel

Technical field

The utility model relates to a kind of valve handle, particularly a kind of valve Impact handwheel.

Background technique

Valve handle is a kind of parts opened and closed for control valve, traditional handwheel directly coordinates with Stem Mut, need during use that operational torque is enough large just can make it rotate, very labor intensive, and use inconvenient, therefore be badly in need of the valve Impact handwheel that a kind of operational torque of development is little, easy to use, through retrieval, do not find the same or analogous technological scheme with the utility model.

Model utility content

The technical problems to be solved in the utility model is to provide a kind of operational torque valve Impact handwheel little, easy to use.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of valve Impact handwheel, and its innovative point is: comprise handwheel body and the Stem Mut with this mates of handwheel; Described Stem Mut is column, outer end nested arrangements one impact block, described impact block is made up of in integrative-structure the fan-shaped of four relative symmetry, comprises the sector unit A of a pair short radius and the sector unit B of a pair semi major axis, has a Hexagon through hole inserted for Stem Mut in the middle part of this impact block; Have a cavity placed for impact block in the middle part of described handwheel body, described cavity is made up of the sector structure of four relative symmetry, comprises a pair fan-shaped chamber A identical with sector unit A radius and a pair fan-shaped chamber B identical with sector unit B radius.

Further, the central angle summation of described a pair sector unit A and a pair sector unit B is 360o, and the round angle summation of a pair fan-shaped chamber A and a pair fan-shaped chamber B is also 360o.

Further, the central angle of described sector unit B is 45o.

Further, the round angle of described fan-shaped chamber A is 40o.

The utility model has the advantage of:

1) valve Impact handwheel sets up impact block outside Stem Mut, is realized the keying of valve during rotation by the inertia after handwheel self shock, time saving and energy saving, easy to operate;

2) in impact block, the central angle of the sector unit B of large radius is less than the central angle of the fan-shaped chamber B of large radius in cavity, facilitates handwheel to have the space of enough own rotation, reasonable in design.

Embodiment

As shown in Figure 1, the utility model discloses a kind of valve Impact handwheel, the Stem Mut 2 comprising handwheel body 1 and match with handwheel body 1.

As shown in Figure 2, Stem Mut 2 is in column structure, outer end nested arrangements one impact block, this impact block is made up of in integrative-structure the fan-shaped of four relative symmetry, comprise the sector unit A6 of a pair short radius and the sector unit B8 of a pair semi major axis, wherein the central angle summation of a pair sector unit A6 and a pair sector unit B8 is 360o, and the central angle of sector unit B8 is 45o, has a Hexagon through hole 7 inserted for Stem Mut 2 in the middle part of this impact block.

As shown in Figure 3 and Figure 4, there is in the middle part of handwheel body 1 cavity 3 placed for impact block, cavity 3 is made up of the sector structure of four relative symmetry, comprise a pair fan-shaped chamber A4 identical with sector unit A6 radius and a pair fan-shaped chamber B5 identical with sector unit B8 radius, the round angle summation of a pair fan-shaped chamber A4 and a pair fan-shaped chamber B5 is also 360o, and the round angle of this fan-shaped chamber A4 is 40o simultaneously.

When valve Impact handwheel rotates, central angle due to the sector unit B8 of radius large in impact block is less than the central angle of the fan-shaped chamber B5 of large radius in cavity 3, handwheel body 1 is made to have the space of certain own rotation, when handwheel body 1 own rotation, with the inertia that handwheel body 1 rotates, impact block is impacted, and then utilize impact force to reach object to valve opening or closedown.

More than show and describe basic principle of the present utility model and major character.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
