Description

Novel butterfly valve handle

Technical Field

The utility model relates to a butterfly valve technical field specifically indicates a novel butterfly valve handle.

Background

A butterfly valve, also called a flap valve, is a regulating valve with simple structure, and can be used for the on-off control of low-pressure pipeline media, namely a valve which is opened and closed by rotating around a valve shaft, wherein a valve clack or a butterfly plate of a closing member is a disk. The valve can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like. The pipe mainly plays a role in cutting off and throttling. The butterfly valve opening and closing piece is a disc-shaped butterfly plate and rotates around the axis of the butterfly plate in the valve body, so that the opening and closing or adjusting purpose is achieved. The handle and the spindle head of the butterfly valve in the prior art are connected with two types, one type is that the spindle is moved flat through a bolt pressing shaft, when the valve is moved, the valve is likely to fall off due to the fact that the bolt is loosened, personnel injury is caused, the use safety is not high, the other type only penetrates through the handle and the spindle head through the elastic pin, the handle and the spindle head are not easy to detach and install again when faults occur, and the use effect is not good.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome above technical defect, provide a novel butterfly valve handle of security height, convenient to detach and installation.

In order to solve the technical problem, the utility model provides a technical scheme does: the utility model provides a novel butterfly valve handle, includes the valve body, vertical grafting has the valve rod in the valve body, fixed the cup jointing has the valve plate on the valve rod, the valve body upper end is equipped with the flange of its use of cooperation, be equipped with the valve handle of being connected with the valve rod in the middle of flange's the upper end, through hexagon socket head cap screw connection between valve rod and the valve handle.

Compared with the prior art, the utility model the advantage lie in: the novel butterfly valve handle of the utility model utilizes the inner hexagon screws to carry out partial connection on the sharp corner edge of the shaft side, thereby leading the valve handle and the valve rod to be tightly fixed together, having simple operation, time and labor saving and convenient disassembly and assembly; even if the inner hexagon screw is loosened, the shaft head notch can be clamped, danger cannot occur, and the use safety is improved.

As an improvement, the connecting flange is connected with the valve body through bolts, so that the valve body is convenient to disassemble and assemble.

As the improvement, be equipped with the axle sleeve that the cooperation valve rod used in the butterfly valve body, the valve rod is pegged graft in the axle sleeve, is convenient for rotate the valve rod like this.

Drawings

Fig. 1 is a schematic structural diagram of the novel butterfly valve handle of the present invention.

As shown in the figure: 1. the valve comprises a valve body, 2, a valve rod, 3, a valve plate, 4, a connecting flange, 5, a valve handle, 6, a socket head cap screw, 7 and a bolt.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The utility model provides a novel butterfly valve handle, includes valve body 1, vertical grafting has valve rod 2 in the valve body 1, valve plate 3 has been cup jointed to the fixed valve rod 3 that has cup jointed on the

valve rod

2, 1 upper end of valve body is equipped with flange 4 that cooperates its use, be equipped with the valve handle 5 of being connected with valve rod 2 in the middle of flange 4's the upper end, connect through hexagon socket head cap screw 6 between valve rod 2 and the valve handle 5.

The connecting flange 4 and the valve body 1 are connected through bolts 7.

The valve body 1 is internally provided with a shaft sleeve matched with the valve rod 2 for use, and the valve rod 2 is inserted in the shaft sleeve.

The utility model discloses when concrete implementation, combine the structure schematic diagram of a novel butterfly valve handle of figure 1 to know, the utility model discloses a novel butterfly valve handle is when using, on 1 original basis of valve body, utilizes hexagon socket head cap screw 6 to carry out the part on the sharp angle limit of 5 axle sides of valve handle and connects to make valve handle 5 and valve rod 2 tightly fixed together, not only easy operation, labour saving and time saving, convenient to detach and installation have improved stability moreover. After the use for a period of time, even the socket head cap screw 6 is not hard up, also can block the spindle nose breach, can not lead to the valve to drop, accidentally injures staff, can not take place danger, improved the safety in utilization. So said the utility model discloses a novel butterfly valve handle is not only the security high, convenient to detach and installation moreover.

The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
