Description

Novel butterfly valve locking device

Technical Field

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

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 butterfly valve in the prior art generally locks the position of the valve by means of driving, and the butterfly valve cannot be locked when the driving is removed, so that the butterfly valve is low in flexibility, complex in structure and inconvenient to use.

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 locking device that the flexibility is high, simple structure.

In order to solve the technical problem, the utility model provides a technical scheme does: the utility model provides a novel butterfly valve locking device, includes the valve body, the vertical grafting of the upper end of valve body has last valve rod, the vertical grafting in bottom of valve body has lower valve rod, go up and connect through the valve plate between the adjacent both ends of valve rod and lower valve rod, be equipped with the disk seat in the valve body, it has long axle sleeve to cup jointed on the upper end that is located the disk seat on the valve rod, go up the position that is close to the inside upper end of valve body on the valve rod from last to having cup jointed retaining ring, packing ring, axle retaining ring and stub axle sleeve down in proper order, it is equipped with the draw-in groove to be equipped with in the below that is located the stub axle sleeve on the valve rod, the outside threaded connection of valve body has spacing bolt, spacing bolt.

Compared with the prior art, the utility model the advantage lie in: the novel butterfly valve locking device of the utility model can realize the opening and closing of a plurality of valves by one driving device by utilizing the matching of the limiting bolt and the clamping groove on the upper valve rod, thereby improving the use flexibility; the limiting processing can be realized by utilizing the limiting bolt and the clamping groove, the structure is simple, the operation is convenient, and the using effect is improved.

As an improvement, an O ring sleeved on the upper valve rod is arranged in the short shaft sleeve, so that the sealing performance of the valve body is improved.

Drawings

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

Fig. 2 is a side view of the novel butterfly valve locking device of the present invention.

As shown in the figure: 1. the valve comprises a valve body, 2, an upper valve rod, 3, a lower valve rod, 4, a valve plate, 5, a valve seat, 6, a long shaft sleeve, 7, a hole retainer ring, 8, a gasket, 9, a shaft retainer ring, 10, a short shaft sleeve, 11, a clamping groove, 12, a limiting screw, 13 and an O ring.

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 locking device, includes valve body 1, the vertical grafting of upper end of valve body 1 has last valve rod 2, the vertical grafting in bottom of valve body 1 has lower valve rod 3, it connects through valve plate 4 between the both ends that go up valve rod 2 and lower valve rod 3 are adjacent, be equipped with disk seat 5 in the valve body 1, it has cup jointed long axle sleeve 6 to go up the upper end that lies in disk seat 5 on the valve rod 2, go up the position that is close to 1 inside upper end of valve body on the valve rod 2 and from last to having cup jointed retaining ring 7, packing ring 8, axle retaining ring 9 and stub axle sleeve 10 down in proper order, it is equipped with draw-in groove 11 to go up the below that lies in stub axle sleeve 10 on the

valve rod

2, 1 outside threaded connection of valve body has stop bolt 12, stop bolt 12 is gone up and is extended to draw-.

An O-ring 13 sleeved on the upper valve rod 2 is arranged in the short shaft sleeve 10.

The utility model discloses when concrete implementation, combine the structural schematic diagram of a novel butterfly valve locking device of figure 1 and the side view of a novel butterfly valve locking device of figure 2 to know, the utility model discloses a novel butterfly valve locking device when using, at first mill out a draw-in groove 11 at the intermediate position of last valve rod 2 to the position relative with draw-in groove 11 on the 1 side of valve body is beaten the screw hole, when the valve moves to open position or off-position, locks with spacing bolt 12, can dismantle the switch that drive arrangement was used for next valve like this, thereby realizes a plurality of valves of drive arrangement switch, has improved and has used the flexibility. Utilize a spacing bolt 12, a draw-in groove 11 and a screw hole, can realize spacing processing, simple structure, the operation of being convenient for has improved the result of use.
