Description

Butterfly type locking valve

Technical Field

The utility model relates to the technical field of locking valves, in particular to a butterfly type locking valve.

Background

The locking valve is a valve device composed of a valve body, a valve core, a valve rod and a locking mechanism.

At present, in the use process of the existing butterfly-type locking valve, the opening condition of the locking valve is not easy to observe, and the valve plate is inconvenient to fix, so that the use of the butterfly-type locking valve is not facilitated, and therefore, the butterfly-type locking valve is provided.

Disclosure of Invention

The utility model aims to provide a butterfly type locking valve, which solves the problems that a valve plate is inconvenient to fix and the opening condition of the locking valve is inconvenient to observe in the existing butterfly type locking valve.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the butterfly type locking valve comprises a valve body, wherein a shaft rod is rotatably connected to the valve body, the bottom end of the shaft rod penetrates through the valve body and is provided with a valve plate, the top end of the shaft rod is provided with a gear, scales are arranged on the gear, and a fixing mechanism is arranged on the valve body.

Preferably, the fixing mechanism comprises a mounting plate, and the mounting plate is fixedly mounted on the valve body.

Preferably, a spring is arranged on the mounting plate.

Preferably, one end of the spring is provided with a bolt, and one end of the bolt penetrates through the mounting plate.

Compared with the prior art, the utility model has the beneficial effects that:

1. the utility model is convenient for observing the opening condition of the locking valve by arranging the gear with scales.

2. The utility model has the advantage that the fixing mechanism is arranged, so that the purpose of conveniently fixing the valve plate is achieved.

Drawings

FIG. 1 is a schematic diagram of the overall structure of the present utility model;

fig. 2 is a schematic view of a gear according to the present utility model.

In the figure: 1. a valve body; 2. a gear; 3. a shaft lever; 4. a valve plate; 51. a spring; 52. a plug pin; 53. and (3) mounting a plate.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

Please refer to fig. 1 and 2, a butterfly-type locking valve in the illustration, including valve body 1, the last rotation of valve body 1 is connected with axostylus axostyle 3, and axostylus axostyle 3's shape is cylindrical pole, and valve plate 4 is equipped with to the bottom of axostylus axostyle 3, and the shape of valve plate 4 is the disc shaped plate, and the top of axostylus axostyle 3 is equipped with gear 2, through being provided with gear 2, is convenient for accept the grafting of bolt 52, is provided with the scale through its surface simultaneously, is convenient for observe the condition of opening of locking valve, is equipped with the scale on the gear 2, is equipped with fixed establishment on the valve body 1, through being provided with fixed establishment, plays the purpose of conveniently fixing valve plate 4.

Meanwhile, the fixing mechanism comprises a mounting plate 53, the shape of the mounting plate 53 is square, the mounting plate 53 is provided with the square plate 53, the mounting of the spring 51 is convenient to carry, the mounting plate 53 is fixedly mounted on the valve body 1, the spring 51 is arranged on the mounting plate 53, one end of the spring 51 is provided with a bolt 52, the bolt 52 is arranged, the mounting plate is convenient to carry between teeth on the gear 2, the purpose of fixing the gear 2 is achieved, and one end of the bolt 52 penetrates through the mounting plate 53.

When the butterfly type locking valve is used: when the locking valve needs to be opened, the bolt 52 is pulled firstly, one end of the bolt 52 is pulled away from the gear 2, then the gear 2 can be rotated, the gear 2 drives the shaft lever 3 to rotate, the shaft lever 3 drives the valve plate 4 to rotate, thereby the purpose of opening the locking valve is achieved, scales are arranged on the gear 2, the indication of the bolt 52 is matched, the opening condition of the locking valve is convenient to know, the use of the locking valve is facilitated, after the valve plate 4 rotates to a proper position, the bolt 52 is loosened, and the bolt 52 is inserted between teeth of the gear 2 under the action of the spring 51, thereby the purpose of fixing the gear 2 and the valve plate 4 is achieved.

It is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
