Abstract

The utility model discloses a pneumatic gate valve which comprises a valve body, wherein a valve rod is installed on the valve body, a clamping groove is formed in the valve rod, a rotating handle is arranged on the valve body, a clamping rod is arranged on the rotating handle and is rotationally connected with a connecting rod through a bearing, a plurality of bent rods are distributed on the side wall of the valve body, grooves are formed in the bent rods, and positioning pieces for limiting the connecting rod are arranged in the grooves. According to the utility model, the connecting rod moves upwards in the vertical direction under the action of the elastic force of the spring, so that the clamping rod is far away from the clamping groove on the valve rod, the valve rod cannot rotate together when the rotating hand is rotated, the gate valve cannot be influenced even if the rotating hand is rotated by external force, and the valve rod cannot rotate, so that the gate valve is more convenient to use, and the situation of mistaken touch is avoided.

Description

Pneumatic gate valve

Technical Field

The utility model relates to the technical field of gate valves, in particular to a pneumatic gate valve.

Background

The gate valve is a shutter plate, the movement direction of the shutter plate is perpendicular to the fluid direction, and the gate valve can only be fully opened and fully closed and cannot be adjusted and throttled. The gate valve seals through disk seat and flashboard contact, and the sealed face can build up welding metal material in order to increase the wearability usually, like the build up welding, stainless steel etc. and the flashboard has rigidity flashboard and elasticity flashboard, and according to the difference of flashboard, the gate valve divide into rigidity gate valve and elasticity gate valve.

Because the gate valve need not to rotate the runner of gate valve once more after opening, consequently the gate valve can appear pivoted phenomenon when receiving external force, can influence the effect of gate valve, consequently need to improve it for the gate valve can not touched by the mistake.

SUMMERY OF THE UTILITY MODEL

The utility model aims to: in order to solve the problems, a pneumatic gate valve is provided.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a pneumatic gate valve, includes the valve body, install the valve rod on the valve body, the draw-in groove has been seted up on the valve rod, be equipped with the commentaries on classics hand on the valve body, be equipped with the kelly on the commentaries on classics hand, the kelly passes through the bearing and is connected with the connecting rod rotation, the lateral wall distribution of valve body has a plurality of knee rods, set up flutedly on the knee rod, be equipped with the setting element spacing to the connecting rod in the recess.

Preferably, the setting element includes the montant, the montant runs through the round hole of seting up on the connecting rod, the bottom welding of connecting rod has the spring, the spring housing is established on the montant.

Preferably, the clamping groove and the clamping rod are rectangular, and the inner wall of the clamping groove is provided with an elastic rubber block.

Preferably, the inner wall of the round hole is smooth and provided with a wear-resistant layer.

Preferably, the surface of the rotating hand is provided with anti-skid lines.

In summary, due to the adoption of the technical scheme, the utility model has the beneficial effects that:

1. this application is through making the connecting rod rebound in vertical direction under the spring action, consequently leads to the kelly to keep away from the draw-in groove on the valve rod, can't make the valve rod together rotate when rotating the hand, also can not lead to the fact the influence to the gate valve when receiving external force hand rotation, and the valve rod can not rotate, therefore the use of gate valve more saves worry, need not the condition that worry mistake touched.

2. This application is through pressing the commentaries on classics hand, when the kelly of commentaries on classics hand stretched into the draw-in groove of valve rod, it can drive the valve rod rotation to rotate the commentaries on classics hand, therefore the operation is comparatively convenient, need not loaded down with trivial details step, the last hand that the staff can be quick.

illustration of the drawings:

1. a valve body; 2. a valve stem; 3. a card slot; 4. turning the hand; 5. a clamping rod; 6. a connecting rod; 7. bending a rod; 8. a groove; 9. a vertical rod; 10. a circular hole; 11. a spring.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution:

the utility model provides a pneumatic gate valve, including valve body 1, install valve rod 2 on the valve body 1, draw-in groove 3 has been seted up on the valve rod 2, be equipped with on the valve body 1 and change hand 4, the surface of changing hand 4 is equipped with anti-skidding line, be equipped with kelly 5 on changing hand 4, draw-in groove 3 is the rectangle with kelly 5, and the inner wall of draw-in groove 3 is equipped with elastic rubber block, kelly 5 rotates through bearing and connecting rod 6 to be connected, the lateral wall distribution of valve body 1 has a plurality of knee 7, set up recess 8 on the knee 7, be equipped with in the recess 8 to the 6 spacing setting elements of connecting rod.

Specifically, as shown in fig. 1 and 2, the positioning member includes a vertical rod 9, the vertical rod 9 penetrates through a round hole 10 formed in the connecting rod 6, the inner wall of the round hole 10 is smooth and provided with a wear-resistant layer, a spring 11 is welded at the bottom of the connecting rod 6, the spring 11 is sleeved on the vertical rod 9, and the spring 11 gives the force to the connecting rod 6 to enable the connecting rod 6 to vertically move upwards, so that the clamping groove 3 is far away from the clamping rod 5.

In conclusion, during the start-up gate valve that this embodiment provided, press runner 4 for kelly 5 drives connecting rod 6 and together moves down in the vertical direction, until the tip and the draw-in groove 3 block of kelly 5, because kelly 5 is the rectangle with draw-in groove 3, consequently rotate runner 4, valve rod 2 can be together rotatory thereupon, connecting rod 6 compression spring 11, loosen the power to runner 4 after the operation is accomplished, connecting rod 6 and runner 4 can together the rebound under spring 11's elasticity, until kelly 5 breaks away from with draw-in groove 3, it can not drive valve rod 2 rotatory to rotate runner 4 this moment.

The previous description of the embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model.
