Abstract

The utility model relates to a multifunctional built-in-bar sluice valve which relates to the improvement of the structure of the built-in-bar sluice valve. The utility model solves the problem of the slow opening and closing of the built-in-bar sluice valve at present, and provides the multifunctional built-in-bar sluice valve with rapid opening and closing. The utility model comprises a valve body (1). A valve rod (6) which is provided with a hand wheel (7) is fixed on the valve body (1). The structural main points are that: the bidirectional screw thread is arranged on the valve rod (6); a nut (5) and a nut (2) which are corresponded with the bidirectional screw thread are respectively arranged in an upper flashboard (4) and a lower flashboard (3) which have the relative movement with the valve body (1).

Description

Multi-functional inside screw non-rising stem type gate valve

Technical field:

The utility model relates to the improvement of inside screw non-rising stem type gate valve structure.

Background technique:

The closing structure of present widely used blind rod type gate valve mainly is whole board-like, and it has the characteristics such as simple of making; Its shortcoming is that switch is slow, can not use as the regulating valve of regulating flow, pressure on engineering, can only do pass, closed form valve.

The model utility content:

The utility model is exactly to solve the slow problem of present inside screw non-rising stem type gate valve open and close, provides a kind of open and close multi-functional efficiently inside screw non-rising stem type gate valve.

The purpose of this utility model is achieved in that the utility model comprises valve body, valve rod with handwheel is fixed on the valve body, its structure outline is to have bidirectional helical on the valve rod, and being separately positioned on valve body with the corresponding nut of bidirectional helical has in the upper flashboard, lower flashboard of relative movement.

The beneficial effects of the utility model:

Valve rod of the present utility model has bidirectional helical, being separately positioned on valve body with the corresponding nut of bidirectional helical has in the upper flashboard, lower flashboard of relative movement, just the speed of inside screw non-rising stem type gate valve twice is closed or Open valve usually, and therefore, the open and close valve event is quick; The utility model can be widely used in flow, the pressure of regulating the pipeline inner fluid.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the A of Fig. 1 is to view.

Embodiment:

The utility model comprises valve body 1, has on valve rod 6 fixed valve bodies 1 of handwheel 7, has bidirectional helical on the valve rod 6, with the corresponding nut 5 of bidirectional helical, nut 2 is separately positioned on and valve body 1 has in the upper flashboard 4, lower flashboard 3 of relative movement.

Below in conjunction with a description of drawings course of action of the present utility model:

Drive valve: handwheel 7 rotates counterclockwise, and nut 5, nut 2 drive upper flashboard 4 simultaneously respectively, lower flashboard 3 makes progress, moves down, till the flow of satisfying the demand;

Close valve: handwheel 7 clockwise rotates, nut 5, nut 2 drive simultaneously respectively upper flashboard 4 to move down, lower flashboard 3 upwards moves, till the surface of contact close proximity of upper flashboard 4, lower flashboard 3 touches, stops fluid to pass through this valve.

Claims

1. multi-functional inside screw non-rising stem type gate valve, comprise valve body (1), have on valve rod (6) fixed valve body (1) of handwheel (7), it is characterized in that having bidirectional helical on the valve rod (6), being separately positioned on valve body (1) with the corresponding nut of bidirectional helical (5), nut (2) has in the upper flashboard (4), lower flashboard (3) of relative movement.
