Abstract

An integral slurry valve comprises a valve body, a valve rod and a shutter, wherein the inner wall of the valve body is embedded with a U-shaped elastic hollow seal bar, the edge of the shutter is contacted and fit with the seal bar in the sealing type, the valve body is integrally shaped, the chamber of the seal bar is provided with an internal elastic steel wire to form a support reinforce structure. The utility model adopts an integral valve body, with high strength and quick production and arranges an elastic steel wire in the chamber of the seal bar to improve flexibility, realize reliable support and be embedded into the inner wall of the valve body simply, to prevent the deformation and leakage of the seal bar and realize better seal performance, thereby confirming the zero leakage of the slurry valve and preventing flow resistance of bidirectional flowing medium.

Description

The integrated type Parallel Slide Valves

Technical field:

The utility model relates to a kind of gate valve, particularly Parallel Slide Valves.

Background technique:

General Parallel Slide Valves valve body all is a two-piece type, and two valve body clampings are tightly connected, and Zhuan Pei body strength is lower like this, and poor reliability is leaked easily.And general Parallel Slide Valves all is to utilize U type elastic hollow formula Stamping Steel Ribbon and the sealing of flashboard EDGE CONTACT that is inlaid in valve interior wall, but Stamping Steel Ribbon is damaged easily aging, and the rebound elasticity variation influences sealing reliability.When assembling or maintenance, Stamping Steel Ribbon does not support easy deformation, embeds valve interior wall and makes things convenient for inadequately.

Summary of the invention:

At the deficiencies in the prior art, the utility model provides a kind of body strength height, the integrated type Parallel Slide Valves of Stamping Steel Ribbon reliable performance.

The utility model comprises valve body, valve rod and flashboard, the inwall of valve body is embedded with the elastic hollow formula Stamping Steel Ribbon of U type, the edge of flashboard then cooperates with Stamping Steel Ribbon contact seal, and valve body is the global formation structure, and is built-in with elastic wire formation support reinforcing structure in the cavity of Stamping Steel Ribbon.

The utility model adopts the valve body of global formation, and the intensity height is not fragile, produces rapidly.At the mid-elastic wire that is placed with of the cavity of Stamping Steel Ribbon, add strong elasticity, to support reliably, assembling embeds in the valve interior wall very convenient, prevents Stamping Steel Ribbon distortion leakage, and sealability is better, has fully guaranteed the zero leakage of Parallel Slide Valves, and the medium two-way flow does not have flow resistance substantially.

Further specify the utility model below in conjunction with drawings and Examples.

Description of drawings:

Fig. 1 is embodiment's a main structure schematic representation;

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is the B portion enlarged view of Stamping Steel Ribbon among Fig. 1;

Fig. 4 is the C portion enlarged view of Stamping Steel Ribbon among Fig. 2.

Embodiment:

As shown in the figure, the inwall of valve body 1 is embedded with the elastic hollow formula Stamping Steel Ribbon 5 of U type, and the edge of flashboard 2 then cooperates with Stamping Steel Ribbon 5 contact seals, and valve body 1 is the global formation structure, and is built-in with elastic wire 6 formation support reinforcing structures in the cavity of Stamping Steel Ribbon 5.After valve body 1 was installed in the pipeline, when flashboard 2 was moved down by valve rod 3 drivings, the Stamping Steel Ribbon 5 of the edge of flashboard 2 and U type tightly touched sealing, throttle down.When moving on the flashboard 2, its lower limb and Stamping Steel Ribbon 5 disengage, the valve latus rectum is opened, can realize the two-way flow of medium, and the hollow elasticity structure of Stamping Steel Ribbon 5 can resilience, make the inwall of valve body 1 not have significant depressions, can prevent the deposition of fiber, particle etc. in the slurry medium, reduce flow resistance.

In fact, the cross section of the Stamping Steel Ribbon 5 of present embodiment is a matrix, and the contact matching face of itself and flashboard 2 is provided with groove 7 and constitutes the sealing reinforced structures.Wrapped by groove 7 when the edge of flashboard 2 and Stamping Steel Ribbon 5 tightly touch like this, contact more fully, seal also more reliable.The driving structure of Parallel Slide Valves generally can adopt blind rod type, and promptly the support 4 that is positioned on the valve body 1 of valve rod 3 is rotationally connected, and 9 on moving nut that flashboard 2 tops connect and valve rod 3 are threaded to move and cooperate.Present embodiment then is provided with long groove 8 and scale on the surface of support 4, form the flashboard position and observe indicating device, generally can also be on moving nut 9 concatenation pointer, can observe out the upward stroke of flashboard 2 so very easily, be the big or small degree of valve opening, easier adjusting flow.
