Abstract
The utility model discloses an anti-scale wear-resistance sluice valve which is provided with a valve body (1). A flow passage (2) is arranged on the valve body (1), and a valve plate (3) is arranged in the valve body (1). The valve plate (3) is connected with the lifting starting and stopping mechanism of the valve plate. The utility model is characterized in that: the external surface of the valve plate (3) is tightly contacted with the inner wall (9) of the valve plate cavity in the valve body (1); the valve plate (3) is composed of two valve plates. The valve plate (3) is connected with the lifting starting and stopping mechanism of the valve plate through a valve plate connecting plate (4) and a valve plate connecting pin (5). A butterfly spring is provided between the two valve plates. Because the inner wall of the valve plate cavity is tightly contacted with the external surface of the valve plate, the inner wall of the valve plate cavity and the external surface of the valve plate are difficult to scale the formation. The utility model has the advantage of easy starting and stopping.
Description
One, technical field:
The utility model relates to a kind of antiscale wear-resistant sluice valve that is used to carry liquid or slurry.
Two, background technique:
At present, known gate valve has valve body, has runner on the valve body, has valve plate in the valve body, and valve plate is connected with valve plate lifting opening/closing mechanism, and tool valve plate chamber in the valve body when valve is in opening state, has the gap between the inwall in valve plate chamber and the valve plate.Its deficiency is the plate face of valve plate and the easy fouling of inwall in valve plate chamber, causes the valve opening and closing difficulty.
Three, summary of the invention:
The purpose of this utility model is to provide a kind of antiscale wear-resistant sluice valve, to overcome the deficiency of known technology.
The utility model is achieved in that a kind of antiscale wear-resistant sluice valve, it has valve body (1), has runner (2) on the valve body (1), has valve plate (3) in the valve body (1), valve plate (3) is connected with valve plate lifting opening/closing mechanism, the inwall (9) in the valve plate chamber in the outer surface that its special way is valve plate (3) and the valve body (1) closely contacts, valve plate (3) is made up of two valve plates, valve plate (3) is connected with valve plate lifting opening/closing mechanism with valve plate coupling bar (5) by valve plate connecting plate (4), and butterfly spring (6) is set between two valve plates.
Antiscale wear-resistant sluice valve of the present utility model can be that scale removal chamber (7) is set in the bottom of runner.
Antiscale wear-resistant sluice valve of the present utility model can be that the inwall at runner (2) is lined with wearing layer (8).
Antiscale wear-resistant sluice valve of the present utility model can be that the wearing layer (8) on the inwall of runner (2) is the cast stone wearing layer.
The wear-resisting gate valve of the antiscale that the utility model provides, because the inwall in valve plate chamber contacts with the intimate of valve plate, the inwall in valve plate chamber and the outer surface of valve plate are less scaling, have to open and close to be easy to advantage.
Four, description of drawings:
Fig. 1: a kind of structural representation of the utility model.
Five, embodiment:
The utility model is described in further detail in conjunction with embodiment with reference to accompanying drawing.
Embodiment 1, accompanying drawing has provided a kind of concrete structure of the utility model, consult Fig. 1, a kind of antiscale wear-resistant sluice valve, it has valve body (1), has runner (2) on the valve body (1), has valve plate (3) in the valve body (1), valve plate (3) is connected with valve plate lifting opening/closing mechanism, the inwall (9) in the valve plate chamber in the outer surface of valve plate (3) and the valve body (1) closely contacts, valve plate (3) is made up of two valve plates, and valve plate (3) is connected with valve plate lifting opening/closing mechanism with valve plate coupling bar (5) by valve plate connecting plate (4), and butterfly spring (6) is set between two valve plates.Scale removal chamber (7) is set in the bottom of runner.Inwall at runner (2) is lined with wearing layer (8).Wearing layer (8) is the cast stone wearing layer.
Claims (4)
1, a kind of antiscale wear-resistant sluice valve, it has valve body (1), has runner (2) on the valve body (1), has valve plate (3) in the valve body (1), valve plate (3) is connected with valve plate lifting opening/closing mechanism, and the inwall (9) in the valve plate chamber in the outer surface that it is characterized in that valve plate (3) and the valve body (1) closely contacts, and valve plate (3) is made up of two valve plates, valve plate (3) is connected with valve plate lifting opening/closing mechanism with valve plate coupling bar (5) by valve plate connecting plate (4), and butterfly spring (6) is set between two valve plates.
