Abstract
The utility model discloses an anti-coking gate valve which comprises a valve body, a valve rod, a valve cover, a gate plate and a hand wheel, wherein the valve rod and the gate plate are movably connected through a connection sleeve in a clamped mode. The anti-coking gate valve further comprises an air inflation cavity, the upper end of the air inflation cavity is fixedly connected with the valve cover in a sealed mode, the lower end of the air inflation cavity is fixedly connected with the valve body in a sealed mode, an air inflation nozzle is arranged in the air inflation cavity and connected with an external air inflator, an anti-slide concave is formed in the hand wheel, the air inflation cavity and the valve body are of an integrated structure, and the air inflation nozzle is in sealed connection with the air inflation cavity. The anti-coking gate valve has the advantages of being simple in structure, coking resistant, low in manufacturing cost, high in flow and the like.
Description
Technical field:
The utility model belongs to valve field, particularly a kind of anti-coking gate valve.
Background technique:
The valve of traditional anti-coking only has ball valve, and the ball valve machining accuracy is high, involves great expense, and should not use in high temperature.
The model utility content:
For the deficiencies in the prior art, the utility model provides a kind of anti-coking gate valve.
To achieve these goals, the utility model is that the technological scheme that its technical problem of solution is taked is:
A kind of anti-coking gate valve, comprise valve body, valve rod, valve gap, flashboard and handwheel, valve rod and flashboard are by connecting sleeve activity clamping, also comprise inflatable chamber, the affixed valve gap of inflatable chamber upper end sealing, the affixed valve body of lower end sealing, be provided with charging air inlet in inflatable chamber, charging air inlet is connected with extraneous inflator, and handwheel is provided with anti-slip recess.
Described inflatable chamber and valve body are the integral type structure.
Described charging air inlet and inflatable chamber are tightly connected.
The beneficial effects of the utility model: the utility model is simple in structure, but anti-coking, the advantage such as cost is low, and flow is large.
The accompanying drawing explanation:
Fig. 1 is the utility model structural representation.
Embodiment:
A kind of anti-coking gate valve as shown in Figure 1, comprise valve body 1, valve rod 2, valve gap 3, flashboard 4 and handwheel 5, valve rod 2 passes through connecting sleeve 6 activity clampings with flashboard 4, also comprise inflatable chamber 7, the affixed valve gap 3 of inflatable chamber 7 upper end sealing, the affixed valve body 1 of lower end sealing, be provided with charging air inlet 8 in inflatable chamber 7, charging air inlet 8 is connected with extraneous inflator.Described inflatable chamber 7 is the integral type structure with valve body 1.Described charging air inlet 8 is tightly connected with inflatable chamber 7.Handwheel is provided with anti-slip recess.
When flashboard 4 was opened fully, the gas in inflatable chamber 7 entered valve body 1 by inflatable chamber 7 and valve body 1 connectivity part, caused the medium in valve body 1 can be in inflatable chamber 7 and valve body 1 connectivity part coking.The utility model is simple in structure, but anti-coking, the advantage such as cost is low, and flow is large.
Those ordinary skill in the art's simple change and replacement are all within protection domain of the present utility model.
