Abstract
The utility model relates to a pneumatic air valve with a visible working state, and belongs to the technical field of coal dressing and jigging equipment. The pneumatic air valve with the visible working state comprises a valve body (5) and an air cylinder (3); one end of the air cylinder is connected with the valve body through an air cylinder connection rod (4); an air cylinder shaft (2) is stretched out from the other end of the air cylinder; and a protective cover (1) is arranged outside the stretching end of the air cylinder shaft. The pneumatic air valve has the advantages that: as the air cylinder shaft is stretched out from the other end of the air cylinder, the air cylinder and the valve body of the pneumatic air valve are combined ingeniously, and the working state of a driving air cylinder can be observed directly by observing the stretching state of the air cylinder shaft and is free from influence of factors such as environment and the like; and the protective cover can protect the stretched air cylinder shaft and the air cylinder.
Description
Affiliated technical field:
The utility model relates to the visual pneumatic air-valve of a kind of working state, belongs to coal separation jigging equipment technical field.
Background technique:
At present, coal separation with jigger on, pneumatic air-valve is by valve body and drive cylinder and form, valve body and air cylinder connecting rod link together.The problem that background technique exists is: the driving cylinder of pneumatic air-valve needs frequent movement, the field personnel can not observe the working state that drives cylinder intuitively, can only rely on sound to judge, be unfavorable for accurately control and plant maintenance, when particularly the running environment noise is bigger, can accurately not judge the runnability of cylinder.
The model utility content:
The utility model purpose provides the visual pneumatic air-valve of a kind of working state, can see the working state that drives cylinder intuitively, solves the problems referred to above that exist in the background technique.
The technical solution of the utility model is: the pneumatic air-valve that working state is visual, comprise valve body, cylinder, and an end of cylinder links together by air cylinder connecting rod and valve body, and cylinder axis stretches out from the other end of cylinder.
Outside at the cylinder axis external part is provided with protective housing; Said protective housing can be the protective housing that transparent material is made, and also can be provided with viewing window on protective housing, is convenient to observe intuitively the working state that drives cylinder.
Also be provided with cylinder axis extrusion measuring mechanism at the cylinder axis external part, accurate MEASUREMENT OF STEAM cylinder working state, and be provided with the control mechanism of coupling, measurement signal is controlled.
The beneficial effects of the utility model: owing to the other end of cylinder axis from cylinder stretches out, cylinder combines with the valve body of pneumatic air-valve is ingenious, can be by observing the state that cylinder axis stretches out, observe directly the working state that drives cylinder, be not subjected to factor affecting such as environment, protective housing can protect cylinder axis and the cylinder itself that stretches out.
Fig. 1 is the utility model example structure schematic representation;
Among the figure: protective housing 1, cylinder axis 2, cylinder 3, air cylinder connecting rod 4, valve body 5.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
The pneumatic air-valve that working state is visual comprises valve body 5, cylinder 3, and an end of cylinder links together by air cylinder connecting rod 4 and valve body, and cylinder axis 2 stretches out from the other end of cylinder.Be provided with protective housing 1 in the outside of cylinder axis external part, said protective housing is the protective housing that transparent material is made, and is convenient to observe intuitively the working state that drives cylinder.
Claims (5)
