Abstract
The utility model provides a pressure difference-adjustable anti-explosion valve, relates to an anti-explosion valve, and particularly relates to a pressure difference adjustable pipeline anti-explosion valve. The pressure difference-adjustable anti-explosion valve comprises a cam shaft (1), a valve rod (2), a spring (3), a valve body (4), an adjusting hand wheel (5) and end covers (6), wherein the spring (3) is mounted inside the valve body (4) through the valve rod (2); the cam shaft (1) is fixedly arranged on the valve body (4) through the two end covers (6); a middle cam of the cam shaft (1) is arranged on the upper end face of the valve rod (2); and the adjusting hand wheel (5) is arranged at one end of the cam shaft (1). According to the pressure difference-adjustable anti-explosion valve, the disadvantages that the opening size of the traditional anti-explosion valve cannot be adjusted and the pressure value for closing cannot be adjusted are solved; and meanwhile, the problem of the poor sealing performance of plane sealing adopted by the traditional anti-explosion valve also can be solved, downstream liquid is prevented from continuously flowing out from a cracked part to be wasted, and the safety is further ensured.
Description
Technical field:
The utility model relates to a kind of explosion-proof valve, the adjustable pipeline explosion-proof valve of especially a kind of pressure reduction.
Background technique:
Pressure fluid pipeline (such as tap water pipe line, pipeline road and hydraulic system) a large amount of fluids can occur and leak and waste when pipeline burst or artificial destruction occurring, even serious accident can occur, tradition explosion-proof valve employing plane sealing and valve openings of sizes are unadjustable, can avoid above situation to occur by explosion-proof valve of the present invention is installed at pipeline.
The model utility content:
The purpose of this utility model provides the adjustable explosion-proof valve of a kind of pressure reduction, and it is unadjustable and close the nonadjustable drawback of required force value that it can solve traditional explosion-proof valve openings of sizes, can solve again traditional explosion-proof valve simultaneously and adopt the poor problem of plane sealing sealing.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions:
It comprises camshaft 1, valve rod 2, spring 3, valve body 4, adjusting handle 5, end cap 6, positioning screwn 7, spring 3 is installed in the valve body 4 by valve rod 2, camshaft 1 is fixed on the valve body 4 by two end cap 6, the middle part cam of camshaft 1 is arranged on the upper-end surface of valve rod 2, adjusting handle 5 is arranged on an end of camshaft 1, is provided with positioning screwn 7 on the adjusting handle 5.
It is the valve rod openings of sizes that the utility model comes the upper-lower position of regulating valve stem 2 by rotating cam axle 1, and the rotation of camshaft 1 is rotated by being installed in the outer adjusting handle of valve body 5, and the positioning screwn 7 on the adjusting handle 5 is used for fixing the handwheel position and prevents slippage.It is unadjustable and close the nonadjustable drawback of required force value that the utility model has solved traditional explosion-proof valve openings of sizes, can solve again simultaneously traditional explosion-proof valve and adopt the poor problem of plane sealing sealing, prevented that downstream liquid from flowing out and waste from rent without end, also guaranteed safety simultaneously.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the M-M of Fig. 1 is to sectional view.
Embodiment:
Referring to Fig. 1-2, this embodiment is by the following technical solutions: it comprises camshaft 1, valve rod 2, spring 3, valve body 4, adjusting handle 5, end cap 6, positioning screwn 7, spring 3 is installed in the valve body 4 by valve rod 2, camshaft 1 is fixed on the valve body 4 by two end cap 6, the middle part cam of camshaft 1 is arranged on the upper-end surface of valve rod 2, adjusting handle 5 is arranged on an end of camshaft 1, is provided with positioning screwn 7 on the adjusting handle 5.
It is the valve rod openings of sizes that this embodiment is come the upper-lower position of regulating valve stem 2 by rotating cam axle 1, and the rotation of camshaft 1 is rotated by being installed in the outer adjusting handle of valve body 5, and the positioning screwn 7 on the adjusting handle 5 is used for fixing the handwheel position and prevents slippage.
This embodiment overcomes in the pipeline fluid along journey pressure reduction by spring 3, by camshaft 1 regulating valve stem 2 openings of sizes, when valve both sides P1 end, P2 end pressure difference increase suddenly and make on the valve rod 2 institute stressed during greater than spring force, valve rod 2 can the autoshutdown pipelines, guarantee safety.The utility model is pressed to be installed in and can be prevented on the pressure duct that valve downstream pipelines from bursting from causing that high-pressure liquid leaks outside in a large number.For example be installed on the tap water pipe line, the tap water that can not make the valve upstream after valve downstream pipeline bursting by freezing in winter flows out and wastes from rent without end.
This embodiment two ends are installed on the pipeline by flange, high-pressure liquid flows to and to be P1 → P2, and valve upstream pressure P1 is greater than downstream pressure P2, when valve rod 2 and 4 openings of valve body are very little, up and down both sides at valve rod can form larger pressure difference, thereby make valve rod be easy to close.The adjustable explosion-proof valve of pressure reduction of the present invention can rotate regulating valve stem 2 openings of sizes by valve body 4 outer adjusting handles 5, the eccentric lobe partial rotation of camshaft 1 valve rod 2 openings to upper/lower positions the time are minimum, valve rod 2 openings were maximum when the eccentric lobe partial rotation of camshaft 1 extremely made progress the position, its opening can be adjusted to required size can realize: valve was in open mode when high-pressure liquid was by this valve under normal circumstances, downstream pressure can descend suddenly when the explosion of downstream tube road, owing to valve both sides pressure reduction increases suddenly valve rod is closed.Behind the location positioning of adjusting handle 5, can be fixed by positioning screwn 7.
Claims (2)
1. the adjustable explosion-proof valve of pressure reduction, it is characterized in that it comprises camshaft (1), valve rod (2), spring (3), valve body (4), adjusting handle (5), end cap (6), spring (3) is installed in the valve body (4) by valve rod (2), camshaft (1) is fixed on the valve body (4) by two end cap (6), the middle part cam of camshaft (1) is arranged on the upper-end surface of valve rod (2), and adjusting handle (5) is arranged on an end of camshaft (1).
