Abstract
The utility model discloses a water supply pressure stabilizer for a dynamometer, which comprises a pressure reducing valve, a pressure stabilizing bucket and a relief valve; the pressure reducing valve, the pressure stabilizing bucket and the relief valve are connected sequentially and serially; the water outlet of the pressure stabilizing bucket is communicated with the dynamometer through a water feeding pipe; the water inlet of the pressure reducing valve is connected with a water pump; the water outlet of the relief valve is connected with a low level water tank through the water feeding pipe; the backwater port of the dynamometer is connected with the low level water tank through the water feeding pipe. The water supply pressure stabilizer for the dynamometer has the advantages of small space occupation, simple structure, applicable functions and convenient operation.
Description
Technical field
The utility model relates to a kind of dynamometer machine water-supply voltage-stabilizing device, and a kind of stable-pressure device of stablizing hydraulic pressure that provides for the water turbulence dynamometer machine is provided.
Background technology
As everyone knows, in the water turbulence dynamometer machine water system of using at present, be to adopt elevated tank to come to carry out voltage stabilizing to supplying with water.In this system, the water that water pump is taken out is at first delivered in the elevated tank, and elevated tank has run-down pipe that unnecessary current are got back to low pool, and under the situation of pump interrupted water work, the water of elevated tank keeps full water always like this.Elevated tank feedwater eddy current dynamometer supplies water, thereby then the pressure of supply water of dynamometer machine obtains to stablize hydraulic pressure because of elevated tank keeps full water, and such device takies than large space.But in the less threst stand in some spaces, can't use this mode of the elevated tank eddy current dynamometer that feeds water to supply water.
Summary of the invention
Technical problem to be solved in the utility model is the defective that overcomes prior art, and a kind of dynamometer machine water-supply voltage-stabilizing device that large space just can be realized voltage stabilizing function very much that do not need to take is provided.
For solving the problems of the technologies described above, the utility model provides a kind of dynamometer machine water-supply voltage-stabilizing device, comprise reduction valve, voltage stabilizing bucket, blowdown valve, described reduction valve, voltage stabilizing bucket, blowdown valve are connected successively by feed pipe, and the water delivering orifice of described voltage stabilizing bucket is connected with dynamometer machine by feed pipe.
The water inlet of described reduction valve links to each other with suction pump; The water delivering orifice of described blowdown valve connects low pool by feed pipe; The water return outlet of described dynamometer machine also connects low pool by feed pipe.
Owing to adopt above-mentioned technical scheme, the utlity model has following beneficial effect:
Adopt the utility model to replace traditional elevated tank, can dwindle the volume of whole hydraulic control device widely, simple in structure, function is suitable for, and is easy and simple to handle, do not settling the place of elevated tank especially suitable than large space.
Description of drawings
Fig. 1 is the schematic diagram of the utility model dynamometer machine water-supply voltage-stabilizing device.
Mark the following drawings mark thereon in conjunction with the accompanying drawings:
The 1-reduction valve, 2-voltage stabilizing bucket, 3-blowdown valve, 4-dynamometer machine.
Embodiment
Below in conjunction with accompanying drawing embodiment is illustrated:
As shown in Figure 1, the utility model dynamometer machine water-supply voltage-stabilizing device comprises reduction valve 1, voltage stabilizing bucket 2, blowdown valve 3, and reduction valve 1, voltage stabilizing bucket 2, blowdown valve 3 are connected successively by feed pipe, and the water delivering orifice of voltage stabilizing bucket 2 is connected with dynamometer machine 4 by feed pipe.
The water inlet of reduction valve 1 links to each other with suction pump; The water delivering orifice of blowdown valve 3 connects low pool by feed pipe; The water return outlet of dynamometer machine 4 also connects low pool by feed pipe.
The water that suction pump is taken out is at first adjusted pressure through reduction valve 1, the voltage stabilizing bucket 2 that connects behind the reduction valve 1 is further stablized hydraulic pressure, water one road after stable is supplied with 4 uses of water turbulence dynamometer machine, another road connects a blowdown valve 3, too high pressure is let out back low pool, and the backwater of dynamometer machine 4 is also got back to low pool.Form a round-robin water scheme like this.The pressure of supply water of dynamometer machine 4 is regulated jointly by reduction valve 1 and blowdown valve 3.
Can use the utility model to come that hydraulic pressure is carried out voltage stabilizing on the water supply line of water turbulence dynamometer machine 4 handles.The water that suction pump is come at first passes through reduction valve 1, adjust the size of pressure regulator valve according to actual needs, thereby reach the purpose of adjusting hydraulic pressure, be that voltage stabilizing bucket 2 is further stablized hydraulic pressure then, feedwater eddy current dynamometer 4 supplies water in the middle of the voltage stabilizing bucket, voltage stabilizing bucket 2 back connect blowdown valve 3, and too high hydraulic pressure branch is flow back in the low flush tank.The pressure of supply water of water turbulence dynamometer machine 4 is regulated in the pressure of supply water scope of suction pump by reduction valve 1 and blowdown valve 3, like this, adopt the utility model to replace the mode of traditional water turbulence dynamometer machine high-level tank water, can reduce elevated tank, dwindle the volume of total system, be not suitable for the frame elevated tank and do not have the place of large space installation elevated tank especially suitable at some.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this instructions has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
Claims (2)
1, a kind of dynamometer machine water-supply voltage-stabilizing device is characterized in that: comprise reduction valve, voltage stabilizing bucket, blowdown valve, described reduction valve, voltage stabilizing bucket, blowdown valve are connected successively by feed pipe, and the water delivering orifice of described voltage stabilizing bucket is connected with dynamometer machine by feed pipe.
2, dynamometer machine water-supply voltage-stabilizing device according to claim 1, it is characterized in that: the water inlet of described reduction valve links to each other with suction pump; The water delivering orifice of described blowdown valve connects low pool by feed pipe; The water return outlet of described dynamometer machine also connects low pool by feed pipe.
