Abstract
The utility model relates to a water source constant pressure control device for checking, comprising a water pump and a water tank. The device is characterized by further comprising an upright pipe, a horizontal main pipe and a plurality of thin pipes for checking and an overflow pipe; the upright pipe is opened upwards, and the other end of the upright pipe is connected with the horizontal main pipe; the plurality of thin pipes for checking are connected with the horizontal main pipe in a horizontal manner; the horizontal pipe section of the overflow pipe is connected with the upright pipe; the potential difference from the horizontal pipe section of the overflow pipe to the horizontal main pipe is 10 m; the water outlet of the overflow pipe is connected with the water tank; the inlet end of the water pump is connected with the water tank; and the outlet end of the water pump is connected with an area among the pipe joints of the overflow pipe, the horizontal main pipe and the upright pipe. The water source constant pressure control device for checking has the following advantages: the flow capacity of the water pump is larger than the sum of the flow capacity for checking, and the potential difference from the overflow pipe to the horizontal main pipe is 10 m; therefore, the pressures of the water outlets of the thin pipes for checking keep to be a constant value of 0.1 MPa without pressure oscillation under the condition that the water source is uninterrupted, and the quality of product detection is ensured.
Description
Technical field:
The utility model relates to the test of a kind of equipment or member, especially relates to a kind of verification water source constant voltage control device.
Background technology:
Need in the water meter production performance to water meter is carried out verification, whether qualified to judge the water meter of being produced.And verification just seems very important with the pressure control at water source, especially to the detection of the low discharge detection as boundary flow and minimum flow, if the pressure at water source fluctuates, then can exert an influence to testing result.In the water meter industry, generally adopt two kinds of methods at present: elevated tank method and tube of pressure-stabilizing method.The principle of work of elevated tank method is that water is risen in the water tank of certain altitude, utilizes the height of water tank to keep the stable of hydraulic pressure.The height of water tank middle water level is controlled by level gauge, and system's meeting automatic water supplement can stop moisturizing when arriving designated water level when water level is lower than designated water level, so just have the difference in height of a water level, be pressure differential, make the water source have certain pressure surge, detect and to produce error.The tube of pressure-stabilizing method is to adopt variable frequency pump that water is injected in the airtight water drum, and sets a force value, guarantees the pressure stability that tube is interior with the frequency change of pump.The transmission of pressure signal has hysteresis phenomenon because the fluctuations in discharge of test water meter is big, therefore in use, still has pressure surge, influences test result.
The utility model content:
The purpose of this utility model is verification that a kind of simple in structure, no pressure surge is provided at the prior art weak point with water source constant voltage control device.
The purpose of this utility model is to realize by following measure: a kind of verification includes water pump, pond with water source constant voltage control device, it is characterized in that, also has: standpipe, horizontal house steward, some verifications tubule, run-down pipe; Described standpipe opening up, the standpipe other end is connected with horizontal house steward, some verifications are connected with the horizontal and horizontal house steward of tubule, the horizontal pipeline section of run-down pipe is connected with standpipe, horizontal pipeline section of run-down pipe and horizontal house steward's potential difference is 10 meters, run-down pipe water delivering orifice water-accepting tank, described water pump entrance point water-accepting tank, pump outlet are connected pipe that run-down pipe, horizontal house steward be connected with the standpipe zone between connecing.
Compared with prior art, adopted the verification water source constant voltage control device that the utility model proposes, has following advantage: because the flow of water pump is greater than the summation of verification with discharge, run-down pipe and horizontal house steward's potential difference is 10 meters, so remaining verification under the continual situation in water source is that 0.1Mpa is invariable with the pressure of tubule water delivering orifice, the quality that product detects has been guaranteed in no pressure surge.
Description of drawings:
Fig. 1 is an example structure synoptic diagram that the utility model proposes.
Embodiment:
Below in conjunction with accompanying drawing embodiment is elaborated: at an embodiment of the present utility model shown in Figure 1.Among the figure, a kind of verification includes water pump 4, pond 5, standpipe 1, horizontal house steward 2, some verifications tubule 6, run-down pipe 3 with water source constant voltage control device.Described standpipe 1 opening up, the standpipe other end is connected with horizontal house steward 2, some verifications are connected with tubule 6 horizontal and horizontal house stewards 2, run-down pipe 3 horizontal pipeline sections are connected with standpipe 1, run-down pipe 3 horizontal pipeline sections and horizontal house steward's 2 potential difference is 10 meters, run-down pipe 3 water delivering orifice water-accepting tanks 5, described water pump 4 entrance point water-accepting tanks 5, water pump 5 endpiece are connected pipe that run-down pipe 3, horizontal house steward 2 be connected with standpipe 1 zone between connecing.
The utility model is work like this: the flow of water pump is greater than the summation of verification with the tubule water consumption, standpipe, horizontal house steward's sectional area is greater than the sectional area sum of verification with tubule simultaneously, the standpipe opening communicates with atmosphere, after the running of pump interrupted water, run-down pipe and horizontal house steward's potential difference is 10 meters, so under the effect of run-down pipe, it is invariable that verification remains at 0.1Mpa with the top hole pressure of tubule.
Embodiment of the present utility model has been described above in conjunction with the accompanying drawings; the structure that embodiment provides does not constitute restriction of the present utility model, and those skilled in the art make various distortion within the scope of the appended claims or revise all in protection domain in this area.
