Background
EVI air-source heat pump engineering has open and closed system two kinds on the market at present, and two kinds of systems lead to the same water pump power down the pipeline discharge different because of the sealed difference of pipeline, and when carrying out the disconnection value measurement on the market at present, mostly be the disconnection value measurement of open flow switch, need carry out the test of disconnection flow value when its flow switch produces, and the water system cost is crossed to the rivers volume of specialty on the market at present.
SUMMERY OF THE UTILITY MODEL
To the above problem, the utility model provides a simple and easy testing arrangement about the open system disconnection value of water flow switch has effectively solved the problem pointed out in the background art.
The utility model adopts the technical proposal that:
the utility model provides a simple and easy testing arrangement about open system disconnection value of water flow switch, includes the open-type water tank to and circulating water pump, first water pipe and the second water pipe that link to each other with the open-type water tank, circulating water pump's play water end is equipped with the third water pipe, third water pipe and first water pipe and second water pipe be linked together respectively, closed water tank on be equipped with moisturizing valve and drain valve, first water pipe on be equipped with water flow switch and first ball valve, first ball valve be located the one end that water flow switch is close to the third water pipe, the second water pipe on be equipped with the third ball valve, the third water pipe on be equipped with the flowmeter, circulating water pump on be equipped with the converter of being connected with the circulating water pump electricity.
The frequency converter is used for adjusting the running frequency of the circulating water pump, so that the water flow is changed, the running frequency of the circulating water pump is increased when the water flow switch is switched off, the rotating speed of the circulating water pump is increased, the running frequency of the circulating water pump is reduced when the water flow switch is switched on, the rotating speed of the circulating water pump is reduced until the water flow switch is just switched off, and the flow value of the flowmeter is read, namely the switching-off value of the water flow switch.
The on-off of the water flow switch can be judged by measuring the resistance value of the lead or the bulb access device through a universal meter, the water flow switch is connected with a circuit when the water pipe is accessed, and the circuit is disconnected when the water pipe is disconnected.
The water replenishing valve is used for replenishing water into the open water tank, and the water draining valve drains water when the device is not used.
Preferably, the first water pipe has a three-way structure at the installation position of the water flow switch.
The first water pipe adopts a three-way structure at the installation position of the water flow switch, so that the water flow switch is convenient to replace, and when the water flow switch is tested in batches, the water flow switch is quickly replaced.
Preferably, the flow meter is a mechanical flow meter or an electronic flow meter.
The flowmeter is used for monitoring water flow, and flowmeters with different accuracies are selected during actual detection according to requirements.
The utility model discloses an on-off condition of water flow switch comes the regulation to the converter to change discharge, read corresponding flow value when water flow switch reaches the critical state of disconnection, can detect water flow switch's disconnection value, the utility model discloses simple structure, convenient operation.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the following detailed description of specific embodiments and the accompanying drawings.
As shown in fig. 1, the utility model provides a simple and easy testing arrangement about open system disconnection value of water flow switch, including open water tank 1 to and circulating water pump 2, first water pipe 3 and the second water pipe 4 that link to each other with open water tank 1, circulating water pump 2's play water end is equipped with third water pipe 5, third water pipe 5 be linked together respectively with first water pipe 3 and second water pipe 4, open water tank 1 on be equipped with moisturizing valve 6 and drain valve 7, first water pipe 3 on be equipped with water flow switch 8 and first ball valve 9, first ball valve 9 be located the one end that water flow switch 8 is close to third water pipe 5, second water pipe 4 on be equipped with third ball valve 11, third water pipe 5 on be equipped with flowmeter 12, circulating water pump 2 on be equipped with the converter 13 of being connected with circulating water pump 2 electricity.
The first water pipe 3 is of a three-way structure at the installation position of the water flow switch 8.
The flow meter 12 is a mechanical flow meter or an electronic flow meter.
The utility model discloses a theory of operation:
when detection is carried out, the second ball valve 11 and the drain valve 7 are closed, the first ball valve 9 is opened, the running frequency of the circulating water pump 2 is adjusted through the frequency converter 13, so that the water flow is adjusted, the running frequency of the circulating water pump 2 is increased when the water flow switch 8 is switched off, the rotating speed of the circulating water pump 2 is increased, the running frequency of the circulating water pump 2 is reduced when the water flow switch 8 is switched on, the rotating speed of the circulating water pump 2 is reduced until the water flow switch 8 is just switched off, and the flow value of the flow meter 12 is read, namely the switching-off value of the water flow switch 8.
When examining the water flow switch in batches, need to change the water flow switch and examine, the concrete change step of water flow switch is: open second ball valve 11, close first ball valve 9, the water that circulating water pump 2 flows out gets back to open-type water tank 1 after third water pipe 5, second water pipe 4 in proper order, does not have rivers on first water pipe 3, can carry out the change of rivers switch 8 this moment, and after the change is accomplished, close second ball valve 11, open first ball valve 9 and can inspect.
When the water flow switch is tested in batches, the water flow switch can be replaced without stopping the machine, and the testing efficiency is high.
Finally, it should be noted that the above-mentioned embodiments are only specific embodiments of the present invention. Obviously, the present invention is not limited to the above embodiments, and many modifications are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the invention should be considered as within the scope of the invention.
