Summary of the invention
The purpose of the utility model is to overcome the defective of prior art and a kind of device for measuring length of pipeline that is used to be full of the incompressible fluid pipeline is provided; For practical applications provides duct length data accurately; Especially solve the problem of earth source heat pump pipe laying linear measure longimetry, test and detect actual construction length for ground heat exchanger accurate data are provided.
The purpose of the utility model is achieved in that
A kind of device for measuring length of pipeline that is used to be full of the incompressible fluid pipeline of the utility model; Comprise pressure wave signal acquisition and analysis instrument, pressure wave signal collection lead, pressure wave transmitter, pressure wave receptacle, conduit entrance joint and pipe outlet joint; Wherein
Said pressure wave signal acquisition and analysis instrument is connected with said pressure wave receptacle with said pressure wave transmitter respectively through pressure wave signal collection lead and links to each other;
Said conduit entrance joint is located on the said pressure wave transmitter;
Said pipe outlet joint is located on the said pressure wave receptacle.
Said conduit entrance joint is connected with the import and export of tested pipeline respectively with the pipe outlet joint.
Said pressure wave transmitter can pressurize to the liquid in the pipeline, can produce and send dissimilar pressure waves, for example pulsed pressure wave, sine pressure wave.
Said pressure wave receptacle can be rapidly, the situation of change of pipelines top hole pressure exactly, can be the higher and willing various pressure probes of sensitivity.
Said pressure wave signal acquisition and analysis instrument is gathered each signal of pressure wave transmitter and pressure wave receptacle constantly of lead continuous acquisition through pressure wave signal, and can utilize the basic parameter of the signal that collects and user's setting automatically to calculate the length of pipeline.
The utility model device is particularly useful for but is not limited to earth source heat pump pipe laying measurement of length.
The beneficial effect of the utility model is: the device for measuring length of pipeline that the utility model is used to be full of the incompressible fluid pipeline is through being provided with the pressure wave transmitter in conduit entrance; At pipe outlet the pressure wave receptacle is set and receives the pressure wave that the pressure wave transmitter sends; According to sending and receiving the mistiming of pressure wave or the physical length that phase differential calculates pipeline, measuring speed and measuring accuracy that duct length is measured have been improved.
Simultaneously, when the utility model device for measuring length of pipeline is used for the linear measure longimetry of earth source heat pump pipe laying, do not receive the restriction of pipe laying form, can measuring vertical the buried length of tube of single U type, flatly pipe laying length or other forms of single buried length of tube.
Description of drawings
