Abstract

Tube Sheet of Heat Exchanger pipeline leakage stopping pick-up unit, heat interchanger (2) has into refrigerant pipe (21) and goes out refrigerant pipe (22), source of the gas gas cylinder (1) by pipeline with enter refrigerant pipe (21) and connect mutually, go out refrigerant pipe (22) to be connected mutually by pipeline and restriction device (5), restriction device (5) be throttling valve, orifice plate or kapillary; Source of the gas gas cylinder (1) with enter on pipeline that refrigerant pipe (21) connects mutually constant pressure valve (3) and pressure maintaining valve (4) are installed, restriction device (5) with go out on pipeline that refrigerant pipe (22) connects mutually the first pressure transducer (6) is installed.Whether it can detect heat exchanger tube and whether there occurs blocking after welding, also can detect heat exchanger tube simultaneously and leak gas after welding, thus unnecessarily power consumption is excessive to avoid air-conditioning system.

Description

Tube Sheet of Heat Exchanger pipeline leakage stopping pick-up unit
Technical field:
The utility model relates to air-conditioning technical field, more specifically to air-condition heat exchanger pipeline leaking stoppage pick-up unit.
Background technology:
As shown in Figure 1, existing air-condition heat exchanger includes copper pipe A1, fin A2, enters refrigerant pipe A3 and go out refrigerant pipe A4, copper pipe A1, enter refrigerant pipe A3 and go out refrigerant pipe A4 and all weld together with header A5, in welding process, can occur unavoidably to be formed when copper pipe A1 welds with header A5 to block or weld and not in placely produce the phenomenon of leaking gas.But general air conditioning system maker does not have heat exchanger pipeline and whether there occurs blocking when welding and detect, if this just causes place's copper pipe when welding and header blocks, then compressor is just needed to add high-power, flow through refrigerant from other unplugged pipeline, cause air-conditioning consume energy excessive.
Utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and a kind of Tube Sheet of Heat Exchanger pipeline leakage stopping pick-up unit is provided, it can detect heat exchanger tube and whether there occurs blocking after welding, also can detect heat exchanger tube whether to leak gas after welding, thus unnecessarily power consumption is excessive to avoid air-conditioning system simultaneously.
Technology solution of the present utility model is as follows:
Tube Sheet of Heat Exchanger pipeline leakage stopping pick-up unit, comprise the heat interchanger after source of the gas gas cylinder and welded pipe line, heat interchanger has into refrigerant pipe and goes out refrigerant pipe, source of the gas gas cylinder by pipeline with enter refrigerant pipe and connect mutually, go out refrigerant pipe to be connected mutually by pipeline and restriction device, restriction device is throttling valve, orifice plate or kapillary etc., but is not limited only to this;
Source of the gas gas cylinder with enter on pipeline that refrigerant pipe connects mutually constant pressure valve and pressure maintaining valve are installed, restriction device with go out on pipeline that refrigerant pipe connects mutually the first pressure transducer is installed.
Described source of the gas gas cylinder with enter on pipeline that refrigerant pipe connects mutually the second pressure transducer is installed.
Described source of the gas gas cylinder with enter pipeline and restriction device that refrigerant pipe connects mutually and go out on pipeline that refrigerant pipe connects mutually differential manometer is installed.
The beneficial effects of the utility model are:
Whether it can detect heat exchanger tube and whether there occurs blocking after welding, also can detect heat exchanger tube simultaneously and leak gas after welding, thus unnecessarily power consumption is excessive to avoid air-conditioning system.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of prior art;
Fig. 2 is the structural representation of embodiment 1;
Fig. 3 is the structural representation of embodiment 2;
Fig. 4 is the structural representation of embodiment 3.
In figure: 1, source of the gas gas cylinder; 2, heat interchanger; 21, refrigerant pipe is entered; 22, refrigerant pipe is gone out; 3, constant pressure valve; 4, pressure maintaining valve; 5, restriction device; 6, the first pressure transducer; 7, the second pressure transducer; 8, differential manometer.
Embodiment:
Embodiment: as shown in Figure 2, Tube Sheet of Heat Exchanger pipeline leakage stopping pick-up unit, comprise the heat interchanger 2 after source of the gas gas cylinder 1 and welded pipe line, heat interchanger 2 has into refrigerant pipe 21 and goes out refrigerant pipe 22, source of the gas gas cylinder 1 by pipeline with enter refrigerant pipe 21 and connect mutually, go out refrigerant pipe 22 to be connected mutually by pipeline and restriction device 5, restriction device 5 is throttling valve, orifice plate or kapillary;
Source of the gas gas cylinder 1 with enter on pipeline that refrigerant pipe 21 connects mutually constant pressure valve 3 and pressure maintaining valve 4 are installed, restriction device 5 with go out on pipeline that refrigerant pipe 22 connects mutually the first pressure transducer 6 is installed.
Embodiment 2, as shown in Figure 3, described source of the gas gas cylinder 1 with enter on pipeline that refrigerant pipe 21 connects mutually the second pressure transducer 7 is installed.All the other are with embodiment 1.
Embodiment 3, as shown in Figure 4, described source of the gas gas cylinder 1 with enter pipeline that refrigerant pipe 21 connects mutually and restriction device 5 and go out on pipeline that refrigerant pipe 22 connects mutually differential manometer 8 is installed.
Principle of work: the principle of work of embodiment 1, the normal value of the first pressure transducer 6 when by experiment repeatedly, we detect that if the pipeline of heat interchanger does not block in advance, and pipeline block after the detected value of heat interchanger first pressure transducer 6 can have a difference with normal value, if higher than this difference in certain limit, then illustrate there is line clogging, if lower than, be then gas leakage.The force value of the detected value of the first pressure transducer 6 and pressure maintaining valve also can compare and draw difference by embodiment 1, thus learns whether the pipeline of heat interchanger has blocking.
Embodiment 2 is that the difference of detected value by observing the first pressure transducer 6 and the second pressure transducer 7 learns whether the pipeline of heat interchanger has blocking.
Embodiment 3 is directly observed source of the gas gas cylinder 1 by differential manometer and enters pipeline that refrigerant pipe 21 connects mutually and with the pressure differential going out the pipeline that refrigerant pipe 22 connects mutually, restriction device 5 learns whether the pipeline of heat interchanger has blocking.
