Abstract
The utility model discloses a condenser/evaporator leak detection device, which is characterized in that: the condenser/evaporator leak detection device comprises at least one leak detection line, each leak detection line comprises an inflation valve for inflating detected element, a pressure sensor and a deflation valve are provided between the outlet of the inflation valve and the detected element, the pressure sensor is electrically connected with a pressure digital display meter, the leak detection lines are arranged in parallel, and the inlet of each leak detection line is provided with atotal gas source pressure sensor electrically connected with a total gas source pressure digital display meter. The condenser/evaporator leak detection device can quickly detect the leak of condenseror evaporator.
Description
[technical field]
The utility model relates to a kind of leak test plant.
[background technology]
Prior art is to the single leak detection of the general employing of leak detection of condenser, evaporator, and speed is slow, troublesome poeration.
[summary of the invention]
In view of the problem that present known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of can carry out the leak test plant that rapid and convenient is hunted leak to condenser or evaporator.
For solving the problems of the technologies described above, the utility model takes following technical scheme to finish:
A kind of condenser or evaporator leak test plant, it is characterized in that: described condenser or evaporator leak test plant are provided with at least one leak detection circuit, every the leak detection circuit includes the gas filling valve that measured piece is inflated, be provided with pressure transducer and air release between gas filling valve outlet and the measured piece, pressure transducer and pressure digital displaying meter are electrically connected, each bar leak detection circuit is arranged in parallel, the inflow point of each bar leak detection circuit is provided with a total bleed pressure sensor, and total bleed pressure sensor is electrically connected with total bleed pressure digital displaying meter.Described gas filling valve and air release all adopt solenoid valve.
The bleed pressure of the utility model inflation can accurately be shown by total bleed pressure digital displaying meter, if charge pressure is defective, total bleed pressure digital displaying meter can send alerting signal at once, also have in the setting-up time of measured piece pressurize, if the measured piece internal pressure is lower than setting value, the pressure digital displaying meter can show the underproof signal of product at once, very quick and convenient so hunt leak, simultaneously, the utility model is arranged in parallel many leak detection circuit, can hunt leak to a plurality of measured pieces simultaneously, also just improve leak detection speed greatly; Gas filling valve and air release adopt solenoid valve, can control more easily.
[description of drawings]
The utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model
[embodiment]
Accompanying drawing has been represented the technical solution of the utility model and embodiment, further describes each relevant details and principle of work thereof of embodiment below more in conjunction with the accompanying drawings.
With reference to accompanying drawing 1, this condenser or evaporator leak test plant, be provided with the leak detection circuit that is communicated with total source of the gas of three parallel connections, every leak detection circuit is serially connected with the inflation solenoid valve 3 of two reversal connections each other successively, the outlet of inflation solenoid valve is connected with measured piece 5, be provided with pressure transducer 4 and pressure-releasing electromagnetic valve 7 between inflation electromagnetic valve outlet and the measured piece, pressure transducer is electrically connected with pressure digital displaying meter 6, common inflow point (promptly inflating the import of solenoid valve) at three leak detection circuits is provided with a total bleed pressure sensor 2, and total bleed pressure sensor is electrically connected with total bleed pressure digital displaying meter 1.
The principle of work of this condenser or evaporator leak test plant is such: at first inflation, any one road gas filling valve switch is pressed, gas filling valve is opened this road measured piece inflation (charge pressure: condenser 2.8Mpa, evaporator 1.7Mpa), time can be set (general 10 seconds), if bleed pressure deficiency, total bleed pressure sensor can be given total bleed pressure digital displaying meter alerting signal, and total bleed pressure digital displaying meter can send alerting signal at once; Next product pressurize, in the time of setting, inflation is finished, and then the gas filling valve of two reversal connections is closed, and product begins pressurize, and if inflate defectively, pressure transducer is given the pressure digital displaying meter alert signal of transmitting messages; Detect at last, inflate in qualified back 15 seconds (time can be set), be lower than setting value as the fruit product internal pressure, equipment can show that product is defective by the pressure digital displaying meter, otherwise equipment can show that product is qualified by the pressure digital displaying meter.Detection finishes, and presses air release, venting.
