The utility model content
The purpose of the utility model is: provide a kind of and can detect the bubble-tight multi-functional airtight pick-up units of plurality of devices such as high pressure vessel, pressure duct.
The technical scheme of the utility model is: a kind of multi-functional airtight pick-up unit; Comprise the loading line that is used to connect the equipment under test air intake opening; Be provided with pressure regulator valve, gas admittance valve and boost gauge successively along the air-flow trend in the loading line; Also comprise the outlet pipe that is used to connect the equipment under test gas outlet; In outlet pipe, be serially connected with the air outlet valve and the tensimeter of giving vent to anger, the entrance point that endpiece and the outlet pipe that is used to connect equipment under test at said loading line is used to connect equipment under test is respectively equipped with pipe joint.
The on the suction side that in loading line, is positioned at pressure regulator valve also is provided with filtrator.
In said loading line, also be provided with safety valve.
The entrance point that is used to connect high-pressure air source at said loading line also is provided with switching ball.
In said outlet pipe, also be provided with flow control valve and flowmeter.
Described loading line and outlet pipe be integrated to be installed on two pipe joints described in the casing and all to be fixed on the sidewall of casing.
In the pipe joint of said loading line and outlet pipe, be sealed and installed with the metal hose that is used to be connected the equipment under test corresponding port respectively.
The multi-functional airtight pick-up unit of the utility model is when the signal piping kind equipment; Be connected loading line and outlet pipe on the equipment under test simultaneously; Loading line fills gases at high pressure in equipment under test, when the pressure equilibrium in loading line and the air inlet pipeline, close gas admittance valve and air outlet valve in loading line and the air inlet pipeline simultaneously; Make the equipment under test sealed at both ends; Thereby the indicating value through observing boost gauge changes the air-tightness that can learn equipment under test, and when the impermeability of detection receptacle kind equipment, only needs loading line is connected with tested container and can detects, and this multi-functional airtight pick-up unit is simple in structure, easy to use; Have wide range of applications, overcome the defective that existing pick-up unit can only detection receptacle kind equipment air-tightness.
Description of drawings
Fig. 1 is the air-channel system figure of the multi-functional airtight pick-up unit specific embodiment of the utility model.
Embodiment
The specific embodiment of the multi-functional airtight pick-up unit of the utility model is as shown in Figure 1, and this multi-functional airtight pick-up unit is made up of loading line and outlet pipe.Wherein, Loading line is used to connect the air intake opening of equipment under test 20; In loading line, be provided with filtrator 1, switching ball 2, pressure regulator valve 3, safety valve 4, gas admittance valve 5 and boost gauge 6 successively, the import of filtrator 1 is used to connect high-pressure air source and gas is filtered; Switching ball 2 is used to open and close pick-up unit; Pressure regulator valve 3 is used for the air pressure of high-pressure air source is adjusted to the specified air pressure of equipment under test 20; Safety valve 4 is used to guarantee the safety of equipment under test 20, prevents that the loading line output pressure is excessive and damages equipment under test 20.In outlet pipe, be provided with the tensimeter 9 of giving vent to anger, air outlet valve 10, flowrate control valve 11 and flowmeter 12 successively along air-flow trend, the tensimeter 9 of giving vent to anger is used for when detecting equipment under test 20 cooperating with boost gauge 6 pressure balance in the observation equipment under test 20; Air outlet valve 10 is used for cooperating the impermeability with control equipment under test 20 to detect with gas admittance valve 5.The entrance point that endpiece and the outlet pipe that is used to connect equipment under test 20 at loading line is used to connect equipment under test 20 is respectively equipped with pipe joint, and through corresponding pipe joint the metal hose 7,8 that is used to connect equipment under test 20 is installed.
When the signal piping kind equipment; Respectively the air intake opening of equipment under test 20 is connected with gas outlet and loading line are corresponding with outlet pipe with metal hose 7,8, the entrance point of loading line is connected on the high-pressure air source, opens switching ball 2, gas admittance valve 5 and air outlet valve 10; By the gas of high-pressure air source output after filtering through filtrator 1; By pressure regulator valve 3 input pressure is transferred to the force value adaptive with equipment under test 20, and be linked into tested device, when the output pressure value of pressure regulator valve 3 surpasses safety valve 4 preset values through metal hose 7; Safety valve 4 is opened release, guarantees device security.Equipment under test 20 air intake opening pressure are by boost gauge 6 monitorings, and equipment under test 20 gas outlet pressure are monitored by the tensimeter 9 of giving vent to anger, simultaneously, and through the gas flow in flowrate control valve 11 and the flowmeter 12 control gas replenishment processes.When the pressure indicating value balance of boost gauge 6 and the tensimeter 9 of giving vent to anger, close the air outlet valve 10 in gas admittance valve 5 and the outlet pipe in the loading line simultaneously, the gas leakage situation of the pressure indicating value monitoring equipment under test 20 through observing boost gauge 6.
