The utility model discloses a benefit on satisfying equal detection effect's basis has: one, green practices thrift electric power, water conservancy equal energy source, two, detection effect is more accurate, and work efficiency is higher, reduces personnel's cost, three, reduce the bad outflow of leakage, reduce the after sales maintenance expense.
Description
Technical field
The utility model relates to a kind of car air conditioner and detects auxiliary device, especially relates to a kind of air-conditioning line heater detection tabs.
Background technique
Car air conditioner is the product of car comfort development, and whether the leakage of air-conditioning core body is directly connected to car air conditioner and can normally works, and traditional detection tabs efficiency is low, error large, can not meet modern production requirement.Original detection tabs can not meet accurate, the high efficiency that detect heater and leak, and therefore, design one can be more accurate, the detection tabs that working efficiency is higher.
Model utility content
The utility model provides a kind of air-conditioning line heater detection tabs, and object is that solution can detect whether heater leaks simply, fast, accurately.By detecting the pressure reduction △ P of both heater and standard piece, combine the parameters such as the input pressure of gas, flow and time again through internal computer analysis and carry out integral operation, directly can draw leakage rate data (leakage rate conventional unit is mL/min), improve accuracy.Its technological scheme is as described below:
A kind of air-conditioning line heater detection tabs, comprise the core body inlet hole being connected with measured piece and being connected, described core body inlet hole passes slip upper cylinder body, cylinder lower cylinder body successively, connects guide pillar, rubber ring, conical compression block from measured piece side, it is the circular hose nozzle of heater outside described rubber ring, and be connected with cylinder lower cylinder body by rubber ring block, described slip upper cylinder body also and between cylinder lower cylinder body forms gas storage chamber in cylinder lower cylinder body, measured piece the same side is provided with suction port, and described suction port enters gas storage chamber for transmitting pressurized air.
Upper cylinder body seal ring is provided with, for sealing gas storage chamber between described slip upper cylinder body and cylinder lower cylinder body.
Lower cylinder body seal ring is provided with, for sealing gas storage chamber between described cylinder lower cylinder body and rubber ring block.
Described connection guide pillar is fixedly connected with conical compression block.
Described cylinder lower cylinder body is fixedly connected with rubber ring block.
The benefit of this model utility on the basis meeting equal Detection results be a little: one, environmental protection, conservation of power, water conservancy equal energy source; Two, Detection results is more accurate, and working efficiency is higher, reduces personnel cost; Three, reduce the bad outflow of leakage, reduce after-sales service expense.
Accompanying drawing explanation
Fig. 1 is the structural representation of described air-conditioning line heater detection tabs inflated condition;
Fig. 2 is the structural representation of described air-conditioning line heater detection tabs sealing state;
Fig. 3 is that heater product adopts differential pressure method to carry out the fundamental diagram of Leak testtion.
Embodiment
As Fig. 1, air-conditioning line heater detection tabs shown in Fig. 2, a kind of air-conditioning line heater detection tabs, comprise the core body inlet hole 12 being connected with measured piece and being connected, described core body inlet hole 12 passes slip upper cylinder body 7 successively from measured piece side, cylinder lower cylinder body 6, connect guide pillar 5, rubber ring 3, conical compression block 2, it is the circular hose nozzle 1 of heater outside described rubber ring 3, and be connected with cylinder lower cylinder body 6 by rubber ring block 4, described slip upper cylinder body 7 also and between cylinder lower cylinder body 6 forms gas storage chamber 9 in cylinder lower cylinder body 6, measured piece the same side is provided with suction port 8, described suction port 8 enters gas storage chamber 9 for transmitting pressurized air.Upper cylinder body seal ring 10 is provided with, for sealing gas storage chamber 9 between described slip upper cylinder body 7 and cylinder lower cylinder body 6.Lower cylinder body seal ring 11 is provided with, for sealing gas storage chamber 9 between described cylinder lower cylinder body 6 and rubber ring block 4.Described connection guide pillar 5 is fixedly connected with conical compression block 2.Described cylinder lower cylinder body 6 is fixedly connected with rubber ring block 4.
Inflated condition as shown in Figure 1, after detecting the circular hose nozzle 1 of chuck insertion heater, pressurized air is inflated the standard piece of product and measured piece simultaneously, and its mouth of pipe is sealed, core body inlet hole 12 is connected with measured piece, when being inflated to setting pressure, close equilibrium valve the two is separated, the pressure reduction △ P of both measurements, the pressure of input gas is combined again through internal computer analysis, the parameter such as flow and time carries out integral operation, draw leakage rate data (leakage rate conventional unit is mL/min), finally the leakage rate data drawn and setting value are in advance made comparisons, according to certain deviate, judge the qualified and defective of product, and output signal.After measurement terminates, the pressurized gas in both being discharged by outlet valve, this completes a pressure testing circulation.
Sealing state as shown in Figure 2, after detecting the circular hose nozzle 1 of chuck insertion heater, contracting air enters gas storage chamber 9 by suction port 8, produce pressure promotion slip upper cylinder body 7 and move (gas storage chamber 9 forms sealing state by the rubber ring 10,11 on upper and lower cylinder body), the connection guide pillar 5 be connected with upper cylinder body and connected conical compression block 2 are pulled and moves upward, maintain static due to lower cylinder body 6 and rubber ring block 4 thus cause rubber ring 3 to be sealed by hose nozzle 1 by compression-expansion.
Heater product adopts differential pressure method to carry out Leak testtion, as shown in Figure 3, be provided with differential pressure pickup 22 as between the heater 30 of measured piece and standard piece 40, and be all connected with compensation flap 22, and inflation is completed by gas charging valve 24, gas charging valve 24 front end is provided with modulating valve 23.Pressurized gas in both discharges is completed by outlet valve 25, and compensation flap 22 place is provided with pressure transducer 21.Its detecting method is when detecting heater 30, inflation is carried out with sealing simultaneously, simultaneously inflation inflates heater 30 and standard piece 40 inside, when being filled with air to the pressure set, pressurize a period of time, allowing heater 30, identical with the air pressure of standard piece 40 (standard piece 40 is identical or approximate with the gas volume of tested heater, to check the accuracy of numerical value under ensureing equivalent environment), at pressurize gas during this period of time, be sealed into gas port continuous charge, ensure that sealing is not normally revealed, after pressurize receives, close the compensation flap 22 of heater 30 suction port and standard piece 40, the pressure reduction △ P of both measurements, the pressure of input gas is combined again through internal computer analysis, the parameter such as flow and time carries out integral operation, draw leakage rate data (leakage rate conventional unit is mL/min).
