Embodiment
To make the purpose, technical scheme and advantage of the application clearer, below in conjunction with the accompanying drawing in embodiment, to reality The technical scheme applied in example is clearly and completely described, it is clear that described embodiment is only that the application part is implemented Example, rather than whole embodiments.Based on the embodiment provided, those of ordinary skill in the art are not before creative work is made The every other embodiment obtained is put, belongs to the scope of the application protection.
In the description of the present application, it is to be understood that the orientation or position relationship of the instruction such as term " on ", " under " are base In orientation shown in the drawings or position relationship, it is for only for ease of description the application and simplifies description, rather than indicate or imply Signified device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this The limitation of application.
In the description of the present application, term " first ", " second " etc. be only used for describe purpose, and it is not intended that instruction or Imply relative importance or the implicit quantity for indicating indicated technical characteristic.
Double discharge structures are collected in a kind of micro- leakage, and comprising valve body 1, seal, the first valve pocket 11, the second valve are provided with valve body Chamber 12, it is characterised in that:Exhaust passage is provided with the valve body 1, first valve pocket 11 is with being arranged in the first valve pocket 11 Valve handle 2 between be provided with the first air collecting chamber 111, between second valve pocket 12 and the sealing shroud 32 being arranged in the second valve pocket 12 Provided with the second air collecting chamber 121, the intake interface 19 forms the 3rd collection in the root of inlet suction port 19 after being closely assembled with gas source connector 7 Air cavity 13, second air collecting chamber 121 are connected by second exhaust passage 17 with second exhaust exit passageway 18, first gas collection Chamber 111 is connected by central exhaust duct 14 with the 3rd air collecting chamber 13, is then gone out by first exhaust passage 15 with first exhaust Mouth passage 16 connects.
The specific course of work:
First, corrugated flexible hose is vented in first, second exhaust gas outlet pathway 16,18 end A, B mouth connections, ripple will be vented The line flexible pipe other end draws restricted clearance.
The first end 321 of sealing shroud 32 is provided with screw thread, is connected with the inner thread of the second valve pocket 12, first end screw tip is set The second sealing ring 5 is equipped with, the second sealing ring 5 and the inwall of the second valve pocket 12, which are formed, to be sealed, and the second sealing ring 5 is provided with second Air collecting chamber 121, it is pressure-bearing side in face of the direction of the second valve element 31 for second seal 5, gas can pass through first end 321 Threaded connection between clearance leakage to second seal 5, if the poor sealing of second seal 5, the gas of leakage can enter Enter the second air collecting chamber 121, leak atmospheric pressure superatmospheric, gas will be exported logical by second exhaust passage 17 and second exhaust Discharge in air in road 18.
Valve handle 2 is connected with the inner thread of the first valve pocket 11, and valve handle 2 is provided with annular groove, ring close to the axle portion of valve element 21 First sealing ring 4 is installed in connected in star, the compression end of the first sealing ring 4 is provided with the first air collecting chamber 111, it is close for first For seal 4, the direction of the first valve element 21 is pressure-bearing side, if the poor sealing of the first sealing ring 4 can produce leakage, gas enters first Air collecting chamber 111, the 3rd air collecting chamber 13 is then imported by central exhaust duct.
Gas source connector 7 in the root of inlet union 19 after the tight fit of inlet union 19 with foring the 3rd air collecting chamber 13, import The gases at high pressure at place can be from the clearance leakage between the screw thread of inlet union 19 and gas source connector 7 to the 3rd air collecting chamber 13, then Drained into by first exhaust passage 15 and first exhaust exit passageway 16 in air.
