By adopting technique scheme, first test set 1 and the second test set 2 all adopt driving member to drive corresponding venting part action, eliminate artificial trouble complicated move venting part, and adopt the driving member of machinery to replace manual working, work precision and accuracy higher; At two ports of suction valve, all test set is set, eliminates the artificial trouble that air inlet port or the air outlet of suction valve are inflated that moved around by gas-filled pump; Moreover the suction valve detection of any model is placed at the first driving member 12 and the second driving member 22, the attribute that can promote of driving member can both be utilized to detect preferably; Be that the second test set 2 arranges sealed piece 23, its main purpose prevents gas from revealing around the second gas detector 21 thus causes test inaccurate; One in the first test set 1 and the second test set 2 arranges sealed piece 23, and the mouth of giving vent to anger when mainly the test set correspondence being provided with sealed piece 23 being detected detects, and effectively prevents gas leakage from affecting testing result; Sealed piece 23 slippage is set on the second output terminal 221, and the port that can seal its correspondence when needing to give vent to anger effectively prevents from revealing; The port that sealing group 3 is used for sealing up suction valve connected electromagnetic valve is set, effectively prevents the situation occurring gas leakage in suction valve testing process, thus effectively ensure that the reliability of suction valve testing result.It should be noted that in this programme and only have the second test set 2 that sealed piece 23 is set, its main purpose reveals to prevent, but the second test set 2 and the second test set 2 all can arrange sealed piece 23 and effectively prevent from ventilation and give vent to anger not revealing in the process of practical application; Therefore the present embodiment just proposes a kind of most basic scheme preventing revealing.First venting part 11 selects the gas-filled pump of general gas-powered, and the air outlet connecting hose of gas-filled pump, then connects the output terminal of flexible pipe with corresponding test set.
Described first driving member 12 and the second driving member 22 are cylinder, and described first venting part 11 is located at the end of the first output terminal 121, and described first gas detector 13 and the second gas detector 21 are stationary gas detecting head.First driving member 12 and the second driving member 22 are all chosen as cylinder, utilize cylinder quick acting and free of contamination advantage, frequently can detect suction valve; The stationary gas detecting head of GT100 series all selected by first gas detector 13 and the second gas detector 21, mainly because described first gas detector 13 and the second gas detector 21 include detecting head 132,212 and warning device 131,211, detecting head 132, the port that the test set belonging to 212 correspondences detects is arranged, described warning device 131,211 and detecting head 132,212 couple.Detecting head 132,212 are mainly sent by sensor and change and form, and are arranged on the detection place being similar to the places such as valve port; Warning device 131,211 mainly comprise power supply, circuit and displaying alarm 131,211 compositions, this composition is as secondary meter, usually be integrally arranged on safer position, be convenient for people to observation, because stationary gas detecting head is prior art herein, the relation that couples of its various piece, known by person of ordinary skill in the field, is no longer carefully said herein.
Described sealed piece 23 comprises fixed tray 231, at least two connecting rods 232 and slippage are sheathed on the supporting disk 233 of the second output terminal 221, described two connecting rods 232 all connect supporting disk 233 and fixed tray 231 in two ends respectively, and described supporting disk 233 and fixed tray 231 are arranged with one heart, one end of described connecting rod supporting disk 233 dorsad is convexly equipped with the inflation platform 235 penetrating gas outlet valve port for transition, described fixed tray 231 offers the putting hole concentric with the second output terminal 221, described inflation platform 235 offers vent hole 234, described putting hole and vent hole 234 are arranged with one heart and the internal diameter of this vent hole 234 is less than the internal diameter of putting hole.It is convenient in the slippage on the second output terminal 221 of whole sealed piece 23 that fixed tray 231 is set, at least two connecting rods 232 are set, play the effect fixing and be connected and fixed dish 231 and supporting disk 233, supporting disk 233 and fixed tray 231 are arranged with one heart, corresponding air-filled pore and putting hole are also arrange with one heart, and so the connecting rod 232 of at least two can be connected and fixed dish 231 and supporting disk 233(can only adopt two connecting rods 232 as shown in FIG. to be connected and fixed dish 231 and supporting disk 233 in the mode around air-filled pore circle distribution); One end projection inflation platform 235 of air-filled pore supporting disk 233 dorsad, what preferably arranged by inflation platform 235 needs the internal diameter size of the port detected adaptive with the second test set 2, so just can be very adaptive by inflation platform 235 penetrate in the port of gas charging valve, effectively prevent the leakage of gas, the internal diameter being less than putting hole of the internal diameter setting of further vent hole 234, also just further can prevent gas from revealing before detecting head, effectively ensure that the reliability of suction valve testing result.
The threaded one end of described second output terminal 221 relative support dish 233 is connected with stop nut, and this stop nut is in the side of the relative fixed tray 231 of supporting disk 233.Stop nut is threaded with the second output terminal 221, and the circumcircle diameter of pharmacy stop nut is greater than the internal diameter that supporting disk 233 is set in the hole on the second output terminal 221, just can effectively prevent supporting disk 233 from departing from the connection with the second output terminal 221.
When detection operation, supporting disk 233 slippage is allowed to be connected on the second output terminal 221, second output terminal 221 drives sealed piece 23 away from the port of suction valve, placing suction valve makes two of suction valve ports correspond to the output terminal of two test set respectively, second output terminal 221 drives point mouth to see the port of a close correspondence, supporting disk 233 preferentially touches the port of suction valve, and seal this port by inflation platform 235, second output terminal 221 extends further, and then with detecting head 132,212 penetrate in the port of suction valve; Corresponding first test set 1 also promotes the first output terminal 121 by the first driving member 12, thus carries out testing in the port driving the first venting part 11 and detecting head to penetrate suction valve.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
