Description

A kind of device suppressing instrument for the connection of multiple spot stagnation pressure tube
Technical field
The utility model relates to pressure device construction applications, particularly a kind ofly connects the device suppressing instrument for multiple spot stagnation pressure tube.
Background technology
When carrying out engine chamber test, need to adopt multiple spot stagnation pressure tube to measure firing chamber inlet and outlet pressure, need before the test to suppress leakage check to all pressure measurement pipelines of each stagnation pressure tube.Fig. 1 is a kind of multiple spot stagnation pressure tube and pressure measurement piping schematic.Multiple spot stagnation pressure tube is 7 measuring points, and in practice according to the difference of test, measuring point quantity is also different, and the most multipotency of stagnation pressure tube reaches more than 20 measuring point, even more.Each measuring point is positioned at the radome fairing 15 on pole 14, and each measuring point has an independent pressure measurement pipeline, realizes being connected by connecing mouth 8 and the pressure cap 17 in pressure measurement pipeline.Existing instrument of suppressing all only leaves a pipe adapter.The mode carrying out suppressing leakage check is at present connected suppressing the pipe adapter of instrument with the pressure cap 17 in pressure measurement pipeline, air hose 19 in pressure measurement pipeline is connected with pressure scanning valve 21, suppress and then check pressure measurement pipeline sealing by suppressing instrument, once can only suppress leakage check to single-point pressure measurement pipeline, suppress Shi Douxu at every turn and remove and install pressure cap.When adopting multiple spot stagnation pressure tube pressure measurement, especially adopting the stagnation pressure tube even more multi-measuring point of 20 multi-measuring points, suppressing leakage check by special labor intensive and time.In addition, existing leakage check method of suppressing can not carry out leakage check to pressure cap 17 in last interface both pressure measurement pipeline and stagnation pressure pipe nipple 8 connection of thread, and existingly suppress leakage check and also multiple spot stagnation pressure tube is not checked, can there is the insecure possibility of certain sealing, this will affect pressure measurements.
Utility model content
The purpose of this utility model is to provide a kind of device suppressing instrument for the connection of multiple spot stagnation pressure tube, the pole of multiple spot stagnation pressure tube to be inserted into from one end this contrive equipment and fit sealing, and instrument is suppressed in the connection of this device other end, by suppressing to suppressing instrument, so just once can suppress leakage check to all pressure measurement pipelines of a multiple spot stagnation pressure tube, once can check multiple pressure channel pipeline, the sealing of stagnation pressure tube and pressure measurement pipeline and stagnation pressure tube connection of thread can be checked again simultaneously, this will shorten test front setup time greatly, the accuracy of warranty test result.
The utility model provides a kind of device suppressing instrument for the connection of multiple spot stagnation pressure tube, it is characterized in that: described connects for multiple spot stagnation pressure tube the device suppressing instrument, comprises pipe adapter 1, closure plate 2, weldless steel tube 3, mount pad 4, pad 5, pressing plate 6, hexagon socket cap head screw 7;
Wherein: pipe adapter 1 is welded on closure plate 2, one of closure plate 2 and weldless steel tube 3 is welded to connect, and the other end of weldless steel tube 3 is connected with mount pad 4, mount pad 4 is processed with four internal threads; Pad 5 is pressed on mount pad 4, and stagnation pressure tube mount pad 12 is contained between pad 4 and pressing plate 6; Pressing plate 6 is divided into two parts in centerline one, is pressed on stagnation pressure tube mount pad 12, and with the fastening stagnation pressure tube mount pad 12 of hexagon socket cap head screw 7; Hexagon socket cap head screw 7 quantity is 4, matches with the internal thread of mount pad 4, plays final fit sealing effect.
When suppressing leakage check to multiple spot stagnation pressure tube, the pole 14 of multiple spot stagnation pressure tube is inserted into weldless steel tube 3 from mount pad 4, with pressing plate 6 press seal, and fastening with hexagon socket cap head screw 7.The mouth 8 that connects of multiple spot stagnation pressure tube is connected with pressure measurement pipeline pressure cap 17, the air hose 19 of pressure measurement pipeline is connected to the hose adapter 20 on pressure scanning valve 21, pipe adapter 1 is received and is suppressed instrument, by suppressing just once can suppress leakage check to all pressure measurement pipelines of multiple spot stagnation pressure tube to suppressing instrument.When carrying out suppressing inspection, when suppressing the stable reading of instrument at a fixation pressure, all pressure measurement pipeline good airproof performances of multiple spot stagnation pressure tube can be judged; When the unstable and continuous decrease of the reading suppressing instrument, namely pressure measurement pipeline exists and leaks, and checking each pipeline, finding leakage place and enhanced leaktightness by spraying leak detection gas-development agent.
Advantage of the present utility model:
The device suppressing instrument for the connection of multiple spot stagnation pressure tube described in the utility model, structure is simple, compact, easy to operate, use reliable, once can effectively realize suppressing leakage check to all pressure measurement pipelines of multiple spot stagnation pressure tube, pressure measurement pipeline sealing everywhere can be ensured simultaneously, greatly shorten test front setup time, warranty test result accuracy.
