Description
Technical field
The utility model relates to the Rupture of Membrane pressure testing arrangement of the pressure that a kind of rocket projectile bay rupture of membranes produced.
Background technology
The method of existing test Rupture of Membrane pressure has sensor method and copper post manometric method, and the test request of Rupture of Membrane pressure is an instantaneous value, and the pressure measurement of copper post can not reacted the actual value that diaphragm breaks.Do not having under the fixing pattern and standard method of test, setting up a cover Rupture of Membrane pressure testing arrangement according to the requirement of test.
Summary of the invention
The purpose of the utility model is a Rupture of Membrane pressure testing arrangement reasonable in design, and test required pressure and relation value of diaphragm thickness when diaphragm breaks provide foundation and detection method for rocket projectile designs and produces.
The technical scheme that realizes above-mentioned purpose is following:
The Rupture of Membrane pressure testing arrangement mainly comprises: holding wire, pressure sensor, Pressure generator, pressure generating chamber, film pressing device, sealing column, tested diaphragm, clamp nut, pressure produce cartridge bag, electric igniter; Have closed hole in the middle of the sealing column; Pressure generating chamber has a stepped hole; Pressure generating chamber upper surface is the diaphragm loading platform; Tested diaphragm and sealing column, clamp nut connect as one puts into pressure generating chamber, and diaphragm loading platform external diameter is identical with tested diaphragm external diameter, through die arrangement tested diaphragm and pressure generating chamber is sealedly attached on the diaphragm loading platform; Pressure sensor is through on the stepped hole that is threaded in pressure generating chamber, and pressure sensor is drawn through holding wire from stepped hole.Pressure generator, film pressing device are processed with steel, and the whole wall thickness of pressure generating chamber guarantees the security of Rupture of Membrane pressure testing arrangement greater than 5 millimeters.Sealing column, clamp nut are the polythene material that light weight has certain intensity, measure the accuracy of Rupture of Membrane pressure when having guaranteed rupture of membranes, and relic do not damage the Rupture of Membrane pressure testing arrangement.Signal tape screen layer, length guarantee tester's safety greater than 5 meters.Pressure generator, film pressing device are for being threaded, and the length that is threaded is between 15 millimeters and 20 millimeters.
This Rupture of Membrane pressure testing arrangement diaphragm loading platform is designed to polish step according to tested diaphragm shapes, agrees with fully with tested diaphragm, guarantees air seal.The edge is consistent with tested diaphragm pressure rupture of membranes groove in the diaphragm loading platform; Tightly the edge that is pressed in tested diaphragm rupture of membranes groove when bore connects under the endoporus of film pressing device; Make firm being pressed on the diaphragm loading platform of tested diaphragm; Get out of the way tested diaphragm pressure rupture of membranes groove, guaranteed the reliability and the accuracy of test.The bigger one-tenth horn mouth of bore shape under the last relative aperture of film pressing device guarantees the intensity of film pressing device, also help tested diaphragm when being broken relic fly out smoothly, and protection Rupture of Membrane pressure testing arrangement is not damaged.
Description of drawings
Fig. 1 is a Rupture of Membrane pressure testing arrangement duty profile;
The specific embodiment
With reference to shown in Figure 1: to produce cartridge bag 5 fixing for pressure to pack the electric igniter of electric igniter 6 into; Then the ignition lead of electric igniter 6 is penetrated the closed hole 10 of sealing column 7; In closed hole 10, pour into fluid sealant, wait for letting fluid sealant solidify sealing fully more than 10 hours.Connecting sealing column 7 to the ignition lead of the electric igniter 6 that connects pressure generation cartridge bag 5 stretches out from the hole of tested diaphragm 8 together; Be fixed together to be integrally formed with clamp nut 9 and put into pressure generating chamber 2; Tested diaphragm 8 agrees with diaphragm loading platform 11; Film pressing device 1 and Pressure generator 2 are through being threaded, and the length that is threaded compresses tested diaphragm 8 at 16 millimeters.The film pressing device 1 of the Rupture of Membrane pressure testing arrangement that installs the front up; After fixing, Pressure generator 2 lies on the flame proof premises face; Sensor 3 is through on the stepped hole 12 that is threaded in pressure generating chamber 13, and holding wire 4 one terminates on the sensor 3, and the other end is connected on the acquisition system.When surveying Rupture of Membrane pressure, power up for electric igniter 6 to ignite pressure to produce cartridge bag and produce pressure, pressure acts on pressure sensor 3 through the stepped hole 12 of excess pressure generating chamber 13, is sent to acquisition system through holding wire 4, the force value when measuring tested diaphragm 8 ruptures of membranes.In the test, the diaphragm loading platform 11 and the tested diaphragm 8 of pressure generating chamber 13 are coated stop-leak compound, and sealing column 7 is coated the stop-leak compound sealing with diaphragm 8 contact positions.This device gas tightness is good, and needed transient pressure value can accurately test out tested diaphragm 8 ruptures of membranes the time.
Needed transient pressure value in the time of can testing out tested diaphragm rupture of membranes according to such scheme.
