Abstract
The utility model relates to a PCCP pipe joint sealing test apparatus comprising a pressure pump (1), a pressure gage (2), a diversion pipe (3), a pressure nozzle (4), a plug port disc (5), a bellmouth disc (6), and a plugging bolt (7), the pressure gage (2) is arranged on the pressure pump (1), an end of the diversion pipe (3) is connected with a water outlet of the pressure pump (1), the other end of the diversion pipe is connected with the plug port disc (5) through the pressure nozzle (4), and the plugging bolt (7) can be screwed on a water outlet of the bellmouth disc (6). The PCCP pipe joint sealing test apparatus can faithfully reflect rubber ring compressing deformation condition and joint water enclosing capacity of the PCCP pipe joint in different installing gaps of an installing process, testing equipment is simple, manpower and time consumption are reduced, test accuracy is improved, so test results are more real and effective.
Description
Technical field
The present invention relates to a kind of test unit of water stop gel ring sealing property, particularly can simulate PCCP pipe joint water stop gel ring experiments of sealing performance.
Background technology
In PCCP pipe joint test model, how simulating PCCP pipe joint water stop gel ring working condition is a major issue.The steel that actual PCCP pipe joint is adopted holds, socket connector, and socket is to be with reeded special shaped steel, and rubber ring installs later rubber ring and is subjected to Bidirectional-squeezing to form sealing force according to being filled in the groove with the rubber groove Section Design, bears high hydraulic pressure.Usually in the test of PCCP pipe joint rubber sealing, adopt actual pipeline to dock test, by conversion cushion rubber diameter, obtain the required numerical value of test.Cause weak point to be: expend a large amount of manpowers and time, the precision of installation is subjected to artificial factor affecting, brings larger error to test findings.
Summary of the invention
The object of the invention is to design a kind of test model of the PCCP of simulation pipe joint, it not only can reflect the cooperation assemblage gap of prototype PCCP pipe joint and cushion rubber is out of shape and joint closes the water pressure triadic relation, and test method is simple.
The ultimate principle of PCCP pipe joint leak tightness test device is to comprise a bellmouth dish, a jack fields by making, change cushion rubber compression deformation by the assemblage gap of adjusting bellmouth dish and jack fields, can reflect truly in the actual PCCP pipe joint installation process that when different assemblage gap, cushion rubber compression deformation situation and joint close outlet capacity.
PCCP pipe joint leak tightness test device basic structure is by pressuring pump (1), tensimeter (2), mozzle (3), suppress mouth (4), jack fields (5), bellmouth dish (6), shutoff bolt (7) forms, tensimeter (2) is installed on the pressuring pump (1), mozzle (3) one ends link to each other with pressuring pump (1) water delivering orifice, the other end links to each other with jack fields (5) by suppressing mouth (4), shutoff bolt (7) can be tightened in the apopore place of bellmouth dish (6), jack fields (5) all equates the socket groove that goes out by actual socket shaped steel groove dimensioned is arranged in the jack fields (5) and suppress the water filling catch basin with bellmouth dish (6) area thickness.
The present invention can truly reflect in the actual PCCP pipe joint installation process when different assemblage gap, cushion rubber compression deformation situation and joint close outlet capacity, and testing equipment is simple, have reduced manpower and time consumption, improved test accuracy, made test findings more authentic and valid.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention.By pressuring pump (1), tensimeter (2), mozzle (3), suppress mouth (4), jack fields (5), bellmouth dish (6), shutoff bolt (7), pressure test machine base (8), water stop gel ring (9), pressure test machine worktable (10).
Embodiment
In process of the test, at first jack fields (5) is put on the pressure test machine base (8); Preprepared water stop gel ring (9) is coated with spreads color and put on jack fields (5) the socket groove, cover bellmouth dish (6) and will guarantee that relative sliding does not steadily occur for it; Adjust pressure test machine worktable (10), pressure test machine worktable (10) is contacted with bellmouth dish (6); To the interior water filling of jack fields (5) catch basin, treat that water flows out from the water channel in the bellmouth dish (6), with shutoff bolt (7) sealing by pressuring pump (1).
Go out gap between jack fields (5) and the bellmouth dish (6) with vernier caliper measurement, pressurize with pressuring pump (1), until leakage point occurs, record the numerical value of tensimeter (2), open shutoff bolt (7) and carry out pressure release, rise pressure test machine worktable (10), measure the coating that remains on the bellmouth dish (6) and determine the cushion rubber deflection.
Repeat above-mentioned bulge test process, when recording jack fields (5) with bellmouth dish (6) different gap value, the pressure that cushion rubber leaks and cushion rubber variable quantity.
Claims (3)
1.PCCP pipe joint leak tightness test device, it is characterized in that: by pressuring pump (1), tensimeter (2), mozzle (3), suppress mouth (4), jack fields (5), bellmouth dish (6), shutoff bolt (7) and form, tensimeter (2) is installed on the pressuring pump (1), mozzle (3) one ends link to each other with pressuring pump (1) water delivering orifice, the other end links to each other with jack fields (5) by suppressing mouth (4), and shutoff bolt (7) can be tightened in the apopore place of bellmouth dish (6).
