Description
Technical field
A kind of a kind of sealing performance test equipment of the utility model, and in particular to steel modeling crossover sub pneumatic sealing test work
Dress.
Background technique
Steel moulds crossover sub, and also known as PE steel moulds crossover sub, as steel pipe and modeling pipe (usually PE is managed, i.e. polyethylene pipe)
Between conversion connector, have been widely used for gas ductwork and water conservancy and transport two important industries.Itself includes lengths of steel pipes
With modeling pipeline section, by lengths of steel pipes and modeling pipeline section it is each it is open at one end it is opposite be clamped, and sealing ring is set in access section, outside is set
It sets metal clip and increases sealing effect, overall appearance is in three sections of end to end cylindrical bodies, and interlude outer diameter is (at docking outside section
Diameter) it is greater than the outer diameter in two sections of outside.But sometimes due to product defects or assembly crewman's misoperation, lengths of steel pipes and modeling pipe
For section it is possible that revealing at docking, the use if such product comes into the market has biggish security risk, therefore,
Before steel moulds crossover sub factory, need to test by stringent sealing performance.
In the prior art, artificial mode is usually used to block the both ends of steel modeling crossover sub, so that steel is moulded
In the state of sealing inside crossover sub, while steel modeling crossover sub both ends are clamped in force application apparatus such as cylinder or jack
Then sealing element is passed through compressed gas from the hole in the closeouts of one end therein, steel modeling crossover sub is then immersed in water
In case, its sealing performance is examined by observation bubble；There are following disadvantages for above-mentioned mode:
1. when operation, need that steel is manually moulded crossover sub and the force application apparatus such as cylinder or jack while being transported to water tank
In, it after test, then moves out, increases the burden of operator in this way, meanwhile, but also detection efficiency is lower, it is not able to satisfy life
The demand of production.
2. dynamics is more difficult to control in such a way that cylinder or jack pair steel modeling crossover sub both ends carry out squeezing sealing,
Dynamics is too small, is not easy to seal steel modeling crossover sub end；Dynamics is excessive, is easily damaged steel modeling crossover sub.
Utility model content
The purpose of this utility model is to provide a kind of steel to mould crossover sub pneumatic sealing test tooling, and the tooling is for detecting
Steel moulds the gas tightness of crossover sub, can not only effectively mitigate the burden of operator, improve detection efficiency, meanwhile, also
The sealing dynamics that steel modeling crossover sub both ends can be controlled guarantees its leakproofness and guarantees that the two of steel modeling crossover sub will not be damaged
End guarantees the quality of steel modeling crossover sub.
In order to solve the above technical problems, the technical scheme adopted by the utility model is:
A kind of steel modeling crossover sub pneumatic sealing test tooling, including workbench and rack, it is characterised in that: the workbench
Interior to be equipped with water tank, rack is installed on the workbench, and rack is equipped with movable plate and driving device I, and driving device I can drive shifting
Movable plate rises or decline, and the movable plate is equipped with driving device II, and the lower end of the movable plate is equipped with PE pipe fixing seat, institute
It states and is connected with steel pipe connection plug in driving device II, the steel pipe connection plug is equipped with gasket, and driving device II can

Sensor is connect with driving device II.
In this way, the described steel pipe connection plug be used to connect with the lengths of steel pipes of steel modeling crossover sub and by lengths of steel pipes into
Row sealing, the PE pipe fixing seat is used to connect with the modeling pipeline section of steel modeling crossover sub and be sealed modeling pipeline section, in this way, In
When operation, operator only needs the modeling pipeline section that steel is moulded to crossover sub to be placed in PE pipe fixing seat, then control driving dress
It sets II driving steel pipe and connects that plug is mobile towards the pipe fixing seat direction PE, so that the gasket connected under steel pipe connection plug is by steel pipe
Section is sealed, and then booster air pump makes full of compressed gas inside steel modeling crossover sub, and then control driving device I drives
Movable plate integrally moves down, so that steel modeling crossover sub integrally immerses in the water in water tank, is then sentenced by bubble
Whether the leakproofness for determining steel modeling crossover sub is qualified；After detection, control driving device I drives movable plate whole to moving up
It is dynamic, so that steel modeling crossover sub integrally leaves the water surface, then controls driving device II and steel pipe connection plug is driven to rise, so that steel
Gasket on pipe connection plug leaves lengths of steel pipes, then takes out steel modeling crossover sub；Operating process is simple, operative employee
People is more quick when detecting leakproofness, does not need to carry manually during use, it is only necessary to control driving device II, I
And the start and stop of air pump, significantly reduce the labor burden of operator；Meanwhile, it is capable to effectively improve detection efficiency.
Due to being equipped with pressure sensor in the valve rubber that is arranged in PE pipe fixing seat, the pressure sensor and driving are filled
II connection is set, when detecting, the parameter of pressure sensor is configured according to the product of detection, the parameter is changeable, most
The big bearing capacity for being no more than product, minimum should ensure that the leakproofness at its both ends, when driving device II drives steel pipe to connect plug
On gasket and lengths of steel pipes when contacting, it will downward power, such pressure sensor energy are integrally applied to steel modeling crossover sub
Enough according to the pressure Real-time Feedback detected to driving device II, driving device II is stopped according to the feedback of pressure sensor
Only, when the pressure that pressure sensor detects reaches its setting value, driving device II stops at once, realizes and connects to steel modeling conversion
