Abstract
The invention discloses a hydraulic press sealing head mechanism with high universality and capable of quickly replacing a lower sealing body assembly. The pressure testing device has the advantages of strong universality, capability of testing pressure of workpieces with different pipe diameters, no damage to the workpieces, low cost and quick replacement.
Description
Technical field
The present invention relates to a kind of sealing head of high pressure pressure testing machine, relate in particular to a kind of hydraulic press sealing head mechanism of high universalizable fast changeable lower seal body assembly.
Background technique
Development along with mechanical industry, some tubular tools are (as the downhole tool of different size, the steel pipe of different size) under high-pressure situations, application is very extensive, and the Security of these instruments self directly has influence on on-the-spot production safety, so must carry out high-potting before application, and the high pressure pressure testing machine is all the instrument of the corresponding a kind of caliber of a sealing head at present, and a bench teat press can only meet the pressure testing workpiece of few several standard calibers, so not only cost is high, and the utilization ratio of equipment is low, versatility is not strong.In addition the pressure testing machine of highly versatile be all with the bracelet plug of two ends different size and workpiece screw on buckle after pressure testing, so not only can be to the damage that is buckled with of workpiece in the pressure testing process, and the pressure testing workpiece must obtain two ends screw buckle is arranged, button just cannot pressure testing.
The petroleum industry downhole tool pressure testing of take is example, because of downhole tool of a great variety, complex structure, the variation of different types of caliber is also very large.The downhole tool kind of producing as current river celebrating probing underground work company just has more than hundreds of, as, packet, rotating hanging device, catch ball device, sliding sleeve etc., wherein a kind of kind of the parts of float collar of crying just has tens kinds, diameter is distributed in 90mm between 400mm, if so the versatility of the downhole tool pressure testing pressure testing machine of multiple types specification is not strong, not only the input of pressure testing machine equipment can be very high, and the maintenance work of equipment is also quite heavy.Present much downhole tool manufacturing enterprises are in order to reduce the cost of pressure testing in addition, usually can adopt different pressure test tools to join different plugs (a kind of internal thread or externally threaded dome of carrying, before pressure testing, with outside thread or the internal thread of pressure testing workpiece, buckle), although cheap like this and simple, but can form damage to the screw mouth of instrument in the pressure testing process, instrument just is faced with the risk of wound button before not coming into operation, and downhole tool is convenient for pressure testing, just the two ends of instrument must be designed to the screw thread of bracelet at the beginning of design, no matter whether the downhole tool two ends need bracelet on function, will certainly shine into impact with using to the normal design of downhole tool like this.
In prior art, the Chinese patent that application number is 201020539016.7: the Chinese patent that the steel tube end part seal ring of steel pipe pressure test equipment and application number are 201020156402.8: the end part seal of high-pressure hydraulic system of steel tube pressure test equipment etc., these technology all exist that pressure testing caliber versatility is strong, a set of equipment can only be for the problem of the pressure testing of a certain caliber workpiece.
Summary of the invention
The purpose of this invention is to provide a kind of highly versatile, can for the workpiece pressure testing of different tube diameters, to workpiece without destroying, cost is low, hydraulic press sealing head mechanism that can quick-replaceable high universalizable fast changeable lower seal body assembly.
The objective of the invention is to be achieved through the following technical solutions:
The hydraulic press sealing head mechanism of high universalizable fast changeable lower seal body assembly of the present invention, comprise safety cover, sealing head top, lower seal body, seal ring, and described lower seal body and seal ring are the entire combination part, and described entire combination part comprises plurality of specifications.
As seen from the above technical solution provided by the invention, the hydraulic press sealing head mechanism of the high universalizable fast changeable lower seal body assembly that the embodiment of the present invention provides, because lower seal body and seal ring are the entire combination part, the entire combination part comprises plurality of specifications, highly versatile, can for the workpiece pressure testing of different tube diameters, to workpiece without destroying, cost is low, can change quick.
