Description
Technical field
The utility model is related to pressure testing device field, more particularly, to float shoe valve element pressure testing device.
Background technology
Float shoe is used to guide tubing string smoothly to enter well, buoyancy during adjustment setting of casing, and is accurately controlled in well cementation in sleeve pipe
The height of cement plug is so that it is guaranteed that cementing quality.The critical component of wherein float shoe is the non-return valve in the middle of float shoe, and it is in well cementation
When effect be to prevent mud from flowing backwards.Usual mud pressure is up to more than ten MPas during well cementation, if non-return valve goes wrong, greatly
The mud of amount can be leaked to water proof tube cavity to form cement plug, cause special proportioning mud to waste, and not only increase marine
Drilling platforms operating cost, while being affected to environment, so anti-internal pressure performance and the sealing of whole float shoe ball valve
The sealing of ball is the most important thing of whole float shoe quality control.Because float shoe structure is special, various performance detections get up to have not
Small difficulty.
The content of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and provides a kind of float shoe
Valve element pressure testing device.
The new technical scheme of the utility model is：Float shoe valve element pressure testing device, including non-return valve, pressing plate, fastening screw,
Seal sleeve, sealing ring and nut, described pressing plate are divided into top board, lower platen, wherein described lower platen is placed on level
On workbench, non-return valve is located between top board, lower platen, and seal sleeve is buckled in the upper port of non-return valve, and described is close
There is sealing ring in big envelope cylinder, seal sleeve top is top board, is fastened between top board, lower platen by fastening screw, and tightly
Gu there is nut on screw rod, seal sleeve is connected by high pressure line with pressuring pump.
Described fastening screw is four.
Described fastening screw passes through nut adjusting tightness.
The beneficial effects of the utility model are：Simple in construction, convenient maintenance is practical, occupies little space, examination
Pressure energy power is high, while providing one intuitively checks float shoe pressure testing security situation condition.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is profile of the present utility model.
Wherein：1 be top board, 2 be fastening screw, 3 be non-return valve, 4 be lower platen, 5 be high pressure line, 6 be nut,
7 it is seal sleeve, 8 is sealing ring.
