Abstract
The utility model relates to a pressure testing device for internal-pressure sealing of gas cylinder thread, which is used for the connection of openings of seamless gas cylinders, liquefied petroleum gas cylinders and other gas cylinders. A pressure relief valve rod is arranged on the left end of a screw-threaded joint. One end of a high-speed hydraulic joint tube is arranged in the screw-threaded joint. A u-shaped elastic card is arranged on the high-speed hydraulic joint tube. The lower end of the screw-threaded joint is provided with an internal-pressure sealing of thread. The utility model with the advantages of simple structure, easy fabrication and use and reliable sealing performance can reduce workers' labour intensity and can enhance the production of pressuretight testing of the gas cylinders.
Description
The bottleneck that a kind of gas cylinder screw thread inner pressuring sealing pressure testing device is used for gas cylinders such as seamless gas cylinder and LP gas cylinder connects.
Before the utility model is made, in prior art, seamless gas cylinder and LP gas cylinder, its water test unit is connected with bottleneck, all adopts screw axis to pressed sealing device, causes gas cylinder elastic deformation to a certain degree, indivedual gas cylinders even generation plastic yield, directly influence data veracity and damage gas cylinder, and the workman to operate labour intensity big, production efficiency is low.
It is a kind of simple in structure, easy to install that the purpose of this utility model is to provide, and sealing property is reliable, and labour intensity is low, the gas cylinder screw thread inner pressuring sealing pressure testing device that production efficiency is high.
The utility model mainly is made up of release valve rod (1), screw thread inner pressuring sealing (2), threaded connector (3), U-shaped elasticity card (5), fast hydraulic pressure junction block (6).(6) one of fast hydraulic pressure junction blocks are contained in the threaded connector (3), on the fast hydraulic pressure junction block (6) U-shaped bullet shape card (5) are housed simultaneously, and screw thread inner pressuring sealing (2) is equipped with in threaded connector (3) lower end.
Description of drawings:
Fig. 1 is the utility model structural front view:
Threaded connector (3) left end is equipped with release valve rod (1), (6) one of fast hydraulic pressure junction blocks are contained in the threaded connector (3), U-shaped elasticity card (5) is housed on the fast hydraulic pressure junction block (6), fast hydraulic pressure junction block (6) is packed into and O-ring seals (4) is housed in the threaded connector (3) one, and screw thread inner pressuring sealing (2) is equipped with in threaded connector (3) lower end.During use this device is screwed in gas cylinder (7) the taper thread hole, threaded portion need not twine encapsulant.The other end of fast hydraulic pressure junction block (6) and test pump outlet connect, can carry out the hydraulic testing to gas cylinder, along with increasing of gas cylinder internal pressure, the sealing force of screw thread inner pressuring sealing and O-ring seals is also along with increase, sealing can make the gas cylinder withstand voltage test carry out smoothly also along with raising.
Compared with the prior art the utility model has the following advantages: 1, between simple in structure, easy to operate, this device and the gas cylinder thread without other encapsulant, its great advantage is progressively the increasing of gas cylinder internal pressure when utilizing hydraulic pressure test, automatically thread seal is lived, fast and reliable, and pressure is more high, and sealing property is more good; 2, the fast hydraulic pressure joint is connected between this device and the hydraulic test pump, operates both soon, and again easy, labour intensity is low, and sealing is reliable, and can improve gas cylinder withstand voltage test class output.
Claims (1)
1, the interior sealing pressure tester of a kind of gas cylinder screw thread is by release valve rod (1), threaded connector (3), O-ring seals (4), fast hydraulic pressure junction block (6) are formed, threaded connector (3) left end is equipped with release valve rod (1), (6) one of fast hydraulic pressure junction blocks are contained in the threaded connector (3), O-ring seals (4) is housed on the one head, it is characterized in that being equipped with on the fast hydraulic pressure junction block (6) U-shaped elasticity card (5), screw thread inner pressuring sealing (2) is equipped with in threaded connector (3) lower end.
