The utility model is mainly composed of a pull rod, a cylinder cover, a cylinder body, a piston, a tapered connecting nut, a cap and a sealing ring. The piston is arranged on the middle part of the pull rod and installed in the chamber of the cylinder body. The upper part of the pull rod protrudes from a central hole of the cylinder cover. The lower part of the pull rod protrudes from a central hole on the bottom of the cylinder body. The tapered connecting nut and the cap are installed on the lower end of the pull rod. The lower part of the cylinder body is provided with an air inlet opening. The center of the pull rod is provided with a high pressure water inlet passage. The pressure tester has the advantages of convenient installation and operation, no damage to a gas cylinder, accurate test data, direct pressure test and weighing on a weighing bridge, less time and labour and low cost.
Description
The utility model relates to the test of the fluid sealability of pressure vessel, particularly is a kind of universal liquefied petroleum gas steel cylinder pressure tester.
Liquefied petroleum gas steel cylinder need regularly detect, and whether can continue safe handling to identify it, and the hydraulic testing is wherein most important test item.The water test unit that present domestic gas cylinder is used is that pressure tester is directly placed on the gas cylinder valve seat mostly, and exerts pressure downwards with piston or leading screw, and pressure testing device is pressed on the gas cylinder valve seat tightly.This pressure that gas cylinder is applied reaches 1000-1600Kg, easy damaged gas cylinder not only, and can influence the accuracy of the gas cylinder rate of residual of surveying.Present pressure testing device all can not directly pressure testing on weighbridge, needs repeatedly to move water-filled gas cylinder, and the pressure testing process operation is loaded down with trivial details, waste time and energy, and the pressure testing device cost is higher.
The purpose of this utility model provides a kind of advanced more liquefied petroleum steel cylinder pressure tester, gas cylinder is injury-free in the hydraulic testing, and it is accurate to measure the rate of residual data with weight method, can be directly be pressure testing on the weighbridge of 300KG at range, easy and simple to handle, time saving and energy saving and cost is very low.
Above-mentioned purpose is realized by following technical proposals:
This pressure tester is made up of parts such as pull bar, cylinder cap, cylinder body, piston, attaching nut, back of the body cap, O-ring seal and clearance set screw.Piston is positioned at the pull bar middle part and is contained in cylinder chamber.Cylinder cap is contained in the cylinder body upper end.Stretch out from the cylinder cap center pit on pull bar top, and stretch out from cylinder body bottom center hole the pull bar bottom.The attaching nut is contained in the pull bar bottom, and back of the body cap is contained in the pull bar lower end and compresses the attaching nut lower surface.O-ring seal is contained in cylinder cap center pit, outside piston, cylinder body bottom center hole and cylinder body bottom surface outside surface respectively.The clearance set screw is contained in respectively on the upper and lower end face of piston.There is the radial air inlet hole at place, cylinder body bottom surface.Axial venthole is arranged above the cylinder cap.There is into water under high pressure passage at the pull bar center.
Pull bar and piston in the above-mentioned pressure tester are made of one, or processing is assembled into one then respectively.
Pull bar upper end in the above-mentioned pressure tester has external thread and the three-way connection that advances water under high pressure to be matchedly connected, and the lower end has external thread and attaching nut and back of the body cap to be matchedly connected.
Attaching nut in the above-mentioned pressure tester is conical, and its endoporus is a straight thread, and its cylindrical is a tapered tread, the installation that matches of the circular cone internal thread of this circular cone external thread and gas cylinder valve seat.
Attaching nut in the above-mentioned pressure tester makes with the ZQSn6-6-3 material, and perhaps the tapered thread with discarded liquefied petroleum gas cylinder valve processes, and can not damage gas cylinder valve seat screw thread.
Liquefied petroleum gas steel cylinder pressure tester by technique scheme is made can be contained on the cylinder valve seat easily, and gas cylinder is carried out the hydraulic testing.Because sealing is reliable, need not gas cylinder is applied downward pressure, to the gentle cylinder valve seat not damaged of gas cylinder, with the rate of residual of gas cylinder after the weight method measurement hydraulic testing, data are more accurate.Can be directly be pressure testing and weighing on the weighbridge of 300KG at range, the gas cylinder that will fill water is not shifted from one place to another, easy and simple to handle, time saving and energy saving, work efficiency is much improved, be used for the pressure testing of YSP-15 type gas cylinder, a workman per hour can easily finish the work for inspection amount of 30-40 gas cylinder, and work efficiency improves 2-3 doubly.Also can be used for the pressure testing of other various model steel cylinders of YSP series.Every cost of this pressure tester has only 300 yuan, and uses the longevity very long.
Accompanying drawing is an one-piece construction synoptic diagram of the present utility model.
In conjunction with the accompanying drawings embodiment of the present utility model is described below:
In the accompanying drawing, the 1st, pull bar, the 2,6,8, the 9th, " O " RunddichtringO, the 3rd, cylinder cap, the 4th, cylinder body, the 7th, piston, the 10th, taper connection nut, the 11st, back of the body cap.A is an air admission hole, and B is a venthole, and C is a water under high pressure passage into.
Present embodiment is made of one piston 7 and pull bar 1, also can separate machined be assembled into one again.Each parts is by being assembled into this pressure tester shown in the figure.Its pressure testing operating process is: taper connection nut 10 is linked to each other with the gas cylinder valve seat installs earlier, and this pressure tester is placed on the gas cylinder valve seat.In cylinder, fill the into pressurized air of 0.3-0.5MPa from air admission hole A then.Because pull bar 1 and piston 7 are connected in one by taper connection nut 10 and gas cylinder valve seat, can not move up, so can only be that cylinder body 4 is compressed air push and moves down, cylinder body 4 bottom surfaces be pressed on the gas cylinder valve seat.Taper connection nut 10 is subjected to pulling force upwards at this moment, and attaching nut 10 produces elastic deformations, and attaching nut 10 combines closely with gas cylinder valve seat screw thread and makes positiver sealing between pressure tester and the gas cylinder.At this moment again water under high pressure is injected gas cylinder from the channel C in the pull bar 1, carry out pressure testing.
