Abstract

The invention relates to a water jacket and air bag type sealing device for hydraulic test of an air bottle outside measuring method, in particular to a test container for forming seal between a waterjacket and a water jacket cover. The sealing device mainly comprises a pressure test joint, the water jacket cover, a pneumatic joint, a flange, a rubber air bag, a connecting flange and the water ja cket, wherein the pressure test joint is fixedly connected with the water jacket cover through a connecting bolt and an O-shaped ring which seals the connecting part; the pneumatic joint is fixedly connected to an outer circular face of the connecting flange; the rubber air bag and the connecting flange are placed between the flange and the water jacket and fixed through the connecting bolts; and the connecting faces of the connecting flange, the flange and the water jacket are sealed through an upper end face and a lower end face of the rubber air bag. The sealing device has a simple, compactand reasonable structure, has simple and convenient operation, is quick, effective and reliable to form a water jacket seal, can ensure smooth hydraulic test of the air bottle outside measuring metho d, and greatly improves the production efficiency.

Description

Gas cylinder outside measurement method hydraulic testing water jacket bellows seal device
Technical field
The present invention relates to a kind of gas cylinder outside measurement method hydraulic testing water jacket bellows seal device, specifically make the test chamber that forms sealing between water jacket and the water jacket plug.
Background technology
When gas cylinder being carried out the outside measurement method hydraulic testing (hereinafter to be referred as test), the seal form between water jacket plug and the water jacket all adopts the form of ring-like O-ring seal flat seal.The hermetically-sealed construction of this kind form when testing, needs water jacket plug is pressed on the water jacket, can reach sealing effectiveness, therefore, needs to increase water jacket plug hold-down mechanism, complex structure; Simultaneously, each test needs to carry out moisturizing in water jacket and comes exhaust, complicated operation; And the back is fragile because the planar rings RunddichtringO is squeezed, and causes seal failure and leaks, and therefore needs the frequent ring-like O-ring seal of changing, and can't test normally.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby provide a kind of easy and simple to handle, form the water jacket sealing fast, effectively, reliable, can guarantee that the hydraulic testing of gas cylinder outside measurement method carries out smoothly, the gas cylinder outside measurement method hydraulic testing water jacket bellows seal device that can greatly enhance productivity
According to technical scheme provided by the invention, gas cylinder outside measurement method hydraulic testing water jacket bellows seal device, comprise pressure testing joint, water jacket plug, pneumatic joint, flange, rubber pneumatic bag, joint flange, water jacket, described pressure testing joint is fixedlyed connected by coupling bolt, O type circle with water jacket plug, makes the connecting portion sealing by O type circle; Pneumatic joint is fixedly connected on the joint flange periphery; Place rubber pneumatic bag and joint flange between flange and the water jacket, fix, and the joint flange and the joint face of flange, water jacket are sealed by the upper/lower terminal face of rubber pneumatic bag by coupling bolt.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Easy and simple to handle, form the water jacket sealing fast, effectively, reliable, can guarantee that the hydraulic testing of gas cylinder outside measurement method carries out smoothly, greatly enhance productivity.
Description of drawings
Fig. 1 is constitutional diagram before the structural test of the present invention.
Fig. 2 constitutional diagram during for structural test of the present invention.
Embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
As Fig. 1~shown in Figure 2: comprising: coupling bolt 1, O type circle 2, pressure testing joint 3, water jacket plug 4, pneumatic joint 5, flange 6, coupling bolt 7, rubber pneumatic bag 8, joint flange 9 and water jacket 10.
Pressure testing joint 3 of the present invention is fixedlyed connected by coupling bolt 1, O type circle 2 with water jacket plug 4, makes the connecting portion sealing by O type circle 2; Pneumatic joint 5 is fixedly connected on joint flange 9 peripheries; Place rubber pneumatic bag 8 and joint flange 9 between flange 6 and the water jacket 10, fix, and the joint flange 9 and the joint face of flange 6, water jacket 10 are sealed by the upper/lower terminal face of rubber pneumatic bag 8 by coupling bolt 7.
During test,, water jacket plug 4 is connected with being subjected to trial jar by pressure testing joint 3; Pressure testing joint 3 and be subjected to the sealing between the trial jar to adopt inner pressure sealed type screwed joint.
The trial jar that is subjected to that connects water jacket plug 4 is put into water-filled water jacket 10.
When the test water jacket need seal, open pneumatic joint 5 and insert low-pressure compressed air, the stable low-pressure compressed air of charged pressure in rubber pneumatic bag 8, rubber pneumatic bag 8 is expanded form air bag between back and joint flange 9 inner headed faces, the air bag that forms after rubber pneumatic bag 8 expands and the periphery of water jacket plug 4 bottoms fit tightly, form sealing state, make water jacket become the test chamber of sealing.
After test is finished, open pneumatic joint 5, get rid of the low-pressure compressed air in the rubber pneumatic bag 8, rubber pneumatic bag 8 recovers the state before the inflation, depressurization;
The present invention is according to GB/T9251-1997 " gas cylinder by hydrostatic pressure test method ", with reference to ISO6406-2005Annex E " Volumetric expansion testing of gas cylinders " (appendix E " volumetric expansion test of gas cylinder ") and CGA C-1-1996 " hydraulic test method of pressure gas gas cylinder " design.
