Abstract
The utility model provides a sealing device for a water pressure test of a gas cylinder in a water jacket method. The sealing device comprises a water jacket and a water jacket cover, wherein a pressure testing thread joint is fixed on the water jacket cover; an inflation rubber ring is arranged between the water jacket and the water jacket cover; a compression handle is fixed on the upper end of the water jacket; an air valve is mounted at the lower end of the compression handle; one end of the air valve is connected with the inflation rubber ring; the other end of the air valve is connected with an air pump. The sealing device is simple in structure and convenient to operate; the compression handle is arranged on the water jacket, so that overall sealing property can be improved; the compression handle and the air valve act uniformly so as to ensure smooth processing of water pressure test of the cylinder in the water jacket method; the working efficiency of inspection personnel is improved.
Description
Technical field
The utility model relates to a kind of gas cylinder hydrostatic test outside measurement packoff, is specifically related to the leakage test container forming between water jacket and water jacket plug.
Background technology
At present when carrying out gas cylinder by hydrostatic pressure test, mainly contain two kinds of test methods, a kind of is the internal test method hydraulic testing, and another kind is hydrostatic test outside measurement, because the ratio of precision of gas cylinder internal test method experimental test is lower, its test findings often can not truly reflect the quality of gas cylinder quality.Gas cylinder hydrostatic test outside measurement packoff is that water jacket and water jacket plug sealing are tested, existing sealing means adopts the sealing of solid rubber ring type or bellows seal, the sealing of solid rubber ring type need to increase water jacket plug hold-down mechanism, complicated structure, each test need to be carried out moisturizing and gas cylinder handling in water jacket, and complicated operation, easily damages after its solid cushion rubber is squeezed, cause seal failure, therefore need the frequent O-ring seal of changing; Bellows seal device directly adopts inflating rubber ring to compress water jacket plug and seals, and because sealing plane area is large, sealing effectiveness is bad and easily cause residual bubble to be difficult for discharging, and affects test findings.
Utility model content
The utility model has designed gas cylinder hydrostatic test outside measurement packoff in order to address the above problem, its object is: provide a kind of simple in structure, easy and simple to handle, form sealing fast, reliably, can guarantee the packoff that gas cylinder hydrostatic test outside measurement carries out smoothly.
The utility model technical solution:
A kind of gas cylinder hydrostatic test outside measurement packoff, comprise water jacket and water jacket plug, in described water jacket plug, be fixed with pressure testing threaded connector, between described water jacket and water jacket plug, be provided with inflating rubber ring, it is characterized in that: described water jacket upper end is fixed with compression handle, compress handle lower end air valve is installed, described air valve one end is connected with inflating rubber ring, and the other end is connected with air pump.
The hold-down head of described compression handle is provided with rubber blanket.
Described pressure testing threaded connector upper end is connected with high-pressure water pipe, and lower end is connected with gas cylinder.
Described water jacket top is welded with a circle protective cover.
The beneficial effects of the utility model:
The utility model is simple in structure, easy to operate, is provided with compression handle and can improves test overall tightness on water jacket, compresses the unified action of handle and air valve, guarantees carrying out smoothly of gas cylinder hydrostatic test outside measurement, has improved reviewer's work efficiency.
Accompanying drawing explanation
Fig. 1: the utility model structural representation.
Wherein: water jacket 1, water jacket plug 2, compression handle 3, air valve 4, pressure testing threaded connector 5, gas cylinder 6, inflating rubber ring 7, protective cover 8.
Embodiment
Below in conjunction with accompanying drawing, illustrate the utility model.
As shown in Figure 1, a kind of gas cylinder hydrostatic test outside measurement packoff, comprise water jacket 1 and water jacket plug 2, in described water jacket plug 2, be fixed with pressure testing threaded connector 5, pressure testing threaded connector 5 upper ends are connected with high-pressure water pipe, lower end is connected with gas cylinder 6, between described water jacket 1 and water jacket plug 2, be provided with inflating rubber ring 7, water jacket 1 upper end is fixed with and compresses handle 3, compress handle 3 lower ends air valve 4 is installed, the hold-down head that compresses handle 3 is also provided with rubber blanket, and air valve 4 one end are connected with inflating rubber ring 7, the other end is connected with air pump, and water jacket top is also welded with a circle protective cover 8.
Water jacket 1 upper end is fixed with and compresses handle 3, compress handle 3 lower ends air valve 4 is installed, when test water jacket 1 need to seal, water jacket plug 2 is linked on water jacket 1, pulls and compresses handle 3, when moving downward, opens hold-down head the air valve 4 that compresses handle lower end, air pump carries out low inflation to cushion rubber, and the cylindrical that overlaps 2 bottoms with water cover after inflating rubber ring 7 expands fits tightly, formation sealing state, compression handle 3 on water jacket 1, simultaneously by water jacket plug 2 upper-lower compactings, makes water jacket 1 form the test chamber of sealing; On water jacket top, be also welded with a circle protective cover 8, when carrying out the hydraulic testing, can guarantee staff's safety around; After having tested, loosening pressed handle simultaneously air valve is closed, and gets rid of low-pressure compressed air in inflating rubber ring, state before inflating rubber ring recovers to inflate, depressurization.
Method of operating:
First by the gas cylinder integral hoisting of filling water to water jacket, in water jacket, fill with water; Secondly pressure testing threaded connector lower end screwed in to bottle mouth of gas cylinder internal thread and tightens, realizing between pressure testing threaded connector and gas cylinder and sealing; Again pull compression handle, open air valve simultaneously, the whole realization of water jacket and water jacket plug seals, and now can carry out to water filling in gas cylinder the running program of the hydraulic testing; The last hydraulic testing is complete, send out compression handle, closes gas check valve, shifts out gas cylinder, and a working cycle finishes.
To sum up, the utility model accomplishes the end in view.
