Description
Technical field
A kind of storage pressure test device is the utility model is related to, is that one kind is carried out using method on the outside of gas cylinder specifically
The pressure test device of test.
Background technology
Gas cylinder is a kind of common pressure vessel, and it not only needs to have good sealing, also has for its pressure-bearing property
High requirement.Gas cylinder pressure-bearing property can be quantified display by its deformation quantity, and the compression deformation quantity of gas cylinder, which need to control, to be referred to
Determine in scope, if deformation quantity is excessive, gas cylinder has the danger of explosion.Gas cylinder pressure-bearing property is measured typically to survey using outside measurement method hydraulic pressure
Try equipment to carry out, i.e., tested gas cylinder is put into the water jacket for filling water, then it pressurizeed, tested gas cylinder deformation is by one
Divide hydraulic pressure to enter in test tank, then remove pressure, a part of water is pushed back in water jacket, by measuring remaining water in test tank
Obtain the deformation quantity of gas cylinder.This detection mode simple, intuitive.Due to be pressurizeed to it, for the sealing requirements of sleeve
Very high, traditional sleeve seal part-structure is complicated, and because sleeve is commonly used, the hermetic unit of sleeve rubs repeatedly, its
Service life is very low to be changed, it is necessary to often safeguard, its use cost is high, is unfavorable for production energy-saving.
The content of the invention
The purpose of this utility model is to provide a kind of good airproof performance, storage pressure vdiverse in function, easy to maintain test
Device.
The utility model is realized by following technical scheme：A kind of storage pressure tests water jacket, including sleeve and upper shield, described
Sleeve is cylinder, and sleeve bottom closing, top, which is set, to be open, and the upper surface of opening extends inwardly to form spacing ring, spacing
Some necks are set on ring, and sleeve lateral wall bottom sets outlet pipe, and middle part sets water inlet pipe, and top sets connecting test pipe dress
Put；
Described upper shield side lower sets groove, and tetrafluoroethene pressure bladder is set in groove, and upper shield lower surface is set
Trip, trip are extended outwardly by upper shield following table, and the length of trip is slightly less than the depth of groove, are set in set hd top face center high
Water pipe is pressed into, high-pressure intake pipe passes perpendicularly through upper shield and extended downwardly, under high-pressure water inlet pipe end setting test splice, upper shield
Side sets gas-cylinder retaining assembly.
The sleeve is stainless steel sleeve, and upper shield is steel upper shield.
Compared with prior art, it is by the use of tetrafluoroethene air bag as seal means, in off working state for the utility model
Do not rubbed with barrel, its life-span is guaranteed, and pressure-bearing property of the utility model except that can test gas cylinder, and also gas cylinder can be entered
Row pressurization leakage detection, two detecting steps are completed using an instrument, improve detection efficiency, while save cost payout.

Embodiment
The utility model is described in further detail with reference to Figure of description：
A kind of test device of pressure vessel has been the utility model is related to, has been the air-tightness to tested gas cylinder specifically
And the water jacket that pressure-bearing property is tested.That includes a sleeve for accepting gas cylinder and the upper shield of a suspention gas cylinder, sleeve to be
Pressure-resistant rigid material is made, and preferably anti-rusting rate high metal or ceramic material, the utility model middle sleeve use stainless steel
It is made, its is cheap, will not get rusty.Water inlet pipe, outlet pipe and a testing tube are set in sleeve lateral wall, and testing tube connects
Test tank is connect, discharging valve is connected on water inlet pipe, atmospheric valve is connected on outlet pipe.
In the utility model, the bottom of described sleeve is hemispherical, and so designing is advantageous in that the equal stress of each several part
Uniformly, if be designed to it is flat, bottom margin be pressurized it is excessive, easily cause sleeve damage.The top surface of sleeve extends internally shape
Into a ring bodies, on ring bodies, some necks are provided with, the neck is uniformly arranged 3-4, and the ring bodies plays
One spacing effect is that ring bodies is a spacing ring, corresponding, and trip, the length of trip are set on the lower surface of upper shield
It is slightly less than the depth of neck, further, the diameter of upper shield is less than the annular diameters of ring bodies, and when closed, set is covered
Trip alignd with neck after upper shield is put into sleeve, then rotate upper shield and make trip neck stagger so as to which upper shield is stuck in into set
In cylinder, because the height of sleeve is highly identical substantially with tested gas cylinder, and provided enough in tested gas cylinder compression after sleeve
Big supporting force, therefore typically prevent upper shield from continuing the positioner to sink without setting again, if being intended to survey using same covering device
Different size of gas cylinder is tried, then also needs to set some positioning boss on the sleeve lining on the downside of spacing ring or directly set to determine
Position ring, positioning boss or the distance between locating ring and spacing ring are slightly larger than the height of trip.
In the utility model, both described sleeve and upper shield are when installation is with dismantling it is not tangible contact, only
Mutually it is close to due to the effect of air pressure in the course of the work, is so avoided due to the friction damage that installing/dismounting is brought repeatedly
Wound, greatly extend the service life of the test water jacket.
On described upper shield side, tetrafluoroethene air bag is set, the inflation inlet of tetrafluoroethene air bag is arranged on upper shield
On top surface, after upper shield is stuck in into sleeve, Paratetrafluoroethylene air bag is inflated, and makes air bag by the gap between upper shield and sleeve
It is completely filled with, the further sealing for improving test system, makes its test result more accurate.
Specifically, the upper shield side sets groove, and in particular, described groove is to be arranged in the middle part of upper shield
Annular groove, tetrafluoroethene air bag is bonded in annular groove, sets groove to give tetrafluoroethene air bag enough placing spaces, its
The air-tightness during device use can be ensured conscientiously.
In the top surface center of upper shield, a high-pressure intake pipe hunted leak to tested gas cylinder is set, and high-pressure intake pipe hangs down
Straight passes through upper shield and extends downwardly, and sets test splice in the end of high-pressure intake pipe elongated end, while cover setting in set
One air bottle connecting device, described air bottle connecting device are connected phase in height with gas cylinder in the downside of upper shield, test splice
It is mutually corresponding, it is ensured that after tested gas cylinder installs, test splice can be accurately disposed on the valve of gas cylinder.
Described in detail below with a specific example：
Sleeve is rinsed well with pure running water first, then closes atmospheric valve, discharging valve is opened and notes water to suitable
When height, do not overfilled to be suitable with being put into water after by trial jar.Then water will be filled in tested gas cylinder, then install tested gas cylinder in
On gas cylinder carriage below upper shield, test splice is torqued-up on tested gas cylinder, slings and is hung into water jacket by trial jar, set is covered tightly
Gu on water jacket.Aerating makes the tetrafluoroethene airbag aeration that set covers and seals water jacket.Open the valve on high-pressure intake pipe
To tested gas cylinder pressurization leakage detection.After the completion of leak detection, high-pressure intake pipe is closed, makes gas cylinder recover normal pressure, then to tested gas cylinder
Pressure-bearing leak detection is carried out by GB13077-2004 10.1.4 regulation, normal pressure will be replied in sleeve after the completion of experiment, to tetrafluoro second
Alkene air bag is deflated, and is opened upper shield and is hung out tested gas cylinder, and tested gas cylinder is covered into removal from set, changes next tested gas cylinder
Repeat the above steps.
