Abstract

The invention relates to a pressure testing tool for an external pipeline of a gas storage bottle group in a station. A tee is sealed and fixed with a gas bottle; a front positioning plate and a back positioning plate are tightly arranged on the inner end surface of the tee; the front positioning plate and the back positioning plate clamp the tee and fix the tee through bolts and nuts; a sealing plug is tightly arranged at a water outlet in the outer end surface of the tee; an annular sealing ring and an end surface sealing ring are arranged between the water outlet in the outer end surface of the tee and the sealing plug; the outer end of the sealing plug tightly presses against a baffle plate; the front positioning plate and the back positioning plate of the baffle plate are fixed through bolts and nuts. The pressure testing tool is safe and reliable, convenient and quick, reusable and low in using cost.

Description

The outer pipeline structure for pressure test of air cylinder group for a kind of station
Technical field
The invention belongs to natural gas vehicle refueling station gas storage equipment technical field, particularly the outer pipeline structure for pressure test of a kind of air cylinder group.
Background technique
Air cylinder group is as a kind of natural gas filling station intermediate storage container, conventionally need to organize at bottle that air inlet and outlet end is set up operating end outside pipe system to be connected with the natural gas line on station.And operating end outside pipe system normally end adopt three-way interface form to be connected with exterior line, need to carry out corresponding pressure test according to standard regulation bottle group operating end outside pipe system, common test pressure is 27.5MPa.
Be to be welded on pipeline and to carry out pressure testing with plug in the past, after pressure testing completes, with burning torch, plug sliced off to rear polishing again, welding after the not reproducible use of plug and, welding and cutting bruting process waste time and energy, at the beginning of circuit design, also to leave cutting surplus.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides the outer pipeline structure for pressure test of a kind of station air cylinder group, it is safe and reliable, convenient and swift, can reuse, and user cost is low.
The present invention solves the technological scheme that its technical problem takes: threeway and gas cylinder sealing are fixing, the interior edge face of threeway tightens forward, rear position plate, forward and backward positioning plate is clamped threeway and is fixed by bolt, nut, on the exterior edge face water outlet of threeway near seal plug, between threeway exterior edge face water outlet and seal plug, there are hoop seal ring and end-face seal ring, the outer end of seal plug is near baffle plate, and the forward and backward positioning plate described in baffle plate is fixed by bolt, nut.
The present invention has following advantages: 1), adopt seal plug add hoop seal ring and end face seal coil structures, good sealing effect, can replace threeway external welding blind plate structure, convenient and swift; 2), save the workload of welder's welding tooling steel pipe and blind plate, time saving and energy saving; 3), owing to adopting stopper sealing structure, need not weld, do not destroy an original structure for the outer pipeline three-way joint element of bottle group; 4), utilize a bottle group pipeline air inlet/outlet threeway self structure to position, all stations are all applicable with air cylinder group turnover gas operating line.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is plan view of the present invention;
Fig. 2 is plan view of the present invention.
Embodiment
As shown in Figure 1, 2, threeway 4 is fixing with gas cylinder (not shown in FIG.) sealing, the inner (near gas cylinder end) face of threeway 4 tightens forward, rear position plate 9,2, forward and backward positioning plate 9,2 is clamped threeway 4 and is fixed by bolt, nut, on the exterior edge face water outlet of threeway 4 near seal plug 7, between threeway 4 exterior edge face water outlets and seal plug 7, there are hoop seal ring 5 and end-face seal ring 6, the outer end of seal plug 7 is near baffle plate 8, and the forward and backward positioning plate 9,2 described in baffle plate 8 is fixing by bolt, nut 3.
Fluted 10 on the end face of the close seal plug 7 of described baffle plate 8, the exterior edge face of seal plug 7 is embedded in described groove 10.Can prevent that seal plug 7 from moving relative to baffle plate 8, further increases and decreases sealing effect.
