Abstract
The utility model relates to a station gas storage cylinder group outer pipeline pressure testing tool. A three-way joint is fixed with a gas cylinder in a sealed manner, the inner end face of the three-way joint is close to a front positioning plate and a rear positioning plate, the front positioning plate and the rear positioning plate clamp the three-way joint and fix the same through bolts and nuts, a water outlet of the outer end face of the three-way joint is close to a sealing end cap, an annular sealing ring and an end face sealing ring are arranged between the water outlet of the outer end face of the three-way joint, the outer end of the sealing end cap is close to a retaining plate, and the retaining plate is fixed with the front positioning plate and the rear positioning plate through bolts and nuts. The station gas storage cylinder group outer pipeline pressure testing tool is safe, reliable, convenient, quick, reusable and low in using cost.
Description
Technical field
The utility model 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 utility model provides a kind of station air cylinder group outer pipeline structure for pressure test, and it is safe and reliable, convenient and swift, can reuse, and user cost is low.
The technical scheme in the invention for solving the technical problem is: 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 utlity model 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.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the utility model plan view;
Fig. 2 is the utility model plan view.
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.
