The invention has advantages of jointing pipes quickly, fastening and saving water.
Description
Technical field
The present invention relates to a kind of fluid pressure bag tightening fast-acting pipe couplings that is used for water management on the railway passenger train.
Background technique
China railways still generally adopts traditional working method to the operation that passenger train replenishes domestic water (being called for short " going up water " in the industry): go up before the water, last water person is connected to tapered water-filling nozzle on the car body with the rubber aqueduct of ground well, opens water on the water supply valve then; Last water finishes, and last water person closes water supply valve, manually pulls up aqueduct then.The defective that this " going up water " mode exists has: the one, be difficult to accomplish (" pipe-mouth ") fastening joining, and main cause is that the pattern of " tapered water-filling nozzle " is various, and ground aqueduct mouth of pipe size relative fixed, thereby connect trouble, be difficult to accomplish well connect; The 2nd, because of connecting trouble, the last water time is urgent again, causes water person's psychological burden heavy, and it is big to take over labor intensity; The 3rd, be difficult to realize automatic control " separation of pipe-mouth ", required thus auxiliary time is long, is difficult to realize giving passenger vehicle epipodium water; The 4th, because it is pressed for time, have little time to close the water source, the aqueduct of manually pulling up still discharges water within a certain period of time outward, causes water yield waste big.
Summary of the invention
Technical problem to be solved by this invention is: for overcoming the disadvantage of water operation traditionally, provide a kind of fluid pressure bag tightening fast-acting pipe couplings, this joint is easy to operate, can significantly improve water efficient, and effectively reduces water resource waste.
The technical solution adopted in the present invention is: in the cavity of housing, be provided with the aqueduct joint that is communicated with pressure bladder, pressure bladder is fixed in the cavity of housing, and the enclosed space between this pressure bladder and the inner walls is the hydrodynamic pressure storehouse; The hydrodynamic pressure storehouse is provided with the fluid access way, and it is located on the wall body of pressure bladder or housing.
The present invention compared with prior art has following major advantage:
1. take over quick, convenient, fastening.
2. alleviated the adapter operation labor intensity.
3. make the automatic control of realization " separation of pipe-pipe " become possibility.
4. go up water efficient and significantly improve, for reducing the water operating personnel condition that provides the foundation that goes up.
5. prolonged effectively going up the water time of train.
6. water saving.

Embodiment
The invention will be further described below in conjunction with embodiment and accompanying drawing.
Structure of the present invention is as depicted in figs. 1 and 2: in the cavity of housing 1, be provided with the aqueduct joint 6 that is communicated with pressure bladder 2, pressure bladder 2 is fixed in the cavity of housing 1, and the enclosed space between this pressure bladder and housing 1 inwall is hydrodynamic pressure storehouse 3; The hydrodynamic pressure storehouse is provided with fluid access way 4, and it is located on the wall body of pressure bladder or housing.
Above-mentioned aqueduct joint 6 is the parts (see figure 1)s that are connected as a single entity with housing 1.Perhaps, see Fig. 2: aqueduct joint 6 is individual components, and is T-shaped, and it is provided with the outside thread with last jack panel 7 couplings.
Above-mentioned pressure bladder 2, its upper and lower end parts is fixedlyed connected with the wall body of housing 1.Its Placement can adopt: fixedly connected with the wall body of housing 1 by bonding, mold pressing or mechanical connection manner.Specific as follows:
The upper and lower end of pressure bladder 2 can pass through bonding mode, promptly fixedlys connected (see figure 1) with the wall body of housing 1 by binding material 5.Binding material 5 can adopt strength adhesive, for example " LOCTITE770+LOCTITE 401 " Bonds (as follows).
Bonding mode can be passed through in the upper end of pressure bladder 2, promptly fixedlys connected (see figure 1) with the wall body of housing 1 by binding material 5; Perhaps, mechanical connection manner can be passed through in the upper end of pressure bladder 2, promptly is fastened on the top (see figure 2) of housing 1 by tightening nut 11 and seal joint 10.Bonding mode can be passed through in the lower end of pressure bladder 2, promptly fixedlys connected (see figure 1) with the wall body of housing 1 by binding material 5; Perhaps, (see figure 2) by mechanical connection manner, is promptly fixedlyed connected by link and last jack panel 7 by the T-shaped aqueduct joint that interlocks with it 6 in the lower end of pressure bladder 2 with housing 1 bottom.Link is a permanent joint 8, or strength adhesive.
See Fig. 2: the mechanical connection manner of the lower end of pressure bladder 2 and aqueduct joint 6 specifically: aqueduct joint 6 is inserted in pressure bladder 2 from top to bottom, its T shape termination 9 is buckled on the edge of bottom through-hole of pressure bladder 2, its body passes housing 1 through permanent joint 8, upwards tighten along the outside thread of body by last jack panel 7 then, the lower end of pressure bladder 2 is fixed on the permanent joint 8 that is arranged in housing 1 inner chamber.
Fluid of the present invention is water or gas.
Sketch working principle of the present invention below in conjunction with accompanying drawing:
During the water filling operation, last water person up overlaps joint of the present invention, and the pressure bladder 2 and the water-filling nozzle 13 of railway passenger train water injecting pipe joint 12 are achieved a butt joint.Control water or gas then and enter hydrodynamic pressure storehouse 3 from fluid access way 4, under the extruding of fluid, pressure bladder is tightly encircled water-filling nozzle 13 outer walls, thereby has guaranteed that aqueduct joint 6 water outlet ports closely link to each other with water-filling nozzle, after this can open water supply valve and give the train water filling.Water supply finishes, the fluid that last water person needs only hydrodynamic pressure storehouse 3 overflows from fluid access way 4, make pressure reduction in the hydrodynamic pressure storehouse, so fluid pressure bag tightening fast-acting pipe couplings of the present invention separates automatically from the water-filling nozzle 13 of railway passenger train water injecting pipe joint 12.
