Abstract
A pneumatic ring locking quick connector comprises a casing, wherein a gland is installed on the upper port of the casing, an air channel is arranged on the casing, the lower port of the casing is connected with a water conduit joint, and an air communicator is arranged in the water conduit joint. The pneumatic ring locking quick connector is characterized in that a wear protective sleeve is arranged in the casing, an air belt is rounded on the outer surface of the wear protective sleeve, and the air communicator is communicated with the air inlet of the air belt through the air channel. The pneumatic ring locking quick connector has the advantages of simple structure, convenient assembly, convenient operation, fast connection, firm connection, excellent wear resistance and long service life, is more convenient to operate when replacing components, can lighten the labor intensity of operators, improves the water feed efficiency, and prevents wasting water.
Description
Technical field
The utility model relates to a kind of air ring locking quick connector.
Background technique
When railway adds water for the passenger vehicle water tank, be to utilize the tubulose band of gas to be connected to tapered water nozzle on the train, open water supply valve then and go up water at bus stop; Last water finishes, and last water person closes water supply valve, again by manually pulling up aqueduct.The problem that traditional last water method exists is: 1, the tubulose band of gas and tapered water nozzle connect trouble, are difficult to accomplish to connect firmly; 2, connect and manage-the mouth separation process, last water person's labor intensity is big, and inefficiency is difficult to fill up water in the limited time.A kind of " rapid pipe joint of passenger train water inlet " is provided among the CN200948798, it is by housing, the aqueduct joint that is located at the pressure bladder in the housing and is communicated with it, pressure bladder is fixed in the cavity of housing, enclosed space between this pressure bladder and the inner walls is the hydrodynamic pressure storehouse, and the hydrodynamic pressure storehouse is provided with the fluid access way.During the water filling operation, last water person achieves a butt joint the pressure bladder and the train water injecting pipe joint of this joint, controls fluid then and enters the hydrodynamic pressure storehouse from the fluid access way, makes pressure bladder hug the water injecting pipe outer wall, opens water supply valve then and gives the train water filling.Water supply finishes, and the fluid that last water person needs only the hydrodynamic pressure storehouse overflows from the fluid access way, makes pressure reduction in the hydrodynamic pressure storehouse, and this rapid pipe joint just can break away from train water injecting pipe joint automatically.Because the water injecting pipe joint is an ironcasting, the surface has burr, and when the water injecting pipe joint was connected with this quick connector, the pressure bladder surface can produce cut; Split in the cut place when pressure bladder is subjected to the air pressure inflation, causes this quick connector to use.
CN201180880 has proposed a kind of " air ring is locked quick connector admittedly ", it has a cylinder body, in cylinder body, be provided with the pneumatic pressure of inverted cone and hold capsule, hold in pneumatic pressure and to be respectively equipped with corrugated rubber in the capsule from the bottom to top every capsule, annular piston and return spring, rubber is connected with annular piston every the capsule upper end, on cylinder body, be provided with gas channel, the gas channel import communicates with the cylinder body end opening, outlet communicates every capsule with rubber, be connected with aqueduct joint at the cylinder body end opening, be provided with the gas communication device in aqueduct joint, the outlet of gas communication device communicates with gas channel.Its practical value not quite, and complex structure are not easy to assembling.Particularly also exist the pneumatic capsule surface of holding to be scratched phenomenon by the water injecting pipe joint, when pneumatic when holding capsule and being subjected to the air pressure inflation cut place split, cause this quick connector to use.Therefore need often to change the pneumatic capsule of holding, but because the complicated decision of assembly structure complex operation when changing, labor strength is big, influences working efficiency.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that prior art exists, provide a kind of simple in structure, be convenient to the assembling, easy to operate, connect fast, connect fastening, wear-resisting property is good, long service life is convenient to change easily damaged parts, last water efficient height, anti-sealing waste can alleviate the air ring locking quick connector of going up water person's labor intensity.
The utility model is achieved in that
This air ring locking quick connector, comprise housing, in the housing upper end-hole gland is installed, on housing, be provided with gas channel, be connected with aqueduct joint in the housing lower end mouth, be provided with the gas communication device in aqueduct joint, its special way is: be provided with wear-resisting sheath in housing, be surrounded with the band of gas at wear-resisting jacket outer surface, the gas communication device communicates with band of gas suction port through gas channel.
Above-mentioned air ring locking quick connector has a steel wire ring near lower lip is embedding in wear-resisting sheath.
Above-mentioned air ring locking quick connector, the described band of gas is tubulose and is coiled in wear-resisting jacket outer surface.
Above-mentioned air ring locking quick connector, the described band of gas is an annular.
Above-mentioned air ring locking quick connector, wear-resisting sheath lower lip and inner walls are by being threaded.
Above-mentioned air ring locking quick connector, corresponding band of gas position is provided with exhaust port on housing.
The utility model has the advantages that: simple in structure, be convenient to assembling, easy to operate, connect fast, connect fastening, can prevent water resource waste.Because the wear-resisting property of wear-resisting sheath itself is good, and wear-resisting sheath is directly to contact by holding tightly with last head of the band of gas, thereby wear-resisting jacket surface is not easy to produce cut, even there is cut also to be not easy to produce the crack, so long service life.When needs are changed parts, because assembly structure is simple, operate easily, go up water person's labor intensity, water efficient in the raising thereby alleviate.
Description of drawings
Fig. 1 is the structural representation (corresponding embodiment 1) of this air ring locking quick connector;
Fig. 2 is this air ring locking quick connector and last head coupled condition schematic representation;
Fig. 3 is the structural representation (corresponding embodiment 2) of this air ring locking quick connector.
Among the figure: housing 1, exhaust port 101, steel wire ring 2, wear-resisting sheath 3, the band of gas 4, gland 5, gas channel 6, aqueduct joint 7, gas communication device 8, last head 9.
Embodiment
As shown in Figure 1, in housing 1 upper end-hole gland 5 is installed, on housing 1, be provided with gas channel 6, in housing 1, be provided with and the consistent wear-resisting sheath 3 of last head 9 shapes, in wear-resisting sheath 3 outer surfaces coiling the tubulose band of gas 4 is arranged, the band of gas 4 can adopt flexible rubber hose, near lower lip is embedding steel wire ring 2 is arranged in wear-resisting sheath 3, and wear-resisting sheath 3 lower lip and housing 1 inwall are by being threaded.Be connected with aqueduct joint 7 in housing 1 lower end mouth, be provided with gas communication device 8 in aqueduct joint 7, gas communication device 8 is drawn the back through gas channel 6 and is communicated with the band of gas 4 suction ports.The corresponding band of gas 4 positions are provided with exhaust port 101 on housing 1, put in place so that expand during the band of gas 4 inflation.
