Abstract
The utility model discloses a quick connector; a whole silicone rubber airbag is inlaid in the outer shell of a connector body, the upper end of the silicone rubber airbag is pressed by a connector body sealing cover and then is fixed on the outer shell of the connector body by a bolt, and the lower end of the silicone rubber airbag is pressed by a rubber water pipe connector, a rubber sealing pad and a spring pressing piece and then is fixed on the outer shell of the connector body by the bolt; an air inlet hose goes out from the rubber water pipe connector and then enters an air storage chamber formed by the outer shell of the connector body and the silicone rubber airbag; and a pipe retreating spring is fixedly welded on the spring pressing piece. The quick connector has the beneficial effects that: the airbag is convenient to fix, the sealing performance is good, the installation and the use are very convenient, the quick connector can be used right after being plugged in and automatically falls off after water is supplied, time is saved, and no safety hidden hazard exists.
Description
Technical field
The utility model relates to a kind of joint, particularly a kind of special joint that adapts with the passenger train water-feeding tank inlet pipe.
Background technique
The railway system generally all installs the equipment of water on the promising passenger train in big railway station, this equipment is called water bolt on the passenger vehicle.It mainly by valve well, main pipe draw water pipe, be used for the ON/OFF water supply line the special switch valve, be used to connect the special-purpose sebific duct (about 20 meters) of train water tank and be used to protect the bolt well cover of sebific duct mouth health to form.Because safety, the water inlet on the intake pipe that requires passenger car and the station must not screwed connection, is necessary for plug.
There are the following problems for original upward water:
1, the interface connection is insecure: because the passenger vehicle fill hose joint is " taper joint ", artificial sebific duct grafting strength is limited, comes off voluntarily owing to the effect of hydraulic pressure in last water process easily, thereby does not reach the purpose of water and waste the water source;
2, reduce passenger vehicle and effectively go up the water time: go up water conservancy project back and forth the switch pipeline valve must reduce passenger vehicle and effectively go up the water time.Particularly behind the train speed raising, because the dwell time shortens, many times can lead on the passenger vehicle water tank not full water, influence passenger's normal water, the while has also increased last water person's labor intensity greatly;
3, there is potential safety hazard: because last water is pressed for time, many times all be to pull out sebific duct earlier then to close valve, cause excessive and random the overflowing in water source, at north of china in winter, freezing of causing owing to the water source is excessive promptly influences the safety that safety of railway traffic also influences passenger and railroader.
Water swivel is gone up in more existing improvement, and equally also there are the following problems:
1, the fixing imprecision of air bag.Because adopt whole silk to press, slide distortion easily and cause leaking in the air bag end in last water process, shortened the working life of joint, also needs special tool to install simultaneously;
2, the easy slippage of tracheae.Improve joint and be provided with the tracheae connecting head in the joint end, what caused promptly that the end tracheae connects is unreliable, also caused simultaneously the end effective cross the water cross section reduce to have increased water resistance, caused the prolongation of last water time;
3, no spring moves back pipe mechanism.After Shang Shui finishes, cause head reliably not come off effectively automatically, there is potential safety hazard;
4, no air bag positioning boss: in assembly process, there be inconvenience, the airtight insecure problem of installing in the positioning of air bag easy deformation.
Summary of the invention
The utility model provides a kind of rapid pipe joint, can solve problems of the prior art.
The technical solution adopted in the utility model is such: a kind of rapid pipe joint, one silicone rubber air bag integral body is embedded in the joint body enclosure, the upper end is fixed by bolts on the joint body shell after the pressing of joint body sealing cover, and the lower end is fixed by bolts on the joint body shell after by robber cement pipe joint, rubber gasket, spring pressuring plate pressing.Whole silicone rubber air bag convenient fixing, simple in structure, favorable sealing property.
Air induction hose passes from the robber cement pipe joint, enters the air storing cavity that joint body shell and silicone rubber air capsule form then.Gas enters air storing cavity in last water process, and silicone rubber air bag and passenger vehicle water intake frictionally are clamped mutually.Tracheae enters air storing cavity and meets the fluid mechanics requirement, and non-joint midway is reliability and durability and reduced resistance to flowing water.
Be fixedly welded with on the spring pressuring plate and move back the pipe spring.Interrupting, finish the back in last water process relies on the elastic force that moves back the pipe spring that this joint is come off fast.
As optimal way, described silicone rubber air bag up and down two ends is evenly distributed with eight bolts hole respectively, corresponding respectively eight bolts.
As optimal way, described air induction hose passes rubber gasket, spring pressuring plate, silicone rubber air bag after passing from the robber cement pipe joint, just enters air storing cavity then.
As optimal way, described moving back on the pipe spring free end is welded with circular pad.Increase the area of contact of moving back pipe spring and train intake pipe, prevent crooked phenomenon.
As optimal way, described silicone rubber air bag is provided with positioning boss in two ends up and down, and the joint body shell is provided with corresponding with it concave surface.The silicone rubber air bag is fixed back concave surface and boss compresses mutually with bolt, make air storing cavity can bear bigger air pressure, make this rapid pipe joint can bear bigger last water pressure.
As optimal way, described robber cement pipe joint outside thread is connected with joint bottom safety cover.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are:
1, air bag convenient fixing, favorable sealing property;
2, install, use all very convenient, plug and play comes off after last water finishes automatically, saves time, and does not have potential safety hazard.
Description of drawings
Fig. 1 is a sectional view of the present utility model.
Mark among the figure: 1 is the joint body sealing cover, and 2 is the silicone rubber air bag, and 3 is the joint body shell, and 4 is air storing cavity, and 5 is joint bottom safety cover, and 6 is the robber cement pipe joint, and 7 for moving back the pipe spring, and 8 is spring pressuring plate, and 9 is rubber gasket, and 10 is air induction hose.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
As shown in Figure 1, a kind of rapid pipe joint, one silicone rubber air bag, 2 integral body are embedded in joint body shell 3 inside, the upper end is fixed by bolts on the joint body shell 3 after 1 pressing of joint body sealing cover, and the lower end is fixed by bolts on the joint body shell 3 after by robber cement pipe joint 6, rubber gasket 9, spring pressuring plate 8 pressings.Whole silicone rubber air bag 2 convenient fixings, simple in structure, favorable sealing property.
