Abstract

The utility model discloses a pipe fitting. The pipe fitting is characterized by comprising an inner pipe and an outer pipe, the inner pipe is arranged inside the outer pipe in a penetrating mode, the inner pipe is provided with an extending section used for being connected with a pipeline, a cavity is formed between the inner pipe and the outer pipe, the cavity is internally provided with a buffer device, the buffer device is an air bag filled with gas, the inner pipe wall of the inner pipe is provided with a plurality of limit boards which are staggered, and a zigzag communicated flow pass is formed between the limit boards and the inner pipe wall of the inner pipe. The pipe fitting can prevent frost cracking and prevent a valve from being damaged by flushing of high pressure water.

Description

Pipe fitting
Technical field
The utility model relates to a kind of pipe fitting.
Background technique
Pipe fitting is the part that pipe is connected into pipeline, if pipeline is full of suddenly water, and the pressure of water is larger; easily wash out valve; in the time that the water in pipe fitting does not flow, easily freeze winter, and the density of ice is less than water; therefore after water freezing, can expand; due to the polytrope of weather and unpredictable, people cannot carry out effective protective measure on time, cause pipe fitting bursting by freezing; in addition when ducted hydraulic pressure is excessive, if do not have speed limiting device valve can be washed out.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of pipe fitting, can frost-cracking-preventing, and can protect the valve being connected on pipe fitting.
For achieving the above object, the utility model provides following technological scheme: a kind of pipe fitting, comprise inner tube and outer tube, described inner tube wears within the outer tube, described inner tube is provided with the extension for connecting tube, between described inner tube and outer tube, be provided with cavity, in described cavity, be provided with damping device, damping device is a gassiness air bag, on the inner tubal wall of described inner tube, be provided with several flow-limiting plates, described flow-limiting plate is staggered, and between described flow-limiting plate and the inner tubal wall of inner tube, forms the runner that complications communicate.
By adopting technique scheme, after the water freezing in pipe fitting expands, by large interior tube stay; owing to having air bag between inner tube outer tube; inner tube distortion extruding gasbag, air bag can be given reaction force of inner tube, balances out in inner tube part stressed; reach the effect of frost-cracking-preventing; current limiting plate in interior conduit simultaneously, in the time that high-pressure water flow flows through inner tube, by stopping of flow-limiting plate; flow velocity and pressure can reduce, thereby reach the effect of protection valve.
The utility model is further set to: inner tube, outer tube in described air bag and pipe fitting touch.
By adopting technique scheme, in the time that small distortion occurs inner tube, air bag just can be given reaction force of inner tube immediately, increases protection effect.
The utility model is further set to: described flow-limiting plate area is the long-pending half of inner tube pipeline section.
By adopting technique scheme, play when valve is protected, can not have much impact to normal use.
The utility model is further set to: the inner tubal wall of described extension is provided with filter screen.
By adopting technique scheme, make pipe fitting there is filtration, prevent valve blockage.
Accompanying drawing explanation
Fig. 1 is the utility model pipe fitting embodiment's structural representation.
Reference character: 1, outer tube; 2, air bag; 3, inner tube; 32, filter screen; 33, extension.
Embodiment
With reference to Fig. 1, the utility model pipe fitting embodiment is described further.
A kind of pipe fitting, comprise inner tube 3 and outer tube 1, described inner tube 3 is located in outer tube 1, described inner tube 3 is provided with the extension 33 for connecting tube, between described inner tube 3 and outer tube 1, is provided with cavity, in described cavity, is provided with damping device, damping device is a gassiness air bag 2, on inner tube 3 walls of described inner tube 3, be provided with several flow-limiting plates, described flow-limiting plate is staggered, and between inner tube 3 walls of described flow-limiting plate and inner tube 3, forms the runner that complications communicate.
By adopting technique scheme, after the water freezing in pipe fitting expands, inner tube 3 is supportted greatly; owing to having air bag 2 between inner tube 3 outer tubes 1; inner tube 3 is out of shape extruding gasbag 2, and air bag 2 can be to 3 one reaction forces of inner tube, balances out in inner tube 3 part stressed; reach the effect of frost-cracking-preventing; current limiting plate in inner tube 3 roads simultaneously, in the time that high-pressure water flow flows through inner tube 3, by stopping of flow-limiting plate; flow velocity and pressure can reduce, thereby reach the effect of protection valve.
Described air bag 2 touches with inner tube 3, outer tube 1 in pipe fitting.
By adopting technique scheme, in the time that small distortion occurs inner tube 3, air bag 2 just can be given 3 one reaction forces of inner tube immediately, increases protection effect.
Described flow-limiting plate area is the long-pending half of inner tube 3 pipeline sections.
By adopting technique scheme, play when valve is protected, can not have much impact to normal use.
Inner tube 3 walls of described extension 33 are provided with filter screen 32.
By adopting technique scheme, make pipe fitting there is filtration, prevent valve blockage.
