Abstract
The utility model discloses anti-explosion piping. A drainage pipe is cylindrical, one end of the drainage pipe is a seal end, and a water inlet is formed in the other end. A water outlet is formed in the side of the drainage pipe, and at least one drainage port is formed in the side of the drainage pipe and is disposed in one side of the water outlet, which is opposite to the seal end. A pressure plate is arranged in the drainage pipe and disposed between the water outlet and the at least one drainage port, and the pressure plate is in seal fit with the interior of the drainage pipe and capable of moving in the drainage pipe. A spring is connected with one end surface of the pressure plate, which is opposite to the seal end; the other end of the spring, which is opposite to the pressure plate, is connected with the seal end of the drainage pipe. When the water flow impacts the pressure plate, the speed is retarded to certain extent, and the water flow flowing into the water outlet slows down; when the flow speed of the water flow is high enough, the water flow extrude the pressure plate to enable the spring to be compressed, the pressure plate is disposed at the drainage ports, and accordingly, part of the water flow flows out through the drainage ports, and pressure at the water outlet is reduced; the pressure plate returns to the previous position after water flows out.
Description
Technical field
The utility model relates to pipe fitting, and more particularly, it relates to a kind of explosion-proof pipe fitting.
Background technique
Have at present a lot of pipe fittings not have quick-fried anti-characteristic, in the time that water velocity is excessive, pipe fitting is formed to larger pressure, As time goes on, pipeline can be unable to bear the impact of current, thereby causes pipeline burst.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of explosion-proof pipe fitting.
For achieving the above object, the utility model provides following technological scheme: a kind of explosion-proof pipe fitting, comprise a drainage pipe, described drainage pipe is cylindrical, one end of described drainage pipe is sealed end, the other end of described drainage pipe is water intake, there is water outlet the side of described drainage pipe, described drainage pipe side has a drain opening at least, described drain opening is in a side of the relative sealed end of water outlet, described drainage pipe inside is provided with pressing plate, described pressing plate is between water outlet and drain opening, the inner formation of described pressing plate and drainage pipe is sealed and matched and can in drainage pipe, moves, on an end face of the described relative sealed end of pressing plate, connecting spring, the other end of the described relative pressing plate of spring is connected to the sealed end of drainage pipe.
By adopting technique scheme, water is come in from water intake, impact on pressing plate, the speed of current has obtained slowing down to a certain extent, the current that flow in water outlet have obtained slowing down to a certain degree, alleviate pressure to water outlet, in the time that the flow velocity of current is enough large, current extruding pressing plate, makes spring-compressed, pressing plate is positioned at drain opening place, part current can flow out by drain opening, thereby have further alleviated the pressure of water outlet, after current are complete, promotion by spring to pressing plate, the position before pressing plate returns to.
The utility model is further set to: on described pressing plate side, annular groove is housed, described annular groove is provided with O-ring seals, and inner formation of described O RunddichtringO and drainage pipe is sealed and matched.
By adopting technique scheme, by O-ring seals is set on pressing plate, make the better tightness of pressing plate and drainage pipe inside, prevent that O-ring seals from having water to flow to one end of the relative drainage pipe sealing of pressing plate when cooperation with pressing plate for sealing.
The utility model is further set to: described spring surface has been coated with one deck steel antirust solution.
By adopting technique scheme, prevent that spring from getting rusty, affect the elastic force of spring, extend the working life of spring.
The utility model is further set to: the distance between described water outlet and drain opening is greater than the thickness of pressing plate.
By adopting technique scheme, make pressing plate after motion one segment distance, just reach drain opening, effectively play the effect of buffering, make water velocity obtain slowing down preferably.

Embodiment
Referring to figs. 1 through Fig. 3, the explosion-proof pipe fitting embodiment of the utility model is described further.
A kind of explosion-proof pipe fitting, comprise a drainage pipe 1, described drainage pipe 1 is cylindrical, one end of described drainage pipe 1 is sealed end 8, the other end of described drainage pipe 1 is water intake 6, there is water outlet 2 side of described drainage pipe 1, described drainage pipe 1 side has a drain opening 4 at least, described drain opening 4 is in a side of water outlet 2 relative sealed ends 8, described drainage pipe 1 inside is provided with pressing plate 3, described pressing plate 3 is between water outlet 2 and drain opening 4, described pressing plate 3 is sealed and matched with the inner formation of drainage pipe 1 and can be in the interior movement of drainage pipe 1, on an end face of described pressing plate 3 relative sealed ends 8, connecting spring 5, the other end of described spring 5 relative pressing plates 3 is connected to the sealed end 8 of drainage pipe 1, water is come in from water intake 6, impact on pressing plate 3, promote push pedal in the interior motion of drainage pipe 1, the speed of current has obtained slowing down to a certain extent, the current that flow in water outlet 2 have obtained slowing down to a certain degree, alleviate pressure to water outlet 2, in the time that the flow velocity of current is enough large, current extruding pressing plate 3, promote one section of longer distance of push pedal slip, spring 5 is compressed, pressing plate 3 is positioned at drain opening 4 places, part current can flow out by drain opening 4, thereby further alleviate the pressure of water outlet 2, after current are complete, due to spring 5 compressed after can produce elastic force, thereby promote pressing plate 3, make pressing plate 3 return to previous position.
On described pressing plate 9 sides, annular groove 9 is housed, described annular groove 9 is provided with O-ring seals 7, described O-ring seals 7 is sealed and matched with inner formation of drainage pipe 1, by O-ring seals 7 is set on pressing plate 3, make pressing plate 3 and the better tightness of drainage pipe 1 inside prevent when O-ring seals 7 and pressing plate 3 are sealed and matched having water to flow to one end that the relative drainage pipe 1 of pressing plate 3 seals.
Described spring 5 surfaces have been coated with one deck steel antirust solution, prevent that spring 5 from getting rusty, and affect the elastic force of spring 5, extend the working life of spring 5.
Distance between described water outlet 2 and drain opening 4 is greater than the thickness of pressing plate 3, makes pressing plate 3 after motion one segment distance, just reach drain opening 6, has effectively played the effect of buffering, makes water velocity obtain slowing down preferably.
