Abstract
The utility model discloses a novel anti -return high pressure pipe, including the pipe fitting body, characterized by, a loop configuration is established to the input of pipe fitting body, the loop configuration just adopts convex design to one side of input, and the actinal surface that reduces the loop configuration gradually is long -pending, a baffle is established back to one side of input to the loop configuration, the baffle upper end is fixed in the loop configuration through the hinge, be equipped with a sealing washer on the baffle. The advantage: the utility model discloses can avoid losing the flow direction behind the power at the fluid, the baffle is set for through the hinge to the backward flow phenomenon that probably takes place, can make the baffle fall after rise under the effect of impact force dorsal radix according to gravity and reverse flow power losing, hugs closely in the loop configuration, hinders the flow stopping body to flow back, the sealing washer is established on the baffle, the leakproofness when preventing the backward flow can be improved greatly, the loop configuration adopts convex design, and the actinal surface that reduces the loop configuration gradually is long -pending, has slowed down the impact force of fluid to the loop configuration.
Description
Technical field
The utility model is related to a kind of Novel backflow-preventing high-pressure pipe member, belongs to pipe fitting technical field.
Background technology
High-pressure pipe member has in the industry critically important purposes, and high-pressure pipe member has change fluid flow direction, connecting pipe etc. important
Effect, but the phenomenon flowed back after fluid loses and flows to power can not be automatically prevented from, even if overcoming this phenomenon, sealing is not
It is good, and fluid impingement force is larger, so being badly in need of overcoming these technological deficiencies in nowadays producing.
The content of the invention
Technical problem to be solved in the utility model is the defect for overcoming prior art, there is provided a kind of Novel backflow-preventing is high
Pressure pipe part, while fluid reflux phenomenon is solved, by the design of circular arc impulsive force is weakened.
To solve above-mentioned technical problem, the utility model provides a kind of Novel backflow-preventing high-pressure pipe member, including pipe fitting body,
It is characterized in that, the input of the pipe fitting body sets a loop configuration, and the loop configuration just adopts circle to the side of input
Cambered design, is gradually reduced the open area of loop configuration, impulsive force that can be with slowing down fluid to cannelure, the loop configuration back of the body
One baffle plate is set to the side of input, the baffle plate upper end is fixed in loop configuration by hinge, and the baffle plate is provided with one
Sealing ring.
Further, the baffle plate adopts corrosion resistant plate.
Further, the baffle plate adopts circular baffle plate, and radius is less than loop configuration exradius more than in loop configuration
Radius of circle.
Further, the sealing ring adopts O-ring seal, and its Ring Width size is contacted with baffle plate and loop configuration
Face width is identical.
Further, the inwall of the pipe fitting body is provided with the layer of resistance to punching.
Further, the outer wall of the pipe fitting body is provided with layer protective layer.
Further, the internal layer of the protective layer is antirust coat, sets one layer of anticorrosive coat on antirust coat again.
The beneficial effect that the utility model is reached：
The utility model can be avoided after fluid loses and flows to power, it may occur however that backflow phenomenon, set by hinge
Determine baffle plate, ring junction can be close to after impulsive force is lost according to baffle plate is fallen after rise in the presence of gravity and reverse reflux power
On structure, fluid reflux is prevented；Sealing ring is set on baffle plate, sealing when preventing backflow can be greatly improved；Loop configuration is adopted
With circular-arc-shaped design, the open area of loop configuration is gradually reduced, slow down impulsive force of the fluid to loop configuration；The utility model
Simple structure, operable automatically, having use well prospect.
Description of the drawings

Area, impulsive force that can be with slowing down fluid to cannelure, the loop configuration 2 sets a baffle plate 3 back to the side of input, described
The upper end of baffle plate 3 is fixed in loop configuration 2 by hinge 5, and the baffle plate 3 is provided with a sealing ring 4.
In the present embodiment, the baffle plate 3 adopts corrosion resistant plate.
In the present embodiment, the baffle plate 3 adopts circular baffle plate, radius to be more than loop configuration less than loop configuration exradius
Inner circle radius.
In the present embodiment, the sealing ring 4 adopts O-ring seal, and its Ring Width size connects with baffle plate and loop configuration
Contacting surface width is identical.
In the present embodiment, the inwall of the pipe fitting body 1 is provided with the layer of resistance to punching.
In the present embodiment, the outer wall of the pipe fitting body 1 is provided with layer protective layer.
In the present embodiment, the internal layer of the protective layer is antirust coat, sets one layer of anticorrosive coat on antirust coat again.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from the utility model know-why, some improvement and deformation can also be made, these change
Enter and deform also to should be regarded as protection domain of the present utility model.
