Abstract
The invention discloses a kind of Novel backflow-preventing high-pressure pipe member, including pipe fitting body, it is characterized in that, the input of described pipe fitting body sets a loop configuration, described loop configuration just uses circular-arc-shaped design to the side of input, is gradually reduced the open area of loop configuration, and described loop configuration sets a baffle plate back to the side of input, described baffle plate upper end is fixed in loop configuration by hinge, and described baffle plate is provided with a sealing ring.Advantage: the present invention is it can be avoided that after fluid loses and flows to power, contingent backflow phenomenon, sets baffle plate by hinge, it is possible to make baffle plate fall after rise under effect according to gravity and reverse reflux power after losing impulsive force, it is close in loop configuration, stops fluid reflux；Baffle plate sets sealing ring, it is possible to be greatly improved sealing when stoping backflow；Loop configuration uses circular-arc-shaped design, is gradually reduced the open area of loop configuration, slow down the fluid impulsive force to loop configuration.
Description
Technical field
The present invention relates to a kind of Novel backflow-preventing high-pressure pipe member, belong to pipe fitting technical field.
Background technology
High-pressure pipe member has critically important purposes in the industry, and high-pressure pipe member changes, and fluid flows to, to connect pipeline etc. important
Effect, but can not be automatically prevented from fluid lose flow to power after backflow phenomenon, even if overcoming this phenomenon, sealing is not
Good, and fluid impingement force is relatively big, so being badly in need of overcoming these technological deficiencies in nowadays producing.
Summary of the invention
The technical problem to be solved is the defect overcoming prior art, it is provided that a kind of Novel backflow-preventing high-voltage tube
Part, while solving fluid reflux phenomenon, weakens impulsive force by the design of circular arc.
For solving above-mentioned technical problem, the present invention provides a kind of Novel backflow-preventing high-pressure pipe member, and including pipe fitting body, it is special
Levying and be, the input of described pipe fitting body sets a loop configuration, and described loop configuration just uses circular arc to the side of input
Design, is gradually reduced the open area of loop configuration, can be with the slowing down fluid impulsive force to cannelure, and described loop configuration is back to defeated
The side entering end sets a baffle plate, and described baffle plate upper end is fixed in loop configuration by hinge, and described baffle plate is provided with a sealing
Circle.
Further, described baffle plate uses corrosion resistant plate.
Further, described baffle plate uses circular baffle plate, and radius is more than in loop configuration less than loop configuration exradius
Radius of circle.
Further, described sealing ring uses O-ring seal, and its Ring Width size contacts with baffle plate and loop configuration
Face width degree is identical.
Further, the inwall of described pipe fitting body is provided with the layer of resistance to punching.
Further, the outer wall of described pipe fitting body is provided with layer protective layer.
Further, the internal layer of described protective layer is antirust coat, and antirust coat sets one layer of anticorrosive coat again.
The beneficial effect that the present invention is reached:
The present invention is it can be avoided that after fluid loses and flows to power, it may occur however that backflow phenomenon, set baffle plate, energy by hinge
Make baffle plate fall after rise under enough effects after losing impulsive force according to gravity and reverse reflux power, be close in loop configuration, stop
Fluid reflux；Baffle plate sets sealing ring, it is possible to be greatly improved sealing when stoping backflow；Loop configuration uses circular arc to set
Meter, is gradually reduced the open area of loop configuration, slow down the fluid impulsive force to loop configuration；Present configuration is simple, can be certainly
Dynamic operation, has good utilization prospect.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the cross section structure schematic diagram of the present invention.
In figure 1 is pipe fitting body, and 2 is loop configuration, and 3 is baffle plate, and 4 is sealing ring, and 5 is hinge.
Detailed description of the invention
