Abstract
The invention discloses a kind of modified model anti-return 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, it is gradually reduced the open area of loop configuration, 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, the spring assembly that an above-below direction is flexible is set between baffle plate and pipe fitting inner body wall, the length that this spring assembly does not stretches is more than the thickness being hinged to hinge upper tubular member inner body wall.Advantage: the present invention 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, be close in loop configuration, stops fluid reflux；Setting a spring assembly between baffle plate and inwall, when losing fluid impingement force, spring force, baffle plate self gravitation and backflow power act on baffle plate jointly, accelerate the quick-make of baffle plate.
Description
Technical field
The present invention relates to a kind of modified model anti-return 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 the phenomenon of backflow, and fluid impulse force is relatively big, even if overcoming
Can this phenomenon, make back-flow preventer use smoothly and quick-make have some problems during backflow, so such as
It is badly in need of overcoming these technological deficiencies in producing this life.
Summary of the invention
The technical problem to be solved is the defect overcoming prior art, it is provided that a kind of modified model anti-return high pressure
Pipe fitting, it is achieved while solving fluid reflux phenomenon, weakening impulsive force by the design of circular arc, the setting of spring can be accelerated
The quick-make of back-flow preventer.
For solving above-mentioned technical problem, the present invention provides a kind of modified model anti-return high-pressure pipe member, including pipe fitting body, its
Feature is, the input of described pipe fitting body sets a loop configuration, and described loop configuration just uses circular arc to the side of input
Shape designs, and is gradually reduced the open area of loop configuration, and described loop configuration sets a baffle plate, described baffle plate back to the side of input
Upper end is fixed in loop configuration by hinge, sets the spring dress that an above-below direction is flexible between baffle plate and pipe fitting inner body wall
Putting, the length that this spring assembly does not stretches is more than the thickness being hinged to hinge upper tubular member inner body wall, and fluid is flowing to direction
Apply impulsive force, it is possible to make baffle plate upwards turn over, and pressuring spring shrinks.
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, 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；Setting a spring assembly between baffle plate and inwall, when losing fluid impingement force, spring force, baffle plate are from heavy sensation of the body
Power and backflow power act on baffle plate jointly, accelerate the quick-make of baffle plate；Present configuration is simple, and operable automatically has very
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 spring assembly, and 5 is hinge.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.Following example are only used for clearly illustrating the present invention
Technical scheme, and can not limit the scope of the invention with this.
As illustrated in fig. 1 and 2, a kind of modified model anti-return high-pressure pipe member, including pipe fitting body 1, it is characterized in that, described pipe fitting
The input of body 1 sets a loop configuration 2, and described loop configuration 2 just uses circular-arc-shaped design to the side of input, gradually subtracts
The open area of little loop configuration, can be with the slowing down fluid impulsive force to cannelure, and described loop configuration 2 is back to the side of input
If a baffle plate 3, described baffle plate 3 upper end is fixed in loop configuration 2, between baffle plate 3 and pipe fitting body 1 inwall by hinge 5
If the spring assembly 4 that an above-below direction is flexible, the length that this spring assembly 4 does not stretches is more than hinge 5 to hinge 5 upper tubular member originally
The thickness of body 1 inwall, fluid is flowing to direction applying impulsive force, it is possible to make baffle plate 3 upwards turn over, and pressuring spring shrinks.
In the present embodiment, described baffle plate 3 uses corrosion resistant plate.
In the present embodiment, described baffle plate 3 uses circular baffle plate, and radius is more than loop configuration less than loop configuration exradius
Inner circle radius.
In the present embodiment, the inwall of described pipe fitting body 1 is provided with the layer of resistance to punching.
In the present embodiment, the outer wall of described pipe fitting body 1 is provided with layer protective layer.
In the present embodiment, the internal layer of described protective layer is antirust coat, and antirust coat sets one layer of anticorrosive coat again.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For Yuan, on the premise of without departing from the technology of the present invention principle, it is also possible to make some improvement and deformation, these improve and deformation
Also should be regarded as protection scope of the present invention.
