Description
Technical field
The present invention relates to machinery valve fields, and in particular to pressure reduction non-return multifunction valve.
Background technology
Relief portion is by adjusting, inlet pressure being reduced to the outlet pressure of a certain needs, and by the energy of medium itself
Amount, makes outlet pressure automatically keep stable valve.Existing relief portion reduces water by valve inner flow passage to the local resistance of flow
The range of pressure, hydraulic pressure drop completes closing motion by the film of connection flap or the inlet and outlet differential water pressures automatic adjustment of piston both sides,
Do not have the function of non-return.Maximum caliber can only achieve DN600 on existing relief portion stricti jurise, be more than the decompression of DN800
Portion's effect of easing stress is mostly unsatisfactory, does not reach requirement.
Invention content
(1) the technical issues of solving
Present invention aims to overcome that the shortcomings that above-mentioned prior art, provides pressure reduction non-return multifunction valve, ensure big mouth
Diameter depressurizes the decompression of department, does not make medium back flow.
(2) technical solution
Pressure reduction non-return multifunction valve, including relief portion, shell and non-return portion；The shell is hollow pipe；The shell
It is provided with flange on the outside of both ends；Left section in shell is arranged in the relief portion；Right section in shell is arranged in the non-return portion；It is described
The nominal diameter of non-return portion is not less than DN800；The nominal diameter of the relief portion is not less than DN600.
Preferably, the shell is integral type or segmented.
Preferably, the stage casing of the shell is for reducer or with diameter section.
Preferably, the non-return portion is buffer closing silencing check valve.
Preferably, the relief portion is electric steam pressure reducing valve, electric butterfly valve or electric lever type pressure reducing valve.
Preferably, the relief portion is with the non-return portion by interlocked control, and in decompression process, non-return portion is completed to close
Afterwards, relief portion can start；
(3) advantageous effect
The present invention provides pressure reduction non-return multifunction valves, and the function of check-valves and pressure reducing valve is combined into one, entirely through
Pipe decompression and non-return can be realized in interlocked control, once mounting；Big channel heavy caliber can prevent medium back flow and protect
Demonstrate,prove decompression when bore is more than DN800.
Description of the drawings
In order to illustrate the technical solution of the embodiments of the present invention more clearly, will be described below to embodiment required
Attached drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for ability
For the those of ordinary skill of domain, without creative efforts, it can also be obtained according to these attached drawings other attached
Figure.
Fig. 1 is the structure chart of one embodiment of the invention；
Fig. 2 is the structure chart of another embodiment of the present invention.
In attached drawing, parts list represented by the reference numerals are as follows：
1- relief portions, 2- shells, left section of 201-, the stage casings 202-, right section of 203-, 3- non-return portions.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained all other without creative efforts
Embodiment shall fall within the protection scope of the present invention.
Refering to fig. 1, shown in Fig. 2, pressure reduction non-return multifunction valve, including relief portion 1, shell 2 and non-return portion 3.Shell 2 is sky
Heart pipeline, 2 both ends of shell outside are provided with flange, facilitate connection Outer Tube.Left section 201 in shell 2 is arranged in relief portion 1, only
It goes back to portion 3 and right section 203 in shell 2 is set.Non-return portion 3 is buffer closing silencing check valve, can be reduced using noise.Relief portion 1 is electricity
Dynamic pressure reducing valve, such as electric steam pressure reducing valve, electric butterfly valve or electric lever type pressure reducing valve, facilitate realization numerical control.Non-return portion 3
Nominal diameter is not less than DN800, and the nominal diameter of relief portion 1 is not less than DN600, to adapt to heavy caliber Outer Tube, ensures to open
When entirety flow.
In the use of the present invention, Outer Tube water inlet end connects relief portion 1, Outer Tube water outlet connects non-return portion 3.Non-return portion
3 prevent liquid reflux interference relief portion 1.Relief portion 1 is being subtracted by interlocked control using delay logical timer with non-return portion 3
During pressure, non-return portion 3 is completed after closing, and relief portion 1 can start.
In one embodiment, referring to Fig. 1, relief portion 1 is identical with 3 nominal diameter of non-return portion, and shell 2 is using integral type
Three sections of indentical tubes for being bolted or welding can also be used in indentical tube.
In another embodiment, referring to Fig. 2, relief portion 1 is different with 3 nominal diameter of non-return portion, the stage casing 202 of shell 2
For reducer, suitable reducer pipe or connector are selected as needed, are connected by screw bolts or are welded for two sections with left and right.
