Background technique
With social progress, the development of urbanization has more and more gases, liquid to need to transport by pipeline, such as city
Water supply line, power station aqueduct, petroleum, natural gas line etc..
The pipeline transportation of long range usually needs to close main valve when there is operating condition variation.When main valve is closed, upstream and downstream
Pressure will generate big ups and downs, in order to which protective conduit and relevant device relief valve are given birth to because of fortune.However, conventional security relief valve is logical
It is often directly opened by spring or main safety valve, momentum valve and import and export signal piping etc. forms.Usually there is system complex, failure
Phenomena such as hidden danger is more, and property regulation is inconvenient, and decompression protection is slow.And traditional relief valve is frequently subjected to processing technology limitation etc. no
Sharp condition limitation, pressure relief capability are difficult to meet demand.
Summary of the invention
To solve the deficiencies in the prior art, the purpose of the present invention is to provide one kind to effectively reduce water suffered by transport pipeline
Hammer the double-direction relief valve of pressure into shape.
In order to achieve the above objectives, the present invention adopts the following technical scheme that:
Branch pipe(tube) with branch valve in parallel with main valve is arranged on main pipeline in a kind of double-direction relief valve.
Series connection decompression storehouse on above-mentioned branch pipe(tube), the intracavitary decompression equipped with wall in several vertical bin bodies of warehouse in the decompression storehouse
Valve block.
Further, the area of above-mentioned decompression valve block is identical as the sectional area of warehouse chamber.
Further, the spacing between above-mentioned decompression valve block is not mutually equal.
Further, the spacing between above-mentioned decompression valve block successively tapers off shape.
Further, above-mentioned decompression valve block is flexible material.
Further, the warehouse in above-mentioned decompression storehouse is a Duan Guanti of branch pipe(tube).
Further, above-mentioned decompression valve block is connected on the screw rod concentric with decompression storehouse.
Further, above-mentioned decompression storehouse is arranged in parallel with main pipeline, and both ends connect the branch pipe connecting with main pipeline by elbow
Road.
Further, above-mentioned decompression valve block is connected on the screw rod concentric with decompression storehouse, and the both ends of screw rod pass through
Screw hole appears elbow.
The invention has the beneficial effects that:
A kind of double-direction relief valve of the invention, by the way that the pressure release branch pipe(tube) in parallel with main pipeline is arranged, after playing closure main pipeline
Assist the effect of double-direction relief, concora crush；By decompression concatenated in branch pipe(tube) storehouse, the effect of buffering decompression is played；Pass through flexibility
Pressure release valve block, certain deformation is generated when being under pressure and impacting to support liquid drain；By adjusting pressure reducing valve piece quantity,
The operating pressure in adjustable decompression storehouse；By the different spacing between decompression valve block, pressure is mitigated with progressive mode differentiation.
A kind of double-direction relief valve of the invention, simple compared to existing pressure-relief valve structure, size is small, small using limiting,
Reliability is high, can effectively reduce, the two-way water hammer pressure in gentle transport pipeline, has very strong practicability and widely fits
The property used.

Specific embodiment
Specific introduce is made to the present invention below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of double-direction relief valve of the invention, in the series connection in parallel of the both ends of the main valve 1 of main pipeline
Branch valve 2, the branch pipe(tube) 6 for depressurizing storehouse 4.
The decompression storehouse 4 of this implementation is a Duan Guanlu of branch pipe(tube) 6, is arranged in parallel with main pipeline；The both ends in decompression storehouse 4 pass through
Elbow 3 is vertical with main pipeline to be connect, and branch valve 2 is serially connected on the vertical pipe.
Depressurize storehouse 4 warehouse it is intracavitary be equipped with concentric screw rod 5, the both ends of screw rod 5 are spirally connected the screw hole on elbow 3 respectively,
And elbow 3 is appeared, the screw hole is sealed after being spirally connected.
Several decompression valve blocks 7 are concatenated on screw rod 5, side end is vertically arranged with warehouse inner wall；The area of the decompression valve block 7 and storehouse
The sectional area of body cavity is identical, and the spacing setting successively to taper off；Material is preferably flexible material, such as rubber material.
Further, decompression valve block 7 can be fixed on casing 9 in advance, then casing 9 is socketed in outside screwed pipe, both ends are used
8 fixed sleeving 9 of nut, the step of to simplify installation, maintenance.
When installation,
Firstly, pressure release valve block and casing 9 first can be installed on Limit screw 5, then by mounted band pressure release valve block and casing 9
Screw rod 5 be installed to decompression storehouse 4 in, pressure release storehouse i.e. install；
Then, elbow 3 is installed by flange respectively in the both ends in pressure release storehouse, then screw rod 5 is fixed tightly on elbow 3 by nut 8,
And sealing is come with the nut of fastening 8；
The branch pipe(tube) 6 of branch valve 2 and side is installed on main pipeline by flange again；
Finally, elbow 3 is connect by flange with branch valve 2, then the elbow 3 of the other side is passed through into flange through branch pipe(tube) 6 and master
Pipeline connection；Complete the installation of double-direction relief valve.
In actual use,
When operating normally, liquid passes through the flow direction of main valve 1 right side from left side；
When main valve 1 is closed, branch valve 2 is opened；Upstream liquid pressure increases, when pressure is more than decompression 7 setting value of valve block, warp
Downstream discharge portion liquid, upstream liquid volume reduce in pressure release storehouse, and pressure buildup speed and increment reduce；When downstream water is hammered into shape
After baroreflex is returned, downstream liquid pressure increases, and at this time if downstream liquid pressure is greater than upstream pressure, liquid can pass through
Upstream pressure release of the pressure release storehouse to main valve.
After pressure is stablized, branch valve 2 can be closed to block upstream and downstream, reduce leakage probability.Liquid is needed in downstream
Supply, when needing to open main valve 1, first opens branch valve 2, is then turned on main valve 1 to play the pressure release effect in decompression storehouse 4.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
Understand, the above embodiments do not limit the invention in any form, all obtained by the way of equivalent substitution or equivalent transformation
Technical solution is fallen within the scope of protection of the present invention.
