Description
Technical field
It the utility model is related to check valve field, and in particular to a kind of encryption double containment environmental protection check-valves of manufacture.
Background technology
Social now, tap water almost flow into every household through pipeline and valve, as people are to water quality
It is required that raising, the requirement to the quality of running water pipe and valve is also correspondingly improved, but existing running water pipe and valve are sudden and violent
The problem of exposing is also more and more, and wherein the dispute in the management of tap water is difficult processing, wherein there is Railway Project to allow management
Person's particularly headache：Valve is juggled things on water meter before user's closing table achievees the purpose that water rate is not handed in few friendship even；User is because supply
Water pressure not enough causes useless water water meter to rotate generation expense and refuses to hand over water rate with ductwork pressure fluctuation.Valve before table is if common
Valve, then who either on or off, manager can just lose the control to pipe-line system at any time.
Number of patent application is a kind of encryption gate valve provided in 200820063446.9 utility model patent, it is necessary to specially
Tappet gear occlusion can be just set to reach so as to opening/shutting valve and only possess specific purpose tool with interior six sides password Magnetic tools
The purpose of manager's ability management and control pipe-line system, but the valve supporting must install anti-interference check-valves and just be avoided that because in pipeline
Some adverse consequences caused by fluid pressure fluctuations, make troubles to construction and management.
Existing check-valves is big to the resistance of current, causes flow dynamic to lose, and identical transportation range generally requires more
More power supports that energy consumption is big；In addition, the metal material such as existing check-valves generally use copper, iron is made, it is often residual in copper
A variety of harmful heavy metals such as remaining lead, mercury, and iron easily gets rusty, and often causes secondary pollution to tap water.
Simultaneously as the difference of area and height above sea level, causes the hydraulic pressure of every household different, and existing check-valves is to current
Resistance fix, it is impossible to each household, other different hydraulic pressure targetedly adjusts the resistance of check-valves, causes in actual use
Great inconvenience, in some instances it may even be possible to can cause damage to pipeline.
Utility model content
The utility model provides a kind of encryption double containment environmental protection check-valves, solves existing for check-valves in the prior art
The problem of different hydraulic pressure adjustment resistances cannot be directed to when poor anti-interference, energy consumption Datong District.
The technical solution adopted in the utility model is as follows：
One kind encryption double containment environmental protection check-valves, including main valve body, auxiliary valve body, the auxiliary valve body are arranged on going out for main valve body
Mouthful end, is equipped with connection ring between the main valve body and auxiliary valve body, convex along being radially provided with for connection ring on the inner ring of the connection ring
Platform, is equipped with first seal between the port of export and connector of main valve body, second seal is equipped between connector and auxiliary valve body,
The first seal and second seal structure identical include flap, pedestal, valve rod, one end connection flap of the valve rod
Bottom, the other end of valve rod is set in the sleeve on pedestal, and spring is arranged with valve rod, and bush outer sleeve is equipped with adjustment block,
Adjustment block is connected with bush whorl, and one end connection flap of the spring, other end connection adjustment block, the pedestal, which is equipped with, to be supplied
The through hole that current pass through, the flap top of first seal assembly is formed with the main valve body port of export to be sealed, second seal
Formed and sealed with boss at the top of flap.
In such scheme, the flap forms one end of sealing in coniform.
It is circumferentially arranged on the end face of the flap formation sealing to have multigroup o shapes seal washer in such scheme.
In such scheme, the material of the seal washer is silicon rubber.
In such scheme, the valve rod is uniform along in the circumferential direction of flap to be equipped with three groups.
In such scheme, the connection ring is internally formed the passage that even input end diameter is more than port of export diameter.
In such scheme, the main valve body, connector, the material of auxiliary valve body and flap are macromolecule engineering plastics.
In such scheme, the material of the spring is stainless steel.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are：
1. the utility model is pressed on shape on main valve body and connection ring by spring all the time by the setting of double seal, flap
It is sensitive reliable into end face seal, sealing closed mode can be kept under the fluctuation of a certain range pressure medium, is avoided trickle
Pressure change interference, solve the problems, such as that check valve of the prior art easily interference causes easy leak, at the same by adjusting
The setting of block, by adjusting the compression degree of spring, resistance of the adjustment check-valves to current so that this check-valves can be very good
Tackle each household hydraulic pressure different in other, using it is more convenient while protective effect is played to pipeline.
2. the utility model forms one end of sealing in coniform by flap so that medium can be divided well
Stream, reduces resistance, it is transversal to be more than inside nominal diameter for the flowing space cross-sectional area of formation after flap shift motion has been compressed
Face area, further reduces resistance.
3. by the setting of seal washer, better seal effect is reached, while guarantor is played to flap and valve body
Shield acts on.
4. seal washer uses silicone rubber material in the utility model, avoid and secondary pollution is carried out to medium.
5. valve rod, sleeve, spring and adjustment block are set to three groups in the utility model, whole seal ensure that
Stress balance, extends the service life and convenience of whole valve.
6. the utility model by the setting of connection ring internal channel, plays the role of pressurization, preferably avoid due to
Hydraulic pressure not enough causes the situation that flap rushes not open so that use is more convenient.
7. the utility model is by main valve body, connector, auxiliary valve body and flap by being arranged to macromolecule engineering plastics,
In the case of the stability that ensure that whole device, avoid and secondary pollution is produced to medium.
8. spring is arranged to stainless steel by the utility model, avoids and secondary pollution is produced to medium.
