Description
Technical field
This utility model belongs to Civil Air Defense Facilities field, in particular it relates to a kind of explosion wave proof check valve for gas-particulate filter.
Background technology
The explosion wave proof check valve door being installed in protection works feedwater piping; its Main Function is: when there is violent explosion outside; produce shock wave; during by pumping plant, pond, pipeline incoming valve; this valve can play " gear ripple ", the effect of " wave absorption ", it is thus possible to protection protection works internal staff's installation security effectively.It is a kind of for eliminating the impact of water hammer ripple caused in pipeline, the device that protective conduit and equipment are not damaged because of many reasons.Be applicable to all kinds of supply and drain water systems such as industrial and mineral, enterprise, skyscraper, power station, utilize the breathing of air in piston upper chamber room, make the shock wave of burst be buffered and alleviate dynamics, farthest avoid the device damage caused because of huge water hammer impulse force.Existing explosion-wave-preventing valve, owing to the supporting spring of its valve plate soaks in media as well throughout the year, easy corrosion, shorten the service life of explosion-wave-preventing valve.Additionally all there is no check function at existing explosion-wave-preventing valve, pipeline is typically both needed to by loaded check valve door, in case medium back flow.
To this, China presently, there are following patent:
Patent publication No.: CN202274113U, disclose a kind of explosion-wave-preventing valve, it includes valve body, and it is located at water-in flange and the water-output flange at this valve body two, in the middle part of described valve body, it is provided with safety device, is provided with connecting rod at this safety device by described water-in flange side, this connecting rod is cased with valve seat, and be located at the valve plate of this connecting rod front end, and it is provided with spring in this connecting rod.This utility model simple in construction, protective is strong, guarantees personal safety.But, this device does not possess check device, there is reflux problem, and only with a wave damping chamber, explosion-proof performance is the best.
Utility model content
For solving the problem of above-mentioned existence, the purpose of this utility model is to provide a kind of explosion wave proof check valve for gas-particulate filter.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of explosion wave proof check valve for gas-particulate filter, including valve body, valving, explosion-protection equipment, check device and discharge outlet；Described valve body is a hollow cylinder structure, and its left end is provided with water-in flange, right-hand member is provided with water-output flange；Valving is arranged in the middle part of valve body, and it includes valve plate, connecting rod, valve seat and elastic device；Described valve plate is arc surface near water-in flange side, and valve plate is connected with valve seat by connecting rod；Elastic device is arranged between valve plate and valve seat；Described elastic device includes crossed strip and the sealing shroud being sheathed on outside spring；Described explosion-protection equipment includes the first wave damping chamber and the second wave damping chamber；Described first wave damping chamber is arranged between valve seat and water-output flange；Described second wave damping chamber is arranged between valve plate and water-in flange；Described discharge outlet is arranged on valve body；Check device includes support and glueballs；Described support is arranged on the right side of water-output flange；Described glueballs is arranged in support；Described valve body is provided with relief valve at water-output flange.
Further, described connecting rod is sleeve-shaped connecting rod.
Separately, described valve seat and the integrated casting of valve body.
Separately have, the 2/3 of a length of first wave damping chamber of described second wave damping chamber.
And, described sealing shroud is rubber.
Again, it is provided with taper water inlet inside described water-in flange.
Further, described valve plate inner hollow.
The beneficial effects of the utility model are: use two-part wave damping chamber, first carry out when shock wave arrives disappearing to, when shock wave is strong, and the first wave damping chamber just can shed its potential energy, valve plate will not be touched, material proper flow in pipeline, if shock wave is relatively strong, after valve plate starts, second wave damping chamber can play a role, double insurance, prevents spring fatigue from causing fault, affects pipe safety.This design can increase the length of valve body, but being because wave damping chamber is hollow structure, so deadweight can't increase too many, but safer.First wave damping chamber's length is more than the second wave damping chamber, is stopped outside valve plate by shock wave, extends spring service life.The use of crossed strip can utilize the elastic force between spring and spring, structure is more stable, it is not easy to be out of order, shock wave has certain toleration, prosperity along with underground traffic, sometimes have shock wave during operation to produce, less shock wave wave damping chamber can be processed, it is not necessary to start explosion prevention function.The toleration of its shock wave depend on crossed strip coefficient, according to the position that valve uses, it can be carried out artificial control, and Vertical Spring is difficult to control to.Movable connecting rod, especially tubular movable connecting rod, has considerable flexibility, easily decline when receiving shock wave impact, the most easily reset, and save material, making valve weight reduction, when connecting rod is arranged along valve seat, effect is more preferable, does not haves valve plate and tilts to cause the difficult problem that resets.Valve seat and the integrated casting of valve body, structure is more stable, and is difficult to damage occur.Valve plate uses hollow design, saves material.Valve plate is set to circular arc type near water-in flange side, is conducive to guiding current, reduces impact, reduces the pressure of valving, increases the service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of explosion wave proof check valve for gas-particulate filter provided by the utility model.
Detailed description of the invention
Following example are used for illustrating this utility model, but can not be used for limiting scope of the present utility model.
With reference to Fig. 1, a kind of explosion wave proof check valve for gas-particulate filter provided by the utility model, including valve body 1, valving 2, explosion-protection equipment 3, check device 4 and discharge outlet 5；Described valve body 1 is a hollow cylinder structure, and its left end is provided with water-in flange 11, right-hand member is provided with water-output flange 12；Valving 2 is arranged in the middle part of valve body 1, and it includes valve plate 21, connecting rod 22, valve seat 23 and elastic device 24；Described valve plate 21 is arc surface near water-in flange 11 side, and valve plate 21 is connected with valve seat 23 by connecting rod 22；Elastic device 24 is arranged between valve plate 21 and valve seat 23；Described elastic device 24 includes crossed strip 241 and the sealing shroud 242 being sheathed on outside spring 241；Described explosion-protection equipment 3 includes the first wave damping chamber 31 and the second wave damping chamber 32；Described first wave damping chamber 31 is arranged between valve seat 23 and water-output flange 12；Described second wave damping chamber 32 is arranged between valve plate 21 and water-in flange 11；Described discharge outlet 5 is arranged on valve body 1；Check device 4 includes support 41 and glueballs 42；Described support 41 is arranged on the right side of water-output flange 12；Described glueballs 42 is arranged in support 41；Described valve body 1 is provided with relief valve 6 at water-output flange 12.
