Abstract
A kind of two wave damping chamber explosion-wave-preventing valve, it comprises valve body, valve seat, valve plate, spring, connecting rod, wave damping chamber, weep hole, described valve body is connected with valve seat, valve body two ends are respectively water-in flange and water-output flange, described weep hole is positioned on valve body, is provided with spring between described valve plate and valve seat, and described wave damping chamber is the first wave damping chamber and the second wave damping chamber, first wave damping chamber is between valve seat and water-output flange, and the second wave damping chamber is between valve plate and water-in flange.The utility model is bright to be had constructional simplicity and can stablize, and secondary treatment shock wave, has good wave dissipation effect.
Description
Technical field
The utility model relates to a kind of Civil Air Defense Facilities, particularly relates to a kind of two wave damping chamber explosion-wave-preventing valve.
Background technique
The single wave damping chamber that most prior art uses, is used for offsetting the shock wave that may occur.General is all use spring as elastic material control valve, spring under the environment such as water especially hot water get rusty easily, cause jerkyly being difficult to use once there is being difficult to the fault resetted, substance circulating in pipe can be caused not smooth, spring Reusability can cause elasticity to be deteriorated, and be easily out of shape, good explosion-wave-preventing effect cannot be played.Especially between water-in flange and water-output flange, pressure is excessive, affects the life-span.Its maintenance cost is high, needs to open valve body, and after valve seal is influenced, secondary uses and easily goes wrong.When shock wave is larger, single wave damping chamber is not enough to deal with, and still can affect pipe safety.A explosion-wave-preventing valve shock wave is not had to carry out secondary treatment at present.
Model utility content
Problem to be solved: for above problem, the utility model provides a kind of two wave damping chamber explosion-wave-preventing valve, and having constructional simplicity can stablize, and secondary treatment shock wave, has good wave dissipation effect.
Technological scheme: a kind of two wave damping chamber explosion-wave-preventing valve, it comprises valve body, valve seat, valve plate, spring, connecting rod, wave damping chamber, weep hole, described valve body is connected with valve seat, valve body two ends are respectively water-in flange and water-output flange, described weep hole is positioned on valve body, is provided with spring between described valve plate and valve seat, and described wave damping chamber is the first wave damping chamber and the second wave damping chamber, first wave damping chamber is between valve seat and water-output flange, and the second wave damping chamber is between valve plate and water-in flange.
Improve as further technological scheme of the present utility model, first described wave damping chamber's length is greater than the second wave damping chamber.
Improve as further technological scheme of the present utility model, described spring is crossed strip group, and described connecting rod is between valve seat and valve plate.
Improve as further technological scheme of the present utility model, described connecting rod is movable connecting rod.
Improve as further technological scheme of the present utility model, described movable connecting rod is sleeve-shaped movable connecting rod.
Improve as further technological scheme of the present utility model, described valve seat and the integrated casting of valve body.
Improve as further technological scheme of the present utility model, described valve seat hollow area is less than 2/3rds of valve plate area.
Improve as further technological scheme of the present utility model, described spring is ring-type arrangement.
Beneficial effect:
The utility model provides a kind of two wave damping chamber explosion-wave-preventing valve, and having constructional simplicity can stablize, and wave dissipation effect is good, can extend valve body working life, the better feature protecting personal safety as well as the property safety.
1 uses two-part wave damping chamber first, first carry out when shock wave arrives disappearing to, when shock wave is strong, the first wave damping chamber just can shed its potential energy, valve plate can not be touched, material proper flow in pipeline, if shock wave is comparatively 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 because wave damping chamber is hollow structure, so deadweight can't increase too many, but safer.
2 first wave damping chamber's length are greater than the second wave damping chamber, are stopped outside valve plate by shock wave, extend spring working life.
The use of 3 crossed strips can utilize the elastic force between spring and spring, structure is more stable, be not easy to be out of order, shock wave has certain tolerance, along with the prosperity of underground traffic, sometimes have shock wave during operation to produce, can process less shock wave wave damping chamber, do not need to start explosion prevention function.The tolerance of its shock wave depend on crossed strip coefficient, artificial control be carried out to it in the position that can use according to valve, and Vertical Spring is difficult to control.Even if crossed strip group one has gone bad the running that also can not affect other spring seats, more stable, working life is more of a specified duration.
4 movable connecting rods, especially tubular movable connecting rod, have good flexibility, easily decline when receiving shock wave and impacting, also easily reset, and save material, make valve weight reduction, the better effects if when connecting rod is arranged along valve seat, there will not be valve plate to tilt to cause the difficult problem that resets.
5 valve seats and the integrated casting of valve body, structure is more stable, and not easily occurs damaging.
6 valve seat hollow area are less than 2/3rds of valve plate area, for spring and connecting rod provide necessary support.
7 springs are ring-type arrangement, along valve seat arrangement, have better stability.
