Abstract
The invention provides a novel anti-blast valve. The novel anti-blast valve comprises a valve body, a valve seat, a valve plate, springs, a connecting rod, a wave absorbing chamber and a drain hole; the valve body is connected with the valve seat; a water inlet flange and a water outlet flange are arranged at the two ends of the valve body, respectively; the wave absorbing chamber is located between the valve seat and the water outlet flange; the drain hole is located in the valve body; the spring is arranged between the valve plate and the valve seat; the springs are gathered into a transverse spring group; the connecting rod is located between the valve seat and the valve plate. The novel anti-blast valve has the characteristics of simple structure, stable properties and low self-weight.
Description
Technical field
The present invention relates to a kind of Civil Air Defense Facilities, particularly relate to a kind of new type explosion proof ripple valve.
Background technique
Use single of most prior art or singly organize Vertical Spring, the shortcoming of this spring is that receptance is poor, and under the environment such as water especially hot water get rusty easily, cause jerkyly being difficult to use.Impact when it is subject to shock wave, rushing the pressure before valve plate increases suddenly, forms strong pressure reduction before and after valve plate.Under the effect in hyperbaric chamber, spring is compressed, and valve plate arrives closed position rapidly, and shock wave is blocked in outside valve plate, has dissolved the collapsing force of shock wave.Under normal circumstances, after shock wave, valve plate is still in enable possition, pipeline returns to normal working state, but single or single group Vertical Spring stretchability is poor, occurs the fault being difficult to reset sometimes, and substance circulating in pipe can be caused not smooth, 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.
Summary of the invention
Problem to be solved: for above problem, the invention provides a kind of new type explosion proof ripple valve, and having constructional simplicity can stablize, lighter valve of conducting oneself with dignity.
Technological scheme: a kind of new type explosion proof ripple 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 wave damping chamber is between valve seat and water-output flange, and described weep hole is positioned on valve body, is provided with spring between described valve plate and valve seat, 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 invention, described connecting rod is movable connecting rod.
Improve as further technological scheme of the present invention, described movable connecting rod is sleeve-shaped movable connecting rod.
Improve as further technological scheme of the present invention, described valve seat and the integrated casting of valve body.
Improve as further technological scheme of the present invention, described valve seat hollow area is less than 2/3rds of valve plate area.
Improve as further technological scheme of the present invention, described spring is ring-type arrangement.
Beneficial effect:
The invention provides a kind of new type explosion proof ripple valve, having constructional simplicity can stablize, lighter feature of conducting oneself with dignity.
The use of 1 crossed strip 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.
2 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.。
3 valve seats and the integrated casting of valve body, structure is more stable, and not easily occurs damaging.
4 valve seat hollow area are less than 2/3rds of valve plate area, for spring and connecting rod provide necessary support.
5 springs are ring-type arrangement, along valve seat arrangement, have better stability.
