Quickly enter use state.And said structure, during the adjustment of barrier film pressure-reducing valve pressure, the booster action of spring 52 can
To accelerate adjustment process.The top surface both sides side of fin 12 can make barrier film 2 be flowed along apart from the different setting of the axial location of barrier film 2
Enter the hydraulic pressure before 41 do not depressurize of end to impact as having a supporting role power when direction of outflow end 42 offset, so that more science
The impulsive force that ground distribution barrier film 2 is subject to, protection spring 52 will not deviate barrier film axial location, or even damage due to the impact.Should
The top surface of fin 12 is the ring-type spherical structure of a substantially indent, and the both sides side of fin 12 is neighbouring by 12 liang of lateral fins 12 of fin
The guide curve surface structure of the top surface inclination of barrier film 2, the structure can be in the case where current first pass or hydraulic pressure change, by water
Pressure is oriented to the barrier film 2 with energy-absorbing bradyseism, reduces impact of the hydraulic pressure to water pipeline.The above-mentioned barrier film 2 of the respective outer side edges of fin 12
Structure, it can effectively lift the degree of regulation of barrier film pressure-reducing valve, strengthen the voltage regulation performance of barrier film pressure-reducing valve.This kind of frame mode knot
Structure is simple, the outflow end easy to assembly and can receiving bigger interval range for flowing into the hydraulic pressure of end 41, exporting bigger interval range
42 hydraulic pressure, or even above-mentioned medium channel can be completely closed, under case of emergency, it can be used as the valve of cut-off water channel.
Above-mentioned fin 12 is in the deformation side of spring 52 and sets up the setting for coordinating two layers of barrier film 2, and inner septum 22 is by bullet
The effect of spring 52 and hydraulic pressure in control chamber 5 deforms upon towards the position of fin 12, and pressure is transferred to barrier medium by inner septum 22
Outer barrier film 21 is arrived again, and during product use, outer barrier film 21 flows into the hydraulic pressure shadow before the side of end 41 is depressurized neighbouring
Under sound, outer barrier film 21 tilts towards the neighbouring side of end 41 that flows into, and inner septum 22 is blocked the setting of dielectric separates with outer barrier film 21
Can ensure between inner septum 22 and outer barrier film 21 exist buffering, outer barrier film 21 will not related inner septum 22 deform upon（Subtract
Gently spring 52 is pullled toward the direction of end 41 is flowed into）, and because barrier medium is limited by closed barrier cavity 23, outer barrier film
During 21 local compressions are transferred to inner septum 22, Medium Diffusion can be blocked, reduces shadow of the local compression to inner septum 22
Ring, make the stress of inner septum 22 more science.
Specific embodiment of the present utility model is above are only, but design concept of the present utility model is not limited thereto,
All changes for carrying out unsubstantiality to the utility model using this design, all should belong to the row for invading scope of protection of the utility model
For.
