With continued reference to Fig. 3, above-mentioned different hardness and thickness inner septum 22 and the structure setting of outer barrier film 21, for example
Barrier film pressure-reducing valve is used, when the water pressure fluctuations in pipe-line system for the first time, and harder outer barrier film 21 can preferably be born
Water impact, reduce deformation caused by the part of barrier film 2 is impacted.And softer thicker inner septum 22 is set, punching can be absorbed
Hit energy and play a part of bradyseism energy-absorbing, so that being capable of the balance of quickly restoring force inside barrier film pressure-reducing valve.Furthermore should
Kind inner septum 22 sets and barrier film 2 can be protected to be impacted from supporting pad 53 under water impact, and inner septum 22 fills with outer barrier film 21
It is different with position, after thickness hardness is also different, therefore both pads 53 supported are propped up, between inner septum 22 and the surrounding of outer barrier film 21
Certain space be present, deformation space is left after being hit to outer barrier film 21, this will also lift the durability and performance of product.
Be provided with a fin 12 with continued reference to Fig. 3, in above-mentioned medium channel, fin 12 is in crescent shape along the above-mentioned inwall of valve body 1
Circumferentially extending is set.Media flow direction in the vertical medium channel of the bearing of trend of above-mentioned fin 12 is set.Fin 12 is just
The external middle part of barrier film 21 is set, i.e., fin 12 is in the deformation side of spring 52 and set up.Fin 12 is in the deformation direction of spring 52
When upper setting can fill at the beginning of barrier film pressure-reducing valve, fin 12 coordinates barrier film 2 in the presence of spring 52, in medium channel
Flow of media there is certain barrier effect, during medium enters medium channel for the first time, influenceed by the structure, more
Ground enters feed line 31, so as to make barrier film pressure-reducing valve quickly enter use state.And said structure is in barrier film pressure-reducing valve
During pressure adjustment, the booster action of spring 52 can accelerate adjustment process.Above-mentioned fin 12 is adjacent to the above-mentioned side side of barrier film 2
Wall is equipped with the above-mentioned side that is bonded.The fin 12 is with being bonded the structure that side is equipped with adjacent to the side side wall of barrier film 2
Ring-type spherical structure of the fin 12 adjacent to the side side wall of barrier film 2 in a substantially indent, fin 12 with this adjacent to the side side wall of barrier film 2
The both sides side wall of connection is adjacent to the guide curve surface structure of the side sidewall slope of barrier film 2, the knot by 12 liang of lateral fins 12 of fin
Hydraulic pressure can be oriented to the barrier film 2 with energy-absorbing bradyseism, reduces water by structure in the case where current first pass or hydraulic pressure change
Press the impact to water pipeline.The above-mentioned structure of barrier film 2 of the respective outer side edges of fin 12, can effectively lift the regulation of barrier film pressure-reducing valve
Precision, the voltage regulation performance for strengthening barrier film pressure-reducing valve.This kind of frame mode be simple in construction, easy to assembly and can receive bigger section
Scope flows into the hydraulic pressure of end 41, the hydraulic pressure of outflow end 42 of the bigger interval range of output, or even can completely close above-mentioned medium and lead to
Road, 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.
