Utility model content
The purpose of this utility model is to make up the deficiencies in the prior art, provides a kind of for supply channel, the pressure controller solving stress problems in water system, to ensure normal water supply.
In order to reach the purpose of this utility model, technical scheme is as follows:
A kind of pressure controller, there is body, it is characterized in that, described body interior is provided with dividing plate and barrier film, pressure controller interior separation is become inhalant region, exhalant region and zone of transition with barrier film by described dividing plate, and described divider ends abuts with in the middle part of barrier film, is provided with hydraulic pressure control assembly in described zone of transition: when hydraulic pressure exceedes setting value, hydraulic pressure control assembly at hydraulic pressure move under influence, and makes to produce gap between dividing plate and barrier film; When hydraulic pressure is normal, hydraulic pressure control assembly acts on barrier film and barrier film and dividing plate is close to.
Preferably, described hydraulic pressure control assembly comprises the balancing frame abutted with described barrier film, spring that one end is connected with described balancing frame, the adjustable nut that is connected with the described spring other end.
Preferably, the two ends up and down of described barrier film are fixed in described body.
Preferably, described dividing plate horizontally set, described barrier film is vertically arranged, and inhalant region is positioned at the upside of described dividing plate, and exhalant region is positioned at the downside of described dividing plate, and zone of transition is positioned at the right side of described barrier film, and inhalant region and exhalant region are all positioned at the left side of described barrier film.
Preferably, described barrier film upper part region is arcuate structure.
The beneficial effect that the utility model has:
When hydraulic pressure in pipeline is lower than setting value, can realize automatically protecting tap water pipe network; After hydraulic pressure is normal, normal water supply state can be recovered again, complicated machinery and electronic installation just need not can realize Stress control, prevent line pressure be greater than set pressure and go wrong.Simple and practical, and pressure regulation spectrum is adjustable, practicality is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model pressure controller;
Fig. 2 is the structural representation of Fig. 1 septation.
Embodiment
Below in conjunction with embodiment, the utility model is further described, but protection domain of the present utility model is not only confined to embodiment.
Shown in composition graphs 1, a kind of pressure controller, has body 1, and when reality uses, body 1 is arranged on supply channel, prevents line pressure to be less than set pressure.Body 1 inside is provided with dividing plate 4, barrier film 6, upper cover 10 and lower cover 11, and body 1 interior separation is become inhalant region 2, exhalant region 3 and zone of transition 5 with lower cover 11 by dividing plate 4, barrier film 6 upper cover 10, inhalant region 2 correspondence have water inlet, exhalant region 3 correspondence have water delivering orifice.Dividing plate 4 end abuts with in the middle part of barrier film 6, and both abut instead of are fixedly connected with.Be provided with hydraulic pressure control assembly in zone of transition 5: when hydraulic pressure exceedes setting value, hydraulic pressure control assembly at hydraulic pressure move under influence, and makes to produce gap between dividing plate 4 and barrier film 6; When hydraulic pressure is lower than setting value, hydraulic pressure control assembly acts on barrier film 6 and barrier film 6 and dividing plate 4 is close to.Therefore, when normal condition, inhalant region 2, all to communicate with each other between exhalant region 3 and zone of transition 5, and when hydraulic pressure is lower than setting value, also only have inhalant region 2, not connected between exhalant region 3 and zone of transition 5.
Hydraulic pressure control assembly comprises the balancing frame 7 abutted with barrier film 6, spring 8 that one end is connected with described balancing frame 7, the adjustable nut 9 that is connected with described spring 8 other end.Upper cover 10 and lower cover 11 are fixed by Flange joint, and the two ends up and down of barrier film 6 are fixed between upper cover 10 and lower cover 11.Basic with plane contact between balancing frame 7 and barrier film 6, the pressure of flow action on barrier film 6 can substantially all be acted on balancing frame 7.Current enter from the water inlet of pressure controller inhalant region 2, flow through barrier film 6, when pressure exceedes set pressure, namely exceed the acting force of spring 8 pairs of balancing frames 7, back down barrier film 6 and balancing frame 7, and water flows out from the water delivering orifice of exhalant region 3; When pressure is lower than set pressure, under the effect of spring 8, barrier film 6 tightly abuts with dividing plate 4, and inhalant region 2 and exhalant region 3 do not communicate, and non-water flow flows out.And hydraulic pressure control assembly allowable stress size realizes by regulating adjustable nut 9, the range of adjustment of the present embodiment is 0-2.5MPa.
Continue shown in composition graphs 1 and Fig. 2, in the present embodiment, dividing plate 4 horizontally set, barrier film 6 is vertically arranged, and inhalant region 2 is positioned at the upside of dividing plate 4, and exhalant region 3 is positioned at the downside of dividing plate 4, zone of transition 5 is positioned at the right side of barrier film 6, and inhalant region 2 and exhalant region 3 are all positioned at the left side of barrier film 6.And barrier film 6 upper part region is arcuate structure, arcuate structure is equivalent to the entire length of having elongated barrier film 6, when flow action is in barrier film 6 and when making barrier film 6 bend, arcuate structure can allow bending amplitude larger, and then make the gap between barrier film 6 and dividing plate 4 larger, utilize current to pass through.
Last it is noted that above embodiment only in order to illustrate the utility model and and technical scheme described by unrestricted the utility model, therefore, although this instructions has been described in detail the utility model with reference to each above-mentioned embodiment, but, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, and all do not depart from technical scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in right of the present utility model.
