Specific embodiment

With reference to the accompanying drawings of the specification, the technical scheme in the utility model embodiment is clearly and completely described. Obviously, described embodiment is only the utility model a part of the embodiment, instead of all the embodiments.It is practical new based on this The embodiment of type, those of ordinary skill in the art's other embodiments obtained under the premise of not making the creative labor, It fall within the protection scope of the utility model.

The utility model is specially a kind of energy conservation applied in the industries such as municipal administration, water conservancy, sewage treatment, smelting, electric power Aobvious position valve, can be used in the distributing systems such as water delivery, water distribution, diving, chemical industry fluid and sewage pump plant, be able to achieve it is slow open, be truncated, valve Position display etc. is multi-functional, not only there are the other elements of protective conduit upstream and downstream to destroy from impact of water hammer, while also having non-return Effect.The aobvious position valve of energy conservation eliminates diaphragm seat (middle cover), by two cavity configurations on the basis of original multifunctional water pump control valve It is changed to single cavity structure；A micro- formula check-valves is increased in water inlet bypass pipe；Valve rod upper end is allowed to pass through at the top of valve deck, thus Function more than being able to achieve.

As shown in Figure 1 and Figure 2, the aobvious position valve of energy conservation includes valve body 7, flap 14, by the closed diaphragm 6 in 7 open end of valve body and valve Lid 1；Bypass line has conduit 10, block valve 8, filter 9, check-valves 15；Penetrate the valve rod 13 of valve deck 1, and and valve rod 13 are linked as whole flap 14, diaphragm pressing plate 5, diaphragm 6, nut 4 and nut 16；1 upper end through-hole of valve deck is equipped with O-ring 2 and valve Bar 13 is combined into sealing, prevents the fluid in valve from flowing outwardly；Valve deck 1, diaphragm 6 and valve body 7 pass through stud 11 and nut 12 It connects and fixed, valve body 7 is single flow, and inlet and outlet both ends communicate；Flap 14 is disc structure, and the body cavity of valve body 7 is arranged in It is interior, through fluid to the pressure of diaphragm 6, flap 14 can be driven to move up and down, thus connection or cut-out cock inlet and outlet；Valve rod 13 are limited in valve body 7 only moves reciprocatingly and linearly from top to bottom in the pilot hole of valve deck 1；Intake bypass line connect valve body 7 into Mouthful end to 1 through-hole of valve deck, between sequentially connected element have conduit, filter, block valve, check-valves 15, be discharged bypass line Connection valve body 7 exports to 1 through-hole of valve deck, between the element that connects have conduit 10, filter 9, block valve 8.

In out of service, the aobvious position valve of energy conservation is in close state pipe-line system in no Fluid pressure, opens water pump, Under the action of pump head, fluid begins to flow to the aobvious position valve of energy conservation, at this time sub-fraction fluid by 7 input end of valve body from into Water bypass line flows to the cavity (abbreviation diaphragm epicoele) that valve deck 1 and diaphragm 6 are formed, and flows to valve body using water outlet bypass line 7 outlets, while another part fluid flows to main valve body 7, pushes up valve opening valve 14, due to flap 14 and the also diaphragm 6 of valve rod 13 It is fixedly connected, flap 14 pushes up band dynamic diaphragm 6 and moves up, and since diaphragm epicoele is full of fluid, pushes up in diaphragm 6 Under the action of power, intracavitary fluid flows into 7 outlet end of valve body by water outlet bypass line from 1 through-hole of valve deck on diaphragm, to valve When standard-sized sheet, diaphragm epicoele fluid, which substantially discharges, to be finished, which is slowly to carry out, valve when completing starting water pump at this time Slowly open.Because reducing turn on pump water hammer most efficient method is to extend duration of valve opening, also because water pump detent torque is small, open Streaming current is big, and water pump zero delivery load is minimum, so the delayed start-up of exit of pump valve protects valve downstream pipe-line system In element, avoid open pump the destruction of bring direct hammer.

When valve opening, 13 upper end of valve rod is stretched out from 1 top through-hole of valve deck, and protrusion height can intuitively see that valve is It is no to have opened；When the valve is closed, 13 upper end of valve rod is just retracted into valve deck 1, can thus judge whether valve is complete Contract fully.

When pipe-line system is out of service or powers off termination of pumping suddenly due to contingency, exit of pump moment forms water column at this time It interrupts, due to the effect of gravity and 3 power of spring, diaphragm 6 drives flap 14 to move down, until closing.After the of short duration time, Fluid starts to flow back, and a part of fluid flows in main valve body 7, due to the closing of flap 14, blocks this segment fluid flow and flows to valve Door import, meanwhile, sub-fraction fluid flows to diaphragm epicoele by water outlet bypass line, since water inlet bypass line is equipped with only Valve is returned, the fluid of diaphragm epicoele, which cannot be continued through into water bypass line, flows to valve export, and this completes non-return function Energy.Water pump damages caused by solving the problems, such as because of termination of pumping bring water flow impulsion power, while solving because termination of pumping may make water pump The problem of high speed reverse rotation, motor is again started up rotor permanent deformation or burns out motor.

In normal operation, valve is in the open state for pipe-line system, if desired closes valve without the case where pumping of cutting off the water Under, the block valve 8 that need to only close on the utility model water outlet bypass line can be achieved with.Its working principle is that: it is other to close water outlet The block valve 8 on siphunculus road, at this moment the pressure in diaphragm epicoele and valve body 7 is effective area that is consistent, being formed due to 6 epicoele of diaphragm Greater than the area of flap 14, according to pressure law directly proportional to area, pressure, the pressure that diaphragm epicoele is formed is greater than fluid to valve The upward thrust of valve 14, flap 14 moves down at this time, realizes that the pressure of fluid is leaned in the quick closedown of valve, the closing of valve completely Power voluntarily controls；Similarly, when needing Open valve, the block valve 8 in water outlet bypass line, at this moment, diaphragm epicoele are opened Fluid is flowed out from water outlet bypass line, thrust of the insufficient pressure that epicoele is formed to overcome fluid upward to flap 14, at this time Valve is opened.
