The purpose of this utility model provides a kind of hydraulic principle that utilizes, and leans on hydraulic pressure to close automatically, again the valve that can manually often open.
The utility model is realized with following mode: a kind of semi-automatic, manual dual purpose water-saving valve, it is by valve seat, poppet shaft, handle, oil hydraulic cylinder, piston, press arm-tie, spring, block and central part have the screw of through hole to constitute, oil hydraulic cylinder and block are housed between valve seat and the handle, poppet shaft is passed the pressure arm-tie, spring is tightened with block and is connected handle, screw passes the corresponding aperture of pressing on two hole precessions of arm-tie piston and fixes, press arm-tie that two circular cone plush coppers are arranged, piston has an inlet opening and two hole for back flow, central part has the screw threads of through hole to fasten on piston, and the positioning boss of two symmetries is arranged on the block.Press two circular cone plush copper positions of arm-tie all corresponding with two hole for back flow of piston with size.
This is semi-automatic, the dual-use manual water-saving valve has compact structure, reasonable, easy to use, reliable, wear-resistant, long service life, the automatic shutdown seal performance is good, energy quantitative water supply and the automatic characteristics such as water or long-term water flowing of closing, in addition, also have manufactured materials and need not use copper material, price is lower, be easy to advantages such as installation.
Fig. 1 is semi-automatic, dual-use manual water-saving valve structural profile view (closed condition).
Fig. 2 is the A-A sectional view (auto state) of Fig. 1.
Fig. 3 is the B-B sectional view (full-gear) of Fig. 1.
Below in conjunction with accompanying drawing this dual purpose water-saving valve is described in further detail: oil hydraulic cylinder (2) precession valve seat (1) is fixing, central part has the screw (14) of through hole to pass packing ring (15), seal washer (16), packing ring (17) is tightened on piston (4), screw (6) passes presses arm-tie (5), spring (7), seal washer (12), O-ring seals (3) is tightened with block (8) and is connected handle (11), block (8) screws and covers in oil hydraulic cylinder (3) end, and two screws (6) pass two corresponding apertures of pressing on (5) two hole precession pistons of arm-tie (4) and fix.Press arm-tie (5) that two circular cone plush coppers are arranged.Piston (4) centre bit is equipped with an inlet opening (18) and two hole for back flow (19).Press two conical plush copper positions of arm-tie (5) all corresponding with two hole for back flow (19) of piston (4) with size.Cylindricality seal ring (13) is equipped with in hole for back flow (19) termination.When two conical plush copper correspondences were compressed into hole for back flow (19), by the sealing of cylindricality seal ring, pressed the same piston of arm-tie (5) (4) upper-end surface that 2 to 3 millimeters gaps are arranged this moment.The installation residue length of screw (6) should be able to make to move up in the clear in two circular cone plush coppers of pressing arm-tie (5) and all leave hole for back flow (19) and be advisable, that is screw (6) residue length can allow to press arm-tie (5) upper and lower mobile along screw (6) bar freedom.Oil hydraulic cylinder (2) side of piston (4) cooperates is equipped with O-ring seals.Block has the positioning boss of two symmetries on (8), is used for supporting the handle (11) that has lifted, and for handle (11) rotates conveniently, boss can be done the bevel rising.Handle is equipped with pointer on (11), and witness marker is used when being convenient to operator's operated valve.
Its automatic-closing valve process is such: the pointer of handle this moment (11) is in " automatically " position of valve gap (8).The operator is pulled outwardly handle (11) with hand, drive poppet shaft (10), press arm-tie (5) to move up, spring (7) is subjected to force compresses, make and press the arm-tie (5) and the gap of screw (6) to eliminate, press two roundlet coneheads and cylindricality seal ring (13) generation space on the arm-tie (5), water in the hydraulic pressure cavity flows to oil hydraulic cylinder through hole for back flow (19), and (2) Xia Duan And discharges, and the pressure in the chamber greatly reduces.Because the pulling force of feed pressure and staff pulls up piston (4) and screw elements (seeing accompanying drawing 1) such as (14) simultaneously, feedwater flow promptly flows out ， And by valve port has water slowly to flow in the hydraulic pressure cavity through the through hole of screw (14) and the inlet opening (18) of piston (4) simultaneously.Spring this moment (7) has been subjected to force compresses, after the operator lets go, spring (7) is upheld immediately, its masterpiece is used in presses on the arm-tie (5), presses arm-tie (5) to move downward, two roundlet conehead sealing hole for back flow (19), feedwater flow continues slowly to flow in the hydraulic pressure cavity through inlet opening (18), because under the pressure of spring (7) and the effect of water pressure of feedwater itself, seal ring parts such as (16) sealing valve port stops to supply water.Valve is generally closed after through-flow 7～10 seconds automatically in feedwater.(seeing accompanying drawing 2).Realize supplying water at regular time and quantity, reach the purpose of water saving.When manufacturing and designing, hole for back flow (19) total sectional area is greater than inlet opening (18) sectional area.Hydraulic pressure cavity inner carrier (4) sectional area is greater than the sectional area of valve port.
