top mouthfuls

24 and 25 designs of four horizontal grooves are being suppressed on the cover 7---at this moment to suppress cover 7 profiles be cylindric and four claws are arranged at mouthful 24 tops, socket top) down.After suppressing cover 7 and being installed within the socket top mouthfuls 24, plane and socket 18 upper-end surfaces it on (that is mouth 24 upper-end surfaces, socket top) are fair.Installation is suppressed after the cover 7, and the rotating shaft 30 on secondary flow valve spiral cover 6 tops is by passing in the center hole 35 that suppresses cover 7.Suppress cover 7 and not only secondary flow valve spiral cover 6 is played the effect of bearing, and have certain elastic force that presses down, the male cone (strobilus masculinus) 32 of secondary flow valve spiral cover 6 is seamlessly pressed together tightly with socket inner conical surface 23, so 6 rotatable can not sliding up and down of secondary flow valve spiral cover.It on the rotating shaft 30 of secondary flow valve spiral cover 6 one section square column 29 (referring to Fig. 4); Swing handle 8 bottom endoporus are a square hole, the latter's shape and size are in full accord with the former, and the two cooperation closely, and are fixed together by tapping screw 10 and packing ring 11, and can rotate together, so the rotation of secondary flow valve spiral cover 6 is carried out by rotating swing handle 8.Leave the gap about 0.5mm between swing handle 8 lower end surfaces and socket 18 upper-end surfaces, in order to avoid the two mutual friction.The rotation angle of secondary flow valve spiral cover 6 is limited, because the fan shape limiting stopper 21 of a smaller angle is arranged on the socket inner conical surface 23, and a fan shape restraining groove 34 than wide-angle is arranged on the male cone (strobilus masculinus) 32 of secondary flow valve spiral cover 6, after installing together, limiting stopper 21 just in time places in the restraining groove 34, the difference of the two angle be secondary flow valve spiral cover 6 rotating maximum angles (also can with fan shape restraining groove 34 design on socket inner conical surface 23 and with 21 designs of fan shape limiting stopper on the conical surface 32 outside the secondary flow valve spiral cover 6).Because secondary flow valve spiral cover 6 needs to rotate, therefore, it pushes up mouth 24 with socket and suppresses between the cover center hole 35 and can only take radial clearance to cooperate; For prevent that the water in the secondary flow chamber from overflowing from this matching gap, leave a seal groove on the maximum cylinder 31 of secondary flow valve spiral cover 6, a built-in O type O-ring seal 12 overflows from this matching gap to stop the water in the secondary flow chamber; Trade mark lens 9 drive fits are fitted in the round cavity on swing handle 8 tops, and screw 10 and packing ring 11 are covered wherein (referring to Fig. 1).

The utility model in off position down, secondary flow chamber exhalant canal 33 on the secondary flow valve spiral cover 6 interlaces and does not communicate with secondary flow effluent trough 26 and secondary flow osculum 27 on the socket inner conical surface 23, therefore, water in the secondary flow chamber can't flow out, so hydraulic pressure equates in secondary flow chamber and the main flow chamber, the water in the main flow chamber is unable upwards to be backed down piston 3 (comprising rubber cushion 2), and 3 in piston is under the suppressing of delaying pressing spring 4, under slide into the foot of piston slideway 20, make rubber cushion 2 block main flow water outlet 19.In off position, the cam vice division chief that control stream cam 5 and secondary flow valve spiral cover 6 are constituted is in zero engagement (the two depth of engagement is zero).When rotating counterclockwise swing handle 8, secondary flow valve spiral cover 6 rotates thereupon together, and the secondary depth of engagement of above-mentioned cam becomes greatly gradually, thereby makes between control stream cam 5 and the piston 3 apart from becoming big gradually; When turning over the angle that sets, secondary flow chamber exhalant canal 33 on the secondary flow valve spiral cover 6 and the fan shape secondary flow effluent trough 26 on the socket inner conical surface 23 communicate, and also communicate with its secondary flow osculum 27 by effluent trough 26; At this moment, the water in the secondary flow chamber just flows into Discharging bent-tubes 17 by secondary flow chamber exhalant canal 33, secondary flow effluent trough 26 and secondary flow osculum 27 and flows out, and therefore, the hydraulic pressure the secondary flow chamber in is owing to the water outflow weakens reduction, causes that hydraulic pressure is higher than the secondary flow chamber in the main flow chamber; So, water in the main flow chamber upwards backs down certain altitude with piston 3 (comprising rubber cushion 2), at this moment, the water in the main flow chamber just flows out by main flow water outlet 19 and Discharging bent-tube 17, i.e. water nozzle be opened (also can be designed to " water nozzle is opened when clockwise rotating swing handle 8 ").Piston 3 is controlled by the depth of engagement of the cam pair that the height on last top is made of control stream cam 5 and secondary flow valve spiral cover 6.When being rotated further swing handle 8, the angle that secondary flow valve spiral cover 6 turns over is just bigger, and the degree of depth of the secondary engagement of above-mentioned cam is also bigger, and apart from bigger, piston 3 is bigger by the height on last top between control stream cam 5 and the piston 3, thereby current are bigger; When the degree of depth of the secondary engagement of above-mentioned cam was the maximum value that sets, piston was maximum by the height on last top, and current are also maximum.The process of closing water nozzle is the inverse process of said process, when turning round the angle that sets, secondary flow effluent trough 26 on secondary flow chamber exhalant canal 33 on the secondary flow screw lid 6 and the socket inner conical surface 23 and secondary flow osculum 27 just miss and no longer communicate, so, the main flow chamber equates once more that with hydraulic pressure in the secondary flow chamber at this moment under the suppressing of slow pressing spring 4, piston 3 slides into the foot of piston slideway 20 once more down, and making rubber cushion 2 block main flow water outlet 19, water nozzle is closed; But swing handle 8 still has certain rotation angle, and the setting of this angle is in order to have the gageable minimum current of water meter when opening water nozzle.Be rotated further swing handle 8 until not rotating, then the cam pair formed of control stream cam 5 and secondary flow valve spiral cover 6 transfers zero engagement again to, and is at this moment, almost very close to each other between control stream cam 5 and the piston 3 again.

The utility model available metal made or plastics manufacturing.
