Description

The Time-delay water valve spool of a kind of adjustable time and flow

Technical field

The utility model relates to a kind of Time-delay water valve spool manufacturing technology, especially refers to the delay time and the flow regulator structure technology of spool.

Background technique

When early stage water valve product need be closed, must by manually or pin step on mode and be achieved; So when this series products is applied to public places such as hotel, restaurant, station, public lavatory, very easily forget throttle down, cause the waste of water resources thus owing to people's negligence.For this reason, people have invented a kind of time-delay spool product, and it with after common water nozzle or pipeline are connected, can be realized the automatic delay function of water valve and need not manual intervention, thus water resources that can saves valuable.This type of comparatively typical product as State Intellectual Property Office in notice of authorization on May 13rd, 2009, the patent No. is called the utility model patent technology of " a kind of time-delay control spool " for the ZL200820162618.8 name, it " comprises by press button; the spool set screw nut; described spool set screw nut below sets gradually drip irrigator and water inlet regulator; at above-mentioned spool set screw nut; drip irrigator and water inlet regulator are together stacked and be equipped with the central through bore that communicates in the center; have a valve core rod to pass and be connected by press button from above-mentioned central through bore from bottom to top, by between press button and the spool set screw nut spring being arranged, in the central through bore of spool set screw nut, be provided with seal washer, the sealing circle matches with valve core rod, on valve core rod, be provided with seal ring, the sealing circle matches with the center hole of water inlet regulator, the valve core rod bottom is set with the piston pad, the bottom of valve core rod is placed in the vacuum chamber, the above-mentioned piston pad and the locular wall of vacuum chamber closely make the bottom of valve core rod form a piston by touching, upwards have the time-delay water hole in the bottom of valve core rod, this top, time-delay water hole water outlet is positioned at the top of piston pad and below seal ring, is provided with the water outlet that communicates with central through bore on drip irrigator ".But owing to the requirement of different application places to delay time and water flow has nothing in common with each other, so the said goods obviously exists the defective and the deficiency of versatility difference.For this reason, people expect to invent a kind of Time-delay water valve spool product that can regulate time and flow easily, to improve the versatility of this series products, significantly reduce the specification and the model of product, help extensive, mass production, to reduce manufacture cost.

The model utility content

The technical problems to be solved in the utility model is to overcome the delay time of prior art products existence and defective and the deficiency that water flow is regulated inconvenience and versatility difference, provide a kind of Time-delay water valve spool product that can regulate time and flow easily to society, to improve the versatility of this series products, significantly reduce the specification and the model of product, help extensive, mass production, to reduce manufacture cost.

The technological scheme that its technical problem that solves the utility model adopts is: the Time-delay water valve spool of adjustable time and flow, comprise valve body, press button and valve rod, and be provided with Returnning spring between described press button and the described valve rod; Described valve rod lower end is socketed with out water regulator, describedly goes out the base that the water regulator lower end is socketed with afterbody tool vacuum chamber, and described base peripheral wall is provided with water intake; Described valve rod lower end stretches out in the described water regulator inner chamber that goes out, and described valve rod underpart is provided with seal ring, top cover and compact heap successively; The outer wall of described compact heap is embedded with V-shaped seal ring and described vacuum chamber inwall forms sealing; Described valve rod orate also is connected with adjustable lever; Described compact heap is provided with time-delay hole, center, and the axis body of described adjustable lever underpart is inserted in the time-delay hole, center of described compact heap.

The top that described compact heap is positioned at described V-shaped seal ring is provided with radial direction through hole, is arranged with a pair of circular hole corresponding to the described top at described compact heap radial direction through hole position.

Describedly go out the water regulator upper end edge and be axially arranged with some manger boards, the radian that adjacent two described manger boards surround increases progressively successively or successively decreases successively.

Described press button center is provided with trim.

The Time-delay water valve spool product of the utility model adjustable time and flow, by set up the mode of adjustable lever by the valve rod center, making can be by press button center portion turn adjustable lever, the axis body of realization adjustable lever underpart and compact heap center time-delay pitch-row are from variation, this effect that occurs in compact heap center time-delay interporal lacuna variable in distance, be equal to the damping of existing similar known technology product damping varying aperture fully, thereby can realize adjusting easily delay time.This product goes out some manger boards of water regulator upper end, and every pair of two adjacent radians that manger board surrounded have nothing in common with each other, and by rotating out after water regulator makes its corresponding position and the valve casing water outlet matches, can obtain different water flows.Compare than prior art products, have compact structure, reasonable in design, characteristics that volume is small and exquisite, be widely used in public places such as hotel, restaurant, station, public lavatory.
