Description

Time-delay controllable water-saving tap

Technical field

The utility model relates to a kind of time-delay controllable water-saving tap, belongs to the water tap field.

Background technique

At present, water conserving tap on the market is broadly divided into two kinds of induction time-delay and mechanical delays, but the former cost is higher, the market price is generally more than 150 yuan, and installation and maintenance are extremely inconvenient, also can't use in the dead electricity situation, this is just so that the application of induction type water tap has larger narrow limitation; And the mechanical-type delay water faucet need not power supply, and is simple in structure, is easy to installation and maintenance, and the market price is generally between 20 to 100 yuan.Although the mechanical type delay water faucet has above advantage, but we find that in investigation the application of mechanical water-saving tap is not very extensive, main cause is that water discharging time and water-outlet quantity are fixing unadjustable, can not finely satisfy the demand of people under various different conditions.Such as following two kinds of situations: the first, when you need to connect one glass of water, water filled the not yet rebound of rear water tap, causes water resource waste.The second, when you need to connect a basin water, water tap rebound and water does not fill need to be pressed water tap repeatedly, and is extremely inconvenient.

Summary of the invention

The purpose of this utility model is the defective that overcomes prior art, provide a kind of simple in structure, can control water discharging time and the time-delay controllable water-saving that can save water and energy tap.

The technological scheme that realizes the utility model purpose is: a kind of time-delay controllable water-saving tap, comprise tap valve body and piston depression bar, the top of piston depression bar is equipped with gland, be embedded with Returnning spring in the gland, have water intake and water outlet on the tap valve body, be equipped with on the tap valve body into water and regulate cylinder and have the stuffing box gland water intake and the stuffing box gland of stuffing box gland water outlet, and the inner chamber that cylinder and stuffing box gland are regulated in water inlet is communicated with, be set with piston ring and the Sealing shield ring that can seal the stuffing box gland water intake on the piston depression bar, the inner chamber of stuffing box gland, inner chamber and piston ring that cylinder is regulated in water inlet surround a water chamber, water chamber is communicated with the water outlet of tap valve body by the stuffing box gland water outlet that is arranged on the stuffing box gland, water chamber is communicated with the water intake of tap valve body by being arranged on the adjusting cylinder water intake of regulating on the cylinder into water, form a control chamber between the inner chamber bottom of described water inlet adjusting cylinder and the piston ring, control chamber is communicated with the water intake of tap valve body by being arranged on into the regulation and control hole of water adjusting cylinder bottom section, and the lower end of described piston depression bar is connected with the back-up ring that can seal the regulation and control hole.

Further, be provided with the back-up ring holddown spring between described piston depression bar and the back-up ring, be provided with the first spring chamber in the described piston depression bar, be provided with the second spring chamber in the described back-up ring, one end of back-up ring holddown spring and the bottom surface of the first spring chamber offset, and the bottom surface of the other end and the second spring chamber offsets.

Further, the water chamber seal ring is equipped with at the position that contacts with the piston depression bar in the described stuffing box gland.

In a nearlyer step, the sealing volution is housed in the described stuffing box gland, and the sealing volution is positioned at the top of water chamber seal ring.

After having adopted technique scheme, water enters from the water intake of tap valve body, when the piston depression bar is depressed, Sealing shield ring separates with the stuffing box gland water intake, current pass through water chamber, enter the water outlet of tap valve body, thereby realize water outlet, after hand unclamps, Returnning spring drives the resilience of piston depression bar, Sealing shield ring and stuffing box gland water intake are adjacent to again, have blocked current, thereby realize cutting off the water supply, the water is just on the boil begin to be to be full of the water intake of tap valve body and control chamber, when the piston depression bar was depressed, the regulation and control orifice flow that current are regulated cylinder bottom section by water inlet in the control chamber went out, when the resilience of piston depression bar, current enter control chamber from the regulation and control orifice flow again, thereby by the adjusting that contend with realize water discharging time of the hydraulic pressure of control in the control chamber with the resilient pressure of Returnning spring, by the rotary-piston depression bar, the control back-up ring seals the quantity in hole, thereby determine the speed that current enter, the size of the hydraulic pressure in the control chamber, thereby control resilience time realize the controlled of water discharging time; The back-up ring holddown spring can make the piston depression bar no matter in any position, and back-up ring can both fit tightly with the bottom that cylinder is regulated in water inlet; Arranging of water chamber seal ring can prevent the current leakage; The sealing volution that the top arranges can compress the water chamber seal ring, further plays the effect of sealing.
