Description
Technical field
The utility model relates to the bath articles field, relates in particular to a kind of time-delayed self-turning off tap spool.
Background technique
The time-delayed self-turning off tap that uses at present, mostly adopt fixed groove or aperture to make time-delay water storage cavity intake tunnel technique, it is downward to press handwheel drive water storage cavity inner carrier, under Water Pressure, piston and connecting rod hermetic separation, discharged fast the water in the chamber, after loosing one's grip, pressing under Returnning spring and piston reset spring act on simultaneously, piston and connecting rod seal closure, the piston water that moves up is inhaled into water storage cavity from fixed groove or aperture, water plays damping function, piston can only slowly move up, behind the certain hour, and throttle down when piston rises to valve body sealing face.Though such water tap can realize prolonging function of self closing, but make time-delay water storage cavity intake tunnel technique owing to adopted fixed groove or aperture, delay time was long when hydraulic pressure was low, delay time was too short when delay balance spring hydraulic pressure was high, delay time is non-adjustable, and it is too short to be difficult to control delay time batch conformity and whole delay time.
Summary of the invention
The utility model is in order to overcome the defective of prior art, and purpose is to provide a kind of time-delayed self-turning off tap spool, and can regulate as requested length and the weak point of delay time.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of time-delayed self-turning off tap spool, comprise that pressing of arranging on valve body, the valve body is provided with in handwheel, the valve body and presses the connecting rod of pressing that handwheel cooperates, be provided with in the described valve body and be placed in the spring support of pressing on the connecting rod, spring support and press to be provided with between the handwheel and press Returnning spring; Be provided with in the described valve body and can protect the stable delay adjustment device of whole delay time, delay adjustment device by water storage cavity, time-delay adjustment seat, be located at the water storage cavity piston of time-delay in the adjustment seat, with time-delay that the water storage cavity piston cooperates in accent screw and the balance spring that is placed on the water storage cavity piston form.
Aforesaid time-delay adjustment seat is the two-stage cylindrical structural and is provided with the counterbore step and the center via hole that time-delay adjustment seat front end large cylinder is that outside thread is connected with the internal thread of valve body, and is provided with the sealing of O type circle; The rear end small cylinder is provided with the water storage cavity intake tunnel.Third level cylinder plays fixing spring and position-limiting action, and outer rim has seal ring, and integral body is placed on the time-delay adjustment seat counterbore step, and with transferring screw to fix in the time-delay, forms the water storage cavity intake tunnel.
Aforesaid water storage cavity piston is three grades of cylindrical bodys that place on the counterbore step of time-delay adjustment seat, and prime cylinder external diameter is less than time-delay adjustment seat center via hole; Second level cylinder has the delay balance spring than the time-delay adjustment seat center large also cover of via hole, and the end face of second level cylinder is provided with chamfering.
Transfer screw to be provided with the hydraulic pressure that links to each other with the water storage cavity piston in the aforesaid time-delay and detect the hole.
Aforesaid bottom of pressing connecting rod is connected with piston rod, and the bottom of piston rod is connected with piston, and piston is provided with piston reset spring, is provided with lip-type packing between piston and the valve interior wall.
Aforesaid water storage cavity is complemented each other to form by piston, valve body, time-delay adjustment seat, water storage cavity piston.
Aforesaid valve body is provided with water intake and water outlet, is provided with the water-inlet cavity that is communicated with water intake and the water chamber that is communicated with water outlet in the valve body.
Also be provided with guiding in the aforesaid valve body and decide screw and decide the hexagonal spigot nut of screw fit with guiding, the hexagonal spigot nut is connected with piston.
Also be provided with on the aforesaid valve body and be positioned at the outer adjusting nut of pressing the handwheel below.
The aforesaid internal thread connecting end cylindrical of pressing connecting rod adopts inverted cone-shaped structure.
Transferring in the described time-delay has hydraulic pressure to detect the hole on the screw, link to each other with the water storage cavity piston, but the overall delay time of manual tune, regulate clockwise, delay time increases, regulate counterclockwise delay time and reduce, because reaction force and the water storage cavity piston third level cylinder position-limiting action of balance spring, the water storage cavity intake tunnel remains a fixed gap.When hydraulic pressure was high, balance spring was compressed, and the water storage cavity piston forward moves, and the intake tunnel useful area reduces, and delay time increases; When hydraulic pressure hanged down, balance spring resetted, and the water storage cavity piston is mobile in the other direction, and the intake tunnel useful area increases, and delay time shortens; Can keep time-delay basicly stable.Outside valve body, outer adjusting nut is arranged, also can regulate delay time, to regulate clockwise, delay time increases, and regulates counterclockwise, and delay time reduces, and when being conducive to produce in batches, keeps the conformity of delay time.Press connecting rod internal thread connecting end and adopt reversed structure, to reduce the impact of hydraulic pressure, improved the stability of delay time.
In sum, time-delayed self-turning off tap spool of the present utility model spool compared to existing technology, can realize prolonging function of self closing, delay time is adjustable and stable, is easy to control the conformity of delay time and the stability of whole delay time, no matter when hydraulic pressure height or hydraulic pressure are low, the conformity that can both keep delay time, reduce the impact of hydraulic pressure on this spool, improved the stability of delay time, can also regulate by user's requirement the time of time-delay closing.
