Description

Step positioning type faucet with auto-lock function

Technical field: the invention belongs to the control valve for fluids technical field of structures.

Background technique: current, human development and existence seriously are subjected to the puzzlement of water resources, no matter are the development in city, industrial expansion, and water resources all plays vital factor.But the waste of water but is very surprising, particularly in domestic water, the waste of water is high especially as to make us inconceivable, the water yield of waste is used much higher more than real life, its main cause is that there was certain problem in the traditional concept in the water tap design originally, the tap that uses is the tap of involute at present, and expression is Q=K (t) φ V on mathematics, the Q-flow, K (t)-aperture, φ-caliber, V-speed, wherein φ, V can think constant, and K (t)=Ct, the C aperture is a speed, t is the time, because being screw thread or bulb rotation, existing old-fashioned tap regulates aperture, therefore, the flow size can be adjusted arbitrarily and locate, and opening process is a linear scale function (being that liquid output amount is a linear scale function).Promptly adjust aperture and location by rotatable handle.The K value of tap can be fixed in arbitrary aperture, and the rotation of water meter is to have certain blind area, and water meter is difficult to reflect and can not rotates under certain small flow situation.Show that according to statistics only the annual evaporating, emitting, dripping or leaking of liquid or gas in Beijing water yield of losing just is equivalent to 13 North Sea water capacities.

Summary of the invention: purpose of the present invention provides a kind of different gear control flow rate that as required water discharge of water faucet is divided in order to overcome existing involute water tap above shortcomings part just, adopt thrust spring and taper sealing, form self-locking, fully prevent the step positioning type faucet that the small flow current lose with auto-lock function.

The objective of the invention is to realize by following technical solution:

Step positioning type faucet with auto-lock function by being fixed by spool plural position when the valve body valve pocket intrinsic displacement, forms several different water passage hole cross sections, and the water-outlet quantity that makes water tap is in position difference that each is fixed.

The present invention is provided with up-small and down-big conical cavity in the valve body valve pocket, spool is that the taper with "T"-shaped water channel places in the conical cavity of valve body; The spool upper end is connected with handle by connecting rod; The lower end is provided with a thrust spring and contacts with the compression of spool bottom; Water intake is communicated with the water hole of spool bottom; On the connecting rod of spool and handle, the rotation that the is provided with plural shelves mechanism of putting into gear, this rotation mechanism of putting into gear includes the decide gear shaft and layering and branch angle that are fixed on the connecting rod and is arranged on the gear hole that valve body valve pocket inwall is offered; Structure of the present invention also can be in the valve body valve pocket and is provided with cylindrical cavity, is provided with a step on this cavity top, and spool is the interior bottom of cylindrical cavity that a piston-like disk places valve body; The spool upper end is connected with handle by connecting rod; Being provided with a thrust spring contacts with the piston-like disk bottom compression of spool; Water intake is communicated with the cavity on piston-like disk top; On the connecting rod of spool and handle, be provided with two with the rotation of the performing mechanism of putting into gear, this rotation mechanism of putting into gear includes decide gear shaft and the layering branch angle of rotation that are fixed on the connecting rod and is arranged on gear hole in the valve pocket; By the position that is fixed when the valve body valve pocket intrinsic displacement by spool is 2～8.

Because the present invention's tap gear is controlled by the gear shaft of deciding of tap, the gear rotation that when opening water handle is depressed into requirement is suspended to gear block and gets final product, and tap is not subjected to thrust spring and water pressure (P when neutral position (putting into gear) ₀〉=P ₁) effect can close automatically, tap is in closed condition when the neutral position, and this is because it is subjected to the effect of water pressure, spring force to be in closed condition, and such design is as long as all can close automatically at neutral position water tap.When the needs boiling water, press down handle and rotation and be suspended to the gear that the needs tap of promptly can fetching boiling water, rotation neutral position gets final product when closing water.

The present invention is to be foundation according to the step function formal approach on mathematics, as required water tap is divided into different gear control flow rate, closes automatically during neutral, promptly obtains different step function form flows by the control gear, prevents that the small flow current from losing.

Because the output quantity of leading fluid is a step function (moment reaches a certain amount of), i.e. K '=1 (1/n), when n=1, K '=1, during n=2, K '=0.5 ..., the location is then determined by gear.Q＝K’φV。Determine minimum gear as required, overcome the blind area to small flow of the rotation existence of water meter, can close automatically.So the present invention mainly solves the problem of two existence: the one, prevent to have a mind to or be not intended to the waste of water resources, the 2nd, overcome the blind area that the rotation of water meter exists; The present invention is especially for having special significance in the technology of different gear control flow rate.
