Description

Push type water tap

The utility model belongs to technical field of taps, is a kind of push type water tap.

Existing water tap, all adopt handle (or handwheel) rotation to open or close current, and water tap is a public contactant, especially hospital, public place are used to wash one's hands, go to grab faucet handle with dirty palmar aspect, polluted handle, wash when turning off the tap behind the hand, palmar aspect is difficult for palm is cleaned again by the handle secondary pollution.

The purpose of this utility model is that a kind of push type water tap will be provided, as long as click the water tap push rod with finger or the back of the hand, water tap is just opened, clicking water tap more just can close, so can reduce contacting of palmar aspect and water tap when opening or closing the fire hose, clean place, any position with palm contacts with water tap, avoids palm to be secondary polluted, and keeps the water tap place clean, sanitary.

The purpose of this utility model realizes with the following methods.The push type water tap, comprise valve body, spool, gland, valve seat, water intake, water outlet, two seal rings are arranged on the cylindrical spool, spring support is installed on valve seat, the spring that is installed on the spring support supports spool, and spool top is equipped with the button type height two position switch mechanisms of pushing spool.When spool was shifted the lower position onto, then water tap was closed, and when spool was got back to the eminence position, then water tap was opened.The utility model will be further described below in conjunction with embodiment's accompanying drawing.

Fig. 1 the utility model plan view;

Fig. 2 is that the A of Fig. 1 is to view;

Fig. 3 is the K-K sectional view of Fig. 1;

The local unfolded drawing of Fig. 4 button type height two position switch mechanisms.

Among the figure: 1-valve body, 2-spool, 3-slide core, 4-guide sleeve, the 5-push rod, 6-gland, 7-seal ring, 8-spring support, the 9-valve seat, 10-Flow-rate adjustment plug, 11-spring, the 12-water intake, 13-water outlet, 14-convex tendon, the 15-convex shoulder, 16-guiding groove, 17-circular groove, I, III-sawtooth inclined-plane, II-sawtooth vertical plane, IV, V-chevron tooth inclined-plane.

Button type height two position switch mechanisms are by slide core (3), guide sleeve (4), push rod (5) is formed, slide core (3) is by round bar, single face wedge shape convex tendon (14) constitutes, the lower end of round bar is supported on the upper-end surface of spool (2), insert in the circular hole of guide sleeve (4) upper end of round bar, guide sleeve (4) is cylinder fork claw-like structure, the end face of each pawl is two sawtooth, a facewidth, a tooth is narrow, the convex tendon (14) of slide core (3) is inserted in the guiding groove (16) between the pawl of guide sleeve (4) or with the end face of pawl and contacts, push rod (5) upper end is a cylindrical bar, the lower end is cylindric, there is convex shoulder (15) outside, the cylinder end face is the chevron tooth, insert in the circular hole of guide sleeve (4) lower end of push rod (5), convex shoulder (15) is clipped in the guiding groove (16) between the pawl of guide sleeve (4), and the radial length of the convex tendon (14) on the slide core (3) is more than or equal to push rod (5) lower end chevron tooth radial thickness and guide sleeve (4) lower end cylinder pawl radial thickness sum.Inner chamber at valve body (1) has the circular groove (17) that links to each other with water intake (12), and groove depth 0.5-2 millimeter, the wide width with water intake (12) of bottom land equate, 15 °-45 ° of groove both sides chamferings.The effect of circular groove (17) is to help spool (2) up and down during slippage, reduces the wearing and tearing of seal ring (7) through this fragment position of water intake (12) time, prolongs the working life of seal ring.Seal ring (7) generally adopts the rubber manufacturing.For ease of adjusting the water yield, below the spring support (8) that water outlet (13) is located, Flow-rate adjustment plug (10) is installed.Spring support (8) and Flow-rate adjustment plug (10) are in the central position and be evenly distributed with osculum all around, when both osculums align, and the water-outlet quantity maximum, when the osculum around both all misplaced, the water-outlet quantity minimum had only the center hole water outlet.Therefore the big or small only with hand rotary current adjusting plug that adjusts the water yield gets final product.The upper end of guide sleeve (4) is a flange, and pressured lid (6) is pressed on the end face of valve body (1).

Working principle of the present utility model is as follows.State shown in Figure 1 is the water tap opening state, and water flows out through valve body (1) inner chamber and water outlet (13), Flow-rate adjustment plug (10) from water intake (12).When closing water tap, as long as press lower push-rod (5) with hand, this moment, the chevron tooth inclined-plane (IV) of push rod (5) lower end overcame upwards active force of spring (11), the convex tendon (14) that promotes slide core (3) downwards moves down, because the leading role of convex tendon (14) and guiding groove (16), slide core (3) can only move and can not rotate, but when slide core (3) moves down a segment distance to the chevron flank of tooth when concordant with the zigzag fashion flank of tooth of guide sleeve (4) lower end, convex tendon (14) has broken away from the effect of contraction of guiding groove (16), spring (11) forces 15 °-45 ° of the angles of wedge on the slide core (3) by spool (2) single face wedge shape convex tendon (14) is along chevron inclined-plane (IV) slide (shown in Figure 4), convex tendon (14) is stuck in two the chevron flank of tooth (IV, the concave bottom place of position, boundary V), slide core (3) has been rotated an angle like this, rely on convex tendon (14) to be shelved on the sawtooth inclined-plane (I) of lower end of guide sleeve (4), when people's hand leaves push rod (5), be after push rod (5) is gone up downward active force disappearance, spring (11) forces the convex tendon (14) of slide core (3) to continue to slide into the sawtooth vertical plane (II) of convex tendon (14) near guide sleeve (4) lower end along sawtooth inclined-plane (I) by spool (2), slide core (3) has been rotated an angle again like this, twice rotation angle sum is π/n(n=3,4,5 ... be guide sleeve cylinder fork pawl number, present embodiment n=4 promptly changes 45 °), this moment, spool moved down a segment distance, spool (2) is moved down into stop up water intake (12), two seal rings (7) divide the both sides up and down that are in water intake (12), play good seal action.Water tap is closed like this.In like manner applying external force once more makes push rod (5) when moving down, the promotion of convex tendon (14) on push rod (5) chevron tooth inclined-plane, lower end (IV) of slide core (3) moves down, after external force disappears, convex tendon (14) promotes under the mating reaction of spool (2) at spring (11), convex tendon (14) is got back in the guiding groove (16) after sawtooth inclined-plane (III) slides again, thereby moved, open water intake (12) on the spool.Therefore, in sum, water tap is closed or open as long as push a lower push-rod (5).

The utility model is simple in structure, switch is convenient, clean hygiene, can reduce the secondary pollution of palmar aspect, is suitable for family, hospital, and particularly the public place uses.
