Abstract
The invention provides a trickle control valve. The trickle control valve comprises a valve body, a valve element and an adjustment block. The valve element and the adjustment block are arranged in a cavity of the valve body in a sleeved mode. A water inlet is formed in the middle of the valve element and is communicated with a water inlet pipe. The water outlet side of the water inlet is blocked through the adjustment block. An adjustment hole communicated with the water inlet is formed in the middle of the adjustment block. The water outlet end of the adjustment hole is blocked through an end cap. A spring is connected between the end cap and the wall of the adjustment hole. The portion, located on the water outlet side of the adjustment hole, of the valve body is further communicated with a water outlet pipe. According to the trickle control valve, the flowing speed of water flowing into the cavity of the valve body from the water inlet pipe can be lowered, trickles can be formed by water through distribution of the end cap, in this way, it can be guaranteed that the flowing speed of water flowing out of a faucet is lowered, and water is saved.
Description
Technical field
The invention belongs to valve field, especially relate to a kind of water tap flow control valve.
Background technique
The washbasin of public place adopts infrared-sensing type water tap usually; to realize throttling; reduce the waste of water resources; but the water flow of water tap can only realize regulation and control by the mode screwing switch; when not there are flowing out, user cannot judge the current water flow screwing the switching position and allow, and therefore often there will be and screws switch when infrared switch is opened and be in maximum flow of water amount state; water discharge of water faucet amount is huge, waste great lot of water resources.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of trickle control valve, and the water tap being applicable to public place controls, and can provide the water outlet of trickle formula, saving water resource.

Wherein, the top of regulating block is connected with adjustable lever, and adjustable lever passes valve body and above pull-up regulating block to water inlet, can be provided with the space for regulating block motion in the body cavity of valve body.
Further, the surface of contact of spool and regulating block is provided with the guide groove and guide block that cooperatively interact.
Further, the hole wall of water inlet is provided with helical drainage trough.
Further, plug is set to spherical shape, and the diameter of plug is greater than the diameter of adjustment hole.
Further, the hole heart line of water inlet and adjusting hole overlaps.
The advantage that the present invention has and good effect are:
1, trickle control valve provided by the invention can reduce to flow into the endoceliac flow rate of water flow of valve body from intake pipe, and current can form trickle shape thread through the shunting action of plug, therefore can ensure that the flow rate of water flow that water tap flows out reduces, using water wisely.
2, adjustable lever can drive on regulating block and move, adjustment hole and plug are disappeared to the inhibition of current, larger water flow can be provided, the water output of keeping a public place clean can not be affected, and regulating block only need be pressed to the water outlet position of water inlet by cleaning worker after using, namely can switch to trickle pattern, convenient and swift.
The hole wall of 3, water inlet is provided with helical drainage trough, and current are through water inlet, and helical drainage trough can play the effect of deceleration drainage, and current post can be defined as helical, when impacting plug, and trickle better effects if.

Embodiment
Below in conjunction with accompanying drawing, specific embodiments of the invention are elaborated.
As depicted in figs. 1 and 2, a kind of trickle control valve, comprise valve body 1, spool 2 and regulating block 3, spool 2 and regulating block 3 are sheathed in the body cavity of valve body 1, water inlet 4 is provided with in the middle part of spool 2, water inlet 4 is communicated with intake pipe 5, regulating block 3 is plugged in the water outlet side of water inlet 4, the middle part of regulating block 3 is provided with the adjustment hole 6 through with water inlet 4, the water outlet end shutoff of adjustment hole 6 has plug 7, be connected with spring 8 between the hole wall of plug 7 and adjustment hole 6, valve body 1 body cavity of adjustment hole 6 water outlet side is also communicated with outlet pipe 9.
Switch-linear hybrid has intake pipe 5 place, when the switch is opened, current flow into the adjustment hole 6 of regulating block 3 through the water inlet 4 of spool 1, water impact plug 7, and plug 7 is pushed away the water outlet of adjustment hole 6 by the pulling force overcoming spring 8, current are flowed out, and current are divergent shape through the shunting action of plug 7, and therefore current can be changed into trickle shape and flow out from outlet pipe 9.Trickle control valve provided by the invention can reduce to flow into the endoceliac flow rate of water flow of valve body 1 from intake pipe 5, and current can form trickle shape thread through the shunting action of plug 7, therefore can ensure that the flow rate of water flow that water tap flows out reduces, using water wisely.
As shown in Figure 3, in order to adapt to the demand of different users, as cleaning worker may need the current of larger flow velocity, with provide higher scouring force or faster speed obtain and to keep a public place clean the required water yield, in one embodiment of the present of invention, the top of regulating block 3 is connected with adjustable lever 10, and adjustable lever 10 passes valve body 1 and above pull-up regulating block 3 to water inlet 4, can be provided with the space of moving for regulating block 3 in the body cavity of valve body 1.Like this, when cleaning worker uses water tap, can move on regulating block 3, the inhibition of adjustment hole 6 and plug 7 pairs of current disappears, larger water flow can be provided, the water output of keeping a public place clean can not be affected, and regulating block 3 only need be pressed to the water outlet position of water inlet 4 by cleaning worker after using, namely can switch to trickle pattern, convenient and swift.
In the present embodiment, adjustment hole 6 and the state of water inlet 4 conducting can be returned in order to ensure that regulating block 3 moves up and down in process, spool 1 and the surface of contact of regulating block 3 are provided with the guide groove 31 and guide block that cooperatively interact.Like this, in pull-up and when pressing down regulating block, can ensure that it moves along guide groove 31, regulating block 3 can return back to original state smoothly, i.e. adjustment hole 6 and water inlet 4 conducting.
As shown in Figure 3, in order to improve the trickle effect of current further, in one embodiment of the present of invention, the hole wall of water inlet 4 is provided with helical drainage trough 11.Current are when water inlet 4, and helical drainage trough 11 can play the effect of deceleration drainage, and current post can be defined as helical, and when impacting plug 7, dissipating effect is better, and then the trickle better effects if of outlet pipe 9.
In an alternative embodiment of the invention, plug 7 is set to spherical shape, and the diameter of plug 7 is greater than the diameter of adjustment hole 6.During water impact spherical shape plug 7, shock surface is arc surface, is more conducive to the dispersion of current; The diameter of plug 7 is greater than the diameter of adjustment hole 6, and current are larger through the dispersion angle of shock surface, can further improve trickle effect.
In order to ensure that the impact force stepless action of current to plug 7 is on plug, in one embodiment of the present of invention, the hole heart line of water inlet 4 and adjusting hole 6 overlaps.Can ensure that the impact force of current vertically acts in the cambered surface of plug 7 like this, thus ensure plug 7 pairs of current dispersion effect evenly.
Above one embodiment of the present of invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the present patent application scope change and improve, and all should still belong within patent covering scope of the present invention.
