Description
The utility model relates to the durable water tap on the water supply pipe in a kind of daily life, and it also can be used for the control of other liquid.
In the prior art, most of water taps adopt metallic material to make, its seal water structure mostly is rotary spool and compresses rubber ring and come water shutoff, the long-time use can produce corrosion phenomena, rubber ring makes that it occurs dripping, water leakage phenomenon because rotation friction damages easily, and keying speed is slow, also make the hydraulic pressure instability of water pipe, produce vibration and make a noise.No. 972348719, Chinese patent disclosed " induce and carry " by the formula energy-saving tap, it is the cylindrical spool that is mounted with band conical nose moving up and down in valve body, the valve rod lower end on spool top is connected with the circular plug that opens and closes, and the upper end of valve rod is connected with carrying handle, the chock plug that opens and closes plug can compress the through hole that the poppet shaft center is offered, and the conical head of spool can compress valve seat, is provided with the protection filter bowl in the valve body in addition around spool.Though it adopts hydraulic pressure to carry out water shutoff, changing three joint spools is two joint spools, and its structure is still complicated, and adopts pressure-raising mode switch water tap up and down, and is different with common rotary switch mode, if this switch of careless rotation is easy to cause switch to damage.
The purpose of this utility model aims to provide a kind of hydraulic pressure water shutoff, durable water tap simple in structure, consistent with common rotary switch mode of utilizing, to overcome the deficiencies in the prior art part.
A kind of durable water tap by this purpose design, comprise the valve body that is provided with entery and delivery port, the valve body upper end is connected with hollow valve seat, be provided with taper valve core in the valve seat, the upper end of valve seat is connected with switching knob, its structure characteristic is that described taper valve core is an integrated type, and the bottom of spool can be pressed on the seal ring of valve seat water outlet, and the top valve stem tip is connected with the inner cap of switching knob; The outer surface of described hollow valve seat is provided with the guiding arc groove; Described switching knob endoporus is provided with small boss, and small boss inserts in the guiding arc groove, and can rotatablely move up and down along the guiding arc groove, drives spool simultaneously and moves up and down, to realize the switch water tap.
Described guiding arc groove is generally the twin-feed spiral groove.The small boss of described switching knob is generally and is symmetrical arranged, and is 2.
The utility model changes original three joint spools, two joint spools into integrated type one joint spool, and the quantity of mould and part reduces, and structure is simpler, and processing, assembling are more convenient, and cost reduces; The pressure-raising on-off mode is the left rotation and right rotation on-off mode about changing, and meets common switch custom, and water yield control is convenient; Utilize the hydraulic pressure water shutoff, Sealing is not easy to wear; This water tap adopts engineering plastics to make, and can not get rusty, and is tough and tensile durable.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an example structure schematic representation;
Fig. 2 is the structural representation of Fig. 1 hollow core valve seat;
Fig. 3 is the left view of Fig. 2.
Fig. 4 is the A-A sectional drawing of spool among Fig. 1.
Fig. 5 is the plan view of spool among Fig. 1.
Fig. 6 is the axial section of M shape seal ring among Fig. 1.
Referring to accompanying drawing, valve body 16 is horizontal T shape, and the upper end screw thread is connected with hollow valve seat 11, constitutes the water shutoff cavity with valve body.The upper end of valve seat 11 is connected with switching knob 3.Valve body 16 lower end screw threads are connected with water outlet 15.Unload the water nozzle that water nozzle can connect other, as washing machine water nozzle, intubate water nozzle etc.Valve body 16 inner chamber water outlet places are provided with a boss, the big rubber ring 13 of bowl-type is set on the boss, taper valve core 9 is pressed on the big rubber ring 13, and trim ring 8 and cross section were the seal ring 6 of M shape in the top of hollow valve seat 11 was provided with, and the valve rod of described spool 9 runs through the aperture of seal ring 6 central authorities.The valve stem tip of spool 9 is connected movingly with the inner cap 4 of switching knob 3, and knob 3 also is to be connected movingly with inner cap 4.The outer surface of hollow valve seat 11 is provided with two guiding arc grooves 18, switching knob 3 endoporus are symmetrical arranged two small boss 7, small boss inserts in the guiding arc groove 18, and the endoporus that switching knob 3 is inserted on the top of hollow valve seat 11 connects movingly, and by collar 5 positioning and fixing.Switching knob 3 can rotatablely move up and down along the guiding arc groove, drives spool 9 simultaneously and moves up and down, to realize the switch water tap.The axial cross section of the cylindrical spool 9 of present embodiment is approximate " mountain " font, the uniform location wing 19 in lower end, and the bottom is conical.
The water inlet of this water tap is provided with the barrel-shaped filter screen 17 of awl, to filter entry, reduces odds and ends and flows into, and prolongs the life-span of inner rubber seal ring.The water outlet place is provided with filter screen 14, carries out double filtration.Water outlet 15 internal diameters are cylindric, so that insert with the isometrical tube of glue of its internal diameter, press water outlet 15 inwalls because the effect of hydraulic pressure can make sebific duct expand after the water flowing, and can not come off.12 is O-ring seals among the figure, and 10 is ring, to hide the pipe thread that exposes; 1 is that top cover, 2 is the switching knob top cover, trademark can be set therebetween.
During boiling water, switching knob 3 drives spools 9 and moves upward, and the pressure of current rushes at the top of valve seat 11 fast to spool 9, realizes quick boiling water.When closing water, switching knob 3 moves downward, and switching knob top cover 2 forces valve rod and spool 3 to move downward, and at this moment, valve body 16 has been full of water with the cavity that valve seat 11 is formed, because the effect of hydraulic pressure compresses the big rubber ring 13 of bowl-type to spool 9, thereby realizes the hydraulic pressure water shutoff.
This water tap appearance is airflow design, and except that seal ring, all part is made by engineering plastics.
