Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, this water tap, comprises faucet body 1, is arranged on the valve rod 2 on faucet body 1, is arranged on the spool 3 under valve rod 2, and the spool chamber 4 of faucet body 1 inside is provided with the elastomer 5 be coated on outside spool 3 between spool 3 and spool chamber 4.By the flow channel 6 of water tap afterbody, water flows in faucet body 1, through being coated on the elastomer 5 that spool 3 can control water turnover, because the factors such as temperature are on the impact of faucet body 1 and spool 3, elastomer 5 is set between faucet body 1 and spool 3, is solved the problem by the contraction of elastomer 5.Spool 3 again under being arranged on handle and valve rod 2, finally flows out from the flow channel 6 of faucet body 1 front portion.
In this water tap, described elastomer 5 adopts plastic materials to make.Shunk by the elastomer 5 of plastic materials, the sealing problem between faucet body 1 and spool 3 can be solved.The plastics that its elastomer 5 adopts are PE.By PE material, improve the working life of water tap, decrease and occur that iron rust, its water quality are good, easy-maintaining, good waterproof performance and low cost and other advantages.Be provided with flow channel 6 in described faucet body 1, described spool 3 is provided with the spool bore 31 that can communicate with flow channel 6, and described elastomer 5 is provided with the springhole 51 corresponding with spool bore 31 position.Can be controlled the turnover of water by rotary spool 3, when spool 3 rotates to spool bore 31 and springhole 51 communicates, water can flow out from water tap, otherwise water can not flow out water tap.Described spool 3 is in butt inverted cone.Be less than top bottom spool 3, form inverted cone, the pressure of spool 3, elastomer 5 and faucet body 1 three surface of contact each other can be increased, thus strengthen sealing.Described spool 3 and valve rod 2 are integral type.Spool 3 and valve rod 2 are plastic materials, and therefore spool 3 and valve rod 2 can adopt integrated injection forming, ensure that valve rod 2 can be with movable valve plug 3 to rotate.The fixed cover 7 for being fixed on by valve rod 2 on faucet valve core 3 mounting hole is arranged with outside described valve rod 2.Be provided with screw thread by faucet body 1, fixed cover 7 is threaded connection and is fixed on body, is limited position between valve rod 2 and body.
In above-mentioned water tap, described spool chamber 4 inwall is provided with draw-in groove 41, and described elastomer 5 outer wall is provided with the limit rib 52 embedding draw-in groove 41.By the cooperation of limit rib 52 and draw-in groove 41, elastomer 5 is stuck on faucet body 1, the degrees of freedom of restriction elastomer 5 and the circumferential sense of rotation of faucet body 1.Described valve rod 2 is installed with banking stop 21, and described spool chamber 4 top is provided with curved limit guide groove 42, and banking stop 21 can be resisted against the two ends of limit guide groove 42 when described valve rod 2 rotates.By rotary valve rod 2, the banking stop 21 on band ovable valve stem 2 rotates on limit guide groove 42.Described limit guide groove 42 radian is 180 degree, and described banking stop 21 is the arc in 90 degree, and the arc of described limit guide groove 42 is coaxial with the arc of banking stop 21.By rotary valve rod 2, banking stop 21 also rotates, and because banking stop 21 own is in 90 degree, limit guide groove 42180 degree, so banking stop 21 is against the interior rotation in 90 degree, two ends of limit guide groove 42.Described water tap valve rod is provided with faucet handle, and described valve rod 2, spool 3 and handle are coaxial.By handle with sleeve, band ovable valve stem 2 rotates, and the spool 3 be connected with valve rod 2 integral type is also along with rotation.
The using process of this water tap is as follows:
First the flow channel 6 of water from faucet body 1 afterbody is entered, water is through being coated on the springhole 51 corresponding with spool bore 31 position of the elastomer 5 outside spool 3, arrive spool 3 place, pass through rotatable handle, handle strip ovable valve stem 2, again with the banking stop 21 on ovable valve stem 2 in the interior rotation in 90 degree, two ends against limit guide groove 42, due to the cooperation of limit rib 52 and draw-in groove 41 in rotary course, elastomer 5 is stuck in valve pocket, the degrees of freedom of restriction elastomer 5 and the circumferential sense of rotation of faucet body 1.When the spool bore 31 rotated on spool 3 and springhole 51 communicate, water can pass through spool 3, flows out from flow channel 6.Otherwise water can not flow out water tap.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
