Abstract
The utility model relates to a water tap which is composed of a handle, a valve body, a valve rod, a sealing ring, a tap body, a pin, a gasket, and a sealing gasket. The valve body and the valve rod are matched with each other by screw threads, and the matching length is larger than the half of the two matching face; the lower part of the valve rod is provided with a sealing ring. The water tap has the advantages of simple structure, low cost, and long service life, and the utility model is not easy to leak the water.
Description
The utility model relates to a kind of water tap.
Though the water tap kind that present numerous people use is many, most service time, seepy question promptly appearred in length, and many for this reason people have done many effort at the transformation water tap leakage on inscribing, and patent 962028436 had once disclosed a kind of save-water faucet.This water tap is by set screw, valve rod, water proof pad, O-ring seals, deflating cap, valve stem casing, total, the valve core housing of valve, parts such as centering washer, sealing gasket, valve body, spring, bending moment screw thread, screens pilot pin are formed, the top of the valve body of this water conserving tap and middle part are equipped with valve stem casing and valve core housing respectively, valve rod is contained in the valve stem casing, the bending moment screw thread is arranged on the valve rod, pilot pin is fixed on the valve stem casing 5, and spool 7 is contained in valve rod 2 and the valve core housing 9, and a spring is arranged at total 7 bottoms of valve.This water tap has played the leakproof effect, but its complex structure cost height, the purpose of this utility model provide a kind of simple in structure, cost is low, the water tap of long service life.
The utility model is to realize like this, it is by handle, valve body, be contained in valve rod and seal ring in the valve body, and faucet body, put in the faucet body and be fixed on the pin in the stem lower portion endoporus and place pad and sealing gasket on the pin, and valve body and valve rod are screw-thread fit, and the length of its screw-thread fit is greater than 1/2 of fitting surface length between the two, and the seal ring that is complementary with this place's valve block internal diameter size is equipped with in the screw thread bottom on the screw rod.
The pin of this water tap cooperates for movable with the endoporus of valve body lower portion, and the length of pin is greater than sealing gasket range in water nozzle.
Owing to the utility model parts are less, and one section long screw-thread fit is arranged between valve rod and the valve body, and seal ring is arranged again under screw thread, therefore both prevented from upwards to emit, prevented that also screw thread is soaked in water for a long time and damaged on the valve rod by the water of water nozzle.Because the pin in the water tap cooperates for movable with the endoporus of valve body lower portion, therefore, when turning valve rod, can rotate under pad and the sealing gasket again thereupon,, prolonged its working life so reduced they and the friction of parts on every side.
Below in conjunction with accompanying drawing and embodiment the utility model is described further again.
Fig. 1 is embodiment 1 a sectional view
Fig. 2 is pin and a pad among the embodiment 2, structural representation between the sealing gasket
Embodiment 1:
Present embodiment valve body 2 as shown in Figure 1 is connected with water nozzle 8, water nozzle 8 links to each other with water pipe, and the valve rod 3 of upper end band handle 8 is housed in valve body 2, is screw-thread fit between valve rod 3 and the valve body 2, this screw thread adopts the fine thread at 60 ° of angles, and the length of thread engagement of screw thread is 1/2 of both fitting surface length.
On valve rod 3 bottom of screw thread have circular groove 3 ', seal ring 4 be contained in circular groove 3 ' outer wall on, valve rod 3 bottoms have endoporus 5 ', pin 5 upper ends be contained in endoporus 5 ' in, both are movable the cooperation, the pin bottom is equipped with pad 6 and is had certain flexibility or flexible sealing gasket 7, and the lower end diameter of pin 5 makes pad 6 and sealing gasket 7 be difficult for taking off greater than the endoporus of sealing gasket 7.The length of pin 5 arrives endoporus 5 ' top sum H greater than the stroke L of sealing gasket 7 in water nozzle 8 less than sealing pad 7 bottom surfaces.
Embodiment 2: the screw thread that cooperates between valve body 2 and the valve rod 3 in the present embodiment adopts trapezoidal thread, its screw-thread fit length is 3/4 of both fitting surface length, pad 6 is connected as a single entity with pin 5, one screw thread is arranged at the pin bottom, sealing gasket (7) is by nut 7 ' be fixed under the pad 6, and the length of pin 5 equals the bottom surface of sealing gasket 7 to endoporus 5 ' top sum H.Other structures are identical with embodiment 1.
