Abstract

The utility model relates to an eccentric wheel hand operated valve, which mainly comprises a handle, a top cover, a bracket, a valve body, a sliding rod, a washer, a tightening screw, a springing and pushing device, etc. The structure of the utility model is characterized in that the handle is composed of an eccentric wheel which is composed of two internally tangent semi circles with different diameters and an arm; the structure of the eccentric wheel is characterized in that the eccentric wheel has a function on the sliding rod (a valve core) for opening and closing. The utility model has the advantages of opening in high speed, water sources saving, good tightness, accurate positioning, high durability, novel structure, simple structure, maintenance without disassembling from a pipeline, etc.

Description

The eccentric wheel hand control valve

The utility model relates to a kind of eccentric wheel hand control valve.

At present, valve of a great variety, and it is most of similar, generally all adopt left rotation and right rotation to reach the Push And Release of valve, the size of controlled water flow amount, because frequent the use, make and friction takes place between the inner member of valve cause wearing and tearing and leak, the generation gap such as the seal ring at the ball that resembles ball valve and two ends frequently rotates friction and leaking; And for example the flat position on groove on the sphere and the driving lever frequently moves back and forth, and makes both become the variation of inside and outside circle shape, not only leaks, and loses function and can not use.The valve of such class also exist switching time long, can not in opening-closing process, accurately locate self-locking, go down to waste the water source for a long time like this, in addition, the valve that is contained on the pipeline generally repairs difficultly, remove from pipeline, and is very inconvenient.

Task of the present utility model provides and a kind ofly opens and closes that speed is fast, accurate positioning, good airproof performance, eccentric wheel hand control valve durable in use, easy to maintenance.

The utility model is realized by following technical solution.

The eccentric wheel hand control valve comprises pin, handle, top cover, support, seal ring, valve body, sliding bar, packing ring, piece together tight screw, play apical organ, nut, its structural feature is: handle by the inscribe semicircle of two different-diameters form depart from the wheel and arm constitute, its eccentric axle center is done dead axle by pin and is contained on the support of being fixed by top cover, and can make it rotate 180 ° of angles around dead axle, eccentric more than half circular arc portion with match by the sliding bar top of top cover central shaft cavity, its inside of top cover is provided with the seal ring by the tight screw means of assembly that cooperates with sliding bar, its top is provided with the bullet apical organ, cooperate with the nut at sliding bar top, the sliding bar bottom is in the valve cavity, and packing ring is equipped with in its lower end, seal ring is as valve.

Below in conjunction with accompanying drawing the utility model is further described.

Accompanying drawing 1 is a faucet valve example structure schematic representation of the present utility model.

As shown in the figure, this faucet valve mainly is made up of pin 1, handle 2, top cover 3, support 14, seal ring 4,7,9,11, valve body 5, sliding bar 6, packing ring 8, the tight screw 10 of assembly, bullet apical organ 12, nut 13.Its structural feature is that eccentric wheel and the arm that handle 2 is made up of the inscribe semicircle of two different-diameters constitutes, and its eccentric wheel axle center is contained on the support of being fixed by top cover 3 14 for dead axle by pin 1, and can make eccentric wheel handle 2 rotate 180 ° of angles around dead axle.Eccentric more than half arc part cooperates with sliding bar 6 tops by top cover 3 central shaft cavitys.Top cover 3 inside be provided with cooperate with sliding bar 6 by piecing together the seal ring 11 that tight screw 10 screws, its top is provided with and plays apical organ 12, cooperate with the nut 13 at sliding bar 6 tops, sliding bar 6 bottoms are in valve body 5 cavitys, and packing ring 8, seal ring 7,9 are equipped with as valve in its lower end.

When using in the faucet valve access water route, eccentric wheel handle 2 is rotated to counter clockwise direction, change along with the top point of action of more than half circular arc of eccentric wheel and sliding bar 6, under seal ring 7 effects and bullet apical organ nut 13 effects to sliding bar 6 tops of hydraulic pressure to the sliding bar lower end, sliding bar 6 is ejected, and valve is opened, the current direction outlet port, eccentric wheel can stop in 180 ° of angular regions everywhere, is parked in diverse location, the different water yields is just arranged and go out water speed.When eccentric wheel handle 2 when clockwise direction rotates, eccentric wheel overcomes hydraulic pressure and plays the active force of apical organ, and sliding bar 6 is driven between valves (seal ring 7) close, water stops to flow out immediately.

In sliding bar 6 course of action, it only with the seal ring 11 relative close-fittings that are located at top cover 3 inside, with support, piece together tight screw 10 and do not rub.Therefore, inter deterioration is less, and sealing is strong, in case seal ring 11 wear downs, the situation of leaking does not need whole valve is pulled down from pipeline, has only top cover 3 is screwed out valve body 5, with regard to replaceable seal ring.

Under the constant situation of the utility model agent structure, also can make other various embodiments or the embodiment who describes in the specification is made all changes, but they will belong to protection domain of the present utility model.

From as can be known above-mentioned, the utlity model has keying speed fast, save water source, good airproof performance, location Accurately, durable in use, the advantage such as novel structure is simple, and is easy to maintenance.
