Abstract

The utility model relates to a multi-functional water tap which is composed of a valve body and a valve core, wherein, the valve core is composed of a valve plug, a valve rod, and an eccentric crankshaft. The valve plug is a rubber plug and is positioned at the water inlet mouth of the valve body, one end of the valve rod is connected with the valve plug, and the other end of the valve rod is connected with the eccentric crankshaft by a through pin and an eccentric hole; the end of the connection of the valve rod and the eccentric crankshaft is provided with a sealing sleeve pipe, one end of the sealing sleeve pipe is tightly sheathed on the valve rod, and the end near the eccentric crankshaft is riveted on the valve body; a handle is arranged on the eccentric crankshaft. The technology of the utility model has the advantages of reasonable structure, good sealing property, simple manufacture, and low cost; when the utility model is in use, no vibration and howling happen, and the utility model also has the functions of self-closing and movable connection even without the water.

Description

Multi-function water tap

The utility model belongs to valve tap technical field, is specifically related to a kind of multi-function water tap.

In the daily life, the water tap that people use all is to close or open by rotatable handle by screw thread, and this class water tap exists screw thread stripped thread or water shutoff rubber cushion owing to current push the problem that breakage is leaked for a long time, and working life is short; Also existing in addition can not water-stopping self-closing, causes water waste, uses inconvenience.Chinese patent ZL92230936.1 discloses a kind of " the anhydrous water tap of closing automatically ", it is made of valve body, water intake, water chamber and spool, the start or stop of spool is controlled by the camshaft on the valve body, deadweight by size of the frictional force between spool and the camshaft and handle realizes anhydrous self-closing.Automatically close the effect of water tap when this technology can reach anhydrous, but still have following problem: 1. possess anhydrous self-closing function, function singleness.2. spool is with the vortex flow rotation during water flowing, and when certain pressure, water tap produces vibration, utters long and high-pitched sounds, and influences working life.3. the design of the sealing surface of valve body is between water intake and water outlet, and the manufacturing process difficulty is big, and manufacture cost exceeds 3 times of ordinary faucet.4. the design of the sealing cover between bent axle and the valve body, the frictional force when having increased crankshaft rotating does not on the one hand reach effective seal on the other hand.

The utility model is at the prior art above shortcomings, when purpose is to provide a kind of water flowing friction with utter long and high-pitched sounds, rational in infrastructure, good airproof performance, manufacturing process is simple, and cost is low, but with the multi-function water tap of anhydrous all automatic closing functions, loose joint function.

The technical solution of the utility model is as follows:

Multi-function water tap, comprise valve body and spool, valve body is established water intake and water outlet, and spool is made up of valve plug, valve rod and eccentric crankshaft, and valve plug is the water inlet that plug is positioned at valve body, valve rod one end connects valve plug, the other end is connected eccentric crankshaft by wearing pin with eccentric opening, and valve rod connects eccentric crankshaft one end and is provided with Sealed casing pipe, and Sealed casing pipe one end tightly is placed on the valve rod, on valve body, establish handle near eccentric crankshaft one end riveting knot on the eccentric crankshaft.Sealed casing pipe on the valve rod is the gum sleeve with stretchability, and valve plug is the conical surface or plane plug.When handle upwards rotates, promote valve rod by eccentric crankshaft, open plug (Open valve) by the valve rod top and discharge water, handle rotates, and retracts plug by crankshaft-link rod, promptly closes.

The utility model has the advantages that:

1. rational in infrastructure, vibrate when having solved existing anhydrous self-closing faucet water flowing, the problem of uttering long and high-pitched sounds: present technique has adopted the eccentric crankshaft structure, between valve rod and the bent axle by wearing pin and eccentric opening couples together, during water flowing, valve plug and valve rod all can not produce vibration and utter long and high-pitched sounds because of flow action, have improved the working life of water tap.

2. good seal performance: because at valve plug with valve rod has designed plug with the eccentric crankshaft connecting place and telescopic gum sleeve seals, gum sleeve one end tightly overlaps valve rod, one end then riveting knot has promptly been avoided the friction between stem movement and the sleeve pipe on valve body, have good sealing property again.Wearing and tearing have been reduced, longer service life to seal element.

3, manufacturing process is simple, cost is low: this water tap is the sealing surface of valve body, and design is in two terminations of valve body, promptly feed-water end and with the bent axle connecting end, make easily, thereby can reduce production costs.

4. but with anhydrous all automatic closing functions, extensively be suitable for the public place: because eccentric crankshaft is designed at least two eccentric opening forms that throw of eccentric is different, when valve rod connected eccentric crankshaft by the bigger eccentric opening of throw of eccentric, because throw of eccentric is big, moment was then little, handle is having the anhydrous state all can not self-locking, during water, must lift handle, can accomplish like this that the people leakes water to close with hand, avoid water waste, be widely used in the public place.

5. loose joint function: because the profile of this faucet outlet adopts taper mouth, easier connection flexible pipe, and all can normal long distance water under 6 kilograms/meter 2 pressure.

Below in conjunction with drawings and Examples the utility model is described further:

Fig. 1 is the multi-function water tap section of structure.

Among the figure: 1. valve plug 2. valve rods 3. valve bodies 4. Sealed casing pipes 5. eccentric crankshafts 6. are worn pin 7a, 7b. eccentric opening 8. handles 9. water outlets 10. water intakes

Embodiment: earlier with the pig iron, non-ferrous metal or valve body 3 of plastics casting, the water outlet 9 of valve body 3 is designed to taper mouth, spool do valve plug 1 with conical surface plug, be positioned at valve inleting water mouth 10 places, with the inner face taper fit of water intake 10.Valve rod 2 passes across valve body 3, its the other end is connected eccentric crankshaft 5 by wearing pin 6 with eccentric opening 7, be connected with handle 8 on the eccentric crankshaft 5, valve rod 2 seals by Sealed casing pipe 4 near eccentric crankshaft 5 one ends, Sealed casing pipe 4 one ends tightly are placed on the valve rod 2, the other end riveting knot adopts the rubber with stretchability to make on valve body 3.Eccentric opening on the eccentric crankshaft is designed to two, two throw of eccentric difference, when valve rod 2 connects eccentric crankshaft 5 by the little eccentric opening 7a of throw of eccentric, water tap possesses the water-stopping self-closing function, when connecting eccentric crankshaft 5 by the big eccentric opening 7b of throw of eccentric, but water tap possesses anhydrous all automatic closing functions is arranged.

On the utility model basis, also can realize full automatic self-open and self-close, only need this water tap upset, promptly water outlet is upwards hung a ball float again on handle, has just become delay switch in the float valve, be applicable to wet pit or the equipment that regularly discharges water in.
