Abstract
The utility model discloses an automatic closing water tap when water supply is cut off, which is mainly composed of a valve body, a valve core, a handle, etc., wherein, the valve body is divided into a water inlet cavity and a water outlet cavity; a throttle orifice is arranged between the water inlet cavity and the water outlet cavity; the water inlet cavity is provided with a spherical surface-shaped valve core and a sealing and matching valve core sleeve; the spherical surface-shaped valve core is connected with the sealing and matching valve core sleeve by a mandrel; the water outlet cavity is provided with a disk-shaped eccentric cam; the wheel surface of the eccentric cam is always contacted with the lower end of the mandrel; the handle is a wing shape and is coaxially connected the eccentric cam. The utility model has the advantages of simple and reasonable structure, good sealing property, and simple and feasible processing and assembling, and can avoid a dead point when the handle is rotated to 180 DEG.
Description
The utility model belongs to a kind of poppet valve with crank and cam, promptly cuts off the water and closes water tap automatically.
In recent years, because water resources generally lacks, using water wisely becomes to closing main problem, just China's resident living water mostly changes Timing water supply at present, use traditional water tap like this, sometimes owing to carelessness, when cutting off the water, opening tap forgets again and closes, suddenly behind the water, unmanned in the family, then current are more than, cause flood to take place, also cause bigger waste; In order to address the above problem, a kind of ZL95215013.1 " cut off the water and close water tap automatically " is disclosed in the Chinese patent communique, present technique is because valve core structure is unreasonable.Poor sealing performance has dripping phenomenon, easily rust, mandrel difficulty of processing are big after closing; Eccentric wheel is difficult to assembling with combining of mandrel,, structure is complicated, the cost height; The handle center of gravity is prone to the dead point on axis, the possibility that is difficult to close is automatically arranged.
The purpose of this utility model is in order to overcome existing problem in the prior art, and a kind of more reasonable structure, good airproof performance, the easy water tap of assembling, low cost and other advantages are provided.
This purpose is to realize with following technical proposal: it mainly is made up of valve body 1, spool 2, handle more than 4 parts, wherein valve body 1 comprises water-inlet cavity and water chamber and throttle orifice, spool 2 is in water-inlet cavity, said spool is a spherical surface body, and being provided with the curvecd surface type valve core housing 7 that is sealed and matched mutually with it, they are connected by mandrel 3; Be provided with dish type eccentric cam 6 in the water chamber, it is connected with the following end in contact of mandrel 3; Handle is wing, and with 6 coaxial connections of eccentric cam.
The utility model spool part has been owing to used the highi degree of accuracy curved surface to cooperate, so close good airproof performance, be difficult for dripping, is difficult for getting rusty; Mandrel is simple in structure easily to be made up with eccentric cam, has simplified processing technology, has reduced cost; Handle adopts bent body wing, produces the dead point when avoiding handle to rotate 180 °.
Description of drawings of the present utility model:
Cut-away section plan view when Fig. 1 closes for the utility model.
A was to side view when Fig. 2 closed for the utility model.
Cut-away section plan view when Fig. 3 opens for the utility model.
A was to side view when Fig. 4 opened for the utility model.
1~4 pair of overall structure of the present utility model and working principle thereof are done to describe in detail in conjunction with the accompanying drawings:
Shown in Fig. 1,3, this water tap mainly is made up of valve body, spool and handle three parts, there is throttle orifice at the middle part of valve body 1, valve body 1 is divided into two chambeies up and down, and epicoele is a water-inlet cavity, and it is communicated with intake pipe, has certain hydraulic pressure, cavity of resorption is a water chamber, is communicated with water outlet, and hydraulic pressure is bordering on atmospheric pressure.Sphere shape spool 2 is a driven member, it and mandrel 3 join, valve core housing 7 is put in the epicoele and water-inlet cavity is the interference fit assembling, sphere shape spool and valve core housing are sealed and matched, referring to Fig. 1,3, the valve core housing here also just in time is a sphere shape, but also other curved surface that can cooperate with seal spool such as desirable cone-shaped of valve core housing.Mandrel 3 can be with spool play up and down in valve body, eccentric cam 6 is loaded in the valve body cavity of resorption, and it is connected with end in contact under the mandrel.Handling portion is a driving link, and it is connected with eccentric cam is coaxial, and the joint is provided with seal ring 5, and fixes by nut and valve body.
The working principle of this water tap: shown in Figure 2: clockwise or rotate counterclockwise handle 4, (see figure 3) drives dish type eccentric cam 6 and rotates, force mandrel 3 to move up, spool 2 breaks away from valve core housing 7 as a result, water in the epicoele flows into cavity of resorption through throttle orifice, chew discharge from tap, the size of the water yield is decided by the size of wing handle rotation angle.
When the tap water normal water supply, dish type eccentric cam 6 upwards promotes mandrel 3 and moves, under the effect of hydraulic pressure, mandrel 3 gives dish type eccentric cam 6 bigger rotational resistance, so the wing handle of (see figure 4) can be in arbitrarily the position and can not fall down, like this, the size of water flow can arbitrarily be controlled.The resistance that mandrel 3 affacts on the dish type eccentric cam 6 when tap water cut-off has been cancelled, and handle rotates to position shown in Figure 2 automatically under action of gravity, thereby makes water tap be in closed condition, when supplying water, just flood can not take place next time.
Claims (2)
1, a kind of cutting off the water closed water tap automatically, mainly form by valve body (1), spool (2) and several parts of handle (4), wherein valve body (1) comprises water-inlet cavity and water chamber and throttle orifice, spool (2) is in water-inlet cavity, it is characterized in that described spool is a spherical surface body, and be provided with the curvecd surface type valve core housing (7) that is sealed and matched mutually with it, connect by mandrel (3); Establish a dish type eccentric cam (6) in the water chamber, it is connected with the following end in contact of mandrel (3).
2, according to claim 1 cutting off the water closed water tap automatically, it is characterized in that described handle (4) for wing, it and coaxial connection of dish type eccentric cam (6).
