Abstract
The utility model discloses a ball cock which aims at providing a ball cock being able to prevent the water flow from the rear of the valve body, which has simple structure. The ball cock of the utility model includes a water source connecting end in the front end of the valve body; a pair of mounting journal stirrups are arranged in one side of the rear of the valve body, in the side wall between which a mounting slot is arranged; a lever is arranged between the journal stirrups through a pin roll; the sealing end of the lever is arranged inside the valve body which can plug up the water source connecting end while moving and the other end of the lever is connected with the ball; a hole is arranged in the rear of the valve body; the middle of the valve body heaves to the cavity of the valve body which can plug up the upper end of the hole in the process of movement; the mounting slot of the side wall of the valve body extends to be connected with the hole in the rear of the end of the valve body and the end of lever which is connected with the ball extends out from the hole; so when in use, the stream can not be sprinkled form the upper end of the rear hole of the valve body even if the pressure of the water source increases, thus avoiding the unsafe factors caused by the hot water falling in the balls and splashing to everywhere.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of float valve that can control water level.
Background technique
The flushing cistern float valve that generally uses on the market is the flowing water aperture that comes shutoff water source interface end by the lever drives piston of band ball float now, reach the purpose of control water level, owing to use piston, after long-time use, the impurity in the water forms incrustation scale easily and makes piston dirt knot; The floating ball water valve that also has some other form, mostly complex structure.Applicant has been submitted the utility application that name is called " float valve " on February 25th, 2003 to Patent Office of the People's Republic of China, provide a kind of simple in structure, reliable operation, be not easy by the float valve of incrustation scale dirt knot, but find in using: when the water pressure that enters from the water source interface end increases, there be the situation of current from upper end, the hole ejection of valve body afterbody, the water of ejection drops on the ball float and splashes everywhere, when being hot water in the water tank, just brought hidden danger; In addition, the valve body after the casting also needs further to process the hole of afterbody, and production process is complicated.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provide a kind of prevent current from the hole ejection of valve body afterbody, make simple float valve.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of float valve, the water source interface end that comprises the valve body front end, there is a pair of installation journal stirrup the side of valve rear end, the body wall of installing between the journal stirrup has mounting groove, lever is installed between the journal stirrup by bearing pin, the sealed end of lever is positioned at valve body, can block the water source interface end during motion, another termination ball float of lever, the valve body afterbody is porose, the cavity projection of the middle part of above-mentioned lever in valve body, the upper end in above-mentioned hole can be blocked in movement process, the mounting groove of above-mentioned body wall extends to the hole perforation with the valve body afterbody, and the end that lever connects ball float stretches out in the hole.
The beneficial effects of the utility model are: because the cavity projection of middle part in valve body of lever, in movement process, the hole of valve body afterbody can be blocked, when the water pressure that enters from the water source interface end increased, current can not avoided hidden danger from the hole ejection of valve body afterbody; The Kong Bingyu hole that the mounting groove of body wall extends to the valve body afterbody connects, and makes that whole valve body can disposable casting, needn't process the hole of afterbody more in addition, makes simple.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a stereogram of the present utility model.
Embodiment
With reference to Fig. 1, Fig. 2, float valve comprises the water source interface end 1 of valve body 4 front ends, macropore 2 is arranged in the water source interface end 1, and the lower end of macropore 2 is apertures 3, and there is a pair of installation journal stirrup 9 side of valve body 4 rear ends, install between the journal stirrup 9 mounting groove 15 is arranged, the effect of mounting groove 15 is to be used to install lever 13, and makes its space that rotation is arranged and double as flow channel, and lever 13 is being installed between the journal stirrup 9 by bearing pin 8, one end 7 is positioned at valve body 4, and the other end 10 connects ball float 12 by connecting rod 11; When water level raise, ball float 12 drove lever 13 and rotates around bearing pin 8, and sealing rubber pad 6 closed pores 3 on the end face 7 can not flow out water.Valve body 1 afterbody porose 14, hole 14 is to be used to process aperture 3 and double as flow channel, cavity 5 projectioies of lever 13 middle parts in valve body, when water level was low, ball float 12 drove levers 13 around bearing pin 8 counter-rotation, until the upper end in the hole 14 of valve body afterbody is blocked, like this, when even hydraulic pressure increases, current can not avoid hot water to drop on the hidden danger of splashing and bringing on the ball float everywhere from the upper end ejection in the hole of valve body afterbody yet.
The hole 14 that the mounting groove 15 of body wall extends to the valve body afterbody connects, and whole valve body just can disposable casting like this, and the hole that needn't process afterbody more in addition has enough spaces and is used to process aperture 3, makes simpler.
