Abstract
The utility model discloses a two-position control double-float ball valve for the control of high and low liquid levels, which comprises a valve body, a valve core, a crank, a connecting rod, two ball floats, a rotating shaft, a gag lever post and a stop pin and solves the problem of unable realization of the control of two liquid levels in the prior art. The utility model is characterized in that the control of high and low liquid levels is realized, and the utility model can be used for fireproofing and explosion-proof occasions in chemical plants or places which need two-position control of liquid level of the liquid storage tanks. The utility model is especially for the control of water inflow for solar water heaters, discontinuous steam water heaters, and elevated water tanks of residential houses.
Description
The utility model is a kind of automaton.Particularly without the automaton of high and low two controls of the liquid level of power supply or other power-assisted.
Liquid level control principle in the existing liquid reserve tank without power supply or other power-assisted the time, can only adopt common ball-cock assembly.This common ball-cock assembly performance is opening or closing by the liquid level by-pass valve control of setting.Be liquid level when being reduced to the liquid level of setting, ball float makes valve opening along with liquid level descends, and liquid storage covers container, as liquid reserve tank.When liquid level rose to the setting liquid level, ball float made valve closing along with liquid level rises, and stops feed liquor in container, as liquid reserve tank.When liquid level descended once more, valve was opened feed liquor once more, and liquid level rises to when setting liquid level, and valve closing so returns again, made the interior liquid level of liquid reserve tank remain on certain setting height.At present, the control of the water levels such as liquid storage container of Urban House roof water tank, chemical plant production usefulness all utilizes above-mentioned principle, and adopts common ball-cock assembly class device.This device can only make and keep a fixing liquid level in the liquid reserve tank.But its deficiency is to realize high and low two controls.
The purpose of this utility model is to provide a kind of and can works as when liquid level drops to the low level of regulation in the liquid storage container, open the valve feed liquor, when liquid level in the liquid storage container was raised to the high liquid level of regulation, valve closing stopped the automaton of feed liquor, i.e. two two ball-cock assemblys of control.
The utility model is realized by following measures: control liquid level height, the low two ball-cock assemblys of two controls, it comprises valve body, spool, crank, connecting link (4), upper ball float, rotation axis, it is characterized in that it also comprises gag lever post, stop pin, connecting link (9), the next ball float, be equipped with inlet on the valve body, liquid outlet, guide cylinder, support the support of crank, guide cylinder and support and valve body are an integral body, spool is put in the valve body chamber, can move vertically, on spool, be equipped with pilot hole, the actuating hole, stop pin and guide cylinder flexibly connect by gag lever post, connecting link connects stop pin with the next ball float, rotation axis places on the support, so that crank is connected with support, one end of crank places in the actuating hole on the spool, the other end of crank is connected with upper ball float by connecting link, when vessel level can not be floated the next ball float, the gravitate stop pin breaks away from the pilot hole certain distance, upper ball float gravitate makes rotate moving axis motion of crank, end by crank cooperates with the actuating hole moves spool vertically, inlet is opened, and liquid enters container from inlet; Liquid level constantly rises in container, the liquid body buoyancy, and upper float ball constantly rises, and when the liquid level of liquid rises to when stop pin is cooperated with pilot hole, inlet is blocked by the other end of spool, and liquid no longer enters in the container.Stop pin is subjected to the buoyancy of the next ball float simultaneously, inserts in the pilot hole.When liquid level descended, liquid still can not enter container, dropped to below the next ball float until liquid level, and the stop pin gravitate breaks away from pilot hole, and the upper ball float of gravitate descends simultaneously, by crank spool is moved, and causes valve open.
The utility model compared with prior art has following beneficial effect: open inlet when hanging down liquid level owing to the utlity model has, close inlet during high liquid level, realize the characteristics of dibit control function, this utility model technical solution, satisfied chemical industry factory and more be applicable to solar water heater, discontinuous vapour water heater and residential houses elevated tank control water inlet in the requirement of preventing fires, explosion-proof two modes of occasion needs are controlled the liquid storage container liquid level.
Description of drawings
Accompanying drawing is the structural representation of two two ball-cock assemblys of control.
Now the utility model will be further described in conjunction with the accompanying drawings: a kind ofly be used to control the liquid level height, the low two ball-cock assemblys of two controls, it comprises valve body (1), spool (2), crank (3), connecting link (4), upper ball float (5), rotation axis (6), it is characterized in that it also comprises gag lever post (7), stop pin (8), connecting link (9), the next ball float (10), be equipped with inlet on the valve body, liquid outlet, guide cylinder (11), support the support (12) of crank, guide cylinder (11) and support (12) are an integral body with valve body (1), spool (2) places in valve body (1) chamber, can come and go vertically and move, on spool (2), be equipped with pilot hole (13), actuating hole (14), stop pin (8) flexibly connects by gag lever post (7) with guide cylinder (11), connecting rod (9) connects stop pin (8) with the next ball float (10), rotation axis (6) places on the support (12), so that crank (3) is connected with support (12), one end of crank (3) places in the actuating hole (14) on the spool (2), and the other end of crank (3) is connected with upper ball float (5) by connecting link (4).Above-mentioned each element is made according to the different available metals of use occasion, also available plastic production, and particularly copper is better.One end of valve body (1) is connected with an end of feed tube and guarantees that liquid enters container, one end of valve body is an inlet, in the middle of valve body (1), be provided with liquid outlet, spool (2) places in valve body (1) chamber, guide cylinder (11) is connected as a single entity with valve body (1), place between the support (12) of liquid outlet and support crank, support the support (12) of crank to be connected as a single entity with valve body (1), place the other end of valve body (1), stop pin (8) is contained in the guide cylinder (11), and on can be in guide cylinder (11), following motion, and limit the stroke that stop pin (8) moves up and down with gag lever post (7), do not make simultaneously its rotation, connect connecting link (9) and the next ball float (10) successively in stop pin (8) bottom, the next ball float (10) is finished the upwards function of locking spool (2) by buoyancy of liquid, leans on the gravity of the next ball float (10) self to move downward, to the unlocking function of spool (2).Supporting by rotation axis (6) crank (3) to be housed on the support (12) of crank, crank (3) at an angle of 90, crank (3) moving axis (6) motion that rotates.One end of crank (3) is inserted in spool (2) the actuating hole (14) vertically upward, and the other end of crank (3) keeps horizontality, is connected with upper ball float (5) by connecting link (4).When ball float moved up and down because of the liquid level lifting, then crank (3) was that rotate at the center with the rotation axis on the support (6), and then the vertical end of crank (3) promotes spool (2) motion.For satisfying the not different supporting needs of feed tube diameter of co-content liquid reserve tank, press regular size, can be made into latus rectum and be 15,20,25,32,40,65,80, the 100m/m plurality of specifications.For satisfying the different requirements of liquid level difference, can realize by the length that changes connecting link (4).
