The invention discloses a water control valve with a flow rate continuous control function. The water level control valve comprises a valve body, a valve core, a valve body cover, a floating ball connecting device and a floating ball, wherein the water body is provided with a water inlet cavity and a water outlet cavity; a water outlet hole is formed in the side wall of the water outlet cavity; a returning spring is arranged in one end, connected with the water inlet cavity, of the water outlet cavity; the valve core is arranged in the water inlet cavity; a step hole matched with the retuning spring is arranged at the water inlet end of the valve core; a balance hole is formed in a water outlet end surface; the valve body cover is provided with a centre hole and a floating ball rod seat; the floating ball connecting device comprises a valve core mandrill and a floating ball rod; one end of the valve core mandrill passes through the centre hole to contact the valve core; and the other end of the valve core is connected with the floating ball rod. The water level control valve with the flow rate continuous control function has the advantages that: the flow rate at a valve port can change continuously according to the water level in a water pool; the water inlet cavity and the water outlet cavity form a 45-degree structure, so that the dead weight of the floating ball and the floating ball rod overcomes the frictional force of the valve core; therefore, the action of the valve is more flexible and reliable.
Description
Technical field
The present invention relates to a kind of altitude valve with flow continuous control function, belong to the electromechanical equipment field.
Background technique
At present, no matter the altitude valve that provides on market is mechanical type or electronic type, is all the switch control mode basically, and valve is in the "on" and "off" two states, can only control water level " height ", " low " two kinds of situations.And control at some water levels the water-outlet quantity that demanding special occasions needs control valve, adapt to the continuous variation of water level.Therefore, developing the altitude valve with flow continuous control function is an important research topic.
Summary of the invention
The present invention is directed to the accurately problem of control valve water-outlet quantity of current water level control valve, proposed a kind of altitude valve with flow continuous control function.
Altitude valve with flow continuous control function of the present invention, comprise valve body, spool, body cap, ball float connection set, ball float, described valve body is provided with water-inlet cavity, water chamber, it is characterized in that: described water chamber sidewall is provided with osculum, and the inner Returnning spring of installing of an end that is connected with described water-inlet cavity, it is inner that described spool is placed in described water-inlet cavity, and the end of described Returnning spring inserts the feed-water end of described spool; Described spool feed-water end is provided with the step hole that coordinates with described Returnning spring, and the water outlet end face is provided with equalizing orifice; Described body cap is provided with center hole and ball float pole socket; Described ball float connection set comprises spool push rod, ball lever, described spool push rod one end passes described center hole and contacts with described spool, the other end is connected with described ball lever by bearing pin, and described ball lever one end connects hinge joint on described ball float pole socket, and the other end connects ball float.
Described water-inlet cavity and described water chamber axis are and are miter angle.
Be circumferentially with trapezoidal water-flowing trough along described osculum.
Described spool is circumferentially with the bar shaped effluent trough, and place, effluent trough both sides is provided with seal groove.
Described ball lever is provided with bar hole, and described bearing pin is loaded in described bar hole.
Described spool push rod and described center hole contact position are circumferentially offered enclosed slot, and seal ring is housed.
Described body cap is circumferentially with seal groove with the end face that described valve body contacts.
During use, the valve inleting water mouth is connected with supply channel, osculum is at the water chamber side-lower; Spool in water chamber along wall sliding; Spool causes space between spool and body cap by equalizing orifice with inlet water, makes the spool both ends of the surface be subjected to hydraulic balance, avoids spool to be subjected to the additional water pressure-acting; Water in the pond is in low water level, ball float also is in low level, under the effect of the weight of ball float and ball lever, the spool push rod moves in valve body, spool is depressed into valve body water chamber lowermost end, spool sidewall upper water-out groove is alignd with valve body upper water-out hole, and the osculum orifice size is maximum, and water output is also maximum; After water level in water pool rose, ball float rose, and drove ball lever and upwards swung, and spool moves upward under action of reset spring, staggered in effluent trough and osculum position, and orifice size reduces, and water supply flow reduces; When ball float rose to the extreme higher position, spool effluent trough and valve body osculum staggered fully, valve closing.Water level in water pool decline process and aforementioned process are just the opposite.
Beneficial effect of the present invention:
(1) the present invention adopts the through-flow mode of spool axle center hole to control water (flow) direction, and the spool both ends of the surface are communicated with, and has greatly reduced the unstability of the valve core movement that instantaneous hydraulic dynamics and steady-state fluid force cause, valve is obtained better dynamically and static stability.
(2) the present invention's mode of adopting the spool sidewall to leave tank coordinates with the valve body osculum and carries out orifice size and control, and has improved the controllability of valve port, and the valve port flow can be changed continuously according to water level in water pool.
(3) the present invention adopts water-inlet cavity to become the valve body structure of 45 degree with water chamber, makes the ball lever hunting range between 45 degree are spent to 90, and the deadweight of ball float and ball lever can effectively overcome the effect of spool frictional force, makes valve event sensitiveer, reliable.
