Abstract

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; areturning 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 retuningspring 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 [0001] The invention relates to a water level control valve with a continuous flow control function, which belongs to the field of electromechanical equipment. Background technique [0002] At present, whether the water level control valves provided on the market are mechanical or electronic, they are basically switch control methods. The valve is in two states of "on" and "off", and can only control the water level in two states of "high" and "low". situation. In some special occasions with high water level control requirements, it is necessary to control the water output of the valve to adapt to the continuous change of water level. Therefore, it is an important research topic to develop a water level control valve with the function of continuous flow control. Contents of the invention [0003] Aiming at the problem that the current water level control valve cannot accurately control the water output of the valve, the invention proposes a water level co...
