Abstract
The utility model discloses a floating ball liquid level control valve which comprises a floating ball 3, a valve body 2 and a valve core 1 which are assembled in a combinatorial way. The utility model is characterized in that the inner part of the valve body is provided with an annular flow split passage 4 which is provided with two to six liquid averaging holes 5 which are matched with a hollow valve rod of the valve core 1. The utility model has the advantages that under the actions of the flow split passage and the liquid averaging holes, radial force borne at the position on the valve rod is uniform and equal, and is in reverse direction and mutual counteraction. Consequently, the opening and the closing of the valve are flexible and reliable, and the liquid level control is accurate.
Description
The utility model relates to valve, is the Floating Ball Liquid Level Control valve of liquid level in the controlling liquid container furtherly.
Floating Ball Liquid Level Control valve in the prior art, have only an inlet opening in the position of liquid entering hole and spool, the suffered radial force of spool concentrates on the valve rod sidewall of a side, has increased the frictional force between spool and the valve body, when pressure is excessive, will make spool stuck, and uncontrollable liquid level.
In order to overcome the deficiency that exists in the prior art, the purpose of this utility model has been proposed, the purpose of this utility model provides a kind of novel Floating Ball Liquid Level Control valve, to overcome the deficiency that prior art exists.
The purpose of this utility model is to realize according to following structure, this Floating Ball Liquid Level Control valve, comprise the ball float 3 of combine and assemble in one, valve body 2 and spool 1, it is characterized in that annular runner 4 being arranged, have 2-6 equal liquid hole 5 that cooperates with the hollow valve rod of spool 1 on this runner at valve inner.
The utility model has the advantages that, runner on the valve body and the equal liquid hole that cooperates with valve rod have been increased, the fluid pressure that enters valve body during work is divided into two through runner, and then enter valve rod through two or four or six equal portions, the suffered radial force in this position evenly waits big and reverse on the valve rod, cancel out each other, so the open and close flexibility and reliability of valve.Can satisfy the liquid level control of big pressurized container.
The following drawings explanation, accompanying drawing 1 is the structure sectional view of this control valve, and accompanying drawing 2 is A-A sectional drawings of accompanying drawing 1, and the meaning of each sequence number in the accompanying drawings is: 1, spool 2, valve body, 3, ball float, 4, runner, 5, equal liquid hole.
Describe structure of the present utility model and use in detail below in conjunction with the embodiment in the accompanying drawing, with reference to accompanying drawing, the ball float 3 that is assembled together, valve body 2 and spool 1, constituted Floating Ball Liquid Level Control valve of the present utility model, it is characterized in that annular runner 4, the fluid pressure that enters valve body is divided into two through runner at valve inner.Have 2-6 equal liquid hole 5 on the runner, cooperate with equal liquid hole 5 on the hollow valve rod of spool 1.Liquid after the shunting through equal liquid hole 5, enters into hollow interior inflow of valve rod, and the outer liquid level of ball float is constantly increased, and drives ball float simultaneously and rises, and the liquid entering hole at the runner place on the valve body is closed gradually, keeps liquid level equilibrium.When the liquid level in it descended, ball float moved down, and the liquid entering hole at runner place is opened gradually, and liquid level rises to once more gradually again and closes.So form reciprocation cycle, reach the purpose of control liquid level.Because equal liquid hole is evenly to arrange on circumference, so the suffered radial force in this sectional position evenly waits greatly and reverse on the valve rod, cancels out each other, so the open and close flexibility and reliability of valve.Avoided the stuck fault of valve the prior art from structure fully.
