Description
Technical field
The utility model relates to a kind of float-ball type leverage of fluid level control valve.
Background technique
The control liquid level adopts float valve mostly in industrial production, as the liquid level control of wet pit.Traditional float valve adopts the tin bronze manufacturing, and its principle is that the buoyancy of ball float is forced to block water outlet by the lever reinforcing.It is not enough more that this fluid level control valve exists, and belonged to obsolete product.In recent years, developed the fluid level control valve that utilizes the hydraulic self-locking sealing, its float-ball type leverage only needs can to change the valve pocket internal pressure with minimum control force to be changed, thus the opening and closing of control valve; The lever arm length of float-ball type leverage and the diameter of ball float need not make corresponding changes with the size of diameter of outflow tube.Though the adaptability of this float-ball type leverage is very strong, but still find to have deficiency in practicality: one to be provided in a side of the number of teeth of the angle adjustment gear on the lever head less and profile of tooth is rectangular, be provided with ring gear with the angle adjustment gear matched at an end of lever arm, its number of teeth and profile of tooth identical with the angle adjustment gear also should be rectangle mutually, need during the angle of inclination of adjustment (adjusting) lever arm gear and gear ring are aimed at and can be finished, thereby regulate inconvenience, the shelves number that the lever arm angle of inclination is regulated is less; The 2nd, lever arm is realized with cooperating by the bearing pin insertion with clamp wedging mode of lever head, the situation that bearing pin fractures or clamp comes off often occurs, thereby reliability is relatively poor; The 3rd, lever arm one end is threaded with being connected to of ball float, occurs silk thread mouth easily and damages, and does not establish Sealing in addition, thereby water takes place enters situation in the ball float, makes the liquid level Control Failure.Solve the problem that occurs in the practice, must improve existing float-ball type leverage.
Summary of the invention
The purpose of this utility model provides a kind of float-ball type leverage of fluid level control valve, and the shelves number that its lever arm angle of inclination is regulated is many, and adaptability is strong, reliable operation, long service life.
The float-ball type leverage of a kind of fluid level control valve described in the utility model comprises lever arm, and an end of lever arm is connected with lever head, and the other end of lever arm is connected with ball float; Lever head is an overall structure, and the inboard that is provided with symmetrical locating stud, bottom in the outside of the bottom of lever head is provided with symmetrical control pin; Be provided with the angle adjustment gear on the top of lever head, the center of angle adjustment gear is provided with an attachment hole; It is characterized in that the number of teeth of angle adjustment gear is at least 12, profile of tooth is triangular in shape; Be provided with screw thread in the attachment hole of angle adjustment Gear center; The end that lever arm is connected with lever head is provided with the ring gear with angle adjustment gear corresponding matching, and the center of ring gear is provided with a through hole; The attachment hole that screw passes the angle adjustment Gear center on the through hole at ring gear center and lever head top is connected, and ring gear is enclosed within outside the angle adjustment gear, and the internal tooth of ring gear and angle adjustment gear external tooth mesh fully.Increase the number of teeth of angle adjustment gear, promptly increased the gear of angle adjustment, thereby its adaptability is strengthened.Change the angle adjustment tooth-formation of gear, make adjusting angle simple to operate.Lever head with use screw being connected of lever arm instead and connect, frangibility is not installed and is adjusted all very easy.
The float-ball type leverage of described a kind of fluid level control valve, the other end of its lever arm and ball float are provided with seal ring for being threaded in the joint.The effect that seal ring is set is to avoid water or other liquid to enter in the ball float, to guarantee the reliability of liquid level control.In ball float and sleeve pipe that the lever arm the other end is connected, be provided with a riffled tube.The material of riffled tube is identical with the material of lever arm, inlays in the sleeve pipe of ball float, can reduce the situation that the connecting filament mouth damages.
The utility model is compared with prior art, has the following advantages: no matter fluid level control valve from which direction is installed, and can adjust water level easily; The shelves number that the lever arm angle of inclination is regulated is many, and adaptability is strong; It is easy that adjustment is installed, and is connected firmly good reliability; Not fragile, long service life.
