Abstract
The utility model discloses an oil-compensating valve which belongs to the technical field of a hydraulic diaphragm metering pump component. The oil-compensating valve comprises a valve seat and a pressing valve nut correspondingly matched with the valve seat, wherein a radial through hole is arranged on the valve seat, connecting rod balls are strung in the valve seat in a matching mode, ball bodies of the connecting rod balls and holes of the valve seat form a pair of sealing pairs, and the lower part of a rod body of the connecting rod balls is provided with a spring seat and a spring correspondingly matched with the spring seat. The oil-compensating valve has the advantages of simple structure and reasonable design, and because the spring seat and the spring correspondingly matched with the spring seat, which are arranged at the lower part of the rod body of the connecting rod balls, are movably matched with a spacing valve, the utility model realize automatic oil compensation; the ball bodies of the connecting rod balls and the holes of the valve seat form the pair of sealing pairs so that the utility model ensures the unidirectivity of oil compensation, and meanwhile, the performance of the oil-compensating valve is enhanced.
Description
Technical field
The utility model relates to the Hydraulic Diaphragm Metering Pump parts, is specifically related to Fill valve.
Background technique
In the Hydraulic Diaphragm Metering Pump of present numerous domestic, Fill valve is to guarantee one of requisite constituent elements of Hydraulic Diaphragm Metering Pump proper functioning.In the Hydraulic Diaphragm Metering Pump working procedure, the fluid in the hydraulic pressure cavity reduces owing to leaking, and influences the proper functioning of Hydraulic Diaphragm Metering Pump.Fill valve has compensation hydraulic pressure cavity internal cause and leaks and the effect of minimizing hydraulic-oil quantity, makes that the volume of the interior hydraulic oil of hydraulic pressure cavity remains unchanged between plunger and the barrier film, guarantees the proper functioning of metering pump.Traditional Fill valve, complex structure, it is reasonable inadequately to design.
The model utility content
For overcoming problems of the prior art, the utility model aims to provide a kind of structure and simplifies, and is reasonable in design, and the Fill valve of repairing automatically.
Described Fill valve, comprise the pressure valve nut of valve seat and corresponding cooperation, radial direction through hole is set on the valve seat, cooperate in the valve seat to be equipped with the connecting rod ball, the spheroid of connecting rod ball and the aperture of valve seat constitute a pair of sealing pair, and the body of rod bottom of connecting rod ball is provided with the spring of spring seat and corresponding cooperation.
Described Fill valve, the corresponding filter screen that cooperates of its valve seat arranged outside with radial direction through hole.
Described Fill valve, it is pressed the bottom of valve nut to cooperate and is provided with sealing nut, presses between valve nut and the sealing nut and is provided with sealing gasket.
Described Fill valve, the bottom of its spring seat cooperate with the body of rod of connecting rod ball and are provided with locking nut.
Described Fill valve, its valve seat upper end is provided with seal ring, presses the upper outside of valve nut to be provided with lower seal.
Described Fill valve, structure is simplified, and is reasonable in design, utilizes the body of rod bottom of connecting rod ball to be provided with the spring of spring seat and corresponding cooperation, realizes automatic repairing; And the aperture of the spheroid of connecting rod ball and valve seat constitutes a pair of sealing pair, has then guaranteed the one-way of repairing; Improved the performance of Fill valve simultaneously.
