Description
Technical field
This utility model relates to field of hydraulic equipment, is specifically related to a kind of replenishing valve.
Background technology
Replenishing valve belongs to the one of stop valve, it is mainly used in big flow topping up or the discharge opeing of all kinds of hydraulic test plunger shaft in hydraulic drive, to improve its idle running and opening speed, the at present shortcoming of tradition replenishing valve: inside nominal diameter is mostly within 160mm, for the traffic requirement hydraulic system more than 2500L/min inapplicable.
Utility model content
For drawbacks described above and deficiency present in prior art, this utility model provides a kind of replenishing valve, to solve hydraulic test flow value and fill more than ＞ 2500L/min plunger shaft, the problem of discharge opeing.
This utility model is achieved by the following technical solution: a kind of replenishing valve, it is characterized in that: it includes valve body, spool, back-moving spring, spring base, positioning tube and adpting flange, described positioning tube is fixedly installed on the top of valve body, described spool is inverted Y-shaped structure, spool longitudinal sliding motion is arranged in the inner chamber of valve body and reaches in positioning tube, spool 2 sealing surface uses mid frequency induction hardening Technology for Heating Processing, makes the hardness at seal spool reach HRC58-63, and reliability is high.The oil-in and oil-out communicated with inner chamber it is additionally provided with on valve body.
The control oil pocket communicated it is additionally provided with on the inside of valve body and the outer wall of positioning tube, corresponding to controlling oil pocket, control port it is provided with on valve body, replenishing valve is unidirectional to be flowed freely from oil-in to oil-out, when control port has pressure, opening replenishing valve, make communicating into and out of hydraulic fluid port of replenishing valve, fluid can flow from oil-out to oil-in.
The back-moving spring of spool of can resetting is fixedly installed in positioning tube by spring base.
Adpting flange is detachably arranged in the top of valve body.
This utility model compact conformation, profile installation dimension is little, save installing space, logical oil mass is big, can be arranged in fluid pressure line by high pressure flange superposition, meet hydraulic test flow more than 2500L/min fill, the requirement of discharge opeing, spacer flanger install type of attachment, it is easy to maintenance, alternative imported product.
