Abstract
The invention discloses a hand control adjustable hydraulic valve which comprises a valve body, a valve core and a valve seat, wherein an ejector rod is mounted at the left end of the valve body through an ejector rod nut and sleeved with dust cover; and the valve core is arranged in the inner cavity of the valve body, the left end of the valve core penetrates through the valve seat and forms hard seal with the ejector rod, and the right end of the valve core is sleeved with a spring. The hand control adjustable hydraulic valve is simple in structure, long in service life, convenient to maintain, and capable of achieving fast manual adjustment and improving efficiency.
Description
Technical field:
The present invention relates to the valve field, relate in particular to a kind of manual regulating type hydrovalve.
Background technique:
Hydrovalve is a kind of Automation Elements with the pressure oil operation, and it is subjected to the control of voltage distribution valve pressure oil, and common and electromagnetic distributing valve is used in combination, and can be used for the break-make of distant control water power plant oil, gas, water piping system.Be usually used in clamping, control, the oil circuit such as lubricated, dividing of straight ejector half and type pilot, multiplex type pilot are arranged.Traditional hydrovalve, life and reliability are too low, and complex structure can not be realized fast manual tune, and maintenance efficiency is low, have a strong impact on to combine carrying out smoothly of adopting.We release a kind of manual regulating type hydrovalve through independent research, have well solved the problem that the conventional valve life-span is low, maintenance is complicated, have greatly improved manufacturing efficiency.
Summary of the invention:
Purpose of the present invention just provides a kind of manual regulating type hydrovalve.
The technical solution used in the present invention is:
A kind of manual regulating type hydrovalve, include valve body, spool, valve seat, it is characterized in that: described valve body left end is equipped with push rod by the push rod nut, push rod is sheathed with dirt-proof boot, described spool is located at body cavity, and the spool left end passes valve seat and forms hard sealing with push rod, and described spool right-hand member is sheathed with spring, the spring right-hand member contacts mutually with being located at the bolt of valve body by locking nut, and described valve body upper end also is provided with modulating valve.
Compared with prior art, beneficial effect of the present invention is:
The present invention is simple in structure, and high life is easy to maintenance, can realize fast manual tune, raises the efficiency.
Description of drawings:
Accompanying drawing 1 is structural representation of the present invention.
Embodiment:
A kind of manual regulating type hydrovalve, include valve body 8, spool 5, valve seat 4, described valve body 8 left ends are equipped with push rod 1 by push rod nut 3, push rod 1 is sheathed with dirt-proof boot 2, described spool 5 is located at valve body 8 inner chambers, and spool 5 left ends pass valve seat 4 and form hard sealing with push rod 1, and described spool 5 right-hand members are sheathed with spring 7, spring 7 right-hand members contact mutually with being located at the bolt 11 of valve body 8 by locking nut 10, and described valve body 8 upper ends also are provided with modulating valve 6.
