Description
Technical field
The present invention relates to a kind of limit of hydraulically operated equipment and fine tuning structures.
Background technique
Hydraulically operated equipment as one of three big main driving device types, have stable drive is reliable, have buffering without hit, it is anti-
The advantages that deviation capability is good, degree of regulation is high, fast response time.But because its is bulky, involve great expense, installing engineering amount is more
The disadvantages of, so being mainly used in part at present has the industries such as power plant, the petrochemical industry of the particular/special requirements such as quick closing valve or Slow Close.
Hydraulically operated equipment generally all has a problem that at present: not having mechanical limit structure.Due to hydraulically operated equipment thrust or
Torque is all larger, will lead to valve in this way and occurs closing excessive phenomenon, so that it is difficult or leakage to open valve appearance
Problem, so one hydraulically operated equipment with mechanical limit structure of design is at a urgent problem to be solved.
Summary of the invention
To overcome above-mentioned prior art problem, the present invention provides a kind of limit of hydraulically operated equipment and fine tuning structures.
The technical scheme is that limit and the fine tuning structure of a kind of hydraulically operated equipment, including hydraulic cylinder, hydraulic stem, tooth
Item, gear-box, the gear-box are equipped with adjusting hole, and the circular shaft of the rack gear end is equipped with screw thread, has spiral shell on the screw thread
Mother I and nut II, the nut I and gear housing abut, and the nut II is abutted with nut I, the nut I and nut II
Circumferential end surfaces are equipped with counterbore, are inserted with adjustment bar I on the nut I in counterbore, are inserted with adjustment bar in counterbore on the nut II
II, the adjustment bar I and adjustment bar II run through adjusting hole.
Further, the outer diameter of the nut I and the width of circumferential end surfaces are bigger than nut II.
Further, the counterbore more than one in the circumferential end surfaces of the nut I and nut II.
The invention has the advantages that nut I and gear housing abut, the limit function of hydraulically operated equipment, nut are realized
II abuts with nut I, realizes the locking functions of nut I；It adjusts bar I and adjustment bar II distinguishes turn nut I and nut II, thus
Realize the regulatory function of limit.

Specific embodiment
As shown in Fig. 2, limit and the fine tuning structure of a kind of hydraulically operated equipment, including hydraulic cylinder, hydraulic stem, rack gear, gear-box,
The gear-box is equipped with adjusting hole, and the circular shaft of the rack gear end is equipped with screw thread, has nut I and nut on the screw thread
II, the nut I and gear housing abut, and realize the limit function of hydraulically operated equipment, and the nut II is abutted with nut I, real
The circumferential end surfaces of the locking functions of existing nut I, the nut I and nut II are equipped with counterbore, are inserted in counterbore on the nut I
Bar I is adjusted, is inserted with adjustment bar II on the nut II in counterbore, the adjustment bar I and adjustment bar II run through adjusting hole, pass through tune
Whole bar I and adjustment bar II distinguish turn nut I and nut II, to realize the regulatory function of limit.The outer diameter of the nut I and
The width of circumferential end surfaces is bigger than nut II.Counterbore more than one in the circumferential end surfaces of the nut I and nut II.
Technical solution of the present invention abuts nut I and gear housing, realizes the limit function of hydraulically operated equipment, nut II with
Nut I abuts, and realizes the locking functions of nut I；It adjusts bar I and adjustment bar II distinguishes turn nut I and nut II, to realize
The regulatory function of limit.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art
Member can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as at this
All by the protection of Patent Law in the scope of the claims of invention.
