Description
Technical field
The utility model relates to valve rod technical field more particularly to a kind of valve rods for throttle valve.
Background technique
Throttle valve is by changing throttling section or chock length to control the valve of fluid flow.By throttle valve and unidirectionally
Valve parallel connection is then combined into one-way throttle valve.Throttle valve and one-way throttle valve are easy flow control valves, in quantitative pump hydraulic pressure
In system, throttle valve and overflow valve cooperation constitute three kinds of Metering Flow Control Circuits, i.e. in-line Metering Flow Control Circuits, oil return line
Metering Flow Control Circuits and bypass throttling speed governing system.And valve rod is valve important component, for being driven, Shang Jie executing agency or
Handle, band movable valve plug is mobile directly below or rotates, to realize valve switch or adjustment effect.Valve rod is in valve opening and closing process
In not still movement parts, stressed member, and be sealing element.Meanwhile its impact and corrosion by medium, also rub with filler generation
It wipes.Therefore when selecting stem material, it is necessary to assure it have at an established temperature enough intensity, good impact flexibility,
Resistance to marring, corrosion resistance.Valve rod is vulnerable part, should also be noted that the machining property and heat-treatability of material when selecting
Energy.
Regardless of the more valve rods high, how strong impact flexibility is of intensity all may due to the union end long-time stress of its bottom
It will appear the phenomenon that fractureing, the bottom of valve rod can remain in inconvenient taking-up in valve body, bring not to the maintenance of throttle valve after fractureing
Just, we design a kind of valve rod for throttle valve thus, to solve the above problems.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and the one kind proposed is used for throttle valve
Valve rod.
To achieve the goals above, the utility model adopts the technical scheme that
A kind of valve rod for throttle valve, including valve stem body and handwheel are provided with spiral shell on the outer wall of the valve stem body
Line, and the bottom of valve stem body is fixedly installed union end, and cavity is provided in the union end, the cavity is cylindrical shape
Structure, and center-pole is fixedly connected between the top and top of cavity vertically, the center-pole is cylindrical shape hollow structure
And the center of the inner top of center-pole and interior bottom is fixedly welded with fixed ring, is provided with drawing between two fixed rings
Rope, the fixed horizontal connection in the one end of the valve stem body far from the union end have lower fixed disk, and the bottom of the handwheel is vertical
It is fixedly connected with connecting rod, the bottom of the connecting rod is fixedly connected with fixed disk, and fixed disk and lower fixed disk are equal
Setting in the form of annular discs, and it is provided through bolt vertically in upper fixed disk.
Preferably, the bottom centre of fixed disk is provided with fixed block, and the top center of the lower fixed disk opens up
There is fixing groove, the fixed block and fixing groove are in cube-shaped and are mutually adapted.
Preferably, the both ends of the drawstring are bolted to respectively in two fixed rings, and drawstring is wirerope.
Preferably, there are two the bolt is arranged altogether, and vertically through having fixed circular hole and the bolt in upper fixed disk
It is adapted.
Preferably, the top fixation of the lower fixed disk offers screw hole, and screw hole is adapted with the bolt.
Compared with prior art, the utility model has the beneficial effects that
1, by the design of union end, cavity, center-pole, fixed ring and drawstring, fracture can be used in the bottom of valve rod
When, the bottom end of fracture is taken out from throttling valve body, it is more convenient to use convenient for the replacement of valve rod.
It 2, can be quickly by consolidating in upper fixed disk by the design of upper fixed disk, lower fixed disk, fixed block and fixing groove
Determine circular hole to be connected to the screw hole on lower fixed disk, so as to further fixing for bolt, facilitates the fixation between handwheel and valve rod
Installation.The utility model is simple in sturcture, ingenious in design, solves previous throttle valve stem bottom break and is not easily taken out, replaces not
Just the problem of, practical, it is easy to spread.
