The utility model discloses remote transmission can be realized, low -angle transmission requirement is satisfied, in addition, the production of still being convenient for, installation.
Description
Technical field
This utility model belongs to valve technology field, more particularly to a kind of universal joint valve rod elongate structure.
Background technology
As buried valve, because valve is installed on the ground end apart from ground certain altitude, operated according to valve handle
The height at center and valve pipe center, the valve rod of valve must carry out lengthening extension, so as to ensureing grasping for actuator
The property made.
In addition some Lengthening mechanisms in prior art have asking for complex structure, production and installation all inconveniences
Topic.
Utility model content
In order to overcome the shortcomings of background technology, this utility model provides a kind of universal joint valve rod elongate structure, realizes remote
Distance transmission, is easy to produce, installs, while can meet low-angle transmission requiring.
The technical scheme that this utility model is adopted：A kind of universal joint valve rod elongate structure, including extension bar, lengthen
Pipe, adapter sleeve, pin；The extension pipe two ends connect respectively the extension bar and adapter sleeve, and the extension bar is provided with entering department one,
The connection is arranged with entering department two, and the extension pipe two ends connect respectively the entering department one and entering department by the pin
Two, pin described in two ends is in 90 degree of interlaced arrangements, and between the extension bar, adapter sleeve and the extension pipe gap is provided with.
The gap includes axial gap and radial clearance, the radial clearance be located at the entering department one and extension pipe it
Between and entering department two and extension pipe between in the radial direction, the extension bar and adapter sleeve are designed with step end face, described
Axial gap is located on the axial direction between the step end face and extension pipe.
The beneficial effects of the utility model are：Long-distance transmission is realized by the socket of multiple parts, and using staggeredly peace
The mode of load pin axle, can eliminate the upper and lower connection end processing of valve rod elongate structure, install the mistake not caused in same axis
Difference, makes processing and installs more effective percentage, and precision is more accurate, while free gap is left in each junction, can meet little
Angle drive is required.

Specific embodiment
This utility model embodiment is described further below in conjunction with the accompanying drawings：
As illustrated, a kind of universal joint valve rod elongate structure, including extension bar 1, extension pipe 2, adapter sleeve 3, pin 4；Institute
State the two ends of extension pipe 2 and connect the extension bar 1 and adapter sleeve 3 respectively, the extension bar 1 is provided with entering department 1, the connection
Set 3 is provided with entering department 2 31, and the two ends of the extension pipe 2 connect respectively the entering department 1 and entering department two by the pin 4
31, pin 4 described in two ends is in 90 degree of interlaced arrangements, and gap 5 is provided between the extension bar 1, adapter sleeve 3 and the extension pipe 2.It is logical
Extension bar 1 is crossed, long-distance transmission is realized in the connection of extension pipe 2 and adapter sleeve 3, and the pin 4 forms cross axle structure, same to time control
The free gap of each junction is made, low-angle transmission can be met and required, for needing low-angle to change transmission axis direction
Occasion, eliminates the upper and lower connection end processing of valve rod elongate structure, installs the error not caused in same axis, makes processing and installation
More effective percentage, precision is more accurate.
The gap 5 includes axial gap 51 and radial clearance 52, and the radial clearance 52 is located at the entering department 1
And extension pipe 2 between and between entering department 2 31 and extension pipe 2 in the radial direction, the extension bar 1 and adapter sleeve 3 all set
There is step end face 6, the axial gap 51 is located on the axial direction between the step end face 6 and extension pipe 2.Ensure valve rod
Ensuring smooth transmission, will not produce bite.
The gap 5 is designed according to actual height and the transmission axis deflection angle of lengthening of valve.
Driving means are connected by extension bar with valve rod elongate structure, and adapter sleeve is connected with valve external part valve rod, are lengthened
The length of pipe 2 is designed according to the buried depth of valve.Driving means action, the elongate structure rotation of band ovable valve stem, by moment of torsion simultaneously
Valve rod is reached, valve switch action is driven.
Embodiment is not construed as the restriction to utility model, but any based on spiritual improvements introduced of the present utility model,
All should be within protection domain of the present utility model.
