Abstract
The utility model relates to a lengthening device for operating the opening and the closing of a valve, which belongs to the technical field of a liquid transporting pipeline device. The lengthening device for operating the opening and the closing of a valve comprises a lengthening valve rod, wherein the upper end of the lengthening valve rod is provided with a tenon. The lengthening valve rod is arranged on a bottom plate of a box cover by a bearing, and the lower end of the bottom plate of the box cover is fixedly connected with an upper lengthening pipe which is sheathed and fixed on a lower lengthening pipe. The bottom end of the lower lengthening pipe is matched with the upper end of the valve, and the center is provided with a through hole of the valve rod of the valve. The lower end of the lengthening valve rod is sheathed with a connecting rod, and the lower end of the connecting rod is provided with a riveting hole which is matched with the valve rod of the valve. The lower end of the lower lengthening pipe is fixed on the upper end of the valve, and the connecting rod is inserted on the valve rod of the valve in the process of assembly so that the desired control of opening and closing is realized by operating an upper lengthening rod, and is very convenient even if the valve is deeply buried.
Description
Technical field
The utility model relates to a kind of valve and handles control piece, and especially a kind of growth device that adds of handling valve opening and closing belongs to fluid delivery pipeline facility technology field.
Background technique
The valve that is installed on the underground gas transmission and distribution network need open and close control.When valve is positioned at undergroundly than the depths, the square tenon of original valve rod upper end is far away apart from ground, handles very inconvenient.
The model utility content
The purpose of this utility model is: at the above problem that is positioned at underground than depths valve opening and closing manipulation control difficulty at present, propose a kind of valve opening and closing lengthening device, thereby the manipulation of convenient various degree of depth valves is controlled.
In order to reach above purpose, valve opening and closing lengthening device of the present utility model comprises that the upper end is shaped on the lengthening valve rod of tenon, described lengthening valve rod by Bearing Installation on the case lid base plate, the lower end of described case lid base plate is connected and goes up extension pipe, described upward extension pipe socket is fixed on down on the extension pipe, and the bottom of described extension pipe down and valve upper end match, and the center is shaped on the valve rod perforation, the lower end of described lengthening valve rod is socketed with extension bar, and the lower end of described extension bar is shaped on the mortise that matches with valve rod.
During assembling, will descend the extension pipe lower end to be fixed on the valve upper-end surface, extension bar is inserted on the valve rod.So, by handling extension bar, can realize required keying control, though valve bury darker, also very convenient.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is an embodiment's of the utility model a structural representation.
Fig. 2 is the side view of Fig. 1.
Embodiment
Embodiment one
The valve opening and closing of present embodiment lengthening device as shown in Figure 1, the lengthening valve rod 6 of the side of being shaped on, upper end tenon by Bearing Installation on case lid base plate 5.The lower end of this case lid base plate is connected and goes up extension pipe 4.Should go up extension pipe 4 and be sleeved on down outside the extension pipe 10, both sides are shaped on kidney slot, are connected by the screw 9 and the following extension pipe 10 that pass kidney slot.The flange plate 11 that the bottom of following extension pipe 10 is connected and matches with the valve upper-end surface, flange plate 11 centers are shaped on the valve rod perforation.The lower end of lengthening valve rod 6 is inserted in the endoporus of extension bar 3, circumferentially constraint.The lower end of extension bar 3 is shaped on the mortise that matches with valve rod.
During assembling, flange plate 11 is fixed on the valve upper-end surface, extension bar 3 lower ends are inserted on the valve rod, bury the ground degree of depth according to valve, regulate the relative position of upper and lower extension pipe 4 and 10, can drive valve rod, realize required valve opening and closing control easily by handling lengthening valve rod 6.
In addition, on the case lid base plate 5 of present embodiment valve opening and closing lengthening device indication case 7 is housed, while and two in-line gears that are contained in driving gear engagement on the lengthening valve rod 6 are housed in this indication case 7, the number of teeth of described two in-line gears differs a tooth, one of them and pointer are connected, another and dial are connected, and therefore no matter how valve rod rotates, and all can indicate the valve opening and closing state all the time.
