The invention is simple in operation, the length of the extension bar can be adjusted according to requirement, thus construction is convenient.
Description
Technical field
The present invention relates to valve, relate in particular to welding ball valve, wherein refer in particular to the directly buried type welding ball valve that has extension bar.
Background technique
In daily life, in the engineering, the various valves that are seen everywhere carry out the ball valve that mostly is of open and close controlling for the pipeline fluid medium transport.Traditional ball valve is knockdown, and such as the two-piece type ball valve, because the sealing effect between its two valve bodies is bad, and working life, short-range missile caused that need to change frequency ratio higher, can not be applied in the demanding conveyance conduit.At present, developed welding ball valve on traditional ball valve basis, it prolongs pipe and valve body is welded as a whole, and volume is little, and is in light weight, and good sealing effect, and long service life are easy for installation.This welding ball valve generally is embedded in the following pipeline in the face of land, in order to open conveniently, then on the valve rod of welding ball valve, be provided with extension bar, so that just can open ball valve easily at certain distance overhead.Because due to our national conditions, by irregular steps the corresponding pipeline of laying according to demand again after a lot of places all are to build up the house, the pipeline of being laid distance overhead have have deeply shallow, so, the existing welding ball valve that has a fixing extension bar of length marquis sometimes will occur corresponding to the distance from the pipeline to ground, and extension bar is too short and do not reach apart from the ground rational position and cause the phenomenon of Open valve inconvenience to take place.
Summary of the invention
The technical problem to be solved in the present invention provides the welding ball valve that a kind of extension bar length can be regulated, and it can be according to laying the distance of pipeline to ground, and stretching or shortening extension bar make valve opening become simple to reach reasonable distance to ground.
For solving the problems of the technologies described above, technological scheme provided by the invention is a kind of adjustable extension bar direct burial welding ball valve, it comprises valve body, be welded on periphery wall on the described valve body and be provided with the valve rod sleeve pipe of a circle horizontal ledge, be installed in the valve rod of the control valve body switch in the described valve rod sleeve pipe, locking at described valve rod is with an extension bar device, it is characterized in that described its length of extension bar device can regulate.
Described extension bar device comprises the unlatching cover that is set in described valve rod opening end, is fixedly connected with an all-or-nothing piece with described unlatching cover, and once outer sleeve is set in the outside of described unlatching cover and all-or-nothing piece; One connects the outside that is set in described down outer sleeve and described valve rod sleeve pipe, and it is positioned at horizontal ledge top of described valve rod sleeve pipe and is undertaken spacingly by described horizontal ledge, and it is outer and with its locking that a locking nut cover is locked in the described cover that connects; One movable locking device is set in outside the described outer sleeve down and is positioned at the described top that connects cover, be fixedly connected with outer sleeve in described locking device upper end, the described outer sleeve of going up is set in described outer sleeve outside down, outer sleeve upper is fixedly connected with an opening device on described, described opening device has a rotating axis, be fixedly connected with a tube used for bottom pouring in described axis lower end, described tube used for bottom pouring is set between described outer sleeve down and the described all-or-nothing piece, at least be provided with two keyways relatively uniformly at its length direction of described tube used for bottom pouring inwall upper edge, offer the flat key of corresponding described keyway on the described all-or-nothing piece epimere outer wall, described flat key sticks in the described keyway and described keyway can move up and down with respect to described flat key, and described under external force opening device can move up and down with respect to described all-or-nothing piece.
Described locking device comprises that one is set in the cutting ferrule on the described outer sleeve down, fixedlys connected with the described outer sleeve of going up in described cutting ferrule upper end, and its lower end madial wall is an annular slope; One locking nut cover is locked on the described cutting ferrule lower end, is being provided with an annular gland that is set on the described outer sleeve down between described cutting ferrule and the described locking nut, and described annular gland simultaneously is the inclined-plane near described cutting ferrule; Between the inclined-plane of described annular gland and inclined-plane, described cutting ferrule lower end, be provided with at least four wedge-shaped blockss.
Described wedge-shaped blocks contacts the double wedge that one side is provided with the enhancing locking effect of several projectioies with described outer sleeve down.
Make tube used for bottom pouring be moved upward to suitable distance by mobile locking device, then locking along all-or-nothing piece; By rotating tube used for bottom pouring, rotate all-or-nothing piece thereby can moment of torsion be passed to all-or-nothing piece by the keyway on the tube used for bottom pouring, by all-or-nothing piece drive unlatching cover valve rod is rotated and open ball valve.
By the extruding force of rotational lock nut to gland and wedge-shaped blocks, wedge-shaped blocks is clamped on down on the outer sleeve outer wall, reach and make locking device locking on outer sleeve down.Need to elongate or when shortening extension bar, send again to move behind the open locking nut to get final product.
The present invention avoids taking time and effort the welding ball valve of the valve rod that customizes given length because extension bar can carry out the length adjusting according to needs, and its application area is wider, and the client uses more convenient simple, for the client has saved the time, has made things convenient for client's operation.
