Embodiment Construction

[0028] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0029] refer to figure 1 and figure 2 , A buried valve connection device described in this embodiment, including a telescopic rotating rod 1, an upper protective cover 2, a lower protective cover 3, a connecting piece 4 and a locking assembly 5. The upper protective cover 2 and the lower protective cover 3 are sheathed on the outer periphery of the rotating rod 1 respectively. The connecting piece 4 is fixed in the rotating rod 1 . The connecting piece 4 has elastic deformation capability, and it is used to limit the telescopic length of the rotating rod 1 . The locking assembly 5 is fixedly connected with the upper protective case 2 and the lower protective case 3 in a detachable manner.

[0030] The rotating rod 1 is hollow inside, and a connecting hole 10 for fixing the connecting piece 4 is opened on the side wall of the rotating rod 1 . The r...

Abstract

The invention relates to an underground valve connecting device which comprises a telescopic rotating rod, an upper protecting sleeve and a lower protecting sleeve. The periphery of the rotating rod is respectively sleeved with the upper protecting sleeve and the lower protecting sleeve. The underground valve connecting device further comprises a connecting piece and a locking module. The connecting piece is fixed in the rotating rod, the locking module is detachably fixedly connected with the upper protecting sleeve and the lower protecting sleeve, the rotating rod is hollow, a side wall of the rotating rod is provided with a connecting hole for fixing the connecting piece, the connecting piece comprises a connecting part having elastic deformation capability and an abutting-against part fixed at the end of the connecting part, the abutting-against part penetrates the connecting hole of the rotating rod, and the connecting part is located in the rotating rod. The underground length of the rotating rod of the underground valve connecting device can be freely adjusted, and accordingly the underground valve connecting device is convenient to install and high in installing efficiency.

Description

technical field [0001] The invention relates to the technical field of buried valves, in particular to a connection device for buried valves. Background technique [0002] Because buried valves are widely used in the two fields of pipeline gas transportation and underground waterway transportation. Therefore, the demand for buried devices in the market continues to increase. The operator can drive the buried valve through the buried device on the surface to control the transportation of the pipeline. [0003] At present, buried valves are installed in different regions, and their buried depths are different. Therefore, corresponding support pipes and other components are needed to connect the driving device on the surface with the buried valve. In the prior art, the buried depth of the buried valve is usually firstly calculated accurately according to the geology, and the length of the support pipe is adjusted according to the calculation results. . [0004] For example,...
