Abstract
The utility model discloses a directly-buried butterfly valve mounting structure. The directly-buried butterfly valve mounting structure comprises a well casing; a worm-gear case is arranged at the upper part in well casing; a handwheel is arranged on one side of the worm-gear case; the lower end of the worm-gear case is fixed to a connecting rod; the other end of the connecting rod extends into the underground to be connected with a butterfly valve directly buried underground; a protective sleeve covers the connecting rod; the butterfly valve is sleeved with a steel plate box; a hole is formed in the upper end of the steel plate box, and the steel plate box is in sealing connection with the lower end of the protective sleeve along the periphery of the hole; the upper end of the protective sleeve is in sealing connection with the bottom of the worm-gear case; a heat insulating material is filled between the butterfly valve and the steel plate box; the lower end of the steel plate box is in a shape of downwards convex arc; a layer of plain concrete cushion is arranged at the lower part of the well casing and surrounds the protective sleeve. The directly-buried butterfly valve mounting structure greatly facilitates operation and the maintenance of pipe conveying staff, can protect the valve, and can avoid influence on the opening of the valve due to drying of a turbine runner lubricant, which is caused by high steam temperature.
Description
Technical field
The utility model belongs to heating field, is specifically related to a kind of butterfly valve Direct buried structure.
Background technique
Original steam directly buried pipeline valve valve handle and pipeline are arranged on same absolute altitude, and buried depth is darker, and this kind of method exists following shortcoming: rainy day valve well water inlet infringement valve, and cause the road phenomenon that " hazes " serious, and management maintenance difficulty is large, potential safety hazard is large.
Summary of the invention
The purpose of this utility model is to provide a kind of butterfly valve Direct buried structure, adopt and extend connecting rod and will on Worm gear case, move, at the prefabricated lengthening connecting rod of valve producer and Worm gear case, so not only guaranteed the concentricity of self-control connecting rod, also avoided turbine oiling agent to affect the unlatching of valve because of the high mummification of vapor (steam) temperature, this innovation solved a large hidden danger in operation maintenance.
For achieving the above object, the utility model has adopted following technological scheme:
Butterfly valve Direct buried structure, it is characterized in that: include pit shaft, in pit shaft, top is provided with Worm gear case, one side of Worm gear case is provided with handwheel, the lower end of Worm gear case is fixed with connecting rod, the other end of connecting rod stretches to underground and is connected in underground butterfly valve with direct-burried, connecting rod is covered with protection sleeve outward, butterfly valve is arranged with steel plate box outward, the upper end perforate of steel plate box is also tightly connected along the surrounding in hole and the lower end of protection sleeve, the upper end of protection sleeve is connected with the sealed bottom of turbine box, between butterfly valve and steel plate box, be filled with thermal insulating material, the lower end of steel plate box is the arc protruding downwards, the below of pit shaft is provided with a laminin concrete bed course around protection sleeve.
The beneficial effects of the utility model are:
The utility model greatly facilitates fortune pipe personnel Operation and Maintenance, protected valve, has also avoided turbine oiling agent to affect the unlatching of valve because of the high mummification of vapor (steam) temperature.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
