Description

Water turbine expansion joint structure
Technical field
The utility model relates to a kind of structure allowing the adjustment of a large amount of axis or movement, is specifically related to a kind of water turbine slip joint.
Background technique
Water turbine is one of the important electromechanical equipment in water power plant.In order to ensure the safe and reliable operation of water turbine, the water inlet of water turbine is all equiped with water intake ball valve, upstream and liaison of penstock, and downstream is connected with hydroturbine water intake spiral case.Pass through the current in this valve cut-out pressure steel pipe on the one hand when water turbine and maintenance for generation companies, ensure the safety of maintenance, effectively can cut off current, the generation of Accident prevention when exception appears in water turbine and generator on the other hand.When valve normally works, the pipeline axial that this expansion joint structure can adapt to automatically because pressure and temperature variation are brought expands or shrinks.When carrying out repair and maintenance to valve (as changed water stop ring, valve seal ring etc.), shortening slip joint length, to ensure enough spaces, meeting valve dismounting requirement.
Model utility content
The purpose of this utility model is to provide a kind of water turbine expansion joint structure, can meet the requirement that valve normally works, and also needs convenient adjustment so that inspection and maintenance valve, meets valve dismounting requirement.
For achieving the above object, the technical solution of the utility model is: water turbine expansion joint structure, comprise slip joint intubate and water inlet volute flange, described water inlet volute flange is provided with fixed via, described slip joint intubate outer end is arranged with loose flange, described loose flange offers the movable through hole corresponding with fixed via, running through in described fixed via and movable through hole has stud, and described stud stretches out the termination of loose flange and water inlet volute flange respectively by bolt-locking.
When adopting technique scheme, owing to being arranged with loose flange outside slip joint intubate, loose flange suitably can be moved in slip joint intubate, total is made all to have certain extending amount in slip joint intubate and water inlet volute flange both direction, when valve normally works, the pipeline axial that this structure can adapt to automatically because pressure and temperature variation are brought expands or shrinks.When carrying out repair and maintenance to valve, pull down the connecting bolt of slip joint and water inlet volute flange, loose flange is promoted to slip joint intubate direction, slip joint intubate is promoted to water inlet volute flange simultaneously, shorten slip joint length, to ensure enough spaces, meet valve dismounting requirement.
Further, in described slip joint intubate and be provided with O-ring seals between loose flange.O-ring seals can form good sealing effect in slip joint intubate and between loose flange.When O-ring seals damage needs to change, pull down the connecting bolt of slip joint and water inlet volute flange, slip joint intubate is motionless, is promoted by loose flange to slip joint intubate direction, until expose O shape ring recess completely, now can enclose O shape and change.
Further, seal ring is provided with on described loose flange and between water inlet volute flange.Sealing circle can form good sealing effect between loose flange and water inlet volute flange.
Further, described O-ring seals has two.Two O-ring seals are set there is dual sealing effect.
Further, described stud is stud, and the thread rotary orientation at described stud two ends is contrary.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model water turbine expansion joint structure embodiment.
Embodiment
As shown in Figure 1, the utility model water turbine expansion joint structure, includes slip joint intubate 1 and water inlet volute flange 3, water inlet volute flange 3 is provided with fixed via.Be arranged with loose flange 2 in slip joint intubate 1 outer end near water inlet volute flange 3 place, in slip joint intubate 1 and between 2 of loose flange, be provided with two O-ring seals.Loose flange 2 also offers the movable through hole corresponding with fixed via, running through in fixed via and movable through hole has stud 4, and stud 4 stretches out the termination of loose flange 2 and water inlet volute flange 3 respectively by bolt-locking.Rubber seal is provided with on loose flange 2 and between water inlet volute flange 3.
Owing to being arranged with loose flange 2 outside slip joint intubate 1, loose flange 2 suitably can be moved in slip joint intubate 1, total is made all to have certain extending amount in slip joint intubate 1 and water inlet volute flange 3 both direction, when valve normally works, the pipeline axial that this structure can adapt to automatically because pressure and temperature variation are brought expands or shrinks.When carrying out repair and maintenance to valve, pull down the connecting bolt of slip joint and water inlet volute flange 3, loose flange 2 is promoted to slip joint intubate 1 direction, slip joint intubate 1 is promoted to water inlet volute flange 3 simultaneously, shorten slip joint length, to ensure enough spaces, meet valve dismounting requirement.O-ring seals in slip joint intubate 1 and between loose flange 2, can form good sealing effect in slip joint intubate 1 and between loose flange 2.When O-ring seals damage needs to change, pull down the connecting bolt of slip joint and water inlet volute flange 3, slip joint intubate 1 is motionless, is promoted by loose flange 2 to slip joint intubate 1 direction, until expose O shape ring recess completely, now can change O shape circle.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; without departing from the concept of the premise utility; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
