Abstract
The utility model provides a conduct expansion joint with adjustable seal compression amount so as to solve the problems that in the prior art, the seal ring compression amount of an expansion joint seal piece cannot be adjusted, water leakage is prone to occurring, and the operating of a machine set is influenced and the like. The conduct expansion joint with the adjustable seal compression amount comprises a flange and seal rings. A seal ring I and a seal ring II are arranged on the inner side face of the back side of the flange, the seal ring I and the seal ring II are respectively arranged in the step and the groove of the inner side face of the back side of the flange, an adjusting pressing plate is arranged on the step of the seal ring I, and an adjusting bolt is arranged on the adjusting pressing plate. The conduct expansion joint with the adjustable seal compression amount has the advantages of adopting a seal mode with the adjustable compression amount, achieving the adjustment of the seal compression amount without shutting down and dismounting a machine, preventing water leakage, and guaranteeing the operation of the machine set.
Description
Technical field
The utility model relates to a kind of adjustable conduit slip joint, specially refers to the adjustable conduit slip joint of a kind of seal compression.
Background technique
Slip joint is mainly used in inlet valve mechanism in the water power plant, and its effect is to be convenient to install and the maintenance main valve, can eliminate the distortion that produces due to cold and hot simultaneously.The slip joint Sealing of prior art is located in the endoporus of flange, and the seal ring decrement can't be regulated, and as occurring leaking, only has the maintenance of shutdown after install in the power station; After using a period of time, after the slip joint sealing part abrasion, decrement reduces, and easily occurs leaking, and affects unit operation.Obviously, prior art slip joint Sealing exists the seal ring decrement and can't regulate, and easily occurs leaking, and affects the problems such as unit operation.
The model utility content
Can't regulate for the seal ring decrement that solves the existence of prior art slip joint Sealing, easily occur leaking, affect the problems such as unit operation.The adjustable conduit slip joint of this a kind of seal compression of practical new proposition.
The adjustable conduit slip joint of a kind of seal compression, comprise flange, seal ring, the inner side surface at the flange back side is provided with seal ring I and seal ring II, seal ring I and seal ring II are successively set on respectively in the step and groove of inner side surface at the flange back side, step place at seal ring I is provided with the adjusting pressing plate, regulates on pressing plate and is provided with adjusting bolt.
The useful technique effect of the adjustable conduit slip joint of the utility model seal compression is to adopt seal compression can regulate form, realizes not shutting down, not dismantling and can regulate seal compression, prevents from leaking, and guarantees unit operation.
Description of drawings
Accompanying drawing 1 is the structural representation of the adjustable conduit slip joint of the utility model seal compression;
Accompanying drawing 2 is the A place enlarged view of accompanying drawing 1.
Below in conjunction with the drawings and specific embodiments, the adjustable conduit slip joint of the utility model seal compression is further described.
Embodiment
Accompanying drawing 1 is the structural representation of the adjustable conduit slip joint of the utility model seal compression, and accompanying drawing 2 is the A place enlarged view of accompanying drawing 1, and in figure, 1 is flange, and 2 is seal ring I, and 3 is seal ring II, and 4 is adjusting bolt, and 5 for regulating pressing plate.As seen from the figure, the adjustable conduit slip joint of a kind of seal compression, comprise flange 1, seal ring I2, seal ring II3, the inner side surface at flange 1 back side is provided with seal ring I2 and seal ring II3, seal ring I2 and seal ring II3 are successively set on respectively in the step and groove of inner side surface at flange 1 back side, be provided with at the step place of seal ring I2 and regulate pressing plate 5, regulate on pressing plate 5 and be provided with adjusting bolt 4.Regulate pressing plate 5 and realize seal action at the control lower compression seal ring I2 of adjusting bolt 4, seal ring II3 is arranged in the groove of flange 1 back side inner side surface, increases sealing reliability.Because adjusting bolt 4 can externally be regulated, thereby realizing not shutting down to control seal ring I2 decrement at any time, prevents from leaking.
The useful technique effect of the adjustable conduit slip joint of the utility model seal compression is to adopt seal compression can regulate form, realizes not shutting down, not dismantling and can regulate seal compression, prevents from leaking, and guarantees unit operation.
