Abstract
The invention relates to an expansion joint, in particular to a ballast expansion joint, consisting of flanges (1), a hexagon bolt (2), a body (3) a stainless steel stop screw (4), sealing rings (5) and a screw nut (6), wherein, the stainless steel stop screw (4) is arranged in the body (3), the sealing rings (5) are arranged at the two ends of the body (3), the flanges (1) are arranged at the outside of the sealing rings (5), the flanges (1) at the two sides are connected by the hexagon bolt (2) and fixed by the screw nut (6) at the outside of the flanges (1). With minimum compensation, the ballast expansion joint of the invention can absorb large displacement and bear systematic high pressure; the sealing effect is good, frequency for maintenance and replacement is reduced, thus ensuring coaxiality of the main pipes at the two ends of the expansion joint.
Description
Technical field:
The present invention relates to a kind of expansion joint, be specifically related to a kind of ballast expansion joint.
Background technique:
Expansion joint is the new product that equipment such as pump, valve, pipeline are connected with pipeline, by full bolt they is coupled together, and makes its one-tenth as a whole, and certain displacement amount is arranged, and when work, can pass end thrust also to whole tubing.So not only increase work efficiency, and pipe-line equipments such as pump, valve are played certain protective role.
Understanding usually than long lines in the boats and ships pipe is done add expansion joint at pipeline; be in order to guarantee that pipeline can be owing to moving of pipeline causes the leakage of joint when participating in full ship longitudinal strength like this; and can cause hull vibrations, distortion, flexible during ship's navigation, expansion joint can be played compensating action.
Present expansion joint just cannot continue to adjust impacting force behind sealing wear, do not reach sealing effect, increased the frequency of maintain and replace, when initial the installation, have radial missing, can not guarantee the coaxality of the main pipe at expansion joint two ends, when pipeline was longer, the pressure of ballasting system and displacement increased, and needed very big compensation rate to absorb.
Summary of the invention:
The purpose of this invention is to provide a kind of ballast expansion joint, it can absorb big displacement and bear system high pressure with the compensation rate of minimum, good sealing effect, and the frequency of maintain and replace reduces, and guarantees the coaxality of expansion joint two ends main pipe.
In order to solve the existing problem of background technique, the present invention is by the following technical solutions: it is made up of flange 1, hex head bolt 2, body 3, stainless steel clamping screw 4, seal ring 5 and nut 6, be provided with stainless steel clamping screw 4 in the middle of the body 3, body 3 two ends are provided with seal ring 5, seal ring 5 arranged outside have flange 1, the flange 1 of both sides is connected by hex head bolt 2, and fixing with nut 6 in flange 1 outside.
The present invention embeds stuffing box packing at double-layer pipe, stuffing box packing tightly is wrapped in system's main pipe and reaches the purpose that seals and carry, stuffing box packing is regulated by gland, behind sealing wear, can adjust impacting force, make it to reach sealing effect, reduce the frequency of maintain and replace, owing to adopt rigid casing, avoid the radial missing when initial the installation, guaranteed the coaxality of expansion joint two ends main pipe.
The present invention can absorb big displacement and bear system high pressure with the compensation rate of minimum, good sealing effect, and the frequency of maintain and replace reduces, and guarantees the coaxality of expansion joint two ends main pipe.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Embodiment:
With reference to Fig. 1, this embodiment is by the following technical solutions: it is made up of flange 1, hex head bolt 2, body 3, stainless steel clamping screw 4, seal ring 5 and nut 6, be provided with stainless steel clamping screw 4 in the middle of the body 3, body 3 two ends are provided with seal ring 5, seal ring 5 arranged outside have flange 1, the flange 1 of both sides is connected by hex head bolt 2, and fixing with nut 6 in flange 1 outside.
This embodiment embeds stuffing box packing at double-layer pipe, stuffing box packing tightly is wrapped in system's main pipe and reaches the purpose that seals and carry, stuffing box packing is regulated by gland, behind sealing wear, can adjust impacting force, make it to reach sealing effect, reduce the frequency of maintain and replace, owing to adopt rigid casing, avoid the radial missing when initial the installation, guaranteed the coaxality of expansion joint two ends main pipe.
This embodiment can absorb big displacement and bear system high pressure with the compensation rate of minimum, good sealing effect, and the frequency of maintain and replace reduces, and guarantees the coaxality of expansion joint two ends main pipe.
