Abstract
The utility model provides a spring self -interacting spheroid rotary joint is including casing, pad, sealing washer, sleeve, supported flange, bolt, nut, bullet pad, spheroid, hold -carrying orchid, characterized by: still include the spring, the spring is preassembleed between two bullet pads on the bolt, and the spring one end of suit on the bolt is by a nut fastening connection in the bullet pad outside, the other end and the bullet pad fastening connection by sheatheeing in at axial positioning, fastening connection is with it applyed after certain pretightning force through nut, bullet pad, spring to the sealing washer to the supported flange of suit on the bolt, the sleeve suit is in the outside of casing, the pad is installed between casing and sealing washer, and the sealing washer is installed in the spheroidal outside, spheroid and the blue fixed connection of hold -carrying. The utility model has the advantages that: simple structure, operated steadily, realized that the wearing and tearing of automatic compensation sealing washer reach sealed effect for spheroid rotary joint does not have the leakage safe handling.
Description
Technical field:
The utility model relates to the connection area of the evaporated cooling system of converter and walking beam heating furnace and various high temperature, high pressure steam pipeline, particularly relates to the pipe-menders that the cooling component that does cyclical movement on oven and fixed component are connected.
Background technique:
In the prior art, pipe-menders is iron and steel, chemical industry, oil, generating, the industry such as heat supply has high temperature, high pressure needs critical component indispensable in the equipment of motion.In remote heat energy transportation process, the higher heat-energy losses of temperature, pressure is fewer, like this with regard to needing to bear high temperature, the pipe coupling of high pressure comes safeguards system stable operation and safe operation, the huge stress that minimizing system produces because expanding with heat and contract with cold.All promote heat, electric shaft technology in large integrated enterprise both at home and abroad at present, the enterprise that can produce heat energy can directly utilize cogeneration, heating, and more high usage is higher for the pressure of waste heat, temperature.In iron and steel enterprise, walking beam furnace is just equivalent to a boiler, the high temperature produced in evaporated cooling system, high pressure steam are directly used in generating and heating, the interlock of such iron and steel enterprise and power plant can be produced steel products and can be produced power product again, the waste heat produced during iron and steel enterprise is produced is fully utilized, and reaches the object of energy-saving and emission-reduction, cost efficiency.But existing pipe-menders is in walking beam furnace gasification cooling system operation process, and seal ring often can make pipe-menders leak because occurring wearing clearance to increase, the normal operation that impact is produced.
Summary of the invention:
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of simple and reliable, easy to operate, economical and efficient, the leak free pipe-menders of guarantee safe handling.
The utility model solves the scheme that its technical problem adopts: provide a kind of spring self-regulation pipe-menders, comprise housing, pad, seal ring, sleeve, supported flange, bolt, nut, bullet pad, spheroid, end flange; It is characterized in that: also comprise spring; Spring is contained between two bullet pads on bolt in advance, is sleeved on spring one end on bolt and is connected by the fastening nuts of outside bullet pad, the other end with lean against the bullet pad that axially locating puts and be fastenedly connected; The supported flange be sleeved on bolt is fastenedly connected with it after applying certain pretightening force to seal ring by nut, bullet pad, spring; Sleeve set is in the outside of housing; Pad is arranged between housing and seal ring, and seal ring is arranged on the outside of spheroid; Spheroid is fixedly connected with end flange.Its working principle is: on supported flange clamping bolt, increase Compress Spring, in assembly process, apply the effect that a pretightening force reaches sealing by clamping bolt, supported flange to seal ring; In real-world operation process, when there is wearing and tearing, gap increase in seal ring, pipe-menders will leak, the pretightening force that now spring is applied on supported flange will be had an effect, by supported flange, a constant pressure is applied to seal ring, automatically make up the gap that seal ring produces because of wearing and tearing, reach the object of pipe-menders No leakage safe handling.
The beneficial effects of the utility model are: spring self-regulation pipe-menders, have that structure is simple, overall weight be light, characteristics of compact layout, operate steadily, uniform force, applied range, adaptable, long service life, the wearing and tearing achieving automatic compensation sealing circle reach the effect of sealing, be applicable to the requirement of large-scale continuous production, improve the utilization efficiency of equipment, there is the effect of energy-saving and emission-reduction.
Accompanying drawing illustrates:
Fig. 1 is a kind of spring self-regulation of the utility model embodiment pipe-menders structural representation.
In accompanying drawing: 1. housing; 2. pad; 3. seal ring; 4. spring; 5. sleeve; 6. supported flange; 7. bolt; 8. nut; 9. bullet pad; 10. spheroid; 11. end flange.
Embodiment:
Below in conjunction with accompanying drawing, the utility model example is described in further detail: a kind of spring self-regulation pipe-menders as shown in Figure 1, is formed 11 formed by interconnective housing 1, pad 2, seal ring 3, spring 4, sleeve 5, supported flange 6, bolt 7, nut 8, bullet pad 9, spheroid 10, end flange; Its principle is: in assembly process, apply certain pretightening force by bolt 7, spring 4, supported flange 6 pairs of seal rings 3, make it produce effect that resiliently deformable reaches sealing; In spring self-regulation pipe-menders normal operation, owing to producing relative movement between seal ring 3 and housing 1, spheroid 10, the wearing and tearing of seal ring 3 certainly will be caused to make to produce gap therebetween, and the elastic force that now spring 4 is applied on supported flange 6 will be had an effect, a constant pressure is applied by supported flange 6 pairs of seal rings 3, automatically make up the gap that seal ring produces because of wearing and tearing, reach the leak free safe handling of spring self-regulation pipe-menders.
