Abstract
The utility model provides a dual spring self -interacting spheroid rotary joint is including casing, spacer, spring, pad, sealing washer, spring, sleeve, supported flange, bolt, nut, bullet pad, spheroid, hold -carrying orchid, characterized by: the spring is preassembleed in the spacer, and one end is connected bottom the casing, and the other end is connected with the pad, and the supported flange passes through the sealing washer, fills up (applys certain its emergence of pretightning force messenger elastic deformation to the spring. 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 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：
This utility model is related to evaporated cooling system and various high temperature, the high steam of converter and walking beam heating furnace
The connection area of pipeline, the cooling component being more particularly to used for doing periodic reverse motion on heating furnace is connected with fixing component
The pipe-menders of knot.
Background technology：
In the prior art, pipe-menders are that the industries such as iron and steel, chemical industry, oil, generating, heat supply have high temperature, height
Pressure needs indispensable critical component in the equipment of motion.In remote heat energy transportation, the higher heat energy of temperature, pressure
Loss is fewer, is so accomplished by bearing high temperature, the pipe joint of high pressure comes safeguards system steady operation and safe operation, reduces
The huge stress that system produces because expanding with heat and contract with cold.All promote heat, electric shaft technology, energy in large integrated enterprise both at home and abroad at present
The enterprise enough producing heat energy can directly utilize cogeneration, heating, and the pressure of waste heat, temperature more high usage is higher.Iron and steel
In enterprise, walking beam furnace is equivalent to a boiler, and in evaporated cooling system, produced high temperature, high steam are directly used
In generating electricity and heating, the linkage of such iron and steel enterprise and power plant can produce steel products and can produce power product again, make iron and steel
The waste heat that enterprise produces in producing is fully utilized, and reaches the purpose of energy-saving and emission-reduction, cost efficiency.But, existing ball
In walking beam furnace gasification cooling system operation process, sealing ring often increases body swivel because wearing clearance
And so that pipe-menders is leaked, the normal operation that impact produces.
Content of the invention：
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple and reliable, easy to operate, economic height
Effect, the guarantee leak free pipe-menders of safe handling.
The scheme that the present invention solves that its technical problem adopted is：A kind of dual spring self-regulation pipe-menders are provided,
A kind of dual spring self-regulation pipe-menders, including housing, pad, sealing ring, spring, sleeve, supported flange, bolt, nut,
Spring washer, spheroid, end flanges；It is characterized in that：Also include spacer, compression spring；Compression spring is contained in spacer in advance, is contained in spacer in advance
In compression spring one end be connected with housing bottom, the other end with pad be connected；Be sleeved on supported flange on bolt pass through nut,
Spring washer, spring apply after certain pretightning force to sealing ring, pad, compression spring, and sealing ring is made in compression spring and supported flange
With under all the time with spheroid, housing keep be in close contact；Sleeve set is in the outside of housing；Pad be arranged on spacer and sealing ring it
Between, sealing ring is arranged on the outside of spheroid；Spheroid is fixedly connected with end flanges.It is further characterized in that：Spacer is uniformly distributed
8 spiral compression springs are installed.
Operation principle of the present utility model is：In spacer, eight spiral compression springs are installed, it is in the effect of supported flange
Lower generation compression；Increase compression spring in supported flange fastening bolt, assembling process is passed through fastening bolt, compression method
The blue effect that upper and lower two sealing rings, one pretightning force of applying is reached with sealing；During real-world operation, when cooling system
When temperature and pressure reach job requirement, spheroid will produce relative displacement so that spheroid turns in the presence of temperature and pressure
In dynamic joint, lower seal loosens gap increase loss of seal effect, and now spring passes through pad to lower sealing in the presence of elastic force
Circle applies a constant force, automatically makes up and causes the gap that lower seal loosens generation to reach original sealing because of spheroid displacement
Effect；And when abrasion, gap increase in sealing ring, pipe-menders also can leak, and now spring is applied to pressure
Pretightning force on tight flange will be had an effect, and applies a constant pressure by supported flange to upper sealing ring, automatically more
Mend the gap that sealing ring produces because of abrasion, reach the purpose of pipe-menders No leakage safe handling.
The invention has the beneficial effects as follows：This dual spring self-regulation pipe-menders, have that structure is simple, overall weight
Gently, characteristics of compact layout, operate steadily, uniform force, applied range, adaptable, long service life, safe handling no lets out
The abrasion that the pipe-menders of leakage achieve automatic compensation sealing circle reaches the effect of sealing it is adaptable to large-scale continuous production
Requirement, improve the service efficiency of equipment, there is the effect of energy-saving and emission-reduction.
Brief description：
Fig. 1 is a kind of embodiment of the present invention dual spring self-regulation pipe-menders structural representation.
In accompanying drawing：1. housing；2. spacer；3. compression spring；4. pad；5. sealing ring；6. spring；7. sleeve；8. compress method
Blue；9. bolt；10. nut；11. spring washers；12. spheroids；13. end flanges.
Specific embodiment：
Below in conjunction with the accompanying drawings present example is described in further detail：A kind of dual spring self-regulation as shown in Figure 1
Pipe-menders, by interconnective housing 1, spacer 2, compression spring 3, pad 4, sealing ring 5, spring 6, sleeve 7, compression method
Blue 8, bolt 9, nut 10, spring washer 11, spheroid 12, end flanges 13 form；Its principle is：Pass through bolt 9, bullet in assembling process
Spring 6, supported flange 8 are to upper-lower seal circle 5, compression spring（3）Apply certain pretightning force so as to produce elastic deformation reach close
The effect of envelope；In dual spring self-regulation pipe-menders normal operation, when the temperature of cooling system and pressure reach
During job requirement, spheroid（12）With housing（1）There is relative displacement, lower seal（5）With housing（1）, spheroid（12）Between generation
Gap, causes sealing effectiveness to lose efficacy；Now compression spring（3）Pass through pad in the presence of elastic force（4）To lower seal（5）Apply one
Fixed pressure, compensate for causing spheroid because of operating temperature, pressure automatically（12）Displacement and produce lower seal（5）With housing（1）、
Spheroid（12）Between gap.Due to sealing ring（5）With housing（1）, spheroid（12）Between produce relative motion, certainly will cause seal
Circle（5）Abrasion make itself and housing（1）, spheroid（12）Produce gap, and now spring（6）It is applied to supported flange（8）On
Pretightning force will be had an effect, by supported flange（8）To sealing ring（5）, compression spring（3）Apply a constant pressure,
Automatically make up sealing ring（5）The gap producing because of abrasion, reaches the leak free safety of dual spring self-regulation pipe-menders
Operating.
