Abstract
A kind of center swivel joint for turbojet fire engine, it includes water pipe, it is cylindrical that different two sections of diameter is formed with water pipe, rotatably install one on different cylindrical of two diameters and against round platform rank is each and choose to install joint, there is annular chamber on swivel joint, in the oral area of annular chamber annular cover plate is fixed with bolt, sealing ring is set to seal between annular cover plate and the internal orifice and collar extension of annular chamber, the inlet hole and outlet opening communicated with internal toroidal cavities is formed with the outside of swivel joint, in the utility model, the position of sealing is less, sealing engagement face is all to be immovably fixed composition surface, it is not only simple in construction, especially sealing effectiveness is excellent, it is not susceptible to sealing ring damage, and the security incident thereby resulted in.
Description
Technical field
A kind of centre revolving joint is the utility model is related to, especially a kind of whirlpool spray suitable on various motor vehicles and machines disappears
Anti- car centre revolving joint.
Background technology
The fire-fighting operation device of turbojet fire engine is fixed on automobile chassis by pivoting support, needed for its turbojet engine
Fuel oil (diesel oil or kerosene), the hydraulic oil needed for hydraulic-driven, the water etc. of fire-fighting is stored on automobile chassis；Spray fire-fighting in whirlpool
During fire-fighting operation, its apparatus for work can all be turned round car as needed at any time.Therefore, it is necessary in automobile chassis with disappearing
One centre revolving joint be easy to fuel oil, hydraulic oil and water while passed through is set between anti-apparatus for work.
At present, used centre revolving joint is not used to whirlpool spray and disappeared car on various motor vehicles and machines, and its subject matter is such as
Under：(1) it is only used for the connection of hydraulic oil pipe, it is impossible to while realize the connection of three kinds of fuel oil, hydraulic oil and water fluid pipelines；
(2) its sealing influences sealing effectiveness and seal durability to the bad adaptability of diesel oil, kerosene；(3) install fixed form with
The applying working condition of turbojet fire engine requires incompatible；(4) volume bulkiness, the fluid flow passed through are small.Therefore, China Patent No.
For：201010215997.4 Authorization Notice No. CN101893144B, entitled " center swivel joint for turbojet fire engine " is open
The technology of drawbacks described above can effectively be overcome, still, the existing major defect of the technology is that the revolution for needing to seal combines
Face is more, especially seals on the faying face for being all provided in and needing mutually to rotate, not only complicated, can especially cause close
Seal sealing effectiveness is bad, is easily damaged, and thereby results in leakage and trigger corresponding accident.
Utility model content
The purpose of this utility model is：For the disadvantages mentioned above in the presence of prior art, the utility model provides one
The new center swivel joint for turbojet fire engine of kind, overcomes the drawbacks described above present in prior art.
Technical scheme is used by the utility model realizes above-mentioned purpose：A kind of described turbojet fire engine center steering
Joint, it includes water pipe（1）, it is characterized in that：In described water pipe（1）On to be formed with different two sections of diameter cylindrical, by
This forms two round platform ranks（11）, on different cylindrical of two diameters and abut round platform rank（11）Respectively rotatably install one
It is individual to choose to install joint（2）, described swivel joint（2）It is upper that there is annular chamber（7）, in annular chamber（7）Oral area bolt（6）It is fixed
There is annular cover plate（3）, annular cover plate（3）With annular chamber（7）Internal orifice and collar extension between small O-ring seal is set（5）With big ring
Shape sealing ring（4）To seal, in swivel joint（2）Outside be formed with and internal toroidal cavities（7）The inlet hole communicated（8）With outlet
Hole（9）, in order to prevent swivel joint（2）In water pipe（1）Axis direction jump, in water pipe（1）It is cylindrical on be provided with a grade ring
（10）, further, in order to ensure swivel joint（2）In water pipe（1）On reliable rotation, in swivel joint（2）Endoporus with
Water pipe（1）External diameter between bearing is set（2）, in the utility model, two swivel joints（2）In, one of them is by entering
Oral pore（8）With outlet opening（9）It is connected with fuel oil, another is then connected with hydraulic oil.
Beneficial effect：In the utility model, because the position of sealing is less, moreover, all sealing engagement faces are all not
Movable fixed engagement face, own, not only simple in construction, especially sealing effectiveness is excellent, is not susceptible to sealing ring damage, and
The security incident thereby resulted in.
Brief description of the drawings
Fig. 1 is structure principle chart of the present utility model.
Shown in figure：1 it is water pipe, 2 be swivel joint, 3 be annular cover plate, 4 be big O-ring seal, 5 is that small annular is close
Seal, 6 be bolt, 7 be annular chamber, 8 be inlet hole, 9 be outlet opening, 10 be a grade ring, 11 be round platform rank.
