Embodiment
By describing technology contents of the present utility model, structure characteristics in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with mode of execution.
Refer to Fig. 1 to Fig. 5, the utility model provides a kind of distributing valve end face pneumatic tyre seal arrangement, comprise distributing valve 1, pneumatic tyre 2, back-up ring 3, quiet dish 4, disc shaft 5 and sealing gasket 6, one end face of sealing gasket 6 is connected with the interior edge face of disc shaft 5, the other end of sealing gasket 6 is connected with an end face of quiet dish 4, the other end of quiet dish 4 is connected with distributing valve 1, and be provided with pneumatic tyre 2 between quiet dish 4 and distributing valve 1, back-up ring 3 is arranged on the outer circumferential face of sealing gasket 6 and quiet dish 4.
Wherein, distributing valve is used for input and output gas, can be provided with different gas manhole appendixs, as through hole 10 and through hole 11 above distributing valve.Can by gas transfer to the interior edge face 60 of disc shaft by these manhole appendixs, and the equipment be connected with exterior edge face through the exterior edge face 62 of disc shaft carries out the connection of gas.The exterior edge face 62 of disc shaft is namely away from the end face of the rotating shaft 64 of disc shaft.Distributing valve 1, back-up ring 3, quiet dish 4 and sealing gasket 6 are all set in the rotating shaft 64 of disc shaft.Disc shaft can relative distribution valve 1, back-up ring 3, quiet dish 4 etc. rotate around the axis of disc shaft.Pneumatic tyre 2 can be made up of rubber, and structure can be the cylindrical of hollow.Back-up ring 3 is for fixing quiet dish.Sealing gasket is used for interior edge face and the quiet dish 4 of sealed disc axle 5.
In use, the rotations such as disc shaft relative distribution valve 1, back-up ring 3, quiet dish 4, gas circulates via distributing valve, quiet dish and disc shaft the utility model.Pneumatic tyre 4 inside is full of pressurized gas, makes quiet dish press to disc shaft, maintains the sealing between disc shaft and quiet dish.The utility model makes to adopt pneumatic tyre pressuring method to solve the problem of spring pressurization fatigue failure, and the quiet dish pressurization needed for distributing valve end face seal provides stable and adjustable pressure, to ensure that distributing valve end face seal reaches the seal request of equipment needs.
What pneumatic tyre was concrete arranges and can arrange according to the actual needs, and in certain embodiments, as shown in Figure 4, the pneumatic tyre between described quiet dish and distributing valve is arrange around disc shaft axis.Namely pneumatic tyre can be a circle concentric with disc shaft, and such structure is simple, better stressed.
In certain embodiments, described quiet dish with distributing valve is provided with corresponding vent, described pneumatic tyre is arrange around vent.As shown in Figure 5, include vent 13 and vent 14, pneumatic tyre is arranged around vent, and like this, sometimes different vents needs different pressure, can realize different pressure by different pneumatic tyres.And the sealing that can ensure vent is better set around vent.
The utility model does not limit the number of pneumatic tyre, and in certain embodiments, as shown in Figure 5, the quantity of described pneumatic tyre is two or more.
In certain embodiments, the utility model also comprises pneumatic tyre pressure adjusting system, and described pneumatic tyre pressure adjusting system is connected with pneumatic tyre.Pneumatic tyre pressure adjusting system is for realizing the adjustment to pneumatic tyre pressure.
Pneumatic tyre pressure adjusting system has multiple implementation, and as being an air compressor, air compressor is connected with pneumatic tyre, namely can realize the adjustment to pneumatic tyre pressure.In certain embodiments, described pneumatic tyre pressure adjusting system comprises the first pressure regulator valve 70, two-way electromagnetic valve 72 and tracheae 74, one end of described first pressure regulator valve is connected with pneumatic tyre by tracheae, the described the other end of the first pressure regulator valve is connected with one end of two-way electromagnetic valve, and the other end of two-way electromagnetic valve is used for being connected with air compressor.The circulation of pressurized gas can be controlled by two-way electromagnetic valve, the control to pressure can be realized by the first pressure regulator valve, reach the object to pneumatic tyre pressure adjusting.
When being two for pneumatic tyre quantity, described pneumatic tyre pressure adjusting system also comprises the second pressure regulator valve 76, three-way union 78, two pneumatic tyres are connected with three-way union respectively by the first pressure regulator valve, the second pressure regulator valve, and three-way union is connected with two-way electromagnetic valve again.Like this, the adjustment to different pneumatic tyre pressure can be realized by the first pressure regulator valve and the second pressure regulator valve, meanwhile, an air compressor can be shared, improve Utilization ratio.Certainly, when pneumatic tyre quantity is multiple, the control to more pneumatic tyre pressure is realized by more three-way union and pressure regulator valve.
The pressurization of quiet dish adopts pneumatic tyre pressuring method to pressurize to the different nip of distributing valve.Disc shaft is divided into negative pressure chamber and plemum by distributing valve, because disc shaft is different with the pressure in plemum region to the negative pressure chamber region of distributing valve end face in rotation process, therefore regulated because disc shaft air distributes the problem of the uneven pressure inequality caused by the different pressures of pressure regulator valve adjustment plemum pneumatic tyre and negative pressure chamber's pneumatic tyre.Further, can be different to the pressure of distributing valve end face according to vacuum multi-disc thickner concentration process disc shaft, the pressure of adjustment pneumatic tyre is to meet the requirement of distributing valve end face seal.
The foregoing is only embodiment of the present utility model; not thereby scope of patent protection of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
