Background technique
In many industries such as chemical industry, light industry, iron and steel, machine-building, military project, when realizing carrying liquid medium continuously, all need pass through suitable conversion equipment between static/rotary system, promptly carry out in the water joint.The water joint is called swivel joint usually again.With present great-power electronic emission system equipment is example, the water joint is a critical component of its cooling system in equipment, by carrying out the conversion equipment that cooling medium is carried continuously through the water jacket of rotation with fixed housing, be used for the fixing cooling medium at liquid cooling station is transported to rotation by static pipe-line system pipe-line system, after the heating electron emissive system cooling to rotation, pipe-line system through rotation flow back into static pipe-line system again, returns fixedly liquid cooling station.Present water joint generally all is a coaxial structure, the runner of axial channel as liquid promptly arranged in the middle of running shaft, its radial dimension is less, and can not pass cable, the rotary seal form generally all is radial seal, usually adopt soft materials such as rubber, teflon as sealing material, what seal is compensatory relatively poor, require radial dimension bigger in addition, be subjected to very big restriction at aspects such as operating life, working pressure, rotational speed, running accuracy, sealability, high low temperature adaptabilities, can't have satisfied more and more harsher working condition.
The model utility content
At above-mentioned situation, the utility model will provide a kind of Twin channel rotation water joint device of new structure form, to solve the problem that this device of past exists.
The basic structure of the utility model Twin channel rotation water joint device is
: have axial hole and through bearing structure be arranged at the rotatable water jacket cell cube in the housing the wall side structure the footpath upwards, liftoff outer annular water channel and the internal layer water annulus that distributes that be provided with vertically of being separated by, an axial side of two water annuluss is provided with the moving joint of the outer annular water channel that is connected with rotatable outside pipe system separately and the internal layer water annulus moves joint.Wherein:
The axial opposite side of outer annular water channel is opened on a double seals chamber between water jacket cell cube and the housing, be provided with two groups of two rotary end surface seal rings that are connected with the water jacket cell cube through the drive mechanism (as simple driving pin etc.) of appropriate format respectively in opposing mode in the sealing chamber, its two opposing axial seal face places respectively are fitted with a static end face sealing ring that is connected with housing, also are provided with through pedestal to be used to make two seal faces to keep the elastic structure of fitting and contacting;
The axial opposite side of internal layer water annulus then is opened on a mechanical single seal chamber between water jacket cell cube and the housing, be provided with the rotary end surface seal ring that one group of drive mechanism through appropriate format (as simple driving pin etc.) is connected with the water jacket cell cube in the sealing chamber, and fit with its axial seal end face and be connected in the static end face sealing ring of housing, also be provided with through pedestal and be used to make its seal face elastic structure of contact that keeps fitting;
Housing position in double seals chamber and mechanical single seal chamber is provided with separately and is used for the outer annular water channel that is connected with static pipe-line system and the quiet joint of internal layer water annulus.
In said structure, moving joint of the outer annular water channel that said and rotatable outside pipe system is connected and the moving joint of internal layer water annulus are arranged on the axial same extreme direction place of water jacket cell cube with employing, are more convenient a kind of forms.
In addition, the outer annular water channel that said and rotatable outside pipe system is connected and/or the moving joint of internal layer water annulus, and all settings radially of quiet joint that are connected outer annular water channel and/or internal layer water annulus with static pipe-line system, equally also be a kind of more convenient selection form.
In said structure, saidly be used to make each seal face elastic structure of contact that keeps fitting, generally can adopt the most general and structural member such as spring widely of use.
Because in the above-mentioned Twin channel rotation water joint device, two groups of end face seal structures in said double seals chamber are provided with in opposing mode, therefore, for making its both sides sealing end face keep the elastic structure of fitting and contacting, under the situation of not getting rid of other structure that can select and/or mode, serve as better to adopt the mode in example that can be for reference.That is, by the spring structures such as same compression type spring on these two opposing rotary end surface seal rings of can acting on simultaneously in the pedestal setting between these two opposing rotary end surface seal rings.
For guaranteeing and the raising sealing effect, between the interior circle of each the rotary end surface seal ring in the above-mentioned water joint device in said double seals chamber and/or mechanical single seal chamber and the cylindrical of water jacket cell cube, also be provided with radial seal structure as static seal, as the sealing configuration or the element of various conventionally forms such as O shape rubber ring.
The groundwork process and the principle of the above-mentioned Twin channel of the utility model rotation water joint device are: when rotatable water jacket cell cube rotation and driving is arranged in the rotary end surface seal ring rotation of each end face seal chamber, its each seal face is held with corresponding stationary end face seal environmental protection all the time and is fitted tightly, and has realized the dynamic seal (packing) under the condition of running; O shape rubber seal in the rotary end surface seal ring between circle and the water jacket cell cube cylindrical etc. then forms static seal.Liquid medium outside the system (as cooling liquid) can by with the housing at place, this double seals chamber on quiet joint flow to, outer annular water channel in double seals chamber and the water jacket cell cube of flowing through is at last by flowing out with the moving joint of the outer annular water channel of water jacket cell cube rotation.The liquid medium that returns can be from entering with the moving joint of the internal layer water annulus of water jacket cell cube rotation, internal layer water annulus in the water jacket cell cube of flowing through and mechanical single seal chamber, flow out by the quiet joint on the sealing cavity shell at last, be implemented in the continuous conveying of liquid medium between static/rotary system.
Because the water joint device of the utility model said structure form is the hollow type structure, the hollow duct (can greater than 100 millimeters) of big radial dimension can be arranged, thereby can hold more cable and pass; What seal form adopted is end face seal, because the normally wear-resisting hard material of end face seal ring material, elastic structure (element) makes end face sealing ring have long-term good compensatory and sealing.Through test, adaptability and the aspect such as reliability of water joint device of the present utility model under various complexity and harsh work condition environment all demonstrated and had the outstanding and significant advantage that is better than traditional radially rotary seal greatly.
Below in conjunction with the embodiment of accompanying drawing illustrated embodiment, foregoing of the present utility model is described in further detail again.But this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following example.Do not breaking away under the above-mentioned technological thought situation of the utility model, various replacements or change according to ordinary skill knowledge and customary means are made all should be included in the scope of the present utility model.
