Abstract
The utility model provides a sealing structure, including installing the sealing member outside the function piece, sealing member activity suit is in outside the function piece. The utility model has the advantages of be swing joint between sealing member and the function piece, not only the assembly is very convenient, can not destroy the structure of function piece, moreover the sealing member can automatically regulated with treat the laminating degree between the sealed face, sealed effectual, moreover the sealing member is lower with the requirement of the post -installation axiality of function piece, greatly reduced manufacturing cost.
Description
Technical field
This utility model relates to a kind of sealing structure.
Background technology
The most conventional sealing structure, mainly includes the sealing member being fixedly mounted on outside functor, and it is outer or one-body molded with functor that sealing member is generally fixed to functor.Seal structure to when needing the mechanism sealed to seal, typically there is in mechanism to be sealed the intercommunicating pore connected between the chamber that two force value are different, be formed with to be sealed on the side of intercommunicating pore, the end face outside of sealing member be sealing surface and be adjacent to face to be sealed thus realize seal.Owing to sealing member and functor are one-body molded or interference fit forms a fixed connection, because producing or assembly relation, sealing member is unable to reach desirable with the axiality of functor, and between the sealing surface of sealing member and to be sealed of mechanism to be sealed, use hard sealing, if the slightly deviation of the axiality between sealing member and functor, the tilting of the most to be sealed of sealing surface will be caused, there is gap between sealing surface and to be sealed, and then cause the seal failure between sealing surface and to be sealed.If it addition, sealing member and functor use one-body molded, then can be higher to the requirement on machining accuracy of whole product, improve production cost；If sealing member and functor use interference fit to connect, it is easy to destroy the structure of functor when being assembled on functor by sealing member, thus causes the function imperfection of functor or suffer damage.
Summary of the invention
There is above-mentioned deficiency in prior art to overcome, this utility model provides a kind of simple and compact for structure, low cost, easy for installation, the sealing structure of good sealing effect.
The technical scheme in the invention for solving the technical problem is: a kind of sealing structure, including the sealing member being arranged on outside functor, described sealing member movable set is outside described functor.
Further, described functor is outside equipped with and described sealing member being limited on described functor and ensures, described sealing member can the movable position limiting structure of the most described functor.
Further, described position limiting structure includes recessed stopper slot on the outer wall of described functor, the inwall of described sealing member stretches in described stopper slot, and matched in clearance between inwall and the diapire of described stopper slot of described sealing member, the width dimensions of described sealing member is less than the width dimensions of described stopper slot, and width dimensions here refers to along the size that it is axial.
Further, described position limiting structure includes that at least one circle projection spacing preiection and at least on the outer wall of described functor encloses recessed limited impression on the inwall of described sealing member, the number of spacing preiection is equal to the number of limited impression, described spacing preiection one_to_one corresponding stretches in described limited impression, and matched in clearance between described spacing preiection and described limited impression, matched in clearance between inwall and the outer wall of described functor of described sealing member.
Further, described position limiting structure includes that at least one circle projection spacing preiection and at least on the inwall of described sealing member encloses recessed limited impression on the outer wall of described functor, the number of spacing preiection is equal to the number of limited impression, described spacing preiection one_to_one corresponding stretches in described limited impression, and matched in clearance between described spacing preiection and described limited impression, matched in clearance between inwall and the outer wall of described functor of described sealing member.
Further, described position limiting structure includes two circle projections spacing preiection on the outer wall of described functor, described sealing member is placed between two described spacing preiections, and the internal diameter size of described sealing member is less than the outside dimension of described spacing preiection, the width dimensions of described sealing member is less than the distance between two described spacing preiections, here width dimensions refers to along the size that it is axial, matched in clearance between inwall and the outer wall of described functor of described sealing member.
Further, described position limiting structure includes that the shaft shoulder and being located on the outer wall of described functor is fixed on the block piece on the outer wall of described functor, described sealing member is arranged between the described shaft shoulder and described block piece, and the width dimensions of described sealing member is less than the distance between the described shaft shoulder and described block piece, here width dimensions refers to along the size that it is axial, matched in clearance between inwall and the outer wall of described functor of described sealing member.
Further, the outer wall of described functor is provided with draw-in groove, and described block piece is the collar being stuck in described draw-in groove.
Further, the outer wall of described functor is provided with screw thread, and described block piece is to be arranged in the nut at described screw thread.
Further, this utility model also provides for a kind of application sealing structure, the most described functor is temperature-sensing element, described temperature-sensing element includes the housing with upper shed, lid is located at the upper cover of the opening part of this housing, and the temperature-sensitive main body being located in this housing, this temperature-sensitive main body includes that in described housing and upper end is pressed on the sebific duct between described upper cover and the top of housing in lower end, the temperature-sensitive thing being filled between the outer wall of this sebific duct and the inwall of described housing, and it is slidably installed in the push rod in this sebific duct, the upper end of this push rod is through described upper cover and stretches out outside described upper cover, described sealing member it is movably installed with outside described housing.
This utility model is in use, functor is slidably installed in mechanism to be sealed, the lower surface of sealing member is sealing surface just to be sealed at the intercommunicating pore of mechanism to be sealed, when needing to seal, functor is applied a power so that functor band dynamic seal is near to be sealed, sealing surface can fit tightly with face to be sealed under the effect of thrust, it is achieved seals；When need not seal, to functor one reverse power of applying so that functor band dynamic seal is away to be sealed, sealing surface separates with to be sealed, thus opens intercommunicating pore.Because sealing member is movably arranged on outside functor, even if sealing member and the axiality slightly deviation of functor, or the axiality slightly deviation that sealing member is with to be sealed of mechanism to be sealed, or the axiality slightly deviation that functor is with to be sealed of mechanism to be sealed, sealing member can be adjusted automatically, it is ensured that the laminating degree between sealing surface and to be sealed, good sealing effect, and be flexibly connected between sealing member with functor, assemble very convenient, and production cost is low.This sealing structure can be widely used in the mechanism needing to seal, the sealing in the various fields such as such as oil, petrochemical industry, chemical industry, metallurgy, electric power, water conservancy, urban construction, machinery, coal, food, air-conditioning, HVAC.
