Abstract
The invention discloses a compound tooth maze screw seal. Wherein, the invention can work based on the screw tooth; and present maze screw seal tooth has only single tooth type; the inventive screw type can be rectangle, triangle, and round, etc, while each type has special advantages and defects; therefore, the inventive compound tooth maze screw seal can fully utilize the properties of each screw tooth type.
Description
Technical field the present invention relates to a kind of composite tooth-shape labyrinth spiral sealing, belongs to general engineering equipment technical field.
Background technique is present, the labyrinth spiral sealing of domestic and international design, and the patent No. is ZL91202941.2, its structure is made up of rotor 1 and stator 2 as shown in Figure 1.
Labyrinth spiral sealing is made up of screwed rotor and stator, is a kind of reliable non-contact sealing.This labyrinth spiral sealing is to rely on thread tooth type work.The screw thread of Fig. 1 rotor 1 and stator 2 all is single flute profile.The labyrinth spiral sealing thread tooth type can be designed to rectangle, triangle, trapezoidal and semicircle etc. respectively.
Studies have shown that every kind of thread tooth type all has the particular performances advantage, but every kind of thread tooth type all has fatal deficiency.The thread tooth type design of labyrinth spiral sealing is crucial.
Summary of the invention the objective of the invention is to design a kind of composite tooth-shape labyrinth spiral sealing.Be a part of screw thread that will have single thread tooth type Fig. 1 rotor 1, change other thread tooth type into, be designed to the composite tooth-shape rotor 1 of Fig. 2.Stator 2 thread tooth types of Fig. 2 and stator 2 thread tooth types of Fig. 1 maintain the original state.
Newly-designed composite tooth-shape labyrinth spiral sealing is made up of rotor 1 and the stator 2 of Fig. 2.
Newly-designed composite tooth-shape labyrinth spiral sealing can be given full play to the performance advantage of every kind of thread tooth type.
Description of drawings Fig. 1 is the structural representation of prior art, and Fig. 2 is a structural representation of the present invention.
Embodiment is below in conjunction with Fig. 2 introduction, and composite tooth-shape labyrinth spiral sealing of the present invention is made up of rotor 1 and the stator 2 of Fig. 2.
Specifically introduce content of the present invention.Be a part of screw thread that Fig. 1 has been had the rotor 1 of single thread tooth type, change other thread tooth type into, be designed to the composite tooth-shape rotor 1 of Fig. 2.One embodiment of the present of invention thread tooth type is triangle and semicircle compound composition.
Claims (1)
1, a kind of composite tooth-shape labyrinth spiral sealing comprises rotor and stator, and the thread tooth type that it is characterized in that rotor is by two kinds of flute profile compound compositions.
