Description
Technical field
This utility model is related to the sealing structure of motor, and in particular to a kind of new drain valve sealing structure.
Background technology
Motor is commonly called as motor, to refer to and realize electric energy conversion or a kind of calutron for transmitting according to the law of electromagnetic induction.Electricity
The Main Function of machine is to produce driving torque, used as electrical appliance or the power source of various machineries.At present, in electromechanics trade, electricity
Sealed using 55 degree of taper thread sealings and O-ring more than the sealing means of drain valve on machine.Taper pipe thread has 16:1 taper,
Based on this characteristic so that the raw material band being wrapped on screw thread can be distributed evenly on screw thread, with better seal.
O-ring sealing is sealed as a kind of extrusion pressing type, and elastic deformation occurs by sealing member, and contact pressure is caused on sealing contact surface
Power, contact pressure are intrinsic pressure more than sealed medium, play excellent sealing effect.
55 degree of taper thread sealings are compared with O-ring sealing, and both sealing means respectively have pluses and minuses：Taper thread is tightly connected
Intensity and Reliability comparotive are good, but the difficulty of processing of inside tapered thread is relatively large, and in actual applications, erecting yard bolt
Tightening moment be difficult to control, easily there is the problem that bolt falls into water channel.O-ring sealing is more satisfactory sealing means,
Seal compared to taper thread, its cost is relatively low, but synthetic rubber used by O-ring belongs to viscoelastic material, the compression for setting in the early stage
Amount and resilience block capability Jing long-time are used, and can be produced permanent deformation and gradually be lost, finally cause leakage, affect the motor longevity
Life.So, it is badly in need of a kind of being not only convenient to process and mount but also low cost, the drain valve sealing structure of long service life.
Utility model content
This utility model purpose is to provide a kind of new drain valve sealing structure, to solve the sealing of fluid-cooled electrical machine drain valve
The middle security hidden trouble for seal failure occur, extends motor service life.
To reach above-mentioned purpose, base case of the present utility model is as follows：A kind of new drain valve sealing structure, including liquid
Cold seat, drain valve bolt and bonded washer, the drain valve bolt are coordinated with liquid cold seat screw thread, and the bonded washer is located at
Between liquid cold seat and drain valve bolt；The bonded washer includes inner ring and outer ring, being provided with annular projection on the inside of the outer ring,
Annular groove is provided with the outside of the inner ring, the annular projection external diameter is equal with annular groove internal diameter size, the annular groove
It is embedded on annular projection；Sealing lip is provided with the inside of the inner ring.
The operation principle of this base case and have the beneficial effect that：When in use, bonded washer is enclosed within into drain valve spiral shell first
On bolt.Then, drain valve bolt and bonded washer are placed on liquid cold seat together, then tighten packing ring.This bonded washer
Under the effect of drain valve bolt pretightening, moderately deformed by the upper lower convex platform of inner ring, with drain valve bolt mounting plane and outer
Circle is concordant above, plays the effect of sealing.In addition inner ring seal lip shrink have holding to act on drain valve bolt, also function to compared with
Good sealing function.Drain valve bolt adds the sealing means of bonded washer, with single taper thread and O-ring sealing means phase
Than both having extended the service life of sealing ring, having also reduced cost.
Preferred version one：Based on scheme preferred version, the outer ring is made up of stainless steel material, and rustless steel can be prevented
Rust, corrosion resistance and good, because mechanism Chang Yushui contacts, easily get rusty, and can avoid getting rusty using stainless steel material.
Preferred version two：Preferably one preferred version, the inner ring is peroxide EP rubbers sealing ring, peroxide
EP rubbers has stronger resistance to ag(e)ing, and chemical stability is good, and service life is longer.
Preferred version three：Preferably two preferred version, the drain valve bolt is steel bolt, steel bolt
Intensity is high, long service life.
Description of the drawings
Fig. 1 is that a kind of new drain valve sealing structure of this utility model uses front structural representation；
Fig. 2 is structural representation when a kind of new drain valve sealing structure of this utility model is used；
Fig. 3 is the structural representation of bonded washer in a kind of new drain valve sealing structure of this utility model.
Specific embodiment
This utility model is described in further detail below by specific embodiment：
Reference in Figure of description includes：Liquid cold seat 10, outer ring 21, inner ring 22, annular projection 23, drain valve
Bolt 30.
Embodiment is substantially as shown in accompanying drawing 1, Fig. 2 and Fig. 3：A kind of new drain valve sealing structure, including liquid cold seat 10,
Drain valve bolt 30 and bonded washer, drain valve bolt 30 are coordinated with 10 screw thread of liquid cold seat, and bonded washer is located at liquid cold seat
Between 10 and drain valve bolt 30；Bonded washer includes inner ring 22 and outer ring 21.Inner ring height 0.6-1mm higher than outer ring.Outer ring
Annular projection 23 is provided with the inside of 21, the width of annular projection 23 is 0.5 ~ 1mm.Annular groove is provided with the outside of inner ring 22, annular is prominent
Rise 23 external diameters it is equal with annular groove internal diameter size, annular groove is embedded on annular projection 23；Sealing is provided with the inside of inner ring 22
Lip.Outer ring 21 is made up of stainless steel material, rustless steel energy antirust, corrosion resistance and good, because mechanism Chang Yushui contacts, easily
Get rusty, and can avoid getting rusty using stainless steel material.Inner ring 22 is peroxide EP rubbers sealing ring, and peroxide EP rubbers has
Stronger resistance to ag(e)ing, chemical stability are good, and service life is longer.Drain valve bolt 30 be steel bolt, steel bolt strength
Height, long service life.
When in use, first bonded washer is enclosed within drain valve bolt 30.Then, by drain valve bolt 30 and bonded washer
It is placed on together on liquid cold seat 10, now, the height of drain valve bolt to bonded washer is 16mm or so.Then tighten pad
Circle, this bonded washer are moderately deformed by the upper lower convex platform of inner ring 22, with drain valve under the effect of 30 pretightning force of drain valve bolt
30 mounting plane of bolt and outer ring 21 are concordant above, play the effect of sealing.In addition the height of drain valve bolt to bonded washer
For 15mm or so.22 seal lip of inner ring is shunk has holding to act on drain valve bolt 30, also functions to preferable sealing function.Let out
The sealing means of water valve bolt 30 plus bonded washer, compare with single taper thread with O-ring sealing means, have both extended sealing
The service life of circle, also reduces cost.
Above-described is only embodiment of the present utility model, the known general knowledge here such as concrete structure and characteristic in scheme
Excessive description is not made.It should be pointed out that for a person skilled in the art, in the premise without departing from this utility model structure
Under, some deformations and improvement can also be made, these should also be considered as protection domain of the present utility model, and these are all without impact
Effect and practical applicability that this utility model is implemented.This application claims protection domain should be with the content of its claim
It is defined, specific embodiment in description etc. records the content that can be used for explaining claim.
