Description
Technical field：
The utility model is related to machine encapsulation technique fields, are specially a kind of Novel machine envelope.
Background technology：
Machine seals, full name mechanical seal, and in industry common people's custom is known as machine envelope.It is it is a kind of be used for solving rotation axis with
The device sealed between body.By it is at least a pair of perpendicular to the end face of rotation axis Fluid pressure and compensation mechanism elastic force (or
Magnetic force) effect and auxiliary seal cooperation under keep be bonded and formed with respect to slip prevent fluid leak device, commonly use
In rotary type fluid machines such as pump, compressor, reaction stirred tanks, gear-box, valve, rotary joint, marine rear shaft etc. are also used for
Sealing.Therefore, mechanical seal is a kind of general gland seal device.
In the prior art, machine seals up restrictor ring and throat bushing gap is bigger than normal, and structure type causes machine sealing chamber pressure less than Jie
Matter pressure, machine are enclosed in unclean environment and run, and service life is short.
Utility model content：
The purpose of this utility model is to provide a kind of Novel machine envelope, to solve the problems mentioned in the above background technology.
To achieve the above object, the utility model is implemented by following technical solution：A kind of Novel machine envelope, including sealing body, institute
It states envelope intracoelomic cavity and machine sealing chamber is set, the machine sealing chamber one side is equipped with the restrictor ring and throat bushing to cooperate；The restrictor ring bag
Ring body is included, the outer wall of the ring body is equipped with helicla flute, and the ring body inner cavity is equipped with straight slot, is set below the straight slot
Stirrup, the straight slot connection throttling through hole；The throat bushing includes cylinder, and the outside of the cylinder is equipped with and the spiral
The matched external screw thread of slot, the inside of the cylinder are axially provided with throttle orifice, and the throttle orifice is stepped hole and aperture is big
One end be interior hexagonal structure.
Further, the throttling through hole is circular configuration.
Further, the restrictor ring and the throat bushing are made of 304 stainless steels.
Further, the ring body and the cylinder outer rim are rounded corner.
Further, the stirrup is conical structure.
The advantages of the utility model：Overall structure is simple, will be in machine sealing chamber by the cooperation of novel throttling ring and throat bushing
Flushing water discharge pressure raises, and WATER AS FLOW MEDIUM is prevented to enter machine sealing chamber, so as to improve the service life of machine envelope；Its is simple in structure, into
This economy, effect protrude, and original structure machine envelope most long service life 45 days, continuous operating time is most 90 days short after transformation.
Description of the drawings：
Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is the utility model restrictor ring sectional view.
Fig. 3 is the utility model throat bushing sectional view.
The mark of each component is as follows in attached drawing：Seal body 1, machine sealing chamber 2, restrictor ring 3, throat bushing 4, ring body 5, helicla flute 6,
Straight slot 7, stirrup 8, throttling through hole 9, cylinder 10, external screw thread 11, throttle orifice 12.
Specific embodiment：
Below in conjunction with attached drawing, by embodiment, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of Novel machine envelope, including sealing body 1,1 inner cavity of envelope body sets machine sealing chamber 2, machine sealing chamber 2 one
Side is equipped with the restrictor ring 3 to cooperate and throat bushing 4, restrictor ring 3 and throat bushing 4 are made of 304 stainless steels, can prevented
It gets rusty after long-time service under rugged environment, extends its service life.
Restrictor ring 3 includes ring body 5, and the outer wall of ring body 5 is equipped with helicla flute 6, and 5 inner cavity of ring body is equipped with straight slot 7, leads to
7 lower section of slot sets stirrup 8, and stirrup 8 is conical structure；The connection throttling through hole 9 of straight slot 7, throttling through hole 9 is circular configuration.
Throat bushing 4 includes cylinder 10, and the outside of cylinder 10 is equipped with and 6 matched external screw thread 11 of helicla flute, cylinder
The inside of body 10 is axially provided with throttle orifice 12, and throttle orifice 12 is that the big one end of stepped hole and aperture is interior hexagonal structure；Ring sheet
Body 5 and 10 outer rim of cylinder are rounded corner.
In use, pump rotates in an anti-clockwise direction, restrictor ring 3 is rotated with pump, and helicla flute 6 coordinates with throat bushing 4 will be in chamber
Flushing water boosts, and pressure is higher than medium water pressure, realizes the clean purpose rinsed in chamber.
The utility model overall structure is simple, by the cooperation of novel throttling ring 3 and throat bushing 4, will be rinsed in machine sealing chamber 2
Water discharge pressure raises, and WATER AS FLOW MEDIUM is prevented to enter machine sealing chamber 2, so as to improve the service life of machine envelope；Its is simple in structure, cost warp
Ji, effect protrude, and original structure machine envelope most long service life 45 days, continuous operating time is most 90 days short after transformation.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modifications, equivalent replacements and improvements are made should be included in the utility model
Protection domain within.
