Abstract
The invention discloses a sealing device for a tube stock vacuum calibration box and belongs to the technical field of accessory equipment for steel-plastic composite pressure tube stock manufacturing. The sealing device is arranged at the end of the box body of the vacuum calibration box and is characterized by comprising a double-layer flange plate fixedly connected with the box body, a liquid storage groove is formed in the connecting position of the double-layer flange plate, and the box body of the vacuum calibration box is of a frameless oil sealing structure formed by oil liquid in the liquid storage groove. A frameless oil seal is used as a sealing ring, the characteristic of high sealing performance of the frameless oil seal is utilized, and firm installation of the oil seal is ensured and remodeling and detachment can be achieved easily through the standard dimension design of the frameless oil seal and the arrangement of a device connected with the vacuum box.
Description
Technical field
The invention belongs to steel-plastic composite pressure pipe material manufacture auxiliary device technical field, relate to a kind of pipe
The sealing structure of material vacuum sizing box, a kind of tubing using exoskeletal liquid seal is true
Empty sizing tank seals structure.
Background technology
Steel-plastic composite pressure pipe industry is a kind of new industry just grown up recent years, due to
This tubing is all to mould layer inside and outside one, and centre is argon arc Grith-Buttweled pipe, between steel pipe and plastics by
Special-purpose adhesive carries out bonding five layer composite pipe, makes this tubing possess bearing capacity height, price
Low, linear expansion coefficient is little, impact resistance is strong, good insulation preformance, inner wall smooth, length in service life etc.
Feature, is had an optimistic view of by numerous manufacturing firms and user.
In steel-plastic composite pressure pipe material production process, steel plastic compount is a kind of technical barrier, at compound sticking
During, the effect that play key bonding to steel plastic compount of the size of internal plastic tube outside dimension.At present
The common Rubber washer band differential sealing means used causes after abrasion owing to resistance is big, in production process
Vacuum is unstable, thus causes internal plastic tube size suddenly big or suddenly small, therefore design one good sealing effect,
Vacuum sealing device easy for installation is particularly important.
Summary of the invention
The present invention is to solve the problems referred to above, devise the sealing device of a kind of tubing vacuum sizing box,
Ensure that internal plastic tube material dimensionally stable, easy accessibility when remodeling.
The technical solution used in the present invention is: the sealing device of a kind of tubing vacuum sizing box, this sealing
Device is arranged at vacuum sizing box casing end, it is critical only that: described sealing device includes and case
Body fixes the Double-layer flange dish of connection, and the junction of Double-layer flange dish is provided with liquid storage groove, and vacuum is fixed
The casing of footpath case forms exoskeletal liquid sealing structure by the liquid in liquid storage groove.
The diameter of described liquid storage groove with the ratio of the diameter of the disk hole of Double-layer flange dish is
(1.2-1.5):1。
The 1/2 of the degree of depth of described liquid storage groove is equal to the 1/4 of the thickness of Double-layer flange dish.
4-8 fixing hole of even circumferential distribution it is provided with on described Double-layer flange dish.
The beneficial effects of the present invention is: this device uses oil seal without framework to be sealing ring, utilizes bone free
The feature of the good seal performance of frame oil sealing, is connected with vacuum tank according to standard oil seal without framework size design
Device, it is ensured that oil sealing is firmly installed, and is beneficial to dismounting of remodeling.
Accompanying drawing explanation
Fig. 1 is the top view of the present invention.
Fig. 2 is that the A-A of the present invention is to profile.
In accompanying drawing, 1 is Double-layer flange dish, and 2 is liquid storage groove, and 3 is disk hole, and 4 is fixing hole.
Detailed description of the invention
Seeing accompanying drawing 1, the sealing device of a kind of tubing vacuum sizing box, this sealing device is arranged at vacuum
Sizing tank casing end, described sealing device includes fixing the Double-layer flange dish 1 being connected with casing,
It is provided with 4-8 the fixing hole 4 of even circumferential distribution on described Double-layer flange dish 1, specifically can adopt
With 6.Double-layer flange dish 1 is provided with groove on two split flange surfaces, by two points
Body flange combination is to form liquid storage groove 2, and sealing oil seal without framework is fixed on two rustless steel split methods
In blue groove.Tubing enters in vacuum sizing box through the disk hole 3 of Double-layer flange dish 1, during entrance,
Tube surfaces is sealed the sealing realizing vacuum sizing box by oil seal without framework.Wherein, in order to realize more
The diameter of good sealing effectiveness, the diameter of described liquid storage groove 2 and the disk hole 3 of Double-layer flange dish 1
Ratio be (1.2-1.5): 1.The 1/2 of the degree of depth of described oil storage grooves 2 is equal to Double-layer flange dish
The 1/4 of the thickness of 1.
The present invention utilizes oil seal without framework to be sealing ring, rustless steel split flange is fixing device, solves
Resistance owing to using conventional seals device to cause is big, seal failure after leather packing abrasion, vacuum are unstable,
The internal plastic tube change in size phenomenon such as not.Use this sealing device that the process of internal plastic tube can be made the most steady
Fixed thus ensure that internal plastic tube with the fit clearance of steel pipe in reasonable bonding scope, improve steel and mould
Composite pressure tube steel is moulded bonding stability, is decreased the pipe material inner wall caused due to size shakiness and bubble
Phenomenon.
