Also disclosed is a novel material conveying pipe, which comprises two metal pipes with butt joints, wherein a flange is arranged at the mouth of the metal pipe, a plastic lining is arranged in the pipe, and the above protection device is also included. The two ends of the protection device are respectively extended into two metal pipes to form a shield for the inner wall of the metal pipe orifice, and the sealing gasket of the protection device is fitted with the flange surface for sealing. The utility model adds a special gasket to the flange port, so that the weak part of the port is strengthened, the special inclined surface flow channel opening of the protection device makes the medium moving flow channel smooth, and the problem that the flange port of the existing plastic-lined composite steel pipe is easily damaged is solved. Prevents failure or blockage of the line due to damage to the port lining.
Description
Technical field
The utility model belongs to craft piping technical field, and in particular to a kind of flange port protection of plastic lining metal tube
Device and novel conveying pipeline.
Background technique
Plastic lining composite steel tube is due to its intensity height, and temperature tolerance is good, than stainless steel low cost, therefore in chemical industry, chemical fertilizer
It is widely used in manufacturing, is mainly used for the conveying of sewage, corrosive media etc..But due to various reasons, often
Often there is the breakage of liner, once inner lining damage, corrosive media will directly contact outer layer carbon steel pipeline, cause whole root canal road
It scraps, while damaged liner deforms and is easy blocking pipeline, causes media flow unsmooth, causes strong influence to production, and
And inner lining damage or deformation blocking are not easy to be found in time.Removed pipeline inspection, discovery breaking point substantially all for flange into
At mouthful.Since import is washed away, import frictional force increases, causes change of flow state and cause plastic-lined strain drawing crack, split
After line, lining pulls deformation.
Utility model content
The purpose of this utility model is that in view of the above-mentioned problems, providing that a kind of suitable structure is simple, plastic lining easy to use
In metal tube flange port protective device and novel conveying pipeline.
For this purpose, the technology employed by the present utility model is
The main body of a kind of flange port protective device of plastic lining metal tube, the protective device is tube body, in the pipe
The middle part periphery of body is integrally outward extended with gasket, in the shape of a trumpet at two nozzles of tube body.
In the above-mentioned technical solutions, the gasket is vertical with tube body, so that the end of gasket and the metal tube to be connect
The flange of mouth, which fits, plays sealing function.
Preferably, the material of the protective device is polytetrafluoroethylene (PTFE), can be integrally formed by polytetrafluoroethylene material
Press process forms, and polytetrafluoroethylene material is integrally formed to be easy, ideal as gasket seal.
A kind of novel conveying pipeline is provided with flange at the nozzle of the metal tube including the metal tube that two root canal orifices dock,
It is equipped with plastic lining in pipe, further includes above-mentioned protective device, the both ends of the protective device are respectively protruding into two metal tubes,
To form the gear shield to metal tube internal wall of pipe orifice, the gasket of protective device is bonded with flange face to seal.
Preferably, the metal tube is composite steel tube, and composite steel tube source is wide, is easy to get, and corrosion resistance is strong, by force
Degree is high, and temperature tolerance is good, than stainless steel low cost.
The beneficial effects of the utility model are: the protective device of the utility model connected with by the protective device it is new
Type conveying pipeline enhances port weak part, special gradient runner mouth makes by increasing special gasket in flange port
Medium motion runner is smooth, solves the problems, such as that existing plastic lining composite steel tube flange port is easy to damage, prevents port liner
Damage causes scrapping or blocking for pipeline.The utility model is designed reasonably manufactures handling ease, and investment is small, easy for installation, makes to serve as a contrast
In damageable zone be effectively protected, extend the service life of Lined Pipeline.
Detailed description of the invention
Fig. 1 is the structural representation cross-sectional view of the protective device of the utility model.
Fig. 2 is the structural representation cross-sectional view of the novel conveying pipeline of the utility model.
Specific embodiment
By way of example and in conjunction with the accompanying drawings, the utility model is described in further detail:
The flange port protective device of 1 plastic lining metal tube of embodiment
A kind of flange port protective device of plastic lining metal tube as shown in Figure 1, the main body of protective device are tube body 1,
Integrally be outward extended with gasket 2 in the middle part periphery of tube body 1, at two nozzles of tube body 1 in horn mouth 1a shape gasket 2 with
Tube body 1 is vertical.Inner surface at two nozzles of tube body 1 is inclined-plane 1a.Protective device can by polytetrafluoroethylene material integral into
Type press process forms, and polytetrafluoroethylene material is integrally formed to be easy, ideal as gasket seal.
The novel conveying pipeline of embodiment 2
A kind of novel conveying pipeline as shown in Figure 2, mainly by the metal tube 3 of two root canal orifices docking and the protection of embodiment 1
Device composition.Metal tube 3 is composite steel tube, and flange 4 is provided at the nozzle of metal tube 3, is equipped with plastic lining 5 in pipe.Protection
The outer diameter of the tube body 1 of device is less than the internal diameter of metal tube 3, and the both ends of tube body 1 are respectively protruding into two metal tubes 3 to be formed to gold
Belong to the gear shield of pipe internal wall of pipe orifice, then two flanges are fixedly connected by bolt, the gasket 2 of protective device and 4 face of flange
Fitting seals.
The novel conveying pipeline of the utility model obtains port weak part by increasing special gasket in flange port
Enhancing, the special inclined flow path mouth of protective device keep medium motion runner smooth, solve existing plastic lining clad steel tube method
Blue port problem easy to damage prevents port liner damage from causing scrapping or blocking for pipeline.The utility model is designed reasonably, system
Handling ease is made, investment is small, and it is easy for installation, so that lining damageable zone is effectively protected, extends the service life of Lined Pipeline.
