Abstract
The invention discloses a novel wear-resistant fiber expansion joint, which comprises a left connecting pipe, a U-shaped expansion joint and a right connecting pipe. The U-shaped expansion joint is fixedly connected between the left connecting pipe and the right connecting pipe, a bidirectional guide pipe is further mounted in the U-shaped expansion joint and comprises a left guide pipe, a right guide pipe and a seal ring, the left end of the left guide pipe is fixedly and hermetically connected onto the left connecting pipe, the right end of the left guide pipe extends into the right guide pipe, the right end of the right guide pipe is fixedly and hermetically connected onto the right connecting pipe, and the seal ring is arranged between the left guide pipe and the right guide pipe and used for sealing a gap between the left guide pipe and the right guide pipe. Wear of the novel wear-resistant fiber expansion joint due to dust can be prevented, the service life of the novel wear-resistant fiber expansion joint is prolonged, and the novel wear-resistant fiber expansion joint is applicable to horizontal mounting of pipelines with large compensation quantity and is simple in mounting technology.
Description
Technical field
The present invention relates to a kind of expansion joint, particularly a kind of non-metal expansion joint.
Background technique
The filament expansion joint can provide bigger multidirectional compensation rate on less axial mounting distance; Can effectively eliminate simultaneously the installation integrating error of whole system; So extensively adopted; But the filament expansion joint often uses in the abominable fume ducts of environment, and dust causes the wearing and tearing of filament expansion joint easily in the pipeline, influences the working life of filament expansion joint.
Summary of the invention
Technical problem to be solved by this invention is the deficiency to above-mentioned existing technology, and a kind of filament expansion joint of anti-dust wearing and tearing is provided.
For solving the problems of the technologies described above, the technological scheme that the present invention adopted is: a kind of novel wear resistant filament expansion joint comprises left side adapter, U type expansion joint and right the adapter; Said U type expansion joint is fixedly connected between left side adapter and right the adapter, it is characterized in that: in the U type expansion joint bidirectional guide pipe is installed also; Said bidirectional guide pipe comprises left honeycomb duct, right honeycomb duct and seal ring; The left end of left side honeycomb duct is fixedly connected on a left side and takes over, and and a left side take between for being tightly connected, the right-hand member of left honeycomb duct stretches in the right honeycomb duct; The right-hand member of right honeycomb duct is fixedly connected on right the adapter, and and the right side take between for being tightly connected; Seal ring is arranged between left honeycomb duct and the right honeycomb duct, and seal ring is used for the space between left honeycomb duct and the right honeycomb duct is sealed up.
As the further improved technological scheme of the present invention, said U type expansion joint is connected between left side adapter and right the adapter through screw bolt and nut, is lined with steel plate between U type expansion joint and the bolt and between U type expansion joint and the nut.
As the further improved technological scheme of the present invention, between a nut and a left side are taken over, and be lined with sheet rubber between nut and right the adapter.
As the further improved technological scheme of the present invention, said sheet rubber is an ethylene propylene diene rubber.
The present invention is equipped with the bidirectional guide pipe in U type expansion joint outside; Seal with seal ring between the bidirectional guide pipe; Can prevent that ducted dust from touching U type expansion joint, cause wearing and tearing, prolong the working life of U type expansion joint greatly U type expansion joint; The present invention installs applicable to the king-sized pipe level of compensation rate, and mounting process is simple.
