A kind of vibration damping equipment for underground petroleum pipe joint of the present invention is by the following technical solutions:
A kind of vibration damping equipment for underground petroleum pipe joint, mainly comprise pipeline, locking nut, seal ring, vibration damper and connecting tube, pipeline is divided into pipeline A and pipeline B, locking nut is divided into locking nut A and locking nut B, seal ring is divided into seal ring A and seal ring B, what locking nut A, seal ring A, vibration damper, seal ring B, locking nut B were arranged on pipeline A and pipeline B successively is threaded in district, and vibration damper is welded on connecting tube; The interface section of described pipeline A and pipeline B is provided with outside thread, and locking nut A and locking nut B, seal ring A and seal ring B are provided with internal thread; Described vibration damper is 8 on single pipeline and circumference is uniform, vibration damper forms primarily of piston cylinder, piston block and spring, one end of piston block is provided with screw thread, it is for being arranged on pipeline A and pipeline B, the other end of piston block is connected with the spring in piston cylinder, spring leaves pre compressed magnitude, and the outer side wall of piston cylinder has exhaust port.
The present invention is respectively equipped with screw thread on pipeline A and pipeline B, locking nut A and locking nut B, seal ring A and seal ring B and piston block, by this structural design, there is following functions: one is be convenient to install fix, as only seal ring A rotated on pipeline A and can be installed, in addition, owing to being be threaded, moving radially of seal ring A can be prevented; Two is sealings of reinforced company's fitting, and the close contact be namely threaded connection realizes the sealing of surface of contact; Three is the gap adjustment being convenient to each link, as being applied to the pretightening force on seal ring A and the gap between them by rotational lock nut A adjustable, preventing because seal ring occurs gap and causing leakage.
The present invention is provided with seal ring A and seal ring B being threaded in district, is realized the double seal of mouth of pipe joint, namely prevent foreign matter from entering in pipeline by seal ring A, prevent fluids within pipes from leaking by seal ring B by this design.
The present invention is provided with locking nut A and locking nut B being threaded in district, by this design, there is following functions: one is prevent moving axially of link, namely by locking nut A and locking nut B, seal ring A, seal ring B and vibration damper is limited to fixed area; Two is close sealing, is adjusted gap and the pretightening force of each link when namely working by rotational lock nut A, and anti-fluid is leaked.
The present invention B on pipeline A and pipeline installs the vibration damper be made up of piston cylinder, piston block and spring respectively, and be that 8 circumferences are uniform, the radial vibration of pipeline can be eliminated by this design, namely as upper and lower vibration occurs pipeline A, when pipeline A moves, because upper end piston block is threaded connection on pipeline A, then pipeline A drive piston block together on move, leave the spring second compression again of pre compressed magnitude, thus the kinetic energy of pipeline A and piston block is converted to elastic potential energy, absorb kinetic energy, isolation energy transferring, eliminate the vibration of upper end connecting tube and pipeline B; And lower end piston block will drive the spring elongates leaving pre compressed magnitude, same realization will change vibrational energy, isolation energy transferring, eliminate the vibration of lower end connecting tube and pipeline B.
The present invention has exhaust port on piston cylinder, reduced the resistance to motion of piston block by this design, namely when piston block is to when moving away from piston cylinder direction, supplement piston cylinder internal air pressure in time by exhaust port, prevent from producing back pressure in piston cylinder, impede motion is produced to piston block; And when piston block moves to piston cylinder direction, excessive air pressure in piston cylinder can be discharged by exhaust port, hinder it to move when preventing piston block from moving down because of pressurized air.
The invention has the beneficial effects as follows: by the screw thread on pipeline, locking nut, seal ring and piston block, realize being convenient to installing sealing and the gap adjustment of fixing, reinforced company's fitting; Isolation impurity and the leakage of anti-fluid is realized by double-sealing design; Realize preventing moving axially and closing sealing of link by locking nut; The radial vibration eliminating pipeline is realized by the vibration damper that 8 circumferences are uniform.
