Description
Technical field
Pipeline ball collecting chamber crash cushions relates to the crashproof damping device of pipeline ball collecting chamber that a kind of oil and gas pipeline transports.
Technical background
Pipeline transport is the best means of transportation of petroleum gas resource.In service at oil and gas pipes, the regular pigging of pipeline and in detect the guarantee that operation is the pipe safety operation.Wiper or detector are when entering ball collecting chamber, and owing to reasons such as effect of inertia, technological process and ball collecting chamber self designs, wiper or detector very easily clash into ball collecting chamber blind plate situation, cause the blind plate distortion easily.Serious even cause blind plate to break, have an accident.
Traditional solution is to place crashproof tire or rubber ball in ball collecting chamber, but still has following problem.
When technological process is switched to receipts ball flow process, because all gas flows out from the less bypass tube of bore, cause by-pass port place moment flow velocity to become big, add that crashproof tire very easily is offset at gas effect upper/lower positions, as long as tire has the part tyre surface to be arrived the bypass mouth of pipe by gas absorption, because the effect that tyre surface dams, whole tire will be dead with whole bypass mouth of pipe retaining gradually, and the phenomenon that whole tire is sucked into bypass tube takes place at last.
If use the rubber ball, owing to can't guarantee whether the blend stop at bypass tube place is complete, if threeway place blend stop is lost, the sphere that ball also can take place blocks bypass, in case the bypass mouth of pipe is kept off extremely, also the phenomenon that the rubber ball is sucked into bypass tube can take place.
In sum, use tire or rubber ball as preventing that from there is very big hidden danger in the method that wiper and detector impact blind plate, and along with the increase of pipeline working time and the increase of time of pigging, this hidden danger is also in continuous increase.In case have an accident, will cause tremendous loss to unit of operation and environment, therefore must take effective measures and overcome these hidden danger.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists at above-mentioned prior art, provides a kind of wiper and detector of effectively preventing to impact the pipeline ball collecting chamber crash cushions of blind plate, assurance pipeline security of operation, elimination operation and environment hidden danger.
Pipeline ball collecting chamber crash cushions is characterized in that its structure comprises:
Flange plate at the bottom of the bounce cylinder-this flange plate is a circular metal dish, the circumferential uniform bolt hole that has on the card of the limit of flange plate portion; On the card of portion in the flange plate, circumferentially be laid with circular groove;

Damper piston-this damper piston by a circular valve plate that is positioned at cylinder block with vertical with valve plate affixed and pass the valve rod of cylinder block termination shrouding stem through-hole and be arranged on the circular valve plate edge and the cylinder block inwall between a seal ring form;
Before anti-raming-this anti-raming is the polyurethane discs body that an external diameter cooperates with the oil and gas pipes inwall, have the bolt hole corresponding on the disc with flange plate at the bottom of the cylinder, flange plate is affixed at the bottom of preceding prevent raming fixing bolt by passing bolt hole and the bounce cylinder;
Rear anti-crash head flange dish-this flange plate is a circular metal dish, is fixedly connected with the bounce cylinder stem head;
Rear defence rams-and this anti-raming is the polyurethane discs body that an external diameter cooperates with the oil and gas pipes inwall, and rear defence is ramed affixed by fixing bolt and rear anti-crash head flange dish.
Pipeline ball collecting chamber crash cushions of the present utility model, it is characterized in that described bounce cylinder be three or more than, and be provided with the oil and gas pipes axisymmetric.
Pipeline ball collecting chamber crash cushions of the present utility model, it is characterized in that cushioning institute's cylinder block root be provided with air outlet hole.
Pipeline ball collecting chamber crash cushions of the present utility model, is the hidden danger that exists at using tire or rubber ball as the method that prevents wiper and detector impact blind plate, a kind of cushion effect device that adopts the cylinder pressurized gas to produce is provided, has prevented that effectively wiper and detector from impacting blind plate, guarantee the pipeline security of operation, eliminating operation and environment hidden danger.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Pipeline ball collecting chamber crash cushions, its structure comprises:
Flange plate 1 at the bottom of the bounce cylinder-this flange plate is a circular metal dish, the circumferential uniform bolt hole that has on the card of the limit of flange plate portion; On the card of portion in the flange plate, circumferentially be laid with circular groove;
Bounce cylinder 2-this cylinder body is a cylindrical tube, and a termination of its cylindrical shell embeds at the bottom of the cylinder in the flange plate circular groove, by be fixed in flange ring on the cylindrical shell outer by screw on flange plate at the bottom of the cylinder; Another termination of its cylindrical shell be provided with one with the shrouding 3 of cylinder block axis normal, have a stem through-hole on its shrouding between two parties;
Damper piston 4-this damper piston by a circular valve plate 5 that is positioned at cylinder block with vertical with valve plate affixed and pass the valve rod 6 of cylinder block termination shrouding stem through-hole and be arranged on the circular valve plate edge and the cylinder block inwall between a seal ring 7 form;
Before anti-8-this anti-the raming of raming is the polyurethane discs body that an external diameter cooperates with the oil and gas pipes inwall, have the bolt hole corresponding on the disc with flange plate at the bottom of the cylinder, flange plate is affixed at the bottom of preceding prevent raming fixing bolt 9 by passing bolt hole and the bounce cylinder;
Rear anti-crash head flange dish 10-this flange plate is a circular metal dish, is fixedly connected with the bounce cylinder stem head;
Rear defence rams 11-and this anti-raming is the polyurethane discs body that an external diameter cooperates with the oil and gas pipes inwall, and rear defence is ramed affixed by fixing bolt 12 and rear anti-crash head flange dish.
Pipeline ball collecting chamber crash cushions of the present utility model, described bounce cylinder be one or more than, and be provided with the oil and gas pipes axisymmetric.Described buffering institute cylinder cylinder body root be provided with air outlet hole 13.
During operation, after wiper or detector rush at buffer, at first touching back polyurethane prevents raming, anti-the raming of back polyurethane moves forward, and the piston rod that is attached thereto by the rear stub drive moves forward together, because the seal action of seal ring is arranged, when in piston cylinder, continuing to move forward, gas in the bounce cylinder is compressed, and just produces reaction thrust at valve rod like this, along with the continuous compression of gas, reaction thrust also constantly increases, this reaction thrust affacts on wiper or the detector, has just slowed down its impact force greatly, has avoided the destruction that ball collecting chamber is produced.In addition, since the bounce cylinder root be provided with very little air outlet hole when wiper or detector by after buffering stops fully, the pressurized gas in the bounce cylinder is slow release just, until equal with the piston cylinder pressure outside, when we opened ball collecting chamber, anti-the raming of preceding polyurethane just do not have rebounding force like this.In the middle of two polyurethane are prevented raming the gas compression cylinder is housed, according to ball collecting chamber bore difference, compression cylinder length is between the 400-1500 millimeter, and the compression cylinder diameter is between Φ 60-Φ 800, and the air outlet hole diameter is between Φ 0.5-Φ 8.
