    • 专利摘要:
    Apparatus for cleaning straight or arcuate conduits has a housing which fits with clearance into a conduit and has an elastic washer slidably engaging the internal surface of the conduit so that the pressure of a fluid which fills the conduit behind the housing propels the housing forwardly until the housing encounters an incrustation or another obstruction. The housing contains a reciprocable impeller which can strike against the housing under the action of a spring to thereby cause a set of cutting tools at the exterior of the housing and in front of the washer to break up or strip off the obstruction. The impeller is cocked by a hollow plunger which has a flow-restricting end wall for admission of pressurized fluid into the internal space of the housing and moves rearwardly when the internal space is free to communicate with the conduit portion ahead of the housing by way of outlet openings which are provided in the housing and are normally sealed by a reciprocable valve which is biased to its operative position by a spring.

    专利说明:

    The invention relates to the cleaning of the inner surfaces of the channels, and in particular to devices with reciprocating motion pushed by the action of a liquid.
    A percussion device for cleaning industrial pipelines with flushing fluid is known, comprising a cylindrical body with outlet openings, a sealing collar and a cutting head located on it, a distributor valve and a fluid injection system fl} located in the housing.
    The disadvantage of this device is the loss of water hammer in case of a loose fit of the treatment device in the pipeline as a result of this reduction in cleaning efficiency.
    The purpose of the invention is improving the efficiency of cleaning industrial pipelines and> ensuring reliability. 25
    This goal is achieved in that the device comprising a cylindrical body with outlet openings, a sealing collar and a cutting head located on it, a distributor valve and a fluid injection system located in the housing, has a ball lock and a spring-loaded shock and spring loaded in the body of the concentrically distributed valve hollow platoon pistons with throttling openings in the end of the latter and in its middle part, the impact piston being connected to the distributor with a spool and cocking piston by means of a ball lock. In addition, the shock piston has holes on the side surface, the inner surface of the spool valve and the outer surface of the cocking piston have annular grooves, and the ball lock balls are located in the holes of the shock piston.
    The cocking piston has a differential part, and the annular cavity formed by its differential part and the inner surface of the housing is in communication with a pipeline cavity located in front of the device in the direction of its movement.
    In FIG. 1 shows the proposed device, a section; in FIG. 2 - the same, with the shock piston laid back.
    The device for cleaning pipelines has a cutting head 1, a cylindrical body 2 with exhaust holes 3, a sealing collar 4, a spool 5, a fluid injection system (not shown), a ball lock 6 with balls 7, placed in a body concentric with a spool with a spring 8 shock piston 9, a hollow cocking piston 10 with a spring 11 and with a throttle bore 12 made at its end, and in its middle part - bypass holes 13, the end surface 14 of the cocking piston facing the shock piston 14 The shock piston is connected to the cocking piston by means of a ball lock, wherein the shock piston has holes 05 on the side surface, and the inner surface of the spool valve and the outer surface of the cocking piston have ring grooves 16 and 17. Ball lock balls are located in the ring holes 18 of the shock piston.
    In addition, the cocking piston has a differential part 19, and the annular cavity 20 formed by its differential part and the inner surface of the housing is connected to a pipe cavity located in front of the device in the direction of its movement.
    The operation of the device is as follows.
    The device moves in the pipeline under the influence of pressure medium. When the cutter head 1 encounters resistance, the fluid pressure inside the device increases, which acts on the end surface 14 of the plunger 10 and moves it together with the shock piston 9. The plunger piston is connected via a ball lock 6 to the shock piston, while the spring 11 is tensioned. The spring 8 is tensioned. When the ball lock 6 is aligned with the annular grooves 18, the spool 5 is connected to the shock piston 9, which moves in the direction of the cutting head 1, making an impact on it. In the process of moving the spool 5, the outlet 3 opens. Since the hole 12 is a throttling one, the plunger piston 10, under the action of the pressure medium in the rear part of the pipeline, moves towards the cutter head, compressing the spring 11. As soon as the annular groove 17 of the plunger piston 10 is connected to the ball lock
    6, spool 5 under the action of a spring. 8 will move to its original position, then the outlet 3 is locked.
    If the resistance in front of the cutting head is not eliminated, the process is repeated.
    The proposed device is technologically advanced in manufacture and can be used to clean straight and curved pipelines. During operation it does not require additional energy consumption, since the energy of the flowing medium is used as a working fluid.

    The pipeline cleaning device has a cutting head 1, a cylindrical body 2 with outlets 3, a sealing lip 4, a distribution spool 5, a fluid injection system (not shown), a ball lock 6 with balls 7 placed in the housing concentrically to the distribution spool with spring 8 percussion piston 9, hollow platoon piston 10 with spring 11 and with a throttle bore 12 at its end, and in its middle part with bypass bores 13 reversed to a percussion piston end surface 14 of a platoon piston. The shock piston is connected to the platoon piston by means of a ball lock, wherein the impact piston has openings Q5 on the side surface, and the inner surface of the distribution spool and the outer surface of the piston piston have annular grooves 16 and 17. The balls of the ball lock are placed in the annular bore x 18 shock piston. In addition, the platoon piston has a differential part 19, and the annular cavity 20 formed by its differential part and the inner surface of the housing is connected to the cavity pipe located in front of the device during its movement. The operation of the device is as follows. The device moves in the pipeline under the influence of pressure medium. When the tool head 1 encounters resistance, inside the device, the fluid pressure increases, which acts on the end surface 14 of the control piston 10 and moves it together with the impact piston 9. The power piston is connected by means of a ball lock 6 with the impact piston, while the spring 1 . Tensioning of the spring 8 occurs. When the ball lock 6 is aligned with the annular grooves 18, the connection of the spool 5 to the impact piston 9, which moves in the direction of the tool head 1, produces a blow. During the movement of the spool 5, the outlets 3 are opened. Since the hole 12 is throttling, the platoon piston 10 under the action of the pressure medium in the rear part of the pipeline moves towards the cutting head, compressing the spring 11. As the only ring groove 17 of the platoon piston 10 is connected to the ball lock 6, the spool 5 is under the action of the spring. 8 will move to its original position, then the outlets 3 will be blocked. If the resistance in front of the cutter head is not eliminated, the process is repeated. The proposed device is easy to manufacture and can be used to clean straight and curved pipelines. During operation, it does not require additional energy consumption, since the energy of the flowing medium is used as the working medium. Claim 1.
