Abstract
The utility model relates to a hydraulic change-over cut-off valve which is composed of hydraulic cylinders, rocker arms, a rotating shaft, a rotating pin, a valve plate, a valve body, etc., wherein two hydraulic cylinders are respectively fixed at both sides of the valve body. A sealing piece is fixed on the rotating shaft; baffle plates are fixed on the valve body; the sealing piece, the baffle plates and the edge of the valve body form into a sealing silo. An air inlet hole is arranged on the valve body positioned between two baffle pieces; a pointer can also be arranged on the rotating shaft. The structure largely simplifies a change-over regulation and cut-off device arranged in a pipeline; only one hydraulic change-over cut-off valve can simultaneously finish the change-over regulation and cut-off work of mediums in two pipelines; the flow rate of the mediums can be arbitrarily regulated through different rotating angles of the valve plate. The cost is reduced; the working performance of the product is enhanced.
Description
One. technical field
This novel control gear that can play adjusting commutation and partition that uses in a kind of conveyance conduit that relates to fed sheet of a media.
Two. background technique
Adopt isolated door that the medium in the conveyance conduit is controlled in the prior art, mainly be that isolated door is installed on the pipeline, the door-plate that adopts cylinder to promote on the isolated door moves the effect that reaches isolated medium, its structure is seen Fig. 1, two isolated doors 33 are housed respectively on two pipelines 22, the unlatching of a pipeline 22 of each isolated door 33 control is with closed, the cylinder 11 that is fixed on the body 55 promotes door-plate 44 motions, be characterized in that one isolated 33 can only be controlled a pipeline 22, control is for the flow direction of as shown in Figure 1 two-way control media, needing to install two isolated doors could realize, it takes up room greatly, because of isolated door only has two states of opening and closing, can't realize adjusting to rate-of flow.
Three. summary of the invention
This novel purpose is to provide a kind of novel commutation of surging to close door, with cigarette, wind and the gas of finishing fuel oil, combustion gas and the coal-burning power plant purpose at adjusting, commutation and the partition of different direction, and can realize the adjusting of rate-of flow.
This novel structure is as follows, by oil hydraulic cylinder, rocking arm, rotating shaft, ship and resell on another market, door-plate, Men Ti etc. form, wherein two oil hydraulic cylinders are separately fixed at the both sides of a body, rotating shaft is set on the body, two rocking arms are separately fixed at the two ends of rotating shaft, be fixed with door-plate in the rotating shaft, rocking arm is movably connected on the piston of oil hydraulic cylinder by shipping and reselling on another market; Also be fixed with diaphragm seal on the door-plate, door is fixed with baffle plate on the body, and gas-tight silo is formed at the edge of diaphragm seal and baffle plate and door body, has inlet hole on the body between two catch, also can be provided with pointer in the rotating shaft.
This structure, simplified greatly to be installed in and regulated commutation and partition apparatus in the pipeline, only need the commutation shutoff door that surges, just can finish the medium of two pipelines simultaneously and regulate commutation and partition work, and rate-of flow can be regulated arbitrarily by the different rotation angles of door-plate, reduce cost, improved the service behaviour of product.

Five. embodiment
This novel project organization as shown in Figure 2, by oil hydraulic cylinder 3, rocking arm 1, rotating shaft 2, ship and resell on another market 5, door-plate 4, door body 6 etc. form, wherein two oil hydraulic cylinders 3 are separately fixed at the both sides of a body 6, rotating shaft 2 is set on the body 6, and can on door body 6, rotate, door body 6 is the seal casinghousings that become by the steel plate assembly welding, and be connected with controlled pipeline 22 by flange, two rocking arms 1 are separately fixed at the two ends of rotating shaft 2, be fixed with door-plate 4 in the rotating shaft 2, rocking arm 15 is movably connected on the piston of oil hydraulic cylinder 3 by shipping and reselling on another market; Also be fixed with diaphragm seal 7 on the door-plate 4, be fixed with baffle plate 11 on the door body 6, and have inlet hole 8, the pointer 9 of indication door-plate 4 angle of swing also is housed in the rotating shaft 2, on the door body 6 dial 10 is housed, with the angle of display pointer 9 rotations.
(concrete control procedure is not in this patent scope by the piston stroke on the control oil hydraulic cylinder 3 during work, so do not describe in detail), driving rocking arm 1 by piston is that rotate in the axle center with rotating shaft 2, thereby again since rocking arm 1 be fixed in the rotating shaft 2 and drive rotating shaft 2 and rotate together, also be fixed with door-plate 4 in the rotating shaft 2, this moment, door-plate 4 also rotated with rotating shaft 2, door-plate 4 has forwarded the B pipe to as shown in Figure 6, thereby closed the flow direction of the A → B of pipeline 22, medium can only be moved along the pipeline of A → C, door-plate 4 shown in Figure 7 has forwarded the C pipe to, has closed the flow direction of the A → C of pipeline 22, and medium can only be moved along the pipeline of A → B, door-plate 4 forwards the neutral position of a body 6 to as shown in Figure 8, the α angle can be regulated arbitrarily with the different displacement amounts of piston in oil hydraulic cylinder 3, by regulating different α angles, plays the different flow of control media in pipeline B and pipeline C.
On door-plate 6, also be fixed with elastic metallic diaphragm seal 7, on door body 6, also be fixed with baffle plate 11, on the door body 6 between two baffle plates, have inlet hole 8, diaphragm seal 7 cooperates with baffle plate 11 when making door-plate 6 close pipeline 22, diaphragm seal 7, baffle plate 11 form gas-tight silo 12 with the edge of door-plate 4, pressurized air T enters into gas-tight silo 12 by inlet hole 8, keeps diaphragm seal 7 to contact with the tight of baffle plate 11 by air pressure, thereby reaches sealing effect.
Pointer 9 also is housed in rotating shaft 2,, thereby can indicates the angle of swing of door-plate 4 because pointer 9 is fixed in the rotating shaft 2.
