Embodiment
Elaborate to the utility model below by embodiment, described embodiment is illustrative, and nonrestrictive, can not limit protection domain of the present utility model with this.
A kind of energy-saving hydraulic slow-closing type rollover flap valve, comprise valve body, rollover door described valve body one side end is arranged on drainage pipe discharge ends by bolt 9 and flange plate is connected with described drainage pipe, the end side of this valve body is shaped with drain opening 8, these drain opening both sides are hinged with described rollover door respectively by hinge 5 and hinge 6, this both sides overhead door is relatively made and described drain opening can be closed, the drain opening front end that described valve body is made is shaped with described Stamping Steel Ribbon, the utility model innovation is, the upper and lower both sides of drain opening that described valve body is made are shaped with multiple cushion cylinder 2 respectively, multiple Slow Close block 3 is shaped with respectively with the upper and lower two ends of rollover door of the piston rod end phase contraposition of making in described cushion cylinder, when in rollover door closing process, described multiple Slow Close block can be crimped on the oil extraction process that piston rod end that phase contraposition makes completes cushion cylinder.
In the present embodiment, due to dislocation offset problem that unbalance stress causes in piston rod and Slow Close block contact process, described multiple cushion cylinder is made along valve body drain opening bearing of trend is parallel, and the piston rod end of making in described cushion cylinder is stretched out by the front end of described drain opening.The piston rod end of making in described cushion cylinder is shaped with hemispherical bumps 12, in the Slow Close block end face made with the homonymy contraposition of described piston rod end, be shaped with the groove 11 with described hemispherical bumps tabling.
In the present embodiment, in order to improve the rigidity of described Slow Close block and cushion cylinder, described Slow Close block is integrally shaped with fixed end and leans out end, described fixed end is fixedly mounted with mutually with end face in front of the door of turning on one's side, the described end that leans out is stretched out made with the contraposition of described piston rod end by rollover door edge, described in lean out end front-end face in be shaped with the integrally formed reinforcement block 7 with fixed end respectively.Be shaped with installation sleeve 13 respectively in the outer rim end face of described valve body upper and lower both sides, the front end of the described cushion cylinder of suit in described installation sleeve, the rearward end of this cushion cylinder to be inlaid in limiting stopper that described valve body outer rim end face makes 14.
Using process of the present utility model is:
When the utility model uses, by the differential water pressures that rollover door both sides are different, the opening and closing of both sides overhead door can be controlled without the need to applying external force, thus control conducting or the closedown of waste pipe, because the end of piston rod is stretched out by the front end of drain opening, therefore when door of turning on one's side is closed, the groove made in the hemispherical bumps that piston rod front end is made and Slow Close block is prior to the contact of turn on one's side door and Stamping Steel Ribbon, when Slow Close block is crimped on the end of piston rod, Slow Close piston carries out oil extraction process, offside overhead door applies a reverse active force, thus the closing process of offside overhead door slows down, until rollover door is completely closed, when door of turning on one's side is opened, after rollover Men Yuhuan compressing cylinder end separating, slow compressing cylinder carries out Oil feeding process, until rollover next time door carries out reciprocal closing process.
In the utility model, valve body, rollover door and Stamping Steel Ribbon match and can be used for controlling the opening encapsulation of outlet pipe, wherein cushion cylinder coordinates Slow Close block that rollover door can be made when closing, the contact of piston rod is made in Slow Close block and cushion cylinder, prior to the contact of turn on one's side door and Stamping Steel Ribbon, thus by the active force on the oil extraction process release rollover door of cushion cylinder; The hemispherical bumps that the groove fit piston rod end of making in Slow Close block is made can avoid the dislocation caused due to unbalance stress in piston rod and Slow Close block contact process to offset, thus make piston rod contraposition be inlaid in groove, and then avoid Stamping Steel Ribbon and valve body is stressed deforms, improve the working life of device, the installation sleeve made in valve body outer rim end face coordinates limiting stopper, and Slow Close block leans out the structural rigidity that the reinforcement block holding front-end face to make can strengthen cushion cylinder and Slow Close block, improves the working life of rollover door further.
