Technical field
The utility model relates to a kind of on-off valve device, relates in particular to a kind of pumping board valve.
Background technique
Be extensive use of medium-speed pulverizer in existing thermal power generation corporations, demand medium speed grinding stone coal discharging recovery plant needs the stone coal channel is carried out switch control in these equipment.Because the medium speed grinding working environment is to carry out, sealing, resistance to pressure and the protection against dust of this channel valve all there is certain requirement under higher temperature and elevated pressures.Existing pumping board valve, just simply move up and down and cut off that channel seal is very poor, slideway stops up easily with valve plate, often cause the container inner pressure loss and make a lot of energy wastes, and the structural design of existing pumping board valve is reasonable inadequately, do not have auto-lock function and damage easily.
Summary of the invention
The utility model is at the existing in prior technology shortcoming, and provides a kind of simple in structure, the technological scheme of good airproof performance, long service life and pumping board valve that have auto-lock function.
The utility model is realized by following technical measures: a kind of pumping board valve, it comprises valve plate, described valve plate is between upper and lower valve port, described valve plate cooperates with valve port to be realized cutting off and conducting, described valve plate is fixedly mounted in the valve plate sealing bow folder of its both sides, the both sides correspondence of described upper and lower valve port is installed in described valve plate and the valve plate sealing is bent between the folder, and described valve plate sealing bow folder can cooperate the locking and positioning of cut-out and two states of conducting with valve port.
Concrete characteristics of the present utility model also have, above-mentioned valve plate sealing bow folder comprises two shaped as frame structural members that are fixed together, slotted hole in the middle of each shaped as frame structural member is is mainly connected and composed by rectangular hole and trapezoidal hole, described two shaped as frame structural members are provided with an end positioned opposite of trapezoidal hole, and the trapezoidal hole on the described shaped as frame structural member cooperates the locking and positioning of realizing cut-out and two states of conducting with the wedge-shaped structure of the both sides of valve port.
The drive end of above-mentioned valve plate is fixedlyed connected with the piston rod overhanging end of oil hydraulic cylinder.
Above-mentioned valve plate and valve plate sealing bow folder are outside equipped with encapsulation, and described encapsulation is fixedlyed connected with valve port.
Further improvement of the utility model also has, be positioned on the outer wall of free-ended upper and lower valve port of described valve plate the pushing off the slag slide block is installed, described pushing off the slag slide block set is contained on the guide blot, be set with Returnning spring on the guide blot, described Returnning spring is between the spiral shell head of pushing off the slag slide block and guide blot, and the threaded end of described guide blot is fixedlyed connected with the outer wall of upper and lower valve port.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because the pumping board valve is provided with auto-lock function, this can guarantee that the pumping board valve is positioned at conducting and two states of cut-out are more stable, realizes the strong purpose of seal request; The design that the realization that the utility model utilizes trapezoidal hole and wedge-shaped structure to cooperate locks is ingenious reliable, and long service life, the elastic movement of pushing off the slag slide block resets to design and can guarantee its sealing reliability in the utility model, has also reduced the assembling difficulty and the strict high-precision designing requirement of whole device simultaneously.
