The utility model provides high valve body working surface, gate receive the wearability of impact surface, strengthen the sealing performance of gate and valve body, make the scum valve can stand the hard fixed wearing and tearing of dry sediment, carry liquid solid, the double-phase medium of gas-solid in the easy wearing and tearing pipeline of trades such as suitable mine, coal-fired power plant, building materials, chemical industry.
Description
Technical field
The utility model relates to a kind of technology of valve.
Background technique
Warp is to survey data analyses such as mine, thermal power plants, the serviceability of the valve that temperature formula or dry type transporting system adopt is extremely low, occurs must changing whole valve after wearing and tearing, the leakage, has not only influenced to connect the requirement of producing, and the increasing cost of production is taken a lot of work, consuming time.
Summary of the invention
The utility model purpose is to design a kind of serviceability good manual, the wear-resistant slag-off valve of hydraulic pressure.
The utility model comprises support, the bonnet that is connected with support, the valve body that is connected with bonnet, and the flashboard of cooperation and valve body, be connected the flashboard start-stop device of flashboard upper end, the import of valve body, outlet are respectively equipped with wear-resisting interior cover, the inlet passage of valve body is provided with soft sealing layer, and the front-end face of flashboard is provided with wear-resisting liner.
Because above-mentioned design, improved the be hit wear resistance of face of valve body working surface, gate, strengthen the sealability of gate and valve body, make slag-off valve can stand the hard fixing wearing and tearing of dried slag, be fit to carry in the industry pipelines easy to wear such as mine, coal-fired power plant, building materials, chemical industry liquid-solid, gas-solid two-phase medium.
In order further to improve working life of the present utility model, valve body import of the present utility model is connected on the valve body by bolt, can need not integral replacing by the import of local replacing valve body, increases work efficiency, and reduces cost.
For strengthening the sealing of flashboard and valve body, the ear end face of the utility model flashboard is inclined-plane forward from top to bottom, be provided with wear-resisting coning sleeve at the valve outlet place relative with flashboard, the face of the relative flashboard of this wear-resisting coning sleeve is inclined-plane forward from top to bottom, flashboard is in the course of action of start or stop, pushed by wear-resisting coning sleeve, fit tightly gradually on the soft sealing layer of valve body import.
In addition, the cylinder of the face of the wear-resisting coning sleeve towards flashboard of the present utility model for being interrupted, the gate action not only is convenient in this design, the power of reducing friction, can effectively reduce the working power of gate hoist, and utilize the slag of in time removing on gate ear end face and valve export on the other side, make gate have better sealability.
For reducing labor intensity, the utility model can also substitute traditional handwheel by hydraulic pressure, be that the flashboard start-stop device is for comprising hydraulic jack and hydraulic-pressure pump assembly, the hydraulic jack upside-down is arranged on the support, flashboard is connected the hydraulic jack lower end, the hydraulic push rod upper end of hydraulic jack is supported on the support upper end, the hydraulic-pressure pump assembly is connected bonnet one side, and the oil circuit that layout is connected with hydraulic jack on support, among the design, hydraulic jack is is inverted assembling, can solve the sealing of taking mineral out of when push rod passes in and out valve body and damaging oil cylinder and push rod up and down, thus the working life of improving oil cylinder.
