Description
Technical field
The utility model relates to the high-pressure water descaling system of metallurgy industry, specifically a kind of to steel rolling, roll the metallurgy de-scaling injection valve that plate carries out de-scaling.
Background technique
In high-pressure water descaling system, the de-scaling injection valve is installed on the terminal of system, and under the effect of control system bleed pressure, valve is in normally off.After the steel plate for the treatment of de-scaling entered predetermined station, control system obtained the de-scaling signal, and two-position-five-way solenoid valve gets electric commutation, valve open, and descaling system begins the de-scaling of inject high pressure water; When steel plate leaves predetermined station, control system obtains finishing the de-scaling signal, and two-position-five-way solenoid valve gets electric commutation, and the de-scaling injection valve cuts out, and de-scaling finishes.Notice of authorization number discloses a kind of de-scaling injection valve of being used widely for the Chinese patent of CN2869461Y " de-scaling injection valve ", it mainly by the valve body that has water inlet, osculum and valve pocket, have that down valve gap and lining, valve seat, flap and the driving mechanism of air inlet/outlet are formed, wherein, lining, valve seat and flap are positioned at valve pocket, and driving mechanism comprises valve gap, the cylinder upper cover that has air inlet/outlet, cylinder and the piston that has following air inlet/outlet.Because what this de-scaling injection valve adopted is the balanced type cone valve structure, the sealing surface of flap and valve base chamber can move along with moving up and down of flap, in the process that valve is being closed and just opened, owing to have impurity in the structure of valve and the medium, to sealing surface easily produce wearing and tearing and wash away, the working life of sealing surface is very limited, and then has influenced the working life of this de-scaling injection valve.In addition, this de-scaling injection valve is under accident condition such as cut off the power supply, die, and valve should be closed condition, but under the pressure medium effect, move on the flap, make valve be opening state, thereby security incident occurs, promptly there is potential safety hazard in this de-scaling injection valve in the use process.
The model utility content
The purpose of this utility model is the deficiency at above-mentioned de-scaling injection valve, and a kind of long service life, safe and reliable metallurgy de-scaling injection valve are provided.
For achieving the above object, a kind of metallurgy de-scaling injection valve that the utility model provides by the valve body that has water inlet, osculum and valve pocket, have the lower cover of air cylinder of air inlet/outlet down, and lining, plunger, valve rod and driving mechanism is formed.Wherein, described lining and plunger are positioned at described valve pocket, and described driving mechanism comprises cylinder upper cover, cylinder, piston and the piston rod that has air inlet/outlet, and described plunger has pod apertures, are provided with seal ring between described lining and the described plunger.Also have the medium fenestra that is used for being communicated with described pod apertures and osculum under the state of opening of valves on the lining, its specialization is: the inboard of described lining has seal groove, and the seal ring between described lining and the plunger is arranged in the described seal groove; The upper side of described plunger has at least one medium through hole that is used to be communicated with described pod apertures and osculum.
Also be provided with wear ring between described piston rod and the cylinder upper cover.
Preferably also be provided with leak hunting aperture on the described lower cover of air cylinder.
The upper end of described piston rod is provided with performer, and described cylinder upper cover is provided with the inductive transducer that cooperates with described performer by support.
Described valve body and lower cover of air cylinder are the valve body and the lower cover of air cylinder of forging material.
Compare with de-scaling injection valve in the past, seal ring in the utility model between lining and the plunger is arranged in the lining, and the upper and lower part of lining is equal and plunger seal, not only improved the overall sealing performance of valve, and seal ring is difficult for being damaged by medium and the impurity in medium, its life-span significant prolongation, so the life-span of whole de-scaling injection valve obtain prolonging; What the utility model adopted is the balanced type sliding valve structure, and have medium through hole in plunger upper part, under control system such as dies at situation, even the pressure of medium makes plunger be pushed up upper end to valve pocket, valve still is in closing state, has guaranteed the safety of whole descaling system.
