When rotating disk gate valve is worked under the environment of many dust, sealing surface is affected by dust easily and occurs wearing and tearing, affects the sealability of gate valve.The recovery technique of existing valve seal performance to the repairing function of rotating disk Gate-valve sealing performance, be not too obvious, and most of technology cannot be accomplished uninterrupted reparation.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of plate valve and method thereof of sustainable reparation sealability is provided.
The plate valve of sustainable reparation sealability comprises valve seat, rocking bar, back shaft, spiral compression spring, round end jacking block, disk flap, valve gap, link, bearing pin, rocking arm, major axis; Disk flap is enclosed within the butt end of back shaft, spiral compression spring is positioned in the hole of back shaft, round end jacking block is also positioned at the hole of back shaft, spiral compression spring one end is enclosed within the taper end of round end jacking block, the other end of spiral compression spring props up back shaft, the round end of round end jacking block holds out against disk flap, the taper end of back shaft is arranged on rocking bar, rocking bar is arranged on major axis, major axis is connected with rocking arm through the aperture of valve gap, link is connected with rocking arm by bearing pin, and insert in the bearing hole of valve seat the lower end of major axis, and valve gap is arranged on valve seat by screw.
Described back shaft, spiral compression spring, round end jacking block, four members of disk flap form sealability repairing mechanism together,
Described disk flap and back shaft form and can be dynamically connected, and disk flap both can rotate on back shaft, also can on back shaft, axially move.
Described round end jacking block and the hole of back shaft form and can be dynamically connected, and the hole inwall that round end jacking block can paste back shaft axially moves.
Between described rocking bar and major axis, adopt key to be connected, rocking arm is fixed by screws on major axis, and in the switching process of valve, rocking bar, major axis, rocking arm three connect firmly and be integral, without relative movement.
The flange mouth of described valve seat is material outlet, and the flange mouth of valve gap is material inlet, and the flow direction of material is unique.
Between described valve seat and valve gap, between disk flap and valve gap, between major axis and valve gap, all adopted seal approach, to guarantee the overall tightness of plate valve.
Described link is connected with external power supply, and external power supply can adopt cylinder, oil hydraulic cylinder etc.
A kind of using method of plate valve of sustainable reparation sealability comprises the following steps:
1) link obtains driving force from external power supply, by bearing pin, drives rocking arm, and rocking arm drives major axis to rotate, and major axis drives rocking bar, and rocking bar drives disk valve flap translational by back shaft, makes plate valve realize the action of closure or openness;
2) when there are wearing and tearing in the annular seal surface of contact of disk flap, round end jacking block continues to hold out against disk flap under the effect of spiral compression spring pretightening force, so just, can compensate the wear extent of disk flap annular seal surface of contact, the sealability of valve is maintained.
Disk valve clack sealing surface of the present invention adopts wearable hard alloy material or wear-resisting Reinforced structure pottery, smooth surface, hardness is very high, having solved sealing surface washes away easily by not high problem of erosion, life-span because of material, for user brings desirable using effect and economic benefit, greatly improved Security, the stability of equipment operation.Disk flap is subject to the pretightening force effect of spiral compression spring in the course of the work all the time, spring force fits tightly valve clack sealing surface and sealing ring surface, and allow again flap moving axially, thereby contribute to compensate expanding with heat and contract with cold of valve components, and can overcome the impact of any economy on sealing, can also prevent that particle media from entering between sealing surface.The official post of valve clack sealing surface frictional force in tangent direction to sealing ring surface obtains flap can produce rotation in opening-closing process, this characteristic makes can produce grinding, polishing action between sealing surface, thereby the sealability that makes valve obtains lifting to a certain extent, and can maintain higher level.
