Description
Technical field
The utility model belongs to valve technology field, is specifically related to a kind of power plant coal-feeding conveyer inlet/outlet push-pull valve.
Background technique
Along with the diversity of power plant's coal used, have the stuck problem of many power plants' frequent appearance of reflection coal-feeding conveyer inlet/outlet push-pull valve recent years, often occurs that valve closes incessantly or pays close attention to the problem of not opening, and has affected the safe and stable operation of unit.Why coal bunker stops up, and one of its reason is the sticky coal chute blockage problem that occurs at its push-pull valve position, has caused the lower coal of whole coal bunker not smooth, further investigation reveals that and occurs that the reason of above problem is as follows:
Conventional electric gate valve is single valve switching plate structure, by gear rack transmission, on its tooth bar and guide rail, after sticky coal, not only make electrical header wearing and tearing accelerate, also cause plate stuck (bar up and do not open, open rear pass incessantly) problem.Conventional electric gate valve valve body is thicker, has many sticky coal chute blockage hidden danger at the position, corner of its Fang Bianyuan, makes valve very easily occur stopping up.Conventional electric gate valve is integral seal structure, and its valve plate present position, can't see in outside, and the open and close state of operation personnel of valve plate do not know, in the time of valve plate jam, cannot immediately find.
Model utility content
The problem existing in order to solve current traditional push-pull valve, the purpose of this utility model is to provide a kind of hydraulic pressure to split push-pull valve, and valve folding condition is intuitively visible, can thoroughly solve the easy obstruction of conventional valve in the market, stuck problem.
For achieving the above object, the technical solution adopted in the utility model:
This novel hydraulic is split push-pull valve, there is valve body, plate is installed in the horizontal concrete chute on valve body madial wall, plate connects reciprocating power mechanism, it is characterized in that: described plate is two, be oppositely arranged, and two plates are positioned at upper and lower two planes, in the time of valve closes, two plates have upper and lower lap; Described valve body is provided with the top and bottom sealing configuration to plate upper and lower surface sealing, described in clamp and in the horizontal concrete chute of plate, be provided with the side sealing structure that horizontal concrete chute and plate side are sealed.
Described top and bottom sealing configuration has side clamping plate and upper cover plate, and side clamping plate and upper cover plate and valve body form filling space, and stuffing box packing is positioned at filling space, and upper cover plate is provided with stuffing box packing hold-down mechanism; Described side sealing structure has the screw being positioned on horizontal concrete chute, is provided with successively sealing column, holddown spring in screw, and adjusting bolt screws in screw, by holddown spring press seal post, makes sealing column be close to plate side.
Described stuffing box packing hold-down mechanism is made up of stuffing box packing pressing plate, holddown spring and hold-down bolt, hold-down bolt compression holddown spring, and holddown spring makes stuffing box packing be close to plate top and bottom by stuffing box packing pressing plate.
Valve body is by rectangle support body and be fixed on the feeding pipe in the middle part of support body, and feeding pipe can be rectangle or circle, and described horizontal concrete chute is positioned on the inner side of rectangle support body of feeding pipe both sides, and described plate is installed on respectively in the horizontal concrete chute of rectangle support body.
In described blanking channel, the blanking channel bore on valve plate top is less than the blanking channel bore of valve plate bottom.
The overlap distance of described two plates is 10-35mm.
The front end side of described two valve plates is ramp structure, and the position that both sides are positioned at horizontal concrete chute has protuberance.
Described reciprocating power mechanism is Electrohydraulic push rod.
Adopt the beneficial effect of technique scheme: this novel hydraulic is split push-pull valve, there are two plates of splitting, two plates are vertically staggering on height mutually, in the time that two plates are closed, the end interlaced (staggered distance is 10mm-35mm) of two plates, can push respectively the coal dust being positioned on plate open, guarantee the closure of valve, solve the not tight drawback of valve plate closure in prior art.Because coal bunker is barotropic state, therefore the sealing of valve is very important, for avoiding the leakage of coal dust, the utility model is provided with top and bottom sealing configuration at gap, the top and bottom place of plate, this top and bottom sealing configuration has side clamping plate and upper cover plate, side clamping plate and upper cover plate and valve body form filling space, and stuffing box packing is positioned at filling space, and upper cover plate is provided with stuffing box packing hold-down mechanism; By the hold-down bolt compression holddown spring in stuffing box packing hold-down mechanism, holddown spring compresses stuffing box packing by stuffing box packing pressing plate, has realized the excellent sealing of valve body and plate.In the time that stuffing box packing is worn and torn, by regulating hold-down bolt press seal filler again, ensure sealing effect.Described plate is by being positioned at the horizontal concrete chute on valve body madial wall, realize the folding of valve by the slip of plate, but there is gap in plate both sides and horizontal concrete chute, the utility model is provided with side sealing structure at this gap location, described side sealing structure has the screw being positioned on horizontal concrete chute, in screw, be provided with successively sealing column, holddown spring, adjusting bolt screws in screw, by holddown spring press seal post, make sealing column be close to plate side, realized the sealing between plate side and horizontal concrete chute.In the time that sealing column is worn and torn, screw in by adjusting bolt, can realize press seal again.Hydraulic pressure is split push-pull valve and is passed through two Electrohydraulic push rods as power, and Electrohydraulic push rod volume is little, flexible movements, and thrust is large, and cost is low, and stroke is stable, and push-and-pull plate does reciprocating action, realizes the switch of valve.Valve plate exposes, and valve plate present position is visible, and its reciprocating power mechanism-Electrohydraulic push rod stroke is certain, and it is known that electric liquid is split push-pull valve on off state.In described blanking channel, the blanking channel bore on valve plate top is less than the blanking channel bore of valve plate bottom, makes blanking channel interior without step, ensures the unobstructed of blanking.The front end side of described two valve plates is ramp structure, and the position that both sides are positioned at horizontal concrete chute has protuberance.The effect that ramp structure can be shoveled coal valve plate in the time of closure, has reduced the resistance of coal to valve plate, and protuberance is positioned at horizontal concrete chute position, in the time that valve plate is closed, the coal entering in horizontal concrete chute is had to the effect that shovels out water conservancy diversion, realizes self cleaning track function.Compared with prior art, have power consumption little, without revealing, can thoroughly solve the easy obstruction of conventional valve in the market, stuck problem, the valve that can be used as powder class material uses.
