Abstract
The invention discloses a motor-driven grating type spiral gate valve, and relates to a motor-driven grating type spiral gate valve capable of controlling the conveying of powder. The grating gate valve consists of a motor drive head device, an electric control device, a gate valve body, a gate plate and a transmission device, wherein the motor drive head device is in mechanical connection with a connecting rack through a bolt, a plain washer, an elastic washer and a nut; a motor drive head core shaft sleeve is in mechanical connection with a motor drive head core shaft; and the motor drive head device is electrically connected with the electric control device. When the gate valve is opened and closed, the travel of the gate plate is only one third of gate plate travel of the conventional spiral gate valve, the gate valve slides in the gate valve body, and a screw sleeve which is connected with the gate plate in the transmission device slides under the action of a sealing ring, so that the powder in the gate valve body cannot be leaked to the outside and cannot enter a barrel of the transmission device to influence the normal operation of a screw rod, the screw sleeve and a bearing. The gate valve has a simple structure and low cost and is convenient to mount; and the gate valve can be operated within a long distance in the electric control process, so that the fitness of workers is protected.
Description
Technical field:
The present invention relates to the grid type spiral gate valve that a kind of motor-driven control powder is carried.
Background technology:
The conveying of powder is generally controlled in filler bin and powder delivering pipe road with the mode that opens and closes the spiral gate valve at present; Traditional spiral gate valve exists the Transmission that the long keying speed of gate travel is slow, the easy generation of flashboard leak tightness difference dust leaks, exposes and is very easily stopped up defectives such as causing rotating difficulty by dust; Bring inconvenience to the operator; Even influence production, M/C brings workman's fatigue to receive closely dust pollution again.
Summary of the invention:
The purpose of this invention is to provide a kind of motor-driven grid type spiral gate valve; This gate valve has overcome easy the obstruction by dust of Transmission that the keying speed of conventional helical gate valve existence is slow, the easy generation of flashboard leak tightness difference dust leaks, exposes and has caused rotation to net technological deficiencies such as difficulty; Have that the short keying speed of gate travel is fast, tight the no dust of flashboard sealing leaks, Transmission and dust lattice are from sealing available grease lubrication, the characteristics of operating light and fast.
Technical scheme: a kind of motor-driven grid type spiral gate valve is characterized in that: motor-driven head unit and hitch are by bolt and plain cushion and bullet pad and nut mechanical connection.An a motor-driven core sleeve and motor-driven mandrel mechanical connection.The motor-driven head unit is electrically connected with controller for electric consumption.The grid gate valve is made up of motor-driven head unit and controller for electric consumption, gate valve body, flashboard, driving device four major parts.The gate valve body is provided with vertically arranged, and the middle part is the powder passage of grid.Form by parts assembly weldings such as top panel, lower faceplate, side plate, end plate, little end plate, grid, flashboard end face flange and flashboard slideways; The top panel of rectangle and lower faceplate have the square hole of biasing; At the bottom of the square hole periphery offers and is used to connect the storehouse, the bolt hole of powder pipeline; Two blocks of side plates in the square hole both sides, are welding the flashboard slideway that supports flashboard along the long side weld of upper and lower panel on the side plate, end plate is welded in the setover square hole limit of a side of square hole; Little end plate is welded in the square hole limit on end plate opposite; Grid and end plate are welded in square hole middle part abreast, the width of grid be slightly larger than square hole the length of side 1/3rd, the cross section that the powder passage could stopped or open to the powder passage that the neutral of grid both sides and the formation of the square hole of lower faceplate communicate up and down, the flashboard of horizontal motion; The middle part of flashboard is a neutral, and flashboard end face flange is welded in the other end relative with end plate of upper and lower panel.The parallel flashboard that can on the flashboard slideway of side plate, slide of placing between the upper and lower panel, the distance that flashboard slides is the stroke that 1/3rd of the square hole length of side is promptly accomplished switching motion.Flashboard is divided into three parts along direction of slip; Middle 1/3rd are the neutral gear of no plate; Each 1/3rd position, two ends are two little flashboards, and three steel plates that two little flashboards are welded in below it link into an integrated entity, and wherein are welded in two slide plates that steel plate is a flashboard of both sides; A steel plate in the middle of being welded in is the driver plate that an end is provided with pin-and-hole, and flashboard utilizes two slide plates to be placed on the flashboard slideway of gate valve body.The grid cross section of gate valve body is the shape of falling v, and its lower plane is pasting the last plane of flashboard, and the width of grid bottom slightly is wider than the neutral at flashboard middle part.The driving device of control flashboard switching motion is provided with butt flange; Be installed in the flashboard end face flange outside of gate valve body with bolt; In driving device simplified screw rod and swivel nut are installed, screw rod one end cooperates with swivel nut, and the other end is with the bearing supporting and extend to the outer fitting operation motor driver of cylindrical shell; The end of swivel nut in cylindrical shell cooperates with screw rod; Stretch out the simplified other end and shut and be provided with articulated joint, this articulated joint is hinged with the pin-and-hole of the driver plate under bearing pin and the flashboard, and the cylindrical shell of driving device is provided with seal ring between an end that is provided with butt flange and swivel nut can guarantee the sealing of screw rod, swivel nut, bearing and lubricated.
Technique effect: the stroke of flashboard has only 1/3rd of conventional helical gate valve gate travel when opening and closing gate valve; Flashboard slides in the gate valve body; The swivel nut that connects flashboard in the driving device is in the effect lower slider of seal ring; So the powder in the gate valve body both can not leak into the outside, the cylindrical shell that also can not get into driving device influences the normal operation of screw rod, swivel nut and bearing.Realized that keying is fast light, good seal does not have the technical goal that dust leaks.Because adopt such scheme, simple in structure, easy for installation, cost is low.But automatically controlled remote servicing, the protection workman is healthy.
