The utility model offers a worm gear worm valve electric and hydraulic motive fin-inserted double dust valve, mainly including a cylinder body, a valve and a controlling device. The utility model is characterized in that a cylinder one 1, a cylinder two 2, a cylinder three 3 and a cylinder four 4 are all in series connection, and the cylinder one 1 and the cylinder two 2 are provided with a worm gear worm rod reduction gearbox 6 and a controlling safety valve 5. The cylinder two 2 and the cylinder three 3 are provided with a inserting plate valve 7 controlled by an upper valve electric and hydraulic push rod 8; The cylinder three 3and the cylinder four 4 are provided with a inserting plate valve 9 controlled by an upper valve electric and hydraulic push rod 10. The utility model has advantages of a compact structure, low leakage, good resistance of impact and wear, good safety performance, and convenient maintenance, extensively used in the course of industry producing process requiring remote control or field control unloading ashes in metallurgy, mining, building materials, electric power and chemical industries and so on.
Description
Affiliated field
The utility model relates to a kind of worm and gear valve electricity spile type Double-deck cinder discharge valve that surges.
Background technique
The unloading valve that past people is used has two types, the isostructural unloading valve of mushroom hair style, mitre velve that the first is traditional, it exists volume big, the leak-down rate height, valve head is easy to wear and get stuck, motor easily burns, and can't enter defectives such as automatic control in the industrial production flow process; It two is the board-like unloading valves of electric hydraulic brake, and the defective that its exists is that the spiral valve one that is used to overhaul is must artificial execute-in-place, and intensity and difficulty are bigger, the 2nd, and easy-to-rust, distortion and cause and can't use.
Summary of the invention
That employing provided by the utility model integrates is mechanical, electrical, liquid, volume remote controlled a kind of worm and gear valve electricity little, that leak-down rate is low of controlling surge the spile type Double-deck cinder discharge valve.
The utility model mainly is made up of four joint cylindrical shells, two-layer plates, one Safety valve and a plurality of control gear, and each saves and is series connection between cylindrical shell, is provided with Worm-gear type electric safe valve between cylindrical shell one and the cylindrical shell two; Be provided with plate between cylindrical shell two and the cylindrical shell three, a side of last plate is connected by support and the last valve electricity push rod that surges; Be provided with lower plugboard between cylindrical shell three and the cylindrical shell four, a side of lower plugboard is connected by support and the following valve electricity push rod that surges.
Between the utility model cylindrical shell and the valve and all be designed to flange between cylindrical shell and the plate and be connected, last valve electricity push rod and the following valve electricity push rod that surges that surges is provided with pressure relay, the sealing material that cylindrical shell is asked is that the metal frame rubber sheet gasket outside adds straight line type rubber filler rod, and it adopts electric controller to realize scene or far distance automatic controlling.The utility model structurally adopts tubular construction, and upper and lower plate is connected with flange with cylindrical shell, has a style of one's own, and is easy for installation; Seal face materials is that metal frame rubber sheet gasket and straight line type rubber filler rod combine, and can regulate guarantees lock wind effect reliably, and leak-down rate is controlled in 0.05%; Upper and lower plate adopts high manganese steel material, its good rigidly, shock-resistant, wear-resistant; Adopt the Electrohydraulic push rod source moving linearly that is used as power, use reliably, the life-span is long, has good overflow performance, and the overload protection performance is strong; Supporting electric controller, it integrates mechanical, electrical, liquid, controls, can realization scene or distant control, can set pattern, free operation according to unloading ash capacity automatically.
The utility model Safety valve adopts the worm reduction box control mechanism, has both improved the rigidity of structure, and anti-curved corrosion protection can realize laborsaving control again, is convenient to operation.
Description of drawings Fig. 1 is a structural representation plan view of the present utility model.
Fig. 2 is the utility model plan view.
Embodiment
According to shown in Figure 1, worm and gear valve electricity surges, and the spile type Double-deck cinder discharge valve comprises 1, cylindrical shell one; 2, cylindrical shell two; 3, cylindrical shell three; 4, cylindrical shell four; 5, Safety valve; 6, worm reduction box; 7, go up the plate valve; 8, go up the valve Electrohydraulic push rod; 9, lower plugboard valve; 10, following valve Electrohydraulic push rod; 11, stroke switchgear.
Be provided with Safety valve 5 between cylindrical shell 1 and the cylindrical shell 22, by worm reduction box 6 controls.Be provided with plate valve 7 between cylindrical shell 22 and the cylindrical shell 33, connect control by last valve Electrohydraulic push rod 8; Be provided with lower plugboard valve 9 between cylindrical shell 33 and the cylindrical shell 44, by valve Electrohydraulic push rod 10 connections down.Upper and lower valve Electrohydraulic push rod is realized electrical control by position limit switch 11, can realize telecontrol.
The worm and gear valve electricity described in the utility model spile type Double-deck cinder discharge valve that surges, after connecting power supply, last valve Electrohydraulic push rod 8 is opened plate valve 7 automatically, to limit switch 11, stops the several seconds discharging, close then and close push-pull valve door 7, change 9 work of lower plugboard valve over to, lower plugboard valve 9 is opened plate to limit switch by following valve Electrohydraulic push rod 10, stops the several seconds discharging, close lower plugboard valve 9 plates then to limit switch, change 9 work of plate valve over to.So alternation to the unloading ash capacity of setting, stops overall process work automatically.The electricity plate Double-deck cinder discharge valve control mode of surging can be counting working method and timework mode, can control at the scene and distant control.In moving the way, run into suddenly when getting stuck, the pressure relay electric device output signal that Electrohydraulic push rod is equipped with, the control Electrohydraulic push rod is opened rapidly again and is closed, and gets rid of the defective that gets stuck.Control worm reduction box 6 control Safety valves 5 by the maintainer then, realize operations such as removing, maintenance and maintenance.
