Abstract
The utility model belongs to the technical field of valves, and particularly relates to a lever-type stop valve. The lever-type stop valve is characterized by comprising a gate suction cup, a longitudinal support rod I, a horizontal support rod, a longitudinal threaded rod, a lever, a longitudinal support rod II and a planar valve, wherein the gate suction cup is fixedly connected with a blow-off line suction cup, the longitudinal support rod I and the horizontal support rod provided with nuts at ends are fixedly connected with the gate suction cup, the longitudinal threaded rod is in threaded connection with the nuts of the horizontal support rod, the lever is perpendicularly arranged at the bottom of the longitudinal threaded rod and propped with the longitudinal threaded rod, the longitudinal support rod II is perpendicularly arranged at one end of the lever and hinged to the lever, the planar valve is rotationally connected with the longitudinal support rod II, a sealing device is arranged at the top of the planar valve and opposite to an outlet of the gate suction cup, and the middle of the lever is hinged to the longitudinal support rod I. According to the lever-type stop valve, a connecting manner of the threaded rod is used for controlling the valve to open or close outside an ore discharge pipeline, so that the lever-type stop valve is not affected by factors such as ore pulp blockage, valve body corrosion and the like and always keeps a good sealing effect.
Description
Technical field
The utility model belongs to valve technology field, especially relates to a kind of Lever type cut-off valve.
Background technique
Stop valve is a kind of control valve that industrial ore slurry pipeline is carried that is usually used in, and is provided with flow of slurry to the plane flashboard that becomes Vertical direction in valve body, leans on flashboard lifting to open or close the path of ore pulp.In ore discharge pipeline, the normal common stop valve using can bought on the market at present, and its principle is to complete unlatching or closing process by screwing the rotating disk of stop valve.Conventionally under state, stop valve is arranged on the suction pipe road of slag stock pump, when slag stock pump shuts down, the residual ore pulp of inhaling on pipe road need to be discharged, in order to avoid the long-term accumulation of sludge causes line clogging to cause cleaning difficulty.But because the pump housing on ore discharge pipeline is in running, easily fall to waste time, screw mandrel corrosion, the fault such as easily cause that valve body fits badly, causes stop valve life cycle to shorten, maintenance worker's labor intensity increases, cost improves.
Summary of the invention
The purpose of this utility model is to provide a kind of Lever type simple in structure, easy to operate, good sealing effect and ends valve.
The purpose of this utility model realizes by following technical proposals:
Lever type cut-off valve of the present utility model, it is characterized in that comprising the gate sucker being fixedly connected with blow-off line sucker, the longitudinal holding pole I that gate sucker is fixedly connected with therewith and end are with the lateral strut of nut, the longitudinal screw bar being connected with the nut thread of described lateral strut, the lever that is vertically located at described longitudinal screw bar bottom and is abutted against mutually with it, the longitudinal holding pole II that is vertically located at this lever end and is hinged with it, the plane valve that longitudinal holding pole II is rotationally connected therewith, this plane valve top is provided with seal arrangement, and relative with the outlet of described gate sucker, the middle part of described lever and described longitudinal holding pole I are hinged.
Described seal arrangement is sealing gasket.
Advantage of the present utility model:
Lever type of the present utility model cut-off valve adopt ore discharge pipeline utilize outward threaded stem Placement control valve unlatching or close, make Lever type cut-off valve not affected by the factors such as ore pulp shutoff, valve body corrosion, remain good sealing effect.This device is simple to operate, and it is convenient to change, easy operating, and cost is low, and life cycle is long, alleviates labor strength.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, further illustrate embodiment of the present utility model.
As shown in Figure 1, Lever type cut-off valve of the present utility model, it is characterized in that comprising the gate sucker 6 being fixedly connected with blow-off line sucker 5, the longitudinal holding pole I 4 that gate sucker 6 is fixedly connected with therewith and end are with the lateral strut 1 of nut, the longitudinal screw bar 3 being connected with the nut thread of described lateral strut 1, the lever 2 that is vertically located at described longitudinal screw bar 3 bottoms and is abutted against mutually with it, the longitudinal holding pole II 9 that is vertically located at these lever 2 ends and is hinged with it, the plane valve 8 that longitudinal holding pole II 9 is rotationally connected therewith, these plane valve 8 tops are provided with seal arrangement 7, and relative with the outlet of described gate sucker 6, the middle part of described lever 2 and described longitudinal holding pole I 4 are hinged.
Described seal arrangement 7 is sealing gasket.
Working principle of the present utility model:
Before work, first gate sucker 6 is fixed on blow-off line sucker 5, screw longitudinal screw bar 3, make it to decline, it is fulcrum that the lever 2 that is fixed on longitudinal screw bar 3 bottoms be take the hinge being hinged with longitudinal holding pole I 4, lever 2 be provided with the perk of plane valve end, plane valve 8 is docked with the outlet of gate sucker 6, realize the hermetically closing of outlet; Otherwise, screw longitudinal screw bar 3, make it to rise, plane valve 8 is opened, and the outlet of gate sucker 6 can realize ore discharge operation.Plane valve 8 is rotationally connected with longitudinal holding pole II 9, can adjust at any time the angle of plane valve 8, makes sealing tightr.Lever type of the present utility model cut-off valve adopt ore discharge pipeline utilize outward threaded stem Placement control valve unlatching or close, make Lever type cut-off valve not affected by the factors such as ore pulp shutoff, valve body corrosion, remain good sealing effect, utilize lever 2, the lifting force that plane valve 8 ends are subject to is larger, seals tightr.This device is simple to operate, and it is convenient to change, easy operating, and cost is low, and life cycle is long, alleviates labor strength.
Claims (2)
