Abstract
The utility model relates to a novel sluice valve, including valve body, disk seat, flashboard, valve rod, valve gap, drive mechanism, disk seat and the sealed face spraying wear -resistant alloy material of flashboard, mainly be that the flashboard comprises valve clack and slide, the valve clack openly has the sealed face in the plane of mutually supporting with the disk seat, the plane of slide one side for connecting the valve clack back, and the slide opposite side has the scarf of mutually supporting with the valve body, slide upper end and valve rod lower extreme fixed connection, valve clack back centre of a circle department installs in the slide centre bore through connecting screw rod and nut, a fixed spherical spacer on the valve clack in the connecting screw rod outside, and a fixed connection conical surface gasket on the slide in the connecting screw rod outside, spherical spacer's sphere contacts with the conical surface of conical surface gasket each other. But at the plane degree of adaptability of the sealed face of valve clack and disk seat wedging in -process automatic regulating valve lamella with the valve seat seal face, have wear -resisting, be able to bear or endure to erode, characteristics such as sealing performance is good, product long service life. Be applicable to the control valve of solid material pipeline.
Description
Technical field
This utility model belongs to valve field, especially with regard to a kind of sluice valve.This utility model is applicable to the control valve of the industry solid material pipelines such as chemical industry, electric power, metallurgy, mine, building materials, grain.
Background technology
In the dischargings of industry medium conveyance conduit such as electric power, metallurgy, mine, building materials, grain or the ash-unloading tube road of cleaner, it is generally adopted baiting valve and controls the conveying of solid material, its structure is generally made up of valve body, valve seat, flashboard, valve rod, valve gap, drive mechanism, utilizes the realization that cooperates of flashboard and valve seat to turn off or on pipeline.It major downside is that and opens and closes in engagement process at flashboard and valve seat, and solid particle medium can abrade and wear and tear flashboard and sealing surface of seat, and when flashboard is opened, solid particle medium is very strong to the erosion of body cavity, makes product very short for service life, and sealing reliability is very poor.
Summary of the invention
The purpose of this utility model be for prior art exist shortcoming, it is provided that a kind of wear-resisting, resistance to erosion, sealing reliability are good, the Novel sliding plate valve of long service life.
The technical solution of the utility model includes valve body, valve seat, flashboard, valve rod, valve gap, drive mechanism, valve seat and ram seal face spraying abrasion-proof alloy material；Mainly flashboard is made up of flap and slide plate, and flap front has the flat seal face cooperated with valve seat, and slide plate side is the plane connecting the flap back side, and slide plate opposite side has the wedge surface cooperated with valve body, and slide plate upper end is fixing with valve rod lower end to be connected；Flap back side circle centre position is arranged in slide plate centre bore by connecting screw rod and nut, the flap connecting outside screw rod fixes a spherical pad, on the slide plate connecting outside screw rod, the fixing conical surface connecting a conical surface pad, the sphere of spherical pad and conical surface pad contacts with each other.
Preferably, bottom body cavity, it is shaped with ash discharge groove, this ash discharge rooved face pile-up welding hard alloy.
Preferably, pile-up welding hard alloy seal receptacle on the valve gap of stem outer circumference, stem lower portion periphery is provided with the conical seal (contact) face cooperated with described seal receptacle.
The utility model has the advantages that flashboard is made up of flap and slide plate, when valve rod promotes slide plate to move down, by flap and sealing surface of seat wedge tight sealing engagement, flap with valve seat wedging process can be automatically adjusted the plane fitness of valve clack sealing surface and sealing surface of seat；Meanwhile, at valve clack sealing surface and sealing surface of seat surfacing Hardmetal materials；There is the features such as wear-resisting, resistance to erosion, good seal performance, long product lifecycle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1 valve body, 2 valve seats, 3 flaps, 4 slide plates, 5 spherical pads, 6 conical surface pads, 7 nuts, 8 valve rods, 9 valve gaps, 10 seal receptacles.
Detailed description of the invention
Novel sliding plate valve as shown in Figure 1, including valve body 1, valve seat 2, flashboard, valve rod 8, valve gap 9, drive mechanism, valve seat 2 and ram seal face spraying abrasion-proof alloy material, valve seat 2 is arranged in valve body 1 intake channel；Flashboard is made up of flap 3 and slide plate 4, flap 3 front has the flat seal face cooperated with valve seat 2, slide plate 4 side is the plane connecting flap 3 back side, slide plate 4 opposite side has the wedge surface cooperated with valve body 1, namely being shaped with, at valve body 1 exit passageway mouth, the wedge surface that the wedge surface with slide plate 4 cooperates, slide plate 4 upper end is fixing with valve rod 8 lower end to be connected；Flap 3 back side circle centre position is arranged in slide plate 4 centre bore by connecting screw rod and nut 7, the flap 3 connecting outside screw rod fixes a spherical pad 5, fixing connection one conical surface pad 6 on the slide plate 4 connecting outside screw rod, the conical surface of the sphere of spherical pad 5 and conical surface pad 6 contacts with each other, slide plate 4 wedging process can be automatically adjusted the plane fitness between flap 3 sealing surface and valve seat 2 sealing surface, improve and seal matching property.
Valve body 1 intracavity bottom is shaped with ash discharge groove, this ash discharge rooved face pile-up welding hard alloy, improves the abrasion resistance of valve body 1.
Pile-up welding hard alloy seal receptacle 10 on the valve gap 9 of valve rod 8 periphery, valve rod 8 bottom periphery is provided with the conical seal (contact) face cooperated with described seal receptacle 10, improves lumen sealing property.
