Abstract
The utility model provides an up-sealing and material blocking valve without a material bell for a blast furnace. The utility model has the basic structure that a valve frame 10 is connected with a material feeding opening of a material tank of the blast furnace, and the top part of the valve frame 10 is provided with a valve seat 11; an upper opening of the valve seat 11 is connected with a material bucket 1, and a lower opening of the valve seat is matched with a valve board 2. The utility model is characterized in that a driving shaft 6 is arranged on the valve frame 11, an upper crank 4 and a lower crank 7 are fixedly connected with the driving shaft 6, the end part of the upper crank 4 is hinged with the valve board 2 through a connecting rod 3 and the end part of the lower crank 7 is hinged with a cylinder rod of an oil cylinder 8. The material blocking valve provided by the utility model has the advantages of small size, light weight, easy control and capability of simultaneously realizing the functions of material blockage and upper seal.
Description
Technical field
The utility model relates on a kind of blast furnace bell-less and seals material stop valve, is used for iron-smelting blast furnace non-bell furnace top charging equipment switch suitable for reading and sealing, belongs to industrial valve technology field.
Background technology
Batch can in the prior art in blast furnace bell-less top charging equipment backgauge suitable for reading and sealing function separate, and are generally born by material stop valve, two valves of upper sealing valve, and volume is big, and action control is complicated.
Summary of the invention
The purpose of this utility model is to provide on a kind of blast furnace bell-less and seals material stop valve, uses a valve to realize backgauge and two functions of last sealing, thereby reduces equipment volume and be easy to control.
The technical solution of the utility model be achieved in that on this blast furnace bell-less seal material stop valve, basic structure comprises: the vavle shelf that is connected with the blast furnace bucket opening for feed, the vavle shelf top is provided with valve seat, valve seat connection hopper suitable for reading, end opening cooperates with valve plate, it is characterized in that: drive shaft is set on the vavle shelf, affixed crank and the lower crank gone up on the drive shaft, last crank end is hinged by connecting rod and valve plate, and the cylinder bar of lower crank end and oil cylinder is hinged.
The sealing surface of valve plate of sealing material stop valve is a cone surface on the described blast furnace bell-less, and the sealing surface of seat of Pei Heing is a cone surface with it.
The sealing surface of seat surface of sealing material stop valve is provided with sealing-ring on the described blast furnace bell-less.
Sealing material stop valve provided by the utility model, volume is little, and is in light weight, is easy to control, and realizes backgauge and two functions of last sealing simultaneously.
Description of drawings
Fig. 1 is the structure sectional view of sealing material stop valve on the blast furnace bell-less.
Fig. 2 is the I enlarged view of Fig. 1
Among the figure: 1, hopper 2, valve plate 3, connecting rod 4, last crank 6, drive shaft 7, lower crank 8, oil cylinder 9, blast furnace bucket 10, vavle shelf 11, valve seat 12, sealing-ring 2-1, sealing surface of valve plate 11-1, sealing surface of seat
Embodiment
Fig. 1 is the structure sectional view of sealing material stop valve on the blast furnace bell-less, basic structure comprises vavle shelf 10, valve seat 11, valve plate 2, drive shaft 6 is set on the vavle shelf 11, affixed crank 4 and the lower crank 7 gone up on the drive shaft 6, last crank 4 ends are hinged by connecting rod 3 and valve plate 2, and the cylinder bar of lower crank 7 ends and oil cylinder 8 is hinged.
Its principle of work is: oil cylinder 8 promotes lower crank 7 and drives drive shaft 6 rotations, and drive shaft 6 drives goes up crank 4 swings, drives valve plate 2 by connecting rod 3 and moves up and down, the realization valve opening and closing; Sealing surface of valve plate 2-1 is a cone surface, makes with hard wear-resistant material; Sealing surface of seat 11-1 is wear-resisting, corrosion resistant material, and the trim bottom is provided with groove sealing-ring 12 is installed, and forms soft or hard compound sealing pair, further guarantees the stopping property of valve.
When valve plate 2 during in the open site, the raw material in the hopper 1 enters in the batch can 9, when valve plate 2 during in off-position, raw material in the hopper 1 is blocked, can not advance people's blast furnace bucket 9, blast furnace bucket 9 is realized the secluding air sealing and is stopped function reinforced in blast furnace with outside isolated simultaneously.
