Abstract
The invention discloses a novel steam blowing metal hard seal butterfly valve. The butterfly valve comprises a small ball valve, a vapor pipe, a seal valve, a seal valve seat, a sealing ring, vapor pinholes and the like, wherein the seal valve seat is designed as a metal valve seat and is of a metal fire-proof ladder-shaped boss-type structure, and a compound type sealing structure consisting of an elastic expansion ring and a teflon lip-type sealing ring is adopted; the sealing surface of the seal valve is of a 15-degree design, thereby preventing a high-speed fluid from washing part of the seal valve seat, and realizing the self cleaning of the sealing surface; a Cr2O3-based and Ni-based alloy materials are utilized to carry out a surface treatment process, thereby ensuring the smoothness of the seal valve seat, the seal valve and the sealing ring; and the vapor pipe is arranged on the seal valve seat, the inner and outer sides of the vapor pipe are provided with vapor pinholes, the port of each vapor pinhole faces to the seal valve seat, vapors are introduced into the vapor pipe, and the vapors blow the tar adhered to the seal valve seat, so that the tar is molten and cleaned. The butterfly valve provided by the invention has the advantages of reliable seal and flexibility and convenience in open and closure of the valve.
Description
Technical field:
The present invention relates to a kind of metal hard-sealing butterfly valve, be specifically related to a kind of novel steam blast metal hard-sealing butterfly valve.
Background technique:
At present, metal hard-sealing butterfly valve is widely used in coking industry with its high temperature resistant, corrosion-resistant etc. characteristics.In coking industry; Most metal hard-sealing butterfly valve is mounted on the coke oven gas pipe; Because on the coke-stove gas tar is arranged, tar can be condensate on the seal valve seat, because tar is too many; Influence the seal degree of valve and the switch moment of valve and strengthen, might not open thereby cause valve to fit badly maybe.And the existing metal hard-sealing butterfly valve that is installed in coke oven gas pipe, because the defective on project organization and the manufacturing process, the switching of valve is dumb but also imprecision not only, usually is in failure state, and is difficult to guarantee the sealability of valve.
Summary of the invention:
For solving above-mentioned technical deficiency, the object of the present invention is to provide a kind of novel steam blast metal hard-sealing butterfly valve, it is made up of small ball, steam tube, seal valve, seal valve seat, seal ring, steam aperture etc.
The technical solution adopted for the present invention to solve the technical problems is: seal valve seat is designed to metal seat valve, adopts the metal trapezoidal convex table type structure of preventing fires; The compound sealing configuration that adopts elastic expansion ring and teflon lip seal circle to form; The sealing surface of seal valve adopts 15 ° of wedge surface designs, eliminates high-velocity fluid to local the washing away of seal valve seat, realizes the automatically cleaning of sealing surface; Adopt Cr2O3, Ni base alloy material to carry out process of surface treatment, guarantee the degree of finish of seal valve seat, seal valve, seal ring; Seal valve seat is provided with steam tube, and the inside and outside both sides of steam tube are provided with the steam aperture, and the steam microstome feeds steam towards seal valve seat in the steam tube, and steam blast sticks to the tar on the seal valve seat, tar is melted remove.
The invention has the beneficial effects as follows: sealing is reliable, valve opening and closing is flexible, can efficiently remove the tar that sticks on the seal valve seat, and is simple in structure, easily manufactured.
Description of drawings:
Fig. 1 is an overall structure schematic representation of the present invention;
Fig. 2 is a semi-section schematic representation of the present invention;
Among the figure, 1, small ball 2, steam tube 3, seal valve 4, seal valve seat 5, seal ring 6, steam aperture
Embodiment:
Like Fig. 1, shown in Figure 2, a kind of novel steam blast metal hard-sealing butterfly valve comprises small ball 1, steam tube 2, seal valve 3, seal valve seat 4, seal ring 5, steam aperture 6 etc.Seal valve seat 4 is placed in the inside of valve body, and seal valve seat 4 is provided with steam tube 2, and the inside and outside both sides of steam tube 2 are provided with steam aperture 6, and an end of steam tube 2 extracts from valve body, and its port is connected with a small ball 1; The outer side surface of seal valve seat 4 is equipped with seal valve 3, and the step place of seal valve 3 belows is provided with seal ring 5.Seal valve seat 4 is designed to metal seat, adopts the metal trapezoidal convex table type project organization of preventing fires, and guarantees the valve body fire safety; The compound sealing configuration that adopts elastic expansion ring and teflon lip seal circle 5 to form ensures sealability; The sealing surface of seal valve 3 adopts 15 ° of wedge surface designs, eliminates high-velocity fluid to seal valve seat 4 local washing away, and reaches self-cleaning purpose, protects seal valve seat 4 not receive erosion better, increases the service life; Adopt Cr
2O
3, the Ni base alloy material carries out process of surface treatment, guarantees the degree of finish of seal valve seat 4, seal valve 3, seal ring 5.Before seal valve 3 opens or closes, open small ball 1, feed steam to 2 li of steam tubes, winding-up sticks to the tar on the seal valve seat 4, makes the tar thawing, is convenient to seal valve 3 and opens or closes, and seals tightlyer, reduces the switch moment of seal valve 3.
