Abstract
The utility model provides a centring butt-clamping all rubber liner butterfly valve, which is composed of a valve body, a rotating shaft, a shaft sleeve, a valve plate, and a liner bushing. The utility model is characterized in that the rotating shaft and the valve plate are in hexagon connection; the valve plate is provided with through holes, and the edge of the valve plate is provided with an annular groove for reinforcing the bonding force between the valve plate and a coating layer; the coating layer and the liner bushing are made of rubber with good corrosion-resisting performance. The utility model which has the advantage of long service life and has a use function within 0.6 MPa-1.6 MPa and-45-+205 DEG C temperature is suitable for various pipeline systems for acid liquid, aqueous alkali liquid, freshwater, sewerage, sea water, brine, steam, coal gas, and other kinds of gas.
Description
The utility model relates to the full butterfly valve of a kind of center line wafer type, is made of valve body, valve plate, rotating shaft, lining and valve seat, is specially adapted to have in the middle of corrosive acid-base class fluid pipeline transporting system.
In the prior art, for corrosion resistance and the working life that increases butterfly valve, the material of making valve plate adopts stainless steel usually, increased its working life though this measure is corresponding, but its cost is expensive, adopt titanium alloy that corrosion resistance and working life are improved greatly, yet the prices of raw and semifnished materials are also quite high.The patent No. is 87206823 Chinese patent " valve plate is coated with the butterfly valve of organic matter layer ", its feature is that the outer surface at valve plate is coated with one deck organic material, preferably select for use all stronger rubber of antiwear property and decay resistance to make clad, valve rod and valve plate adopt taper pin to be connected, and it is not firm that its deficiency is that coating combines with valve plate; The taper pin end face exposes with aggressive medium and contacts, and regardless of selection, this structure all can be corroded, and contacts not only valve plate in addition with medium, also has other parts, all will influence its working life.
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art and a kind of corrosion-resistant, the life-span is long, price is low full butterfly valve of center line wafer type is provided.
The purpose of this utility model can reach by following measure: the rotary shaft hole on the valve plate is made interior regular hexagon, the part that rotating shaft (2) matches with rotary shaft hole on the valve plate is made outer regular hexagon, rotating shaft (2) penetrates the endoporus of valve plate (4), cooperation with hexagonal hole and axle fixes, so just realized the integrity that valve plate is rubber-coated, on valve plate, leave several through holes, these through holes are along its radial equipartition, leave circular groove in the valve plate outer rim, the outer surface of valve plate evenly coats one deck rubber material.
The purpose of this utility model can also reach by following measure: the rubber layer thickness that valve plate coats is not less than 3～5mm, said rubber material is that butyronitrile rubber adds silicon and fire retardant, the through hole number of being opened on the valve plate is no less than 20, and the aperture is not less than φ 3mm.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the plan view of the full butterfly valve of center line wafer type;
Fig. 2 is the side view of the full butterfly valve of center line wafer type;
Fig. 3 is a plan view A-A sectional view.
The utility model is described in further detail below in conjunction with accompanying drawing:
Valve body among Fig. 1 (1) is by gray cast iron or spheroidal graphite cast iron manufacturing, also can be according to usage requirement with aluminum alloy, Cuprum alloy, carbon steel manufacturing, and the hole of being opened on it is no less than 4, and these holes are that to be connected pipeline requisite.
Among Fig. 2 and Fig. 3, rotating shaft (2) is that orthohexagonal cooperates with the axis hole of valve plate (4), the mating part that is rotating shaft (2) and valve plate (4) is orthohexagonal hexahedron, the corresponding matching hole of valve plate also is orthohexagonal hexagonal hole, like this be connected just to have removed from used dowel fixes, thereby make valve plate (4) can obtain more complete rubber adhesive, can as prior art, not expose the decline that brings resistance to corrosion because of pin, leave on the valve plate (4) and be no less than 20 through holes, the aperture of through hole is no less than φ 3mm, circular groove is left at edge at valve plate, so not only increased the area of contact of encapsulate, and in encapsulation process, colloid is filled through hole and is formed rubber column, and these rubber columns couple together the rubber layer of valve plate (4) two bread, make the rubber of clad and valve plate (4) have more integrity, connect more firmly, improved the internal pressure-resistant performance.Clad (6) is by adding the surface that gentle mould-forming wraps in valve plate (4), and can make it to couple together by the through hole on the valve plate, and the used material of clad is that butyronitrile rubber adds silicon and fire retardant.The axle sleeve (3) that is sleeved on rotating shaft (2) outside uses bronze or spheroidal graphite cast iron, and the lining of ring (5) is installed on the inner ring of valve body (1), and lining (5) adopts and valve plate clad (6) same material.
The utility model is the full line with rubber dish of an a kind of center line wafer type valve, densely cross 35% at technical hydrochloric acid, temperature+120 ℃, pressure 1.2 MPas, operating conditions under, its working life is more than 1 year.Be applicable in the pipe-line system of gases such as various acid-base class liquid, fresh water, sewage, seawater, salt solution and steam coal gas.
The utility model has following advantage than prior art:
1. open hole and its edge at valve plate and drive cannelure valve plate is connected firmly, have more globality, anti-pressure ability is stronger;
2. the fourth eyeball class rubber of filling a prescription owing to the employing special type, good seal performance, corrosion resistance is strong, long service life;
3. valve plate adopts positive six sides to be connected with rotating shaft, and reliable operation is easy to loading and unloading;
4. have in pressure 0.6～1.6 MPa, temperature-45 ℃～+ 205 ℃ of scopes and use, application surface is wideer.
Claims (3)
1, the full butterfly valve of a kind of center line wafer type is made of valve body, valve plate, rotating shaft, lining and valve seat, it is characterized in that:
A. the rotary shaft hole of valve plate (4) is made interior regular hexagon, and the corresponding cooperation position of rotating shaft (2) is made outer regular hexagon, and valve plate adopts six sides to be connected with rotating shaft, has guaranteed the complete of valve plate cylinder-packing rubber;
B. leave several through holes on valve plate, these holes are radially uniform, and leave circular groove at the edge of valve plate;
C. the valve plate outer surface coats one deck uniformly as glue material.
