Abstract
The utility model relates to a elastic-metal hard-sealing butterfly valve which comprises a valve body, a butterfly board and a valve rod, a 'U' shaped seal ring is provided between the valve body and the butterfly board, the arc surface of the 'U' shaped seal ring is contact with the end-face of the butterfly board, one end of which is fixed on the valve body. The 'U' shaped metal seal ring has a certain elastic effective and excellent sealing effective with the butterfly board in no mater high or low temperature conditions. The 'U' shaped seal ring has nearly no friction working with the butterfly board, which makes the device a long service life, and the function of closing more and more tightly. The utility model has the advantages of simple and compact structure, light in weight, convenient operation, corrosion resistance, high and low temperature resistance, reliable sealing effect, and easy to install and detach. The utility model is the best flow regulation and liquid block device applied to the medium-pipes the temperature in which is no more than 550 degree centigrade in the occasions of metallurgy, electric power, petrochemical industry, steam, air, coal gas, fuel gas and water supply and wedge industry.
Description
[technical field]
The utility model relates to a kind of elastic metallic hard seal butterfly valve that seal arrangement between valve body and the butterfly plate is carried out architecture advances.
[background technique]
Butterfly valve is a kind of device that is widely used in making the adjusting flow on the medium pipelines such as metallurgy, electric power, petrochemical industry, steam, air, coal gas, inflammable gas and plumbing and blocks fluid.But owing to adopt the rubber sealing circle between the valve body of existing reed valve and the butterfly plate mostly, rubber material comprises nitrile butadiene rubber, natural rubber and neoprene, because the rubber resistance to high temperature is poor, under the situation of variation of ambient temperature, aging easily distortion, thereby its sealability will be affected.
[model utility content]
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of elastic metallic hard seal butterfly valve that seal arrangement between valve body and the butterfly plate is carried out architecture advances.
The technological scheme that its technical problem that solves the utility model adopts is: the elastic metallic hard seal butterfly valve, comprise valve body, butterfly plate and valve rod, between described valve body and butterfly plate, be provided with " U " RunddichtringO, the arc shaped surface that is somebody's turn to do " U " RunddichtringO contacts with the butterfly plate end face, and an end that is somebody's turn to do " U " RunddichtringO is fixed on the valve body.
Described butterfly plate is the plane of inclination with the end face that contacts between " U " RunddichtringO.
One side of described valve body is provided with pressing plate, and this pressing plate is fixedlyed connected with valve body by bolt.
Described " U " RunddichtringO the other end is fixed on the pressing plate.
The beneficial effects of the utility model are: adopt metal " U " RunddichtringO, have certain elasticity, no matter under the situation of high temperature or low temperature, it and butterfly plate all have good sealing; Almost there is not friction between " U " RunddichtringO and the butterfly plate, long service life, and have the tight more function in pass more; Have simple in structurely, compact, in light weight, be easy to mount and dismount flexible and convenient operation, corrosion-resistant, high temperature resistant and low temperature, the reliable advantage of sealability.Be that a kind of medium temperature that is applicable to is not more than the optimum device of making the adjusting flow on 550 ℃ of medium pipelines such as metallurgy, electric power, petrochemical industry, steam, air, coal gas, inflammable gas and plumbing and blocking fluid.
[description of drawings]
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structure for amplifying schematic representation of A part among Fig. 1.
Among the figure: 1-valve body, 2-butterfly plate, 3-pressing plate, 4-" U " RunddichtringO, 5-handle, 6-valve rod.
[embodiment]
Referring to Fig. 1, the elastic metallic hard seal butterfly valve comprises valve body 1, butterfly plate 2 and valve rod 6, valve rod 6 both can supporting operating grip 5, also can with electronic, surge or the steam-operating device links to each other, as shown in Figure 2, side at described valve body 1 is provided with pressing plate 3, and this pressing plate 3 is fixedlyed connected with valve body 1 by bolt; Be provided with " U " RunddichtringO 4 between described valve body 1 and butterfly plate 2, an end that is somebody's turn to do " U " RunddichtringO 4 is fixed on the valve body 1, and described " U " RunddichtringO 4 the other ends are fixed on the pressing plate 3.Described butterfly plate 2 is the plane of inclination with the end face that contacts between " U " RunddichtringO 4, in practice, the plane of inclination of butterfly plate 2 is provided with seal ring, the arc shaped surface of " U " RunddichtringO 4 contacts with butterfly plate 2 end faces, making does not almost have friction between " U " RunddichtringO 4 and the butterfly plate 2, increase working life, and had the tight more function in pass more; The utility model adopts metal " U " RunddichtringO 4, has certain elasticity, and no matter under the situation of high temperature or low temperature, it and butterfly plate 2 all have good sealing; The utlity model has simple in structurely, compact, in light weight, be easy to mount and dismount flexible and convenient operation, corrosion-resistant, high temperature resistant and low temperature, the reliable advantage of sealability.Be that a kind of medium temperature that is applicable to is not more than the optimum device of making the adjusting flow on 550 ℃ of medium pipelines such as metallurgy, electric power, petrochemical industry, steam, air, coal gas, inflammable gas and plumbing and blocking fluid.
