Abstract
The utility model relates to an anti-corrosion butterfly valve in a corresponding-clamp type, which comprises an upper valve body, a lower valve body, an upper valve handle, a lower valve handle, a sealing seat and a valve plate. The utility model is characterized in that the upper valve body and the lower valve body are fixedly connected by screw bolts to enable the sealing seat to be arranged in the valve bodies. The valve plate is arranged in the sealing seat. The two ends of the valve plate are connected by the upper valve handle and the lower valve handle. The utility model has the advantages of novel structure, good sealing effect, convenient installation, convenient repair, low cost and high productive efficiency.
Description
The utility model relates to a kind of butterfly valve, in particularly a kind of equipment pipe that is applicable to aggressive mediums such as industry acid, alkali, salt such as oil, chemical industry, metallurgy, chemical fertilizer and the media processing apparatus as closed circuit and regulate a kind of butterfly valve that flow uses.
At present, the equipment pipe and the media processing apparatus that are used for aggressive mediums such as industry acid, alkali, salt such as oil, chemical industry, metallurgy, chemical fertilizer are monolithic construction as butterfly valve body closed circuit and that the adjusting flow uses, the butterfly valve valve rod runs through the butterfly plate center and is connected with pin with butterfly plate, and there is the cylindrical body of projection at the butterfly plate center, the butterfly valve seal seat is the straight barrel type ring sealing base in addition, adopts plane sealing with the butterfly plate two ends, and this butterfly valve is the installation, maintenance trouble not only, and sealing effect is bad, the cost height.
The purpose of this utility model provides a kind of installation, maintenance convenience, good sealing effect and causes the corrosion-resistant butterfly valve of low wafer type.
The purpose of this utility model is achieved in that it comprises valve body, last lower valve rod, sealing seat, valve plate up and down, it is characterized in that valve body is installed in the valve body by the affixed sealing seat that makes of bolt up and down, valve plate is installed in the sealing seat, is connected with the valve plate two ends by last lower valve rod.
The utility model has the advantages that: novel structure, good sealing effect, installation, maintenance is convenient, and cost is low, the manufacturing efficiency height.
Do embodiment's explanation below in conjunction with accompanying drawing.
Fig. 1 is a plan view of the present utility model.
Fig. 2 is the side view of Fig. 1.
By Fig. 1-2 as can be known, upper valve body 1 and following valve body 2 are affixed by bolt 10, form body cavity, sealing seat 4 is installed in the body cavity, valve plate 7 is installed in the sealing seat 4, valve plate becomes planar substantially, can save material, and fluid resistance is little, by lower valve rod on the two-part 3 and 8 and valve plate be connected with square hole, sealing surface of valve plate is that ball face sealing and valve seat 4 inner chambers form sealing pair, and sealing seat inner edge two ends form boss 5 and form a sealing pair with valve plate 7 two-part spheres 6, and seal boss 5 is narrower than the sealing sphere 6 on the valve plate, no matter be in opening state, or closed condition, boss all can keep tight contact the, good sealing effect with sphere.
Claims (2)
1, the corrosion-resistant butterfly valve of a kind of wafer type, it comprises valve body, last lower valve rod, sealing seat, valve plate up and down, it is characterized in that valve body is installed in the valve body by the affixed sealing seat that makes of bolt up and down, and valve plate is installed in the sealing seat, is connected with the valve plate two ends by last lower valve rod.
