Abstract
The utility model relates to a V-shaped ball valve, which comprises a valve body, a valve seat, a valve stem, a sphere, a transmission mechanism, a sealing part and an installation part, wherein the valve seat is a metal valve seat structure, substantially, a soft sealing valve seat is further arranged on the external side of the metal valve seat, the soft sealing valve seat not only has the advantages of auxiliary seal, but also is capable of cleaning fouling and slag materials on the surface of the sphere, thereby preventing wearing the sealing surface of the sphere and the sealing surface of the metal valve seat. The utility model has the advantages of reliable sealing performance, long service life, and is suitable to conditions with media such as micro grain, powder, ash and slurry and the like.
Description
Technical field
The utility model relates to a kind of ball valve, specifically about a kind of V-arrangement ball valve.
Background technique
Ball valve is simple in structure because of it, characteristics such as flow resistance is little during unlatching, and be widely used in various medium operating modes.The structure of ball valve generally comprises valve body, valve gap, valve seat, valve rod, spheroid, driving mechanism and Sealing and assembling set, and valve seat is by structural types such as floating valve seat and fixed valve bases, and its sealing surface of seat and ball seal face cooperatively interact, and constitutes ball valve sealing pair.Yet, the subject matter of ball valve is at present: valve in use, dirt that spherome surface is piled up gradually and slag charge, can produce wearing and tearing to sealing surface of seat, when particularly valve is used in the operating mode of media such as band molecule, powder, lime-ash, slurry, this wearing and tearing are particularly serious, thereby influenced the sealability and the working life of valve.
The model utility content
The purpose of this utility model is the problem that exists at prior art, provides a kind of and can effectively prevent ball seal face and valve base sealing surface wear, and sealability is reliable, the V-arrangement double-seal ball valve of long service life.
The technological scheme that realizes the utility model purpose comprises valve body, valve seat, valve rod, spheroid, driving mechanism and Sealing and assembling set, and valve seat is the metal seat valve structure, mainly is also to be provided with a soft seal valve seat in the metal seat valve outside.
In above scheme, the soft seal valve seat is fitted on the valve body by gland.
The utility model beneficial effect compared with prior art is also to be provided with a soft seal valve seat in the metal seat valve outside, this soft seal valve seat is except that having auxiliary seal, can also remove the dirt and the slag charge of spherome surface, prevent ball seal face and metal seat valve sealing surface wear, its sealability is reliable, long service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an A place structure enlarged view among Fig. 1.
Embodiment
V-arrangement double-seal ball valve as shown in Figure 1, comprise valve body 1, valve seat 2, valve rod 3, spheroid 4, driving mechanism and Sealing and assembling set, valve seat 2 is floating type metal seat valve structure, spheroid 4 is the V-arrangement sphere structure, the surface of metal seat valve is shaped on the sealing surface that cooperatively interacts with the V-arrangement spherome surface, be provided with seal ring 6 between metal seat valve and the valve body 1, sealing circle 6 is pressed between valve body 1 and the metal seat valve by spring seat 7 and spring 8, also is provided with a soft seal valve seat 5 in the metal seat valve outside.This soft seal valve seat 5 is fitted on the valve body 1 by gland 9, and is shaped on the sealing surface that cooperatively interacts between spheroid 4 surfaces.
