Abstract
The utility model provides a novel rolling steel ring type seal face of a butterfly valve, which is simple and reasonable in structure and good in seal performance and is formed by a valve body (1), a valve body seal ring (2), a valve body seal steel ring (3), a valve plate seal ring (4), a valve plate (5) and a pressure ring (6). The novel rolling steel ring type seal face of the butterfly valve is characterized in that a groove is arranged on a valve body seal face, a valve body seal ring (2) is arranged in the groove, the valve body seal steel ring (3) is covered on the valve body seal face, and the top end of the lower protrusion portion of the valve plate seal ring (4) is connected with the valve body seal steel ring (3). The valve body seal steel ring (3) adopts a whole 316L steel ring and is directly rolled on the seal face by a special rolling device, and the inside of the valve body seal steel ring is provided with the valve body seal ring (2) made of rubber so as to ensure non-leakage in use. The surface of a stainless steel valve seat after rolling forming is smooth and flat. The novel rolling steel ring type seal face of the butterfly valve is stable and firm, strong in corrosion resistance, high in coaxiality, low in surface roughness and good in seal match with the valve plate seal ring (4) and prolongs service life of the valve.
Description
Technical field
The utility model relates to a kind of sealing surface of butterfly valve, relates in particular to a kind of novel butterfly valve roll extrusion endless-ringlock sealing surface.
Background technique
Valve is the control gear of fluid circuit, and its fundamental function is the medium that switches on or off pipeline, the flow of control media, pressure and circulating direction, the normal operation of protective tube pipeline equipment.Butterfly valve is that closure member is a kind of valve of disk, and main rising cut off and throttling action on pipeline.Butterfly valve compare with gate valve have the switching time short, operational torque is little, installing space is little and lightweight advantage, and is prone to and various combination of drive means, has favorable durability and reliability.Existing butterfly valve seal face uses the structure of brush plating nickel phosphor alloy, and in use for some time, easy-to-rust comes off, and the coarse valve seat of corrosion can be dampened the butterfly plate seal ring very soon, causes leakage, scraps, and has influenced the working life of valve greatly.
Summary of the invention
In order to solve the problems of the technologies described above; The utility model provides a kind of novel butterfly valve roll extrusion endless-ringlock sealing surface of simple and reasonable, good seal performance; Constitute by valve body (1), valve seals (2), valve seal steel loop (3), valve plate seal ring (4), valve plate (5), pressure ring (6), it is characterized in that valve body sealing surface is provided with groove, be provided with valve seals in the groove; The valve seal steel loop covers on the valve body sealing surface; The protuberance top connects with the valve seal steel loop under the valve plate seal ring, and valve plate seal ring right side connects with valve plate, and the left side connects with pressure ring.
The beneficial effect of the utility model is: the valve seal steel loop adopts whole piece 316L steel loop, and on sealing surface, its inside is furnished with valve seals by the direct roll extrusion of special rolling device, and valve seals is a rubber ring, and is non-leakage in guaranteeing to use.Stainless Steel Valve seating face smooth after the roll forming, firmly firm, erosion resistance is strong, and coaxality is high, surface roughness is low, with being sealed and matched of valve plate seal ring, has prolonged the working life of valve.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
According to shown in Figure 1, valve body (1) sealing surface is provided with groove, is provided with valve seals (2) in the groove; Valve seals (2) is a rubber ring, and valve seal steel loop (3) adopts whole piece 316L steel loop, by the direct roll extrusion of special rolling device on sealing surface; Smooth surface is smooth, and anti-corrosion capacity is strong; Valve plate seal ring (4) is a rubber ring, and in the middle of pressure ring (6) and valve plate (5), it contacts with valve seal steel loop (3) on protuberance top down, and valve plate seal ring (4) cooperates with valve seal steel loop (3), good sealing effect.
Claims (1)
