Description
Technical field
The utility model relates to a kind of ball valve, particularly relates to a kind of combustion gas all-welded ball valve.
Background technique
Ball valve is the first-selected valve on Gao Long-distance Transmission Pipeline, because Gao Long-distance Transmission Pipeline is in field, require very high to working life of valve and sealability, the structure of existing ball valve is generally by valve body, valve seat, valve rod, spheroid forms, due to ball valve Long-Time Service outdoor occasion in the wild, valve body generally adopts all-welded structure, can prevent medium from leaking outside, its major defect requires high to valve body welding technique, the heat of high temperature that welding produces easily affects the sealability of sealing surface of seat, and can not on-line maintenance after spheroid and valve seat damage, sealability is unreliable, maintenance is inconvenient.
Model utility content
Based on the problems referred to above, the utility model object is to provide a kind of combustion gas all-welded ball valve, has comparatively high sealing intensity.
For above problem, provide following technological scheme: combustion gas all-welded ball valve, comprise valve body, valve seat, spheroid and valve rod, medium input is provided with at the two ends of valve body, output tube, described medium input, being fixedly connected by welding of output tube and valve seat, ball valve and medium input, valve seat insert is disposed with between output tube, metallic sheath and disc spring, it is characterized in that: described metallic sheath comprises the base portion that belled part and diameter are greater than belled part, described valve seat insert is socketed on the belled part of metallic sheath and its end is butted on base portion, end face corresponding with valve seat insert in described base portion is laterally, input to medium, the cone structure that output tube outer end extends, the end of valve seat insert is corresponding with this cone structure to be arranged, described valve seat insert is provided with the elastomeric seal portions that elasticity is butted on base portion, elastomeric seal portions can be arranged relative to valve seat insert in elasticity activity, valve seat insert is provided with the groove structure corresponding with elastomeric seal portions, the elastic component making elastomeric seal portions elasticity be butted on base portion is provided with in groove structure.
Pass through said structure, under pressure medium, spheroid extrudes valve seat insert, the base portion of cone structure and the setting of valve seat insert, valve seat insert can be strengthened and medium inputs, sealing intensity between output tube, elastic component is coordinated to extrude the elasticity of elastomeric seal portions, can the sealing of maximized guarantee valve body.
The utility model is set to further, and described metallic sheath and medium input, be respectively equipped with O-ring seal between output tube inwall, and this structure can ensure the sealing of valve body further.
The utility model is set to further, described elastic component be positioned at groove structure loop configuration and its cross section is U-shaped, this U-shaped structure elasticity can be butted on elastomeric seal portions, realizes the sealing of elastomeric seal portions to gap location.
