초록 ▼

A pipe coupling for a stainless steel well casing includes a square threaded male member which is received within a square threaded female member so that the coupling is initially loose. O-ring seals are provided to prevent the fluid being pumped from corroding threaded portions of the male and female members. Each member has a shoulder which is abutted by the end of the other member in order to lock the members in rigid relationship.

대표청구항 ▼

A pipe coupling for joining first and second pipes along a common axis, the pipe coupling comprising: a tubular male member having first and second ends and a tubular female member having first and second ends wherein the first ends of the male and female members abut the pipes while the second end of the male member is received within a portion of the female member and the second end of the female member extends over a portion of the male member; means for fixing the first ends of the male and female members to opposed ends of the first and second pipes, respectively; the male member having a first portion having an outside diameter equal to that of the first pipe and a second portion having a reduced outside diameter and joining the first portion at a first radial shoulder, the reduced diameter portion having a first unthreaded cylindrical surface adjacent the first shoulder, the first cylindrical surface having a groove therein spaced from the first radial shoulder; a threaded section extending from the first cylindrical section, the threaded section having threads of a square cross-section; a second cylindrical surface extending from the threaded section to the second end of the male member, the second end of the male member presenting a radial surface perpendicular to the axis of the coupling; the male member having a constant internal diameter over substantially the entire length thereof except for a frusto-conical section adjacent the first end thereof; the female member having a constant outside diameter over the entire length thereof, the outside diameter of the female member being equal to the outside diameter of the first portion of the male member with the second end of the female member being a radial surface normal to the axis of the female member; the female member having a first portion with an internal diameter equal to that of the internal diameter of the male member, said first portion joining the first end of the female member with a frusto-conical surface; the female member having a second portion of a diameter less than the first portion and greater than the second portion of the male member, the second portion of the female member having a cylindrical surface adjacent a second radial shoulder, the cylindrical surface of the female member having a circular groove therein spaced from the second radial shoulder; a threaded section extending from the first cylindrical portion, the threaded section having square threads thereon which complement the square threads of the threaded section on the male member; a second cylindrical surface between the threaded section and the second end of the female member, the second cylindrical surface having an internal diameter greater than the internal diameter of the first cylindrical surface and slightly greater than the first cylindrical surface on the male member; the distance between the shoulders and second ends of the male and female members being identical; and O-ring seals disposed in the grooves in the first cylindrical surfaces of the male and female members, whereby when the threads are engaged and the male and female members are screwed together, the O-rings effect seals with the second cylindrical surfaces of the members while the joint between the members of the coupling is rigidified upon engagement of the second ends of the male and female members with the shoulders of the female and male members.
