A ring type anti-freezing stainless steel pipe fitting

Abstract

The invention relates to the technical field of stainless steel pipe fittings, in particular to a ring clamp type anti-freezing stainless steel pipe fitting, including a connector and a connecting pipe. The connector includes a limit ring, a No. 1 inner snap ring, a No. 2 inner snap ring and an outer snap ring. The connecting pipe includes a flow end, an outlet end and a connecting end. The number of outlet ends is 2, and the connecting end is welded to the connecting head; the second internal snap ring provides a buffer space for the connecting pipe inserted into the connecting head, which reduces the difficulty of inserting the connecting pipe and is easy to weld; The No. 1 inner snap ring and the No. 2 inner snap ring provide a buffer space for the connector to shrink inward, and the outer snap ring provides a buffer space for the connecting pipe to expand outward, so as to prevent the connector and the connecting pipe from freezing off; the connecting pipe and the connecting pipe of the present invention The connection effect and sealing between the connectors are more stable and reliable, and the connecting pipe is easier to enter the connectors, which reduces the difficulty of welding and prevents the connectors from freezing off.

Description

technical field [0001] The invention relates to the technical field of stainless steel pipe fittings, in particular to a ring clamp type anti-freezing and detachable stainless steel pipe fitting. Background technique [0002] There is a common technical defect in the existing pipe fitting socketing methods, that is, the anti-slip performance of the connected connecting pipe and the connecting head is not perfect. The head and the connecting pipe are easy to freeze off, which affects the sealing of the connecting head and the connecting pipe, and the fluid is easy to overflow, which brings great difficulties to the construction and increases the cost of maintenance. Chinese patent CN 107795782A discloses a connection structure of an anti-off type plug-in pipe. The two ends of the pipe body on the pipe fitting are respectively provided with a socket and a socket. The inner wall of the socket is set with a limit groove in the radial direction, the limit groove divides the chut...

[0002] There is a common technical defect in the existing pipe fitting socketing methods, that is, the anti-slip performance of the connected connecting pipe and the connecting head is not perfect. The head and the connecting pipe are easy to freeze off, which affects the sealing performance of the connecting head and the connecting pipe, and the fluid is easy to overflow, which brings great difficulties to the construction and increases the cost of maintenance

Chinese patent CN 107795782A discloses a connection structure of an anti-off type plug-in pipe. The two ends of the pipe body on the pipe fitting are respectively provided with a socket and a socket. The inner wall of the socket is set with a limit groove in the radial direction, the limit groove divides the chute into two parts, and the limit groove and the chute are connected, and the outer wall of the socket is provided with two limit blocks that are slidingly matched with the chute , the limit block can be clamped in the limit groove; the anti-off type plug-in pipe connection structure, when connecting the pipe fittings, the socket of one pipe fitting to be connected is opposite to the socket of the other pipe fitting to be connected, and the socket The limit block on the socket is aligned with the chute on the socket and slides into the connection. When it reaches the position of the limit groove, the relative rotation between the two pipes occurs, so that the limit block on the socket is snapped to the limit on the socket. The connection between two pipe fittings can be completed in the bit groove; but it is difficult to ensure the tightness of the pipe fittings only through the sealing ring, and the sealing ring will increase the frictional force of relative rotation between the two pipe fittings, increasing the difficulty of connection
