Embodiment Construction

[0016] figure 1 , 2 An externally sealed fluid pipe connection device is given, including a plug sleeve 1 , a push tooth ring 2 , an internal tooth snap ring 3 , a supporting ring 4 , a sealing ring 5 and a pipe joint 6 . Put the plug sleeve 1 into the pipe joint 6, press it with a closing tool or tighten it in other ways, so that the parts such as the push tooth ring 2, the inner tooth snap ring 3, the supporting ring 4 and the sealing ring 5 are wrapped on the pipe joint 6 and Inside the plug sleeve 1, the internal tooth snap ring 3 is placed on the supporting ring 4, and the sealing ring 5 is located below the supporting ring 4. There is a sliding contact between the push gear ring 2 and the plug sleeve 1 . In the pipeline connection state, the top of the push gear ring 2 is basically flush with the plug sleeve 1, as figure 2 shown. The top of push tooth ring 2 also can shrink in the plug sleeve 1.

Abstract

The invention provides a fluid pipe connection device, aiming to solve the problems that the pipe demolition is troublesome and the top part of the pushing gear ring can be easily worn and damaged. The fluid pipe connection device comprises a pipe connector, and an inner gear clamping ring and a pushing gear ring are arranged in the pipe connector and a plug sleeve via the plug sleeve arranged fixedly on the pipe connector. When a pipe is butted, the pipe penetrates through the plug sleeve, the pushing gear ring and the inner gear clamping ring, and the wall of the pipe is tightly clamped by the inner gear clamping ring; and when the pipe is removed, and an inner gear is pushed by the pushing gear ring along the pipe insertion direction so that the wall of the pipe is not clamped by the inner gear clamping ring. The fluid pipe connection device is characterized in that the pushing gear ring and the plug sleeve are contacted in a sliding way; and the top end of the pushing gear ring is basically flush with the plug sleeve or is contracted into the plug sleeve when the pipe is butted. The invention also provides a supporting pipe demolition tool, which comprises a handle, the handle is connected with an ejection block, and the ejection block can extend into a clearance between the plug sleeve and the wall of the pipe to push the pushing gear ring.

Description

technical field [0001] The invention relates to a fluid pipe connection device and a matched pipe removal tool thereof. Background technique [0002] Chinese patent No. 200310101202.7 (hereinafter referred to as the reference document) with the authorized announcement number CN1324258C describes a fluid pipe connection device for guiding the flow of fluids such as water or gas (the reference document is referred to as "water or steam pipe connection device"), including A pipe joint and a plug sleeve that can be fastened on the pipe joint, and the plug sleeve is sleeved outside the pipe wall after being passed through by the pipe. There are internal tooth snap rings (referred to as "internal tooth locking ring 3" in the reference document) and push tooth rings (referred to as "opening and closing ring 2" in the reference document) installed in the pipe joint and the plug sleeve. During the connection, the pipe passes through the plug sleeve and the push tooth ring, and then...
