Abstract
The invention is a device for releasing and disconnecting a fitting body off of a pipe, which is held with a gripping ring that holds the pipe in fixed position inside the fitting body. Particularly, the device is integrated into valves for disconnecting domestic valves installed over pipes, which are fixed to and extending out of walls. The essential parts of the device are a nut, a pushing sleeve matching into the nut and one or more spiral tracks that couple with bump(s)/ball(s) on the surfaces of the nut and sleeve. This coupling enables radial movement of the nut in a defined spiral forward direction over the fitting body and pushes the sleeve into the fitting body for releasing the pipe off of the gripping ring.
Claims22
A releasing device for disconnecting a fitting body off of a pipe, said releasing device comprising:
- one or more spiral tracks;
- at least one bump/ball;
- a nut;
- and
- a pushing sleeve with a conical tapered shape,
- wherein coupling of the bump(s)/ball(s) with the spiral track(s) enables radial movement of the nut in a defined spiral forward direction over the fitting body and pushing of the pushing sleeve into the fitting body for releasing a pipe held inside off of a gripper ring that holds the pipe in fixed position inside the fitting body.
An assembly for disconnecting a fitting body water piping off of a pipe, said assembly comprising:
- a releasing device for disconnecting a fitting body off of a pipe, said releasing device comprising:
- one or more spiral tracks;
- at least one bump/ball;
- a nut;
- and
- a pushing sleeve with a conical tapered shape,
- a fitting body;
- a conical ring for placing a gripper ring in fixed position;
- a gripper ring for locking the pipe in fixed position within the fitting body, the gripper ring comprising teeth extending radially in inclined angle towards the center of the gripper ring and frictionally holding the pipe in its fixed position;
- a sealing ring for a water-tight seal between the pipe and fitting body;
- and
- a locking ring configured for holding the assembly of rings including the gripper ring in fixed axial position;
- and
- a sealing ring for sealing a gap between the receiving end of the fitting body and the locking ring,
- wherein the bump(s)/ball(s) are located on the nut and the spiral track(s) are located on the receiving end of the fitting body,
- wherein the bump(s)/ball(s) and spiral tracks are configured to couple with each other to enable spiral forward movement of the releasing device over or in the fitting body,
- wherein coupling of the bump(s)/ball(s) with the spiral track(s) enables radial movement of the nut in a defined spiral forward direction over the fitting body and pushing of the pushing sleeve into the fitting body for releasing a pipe held inside off of a gripper ring that holds the pipe in fixed position inside the fitting body.
An assembly for disconnecting a fitting body water piping off of a pipe, said assembly comprising:
- a releasing device for disconnecting a fitting body off of a pipe, said releasing device comprising:
- one or more spiral tracks;
- at least one bump;
- a nut;
- and
- a pushing sleeve with a conical tapered shape,
- a fitting body;
- a gripper ring for locking the pipe in fixed axial position within the fitting body, the gripper ring comprising teeth extending radially in inclined angle towards the center of the gripper ring and frictionally holding the pipe in its fixed position;
- a sealing ring for a water-tight seal between the pipe and fitting body;
- and
- a conical ring configured for accommodating the gripper ring while allowing the gripper ring to rotate freely and allowing the gripper ring teeth to bend radially,
- wherein the bump(s)/ball(s) are located on the fitting body and the spiral track(s) are located on the nut,
- wherein the bump(s)/ball(s) are configured to couple with each other to enable spiral forward movement of the releasing device over or in the fitting body,
- wherein coupling of the bump(s)/ball(s) with the spiral track(s) enables radial movement of the nut in a defined spiral forward direction over the fitting body and pushing of the pushing sleeve into the fitting body for releasing a pipe held inside off of a gripper ring that holds the pipe in fixed position inside the fitting body.
