Abstract
The utility model discloses a loose joint intubation ball valve, which comprises a valve body with two ports, a valve core which is arranged in the valve body and provided with a liquid channel, and a valve rod one end of which extends into the valve body and is connected with the valve core and the other end of which is provided with a handle, wherein the first port of the valve body is connected with a tubular loose joint connecting piece; a loose joint nut with an inner flanging is sleeved outside the loose joint connecting piece; one end of the loose joint connecting piece, which is far away from the valve body, is provided with an outer flanging which is used for being matched with the inner flanging and limiting the limiting position of the loose joint nut; the loose joint connecting piece is connected with the valve body by a thread; one end of the loose joint connecting piece, which is connected with the valve body, is provided with an external thread; the first port of the valve body is provided with an internal thread matched with the external thread; the second port of the valve body is connected with a tubular joint; and the outer wall of the tubular joint is provided with a plurality of annular bosses wound in the axis direction. Compared with the prior art, the loose joint nut of the loose joint intubation ball valve can not be lost due to being limited by the flangings and is convenient for transportation and installation, and rubber gaskets are not needed at joints, thereby reducing the water leakage chances.
Description
Technical field
The utility model relates to the water heating fittings field, especially relates to a kind of loose joint ball valve of control media circulation.
Background technique
Ball valve is widely used in the water heating fittings field, basic principle is exactly the circulation that rotation has the spool of inner chamber to come control media, ball valve of the prior art comprises that an outlet is connected MEDIA FLOW respectively with an import and threads a pipe, handle links to each other with spool by valve rod, rotatable handle 0-90 degree can be realized the switching of valve.When handle rotated to the position that ball valve opens, medium circulated by the inner chamber of spool.When handle rotated to the position of closing, medium did not circulate.Owing to when ball valve and MEDIA FLOW are threaded a pipe and be connected, need fixed by nut, in transporting installation process, the nut that matches is lost easily.Use rubber gasket if connect, repeatedly the immersion of extruding or medium also causes aging easily.
Summary of the invention
The utility model provides a kind of loose joint intubate ball valve.
For achieving the above object, the utility model adopts following technological scheme:
A kind of loose joint intubate ball valve, comprise valve body, be positioned at a spool and the end that valve body has fluid passage and stretch into the valve rod that valve body links to each other with spool, the other end is provided with handle with two ports, first port of described valve body is connected with the loose joint link of tubulose, the loose joint nut of loose joint link overcoat one band in-flanges, the loose joint link has away from an end of valve body and is used for cooperating with described in-flanges, is used to limit the flanging of the limit position of loose joint nut.
As preferably, described loose joint link and valve body are by being threaded.
As preferably, the end that described loose joint link links to each other with valve body is provided with outside thread, and first port of described valve body has the internal thread that matches with this outside thread.
As preferably, second port of described valve body is connected with tubular configured joint, and the outer wall of tubular configured joint is provided with some annular protrusions around axial direction.
The utility model is compared with prior art, and the loose joint nut can not lost because there is flange spacing, is convenient to transportation, installs, and the chance of leaking has been reduced without rubber gasket in the joint.
