Control valve connector

Abstract

A control valve connector has a valve body, a connecting member, at least two sealing rings and a positioning nut. The valve body has a first connecting opening and at least two second connecting openings, an outer edge of the second connecting opening provided with a threaded section. The first connecting opening is configured for coupling with the positioning nut, and the connecting member is a tubal body having a through aperture and a spherical end.

Claims

1. A control valve connector comprising a valve body, a connecting member, at least two sealing rings and a positioning nut, wherein the valve body has a first connecting opening and at least two second connecting openings, an outer edge of the second connecting opening provided with a threaded section, the first connecting opening configured for coupling with the positioning nut, the connecting member being a tubal body having a through aperture and a spherical end, characterized in that: the first connecting opening of the valve body comprises a first aperture and a second aperture connected with each other, the first aperture disposed in a sidewall of the valve body and larger than the second aperture, the second aperture provided with a threaded section for engaging with the connecting member; another end of the connecting member comprising a wide diameter section and a narrow diameter section, the wide diameter section is provided with at least two circular grooves for accepting the sealing rings and adjacent to the spherical end, and the narrow diameter section is provided with a threaded section; wherein the narrow diameter section of the connecting member is inserted into the positioning nut and then locked with the second aperture of the valve body, such that the wide diameter section presses against the threaded section of the second aperture, and the sealing ring jacketed on the wide diameter section pushes against an inner wall of the first aperture.

2. The control valve connector as claimed in claim 1, wherein each second connecting openings of the valve body has a different angle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(8) First, please refer to FIGS. 1-6. A control valve connector comprises a valve body 10, a connecting member 20, at least two sealing rings 30 and a positioning nut 40. The valve body 10 has a first connecting opening 11 and several second connecting openings 12, an outer edge of the second connecting opening 12 is provided with a threaded section. The first connecting opening 11 is configured for coupling with a positioning nut 40 to be assembled at an opening 51 of a water pipe 50. Each second connecting openings 12 of the valve body 10 has a different angle. The connecting member 20 is a tubal body having a through aperture 22 and a spherical end 21. The first connecting opening 11 of the valve body 10 comprises a first aperture 111 and a second aperture 112. The first aperture 111 is disposed in a sidewall of the valve body 10, and is larger than the second aperture 112. The second aperture 112 is provided with a threaded section for engaging with the connecting member 20. Another end of the connecting member 20 opposite the spherical end 21 has a wider diameter section 23 and a narrower diameter section 25. The wider diameter section 23 is provided with at least two circular grooves for accepting the sealing rings 30 and is adjacent to the sphere end 21. The narrower diameter section 25 is provided with a threaded section. When the narrower diameter section 25 of the connecting member 20 member is inserted into the positioning nut 40 and then locked with the second aperture 112 of the valve body 10, the wider diameter section 23 presses against the threaded section of the second aperture 112 to create a first seal. Then the sealing ring 30 jacketed on the wide diameter section 23 pushes against an inner wall of the first aperture 111 which provides another seal.

(9) When the connector member 20 and the valve body 10 are assembled together, the protrusion of the wider diameter section 23 can prevent the anoxic glue applied to the narrower diameter section 25 from penetrating into the circular groove 24 and causing the sealing ring 30 to harden.

(10) With the structure of the above embodiment, the following benefits can be obtained: when the assembly of the second aperture portion 112, the narrower diameter section 25, the first aperture portion 111, and the wider diameter section 23 is combined with the at least two sealing rings 30, multiple leak-proof effects on the assembly structure of the control valve is created, so that the use of the control valve assembly structure can avoid water leakage at the valve body 10 and the connector member 20.

(11) Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of invention as hereinafter claimed.
