Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1 and 2, the novel floating safety valve structure of the present embodiment includes a valve housing 9, a valve seat 3 is installed in an inner hole of the valve housing 9 in a matching manner, an outer end surface of the valve seat 3 is fixed by a pressing screw sleeve 2 and a first lock nut 1, a slide bar 6 is installed at an inner end surface of the valve seat 3, a first steel ball 4 is installed at one end of the slide bar 6 through a pad 5, the first steel ball 4 is matched with an opening formed in the inner valve surface of the valve seat 3, and a second steel ball 7 is installed at the other end of the slide bar 6; an ejector rod 8 is further installed in an inner hole of the valve casing 9, the cross section of the ejector rod 8 is of a T-shaped structure, the end of the ejector rod 8 is in butt joint with the second steel ball 7, the ejector rod 8 is sleeved with a disc spring 10, and the tail portion of the ejector rod 8 is fixed with the valve casing 9 through an adjusting threaded sleeve 11 and a second locking nut 12.
As shown in fig. 3, the slide bar 6 has the following structure: the sliding rod comprises a sliding rod body 602 and a cylindrical structure of the sliding rod body 602, wherein one end of the sliding rod body 602 is provided with a circular groove 601 for mounting a first steel ball 4 and a pad 5, the inner bottom surface of the circular groove 601 is matched with the pad 5, the other end of the sliding rod body 602 is provided with a conical groove 603 for mounting a second steel ball 7, and the conical groove 603 is tightly matched with the second steel ball 7.
As shown in fig. 4, a tapered hole 501 is formed in the middle of the pad 5, and the tapered hole 501 is engaged with the first steel ball 4.
The middle part of the end head of the ejector rod 8 is provided with a bulge, a V-shaped structure is arranged at the bulge, and the V-shaped structure is matched with the second steel ball 7.
The utility model discloses with the case in the cone valve structure among the prior art, after adding the steel ball respectively at both ends, the case becomes a slide bar 6 promptly.
The first steel ball 4 is free to form a line seal with the valve seat 3 when the belleville spring 10 is compressed. When the safety valve is opened, the sliding rod 6 becomes floating due to the existence of the first steel ball 4 and the second steel ball 7, and no other clamping occurs; when the valve is closed, the first steel ball 4 can automatically return to the original sealing position of the valve seat 3 to form a good sealing state.
In the actual use process, as shown in fig. 1, the sliding rod 6 is in an open state at this time, and if the sliding rod 6 needs to be closed, only the second lock nut 12 needs to be loosened, the adjusting screw sleeve 11 is screwed, the disk spring 10 is pressed, the ejector rod 8 pushes the second steel ball 7 to move leftward (the position shown in the figure is leftward), so that the sliding rod 6 is driven to move leftward until the first steel ball 4 contacts the valve seat 3 to form a seal, and then the second lock nut 12 is screwed.
The utility model adds steel balls at two ends of the slide bar 6, and the steel ball at one side is matched with the valve seat 3 to play the role of a valve core; the steel ball at the other end is connected with the ejector rod 8 and bears the spring force, so that the slide rod 6 finally floats, and the safety valve is conveniently opened and closed by screwing the adjusting screw sleeve 11.
