Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

As shown in fig. 1 and 2, the swing valve of the present invention includes a valve body 10, a connecting rod 20 rotatably connected to the valve body 10, and a valve cover 30 disposed on the connecting rod 20.

The valve body 10 has an inlet channel 11 and an outlet channel 12, a medium introduced from the inlet channel 11 can push the valve cover 30 open, so that the inlet channel 11 is communicated with the outlet channel 12, when no medium is introduced into the swing valve, the valve cover 30 can block the inlet channel 11 of the valve body 10 under the action of gravity, and when the medium is introduced into the inlet channel 11 of the swing valve, the valve cover 30 can push the valve cover 30 under the pressure action of the medium, so that the valve cover 30 drives the connecting rod 20 to rotate on the valve body 10, thereby achieving the conduction of the medium in the swing valve.

In the present embodiment, the sliding sleeve 40 is movably connected to the inlet channel 11 of the valve body 10, the medium introduced from the inlet channel 11 can drive the sliding sleeve 40 to partially extend out of the inlet channel 11, and when the valve cover 30 falls down onto the inlet channel 11 under the action of gravity, the valve cover 30 can impact the sliding sleeve 40 to restore the sliding sleeve 40. That is to say, after the medium in the swing valve is cut off, the valve cover 30 firstly impacts the sliding sleeve 40 in the falling process, and then abuts against the valve body 10, and the noise reduction effect is realized by utilizing the structural characteristics of the sliding sleeve 40.

Specifically, the sliding sleeve 40 of the embodiment includes a sleeve 41 and a stopper 42 disposed at one end of the sleeve 41, an outer cylinder wall of the sleeve 41 fits a channel wall of the inlet channel 11, and the stopper 42 can abut against an inlet edge 111 of the inlet channel 11 to limit the sliding sleeve 40 from moving continuously toward the outlet channel 12, so as to specifically realize the structural arrangement of the sliding sleeve 40, and the outer cylinder wall of the sleeve 41 on the sliding sleeve 40 fits a channel wall of the inlet channel 11, so as to guide the movement of the sliding sleeve 40 in the inlet channel 11 of the valve body 10, thereby ensuring the stability of the movement of the sliding sleeve 40 in the inlet channel 11.

In the present embodiment, the spacer ring 50 is fixedly connected to the inlet edge 111 of the inlet channel 11 of the present embodiment, and the flange 60 is used for abutting and limiting, and the stop 42 of the sliding sleeve 40 is disposed inside the spacer ring 50 and can move back and forth between the flange 60 and the inlet edge 111, so as to specifically realize the bidirectional limiting of the movement of the sliding sleeve 40, and ensure that the sliding sleeve 40 returns to the initial position under the action of the valve cover 30.

Further, the flange 60, the spacer ring 50 and the inlet edge 111 of the present embodiment are connected and fixed by bolts (not shown), so that the flange 60 limits and fixes the spacer ring 50 on the inlet edge 111 of the valve body 10.

In addition, it should be noted that the sliding sleeve 40 of the present embodiment is configured as a rubber sleeve, so as to facilitate the production and preparation of the sliding sleeve 40.

To sum up, the utility model discloses a swing valve simple structure sets up through the reasonable structure of sliding sleeve for this swing valve can partially stretch out access way under the promotion of medium when switching on the medium, and the sliding sleeve can strike the sliding sleeve when the valve gap whereabouts like this, utilizes the structural feature of sliding sleeve, avoids the direct striking valve body of valve gap, and then plays the noise that reduces this swing valve during operation.
