Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a ball valve capable of draining sewage. Background Art

[0002] In the transportation of liquid media, in order to facilitate the on-off control of the liquid media during transmission, a valve for control is very necessary. A ball valve is a valve with a spherical valve core.

[0003] Patent No. CN215980930U discloses a ball valve. The ball valve includes a valve body, a valve core, an anti-backflow assembly and an adjusting baffle. The valve core is rotatably and limitably arranged in the valve cavity of the valve body. The valve core is provided with a liquid permeable hole, which can be connected with the liquid inlet and the liquid outlet of the valve body respectively. The anti-backflow assembly includes an anti-backflow plate. The anti-backflow plate can be arranged on the liquid inlet in a unidirectional manner along the flow direction of the medium. The adjusting baffle is provided with a micropore group and a coarse hole. Along the rotation direction of the valve core, the micropore group is located upstream of the coarse hole. Multiple groups of micropore groups are coaxially spaced. Along the edge of the adjusting baffle toward the center, the aperture of the micropore group gradually increases, and the aperture of the coarse hole is larger than the maximum aperture of the micropore group. The setting of the adjusting baffle can prevent the ball valve from being damaged by a sharp increase in the medium. The setting of the anti-backflow assembly can prevent the backflow of the medium in the ball valve and extend the service life of the ball valve.

[0004] The conventional ball valve has the following disadvantages: 1. It does not have a structure for draining waste, and cannot conveniently discharge the accumulated waste and impurities in the valve body as required. Therefore, we propose a ball valve for draining waste. Summary of the invention

[0005] The main purpose of the utility model is to provide a ball valve capable of draining sewage, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A ball valve capable of draining sewage comprises a valve body, a connecting flange, a spherical valve core, a rotating rod and a rotating handle, wherein the inner wall of the valve body is provided with grooves near both ends of the spherical valve core, and sealing rings and filter screens are respectively provided in two groups of the grooves, a threaded groove is provided at the top of the valve body near one end of the filter screen, a water pipe joint is provided on the outside of the threaded groove, a sewage pipe is provided at the bottom of the valve body near one end of the filter screen through a fixing hole, an electromagnetic valve is provided on the sewage pipe, a blocking groove is provided at the inner wall of the valve body near the sewage pipe and one end of the threaded groove, a vertical plate is welded at one end of the top of the valve body, a servo electric cylinder is provided on one side of the top of the vertical plate through a fixing seat, the power output end of the servo electric cylinder is connected to a blocking plate, and the bottom end of the blocking plate is located in the blocking groove.

[0008] Furthermore, a rotary sealing plug is arranged in the thread groove via an internal thread.

[0009] Furthermore, connecting flanges are provided at both ends of the valve body, and a reserved hole is penetrated through one end of the connecting flange near the edge, and an external screw is passed through the reserved hole to facilitate flange connection between the connecting flange and the external pipeline.

[0010] Furthermore, a rotating shaft is provided at the bottom of the valve body through a rotating groove, the top of the rotating shaft is welded to the bottom of the spherical valve core, the top of the spherical valve core is connected to a rotating rod, and the outer side of the top end of the rotating rod is connected to a rotating handle. A person can apply external force to the rotating handle to conveniently drive the rotating rod to rotate, thereby allowing the spherical valve core to rotate.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The utility model discloses a ball valve capable of draining sewage. When the servo electric cylinder is working, the servo electric cylinder drives the plugging plate to be pressed into the plugging groove. By rotating the rotating handle, the rotating rod and the spherical valve core are conveniently driven to rotate, so that the spherical valve core is in a closed state. At this time, a relatively closed structure is formed between the inner wall of the valve body and the plugging plate and the spherical valve core. When the solenoid valve is opened and the external water supply mechanism injects high-pressure water into the closed structure, the accumulated sewage and impurities in the valve body can be discharged through the sewage pipe.

[0019] Wherein, a rotary sealing plug 9 is arranged in the thread groove through an internal thread.

[0020] In this embodiment, Figure 1-3 As shown, the rotary sealing plug 9 is conveniently installed in the thread groove through the internal thread.

[0021] Wherein, connecting flanges 2 are provided at both ends of the valve body 1, and a reserved hole 3 is penetrated and opened near the edge of one end of the connecting flange 2.
