Description

Technical Field

[0001] The utility model relates to the technical field of pipeline sewage discharge, in particular to an online slag discharge ball valve. Background Art

[0002] The service life of valves on newly built pipelines is relatively short during operation. The reason is that there are all kinds of waste residues inside the newly built pipelines, such as welding rods, welding slag, welding rod heads and other debris, etc. These debris are small in size, heavy in weight, and high in hardness. During the transportation process with the medium, they will cause great damage to the equipment under jurisdiction (such as valves or other equipment), threatening the normal and safe operation of the pipeline.

[0003] The ball valve is one of the commonly used valves in the above pipelines. Its opening and closing parts are spheres and driven by the valve stem. It rotates around the axis of the ball valve, which can not only control the flow of fluid but also adjust the flow rate. It is convenient to use. When the existing ball valve is used in the newly built pipeline, the waste residue can easily move to the valve with the fluid, which can easily damage the sealing surface of the ball valve and reduce the service life of the ball valve. Utility Model Content

[0004] The utility model aims to provide an online slag discharge ball valve to solve the technical problem in the prior art that the valve is easily damaged by waste slag when used on a newly built pipeline, resulting in a reduced service life.

[0005] To achieve the above-mentioned purpose, an online slag discharge ball valve of the utility model adopts the following technical scheme: an online slag discharge ball valve, comprising a ball valve and an inlet pipe and an outlet pipe connected to both ends of the ball valve, a first slag blocking plate is arranged at the bottom of the inner pipe wall of the inlet pipe, a second slag blocking plate is arranged at the bottom of the inner pipe wall of the outlet pipe, a first sewage discharge channel is arranged on both sides of the first slag blocking plate along the direction of medium flow on the inlet pipe, and a second sewage discharge channel is arranged on both sides of the second slag blocking plate along the direction of medium flow on the outlet pipe.

[0006] A first slag discharge port is arranged at the bottom of the inner pipe wall of the inlet pipe, a first slag discharge pipe is arranged at the first slag discharge port, a first slag blocking plate crosses the first slag discharge port in the radial direction of the inlet pipe, so that the first slag discharge port is divided into a first front slag discharge port and a first rear slag discharge port by the first slag blocking plate along the medium flow direction, and the first front slag discharge port and the first rear slag discharge port respectively form corresponding first sewage discharge channels with the first slag discharge pipe below.

[0007] A first slag discharge port is provided at the bottom of the inner pipe wall of the inlet pipe along the medium flow direction on both sides of the first slag blocking plate, and a first slag discharge pipe is correspondingly provided at each first slag discharge port, and each first slag discharge port and the corresponding first slag discharge pipe form the first sewage discharge channel.

[0008] A main slag discharge pipe is arranged below the two first slag discharge pipes, and the main slag discharge pipe and the two first slag discharge pipes form a "Y"-shaped pipe.

[0009] A second slag discharge port is arranged at the bottom of the inner pipe wall of the outlet pipe, and a second slag discharge pipe is arranged at the second slag discharge port. The second slag blocking plate crosses the second slag discharge port in the radial direction of the outlet pipe, so that the second slag discharge port is divided into a second front slag discharge port and a second rear slag discharge port by the second slag blocking plate along the medium flow direction. The second front slag discharge port and the second rear slag discharge port respectively form corresponding second sewage discharge channels with the second slag discharge pipe below.

[0010] A second slag discharge port is provided at the bottom of the inner pipe wall of the outlet pipe along the medium flow direction on both sides of the second slag blocking plate, and a second slag discharge pipe is correspondingly provided at each second slag discharge port, and each second slag discharge port and the corresponding second slag discharge pipe form the second sewage discharge channel.

[0011] A main slag discharge pipe is arranged below the two second slag discharge pipes, and the main slag discharge pipe and the two second slag discharge pipes form a "Y"-shaped pipe.

[0012] The beneficial effects of the utility model are as follows: due to the heavy weight of the debris, under the action of gravity, most of the debris will be at the bottom of the pipeline, under the action of the medium, the debris will move along the pipeline with the medium, and under the action of the first slag blocking plate of the inlet pipeline, most of the debris will be intercepted and fall into the first slag discharge channel. There will also be a small part that will follow the medium to cross the first blocking plate and enter the outlet pipeline, and will be intercepted and fall into the second slag discharge channel under the action of the second slag blocking plate, so as to prevent the medium from backflowing and rushing this part of the debris back to the ball valve. At the same time, after the ball valve is closed, the medium will flow back, and the debris in the backflow in the inlet pipeline will also be intercepted by the first blocking plate and fall into the first slag discharge channel, and the debris brought from the outlet pipeline in the backflow of the medium in the outlet pipeline will be intercepted by the second slag blocking plate and fall into the second slag discharge channel. Then, the debris can be discharged by opening the corresponding sewage discharge channel irregularly or regularly. Such a ball valve can intercept and discharge most of the debris in the newly built pipeline, which can greatly extend the service life of the ball valve. BRIEF DESCRIPTION OF THE DRAWINGS
