Description

Technical Field

[0001] The utility model belongs to the technical field of valves, and particularly relates to a ball valve with a filtering function and being detachable. Background Art

[0002] A ball valve is a valve in which the closing and opening member (ball) is driven by a valve stem and rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids. Among them, in a hard-sealed V-type ball valve, there is a strong shearing force between the V-type ball core and the metal valve seat surfacing with hard alloy, which is particularly suitable for media containing fibers, tiny solid particles, etc. A multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the media on the pipeline, but also close any channel to connect the other two channels.

[0003] At present, some valves are provided with a filter net inside, but impurities accumulate on the filter net and are not easy to fall off and difficult to discharge, which easily causes blockage inside the valve and makes the ball valve unable to be used. Summary of the Invention

[0004] The purpose of the utility model is to provide a ball valve with a filtering function and being detachable for the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved by the following technical solutions: A ball valve with a filtering function and being detachable includes a valve body. A valve ball is arranged inside the valve body. The valve ball is connected with a valve stem at the upper end. It is characterized in that an inlet part is arranged at the water inlet of the valve body, and an outlet part is arranged at the water outlet of the valve body. An inlet for liquid to flow in is opened on the outlet part. The inlet part and the outlet part are respectively abutted against the valve ball and controlled by the valve ball for the liquid to flow through. A flow pipeline for liquid to flow through is arranged inside the valve ball, and the flow pipeline is arranged in an L-shaped structure. An installation part is arranged inside the valve body. The installation part is detachably fixed and installed at the bottom end of the valve body through fixing bolts. An arc groove for the valve ball to rotate and connected with the arc surface of the valve ball is opened at the upper end of the installation part. An inlet for liquid to flow in is opened at the upper end of the installation part. Outlets for liquid to flow out are opened on both sides of the installation part. Filtering parts for filtering are fixedly arranged on the installation part relative to the two outlets.

[0006] In the above-mentioned ball valve with a filtering function and being detachable, the filtering part is arranged in a concave structure, and the filtering part is fixedly installed on the installation part through fixing bolts.

[0007] In the above-mentioned ball valve with a filtering function and being detachable, a valve cover is arranged at the upper end of the valve body. A sealing part for enhancing the seal is arranged on the valve stem. A plurality of sealing rings for sealing are arranged between the outlet part and the valve body.

[0008] Compared with the prior art, the ball valve with a filtering function and being detachable has an installation member provided on the valve body, and a filtering member is provided on the installation member, enabling the staff to only disassemble the installation member when removing debris on the filtering member, which is convenient for maintenance and cleaning.

[0012] The following are specific embodiments of the present utility model in combination with the drawings to further describe the technical solutions of the present utility model, but the present utility model is not limited to these embodiments.

[0013] As Figure 1 , Figure 2 shown, the ball valve with a filtering function and being detachable includes a valve body 1. A valve ball 2 is arranged inside the valve body 1. A valve stem is connected to the upper end of the valve ball 2. A water inlet member 3 is arranged at the water inlet 5 of the valve body 1. A water outlet member 4 is arranged at the water outlet 6 of the valve body 1. A water inlet 5 for liquid to flow in is formed on the water outlet member 4. The water inlet member 3 and the water outlet member 4 respectively abut against the valve ball 2 and are controlled by the valve ball 2 for liquid flow. A flow-through pipe 7 for liquid to flow through is provided inside the valve ball 2, and the flow-through pipe 7 is arranged in an L-shaped structure. An installation member 8 is arranged inside the valve body 1. The installation member 8 is detachably fixed to the bottom end of the valve body 1 by fixing bolts. When the ball valve main body is used for a long time, a large amount of impurities adhere to the filtering member 9 and the filtering effect is poor. The installation member 8 can be disassembled to replace or clean the filtering member 9 on the installation member 8, avoiding replacing the entire valve body 1 and saving the use cost. An arc groove for the valve ball 2 to rotate and abut against the arc surface of the valve ball 2 is formed at the upper end of the installation member 8. A water inlet 5 for liquid to flow in is formed at the upper end of the installation member 8. Water outlets 6 for liquid to flow out are formed on both sides of the installation member 8. Filtering members 9 for filtering are fixedly arranged on the installation member 8 and opposite to the two water outlets 6.

[0014] Specifically, when the valve ball 2 is opened, the liquid passes through the water inlet part 3 of the valve body 1, flows into the mounting part 8 through the flow pipe 7 of the valve ball 2, is filtered by the filter part 9 on the mounting part 8, flows into the redundant space of the valve body 1, and then enters the water outlet part 4 through the water inlet 5 of the water outlet part 4 for water outlet.

[0015] Specifically, the filter part 9 is arranged in a concave structure, and the filter part 9 is fixedly installed on the mounting part 8 through fixing bolts.

[0016] Specifically, a valve cover is arranged at the upper end of the valve body 1, a sealing part 11 for enhancing the seal is arranged on the valve rod, and a plurality of sealing rings 10 for sealing are arranged between the water outlet part 4 and the valve body 1.

[0017] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0018] Although terms such as the valve body 1, valve ball 2, water inlet part 3, water outlet part 4, water inlet 5, water outlet 6, flow pipe 7, mounting part 8, filter part 9, sealing ring 10, sealing part 11, etc. in the drawings are used more frequently in this article, the possibility of using other terms is not excluded. Using these terms is only for more conveniently describing and explaining the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.
