Description

Technical Field

[0001] The utility model belongs to the field of ball valves and relates to a ball valve, in particular to a novel filtering ball valve. Background Art

[0002] The opening and closing parts of the ball valve are driven by the valve stem and rotate around the axis of the ball valve. It can also be used for fluid regulation and control. The multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction of the medium in the pipeline, but also close any channel and connect the other two channels. Ball valves are divided into pneumatic ball valves, electric ball valves, and manual ball valves according to the driving method.

[0003] Traditional ball valves are mainly used to control the flow of fluids, while the filtering function is usually achieved by a special filter. However, in some applications, setting the filter and ball valve separately not only increases the complexity of the pipeline system, but may also cause the fluid to be contaminated again by impurities inside the pipeline after passing through the filter. Summary of the invention

[0004] The utility model aims to provide a novel combined filtering ball valve in view of the above problems existing in the prior art.

[0005] The objectives of the utility model can be achieved through the following technical solutions: a new type of filtering ball valve, comprising a valve body and a water inlet and a water outlet respectively located at two ends of the valve body, characterized in that a ball valve for cutting off the flow of liquid is arranged inside the valve body, and a valve stem for controlling the switch of the ball valve is arranged at the upper end of the ball valve, a valve seat for fixing the ball valve is arranged between the valve body and the ball valve, the valve seat is located at the water inlet, a filtering device for filtering liquid impurities is arranged, and an installation groove for facilitating the installation of the filtering device is opened on the valve seat, a protrusion for convenient clamping is arranged in the installation groove, a buckle corresponding to the installation groove is arranged on the filtering device, and a clamping block matching the protrusion is arranged on the buckle, a filter cover is arranged on the filter cover, a compression spring connected to the buckle is arranged on the filter cover, and pressing plates for pressing the compression spring are arranged at both ends of the filter cover.

[0006] In the above-mentioned novel filtering ball valve, a filter screen for filtering impurities is arranged on the filter cover, and the filter screens are connected by a supporting frame, and a base for stabilizing the filtering device is arranged at the bottom of the filter cover.

[0007] In the above-mentioned novel filter ball valve, the filter device is designed as a detachable structure, which is convenient for users to replace the filter medium according to needs.

[0008] Compared with the prior art, this new filter ball valve integrates filtering and control functions, simplifies the piping system, and reduces installation and maintenance costs; has good filtering effect, effectively removes impurities in the fluid, and improves fluid cleanliness; the filter component is detachable, which is convenient for replacement and maintenance; it is suitable for various fluid media, especially for occasions with high requirements for fluid cleanliness.

DETAILED DESCRIPTION

[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0013] like Figure 1 , Figure 2 As shown, the novel filtering ball valve comprises a valve body 1 and a water inlet 2 and a water outlet 3 respectively located at both ends of the valve body 1. A ball valve 4 for cutting off the flow of liquid is arranged inside the valve body 1, and a valve stem 5 for controlling the switch of the ball valve 4 is arranged at the upper end of the ball valve 4. A valve seat 6 for fixing the ball valve 4 is arranged between the valve body 1 and the ball valve 4. The valve seat 6 is located at the water inlet 2 and a filtering device 7 for filtering liquid impurities is arranged. The fluid first enters the filtering device 7 from the water inlet 2, and is filtered by the filtering device 7 to remove impurities therein, and then flows to the ball valve 4. A mounting groove 8 for facilitating the installation of the filtering device 7 is opened on the valve seat 6, and a protrusion 9 for convenient clamping is arranged in the mounting groove 8. The filtering device 7 is provided with a filter 7 for filtering liquid impurities. The device 7 is provided with a buckle 10 corresponding to the mounting groove 8, and the buckle 10 has a block 11 that fits with the protrusion 9. The filter device 7 is provided with a filter cover 12, and the filter cover 12 is provided with a compression spring 13 connected to the buckle 10. Pressing plates 14 for pressing the compression spring 13 are provided at both ends of the filter cover 12. Under normal working conditions, the compression spring 13 will enter a loose state, and the block 11 will be engaged with the protrusion 9 to fix the filter device 7 on the valve seat 6; by pressing the pressing plate 14 to compress the compression spring 13 as a whole, the buckle 10 is pulled out from the mounting groove 8, so that the filter device 7 can be taken out from the valve body 1, which is convenient for clearing impurities on the filter device 7.

[0014] In further detail, a filter screen 15 for filtering impurities is disposed on the filter cover 12, and the filter screens 15 are connected to each other via a support frame 16. A base 17 for stabilizing the filter device 7 is disposed at the bottom of the filter cover 12.

[0015] To further elaborate, the filter device 7 is designed to be a detachable structure, so that the user can replace the filter medium as needed.

[0016] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0017] Although this article uses more terms such as valve body 1, water inlet 2, water outlet 3, ball valve 4, valve stem 5, valve seat 6, filter device 7, installation groove 8, protrusion 9, buckle 10, block 11, filter cover 12, compression spring 13, pressing plate 14, filter screen 15, support frame 16, base 17, etc., it does not exclude the possibility of using other terms.
