Description

Technical Field

[0001] The utility model relates to the technical field of valve bodies, and more specifically, to a valve body with a multifunctional filtering structure. Background Art

[0002] The valve body is a major component in the valve. There are different mechanical manufacturing methods according to the pressure level, such as casting, forging, etc. However, when the valve body is in use, due to the presence of impurities in the water flow, after long-term use, the impurities will accumulate at the sealing ring inside the valve body, thereby affecting the normal use of the valve body and the sealing ring, and affecting the flow-stopping effect of the valve body. At the same time, after some valve bodies are closed, the water flow will flow back. When the external temperature drops, the internal water flow is prone to freezing. The freezing of water inside the valve body will not only affect the normal delivery of the water flow, but also affect the service life of the valve body.

[0003] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0021] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] A valve body with a multifunctional filtering structure, such as Figure 1 and Figure 2 As shown, it includes a valve body shell 1, a valve plate 2 is provided on one side of the valve body shell 1, and a filter plate 1 3 and a filter plate 2 4 are provided on the other side of the valve body shell 1, and the filter plate 1 3 and the filter plate 2 4 are closely attached to each other. Specifically, the valve body shell 1, the filter plate 1 3 and the filter plate 2 4 are all made of corrosion-resistant material, and the corrosion-resistant material is stainless steel. By arranging the valve plate 2, it is convenient for the operator to open and close the valve body, so as to control the flow rate. By arranging the filter plate 1 3 and the filter plate 2 4, it is possible to grade and filter particles of different sizes in the valve body, thereby improving the filtering effect. The stainless steel material has good hardness and corrosion resistance, so that the filter plate 1 3, the filter plate 2 4 and the valve body shell 1 made of it are not easy to be corroded, and can maintain a long service life in harsh working environments, thereby reducing maintenance costs and replacement frequency.

[0023] Specifically, a slide groove 5 for accommodating the sliding of filter plate 1 3 and filter plate 2 4 is opened on the inner wall of the valve body shell 1, and a sealing gasket 10 made of rubber material is bonded to the inner wall of the slide groove 5. The rubber sealing gasket 10 can provide a good sealing effect to prevent fluid leakage inside the valve body and ensure the sealing performance of the valve body. A lifting rod 6 is provided on the filter plate 1 3 and the filter plate 2 4, and one end of the lifting rod 6 is located outside the valve body shell 1. Furthermore, filter plate 1 3 and filter plate 2 4 are provided with filter holes 9, and the aperture of the filter hole 9 on the filter plate 1 3 is larger than that of the filter hole 9 on the filter plate 2 4. The filter plate 1 3 and the filter plate 2 4 can chop the blocked impurities by sliding up and down. The lifting rod 6 is provided to facilitate the operator to slide the position of the filter plate 1 3 and the filter plate 2 4, so that the two can slide relative to each other and perform shredding operations on the blocked garbage, thereby ensuring smooth circulation inside the valve body, reducing maintenance requirements and improving the self-cleaning ability of the valve body. At the same time, filter plates 1 3 and 2 4 are provided with filter holes 9 with different apertures, allowing the valve body to perform graded filtration on particles of different sizes. Larger particles are intercepted by the filter plate 1 3, while smaller particles are intercepted by the filter plate 2 4 after passing through the filter plate 1 3. The aperture of the filter plate 1 3 is relatively large, so it can handle larger particles of impurities, reducing the burden on the filter plate 2 4, thereby improving the overall filtration efficiency.

[0024] The inner wall of the valve body shell 1 is inclined, and the inner diameter of the valve body shell 1 becomes larger as it is closer to the filter plate 3. When the operator closes the valve plate 2 on one side, water will flow back, and the inclined inner wall allows the water to flow down along the inner wall. This design can prevent water from accumulating in the valve body, while also reducing fluid resistance and improving fluid flow efficiency.

[0025] Furthermore, a groove 7 is provided at the bottom of the valve body shell 1, and a heating wire 8 is provided in the groove 7. By providing the heating wire 8, the problem of ice formation in the water flow inside the valve body can be reduced, which solves the problem that when some valve bodies are currently in use, impurities in the water flow are easy to affect the normal use of the valve plate 2 and the sealing ring in the valve body and affect the flow-stopping effect of the valve body, and the water flow inside the valve body is easy to freeze at a low temperature and affect the service life of the valve body. The design of the groove 7 provides a place for the heating wire 8 to protect it. Furthermore, a cover for covering the notch of the groove 7 is rotatably connected to the valve body shell 1. The cover plate 11 is provided with a handle 12. By providing the cover plate 11, the heating wire 8 in the groove 7 is protected, and dust and impurities from the outside are prevented from entering the groove 7, thereby extending its service life. The design of the handle 12 makes it convenient for the operator to flip the cover plate 11, thereby improving the operating efficiency. The handle 12 is provided with an anti-slip sleeve 13, and the anti-slip sleeve 13 is provided with a plurality of anti-slip grooves 14 arranged in an array. By providing the anti-slip sleeve 13 and the anti-slip grooves 14, the contact area when the operator holds the handle 12 is increased, the friction is increased, and the occurrence of slipping is avoided.

[0026] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
