[0002] A screw thread ball valve is a valve whose closing part is a sphere, and the sphere rotates around the center line of the valve body to achieve opening and closing. The internal thread ball valve is mainly used on various pipelines. Its working temperature ranges from -29°C to 180°C. The internal thread ball valve has a relatively simple structure, a relatively small volume, a relatively light weight, and is very convenient to operate and recycle, and has a relatively wide application range.

[0003] After retrieval, as disclosed in the Chinese patent document CN205978554U, a straight pipe type internal thread ball valve reduces the operating friction caused by the rotation of the valve stem by setting a segmented elastic steel-plastic pressing ring, and the outer steel sleeve of the pressing ring set can prevent the valve stem from swinging during operation. Then, through the friction provided by the inner elastic rubber, the opening and closing of the valve are lighter and more flexible. However, there are still the following defects:

[0004] When the above-mentioned straight pipe type internal thread ball valve is in use, it cannot filter impurities in water, and is prone to blockage at the valve core after long-term use, resulting in unsmooth opening and closing of the equipment, and it is not convenient to clean the inside of the equipment. Content of the Utility Model

[0005] The purpose of the utility model is to provide a straight pipe type internal thread ball valve to solve the problems of the straight pipe type internal thread ball valve mentioned in the above background technique, that is, it cannot filter impurities in water, is prone to blockage at the valve core after long-term use, resulting in unsmooth opening and closing of the equipment, and it is not convenient to clean the inside of the equipment.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A straight pipe type internal thread ball valve includes a ball valve body.

Specific implementation mode

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] Please refer to Figures 1-6 , the present invention provides a straight-through type internal thread ball valve, including a ball valve body 1, a valve core 101, a knob 102, a water inlet pipe 2, a magnetic ring 201, an impurity removal net 3, a first positioning ring 301, a second positioning ring 302, a sealing ring 303, a positioning plate 304, a collection hopper 305, a connecting pipe 306, an impurity discharge pipe 4, a sealing plug 401, a connecting column 402, a cleaning plate 403, and a water outlet pipe 5. A valve core 101 is arranged inside the ball valve body 1, the top of the valve core 101 is connected with a knob 102, a water inlet pipe 2 is arranged on the side of the ball valve body 1, a water outlet pipe 5 is connected to the side of the ball valve body 1 away from the water inlet pipe 2, an impurity removal net 3 is arranged inside the water inlet pipe 2, the impurity removal net 3 is of a conical structure, a first positioning ring 301 of a tubular structure is fixed at one end of the impurity removal net 3 away from the ball valve body 1, a second positioning ring 302 of a circular ring structure is fixed at one end of the first positioning ring 301 away from the impurity removal net 3. The arranged first positioning ring 301 can make the impurity removal net 3 be fixedly hung inside the water inlet pipe 2, and then the position of the impurity removal net 3 is restricted by the second positioning ring 302. When the device is connected to an external water pipe, the second positioning ring 302 can be clamped between the water inlet pipes 2 through the connection of the external water pipe to complete the fixation of the impurity removal net 3. Four groups of positioning plates 304 are vertically arranged on the surface of the impurity removal net 3, and one end of the positioning plate 304 away from the impurity removal net 3 is in contact with the inner side of the water inlet pipe 2, and the water inlet pipe 2 is slidably connected with the positioning plate 304. The arranged four groups of positioning plates 304 can stabilize the position of the impurity removal net 3 inside the water inlet pipe 2, so that the impurity removal net 3 can be centered and fixed inside the water inlet pipe 2.

[0025] One end of the impurity removal net 3 away from the first positioning ring 301 is fixed with a collecting hopper 305 in a funnel shape. One end of the collecting hopper 305 away from the impurity removal net 3 is fixed with a connecting pipe 306. The connecting pipe 306 is inserted and connected with the impurity discharge pipe 4. The provided collecting hopper 305 can, when the device is in use, use the water flow to wash the impurities on the impurity removal net 3 into the interior of the collecting hopper 305, and then the impurities can be collected through the collecting hopper 305 and pushed into the interior of the impurity discharge pipe 4 for temporary storage, avoiding the situation that the flow rate of the water inlet pipe 2 decreases due to the accumulation of impurities. At the connection between the second positioning ring 302 and the water inlet pipe 2, there is a sealing ring 303, and at the connection between the sealing ring 303 and the water inlet pipe 2, there is a magnetic attraction ring 201. The sealing ring 303 can increase the sealing performance of the connection of the second positioning ring 302, and the magnetic attraction ring 201 can adsorb the second positioning ring 302, facilitating the quick installation of the impurity removal net 3 and preventing the impurity removal net 3 from falling off.

[0026] The maximum diameter dimension of the second positioning ring 302 is larger than the maximum diameter dimension of the first positioning ring 301. The maximum diameter dimension of the first positioning ring 301 is consistent with the diameter dimension of the inner wall of the water inlet pipe 2, and the water inlet pipe 2 and the first positioning ring 301 are slidably connected. The second positioning ring 302 arranged in this way can prevent the impurity removal net 3 from falling into the interior of the impurity removal net 3 and play a role in restricting the position of the impurity removal net 3. One end of the impurity removal net 3 is connected with an impurity discharge pipe 4. The impurity discharge pipe 4 is in an "L" shape, and one end of the impurity discharge pipe 4 away from the impurity removal net 3 is arranged outside the water inlet pipe 2. A sealing plug 401 is threadedly connected to one end of the impurity discharge pipe 4 away from the impurity removal net 3. Through the provided impurity discharge pipe 4, the filtered impurities can be discharged, facilitating the cleaning of the impurity removal net 3 inside the device. In the middle of the top of the sealing plug 401 close to the impurity discharge pipe 4, there is a connecting column 402. On the side of the connecting column 402, there are four groups of cleaning plates 403, and the cleaning plates 403 are inclined on the connecting column 402 and are slidably connected inside the impurity discharge pipe 4. In this way, after the sealing plug 401 is disassembled, the internal cleaning plates 403 can rotate inside the impurity discharge pipe 4 to discharge the accumulated impurities inside.

[0027] When the embodiment of the present application is in use: By arranging an impurity removal net 3 with a conical structure inside the water inlet pipe 2, when the water flow inside the water inlet pipe 2 passes through, the impurities in the water will be filtered by the impurity removal net 3 and remain on the impurity removal net 3. Under the scouring of the water flow, the impurities on the impurity removal net 3 will gradually be washed into the interior of the collection hopper 305 for collection, and then gradually move into the interior of the impurity discharge pipe 4. When inside the impurity discharge pipe 4, the impurities will be under water pressure and gradually accumulate inside the impurity discharge pipe 4. When cleaning is required, the sealing plug 401 of the impurity discharge pipe 4 can be rotated to remove the sealing plug 401. During this process, the sealing plug 401 will drive the cleaning plate 403 to rotate through the connecting column 402, loosening the interior of the impurity discharge pipe 4. In this way, the impurities inside the opened impurity discharge pipe 4 will be washed out by the water flow to complete the internal cleaning. When the impurity removal net 3 needs to be replaced, only the water pipe connected to the water inlet pipe 2 needs to be untied, and one end of the second positioning ring 302 will lose its restriction, so that the impurity removal net 3 can be disassembled and a new impurity removal net 3 can be replaced. In this way, the use of such a straight-through type internal thread ball valve is completed. It should be noted that the present utility model is a straight-through type internal thread ball valve, and the components are all common standard parts or parts known to those skilled in the art. Its structure and principle can be known to those skilled in the art through technical manuals or through conventional experimental methods.
