[0002] The flow regulating valve, also known as the self-acting flow control valve, is an intuitive and simple flow regulation and control device. By using a flow regulating valve in a pipe network, the flow can be directly set according to the design. Under the action of water, the valve can automatically eliminate the remaining head of the pipeline and the flow deviation caused by pressure fluctuations, and keep the set flow unchanged regardless of how the system pressure changes.

This makes the entire system appear to have a single function when dealing with complex environmental problems. If there is an odor in the chemical raw materials, wastewater or waste gas being transported where the flow regulating valve is located, and the valve cannot adsorb these odors, then these odors may persist and spread, leading to the deterioration of environmental quality. Summary of the Utility Model

[0019] As Figure 1 and Figure 2 shown, the present utility model provides a technical solution: a flow regulating valve, which includes a valve body 1. A valve rod 3 is fixedly installed on the side wall of the valve body 1, and a handwheel 6 is fixedly installed at the top of the valve rod 3. The valve body 1 is a prior art structure, so it will not be described in detail here. Water inlet pipes 4 and outlet pipes 2 are respectively fixedly installed at both ends of the valve body 1. A filtering mechanism for screening liquid impurities entering the regulating valve is arranged inside the water inlet pipe 4, and an auxiliary cleaning mechanism is arranged in the filtering mechanism. In the specific use process, through the design of the filtering mechanism, when water flows through the water inlet pipe 4, peculiar smell, residual chlorine, organic matters, etc. in the water are removed, thereby improving the safety of water quality.

[0020] As an implementation manner in this embodiment, as Figure 3 Figure 4 and Figure 5 shown, the filtering mechanism includes a fixing plate 5 fixed on the inner wall of the water inlet pipe 4. A second limiting groove 571 is opened at the center of the fixing plate 5. A second lower screw rod 591 is threadedly connected in the second limiting groove 571. The top of the second lower screw rod 591 is fixedly connected with a first fixing rod 52. The top of the first fixing rod 52 is fixedly connected with an upper screw rod 59. A sieve plate 51 is inserted at the top of the first fixing rod 52. A turning handle 521 is arranged on the outer wall of the upper screw rod 59. A third limiting groove 572 is opened at the bottom of the turning handle 521. The turning handle 521 is threadedly connected with the upper screw rod 59. A plurality of through holes 58 for water passage are opened at the end of the fixing plate 5. A plurality of rubber pads 56 are fixedly installed on the upper end surface of the fixing plate 5. The tops of the plurality of rubber pads 56 are in contact with the bottom of the filter element 53 and the second fixing rod 54. In the specific use process, first, align the second lower screw rod 591 at the bottom of the first fixing rod 52 with the second limiting groove 571 and rotate it downward. When the bottom of the first fixing rod 52 abuts against the fixing plate 5, stop rotating the first fixing rod 52. Place the sieve plate 51 on the top of the first fixing rod 52. At this time, align the third limiting groove 572 opened at the bottom of the turning handle 521 with the upper screw rod 59 and rotate it to fix the sieve plate 51. The sieve plate 51 blocks impurities in the water flow, so that the peculiar smell in the water is adsorbed.

A filter element 53 is fixedly sleeved on the outer wall of the second fixing rod 54. The model of the filter element 53 is X400S. The filter element 53 is filled with activated carbon particles. The strong adsorption of activated carbon is used to remove peculiar smell, residual chlorine, organic matters, etc. in the water. In the specific use process, first, align the lower screw rods at the bottom of the plurality of second fixing rods 54 with the first limiting grooves 57, and rotate the second fixing rods 54 in sequence, so that the first lower screw rod 55 is tightly threadedly connected with the first limiting grooves 57. Through the design that the filter element 53 is fixedly sleeved on the outer wall of the second fixing rod 54, smaller impurities in the water body can be absorbed, and the efficiency of adsorbing peculiar smell in the water is improved, thereby improving the safety of the water quality.

[0022] Working principle: First, align the second lower screw rod 591 at the bottom of the first fixing rod 52 with the second limiting groove 571 and rotate it downward. When the bottom of the first fixing rod 52 abuts against the fixed plate 5, stop rotating the first fixing rod 52. Place the sieve plate 51 on the top of the first fixing rod 52. At this time, align the third limiting groove 572 opened at the bottom of the rotary handle 521 with the upper screw rod 59 and rotate it to fix the sieve plate 51. The sieve plate 51 blocks impurities in the water flow. Align the lower screw rods at the bottom of the plurality of second fixing rods 54 with the first limiting grooves 57, and rotate the second fixing rods 54 in sequence, so that the first lower screw rod 55 is tightly threadedly connected with the first limiting grooves 57.
