Therefore, the directional words used are used to illustrate rather than limit the invention.

[0029] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0030] Embodiment: A static hydraulic balancing valve pressure regulating device, see attached Figure 1 -Attached Figure 4 , including a valve pipe 1, an inlet pipe 2, an outlet pipe 3, a regulating valve 4, a plate 8, a filter pipe 5, a limit pipe 6 and a collecting pipe 7, wherein the valve pipe 1 is vertically arranged, the top of the valve pipe 1 is sealed, and the bottom is open; the inlet pipe 2 is fixedly connected to one side of the valve pipe 1; the outlet pipe 3 is fixedly connected to the other side of the valve pipe 1, and the height of the connection between the outlet pipe 3 and the valve pipe 1 is higher than the inlet pipe 2; the regulating valve 4 is used to adjust the pressure of water entering the outlet pipe 3; the plate 8 is fixedly connected to the valve pipe 1 and is located between the inlet pipe 2 and the outlet pipe 3, and a through hole 81 vertically penetrating the plate 8 is provided on the plate 8; the filter pipe 5 is fixedly connected to the bottom of the plate 8, and the top of the filter pipe 5 is open and aligned with the through hole 81; the limit pipe 6 is fixedly connected to the bottom of the valve pipe 1, and the diameter of the limit pipe 6 gradually decreases from top to bottom; the collecting pipe 7 is detachably connected to the bottom of the valve pipe 1 and the bottom is sealed, and the limit pipe 6 is located in the collecting pipe 7.

[0031] Before the water enters the regulating valve 4, it is first filtered through the filter tube 5, so that impurities are not easily accumulated at the regulating valve 4, thereby preventing the regulating valve 4 from being easily blocked; some of the impurities filtered out at the filter tube 5 will pass downward through the limiting tube 6 into the collecting tube 7, and due to the special structure of the limiting tube 6 with a larger diameter at the top and a smaller diameter at the bottom, the impurities entering the limiting tube 6 are not easy to leave the collecting tube 7 in the reverse direction, thereby allowing some impurities to be collected in the collecting tube 7.

[0032] The regulating valve 4 includes a valve seat 41 and a valve core 42. The valve seat 41 is arranged in an annular shape and is fixedly connected to the inner wall of the valve pipe 1. The valve seat 41 is arranged at the bottom of the connection between the water outlet pipe 3 and the valve pipe 1. The top of the valve seat 41 is arranged as an arc surface extending downward and toward the inside of the valve seat 41; the valve core 42 slides up and down in the valve pipe 1 and the outer side of the bottom of the valve core 42 can cooperate with the arc surface of the top of the valve seat 41, and the outer side of the valve core 42 is connected to the inner wall of the valve pipe 1.

[0033] The distance between the valve core 42 and the valve seat 41 is adjusted by moving the valve core 42 up and down, thereby adjusting the water pressure.

[0034] Specifically, the regulating valve 4 also includes a rotating rod 43 and a hand wheel 44 . The rotating rod 43 is coaxially arranged with the valve tube 1 and threadedly connected to the top of the valve tube 1 . The rotating rod 43 is fixedly connected to the top of the valve core 42 . The hand wheel 44 is fixedly connected to the top of the rotating rod 43 .

[0035] Specifically, a spiral plate 51 is fixedly connected to the outside of the filter tube 5, and the spiral plate 51 spirals downward around the axis of the filter tube 5. The water sent into the valve tube 1 by the water inlet pipe 2 directly impacts the position outside the filter tube 5 near the top of the filter tube 5; through the setting of the spiral plate 51 spirally downward, the water sent to the outside of the filter tube 5 by the water inlet pipe 2 will spirally flow downward under the guidance of the spiral plate 51, and in the process of water flow, the impurities on the surface of the filter tube 5 can be impacted and driven to flow downward, so that the impurities can pass through the limiting pipe 6 downward under the action of the water flow and enter the collection pipe 7.

[0036] Specifically, a lifting rod 61 coaxial with the limiting tube 6 is provided at the bottom of the limiting tube 6. The lifting rod 61 vertically passes through the bottom of the limiting tube 6. One end of the lifting rod 61 extending into the limiting tube 6 is fixedly connected with a sealing plug 62. When the sealing plug 62 is pressed against the inner cavity of the limiting tube 6 near the bottom, the bottom of the limiting tube 6 is sealed. An elastic member 63 is provided at the bottom of the limiting tube 6. The elastic member 63 is used to push the lifting rod 61 downward to drive the sealing plug 62 to be pressed against the inner cavity of the limiting tube 6 near the bottom. A push rod 71 is fixedly connected inside the collecting tube 7. When the collecting tube 7 is threadedly connected to the bottom of the valve tube 1, the push rod 71 pushes the lifting rod 61 upward to separate the sealing plug 62 from the limiting tube 6.

[0037] By setting the lifting rod 61 and the elastic member 63, when the collecting tube 7 is installed at the bottom of the valve tube 1, under the action of the top rod 71, the sealing plug 62 is separated from the bottom of the limiting tube 6 upward, so that the water flow and impurities in the water flow can smoothly pass through the limiting tube 6 into the collecting tube 7; when the collecting tube 7 is disassembled, the restraint of the top rod 71 is lost, and under the action of the elastic member 63, the lifting rod 61 moves downward, thereby driving the sealing plug 62 to fit downward with the bottom of the limiting tube 6, thereby sealing the bottom of the limiting tube 6, so that water cannot pass through the limiting tube 6 downward.

[0038] Specifically, the bottom of the lifting rod 61 is fixedly connected to the limit plate 64, the elastic member 63 is configured as a spring, the spring is sleeved outside the lifting rod 61, and the two ends of the spring are respectively fixedly connected to the bottom of the limit tube 6 and the top of the limit plate 64.

[0039] 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.
