Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage technology, specifically a water supply and drainage control device. Background Technology

[0002] Water supply and drainage is a comprehensive system engineering project aimed at providing safe, reliable, and economical water for human life and production, and effectively treating and discharging wastewater to protect the environment. Water supply and drainage systems require valves to open and close pipelines and regulate flow. However, existing valves may experience pipe vibrations due to water flow impacts during use, causing slight valve rotation and altering the flow rate. Furthermore, discharged wastewater often contains a large amount of impurities, which can easily accumulate inside valves, leading to blockages. When these impurities accumulate to a certain level, they hinder the normal opening and closing of the valves, affecting the normal operation of the water supply and drainage system. Utility Model Content

[0003] The purpose of this utility model is to provide a water supply and drainage control device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows.

[0005] A water supply and drainage control device includes an inlet pipe, an outlet pipe, and a ball valve. The ball valve is positioned between the inlet and outlet pipes. Multiple insertion holes are coaxially arrayed around the upper surface of the ball valve stem. A positioning block is fitted onto the outer surface of the valve stem, and a groove is formed along its height on the outer surface of the valve stem. A slider is provided on the inner side of the positioning block and is positioned within the groove. Multiple insertion rods are coaxially arrayed on the lower surface of the positioning block, and the insertion rods are adapted to the insertion holes. A rectangular plate is installed on the inlet pipe, and the rectangular plate is inclined. A filter screen is installed inside the rectangular plate.

[0006] Therefore, the ball valve allows for the adjustment of pipeline opening and closing as well as flow rate. The insertion hole and rod allow for locking the valve stem angle, preventing pipeline vibration caused by water flow impact, which could lead to slight valve stem rotation and changes in flow rate. Furthermore, the filter screen filters impurities in wastewater, preventing impurities from accumulating inside the valve and causing blockage, thus ensuring the normal operation of the water supply and drainage system.

[0007] Furthermore, a spring is fitted on the outer surface of the valve stem, with the two ends of the spring abutting against the positioning block and the first handwheel, respectively, and a second handwheel is installed on the outer surface of the positioning block.

[0008] Furthermore, an electric push rod is installed on the upper surface of the rectangular plate. The end of the electric push rod extends into the rectangular plate and is fitted with a mounting block. The side of the mounting block facing the filter screen is provided with bristles.

[0009] Furthermore, a drain pipe is installed at the bottom of the rectangular plate, and a drain valve is installed inside the drain pipe.

[0010] Furthermore, a flow sensor is installed inside the water outlet pipe.

[0011] Furthermore, both ends of the ball valve are connected to the inlet pipe and the outlet pipe via flanges, and a sealing gasket is installed between the two flanges.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0013] 1. This utility model, through the setting of a ball valve, can adjust the opening and closing of the pipeline and the flow rate. Through the setting of the insertion hole and the insertion rod, the angle of the valve rod can be locked, thereby avoiding the situation where the pipeline shakes due to the impact of water flow, and the valve rod rotates slightly, thus changing the flow rate.

[0014] 2. By activating the electric push rod, the telescopic end of the push rod drives the mounting block to slide up and down, which allows the bristles to clean the impurities attached to the surface of the filter screen, thus preventing the filter screen from clogging and affecting the normal flow of sewage. Furthermore, since the filter screen is set at an angle, the impurities deposited on the filter screen can slide down the inclined surface and be collected below under the action of water flow and gravity.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0022] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0023] like Figure 1-4 As shown, a water supply and drainage control device includes an inlet pipe 100, an outlet pipe 101, and a ball valve 102. The ball valve 102 is disposed between the inlet pipe 100 and the outlet pipe 101. Multiple insertion holes 103 are coaxially arrayed around a valve stem 1021 on the upper surface of the ball valve 102. A positioning block 104 is fitted onto the outer surface of the valve stem 1021, and a sliding groove is formed along its height on the outer surface of the valve stem 1021. A slider is provided on the inner side of the positioning block 104 and is disposed within the sliding groove. Multiple insertion rods 105 are coaxially arrayed on the lower surface of the positioning block 104, and the insertion rods 105 are adapted to the insertion holes 103. A rectangular plate 106 is installed on the inlet pipe 100, and the rectangular plate 106 is inclined. A filter screen 107 is disposed inside the rectangular plate 106.

[0024] During use, sewage enters through the inlet pipe 100 and is filtered by the filter screen 107, which intercepts impurities in the sewage, preventing them from entering the ball valve 102. When the ball valve 102 needs to be adjusted, the positioning block 104 can be slid upward to drive the insert rod 105 out of the insertion hole 103. At this time, the valve stem 1021 is released from its fixed position, so it can be rotated for adjustment. After adjustment, the positioning block 104 slides down and drives the insert rod 105 back into the insertion hole 103. Due to the setting of the sliding groove and the slider, the positioning block 104 can only slide on the valve stem 1021 and cannot rotate independently. Therefore, the valve stem 1021 can be locked to prevent it from rotating, thus avoiding the situation where the pipeline shakes due to the impact of water flow, causing the valve stem 1021 to rotate slightly and thus changing the flow rate.

[0025] Specifically, a spring 200 is fitted on the outer surface of the valve stem 1021. The two ends of the spring 200 abut against the positioning block 104 and the first handwheel 1022, respectively. A second handwheel 300 is installed on the outer surface of the positioning block 104. The spring 200 applies a continuous pushing force to the positioning block 104, so that the insertion rod 105 can be stably inserted into the insertion hole 103, avoiding the situation where the insertion rod 105 is dislodged from the insertion hole 103 due to pipeline vibration. Furthermore, with the setting of the second handwheel 300, when the valve stem 1021 is rotated, the first handwheel 1022 and the second handwheel 300 can be held at the same time and the second handwheel 300 can be pulled up. Then, the first handwheel 1022 and the second handwheel 300 can be rotated at the same time.

[0026] Specifically, an electric push rod 400 is installed on the upper surface of the rectangular plate 106. The telescopic end of the electric push rod 400 extends into the rectangular plate 106 and is fitted with an installation block 401. The side of the installation block 401 facing the filter screen 107 is provided with bristles 402. By activating the electric push rod 400, its telescopic end drives the installation block 401 to slide up and down, allowing the bristles 402 to clean the impurities attached to the surface of the filter screen 107, preventing the filter screen 107 from becoming clogged and affecting the normal flow of sewage. Furthermore, since the filter screen 107 is inclined, the impurities deposited on the filter screen 107 can slide down the inclined surface and be collected below under the action of water flow and gravity.

[0027] Specifically, a drain pipe 500 is installed at the bottom of the rectangular plate 106. A drain valve 501 is installed inside the drain pipe 500. Impurities slide down into the drain pipe 500 and are collected. When the drain valve 501 is opened, the sewage containing impurities can be discharged, which plays a cleaning role.

[0028] Specifically, the outlet pipe 101 is equipped with a flow sensor 600. The flow sensor 600 can monitor the water flow speed and flow rate, helping to determine whether the pipe is operating normally and to understand changes in drainage demand.

[0029] Specifically, both ends of the ball valve 102 are connected to the inlet pipe 100 and the outlet pipe 101 via flanges, and a sealing gasket is provided between the two flanges. The flanges and sealing gaskets can stably connect the inlet pipe 100, the outlet pipe 101 and the ball valve 102 together.

[0030] The above is a detailed description of the present invention in conjunction with specific embodiments, and it should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, any equivalent substitutions or obvious modifications made without departing from the concept of the present invention, and which have the same performance or use, should be considered as falling within the patent protection scope defined by the submitted claims.
