Description

Technical Field

[0001] The utility model relates to the technical field of globe valves, in particular to an efficient sewage discharge globe valve. Background Technique

[0002] A globe valve, also known as a stop valve, belongs to a forced-sealing valve. Due to the small friction between the sealing surfaces during the opening and closing process, the globe valve is relatively durable, has a small opening height, is easy to manufacture and maintain, and is applicable not only to medium and low pressures but also to high pressures.

[0003] Under the prior art, for example, a Chinese patent with the publication number CN218582251U discloses a sewage discharge globe valve, which includes a globe valve body. Both ends of the globe valve body are provided with connecting pipes communicated with the inside. A sedimentation tank is provided on one of the connecting pipes. A filter box is provided in the sedimentation chamber. A through groove is opened on the left side of the filter box, a filter screen is embedded on the right side of the filter box, and the filter box is in plug-in fit with the sedimentation chamber.

[0004] Although the above device can filter the flowing water in the pipe and can be taken out for cleaning, in the actual use process, the cleaning time of the filter screen cannot be accurately determined, and the device lacks an automatic cleaning time indication or alarm system. Users need to manually judge whether the filter screen needs to be cleaned, resulting in the filter screen not being processed in time when it needs to be cleaned, thus affecting the normal operation of the valve. The lack of a monitoring mechanism for the cleaning cycle may lead to unstable maintenance frequencies. Without clear cleaning prompts, users may clean too early or too late, affecting the efficiency and service life of the valve. Therefore, we propose an efficient sewage discharge globe valve to solve the above problems. Content of the Utility Model

[0005] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by the utility model is as follows:

[0007] An efficient sewage discharge globe valve includes a water inlet pipe. One end of the water inlet pipe is provided with a control assembly. The end of the control assembly away from the water inlet pipe is provided with a drain pipe. The drain pipe is connected to the water inlet pipe through the control assembly. The control assembly includes an assembly pipe. A fixing ring is fixedly connected to one end of the inner cavity of the assembly pipe close to the drain pipe. A plurality of fixing cylinders are fixedly connected to one side of the fixing ring close to the water inlet pipe. A telescopic spring is arranged at the bottom of the inner cavity of the fixing cylinder. A moving seat is arranged inside the fixing cylinder. One side of the moving seat close to the water inlet pipe is fixedly connected to a moving roller. One end of the moving roller away from the moving seat passes through the fixing cylinder and extends into the assembly cylinder. A moving ring is fixedly connected to one end of the moving roller in the assembly cylinder. A touch rod is fixedly connected to one side of the moving ring away from the water inlet pipe. A pressure sensor is arranged at one end of the touch rod away from the moving ring. The pressure sensor is fixedly connected to the fixing ring.

[0008] Preferably, an internal thread is provided on the inner wall of one end of the assembly pipe close to the water inlet pipe, an external thread matching the internal thread is provided on one end of the water inlet pipe close to the assembly pipe, and the water inlet pipe is threadedly connected to the assembly pipe.

[0009] Preferably, one end of the assembly pipe away from the water inlet pipe is fixedly connected to the drain pipe, the water inlet pipe, the assembly pipe and the drain pipe are communicated, and a handle is fixedly connected to one end of the assembly pipe close to the drain pipe.

[0010] Preferably, the fixing ring is fixedly connected to the assembly pipe, and a plurality of fixing cylinders are evenly distributed around the axis of the fixing ring.

[0011] Preferably, the moving seat is slidably connected to the inner wall of the fixing cylinder, a connecting cylinder is fixedly connected to one side of the moving seat close to the fixing ring, and one end of the telescopic spring close to the water inlet pipe contacts the bottom of the inner cavity of the connecting cylinder.

[0012] Preferably, the outer wall of the moving ring is slidably connected to the inner wall of the assembly cylinder, a plurality of guiding seats are fixedly connected to the periphery of the moving ring, and the plurality of guiding seats are evenly distributed around the axis of the moving ring.

[0013] Preferably, a guiding groove matching the guiding seat is provided on the inner wall of the assembly cylinder, and the guiding seat is slidably connected to the wall of the guiding groove.

[0014] Preferably, a filter plate is installed on one side of the moving ring close to the water inlet pipe.

[0015] By adopting the above technical solutions, the beneficial effects obtained by the present utility model are as follows:

[0016] The water inlet pipe of the present utility model is connected to the internal thread of the assembly pipe through the external thread to form a sealed connection part. The assembly pipe is fixedly connected to the drain pipe to ensure that the water inlet pipe, the assembly pipe and the drain pipe form a channel.

[0017] The filter plate is fixed on the moving ring, and the moving ring slides in the assembly pipe. The cooperation between the guiding seat and the guiding groove ensures the stable movement of the moving ring. When dirt flows in through the water inlet pipe, the filter plate will filter the dirt.

[0018] As the dirt on the filter plate gradually increases, the filtering ability will decline, and the accumulation of dirt leads to an increase in the impact force on the filter plate.

[0019] This impact force pushes the moving ring, compresses the telescopic spring, and makes the contact rod contact the pressure sensor.

[0020] After the pressure sensor detects a pressure change, it triggers an external alarm to sound an alarm, prompting the staff to replace the filter element. Through the pressure sensor and the alarm system, the status of the filter plate can be monitored in real time, avoiding the trouble of manual inspection, improving work efficiency and safety. The clogging situation of the filter plate will be prompted by the alarm, and the staff can perform maintenance and replacement in a timely manner, avoiding potential problems caused by long-term use. The sewage cut-off valve can not only perform sewage discharge operations efficiently, but also automatically sound an alarm when the filtering function fails, ensuring the reliable operation and timely maintenance of the system.
