Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a low-noise wastewater valve. Background Technology

[0002] Wastewater valves are typically integrated into the water circuit board of equipment such as water purifiers, becoming part of the overall water system along with other water circuit components such as inlet solenoid valves and flushing solenoid valves. In wastewater valves, the water flow, after passing through the throttling pipe, often generates significant noise due to the excessively high flow rate. Currently, wastewater valves lack noise reduction measures, resulting in high-pressure water flow noise exceeding 45 decibels through the throttling pipe, exceeding noise standards and leading to a poor user experience. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art by providing a low-noise wastewater valve that can reduce water flow noise and has the functions of throttling and noise reduction.

[0004] The technical solution of this utility model is as follows: A low-noise wastewater valve includes a valve seat and an electromagnetic control device. The valve seat is provided with an inlet channel and an outlet channel, and a diaphragm is installed. The diaphragm is provided with a first through hole and a second through hole. The valve seat has an upper water chamber above the diaphragm. The first through hole connects the upper water chamber and the inlet channel. The electromagnetic control device is provided with a moving iron core. The upper end of the second through hole is correspondingly arranged with the moving iron core. The moving iron core can move up and down to open or close the second through hole. The lower end of the second through hole is connected to the outlet channel through a cavity. The diaphragm cooperates with the upper end of the cavity. The valve seat is provided with a silencing cavity. The silencing cavity is provided with a throttling pipe and a silencing plate. The throttling hole on the throttling pipe keeps the inlet channel and the silencing cavity always connected. The silencing hole on the silencing plate keeps the silencing cavity and the cavity always connected.

[0005] Using the above technical solution, water flows into the silencing cavity through the throttling orifice on the throttling pipe and accumulates inside. This increases the water pressure within the cavity, causing the water to flow out through the silencing orifice, thus reducing the water flow velocity and noise. These multiple effects reduce water flow velocity and pressure, significantly lowering noise levels and bringing the overall water flow noise below a certain decibel level.

[0006] A further feature of this invention is that the silencing plate is provided with multiple silencing holes, which are staggered from the throttling holes.

[0007] With the above-mentioned further configuration, the silencing holes and throttling holes are staggered, which prevents water from spraying out directly from the silencing holes and allows the water in the cavity to flow out evenly from multiple silencing holes, reducing the flow rate of the water and lowering the noise.

[0008] A further feature of this invention is that: an opening is provided on one side wall of the silencing cavity, and an installation port is provided on the side wall of the valve seat at the position corresponding to the opening of the silencing cavity; a plug is installed at the installation port, and the silencing plate abuts against the opening of the silencing cavity through the plug.

[0009] With the further configuration described above, the plug can be easily installed and removed via the cavity opening on one side of the silencing chamber and the corresponding mounting port on the valve seat sidewall, thus enabling the installation and removal of the silencing plate. This design facilitates cleaning or replacement of the silencing plate, ensuring the durability of the silencing effect. Simultaneously, the plug also provides a sealing function, preventing water leakage from the mounting port and ensuring the normal operation of the valve.

[0010] A further feature of this invention is that the silencing plate abuts against the convex step on the inner wall of the silencing cavity, and a side push rod 0 is provided between the silencing plate and the plug.

[0011] With the above-mentioned further configuration, the silencer plate can be firmly abutted against the raised step on the inner wall of the silencer cavity. The side push rod effectively prevents the plug and the silencer plate from being tightly fitted, thereby preventing the silencer hole from being blocked, ensuring smooth water flow and avoiding the problem of water outlet obstruction.

[0012] A further improvement of this invention is that the plug and the valve seat are connected by ultrasonic welding, threaded connection, or screw connection.

[0013] With the above-described further modifications, the connection between the plug and the valve seat can be varied and robust. Ultrasonic welding ensures a seamless connection between the plug and the valve seat, improving overall sealing performance; threaded and screw connections facilitate installation and disassembly while also providing good sealing. This versatility in connection methods allows this invention to adapt to different installation environments and requirements, improving the valve's applicability and reliability.

[0014] A further feature of this invention is that the silencing cavity is located at the bottom of the cavity, the silencing plate is located on one side wall of the silencing cavity, and the throttling tube is located at the top of the silencing cavity.

[0015] With a further refinement, the silencing chamber is cleverly positioned at the bottom of the cavity, while the silencing plate is ingeniously mounted on one side wall of the chamber, and the throttling pipe is located at the top. This structural design not only optimizes the internal structure of the valve but also effectively reduces noise during wastewater discharge. The silencing chamber absorbs and dissipates sound waves generated by the impact of water flow, while the silencing plate further enhances the noise reduction effect, making the wastewater valve quieter during operation.

[0016] A further improvement of this invention is that the inlet channel and the outlet channel are located on the same side of the valve seat.

[0017] With the above-mentioned further configuration, the inlet and outlet channels are located on the same side of the valve seat. This layout design makes the water flow path more compact and facilitates the installation and maintenance of the valve. Attached Figure Description

The upper end of the second through hole 32 is correspondingly arranged with the moving iron core 21. The moving iron core can move up and down to open or close the second through hole. The lower end of the second through hole 32 is connected to the water outlet channel 12 through the cavity 4. The diaphragm 3 is fitted with the upper end of the cavity 4. The valve seat 1 is provided with a silencing cavity 5. A throttling pipe 6 and a silencing plate 7 are fixedly or integrally arranged on the silencing cavity 5. The throttling hole 61 on the throttling pipe 6 keeps the water inlet channel 11 and the silencing cavity 5 connected. The silencing hole 71 on the silencing plate 7 keeps the silencing cavity 5 and the cavity 4 connected. The silencing plate 7 is provided with multiple silencing holes 71, which can be two, three or more, and the silencing holes 71 are staggered from the throttling holes 61. The silencing cavity 5 is located at the bottom of the cavity 4, the silencing plate 7 is located on one side wall of the silencing cavity 5, and the throttling pipe 6 is located at the upper part of the silencing cavity 5.

[0028] Specifically, the silencing cavity 5 has an opening 51 on one side wall, and the valve seat 1 has an installation port 14 on its side wall corresponding to the silencing cavity opening 51. A plug 8 is installed at the installation port 14, and the silencing plate 7 abuts against the opening of the silencing cavity 5 via the plug 8.

[0030] The working principle of this utility model:

[0031] When the power is off, the moving iron core moves downward under the action of the return spring, closing the second through hole. At this time, the diaphragm moves downward under the action of water pressure, sealing with the upper end of the cavity. The water in the inlet channel flows into the outlet channel through the throttling orifice, which is the throttling state. When the power is on, the moving iron core moves upward under the action of magnetic force, opening the second through hole. At this time, the diaphragm moves upward under the action of water pressure, directly connecting the inlet and outlet channels, which is the flushing state. The water flows into the silencing cavity through the throttling orifice on the throttling pipe and accumulates in the cavity. The water pressure in the cavity increases, and the water flows out from the silencing orifice. The flow rate of the water decreases, reducing noise.

[0032] It should be noted that in the description of this utility model, all directional indicators (such as up, down, forward, backward, etc.) are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
