Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a flow regulating valve. Background Art

[0002] Currently, the transportation of gaseous or liquid media is primarily carried out using pipelines, with valves between them controlling the flow rate and acting as switches. Flow control valves are currently used on both water-using equipment and water pipelines to control the flow of media in the pipeline. These flow control valves operate by increasing or decreasing the flow cross-section when the valve is opened or closed, thereby increasing or decreasing the amount of fluid passing through. Traditional flow control valves can only provide flow regulation. Larger particles of fixed impurities or soft impurities inherent in the fluid medium can easily cause blockage and damage to terminal equipment. Traditionally, a filter has been installed in the outlet pipe of the flow control valve, which undoubtedly increases manufacturing costs and is inconvenient to maintain. Utility Model Content

[0008] The filter assembly is arranged in the filter cavity and is used to filter the fluid medium flowing to the water outlet pipeline.

[0009] As a preferred solution, the filter assembly includes a filter holder arranged in the filter cavity and a filter screen arranged at one end of the filter holder, and the filter screen is cooperatively arranged at the inner end of the outlet pipe.

[0010] As a preferred solution, a connecting port is provided between the valve chamber and the filter chamber, and the filter assembly further includes a sealing gasket provided at the other end of the filter bracket. The other end of the filter bracket is provided with an arc-shaped portion, and the sealing gasket cooperates to close at the connecting port. After the regulating valve core opens the valve port, the sealing gasket is elastically deformed toward the side of the arc-shaped portion due to the pressure impact of the fluid medium.

[0011] As a preferred solution, the filter bracket includes a plurality of bracket plates arranged in an intersecting manner and an annular frame connected to one end of the plurality of bracket plates, the filter mesh is sleeved on the annular frame, the arc-shaped portion includes a plurality of arc-shaped edges arranged on the other end of the plurality of bracket plates, and the filter bracket is provided with a connecting rod connected to the sealing gasket at the top end where the plurality of arc-shaped edges intersect.

[0016] As a preferred solution, the valve core seat is provided with a locking hole extending radially along the guide hole and connected to the guide hole, and a locking member is passed through the locking hole to form a limiting fit with the regulating valve core.

[0017] As a preferred solution, at least one mounting buckle is provided on the valve body.

[0018] Compared with the existing technology, the technical solution of this utility model has the following advantages:

[0019] 1. In the flow regulating valve provided by the present invention, the outlet connector can be detachably installed on the valve body, and the filter assembly is installed in the filter cavity formed between the outlet connector and the valve body. The filter assembly can eliminate and filter out impurities in the fluid medium, thereby protecting the smooth and normal operation of the terminal equipment, reducing the failure rate and maintenance frequency of various equipment, and reducing equipment maintenance costs. The flow regulating valve using this technical solution can realize the built-in installation of the filter assembly at the outlet position, so that it not only has its own flow regulating function, but also has the ability to filter the medium, thereby avoiding the traditional method of externally connecting a filter device to the outlet of the flow regulating valve, which is conducive to reducing costs. This filter assembly is relatively simple to install and disassemble, and is convenient for subsequent maintenance. It can ensure that the fluid medium can only flow into the outlet connector after being filtered by the filter assembly, thereby ensuring the filtering effect of the product and improving the product's performance and service life.

[0020] 2. In the flow regulating valve provided by the utility model, according to the filter assembly, it is composed of a filter bracket, a sealing gasket and a filter screen. This sealing gasket is cooperated to close the connecting port between the valve chamber and the filter chamber to prevent water backflow. When the regulating valve core moves to open the valve port, the fluid medium flows through the connecting port to the outlet joint and impacts the sealing gasket, causing the sealing gasket to be elastically deformed toward the arc-shaped part of the filter bracket under the impact, thereby releasing the blockage of the connecting port position, allowing the fluid medium to enter the outlet pipe after being filtered by the filter screen. By designing the arc-shaped part on the filter bracket, it just plays a buffering role for the elastic deformation of the sealing gasket, and after the regulating valve core closes the valve port, the sealing gasket restores its deformation and re-covers the connecting port position.

[0021] 3. In the flow regulating valve provided by the present invention, the regulating valve core is connected to the guide hole of the valve core seat through a threaded structure, and the regulating valve core is moved up and down along the guide hole by rotating the regulating valve core, thereby driving the conical sealing part to gradually open or close the valve port to realize the flow regulation function. A second sealing ring is provided between the regulating valve core and the inner wall of the guide hole, and a third sealing ring is provided between the valve core seat and the valve body. With this structural setting, the second sealing ring plays a sealing role between the regulating valve core and the guide hole, and the third sealing ring plays a sealing role at the connection position between the valve core seat and the valve body, so as to prevent leakage accidents and ensure the safety of product use.

[0022] 4. In the flow regulating valve provided by the present invention, the locking member is radially inserted into the guide hole to press against the regulating valve core, so that a limit fit is formed between the locking member and the regulating valve core to prevent the regulating valve core from being misoperated and displaced, thereby playing a limit locking role on the regulating valve core.

[0032] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0033] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0034] Example

[0035] The present embodiment will be described in detail below with reference to the accompanying drawings:

[0036] This embodiment provides Figure 1-5 A flow regulating valve shown, comprising:

[0037] The valve body 1 includes a valve cavity 11, an inlet pipe 41, and a valve port connected between the inlet pipe 41 and the valve cavity 11;

[0038] The regulating structure includes a regulating valve core 2 provided on the valve body 1 and reciprocating along the axial direction of the valve port. The regulating valve core 2 has a conical sealing portion 21 that penetrates into the valve port.

[0039] An outlet connector 3 is detachably mounted on the valve body 1 and is provided with an outlet pipe 31 . The outlet connector 3 is connected to the valve body 1 to form a filter chamber 12 communicating with the valve chamber 11 .

[0040] The filter assembly 5 is arranged in the filter cavity and is used to filter the fluid medium flowing to the water outlet pipe.

[0041] The above-mentioned implementation mode is the core technical solution of this embodiment. According to the outlet connector 3, it can be detachably installed on the valve body 1, and the filter assembly 5 is installed in the filter cavity 12 formed between the outlet connector 3 and the valve body 1. The filter assembly 5 can eliminate and filter out impurities in the fluid medium, thereby protecting the smooth and normal operation of the terminal equipment, reducing the failure rate and maintenance frequency of various equipment, and reducing equipment maintenance costs. The flow regulating valve using this technical solution can realize the built-in installation of the filter assembly at the outlet position, so that it not only has its own flow regulation function, but also has the ability to filter the medium, thereby avoiding the traditional method of externally connecting a filter device to the outlet of the flow regulating valve, which is conducive to reducing costs. This filter assembly 5 is relatively simple to install and disassemble, and is convenient for subsequent maintenance. It can ensure that the fluid medium can only flow into the outlet connector 3 after being filtered by the filter assembly 5, thereby ensuring the filtering effect of the product and improving the product's performance and service life.

[0042] The following combination Figure 3-5 The specific setting method of the filtering component is described in detail:

[0043] The filter assembly 5 includes a filter holder 51 arranged in the filter chamber 12, a filter screen 52 arranged at one end of the filter holder 51, and a sealing gasket 53 arranged at the other end of the filter holder 51. The filter screen 52 is arranged at the inner end of the outlet pipe 31. A connection port 13 is provided between the valve chamber 11 and the filter chamber 12. The sealing gasket 53 is closed at the connection port 13 to prevent water from flowing back. The other end of the filter holder 51 is provided with an arc portion 510. This structural arrangement is effective in the adjustment of the filter. After the valve core 2 opens the valve port, the fluid medium will impact the sealing gasket 53 when flowing through the connecting port 13 to the outlet connector 3, causing the sealing gasket 53 to be elastically deformed toward the arc portion 510 due to the pressure impact of the fluid medium. This releases the blockage of the connecting port 13, allowing the fluid medium to enter the outlet pipe 31 after being filtered by the filter screen 52. The arc portion 510 is designed to act as a buffer for the elastic deformation of the sealing gasket 53, and after the regulating valve core 2 closes the valve port, the sealing gasket 53 recovers its deformation and re-blocks the connecting port 13. For the disassembly and replacement of the filter assembly 5, only the outlet connector 3 is removed from the valve body 1, and then the filter assembly 5 can be removed from the filter chamber 12 for replacement, and then reinstalled on the valve body together with the outlet connector 3. The installation and disassembly are convenient, which helps to improve the installation efficiency.

[0044] As a preferred embodiment, Figure 5 As shown, the filter bracket 51 includes a plurality of bracket plates 511 arranged to intersect and an annular frame 512 connected to one end of the plurality of bracket plates 511, the filter screen 52 is sleeved on the annular frame 512, the arc portion 510 includes a plurality of arc edges arranged on the other end of the plurality of bracket plates 511, and the filter bracket 51 is provided with a connecting rod 54 connected to the sealing gasket 53 at the top end where the plurality of arc edges intersect, and a limiting boss is provided at the end of the connecting rod 54 to form a limiting cooperation with the sealing gasket 53. With this structural arrangement, the filter The filter chamber 12 is divided by multiple support plates 511 to form multiple diversion channels. The sealing gasket 53 is elastically deformed when impacted by the fluid medium and rests on multiple arc edges. The arc edges support the sealing gasket 53, thereby opening the connection port 13 to allow the fluid medium to enter the filter chamber 12, and then flow to the side of the filter screen 52 through multiple diversion channels. The filter screen 52 can eliminate impurities in the filtered flow medium to ensure that the fluid medium flows into the outlet pipe 31 after being filtered by the filter screen 52.

[0045] like Figure 3 As shown, the outlet joint 3 is connected to one end of the valve body 1 in the length direction through a threaded structure, and a first sealing ring 14 is provided between the outlet joint 3 and the valve body 1. The sealing of the connection position between the outlet joint 3 and the valve body 1 is achieved by the first sealing ring 14. The flow regulating valve of this embodiment is used to regulate the flow of water, and an outlet joint 3 is formed at the bottom of the valve core. The inlet pipe 41 is extended and arranged in the outlet joint 3. The extension direction of the inlet pipe 41 is perpendicular to the extension direction of the outlet pipe 31, thereby forming a water path that passes through the inlet pipe 41, the valve cavity 11, the filter cavity 12 and the outlet pipe 31 in sequence. The outlet joint and the inlet joint can realize a quick installation connection between the flow regulating valve and the pipeline.

[0046] In this embodiment, the adjustment structure includes a valve core seat 6 detachably connected to the valve body 1, and a guide hole penetrating the valve core seat 6 and opposite to the valve port, the guide hole and the valve port are axially aligned, such a valve core seat 6 is threadedly connected to the valve body 1, and the regulating valve core 2 is connected to the guide hole through a threaded structure. Specifically, an external thread is provided on the regulating valve core 2, and an internal thread matching the external thread is provided on the inner wall of the guide hole, so that the regulating valve core 2 can be moved relative to the valve core seat 6 by means of threaded transmission. One end of the regulating valve core 2 is provided with the conical sealing portion 21, and the other end extending out of the top of the valve body 1 is provided with a knob 7. By rotating the regulating valve core 2, it moves up and down along the guide hole for adjustment, thereby driving the conical sealing portion 21 to gradually open or close the valve port, thereby achieving the function of flow regulation. In order to ensure the sealing performance of the product, a second sealing ring 15 is provided on the regulating valve core 2 and is in sealing contact with the inner wall of the guide hole. A third sealing ring 16 is provided between the valve core seat 6 and the valve body 1. The second sealing ring 15 seals the regulating valve core 2 and the guide hole, and the third sealing ring 16 seals the connection position between the valve core seat 6 and the valve body 1 to prevent leakage accidents, improve the product protection level, and ensure the safety of product use.

[0047] Combine Figure 1 and Figure 3 As shown, the valve core seat 6 is provided with at least one locking hole extending radially along the guide hole and connected to the guide hole, and a locking member 8 is passed through the locking hole to form a limiting fit with the regulating valve core 2. The locking hole is a threaded hole set on the valve core seat 6, and the locking member 8 is matched with a locking screw connected to the threaded hole. This structural arrangement allows the locking member 8 to radially penetrate into the guide hole to press the regulating valve core 2, so that a limiting fit is formed between the locking member 8 and the regulating valve core 2 to prevent the regulating valve core 2 from being displaced due to misoperation, thereby playing a limiting locking role on the regulating valve core 2 to ensure that the flow rate of the flow control valve is continuously and stably output.

[0048] To facilitate installation of the flow control valve, the valve body 1 is provided with at least one mounting clip 9, which can be used to secure the valve body 1 to a predetermined mounting position, thereby enabling quick installation and fixation of the flow control valve. Of course, this flow control valve can also be installed and fixed using other methods such as screw fixation or adhesive fixation, which will not be detailed here.

[0049] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
