Description

Technical Field

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

[0002] A balance valve is a valve with special functions, used to regulate, divert or limit the fluid flow rate of a system to ensure the fluid flow balance between various parts of the pipeline system. It is widely used in fields such as heating, air conditioning, and industrial fluid transportation, helping to solve the problem of hydraulic imbalance in the system, improving the energy efficiency and operation stability of the system. The hydraulic balance valve is widely used in fields such as building, industry, and household water supply, such as the water pressure and flow regulation of floors and water use points in building water supply systems, the water pressure and flow control of industrial water supply systems, and the water pressure and flow stability of household water supply systems.

[0003] After retrieval, the existing patent (publication number: CN212091078U) discloses a static hydraulic balance valve, including a valve body, a valve stem, a valve core and a handwheel, and also includes a filtering module. The filtering module includes a module frame, a filter screen and a rotating handle. The outer periphery of the module frame is circular and is provided with a frame thread for cooperating with the installation thread. The module frame is coaxially and penetratingly provided with a filtering hole for fixing the filter screen. The end of the module frame facing the inflow section is provided with a semi-circular handle groove around it. The rotating handle is adapted to the shape of the handle groove and is respectively hinged at both ends to the handle groove. When the rotating handle flips relative to the handle groove, it has a storage state of being stored in the handle groove and an operation state perpendicular to the storage groove and used for rotating the module frame. However, in this way, when the filter screen needs to be cleaned, hands or tools need to be inserted into the valve body, which increases the complexity and difficulty of the operation. During the operation, if the operation is improper or the tool is used improperly, it may cause accidental injuries, such as scratches and pinches.

[0004] Therefore, it is necessary to provide a new hydraulic balance valve to solve the above technical problems. Summary of the Utility Model

[0005] To solve the above technical problems, the utility model provides a hydraulic balance valve.

[0006] The hydraulic balance valve provided by the utility model includes: a valve body, and a filtering device is installed at the inflow end of the valve body;

[0007] The filtering device includes a mounting ring. Both ends of the outer side of the upper half of the mounting ring are fixedly connected with arc-shaped bars. The tops of the two arc-shaped bars are both fixedly connected with arc-shaped plates. An arc-shaped block is arranged between the two arc-shaped bars. A buckle member is arranged between the two arc-shaped plates. The bottom surface of the buckle member is fixedly connected with one end of the top surface of the arc-shaped block;

[0008] An installation opening is provided in the upper half of the corresponding position between the valve body and the installation ring, and an arc-shaped groove adapted to the arc-shaped block is provided in the lower half of the corresponding position between the valve body and the installation ring.

[0009] Preferably, the longitudinal section of the arc-shaped strip and the arc-shaped plate after being fixedly connected is an L-shaped structure.

[0010] Preferably, the buckle includes a bottom box, a spring, a telescopic frame and an inclined block. The bottom surface of the bottom box is fixedly connected to the top surface of the arc-shaped block. One end of the inner bottom wall of the bottom box is fixedly connected to one end of the spring, and the other end of the spring is fixedly connected to the inclined block. The bottom surface of the inclined block is fixedly connected to the top surface of the telescopic frame, and the telescopic frame is arranged inside the bottom box.

[0011] Preferably, a limiting block is fixedly connected to one end of the two arc-shaped strips and the two arc-shaped plates, and the limiting block is of an inverted T-shaped structure.

[0012] Preferably, sealing gaskets are installed on the side wall of the installation ring, the outer side wall of the arc-shaped strip, both ends of the arc-shaped strip, the outer side wall of the arc-shaped plate and both ends of the arc-shaped plate.

[0013] Preferably, at the position where the valve body is provided with the installation opening, a fixing plate is fixedly connected to the end far from the limiting block, and a through groove adapted to the size of the inclined block is provided at the center of the fixing plate.

[0014] Compared with the related art, the hydraulic balance valve provided by the present invention has the following beneficial effects:

[0015] The present invention provides a hydraulic balance valve. The filtering device is installed on the valve body through the installation opening. The buckle is slid, and the buckle drives the arc-shaped block to slide in the channel formed by the installation ring, the arc-shaped strip and the arc-shaped plate to the arc-shaped groove opened in the valve body, completing the installation of the filtering device. By installing the filtering device at the inlet end of the valve body, impurities in the water entering the valve body, such as particles and sand, can be effectively removed. This can not only protect the internal parts of the valve body from wear, but also ensure the normal operation of the hydraulic system, avoiding performance degradation or failure caused by impurity blockage. By sliding the buckle, the filtering device can be conveniently and quickly installed on the valve body. The buckle drives the arc-shaped block to slide in the channel formed by the installation ring, the arc-shaped strip and the arc-shaped plate, and finally enters the arc-shaped groove opened in the valve body to complete the entire installation process. Since the filtering device is highly detachable and has a relatively simple structure, its maintenance cost is relatively low. Users can perform operations such as cleaning and replacing the filter screen by themselves without the participation of professional technicians, reducing the maintenance cost and time cost. This installation method does not require complex tools or equipment, greatly improving the installation efficiency. Description of the Drawings

A buckle 11 is arranged between the two arc-shaped plates 5. The bottom surface of the buckle 11 is fixedly connected to one end of the top surface of the arc-shaped block 6. At the upper half of the corresponding position of the valve body 1 and the installation ring 3, an installation opening is provided. At the lower half of the corresponding position of the valve body 1 and the installation ring 3, an arc-shaped groove adapted to the arc-shaped block 6 is provided. An installation opening is provided at the upper half of the valve body 1 for installing the filtering device. At the corresponding position of the lower half of the valve body 1, an arc-shaped groove adapted to the arc-shaped block 6 is provided to ensure the stability and sealing performance after the installation of the filtering device. The longitudinal section after the arc-shaped strip 4 and the arc-shaped plate 5 are fixedly connected is an L-shaped structure. The buckle 11 includes a bottom box 7, a spring 8, a telescopic frame 9 and an inclined block 10. The bottom surface of the bottom box 7 is fixedly connected to the top surface of the arc-shaped block 6. The inner bottom wall of the bottom box 7 is fixedly connected to one end of the spring 8. The other end of the spring 8 is fixedly connected to the inclined block 10. The bottom surface of the inclined block 10 is fixedly connected to the top surface of the telescopic frame 9. The telescopic frame 9 is arranged inside the bottom box 7. At one end of the two arc-shaped strips 4 and the two arc-shaped plates 5, a limiting block 14 is fixedly connected.
