Description

Technical Field

[0001] The utility model relates to the field of valve equipment, in particular to an automatic valve with water hammer protection. Background Art

[0002] For an automatic valve with water hammer protection, such a valve is specifically designed to prevent the occurrence of water hammer phenomenon. Through its unique mechanism, when a negative pressure condition appears in the pipeline, it can quickly intervene and introduce external air to fill this negative pressure area, thereby effectively curbing the occurrence of water hammer phenomenon and protecting the safe and stable operation of the pipeline system.

[0003] When installing this water hammer prevention valve, a flange is usually used as a connecting piece to firmly install it between pipelines. It should be noted that although the valve is tightly connected to the pipeline through the flange at the initial stage of installation, after the installation is completed, the valve itself may be in a relatively suspended state, that is, its main body is not directly supported on the pipeline or other fixed structures. Due to the continuous flow of water in the pipeline, the two sides of the valve will be affected by the impact force of the water flow. Although these forces may not be significant during daily operation, over time and with frequent water flow fluctuations, they will gradually affect the stability of the valve. Long-term stress may cause the connection between the valve and the pipeline to loosen. In order to reduce the stress on the valve in the suspended state and ensure its long-term stable operation, an automatic valve with water hammer protection is proposed. Summary of the Utility Model

[0035] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6, the automatic valve with water hammer protection in this application is mainly composed of a water hammer prevention valve body 1 and connecting pipe fittings 101 and other structures. Among them, the water hammer prevention valve body 1 is connected between the connecting pipe fittings 101 by a flange. The bottom of the water hammer prevention valve body 1 is connected to the connecting pipe fittings 101. By inserting the support rod 2 movably therein and arranging an adjustable stable support 3 at the bottom of the support rod 2, the bottom surface of the stable support 3 can support the entire water hammer prevention valve body 1 on the contact surface of a certain installation area, thereby reducing the stress condition of the water hammer prevention valve body 1 in a suspended state, ensuring its stable operation in the long-term state, and also improving the stability of the connection.

[0036] In this application, an adjustment screw 301 is also provided. A slot is opened in the stable support 3. One end of the adjustment screw 301 is vertically movably installed in the slot of the stable support 3 through a bearing, and the other end is sleeved with the support rod 2 in a threaded manner. Just fix the handle of the adjustment screw 301 of the stable support 3 and turn it, and while driving the adjustment screw 301 to rotate, the support rod 2 can be moved up and down, thereby adjusting the distance between the support rod 2 and the stable support 3, improving the applicability, and can be adjusted according to the usage requirements.

[0037] In this application, a tooth structure 302 is also provided. The tooth structure 302 is evenly glued to both sides of the stable support 3. When contacting the soil, a part of the tooth structure 302 that points downward can be driven to insert therein, thereby improving the stability of the support surface of the stable support 3, ensuring the overall application effect, and at the same time, for the tooth structure 302 glued on, it can be removed according to different support surfaces.

[0038] In this application, a limit outer frame 4 is also provided. The limit outer frame 4 is fixedly installed at both ends of the support rod 2, so that the valve body bracket 102 can be located between the support rod 2 and the limit outer frame 4 and move up and down following the support rod 2. While limiting the valve body bracket 102, the limit outer frame 4 and the valve body bracket 102 are fastened by bolts, thereby assembling the two and facilitating the subsequent disassembly operation.

[0039] It should also be noted that a plurality of reserved openings 401 are evenly opened on the limit outer frame 4. Among them, when the valve body bracket 102 is located between the limit outer frame 4 and the support rod 2, one end of the reserved opening 401 penetrates through the valve body bracket 102 and extends into the interior of the support rod 2. At this time, when assembling the limit outer frame 4 and the valve body bracket 102, they can be installed at different heights. Just align the holes on the limit outer frame 4, the valve body bracket 102, and the support rod 2 and install bolts, which improves the convenience of operation.

[0040] In this application, a limiting clamping plate 5 and a stable convex layer 501 are also provided. After the overall structure of the stable support 3 is installed, the limiting clamping plates 5 are arranged on both sides thereof, so that the outside of the flange connecting the water hammer prevention valve body 1 and the connecting pipe fitting 101 is subjected to a limiting operation, so as to further improve the connection stability between the water hammer prevention valve body 1 and the connecting pipe fitting 101 after installation; the stable convex layer 501 is arranged on the surface of the inner side of the limiting clamping plate 5 in contact with the flange of the connecting pipe fitting 101.

During the process of pulling the handle 505 outwards to drive the limiting clamping plate 5 to move, the stable rod 6 is also driven to move in the compression spring 601 in the same direction to ensure the stability during movement. At the same time, the stable inner groove 602 is arranged between the limiting clamping plate 5 and the stable support 3 and surrounds one end of the stable rod 6 extending outside the compression spring 601. In this way, when the limiting clamping plate 5 is pulled outwards, the stable inner groove 602 is also pulled, so as to adjust the distance between the limiting clamping plate 5 and the flange of the connecting pipe fitting 101 while facilitating the unlocking state, so as to improve the applicability.

[0045] In this application, a connecting member 7 is also provided.
