Detailed Implementation

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments listed in the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0026] Example: A novel gun-type water hammer pump, such as Figure 1 As shown, the system consists of an inlet valve 4, a drain valve 3, a center valve 2, and an outlet valve 5 arranged in series along the water inlet direction. Above the center valve 2, there is a pressure tank 1 connected to the center valve 2. The center valve 2 is equipped with a pressure gauge 6 and a safety valve 7.

[0027] The drain valve 3 is an important component of the water hammer pump and is key to generating the water hammer effect. It includes a valve disc shaft 301, a nut 302, a counterweight 303, a limit nut 304, a bracket 305, a valve top cover 306, a second valve disc 307, a limit nut 308, a wear-resistant bushing 309, and a drain valve body 310. The nut 302, counterweight 303, limit nut 304, bracket 305, valve top cover 306, second valve disc 307, limit nut 308, and wear-resistant bushing 309 are all fixed in series on the valve disc shaft 301. Except for the bracket 305, valve top cover 306, and drain valve body 310, the other components can move up and down with the valve disc shaft 301. The second valve disc 307 is made of polyester fiber or other non-metallic materials. During operation, the second valve disc 307 will strongly impact the sealing surface on the valve top cover 306 under the action of water flow. Since the valve top cover 306 is usually made of metal, this avoids metal-to-metal impacts and reduces noise. Simultaneously, the contact surface between the second valve disc 307 and the valve top cover 306 is a conical sealing surface, resulting in a better seal. When there are two or more drain valves, the opening and closing speed of the drain valves can be adjusted by changing the number of counterweights 303, allowing each drain valve to operate synchronously and achieve maximum water output. When the water level difference between the water source and the water hammer pump inlet is small, the drain valve 2 can be placed horizontally. A spring is also required between the bracket 305 and the second valve disc 307 to keep the second valve disc 307 open when there is no or minimal water leakage.

[0028] The central valve 2, also known as the pressure relief valve, is an important component of the water hammer pump and is used in conjunction with the drain valve 3. When subjected to the force of water hammer, it works with the water hammer force to pressurize water into the pressure tank 1. Simultaneously, when subjected to back pressure from the water supply pipe, it applies pressure in the reverse direction to the inlet pipe, allowing the drain valve 3 to reopen. The central valve 2 consists of a central valve body 201, a first valve disc 202, a fixing screw 203, a spring 204, a stainless steel valve disc 205, and a central valve top cover 206. The stainless steel valve disc 205 is a T-shaped shaft-like part. The diameter of the first valve disc 202 is greater than or equal to the diameter of the stainless steel valve disc 205. The fixing screw 203 fixes the first valve disc 202 to the stainless steel valve disc 205. The spring 204, which is fitted on the shaft of the stainless steel valve disc 205, generates elastic force to keep the first valve disc 202 and the sealing surface on the central valve body 201 in a flat or conical manner, maintaining a sealed state. The stainless steel valve disc 205 and the central valve top cover 206 slide axially. During operation, the impact noise between the first valve disc 202, made of high-strength non-metallic material, and the sealing surface made of metal is greatly reduced, while also extending its service life. The central valve body 201 is equipped with a fixed support foot 2011, which can be used to fix the entire water hammer pump with bolts.

[0029] Since both valves use threaded connection structures, the valve cores of the center valve 2 and the drain valve 3 are easily damaged parts and can be replaced by the user.

[0030] The pressure tank 1 is equipped with an air bladder 102 and a valve core 103. The air bladder 102 is located in the upper part of the tank body 101. The bottom of the tank body 101 has an outlet that connects to the central valve 2. The air bladder 102 is inflated from the outside through the valve core 103. The purpose of setting up the air bladder is to maintain a certain pressure inside the pressure tank at all times, thereby maintaining a stable water output.

[0031] Operating principle:

[0032] 1. After the inlet valve is opened, the water flow is affected by the pressure difference and flows from the high point to the water hammer pump along the inlet pipe. It flows out from the opened drain valve. The water flow will impact the valve disc (i.e., the second valve disc) of the drain valve and drive the valve disc (i.e., the second valve disc) to move upward until it fits against the sealing surface on the valve top cover, forcing the drain valve to close instantly.

[0033] 2. When the drain valve is closed momentarily, the water in the pipe continues to move forward due to water pressure and inertia, impacting and transmitting pressure to the water flow ahead. The water flow below the drain valve disc (i.e., the second valve disc) experiences the greatest transmitted and compressive force, which accumulates and generates enormous pressure, which is then released to the surrounding area. This phenomenon is called the water hammer effect.

[0034] The pressure generated by the water hammer effect is enormous but brief. When this brief pressure is released, it collides with the pressure of the water flow inside the pipe, causing vibration and weakening some of the water flow pressure. When the pressure reaches the drain valve (the second valve), it releases and cancels out the incoming water flow. At the moment of cancellation, the drain valve (the second valve) reopens due to the lack of support, and water flows out again through the open valve. This then causes the drain valve to close again, generating the water hammer effect once more, and the cycle begins again. This cycle repeats continuously, ensuring a continuous flow of water to higher ground.

[0035] Figures 5 to 11 The embodiments shown are merely common examples of this utility model and should not be construed as limiting the scope of this utility model. Equivalent variations made based on this utility model are still within the scope of this utility model.
