Description

Technical Field

[0001] This utility model relates to the field of pipeline protection equipment technology, and in particular to a water pipe pressure buffer device. Background Technology

[0002] In a closed-loop pure water cooling system, changes in ambient and coolant temperature cause volume variations due to coolant expansion and contraction, leading to pressure fluctuations. When the coolant temperature rises, it expands, causing pressure increases within a specific space. Conversely, when the coolant temperature drops, it contracts, causing pressure decreases. These pressure fluctuations result in flow rate changes, leading to system instability. Therefore, stabilizing the overall coolant system pressure is essential.

[0003] Currently, the buffer device of water cooling system mainly adopts the form of expansion tank. This device needs to be injected with gas regularly during use to ensure the expansion effect of the air bladder inside the expansion tank, which increases the later maintenance cost.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] To address the aforementioned shortcomings, the purpose of this utility model is to provide a water pipe pressure buffering device. This device can buffer the pressure of the water pipe by setting a pressure buffering valve, and at the same time, it is equipped with a bypass structure to ensure that the water flow generated during the impact can be bypassed, thereby optimizing the pressure buffering effect.

[0006] To achieve the above objectives, this utility model provides a water pipe pressure buffer device, comprising: The valve body has an inlet pipe and an outlet pipe at both ends that are connected to water pipes; A branch pipe spanning the inlet and outlet pipes is provided, with a buffer assembly slidably installed inside the branch pipe to seal it. The buffer assembly is slidably connected to a sealing head inside the branch pipe. The sealing head seals the branch pipe when the water pressure is lower than a predetermined value. A buffer element is provided between the sealing head and the branch pipe to buffer the impact force of the sealing head.

[0007] In one embodiment, a sliding sleeve is provided in the middle section of the branch pipe, and the buffer assembly is slidably connected to the inside of the sliding sleeve, wherein the diameter of the sliding sleeve is larger than the diameter of the branch pipe.

[0008] In one embodiment, the sliding sleeve is provided with a sealing part at one end of the water inlet pipe, and the front end of the sealing head is provided with a sealing bevel corresponding to the sealing part.

[0009] In one embodiment, the sidewall of the sealing head is provided with a plurality of evenly arranged water-permeable holes, which are located on the sealing inclined side.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] See Figure 1 , Figure 2 and Figure 3This utility model provides a water pipe pressure buffer device, which includes a valve body 3 with an inlet pipe and an outlet pipe at both ends connected to a water pipe 2, ensuring that the valve body 3 can be installed in a predetermined position and thus connected to the water pipe 2. A branch pipe 4 spans the inlet and outlet pipes. The branch pipe 4's spanning structure ensures pressure buffering against the reciprocating water hammer force inside the water pipe 2. A buffer assembly is slidably installed inside the branch pipe 4 to seal it. This buffer assembly buffers the pressure impact force inside the branch pipe 4, ensuring its buffering effect and thus the water pressure inside the water pipe 2. The buffer assembly is slidably connected to a sealing head 10 inside the branch pipe 4. The sealing head 10 seals the branch pipe 4 when the pressure in the water pipe 2 is below a predetermined value, ensuring the valve's sealing effect when the pressure fluctuation inside the water pipe 2 is small. A buffer element 7 is provided between the sealing head 10 and the branch pipe 4. The buffer element 7 buffers the impact force of the sealing head 10, ensuring that the pressure inside the water pipe 2 is buffered by the action of the sealing head 10 and the buffer element 7.

[0020] In one embodiment, in order to achieve buffering and control of the pressure inside the branch pipe 4, a sliding sleeve 5 is provided in the middle section of the branch pipe 4. The buffer assembly is slidably connected to the inside of the sliding sleeve 5. The diameter of the sliding sleeve 5 is larger than the diameter of the branch pipe 4, ensuring that the pressure inside the sliding sleeve 5 can be less than the pressure in the branch pipe 4, ensuring that the impact force on the plug head 10 and the buffer assembly can be reduced and buffered, and ensuring the buffering effect of the pressure inside the branch pipe 4.

[0021] Specifically, in combination Figure 4 To ensure a proper seal between the plug head 10 and the sliding sleeve 5, the sliding sleeve 5 has a sealing part 11 at one end of the inlet pipe. The front end of the plug head 10 has a sealing bevel 101 corresponding to the sealing part 11. By fitting the sealing part 11 and the sealing bevel 101 together, the water inside the branch pipe 4 can be blocked, ensuring the sealing effect of the entire valve body 3. The side wall of the plug head 10 has several evenly arranged permeable holes 102. The permeable holes 102 are located on the sealing bevel 101. When the plug head 10 slides backward under force, the permeable holes 102 connect the two sides of the plug head 10, ensuring that the position of the plug head 10 can be changed, thus achieving the bypass effect of the branch pipe 4.

[0022] In one embodiment, in order to ensure the buffering effect of the sealing head 10 under force, one end of the buffer member 7 abuts against the end of the sealing head 10 away from the water inlet pipe, and the other end of the buffer member 7 abuts against the inner wall of the sliding sleeve 5 to ensure the buffering effect of the buffer member 7. At the same time, the buffer member 7 can be an elastic member with a buffering effect, such as a damping spring, to ensure that the impact of the sealing head 10 under force can be buffered, thereby ensuring the buffering effect on the branch pipe 4.

[0023] Furthermore, in order to achieve further buffering while ensuring the continuity of branch pipe 4, a filter element is provided at the end of the sliding sleeve 5 away from the plugging head 10. A sliding tube 103 is provided on the plugging head 10 and sleeved on the filter element. The sliding tube 103 is slidably connected to the outside of the filter element. By adjusting the position of the sliding tube 103 and the filter element, the sliding effect of the plugging head 10 is ensured, while ensuring the continuity of branch pipe 4.

[0024] In one embodiment, the filter element is a filter cylinder 8, the sliding tube 103 is slidably disposed outside the filter cylinder 8, the filter cylinder 8 is provided with filter holes 9, the buffer 7 abuts between the sliding tube 103 and the sliding sleeve 5, the valve body 3 is provided with a valve core 6 inside, the two ends of the branch pipe 4 are provided on both sides of the valve body 3, and the top of the valve core 6 is provided with a control handle 1, so that the position of the valve core 6 can be controlled to achieve the opening and closing effect of the control valve.

[0025] When in use, first install the entire control valve onto the corresponding water pipe 2, then open the valve core 6. When there is a large pressure fluctuation inside the water pipe 2, the fluctuation is directly transmitted to the sealing head 10 through the branch pipe 4. The sealing head 10 and the buffer 7 are used for buffering, which ensures that the pressure inside the water pipe 2 can be effectively buffered, and at the same time reduces the maintenance cost of inflating the airbag later.

[0026] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
