Description

Technical Field

[0001] This utility model relates to the technical field of fire pump couplings, and in particular to a fire pump coupling. Background Technology

[0002] Fire pump connections are indispensable key components in fire protection systems, primarily used to connect external fire water sources and fire pipe networks. In emergencies such as fires, they replenish water supply and pressure to the fire protection system, ensuring the smooth operation of firefighting efforts. Currently, existing fire pump connections have numerous structural design shortcomings, failing to meet practical needs. Firstly, the outlet pipe sealing structure of most fire pump connections is poorly designed, often requiring an additional sealing cap for dust prevention. If the sealing cap is lost, dust cannot effectively prevent entry into the equipment, easily causing pipe blockage, internal component wear and corrosion, thus affecting the normal operation and service life of the equipment. Secondly, during operation, the pressure impact generated by the flow of the medium within the pipe directly affects various components of the existing fire pump connections, easily leading to component damage and operational instability. Therefore, we propose a new type of fire pump connection. Utility Model Content

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1, as Figure 1 - Figure 4 As shown, a fire pump connector includes a pipe body 1. A buffer mechanism 2 is provided on the outer surface of the pipe body 1. The buffer mechanism 2 includes a buffer pipe 201. A positioning pipe 202 is connected to the upper surface of the buffer pipe 201. A lifting plate 203 is slidably connected to the inner surface of the positioning pipe 202. A limit post 204 is fixedly connected to the upper surface of the lifting plate 203. A water outlet pipe 205 is connected to the outer surface of the positioning pipe 202. A positioning plug 206 is slidably connected to the inner surface of the water outlet pipe 205. A support frame 207 is fixedly connected to the inner surface of the water outlet pipe 205. Two first springs 208 are fixedly connected to the outer surface of the support frame 207. Push rods 209 are fixedly connected to the outer surfaces of the two first springs 208. The two push rods 209 are fixedly connected to the positioning plugs 206.

[0022] The effect achieved by the entire embodiment 1 is that the lifting plate 203 slides upward, and at the same time, the medium pressure in the positioning tube 202 acts on the positioning plug 206, overcoming the elastic force of the first spring 208 and pushing the positioning plug 206 to move. The positioning plug 206 drives the push rod 209 to slide along the connecting tube 3 and stretch the first spring 208, pushing the positioning plug 206 out of the water outlet pipe 205. The water outlet pipe 205 connected to the outer surface of the positioning tube 202 is used for drainage. The positioning plug 206 slidably connected to the inner surface of the water outlet pipe 205 is used to control the opening and closing of the water outlet pipe 205. The support frame 207 fixedly connected to the inner surface of the water outlet pipe 205 provides fixed support for the first spring 208.

[0023] Example 2, as Figure 1 - Figure 4As shown, two connecting pipes 3 are fixedly connected to the outer surface of the support frame 207, and two push rods 209 are slidably connected to the connecting pipes 3. A limit pipe 9 is provided on the upper surface of the positioning pipe 202. A second spring 4 is fixedly connected to the upper surface of the limit post 204. The other end of the second spring 4 is fixedly connected to the limit pipe 9. An installation frame 5 is fixedly connected to the inner surface of the buffer pipe 201. Multiple limit rods 6 are fixedly connected between the installation frame 5 and the limit pipe 9. The multiple limit rods 6 are slidably connected to the limit post 204 and the lifting plate 203. A check valve 7 is provided on the outer surface of the pipe body 1. An installation pipe 8 is provided on the other end of the check valve 7. The limit post 204 is slidably connected to the limit pipe 9. The buffer pipe 201 is connected to the pipe body 1.

[0024] The overall effect of embodiment 2 is that the limiting post 204 fixedly connected to the upper surface of the lifting plate 203 can slide synchronously with the lifting plate 203, the limiting tube 9 connected to the upper surface of the positioning tube 202 provides sliding guidance for the limiting post 204, the second spring 4 fixedly connected to the upper surface of the limiting post 204 can play an elastic reset role for the limiting post 204 and the lifting plate 203, the mounting bracket 5 fixedly connected to the inner surface of the buffer tube 201 is fixedly connected to the limiting tube 9 with multiple limiting rods 6 to ensure the stability of the lifting plate 203 and the limiting post 204 when sliding, the two connecting tubes 3 fixedly connected to the outer surface of the support frame 207 are slidably connected to the corresponding push rod 209 to provide guidance for the extension and retraction of the push rod 209, the check valve 7 connected to the outer surface of the tube body 1 can prevent the backflow of the medium in the tube body 1, and the mounting tube 8 connected to the other end of the check valve 7 is used to connect to the external pipeline.

[0025] Working principle: The outlet pipe 205 connected to the outer surface of the positioning pipe 202 is used for drainage. The check valve 7 connected to the outer surface of the pipe body 1 prevents the backflow of the medium in the pipe body 1. The installation pipe 8 connected to the other end of the check valve 7 is used for connection with external pipelines. In the non-working state, the first spring 208, with its elastic force or in a naturally extended state, presses the positioning plug 206 tightly against the inner wall of the outlet pipe 205 through the push rod 209, thereby sealing the outlet pipe 205 and preventing dust from entering and causing blockage or damage to components. When the fire pump connection is working, abnormal high pressure occurs inside the pipe body. The medium in the pipe body 1 enters the positioning pipe 202 through the connected buffer pipe 201, pushing the lifting plate 203 to slide upward. The lifting plate 203 drives the limiting post 204 to slide upward along the limiting pipe 9 and the limiting rod 6 and compress it. The second spring 4, along with the medium in the positioning tube 202 entering the outlet pipe 205, exerts pressure on the positioning plug 206. This pressure must overcome the elastic force of the first spring 208 to move the positioning plug 206. The positioning plug 206 drives the push rod 209 to slide along the connecting pipe 3 and compress the first spring 208, pushing the positioning plug 206 inward from the outlet pipe 205. At this time, the medium in the positioning tube 202 is discharged through the outlet pipe 205, completing the drainage operation. After the operation is completed, the second spring 4 and the first spring 208 reset, driving the lifting plate 203, the limiting post 204, and the positioning plug 206 back to their initial positions, thus achieving the sealing and dust prevention of the outlet pipe 205 again. In the actual pressure relief process, when abnormally high pressure occurs inside the pipe body 1, the medium pressure will act synchronously and evenly on the lifting plate 203. The positioning plug 206 ensures that the medium pressure can simultaneously drive the lifting plate 203 to slide smoothly upwards and the positioning plug 206 to open synchronously. This prevents the lifting plate 203 from being blocked by high pressure and unable to rise, or the positioning plug 206 from being blocked by insufficient pressure. This ensures that the entire pressure relief process is stable and efficient, and that the internal pressure of the pipe can be quickly and smoothly released.
