[0041] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0042] like Figures 1 to 6 As shown, the easily adjustable fire-fighting water distributor of this utility model includes:

[0043] Valve body 11 has an internal cavity;

[0044] The inlet pipe 12 is fixedly connected to and communicates with the valve body 11, and is used to receive fire water;

[0045] Diversion pipe 13 is fixedly connected to valve body 11 and interconnected with it. Diversion pipe 13 is provided with two sets of water outlets for diverting and discharging the fire water input from inlet pipe 12.

[0046] The cover bracket 14 is mounted on the top of the valve body 11;

[0047] The regulating mechanism 2 is installed on the valve body 11 and is used to control the opening and closing of the valve body 11 and prevent liquid backflow.

[0048] The regulating mechanism 2 also includes:

[0049] A sealing seat 21 is fixedly installed at the connection port between the valve body 11 and the water inlet pipe 12, and a water outlet is provided on the sealing seat 21.

[0050] The slide rod 22 is slidably inserted into the sealing seat 21;

[0051] One-way valve plate 23 is fixedly installed on slide bar 22, and one-way valve plate 23 is covered and installed on the top of sealing seat 21;

[0052] The water control plug 24 is vertically slidably disposed inside the valve body 11;

[0053] The sealing ring 25 is fixedly installed inside the valve body 11 and is located between the sealing seat 21 and the control plug 24.

[0054] The working process and principle of the device are as follows: The slide bar 22 in the adjusting mechanism can slide in the sealing seat 21, while the one-way valve plate 23 is fixedly installed on the slide bar; when fire water flows into the valve body 11 from the inlet pipe 12, the water pressure will push the one-way valve plate to open, allowing water to flow through; when the fire water pressure decreases or the water source is cut off, the one-way valve plate will close due to its own weight, thereby effectively preventing liquid backflow; this not only avoids the waste of water resources, but also protects the safety of the fire protection system; the control plug 24 slides vertically inside the valve body 11, and by changing its position, the size of the channel through which fire water enters the diversion pipe 13 can be controlled, thereby fine-tuning the flow rate; this design increases the flexibility of adjustment, enabling the fire water distributor to adapt to the fire extinguishing needs in different scenarios.

[0055] like Figure 3 As shown, the sealing seat 21 is set in a conical shape; when fire water flows in from the inlet pipe 12, the water pressure pushes the one-way valve plate 23 to open, allowing the water to flow through the water outlet on the sealing seat 21 into the cavity of the valve body 11; the conical sealing seat design allows the water flow to gradually diffuse as it passes through, reducing the direct impact of the water flow on the sealing seat, which helps to maintain the stability and sealing effect of the sealing seat.

[0056] like Figure 2 As shown, the adjustment mechanism 2 also includes:

[0057] Two support pillars 26 are symmetrically fixedly installed on the cover bracket 14;

[0058] Adjusting plate 27, fixedly connected to two adjusting plates 27, with a threaded hole in the middle of the adjusting plate 27;

[0059] Screw 28 is inserted into the threaded hole of adjusting plate 27;

[0060] The linkage slide rod 29 is vertically slidably inserted into the cover bracket 14, and its height is adjusted by the screw 28. The bottom end of the linkage slide rod 29 is fixedly connected to the water control plug 24.

[0061] The working process and principle of the regulating mechanism 2 are as follows: When it is necessary to regulate the flow rate of fire water, the operator can rotate the screw 28; since the screw 28 is engaged with the threaded hole of the regulating plate 27, rotating the screw will cause it to move up and down along the threaded hole; the up and down movement of the screw 28 drives the linkage slide rod 29 to slide vertically in the cover bracket 14; the sliding of the linkage slide rod 29 further drives the water control plug 24 to move up and down inside the valve body 11; the change in the position of the water control plug 24 will change the size of the channel through which fire water enters the diversion pipe 13, thereby realizing the regulation of the flow rate; by continuously rotating the screw 28 and observing the change in flow rate, the operator can accurately adjust the water control plug 24 to the required position to achieve the required flow rate; once the water control plug 24 is adjusted to the appropriate position, the fire water will be discharged through the diversion pipe 13 according to the predetermined flow rate to meet the fire extinguishing needs; the rapid and accurate regulation of the fire water flow rate is realized, the regulating performance of the fire water distributor is improved, and its reliability and service life are also enhanced.

[0062] The regulating mechanism 2 also includes:

[0063] Handwheel 2a is fixedly mounted on the top of screw 28; handwheel 2a and screw 28 are fixedly mounted together to form an integral structure; when the handwheel rotates, it will drive the screw to rotate and move up and down together; the rotation of handwheel 2a provides the operator with an intuitive and convenient way to control the position and flow of the water control plug, improving the ease of use.

[0064] For example, 5 to Figure 6 As shown, the adjustment mechanism 2 also includes:

[0065] The guide post 2b is located at the bottom of the water control plug 24 and is used to limit the sliding stroke of the slide rod 22;

[0066] The elastic spring 2c is fixedly installed on the top of the one-way valve plate 23 and fitted onto the guide post 2b. The top of the elastic spring 2c is in contact with the bottom of the water control plug 24.

[0067] When the fire water pressure decreases or the water supply is cut off, the one-way valve plate 23 will be tightly pressed against the top of the sealing seat 21 by the elastic force of the spring 2c, thereby preventing liquid backflow. The design of the one-way valve plate allows water to flow only from the inlet pipe 12 to the branch pipe 13, and not in the reverse direction. The combination of the guide post 2b and the spring 2c further enhances this backflow prevention function, because even in the event of water pressure fluctuations or sudden drops, the spring can quickly push the one-way valve plate back to the sealing position. This not only improves the regulating performance and stability of the fire water distributor, but also enhances its backflow prevention function, making the entire fire protection system safer and more reliable.

[0068] The bottom of the guide post 2b is equipped with an anti-collision pad; the anti-collision pad is made of elastic material and has good elasticity and resilience; when the inlet water pressure is high, the one-way valve plate 23 will rise to its highest point, and the top of the one-way valve plate 23 will collide with the bottom of the guide post 2b. In other words, the guide post 2b will limit the one-way valve plate 23. The anti-collision pad can buffer the impact between the guide post 2b and the one-way valve plate 23, prevent component damage, and improve service life.

[0069] like Figure 2 As shown, a drain plug 121 is threadedly inserted into the bottom of the inlet pipe 12. When maintenance or cleaning of the fire water distributor is required, the drain plug 121 can be rotated counterclockwise to unscrew it from the bottom of the inlet pipe 12. After unscrewing the drain plug 121, the accumulated water or impurities inside the inlet pipe 12 and valve body 11 can be easily drained, facilitating subsequent maintenance or cleaning. After maintenance or cleaning is completed, the drain plug 121 can be rotated clockwise again to tighten it, restoring its sealing function and improving its usability.

[0070] The top of the cover bracket 14 is fitted with a sealing cover 141, and the linkage slide rod 29 is slidably disposed in the sealing cover 141. The presence of the sealing cover 141 not only provides a sliding channel for the linkage slide rod 29, but also plays an additional sealing role. When the fire water distributor is in a non-working state or after adjustment, the sealing cover 141 can prevent external impurities, dust or moisture from entering the valve body 11, thereby ensuring the cleanliness and service life of the fire water distributor.

[0071] The fire-fighting water distributor of this utility model can be installed, connected, or set up in a common mechanical manner, and can be implemented as long as it can achieve its beneficial effect.

[0072] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
