Description

Technical Field

[0001] The utility model relates to the technical field of fire hydrant equipment, and specifically relates to a rotary pressure-reducing indoor fire hydrant. Background Technique

[0002] A fire hydrant is also called a fire plug, and can be divided into an indoor fire hydrant and an outdoor fire hydrant according to different usage places; the current rotary pressure-reducing fire hydrant reduces the pressure of water through a pressure-reducing orifice plate to prevent excessive water pressure and meet the requirements of the outlet pressure and flow rate of the fire hydrant. However, the existing rotary pressure-reducing fire hydrant cannot adjust the pressure, and the water pressure is different on different floors, resulting in an unobvious pressure-reducing effect, which is not conducive to people's use. In addition, the existing fire hydrant valve body is generally restricted by the structure and is inconvenient to install a filtering mechanism, and impurities may enter the valve body along with the water flow, which has certain drawbacks. Therefore, we propose a rotary pressure-reducing indoor fire hydrant. Content of the Utility Model

[0018] In the above solution, a water inlet 18 is opened above the filter element 17. The water inlet end of the fire hydrant valve body 1 is communicated with a water inlet pipe. After the water flow enters the interior of the flow channel 13 of the fire hydrant valve body 1 through the inlet, it is discharged from the pressure-reducing port 19 and the water outlet 2 after being filtered by the filter element 17.

[0019] In the above solution, a protective cover 26 is sleeved on the limit seat 25. The protective cover 26 is installed on the limit seat 25 in a detachable connection manner. After the protective cover 26 is removed, the rotary rod 24 can be manually rotated and adjusted, so as to adjust the height of the adjustment block 21. The side of the adjustment block 21 can block the pressure-reducing port 19.

[0020] In the above solution, an access opening is opened on the side of the fire hydrant valve body 1, and a baffle plate 28 is installed in the access opening through a screw 27.

The adjusting block 21 is used to partially block the pressure relief port 19, so as to control the flow rate and pressure of the water flow, solving the problem that the existing rotating pressure relief indoor fire hydrant has no pressure adjustment function. This rotating pressure relief indoor fire hydrant has the advantage of having a pressure adjustment function.

[0024] Working principle:

[0025] For this kind of rotating pressure relief indoor fire hydrant, by installing a filter element 17 inside the fire hydrant valve body 1, impurities in the liquid can be filtered, thus avoiding blockage problems after long-term use of the equipment. The effect of integrating the filtering mechanism on the main pressure reducing valve mechanism can be achieved, with a compact volume and less occupied space, effectively improving the use effect of the pressure reducing valve mechanism and solving the problem that ordinary fire hydrant valve bodies do not have a filter mechanism. The water inlet end of the fire hydrant valve body 1 is connected to the water inlet pipe. After the water flow enters the flow channel 13 of the fire hydrant valve body 1 through the inlet and is filtered by the filter element 17, it is discharged from the pressure relief port 19 and the water outlet 2. When the water pressure needs to be adjusted, the protective cover 26 can be removed and the rotating rod 24 can be manually rotated to adjust the height of the adjusting block 21. The side of the adjusting block 21 can block the pressure relief port 19, so as to control the flow rate and pressure of the water flow, solving the problem that the existing rotating pressure relief indoor fire hydrant has no pressure adjustment function, making this rotating pressure relief indoor fire hydrant have the advantage of having a pressure adjustment function.
