Description
Technical Field
[0001] The utility model relates to the technical field of fire hydrant equipment, in particular to a novel constant-pressure and pressure-reducing indoor fire hydrant. Background Technique
[0002] An indoor fire hydrant is a facility for supplying water from the indoor pipe network to the fire site. It is a fire-fighting water supply equipment for factories, warehouses, high-rise buildings, public places, ships, etc. It is usually installed in a fire hydrant box and used in combination with fire hoses, water guns and other equipment. When there is a fire alarm, quickly open the fire hydrant box, take out the hose and water gun, connect one end of the hose to the fire interface of the fire hydrant, connect the other end to the water gun, and then turn the fire hydrant handwheel counterclockwise to open it, and water can be sprayed to extinguish the fire. The fire hydrant is also called a fire plug. According to different use places, it can be divided into indoor fire hydrants and outdoor fire hydrants; the current rotary pressure-reducing fire hydrant generally 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 current indoor fire hydrant has poor pressure-reducing effect during use. Usually, the fire hydrant cannot adjust the diameter of the orifice plate to adjust the water pressure, so that the pressure-reducing effect is not obvious and it is not conducive to people's use. Therefore, we propose a novel constant-pressure and pressure-reducing indoor fire hydrant. Content of the Utility Model

A first water outlet and a second water outlet communicating with the flow channel are opened inside the fire hydrant valve body. An annular sleeve is arranged inside the first water outlet, a rotating plate is clamped inside the annular sleeve, and an operating shaft is connected to the top of the rotating plate. Arc-shaped channels that can communicate are opened on the annular sleeve and the rotating plate.
[0005] In the above solution, a connecting pipe is connected to the water inlet, and the connection part between the two is sealed by a sealing ring.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: This new type of pressure-stabilizing and pressure-reducing indoor fire hydrant has a simple and reasonable structural design and strong practicability. By arranging two groups of valve mechanisms composed of a first valve plate and a second valve plate in the flow channel of the fire hydrant body, the flow channel of water can be automatically switched, so as to meet the connection effects at different interfaces and expand the application range of the equipment. By arranging a pressure-reducing and regulating mechanism composed of an annular sleeve and a rotating plate in the first water outlet, the rotating plate rotates by rotating the operating shaft, so that the rotating plate coincides with two arc-shaped channels on the annular sleeve, thereby forming an outlet channel for water flow. The size of the outlet can be adjusted according to the situation to meet the use requirements, achieving the advantage of good pressure-reducing effect, and solving the problem that the existing indoor fire hydrants have poor pressure-reducing effect when in use.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0016] Please refer to Figure 1-2, the present utility model provides a technical solution: a new type of voltage-stabilizing and pressure-reducing indoor fire hydrant, including a fire hydrant valve body 1. Both ends of the fire hydrant valve body 1 are provided with a water inlet 11 and a first connection port 12. The bottom of the fire hydrant valve body 1 is provided with a second connection port 25. A flow channel 13 is provided inside the fire hydrant valve body 1. Two sets of valve mechanisms are arranged inside the flow channel 13. The valve mechanism includes a first valve plate 16 and a second valve plate 17, and a rotating shaft 18 is connected to the tops of the first valve plate 16 and the second valve plate 17. A first water outlet 2 and a second water outlet 26 communicating with the flow channel 13 are provided inside the fire hydrant valve body 1. An annular sleeve 21 is arranged inside the first water outlet 2. A rotating plate 22 is clamped inside the annular sleeve 21, and an operating shaft 24 is connected to the top of the rotating plate 22. Arc-shaped channels 23 that can communicate are provided on the annular sleeve 21 and the rotating plate 22.
[0017] By arranging a pressure-reducing and regulating mechanism composed of an annular sleeve 21 and a rotating plate 22 inside the first water outlet 2, the rotating plate 22 rotates by driving the operating shaft 24, so that the two arc-shaped channels 23 on the rotating plate 22 and the annular sleeve 21 overlap, thereby forming an outlet channel for water flow. The size of the outlet can be adjusted according to the situation to meet the use requirements, achieving the advantage of good pressure-reducing effect, and solving the problem that the existing indoor fire hydrants have poor pressure-reducing effect when in use. Usually, the diameter of the orifice plate of the fire hydrant cannot be adjusted, so that the pressure-reducing effect is not obvious, and thus it is not convenient for people to use.
[0018] When the first valve plate 16 and the second valve plate 17 are opened, the first water outlet 2 is closed at this time, and the water flow flows horizontally through the flow channel and then flows out from the first connection port 12. At this time, the condition of full-power water delivery is met. When the first valve plate 16 is opened and the second valve plate 17 is closed, the arc-shaped channel 23 on the rotating plate 22 and the arc-shaped channel 23 on the annular sleeve 21 are gradually overlapped by rotating the operating shaft 25. The requirement of pressure-reducing adjustment is realized by adjusting the contact area between the two. At this time, the water flow flows out from the second connection port 25 after passing through the first water outlet 2.
[0019] In the above solution, a connecting pipe 14 is connected to the water inlet 11, and the connection between the two is sealed by a sealing ring 15.
[0020] In the above solution, a protective cover 19 is sleeved on the top of the fire hydrant valve body 1. The design of the protective cover 19 can protect the internal mechanism and avoid misoperation. The protective cover 19 can be removed during work to adjust the internal mechanism of the fire hydrant valve body 1.
[0021] In the above solution, the rotating shaft 18 is rotatably connected to the fire hydrant body 1, and a knob is provided at the top of the rotating shaft 18. By providing two valve mechanisms composed of a first valve plate 16 and a second valve plate 17 in the flow channel 13 of the fire hydrant body 1, the flow passage of the water can be automatically switched, so as to meet the connection effects at different interfaces and expand the applicable range of the equipment. Specifically, the first valve plate 16 and the second valve plate 17 can rotate in the corresponding limiting grooves, and sealing rings are provided on the outer rings of both of them as waterproof mechanisms.
[0022] In the above solution, the operating shaft 24 is rotatably connected to the fire hydrant body 1 through a bearing.
[0023] In the above solution, the first connection port 12 is connected to the water outlet pipe.
[0024] In the above solution, a sealing sleeve is sleeved on the outer edge of the rotating plate 22.
[0025] Working principle:
[0026] For this new type of indoor fire hydrant with stable pressure and pressure reduction, by providing a pressure reduction and adjustment mechanism composed of an annular sleeve 21 and a rotating plate 22 in the first water outlet 2, the rotating plate 22 is rotated by rotating the operating shaft 24, so that the two arc-shaped channels 23 on the rotating plate 22 and the annular sleeve 21 overlap, thus forming an outlet channel for water flow. The size of the outlet can be adjusted according to the situation to meet the use requirements, achieving the advantage of good pressure reduction effect and solving the problem of poor pressure reduction effect of the existing indoor fire hydrants during use. When the first valve plate 16 and the second valve plate 17 are opened, the first water outlet 2 is closed at this time, and the water flows horizontally through the flow channel and then flows out from the first connection port 12. At this time, the condition of full-power water delivery is met. When the first valve plate 16 is opened and the second valve plate 17 is closed, the arc-shaped channel 23 on the rotating plate 22 and the arc-shaped channel 23 on the annular sleeve 21 are gradually overlapped by rotating the operating shaft 25, and the requirement of pressure reduction adjustment is realized by adjusting the contact area between the two. At this time, the water flows through the first water outlet 2 and then flows out from the second connection port 25.
