Visual mechanical pressure valve for fire fighting

Abstract

According to the visual mechanical pressure valve for fire fighting provided by the embodiment of the invention, along with the continuous increase of the pressure of a fire fighting water system, a water source can impact the bottom surface of the valve cover and enable the first spring seat to drive the valve rod and the spiral spring to move upwards. In the process, the valve rod can move in the direction of the second spring seat and the valve cover, and meanwhile the spiral spring can be extruded. In the upward moving process of the valve element, a color card arranged on the outer wall of the valve element can be displayed outwards through an observation window of the valve deck. Due to the fact that the color cards with different colors are distributed in the vertical direction of the valve element, the color cards can display different colors outwards through the observation window along with continuous increase of water pressure, and the warning effect is achieved. By adopting the structural design, various different colors can be bound with the water pressure of the fire-fighting system, so that the water pressure condition of the fire-fighting water pressure system can be visually displayed by displaying the different colors outwards, and potential safety hazards can be avoided to a certain extent.

Description

Technical Field

[0001] This application relates to the field of fire-fighting equipment technology, and more specifically, to a direct-access mechanical pressure valve for fire-fighting. Background Technology

[0002] A fire-fighting pressure valve is a valve installed in a fire protection system to control the pressure at the water source outlet. It is a crucial component of the fire protection system, its main function being to prevent excessive pressure within the system and ensure the stability of the water source outlet to meet fire-fighting water requirements.

[0003] Under normal circumstances, fire pressure valves are usually installed in water supply boxes in fire-fighting toilets, corridors, etc., and the current pressure value is displayed through a pressure gauge or digital display screen.

[0004] However, since pressure gauges or digital displays require close-range readings to obtain information, staff cannot directly perceive whether the internal pressure of the fire protection system is too high or too low, which can easily lead to safety hazards over time. Utility Model Content

[0005] In view of this, embodiments of this application provide a visually intuitive mechanical pressure valve for fire fighting.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] A fire-fighting intuitive mechanical pressure valve includes:

[0008] The valve body has a water inlet on its bottom surface and a water outlet on its side surface. The axes between the water outlet and the water inlet are perpendicular to each other. The valve body also has a mounting hole at its top.

[0009] The valve core sleeve is slidably disposed in the valve body through the mounting hole. The outer surface of the side wall of the valve core is in contact with the inner surface of the side wall of the valve body. The outer surface of the side wall of the valve core is provided with a variety of color cards. The same type of color cards are distributed along the circumferential direction of the valve core, and the different types of color cards are distributed along the length direction of the valve core. The color cards are located near the bottom end of the valve core. The bottom surface of the valve core is used to seal the water inlet.

[0010] The valve cover is installed in the mounting hole of the valve body by means of a threaded connection. The valve cover has multiple observation windows circumferentially arranged on the side wall. The observation windows are located near the bottom of the valve cover and are used to display the colors in the color card.

[0011] A valve stem is disposed inside the valve core. A first spring seat is fixedly disposed at the bottom end of the valve stem and is fixedly connected to the valve core. A helical spring is disposed on the outer sleeve of the valve stem. A second spring seat is slidably connected to the top end of the valve stem and is fixedly connected to the valve cover. The two ends of the helical spring abut against the first spring seat and the second spring seat, respectively.

[0012] In some possible implementations, an annular baffle is provided around the mounting hole of the valve body, and the valve core is disposed within the annular baffle and slidably connected thereto.

[0013] In some possible implementations, the valve core is slidably connected to the valve cover via a limiting ring at its top. The limiting ring has a first water-permeable hole along its thickness direction, and the top of the valve cover has a second water-permeable hole. When the valve core is detached from the annular baffle, the water inlet, the first water-permeable hole, and the second water-permeable hole are connected.

[0014] In some possible implementations, the top surface of the valve cover is provided with a drain pipe that communicates with the second water-permeable hole.

[0015] In some possible implementations, a valve cap is also provided inside the valve cover, the valve cap is fixedly connected to the valve cover, the valve cap is slidably connected to the valve stem, and the bottom end of the valve cap is connected to the second spring seat.

[0016] In some possible implementations, a valve sleeve is also included, which is slidably disposed within the valve core and located outside the helical spring.

[0017] The intuitive mechanical pressure valve for fire fighting provided in this application has at least the following beneficial effects:

[0018] In the fire-fighting intuitive mechanical pressure valve provided in this embodiment, as the pressure of the fire-fighting water system increases, the water source impacts the bottom surface of the valve cover, causing the first spring seat to drive the valve stem and helical spring upwards. During this process, the valve stem moves towards the second spring seat and the valve cover, while also compressing the helical spring. As the valve core moves upwards, the color card on its outer wall is displayed through the observation window of the valve cover. Since different color cards are distributed along the vertical direction of the valve core, as the water pressure increases, the color cards will display different colors through the observation window, serving as a warning. By adopting the above structural design, multiple different colors can be linked to the fire-fighting system water pressure, allowing for a direct display of the fire-fighting water pressure system's status by showing different colors, thereby mitigating potential safety hazards to some extent.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-4 As shown in the embodiment of this application, the fire-fighting intuitive mechanical pressure valve includes a valve body 100, a valve core 200, a valve cover 400, and a valve stem 600. The bottom surface of the valve body 100 has a water inlet 110, and the side surface of the valve body 100 has a water outlet 120. The axes of the water inlet 110 and the water outlet 120 are perpendicular to each other. The top of the valve body 100 also has a mounting hole 130, through which other components of the pressure valve can be installed within the valve body 100.

[0028] The valve core 200 is slidably disposed inside the valve body 100 through the mounting hole 130. Specifically, the outer surface of the sidewall of the valve core 200 contacts the inner surface of the sidewall of the valve body 100, allowing the valve core 200 to move up and down within the valve body 100. The outer surface of the sidewall of the valve core 200 is also provided with color cards 300 of various colors. Multiple color cards 300 of the same color are circumferentially distributed on the outer surface of the sidewall of the valve core 200, while multiple color cards 300 of different colors are distributed axially on the outer surface of the sidewall of the valve core 200. Furthermore, all the color cards 300 are positioned at a lower position on the outer surface of the sidewall of the valve core 200.

[0029] In this embodiment, a valve cover 400 is threadedly connected to the mounting hole 130 of the valve body 100, and the valve cover 400 is used to seal the mounting hole 130. The side wall of the valve cover 400 is provided with a plurality of observation windows 500, and each observation window 500 is provided with a transparent structure, such as transparent glass, so that the color card 300 provided on the valve core 200 can be observed from the outside through the transparent structure of the observation window 500.

[0030] like Figure 2 and Figure 3 As shown, the valve stem 600 is disposed inside the valve core 200. A first spring seat 610 is fixedly disposed at the bottom end of the valve stem 600, and the valve stem 600 is fixedly connected to the valve core 200 through the first spring seat 610. The valve stem 600 can close the water inlet 110 of the valve body 100 by controlling the valve core 200. A second spring seat 620 is slidably disposed at the top end of the valve stem 600, and the second spring seat 620 is fixedly connected to the valve cover 400. Furthermore, a helical spring 700 is sleeved on the outside of the valve stem 600, and the two ends of the helical spring 700 abut against the first spring seat 610 and the second spring seat 620, respectively.

[0031] In the fire-fighting intuitive mechanical pressure valve provided in this embodiment, as the pressure of the fire-fighting water system continuously increases, the water source impacts the bottom surface of the valve cover 400, causing the first spring seat 610 to drive the valve stem 600 and the helical spring 700 upwards. During this process, the valve stem 600 moves towards the second spring seat 620 and the valve cover 400, while also compressing the helical spring 700. As the valve core 200 moves upwards, the color card 300 on its outer wall is displayed outwards through the observation window 500 of the valve cover 400. Since the color cards 300 of different colors are distributed along the vertical direction of the valve core 200, as the water pressure continuously increases, the color cards 300 will display different colors outwards through the observation window 500 to serve as a warning. By adopting the above structural design, multiple different colors can be bound together with the fire-fighting system water pressure, so as to intuitively display the water pressure status of the fire-fighting water system by displaying different colors outwards, thereby avoiding the occurrence of safety hazards to a certain extent.

[0032] In some embodiments, an annular baffle 131 is provided around the mounting hole 130 of the valve body 100, and the annular baffle 131 is in contact with the valve core 200. Preferably, a limiting ring 210 is provided at the top of the valve core 200, and the valve core 200 is slidably connected to the valve cover 400 through the limiting ring 210 at its top. The limiting ring 210 is also provided with a first water-permeable hole 220 along the thickness direction, and a second water-permeable hole 410 is provided at the top of the valve cover 400.

[0033] When the pressure of the fire-fighting water system continuously increases, the valve core 200 will compress the helical spring 700 and move upwards until the valve core 200 moves to its bottom end and disengages from the annular baffle 131. Then, the fire-fighting water can drain outwards through the gap between the valve core 200 and the limiting ring 210, sequentially through the first water-permeable hole 220 and the second water-permeable hole 410, thereby reducing the pressure at the outlet 120. Preferably, the top of the valve cover 400 is also provided with a drain pipe 420 connected to the second water-permeable hole 410.

[0034] In some embodiments, a valve cap 800 is further provided inside the valve cover 400. The valve cap 800 is fixedly connected to the valve cover 400, and the valve cap 800 is slidably connected to the valve stem 600. The valve cap 800 is fixedly connected to the second spring seat 620, and the valve stem 600 can pass through the second spring seat 620 and extend into the interior of the valve cap 800.

[0035] In some embodiments, a valve sleeve 900 is also provided inside the valve core 200. The valve sleeve 900 is sleeved on the outside of the helical spring 700 and the valve stem 600, thereby protecting the helical spring 700 and the valve stem 600 from water immersion and extending the service life of the valve stem 600 and the helical spring 700.

[0036] The various embodiments or implementation methods described in this specification are presented in a progressive manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts between the embodiments can be referred to each other.
