Description

Technical Field

[0001] This utility model relates to the field of valve technology, and more specifically, to a novel integrated breathing emergency relief valve. Background Technology

[0002] Most of the conventional structures of breathing integrated emergency relief valves on the market today are coaxial, as disclosed in Chinese patent document CN219317726U. In this structure, the exhalation valve disc assembly and the inhalation valve disc assembly are on the same axis, the inhalation structure is set on the exhalation valve disc, the area of ​​the inhalation port is much smaller than the relief area of ​​the relief valve, and the inhalation sealing diaphragm and the inhalation valve disc are set below the inhalation valve seat. The inhalation structure is a structure in which the valve disc opens downward.

[0003] Existing integrated breathing emergency relief valves have the following drawbacks: Firstly, when the tank pressure is lower than the set inhalation pressure, the inhalation valve disc assembly opens downwards to draw in air and maintain stable tank pressure. At this time, the medium inside the tank is easily adsorbed on the top of the inhalation valve disc assembly. At the same time, after closing, external dust is easily accumulated on the inhalation valve disc assembly, which not only affects opening but also affects sealing. Secondly, because the inhalation structure is set on the exhalation valve disc, the inhalation port area is much smaller than the relief area of ​​the relief valve, affecting the pressure replenishment efficiency. Moreover, this structure requires the exhalation valve disc assembly and the inhalation valve disc assembly to be assembled as a single unit, which is difficult to assemble. When the inhalation valve disc assembly is damaged and needs repair, the exhalation valve disc assembly must also be removed, which is inconvenient for repair. Utility Model Content

[0004] To address the aforementioned problems, this utility model discloses a novel integrated breathing emergency relief valve, which solves the issues of dust accumulation, inconvenient maintenance, and insufficient ventilation capacity in existing conventional structures. It includes: The valve body assembly includes an exhalation valve seat and an inhalation valve seat, with the inhalation valve seats arranged side by side at the side end of the exhalation valve seat. The exhalation valve disc assembly is placed above the exhalation valve seat; The intake valve disc assembly is placed above the intake valve seat.

[0005] Preferred options also include: Side connecting plate, the side connecting plate is set at a right angle, and the side connecting plate is installed on the side end of the valve body assembly; The support assembly is rotatably mounted on the side connecting plate via a pin, and the top of the exhalation valve disc assembly is hinged to the bottom of the support assembly.

[0006] Preferably, the support assembly is equipped with an exhalation weight.

[0007] Preferably, it further includes: a valve cover, an inhalation chamber and an exhalation chamber arranged side by side within the valve body assembly, the valve cover being installed at the top of the inhalation chamber, an inhalation valve disc assembly being placed at the bottom of the inhalation chamber, the inhalation valve disc assembly being composed of a first nut, an inhalation clamping plate, an inhalation support pad, an inhalation sealing membrane, an inhalation valve disc, an inhalation counterweight, a locking retaining ring, and an inhalation valve rod, the top end of the inhalation valve rod penetrating into the inner hole of the valve cover guide sleeve, the valve cover guide sleeve being vertically positioned at the center of the valve cover for vertical lifting and lowering of the inhalation valve rod; the inhalation valve disc being located at the lower end of the inhalation valve rod; and the inhalation sealing membrane being installed at the bottom end of the inhalation valve disc.

[0008] Preferably, an intake counterweight is installed at the top of the intake valve disc via a locking retaining ring.

[0009] Preferably, an air suction support pad is installed between the air suction clamping plate and the air suction sealing film.

[0010] Preferably, the valve cover is mounted to the top of the intake chamber by fasteners.

[0011] Preferably, the fastener is a fixing bolt.

The intake valve disc assembly is vertically sealed on the intake valve seat. The intake sealing membrane and the intake valve disc are located above the intake valve seat. The intake end adopts a structure where the valve disc opens upward. When the intake valve disc assembly opens upward, the medium in the storage tank will not be adsorbed on the intake sealing membrane. At the same time, after closing, external dust will not accumulate on the intake sealing membrane, thus avoiding affecting the normal opening and sealing effect of the intake valve disc assembly.

[0015] This utility model provides a novel integrated breathing emergency relief valve with inhalation and exhalation structures arranged side by side.

[0020] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example: The present invention will now be further described with reference to the accompanying drawings.

[0022] like Figures 1 to 4 As shown, this embodiment provides a novel integrated breathing emergency relief valve, comprising: Valve body assembly 1, which includes an exhalation valve seat 2 and an inhalation valve seat 12, with the inhalation valve seat 12 arranged side by side at the end of the exhalation valve seat 2; The exhalation valve disc assembly 4 is placed above the exhalation valve seat 2; The intake valve disc assembly 11 is placed above the intake valve seat 12.

[0023] The working principle and beneficial effects of the above technical solution are as follows: This utility model discloses a novel integrated breathing emergency relief valve. When the pressure inside the storage tank rises and exceeds the exhalation set pressure of the integrated breathing emergency relief valve, the exhalation valve disc assembly 4 is pushed up by the pressure inside the storage tank, releasing pressure outwards. When the pressure inside the storage tank drops and falls below the inhalation set pressure of the integrated breathing emergency relief valve, the inhalation valve disc assembly 11 opens upwards to replenish pressure. The inhalation valve disc assembly 11 is vertically sealed on the inhalation valve seat 12. The novel integrated breathing emergency relief valve provided by this utility model features an upward-opening structure for the inhalation valve disc assembly 11. When the inhalation valve disc assembly 11 opens upwards, the medium inside the storage tank will not be adsorbed onto the inhalation sealing membrane. Simultaneously, after closing, external dust will not accumulate on the inhalation sealing membrane, avoiding affecting the normal opening and sealing effect of the inhalation valve disc assembly 11. Furthermore, the exhalation valve disc assembly 4 and the inhalation valve disc assembly 11 are arranged side-by-side, improving overall ventilation efficiency and facilitating individual maintenance.

[0024] In one embodiment, it also includes: Side connecting plate 3, which is set at a right angle, is installed on the side end of valve body assembly 1; The bracket assembly 5 is rotatably mounted on the side connecting plate 3 via a pin 6 or a cotter pin, and the top of the exhalation valve disc assembly 4 is hinged to the bottom of the bracket assembly 5.

[0025] The working principle and beneficial effects of the above technical solution are as follows: like Figure 8 As shown, when the pressure inside the tank increases, the exhalation valve disc assembly 4 rotates and opens under the cooperation of the bracket assembly 5 and the pin 6, releasing the pressure outward. This structure makes the exhalation valve disc assembly 4 independent of the inhalation structure, simplifying assembly and avoiding the difficulty of assembling the exhalation valve disc assembly and inhalation valve disc assembly as a single unit in conventional structures, thus improving maintenance convenience.

[0026] In one embodiment, an exhalation weight 7 is mounted on the support assembly 5.

[0027] The working principle and beneficial effects of the above technical solution are as follows: The exhalation counterweight 7 is used to adjust the opening pressure of the exhalation valve disc assembly 4, ensuring stable opening and closing under the set pressure, thus improving the accuracy and reliability of pressure relief.

[0028] In one embodiment, a flange is installed at the bottom of the exhalation valve seat 2.

[0029] The beneficial effects of the above technical solution are as follows: The flange design facilitates the connection of the integrated breathing emergency relief valve to the storage tank, ensuring a secure connection and improving the convenience and safety of installation.

[0030] In one embodiment, the system further includes: a valve cover 8; an inhalation chamber 29 and an exhalation chamber 30 are arranged side by side within the valve body assembly 1; the valve cover 8 is installed at the top of the inhalation chamber 29; an inhalation valve disc assembly 11 is placed at the bottom of the inhalation chamber 29; the inhalation valve disc assembly 11 consists of a first nut 21, an inhalation clamping plate 22, an inhalation support pad 23, an inhalation sealing membrane 24, an inhalation valve disc 25, an inhalation counterweight 26, a locking retaining ring 27, and an inhalation valve rod 28; the top of the inhalation valve rod 28 passes through the inner hole of the valve cover guide sleeve 10; the valve cover guide sleeve 10 is vertically arranged at the center of the valve cover 8 to allow the inhalation valve rod 28 to move vertically up and down; the inhalation valve disc 25 is located at the lower end of the inhalation valve rod 28; and the inhalation sealing membrane 24 is installed at the bottom end of the inhalation valve disc 25.

[0031] The working principle and beneficial effects of the above technical solution are as follows: like Figure 9 As shown, when the tank pressure is lower than the set value, the suction valve disc assembly 11 opens upward along the valve cover guide sleeve 10 to draw in air and replenish the pressure. This structure, which adopts an upward-opening valve disc, avoids media condensation and dust accumulation on the suction sealing membrane 24, improving sealing stability and opening reliability. At the same time, the detachable design of the valve cover 8 facilitates maintenance.

[0032] In one embodiment, an intake counterweight 26 is mounted on the top of the intake valve disc 25 via a locking retaining ring 27.

[0033] The working principle and beneficial effects of the above technical solution are as follows: The intake counterweight 26 is fixed by the locking retaining ring 27 and is used to adjust the opening pressure of the intake valve disc assembly 11 to ensure stable opening and closing under the set pressure, thereby improving the accuracy and reliability of pressure compensation.

[0034] In one embodiment, an air suction support pad 23 is installed between the air suction clamping plate 22 and the air suction sealing film 24.

[0035] The beneficial effects of the above technical solution are as follows: The suction support pad 23 provides additional support and protection to prevent the suction sealing membrane 24 from deforming, ensuring that the sealing membrane remains intact under high pressure differential, thereby improving the durability and stability of the seal.

[0036] In one embodiment, the valve cover 8 is mounted on the top of the intake chamber by a fastener, which is a fixing bolt 9.

[0037] The working principle and beneficial effects of the above technical solution are as follows: Fasteners ensure that the valve cover 8 is firmly fixed, facilitating disassembly and assembly, improving maintenance efficiency, and avoiding the hassle of overall disassembly in conventional structures.

[0038] like Figure 5 and Figure 6As shown, in other embodiments of this application, the fastener includes: Side support plate 19, multiple side support plates 19 are circumferentially distributed on the side end of the air intake chamber near the top position; The union bolt 17 is rotatably mounted on the side support plate 19; The second nut 15 is screwed onto the union bolt 17.

[0039] The working principle and beneficial effects of the above technical solution are as follows: By engaging the union bolt 17 and the second nut 15, the valve cover 8 is locked to the top of the intake chamber, facilitating quick disassembly and replacement of the intake valve disc assembly 11, thus improving maintenance convenience, especially suitable for scenarios requiring frequent maintenance.

[0040] like Figure 7 As shown, in one embodiment, a filter screen 13 is installed at the bottom end of the intake valve seat 12, and a filter screen blowing port 20 is provided at the side end of the intake valve seat 12 near the bottom end.

[0041] The working principle and beneficial effects of the above technical solution are as follows: The filter screen 13 prevents garbage and impurities from entering the storage tank, and the filter screen blowing interface 20 facilitates the cleaning of accumulated impurities, ensuring unobstructed air intake and improving the reliability and service life of the device.

[0042] In one embodiment, the suction valve seat 12 is symmetrically equipped with lifting lugs 14 on its side end.

[0043] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
