[0001] This application relates to the field of fire protection maintenance technology, and more specifically, to a pressure-pressurizing device. Background Technology

[0002] During fire protection maintenance, it is necessary to pressure test the closed-type fire sprinklers. The existing method for pressure testing closed-type sprinklers is to fix each sprinkler individually on a pressure testing platform and pressure test them one by one. This method has low pressure testing efficiency, resulting in low fire protection maintenance efficiency.

[0003] In conclusion, how to improve the pressure-pressurization efficiency of closed sprinkler heads to enhance the efficiency of fire protection maintenance is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a pressure-pressurizing device to improve the pressure-pressurizing efficiency of closed sprinkler heads, thereby improving the efficiency of fire protection maintenance.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A pressure testing device includes a tapping component; wherein the tapping component includes: a communicating cavity, a connecting hole, and at least two interfaces, the interfaces being used to connect a closed nozzle, the connecting hole being used to connect a pressure testing platform, and the communicating cavity communicating with the connecting hole and each of the interfaces.

[0007] In some embodiments, the interface is formed on the circumferential sidewall of the tapping component;

[0008] Along the axial direction of the tap member, the interface is at least two; and / or, along the circumferential direction of the tap member, the interface is at least two.

[0009] In some embodiments, the tapping component is a regular prism, and each side of the regular prism is provided with at least one of the interfaces.

[0010] In some embodiments, the interface is a threaded hole; and / or, a seal is fixedly connected to the inner wall of the interface.

Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0027] like Figures 1-2As shown, the pressure testing device provided in this embodiment includes a tapping component 3, which includes a connecting cavity, a connecting hole, and at least two interfaces 4. The interfaces 4 are used to connect closed sprinkler heads. Since one interface 4 connects to one closed sprinkler head, the tapping component 3 can connect at least two closed sprinkler heads simultaneously. The connecting hole of the tapping component 3 is used to connect to the pressure testing platform. The connecting cavity can connect the connecting hole and each interface 4. In this way, the pressurized gas from the pressure testing platform can enter the tapping component 3 through the connecting hole and then be delivered to each interface 4 through the connecting cavity, thereby simultaneously pressurizing the closed sprinkler heads connected to each interface 4, improving the pressure testing efficiency of the closed sprinkler heads and improving the efficiency of fire protection maintenance.

[0028] In practice, since different types of closed nozzles require different pressures, the pressure-pressuring device provided in this application embodiment pressurizes multiple closed nozzles of the same type simultaneously. Different types of closed nozzles need to be pressurized separately to ensure that a safe air pressure is provided for different types of closed nozzles.

[0029] To monitor the pressure during the pressurization process of the closed-type nozzle and ensure safety, one of the interfaces 4 is also used to connect a pressure gauge. Each interface 4 has a first state for connecting the closed-type nozzle and a second state for connecting the pressure gauge. This application embodiment does not limit the specific interface 4 for connecting the pressure gauge. In this way, it can be ensured that the pressure required to meet the needs of the closed-type nozzle can be provided during the pressurization process, and the pressure can be monitored by the pressure gauge to ensure safety during the pressurization process.

[0030] During the pressurization process, in order to ensure a stable air pressure for multiple closed nozzles, the interface 4 is opened on the circumferential sidewall of the tapping component 3. This ensures that the direction of the pressurized gas supplied to the multiple closed nozzles is along the radial direction of the tapping component 3, thereby improving the stability of the pressurized gas supplied to the multiple closed nozzles.

[0031] To ensure sufficient air pressure inside the tapping component 3, the connecting hole is located at one end of the tapping component 3 in the axial direction, and the other end of the tapping component 3 in the axial direction is closed. In this way, the pressurized gas passing through the pressure table enters the tapping component 3 through the connecting hole and can only flow out through the interface 4, ensuring that the closed nozzle is provided with the required pressurized gas.

[0032] In some embodiments, the interface 4 may be distributed along the axial direction of the tap member 3, and there are at least two interfaces 4 along the axial direction of the tap member 3.

[0033] In some other embodiments, the interface 4 may be distributed along the circumference of the tap member 3, and there are at least two interfaces 4 along the circumference of the tap member 3.

[0034] In some other embodiments, at least two interfaces 4 are provided in both the axial and circumferential directions of the tapping component 3, but this application embodiment does not limit this.

[0035] For example, such as Figures 1-2 As shown, there are two interfaces 4 along the axial direction of the tapping component 3 and four interfaces 4 along the circumferential direction of the tapping component 3. This allows the tapping component 3 to pressurize eight closed nozzles simultaneously, further improving the pressurization efficiency.

[0036] To ensure the stability of the connection between the interface 4 and the closed nozzle, the tapping component 3 is a regular prism, and each side of the regular prism is provided with at least one interface 4. This allows the interface 4 and the closed nozzle to be connected in a plane, increasing the contact area between the closed nozzle and the interface 4, improving the stability of the connection between the interface 4 and the closed nozzle, and ensuring stable operation during the pressurization process of the closed nozzle.

[0037] In some embodiments, such as Figures 1-2 As shown, the tapping component 3 is a regular square prism (the sides of the square prism in the figure are chamfered), and each side of the square prism is provided with two interfaces 4, which further improves the working efficiency of the pressure test.

[0038] In some other embodiments, the tapping component 3 can be a regular triangular prism, a regular hexagonal prism, or a cylinder, etc., and this application does not limit this.

[0039] Because the connector of the closed nozzle is provided with a connecting thread, in some embodiments, the interface 4 is a threaded hole. This allows the closed nozzle to be directly threadedly connected to the interface 4, ensuring the stability of the connection between the closed nozzle and the interface 4.

[0040] In some other embodiments, the interface 4 is fixedly provided with a sealing element, such as a rubber ring or a rubber gasket, so that the closed nozzle can be directly inserted into the interface 4 along its axis, and the sealing element ensures the sealing of the connection between the closed nozzle and the interface 4, making the connection process between the closed nozzle and the interface 4 more convenient and further improving the working efficiency of the pressure testing process.

[0041] Since the tapping component 3 can pressurize multiple closed nozzles, when the number of interfaces 4 is greater than the number of closed nozzles that need to be pressurized, in order to ensure that the pressure of pressurizing the closed nozzles meets the requirements, it is necessary to seal the interfaces 4 that are not connected to closed nozzles by the sealing component 5. The sealing component 5 can be detachably and fixedly connected to the interface 4 to ensure that a stable pressure gas is provided to the closed nozzles that need to be pressurized.

[0042] like Figure 2As shown (the gap between interface 4 and sealing component 5 in the figure is only for easy identification; in reality, sealing component 5 can be sealed to interface 4), when interface 4 is a threaded hole, sealing component 5 is a threaded fastener. Threaded fasteners that can mate with the threaded hole can be used directly for connection, reducing component processing and manufacturing costs.

[0043] In some other embodiments, when a seal is provided on the inner wall of the interface 4, the sealing member 5 can be a light rod that can seal with the interface 4, making the connection process between the sealing member 5 and the interface 4 more convenient and further improving the working efficiency of the pressure testing process.

[0044] To ensure the stability of tap joint 3 during the pressurization process, such as Figures 1-2 As shown, the pressing device provided in this application embodiment also includes a base 1 and a support 2. The support 2 is fixedly connected to the tapping component 3, and the base 1 is fixedly connected to the support 2. The tapping component 3, the support 2, and the base 1 are distributed along the circumference of the tapping component 3. Of course, in order to provide stable support for the tapping component 3, the projected area of ​​the base 1 is larger than the projected area of ​​the tapping component 3 to ensure stable operation of the tapping component 3 during the pressing process.

[0045] To provide a passage for pressurized gas, the support member 2 is provided with a first through hole, and the base 1 is provided with a second through hole 101. The second through hole 101 is connected to the connecting hole of the tapping component 3 through the first through hole, and the second through hole 101 of the base 1 is used to connect to the pressure testing table. In this way, the pressurized gas provided by the pressure testing table can flow through the second through hole 101, through the first through hole, and then through the connecting hole into the connecting cavity of the tapping component 3. After that, it is delivered to each interface 4 through the connecting cavity to provide gas to the closed nozzle connected to the interface 4.

[0046] In practice, the pressurization table is sealed to the second through hole 101 via a plug-in air pipe to ensure the sealing of the pressurized gas during the pressurization process.

[0047] Of course, without the support 2 and the base 1, the plug-in air tube can be directly and sealed to the connection hole of the tap part 3.

[0048] When the pressure testing device provided in this application embodiment is working, the pressure testing device is first placed on the pressure testing platform and connected to the second through hole 101 through the plug-in air pipe of the pressure testing platform. Then, multiple closed nozzles that need to be pressured are connected to the interface 4, and a pressure gauge is connected to one of the interfaces 4. The remaining interfaces 4 are sealed by the sealing member 5. Then, the pressure testing platform is turned on, so that the pressurized gas provided by the pressure testing platform can flow through the second through hole 101 through the first through hole and then enter the connecting cavity of the tapping component 3 through the connecting hole. Then, it is delivered to each interface 4 through the connecting cavity to provide to the closed nozzles connected to the interface 4, thereby achieving synchronous pressure testing of multiple closed nozzles, improving the pressure testing efficiency of the closed nozzles, and improving the efficiency of fire protection maintenance.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
