Description

Technical Field

[0001] This utility model relates to container valves, and more particularly to a container valve with an adjustable sensor connector position and its fire extinguishing equipment. Background Technology

[0002] In the field of fire protection equipment, such as fire-fighting devices placed in cabinets (patent number: CN117815610A), the installation of pressure sensors faces certain limitations. In this patented technical solution, the pressure sensor in the driving gas cylinder group is fixedly installed on the driving gas cylinder body. This fixed installation method prevents the pressure sensor from rotating. In actual installation, due to the complex internal space structure of the cabinet and the compact layout of various equipment and pipes, the fixed installation position of the pressure sensor can easily interfere with other components. For example, in a small fire-fighting equipment box, the driving gas cylinder body may be surrounded by extinguishing agent cylinder groups, various pipes, and controllers. It is difficult to find a suitable angle and position for the pressure sensor during installation, leading to installation difficulties and potentially affecting its normal monitoring function due to positional deviation.

[0003] Furthermore, when maintenance, repair, or upgrades of fire-fighting equipment are required, the fixed and non-rotatable position of the pressure sensor restricts operating space, making disassembly, replacement, or adjustment extremely inconvenient and increasing maintenance and time costs. This installation method cannot meet the practical needs for flexible installation and adjustment of pressure sensors, thus limiting the performance optimization and application expansion of fire-fighting equipment to some extent. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a container valve with an adjustable sensor connector position and its fire extinguishing device.

[0007] A sensor connector for installing a sensor is installed between the valve gauge connector and the bottle head valve body. The sensor connector is fitted onto the valve gauge connector and communicates with it. When the valve gauge connector is loosened, the sensor connector can rotate around the valve gauge connector.

[0008] Preferably, the lower end of the valve gauge connector is axially limited on the bottle head valve body and threadedly connected thereto, and the valve gauge connector and the bottle head valve body are sealed together by a first sealing element.

[0009] Preferably, the valve gauge connector is provided with a valve gauge channel communicating with the container, and the valve gauge connector is also provided with a vent hole communicating with the valve gauge channel.

[0010] Preferably, the valve connector is fitted with a second seal and a third seal, which are respectively located at the upper and lower ends of the vent hole. The inner wall of the sensor connector is sealed to the valve connector through the second and third seals.

[0011] Preferably, the upper and lower end faces of the sensor connector are equipped with a fourth seal and a fifth seal. The sensor connector is sealed to the valve connector through the fourth seal and to the bottle valve body through the fifth seal.

[0012] Preferably, a second valve core is installed in the axial direction of the valve gauge connector.

[0013] Preferably, the top end of the valve connector is secured with two locking nuts, and a washer is installed between the two locking nuts.

[0014] Fire extinguishing equipment includes a container with a container valve on which the sensor connector position is adjustable, a pressure gauge installed at the end of the valve gauge connector, and a pressure sensor installed on the sensor connector.

[0015] Preferably, the sensor connector is equipped with a push pin and a first valve core, and the pressure sensor is connected to the first valve core through the push pin.

[0016] This utility model, by adopting the above technical solution, has significant technical effects:

[0017] Traditional sensors have fixed installation positions, making them prone to interference with other components in complex equipment environments.

Even in confined equipment spaces, suitable installation points can be found, significantly reducing installation difficulty and improving installation efficiency. Attached Figure Description

[0027] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described in detail with reference to the embodiments.

[0028] Example 1

[0029] The container valve with adjustable sensor connector position includes a bottle head valve body 10 mounted on the container, and a valve gauge connector 11 communicating with the container is tightly fitted onto the bottle head valve body 10.

[0030] A sensor connector 12 for installing a sensor is installed between the valve connector 11 and the bottle valve body 10. The sensor connector 12 is fitted onto the valve connector 11 and communicates with it. When the valve connector 11 is loosened, the sensor connector 12 can rotate around the valve connector 11.

[0031] Under normal circumstances, the valve gauge connector 11 is in a tight state. When it is necessary to adjust the sensor position, loosen the valve gauge connector 11. At this time, the sensor connector 12 can rotate around the valve gauge connector 11, thereby realizing the adjustment of the sensor position.

[0032] In actual installation, the internal space of equipment is usually quite complex, with various components arranged compactly. Traditional fixed-position sensor installation methods often struggle to find suitable installation points due to space constraints, and may even interfere with other components. However, the sensor connector 12 of this container valve can rotate around the valve gauge connector 11, allowing installers to flexibly adjust the angle and position of the sensor according to the actual situation, easily avoiding surrounding components, greatly reducing installation difficulty and improving installation efficiency.

[0033] The lower end of the valve connector 11 is axially limited on the bottle head valve body 10 and threadedly connected to it. The lower end of the valve connector 11 extends to the bottom of the bottle head valve body 10. The valve connector 11 and the bottle head valve body 10 are sealed together by a first sealing element 13, which is an O-ring. The first sealing element 13 prevents air pressure from leaking between the valve connector 11 and the bottle head valve body 10.

[0034] The valve connector 11 is provided with a valve channel 111 communicating with the container, and a vent 112 communicating with the valve channel 111. A first valve core 14 is installed on the sensor connector 12. An annular chamber 100 is formed between the first valve core 14, the sensor connector 12, and the valve connector 11. The chamber 100 communicates with the valve channel 111 through the vent 112. Since the sensor connector 12 can rotate on the valve connector 11, regardless of its rotation position, the chamber 100 can communicate with the valve channel 111 through the vent 112, thus facilitating the sensor on the sensor connector 12 to monitor the pressure within the valve channel 111.

[0035] A second seal 15 and a third seal 16 are fitted onto the valve gauge connector 11. Both the second seal 15 and the third seal 16 are O-rings. Two annular grooves are provided on the outer circumference of the valve gauge connector 11. The second seal 15 and the third seal 16 are respectively installed in their respective annular grooves, forming a radial seal. The second seal 15 and the third seal 16 are respectively located at the upper and lower ends of the vent hole 112 to prevent gas in the valve gauge channel 111 from leaking between the sensor connector 12 and the valve gauge connector 11. The inner wall of the sensor connector 12 is sealed to the valve gauge connector 11 through the second seal 15 and the third seal 16.

[0036] The upper and lower end faces of the sensor connector 12 are equipped with a fourth sealing element 17 and a fifth sealing element 18. Both the fourth sealing element 17 and the fifth sealing element 18 are O-rings. Both the upper and lower end faces of the sensor connector 12 are provided with annular grooves. The fourth sealing element 17 and the fifth sealing element 18 are respectively installed in their respective annular grooves. The fourth sealing element 17 and the fifth sealing element 18 further strengthen the seal between the bottle head valve body 10, the valve gauge connector 11 and the sensor connector 12. The sensor connector 12 is sealed to the valve gauge connector 11 through the fourth sealing element 17 and to the bottle head valve body 10 through the fifth sealing element 18. When the valve gauge connector 11 is tightened, the fourth sealing element 17 is pressed between the valve gauge connector 11 and the sensor connector 12, and the fifth sealing element 18 is pressed between the bottle head valve body 10 and the sensor connector 12.

[0037] A second valve core 19 is installed in the axial direction of the valve gauge connector 11. The second valve core 19 is in the closed state under the action of the spring. When the second valve core 19 is pushed open, the second valve core 19 is in the open state, and the pressure gauge 22 connected to the valve gauge connector 11 can display the pressure value inside the container.

[0038] The top end of the valve connector 11 is secured with two locking nuts 20, and a washer 21 is installed between the two locking nuts 20. The two locking nuts 20 can secure the container valve to the housing, and the port of the valve connector 11 is exposed outside the housing.

[0039] Example 2

[0040] The fire extinguishing equipment includes a container with an adjustable container valve (as described in Embodiment 1) installed on the container. A pressure gauge 22 is installed at the end of the valve connector 11. The pressure gauge 22 is used to monitor the pressure value inside the container. This pressure gauge 22 is a mechanical pressure gauge, but in other embodiments it can also be described as a digital pressure gauge. A pressure sensor 23 is installed on the sensor connector 12. The pressure sensor 23 can monitor the changes in the pressure value inside the container in real time, thereby realizing remote monitoring of whether the fire extinguishing equipment has been activated.

[0041] The sensor connector 12 is equipped with a push pin 24 and a first valve core 14, and the pressure sensor 23 is connected to the first valve core 14 through the push pin 24.
