Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "upper surface", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.
Referring to fig. 1-2, the present invention provides an embodiment: a container valve capable of conducting automatically comprises a valve body 1 arranged on a container opening, wherein a cavity 10 is further arranged inside the valve body 1; the cavity 10 is communicated with the interior of the container through a first channel 2, and the cavity 10 is communicated with the outside through a second channel 8; the cavity 10 is also internally provided with a valve core 3 for cutting off the first channel 2 and the second channel 8; one end of the valve core 3, which is far away from the first channel 2, is connected with a temperature sensing element 4; the temperature sensing element 4 is heated and then deforms or breaks when reaching a threshold value, so that the stress state of the valve core 3 is damaged, the valve core 3 moves upwards, the first channel 2 and the second channel 8 are communicated, and the fire extinguishing agent in the container is sprayed outwards.
In summary, when the valve body 1 is installed on a container, for example, in a container containing a fire extinguishing agent, and the container is installed in a place where fire is to be extinguished, then the temperature sensing element 4 is used to sense the outside temperature, when the outside temperature reaches the upper limit value of the temperature sensing element 4, the temperature sensing element 4 fails, and at this time, the temperature sensing element deforms or breaks, in short, the temperature sensing element 4 loses the original supporting capability, and at this time, the pressure inside the container pushes the valve element 3 to move upward, so that the first channel 2 and the second channel 8 are communicated, and the fire extinguishing agent inside the container is released through the second channel 8. Based on the structure, the equipment has a simple structure, can directly contact with the external temperature, does not need to be matched with other equipment, and does not have a complex electric circuit; thereby improving the reliability of the device when in use; particularly, the automatic conduction of the valve body 1 is realized by utilizing the unbalance of the temperature sensing element 4, and the factors disturbing the opening of the valve body 1 are reduced.
The temperature sensing element 4 can be made of glass-state material or thermoplastic plastic according to the temperature setting requirement in the area to be extinguished; for example, a polypropylene PP that softens at 120 ℃ or a PE material or wax that softens at 80 ℃ is selected, etc.
Furthermore, in order to fix the temperature sensing element 4 on the valve body 1, the temperature sensing element 4 can be connected to the valve body 1 through a bracket 5, so as to fix the temperature sensing element 4 on the other surface of the valve core 3.
Furthermore, the bracket 5 is connected with the valve body 1 through a valve cover 6, and the other end of the valve core 3 slides in the valve cover 6, because the valve core 3 can slide in the valve cover 6, when the temperature sensing element 4 is deformed or broken, the valve core 3 has a moving space so that the fire extinguishing agent can enter the second channel 8 from the first channel 2; in particular, the valve cover 6 can also prevent the valve core 3 from flying out of the valve body 1 and damaging related equipment in a fire extinguishing area.
Because the bracket 5 is a hollow structure, for example, the bracket 5 is arranged in a cylindrical shape, and then a plurality of notches, for example, three strip-shaped notches, are circumferentially arrayed on the circumferential surface of the bracket 5, and the notches completely penetrate through the bracket 5 along the radial direction of the bracket 5;
based on this, the temperature sensing element 4 in the support 5 can directly contact with the outside, and the interference of the support 5 on the sensing of the temperature sensing element 4 to the temperature is reduced, so that the temperature sensing element 4 can timely and rapidly react to the outside temperature.
Furthermore, the temperature sensing element 4 is abutted against the valve core 3 through the mutual matching of the provided fastening element 9 and the bracket 5.
Specifically, the bracket 5 is further provided with an internal threaded hole 11, and the fastening member 9 is in threaded fit with the internal threaded hole 11 to press the temperature sensing element 4 against the valve element 3. By the above mode, the assembly of the temperature sensing element 4 can be realized, and the disassembly of the temperature sensing element 4 is convenient. Particularly, the fixing mode has simple structure and mature technology, and greatly reduces the fixing cost of the temperature sensing element 4.
Furthermore, the opposite surfaces of the fastening element 9 and the valve element 3 are all abutted against the temperature sensing element 4 through the accommodating grooves 12, the two ends of the temperature sensing element 4 are reliably fixed due to the arrangement of the accommodating grooves 12, so that the stability of the temperature sensing element 4 after installation is improved, and the problem of position deviation caused by the fact that the contact surfaces of the temperature sensing element 4 with the end surface of the valve element 3 and the end surface of the fastening element 9 are few when the temperature sensing element 4 is installed can be avoided.
In summary, the temperature sensing element 4 is reliably fixed; secondly, the valve core 3, the temperature sensing element 4, the bracket 5 and other parts are convenient to assemble together; and thirdly, the assembly steps of the parts are simplified so as to facilitate the later maintenance of the equipment.
On the basis of the scheme, because the valve body 1 is also provided with the inflating nozzle 7, when in use, an air nozzle, such as a valve core, is arranged on the inflating nozzle 7, so that the inside of the valve body 1 can be inflated through the inflating nozzle 7, and further the inside of the container is inflated; in addition, the pressure relief hole 13 is internally provided with a rupture disk under a normal state, and when the internal pressure of the container exceeds the pressure born by the rupture disk, the rupture disk is ruptured to release the internal pressure of the container, so as to avoid the condition that the container explodes. In addition, the structure of the charging connector 7 and the relief hole 13 is the same as the design of the existing valve body, so that the description is omitted.
Preferably, the parameters of the temperature sensing element 4 are as follows: Φ 5mmYD glass ball, operating temperature: 79 ℃; the length of the glass ball is 20mm; or phi 5mmYD glass balls, operating temperature: 93 ℃; the length of the glass ball is 20mm.
Therefore, when the valve body 1 is installed on a fire extinguishing bottle, after the temperature sensing element 4 fails due to external temperature, the fire extinguishing agent in the fire extinguishing bottle can be automatically sprayed out to complete the automatic fire extinguishing work, and the glass ball is convenient to purchase, so that the use and maintenance cost of the device can be further reduced.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and these embodiments are still within the scope of the invention.
