Description

Technical Field

[0001] The utility model relates to a main control valve, in particular to a main control valve suitable for a kitchen fire fighting tank. Background Art

[0002] For the current kitchen fire protection system, in order to achieve the rapid delivery of fire extinguishing media such as foam or nitrogen, corresponding pipelines and tanks are configured. The commonly used triggering method is to use an external temperature sensing device to control the puncture assembly to puncture the release film on the upper end of the tank with gravitational potential energy. However, this structure requires a longer release channel to be reserved, occupying the box space where the tank is placed. At the same time, there are many false contact points in its use, which is prone to false triggering during assembly, resulting in the scrapping of the tank.

[0003] At present, there are also mechanisms that use springs to cooperate with the acupuncture components and use elastic force to puncture and release. However, the spring is directly connected to the steel wire that matches the consumer system, and only a simple release buckle is used to put the spring in a compressed state ready to fire. When the spring is in a compressed state for a long time, if there is external vibration, or the steel wire undergoes slight deformation due to thermal expansion and contraction due to temperature changes in daily use of the stove, it is easy to cause the release buckle to be triggered by mistake, and the use is not very stable.

[0004] Furthermore, there are also solenoid valves to control the acupuncture components, which requires effective signal data communication, is prone to failure in a high smoke environment, and requires an additional placement box.

[0037] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0038] like Figures 1 to 2The main control valve suitable for the kitchen fire fighting tank body includes a valve base 1, which is different in that: the lower end of the valve base 1 is provided with a connection guide component, which can connect the kitchen fire fighting tank body and the corresponding fire fighting pipeline. At the same time, a bearing bracket 2 is provided at the upper end of the valve base 1, and a longitudinal guide groove 3 is provided on the bearing bracket 2. The position of the bearing bracket 2 corresponding to the connection guide component is provided with a firing component, which is convenient for firing the tank body to release the corresponding gas or foam when a fire hazard occurs. In addition, in order to connect the external high temperature sensing device, the firing component is provided with a transverse lever 4, and the transverse lever 4 is movably connected with a receiving and releasing component. Specifically, the receiving and releasing component is provided with a bearing cross bar 5, and the bearing cross bar 5 is connected with a conducting component. The connecting guide component includes a connecting sleeve 6, and the connecting sleeve 6 is provided with a conductive air inlet port 7 and an air outlet port 8. During the implementation, when in the ready-to-fire state, the receiving and releasing component is connected to the firing component. In this way, under the action of the receiving and releasing component, the firing component can be in a standby state. After the firing assembly is separated from the receiving and releasing assembly, the tank body connected thereto can be started for firing.

[0039] In view of a preferred embodiment of the utility model, the load-bearing bracket 2 includes a base connected to the connecting guide assembly, so that it is convenient to connect to the inner side of the box body of the fire-fighting equipment through the base. A bracket body is arranged on the base, and a longitudinal guide groove 3 is provided in the bracket body, and the firing assembly is movably connected to the longitudinal guide groove 3. In this way, the movement of the firing assembly can be guided by the longitudinal guide groove 3. At the same time, a reinforcement strip (not shown in the figure) is arranged on the bracket body to improve the overall rigidity. In addition, a lateral mounting hole (not shown in the figure) is arranged on the bracket body to facilitate connection with the corresponding box body.

[0040] Further, the firing assembly includes a pin module 9 movably arranged in the support bracket 2, a transverse lever 4 is arranged on the pin module 9, and a force spring 10 is arranged on the upper end of the pin module 9, and the force spring 10 is in contact with the top of the support bracket 2. When in the ready-to-fire state, the receiving and releasing assembly contacts the transverse lever 4, so that the force spring 10 is in a compressed state. In this way, when the receiving and releasing assembly is separated from the transverse lever 4, the stress applied by the force spring 10 can make the pin module 9 rush toward the tank body, and then pierce the seal at the upper end of the tank body, so as to release the corresponding gas or fire extinguishing agent.

[0041] In view of the actual implementation, the receiving release component includes a concave-shaped release sheet 11, which is connected to the bearing bracket 2 through a rotating shaft. Specifically, in order to fit the bearing bracket 2 for distribution, the concave-shaped release sheet 11 is semi-enclosed and distributed on the periphery of the bearing bracket 2, and the lower end of the concave-shaped release sheet 11 is provided with a pair of hooks 12, and the upper end of the concave-shaped release sheet 11 is provided with a bearing cross bar 5. At the same time, the bearing cross bar 5 is connected to the conduction component, and when it is in the ready-to-fire state, the hook 12 is movably connected to the transverse gear bar 4. Specifically, the hook 12 is provided with an oblique release edge 13, and the inclination angle of the oblique release edge 13 is 5 to 35 degrees. In this way, when the concave-shaped release sheet 11 is released by conduction, its hook 12 can quickly slide off the transverse gear bar 4 to achieve timely release. In addition, the upper end of the concave-shaped release sheet 11 is provided with a pair of extended fins 14, and a docking rod 20 is provided between the extended fins 14. In this way, the release stroke of the concave-shaped release sheet 11 during actual use can be shortened, thereby reducing the release waiting time.

[0042] Further, in order to better transmit the release stress brought by the external conductive medium such as the traction wire, the conductive component used includes a Z-shaped conductive plate 15. A clamp ring 16 is provided at one end of the Z-shaped conductive plate 15, and the clamp ring 16 is connected to the docking rod 20. In addition, a conductive terminal 21 is provided at the other end of the Z-shaped conductive plate 15. Furthermore, considering the convenient connection between itself and the bearing bracket 2, a connecting edge 17 is provided on the Z-shaped conductive plate 15, and a conductive shaft 18 is penetrated on the connecting edge 17, and the conductive shaft 18 is connected to the bearing bracket 2. Considering the convenience of debugging after assembly, an auxiliary handle 19 is provided on the Z-shaped conductive plate 15. In this way, the assembler can hold the auxiliary handle 19 to simulate the release of the entire main control valve and adjust the final movement stroke of the firing assembly to facilitate the puncture needs during formal use. Furthermore, in order to smoothly dock with the release wire that is usually adapted to the medium-temperature sensing device of the kitchen fire protection system, the conductive terminal 21 includes a guide column, and a locking cap is provided on the guide column. In this way, the release wire can be wound through the guide post and locked through the locking cap.

[0043] Considering the need to connect with the preset pipeline to meet the actual needs of gas or liquid transmission, the connecting sleeve 6 is distributed in a 7-shaped manner, with the air inlet port 7 located at the lower end and the air outlet port 8 located at the side end of the connecting sleeve 6. In this way, the layout needs of upper end piercing, lower end input, and side end single-sided output can be achieved. In order to meet the layout needs of some multi-spray systems of the needle, the connecting sleeve 6 can also be distributed in a T-shaped manner, with the air inlet port 7 located at the lower end and two air outlet ports 8, which are mirror-distributed on both sides of the connecting sleeve 6. In this way, the needs of upper end piercing, lower end input, and bilateral synchronous output can be met. Furthermore, considering the need for airtightness after connecting with the pipeline, the air inlet port 7 and the air outlet port 8 are provided with connecting flanges 22.

[0044] The working principle of the utility model is as follows:

[0045] When a high temperature condition occurs, the high temperature sensing device is broken by the heat and released, causing the holding stress provided by the release wire to also be released.

[0046] At the same time, the conducting end 21 of the Z-shaped conducting plate 15 of the conducting assembly loses its holding stress, and it uses the conducting shaft 18 as a fulcrum to perform a downward tilting motion, and exerts force on the extended fin 14 of the concave-shaped release sheet 11, so that it pries the concave-shaped release sheet 11 with the bearing cross bar 5 as the axis. As a result, the transverse bar 4 slips out of the hook 12.

[0047] In this way, the force spring 10 is reset and released instantly, so that the ejector module 9 impacts downward, contacts the upper end of the tank body through the channel at the upper end of the connecting sleeve, performs a piercing operation, and realizes the release of the substance in the tank.

[0048] During this period, in order to avoid the release jam, the transverse lever 4 used includes a baffle body, and a POM self-lubricating sleeve is provided on the baffle body outer cover. In this way, as long as the concave-shaped release sheet 11 has a tendency to release, the transverse lever 4 can quickly slip off from the hook 12.

[0049] It can be seen from the above text description and the accompanying drawings that the following advantages are achieved after adopting the utility model:

[0050] 1. Adapt to the release wire release transmission of the current kitchen fire protection system, realize physical transmission, do not need to configure electronic release valve body, reduce implementation cost, and have better mechanical stability.

[0051] 2. The load-bearing cross bar and the hook are used to reduce the release stroke, without the need to add a complex release mechanism, without providing additional unlocking or releasing external force, and there will be no release jam.

[0052] 3. The firing component can instantly puncture the tank body and, with the cooperation of the corresponding pipelines of the kitchen fire protection system, extinguish the fire source and cool down the site. There is no need to add solenoid valves to assist in the firing of the tank body. The response time is short and the operation is stable.

[0053] 4. The overall mechanical structure adopts a simple layout, does not require the participation of electronic devices, has good operating stability, and is easy to manufacture and use.

[0054] In addition, the indicated orientations or positional relationships described in the present invention are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or structure referred to must have a specific orientation or be operated with a specific orientation structure. Therefore, they cannot be understood as a limitation on the present invention.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
