Description

Technical Field

[0001] This invention belongs to the technical field of rain alarm valves, specifically relating to a rain alarm valve manual ball valve anti-misoperation device and system. Background Technology

[0002] As a key component of fire extinguishing systems, deluge alarm valves are directly related to the safety of fire protection systems. Their purpose is to activate the fire extinguishing system in a timely manner in the event of a fire, thereby protecting the safety of personnel and equipment in the area and minimizing water damage.

[0003] According to GB5135.5, deluge alarm valves must have a mechanical opening mechanism, and some deluge alarm valve manufacturers also install remote mechanical opening devices. Therefore, the control pipeline of the deluge alarm valve is equipped with one or more manual ball valves for manually opening the deluge alarm valve. If these ball valves are accidentally opened, the deluge alarm valve will open, allowing fire water to enter the system side and spray directly into the protected area, endangering the safety of equipment and personnel in the protected area.

[0004] According to GB5135.5, deluge alarm valves are classified into pressure-reducing and pressure-boosting types. Pressure-reducing deluge alarm valves: When the manual ball valve is opened, the pressure in the control chamber decreases, creating a pressure difference between the control chamber and the inlet chamber, causing the diaphragm to displace and thus opening the deluge alarm valve. Pressure-boosting deluge alarm valves: When the manual ball valve is opened, the pressure in the control chamber increases, creating a thrust on the piston assembly, causing the piston assembly to displace and thus opening the deluge alarm valve.

[0005] The manual ball valves in the control pipelines of existing fire protection systems' deluge alarm valves are not equipped with devices to prevent accidental operation. Therefore, it is necessary to upgrade and improve the control pipelines of deluge alarm valves while meeting national standards. Summary of the Invention

[0006] The purpose of this invention is to provide a device and system for preventing misoperation of the manual ball valve of a deluge alarm valve, so as to solve the technical problem that the manual ball valve in the control pipeline of the deluge alarm valve in the prior art does not have a device to prevent its misoperation.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] In a first aspect, the present invention provides a device for preventing misoperation of a manual ball valve for a rain alarm valve, comprising a valve body, a valve cover connected to the end of the valve body, and a snap-fit ​​assembly. The valve body and the valve cover are connected by a sealing device to form a sealed cavity structure, and a valve core is provided in the cavity inside the valve body. One end of the valve core is connected to the valve cover, and the other end is connected to the inner wall of the valve body by a spring.

[0009] The valve core is configured as a columnar structure, and the valve core has a number of through holes arranged axially. The valve core end is provided with a flow guide groove. One end of the spring is sleeved on the outer periphery of the flow guide groove of the columnar valve core, and the other end abuts against the inner wall of the valve body.

[0010] The snap-fit ​​assembly includes a fixed section and a snap-fit ​​section. A flexible tube assembly is also connected to the end of the snap-fit ​​section. A short tube is also snap-fitted to the outer periphery of the snap-fit ​​section, and the short tube fits the flexible tube assembly.

[0011] By combining the valve cover and valve body to form a chamber, and placing the valve core inside the chamber with one end of the valve core against the inner wall of the valve body via a spring, when the manual ball valve in the deluge alarm valve control pipeline is accidentally opened, the fire water pressure in the deluge alarm valve servo-state pressure stabilization system is insufficient to open the manual ball valve anti-misoperation device, thus preventing the accidental opening of the deluge alarm valve. This effectively solves the equipment failure and operator safety problems caused by the accidental opening of the manual ball valve in the deluge alarm valve control pipeline.

[0012] Optionally, the sealing device includes a connecting post, which is located at the other end of the valve core opposite to the guide groove. The connecting post is provided with an annular groove, and an O-ring is snapped into the annular groove. The O-ring is fitted and sealed to the cavity wall in the valve cover.

[0013] Optionally, the snap-fit ​​section is configured as a tubular structure with a gradually decreasing diameter towards the outer end. By configuring the tubular structure with a gradually decreasing diameter, it can be connected to short pipes of different diameters. Furthermore, the outer periphery of the snap-fit ​​section is provided with several snap-fit ​​grooves to facilitate snap-fitting of the short pipes. The short pipes are effectively fixed by configuring several snap-fit ​​grooves.

[0014] Optionally, a fixing ring is provided on the outer periphery of the fixing section, a fixing post is fixedly provided on the fixing ring, and a limit spring rope is connected to the fixing post.

[0015] Optionally, the clamping assembly further includes a clamp, which is provided with a connection hole for connecting with a limiting spring rope, and the inner wall of the clamp for clamping the short pipe is also provided with a limiting ring.

[0016] In the above technical solution, a clamp is used to clamp the short pipe to the outer periphery of the clamping section, and the clamp is connected to the fixed pile with a limiting spring rope to increase the stability of the short pipe connection.

[0017] Optionally, the flexible tube assembly includes a connecting tube threadedly connected to the snap-fit ​​section. The end of the connecting tube is provided with a tension tube, which has an outwardly opening and gradually expanding diameter structure. An elastic tube is provided at the opening of the tension tube. By providing the tension tube and the elastic tube, support is achieved inside the short tube, and the connection of the short tube is prevented from breaking due to long-term bending.

[0018] Optionally, it also includes a signal component, which includes a threaded short pipe, a tee, and a pressure switch. The tee has a T-shaped structure, and one end of the tee is connected to the threaded short pipe. The end of the threaded short pipe perpendicular to the connection end of the tee is also connected to the pressure switch.

[0019] In the above technical solution, when the anti-misoperation device of the manual ball valve of the deluge alarm valve is opened, the pressure switch senses the water pressure in the pipeline and transmits the pressure to the signal terminal of the relevant personnel, so that the operating status of the deluge alarm valve can be monitored remotely in real time.

[0020] In a second aspect, the present invention also provides a system for an anti-misoperation device for a manual ball valve of a deluge alarm valve according to any one of the first aspects, comprising:

[0021] For selecting a pressure-reducing or pressure-boosting deluge alarm valve and connecting it to the anti-misoperation device of the manual ball valve of the deluge alarm valve, the anti-misoperation device of the manual ball valve of the deluge alarm valve further includes connecting the other end of the valve body and the valve cover opposite to the fixed section, the snap-fit ​​section is threadedly connected to the connecting pipe, the short pipe sleeves the flexible pipe assembly inside and is connected to the snap-fit ​​section by a clamp, and the output end of the short pipe is connected to the manual ball valve.

[0022] Optionally, the connection between the selectable pressure-reducing or pressure-boosting deluge alarm valve and the manual ball valve anti-misoperation device for the deluge alarm valve includes:

[0023] If a pressure-reducing deluge alarm valve is selected, the anti-misoperation device of the manual ball valve of the deluge alarm valve is connected to the control chamber of the pressure-reducing deluge alarm valve.

[0024] If a pressurized deluge alarm valve is selected, the anti-misoperation device of the manual ball valve of the deluge alarm valve is connected to the inlet of the pressurized deluge alarm valve, and the manual ball valve is connected to the control chamber of the pressurized deluge alarm valve.

[0025] Optionally, the signal component is connected to the outlet of the pressure-reducing or pressure-increasing deluge alarm valve, and the signal component includes:

[0026] Signal transmitting module: used to transmit pressure signals;

[0027] Signal receiving module: used to receive pressure signals;

[0028] Signal processing module: Used to process and display the received pressure signals.

[0029] The beneficial effects and advantages of this invention are as follows:

[0030] By combining the valve cover and valve body to form a chamber, the valve core is located inside the chamber, and one end of the valve core is abutted against the inner wall of the valve body by a spring. When the manual ball valve in the deluge alarm valve control pipeline is accidentally opened, the fire water pressure in the deluge alarm valve servo pressure stabilization system is insufficient to open the manual ball valve anti-misoperation device, thus avoiding the accidental opening of the deluge alarm valve. This effectively solves the equipment failure and operator safety problems caused by the accidental opening of the manual ball valve in the deluge alarm valve control pipeline.

[0031] The system achieves rapid connection with short pipes by setting up snap-fit ​​components, connects with short pipes of different diameters by setting up tubular structures with gradually decreasing diameters, and snaps are used to snap the short pipes onto the outer periphery of the snap-fit ​​section. In addition, the connection between the snaps and the fixing piles is limited by spring ropes to increase the stability of the connected short pipes.

[0032] By setting up a signal component, the fire water pressure in the control pipeline of the deluge alarm valve is transmitted in real time to the signal terminal of relevant personnel, so as to realize real-time remote monitoring of the operating status of the deluge alarm valve.

Detailed Implementation

[0039] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0040] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are used only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0041] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] Example 1

[0043] like Figure 1 and Figure 2 As shown, this embodiment provides a device to prevent misoperation of a manual ball valve for a rain alarm valve, including a valve cover 1 and a valve body 5 connected to the valve cover 1 to form a cavity;

[0044] refer to Figure 1 and Figure 2 As shown, in this embodiment, after the valve cover 1 is connected to the valve body 5, its interior is set as a cavity, in which a valve core 3 is set. The valve core 3 is preferably set as a columnar structure and has an axial structure with an array of through holes. The valve core 3 also has a guide groove 31 at its end, and the structure of the valve core 3 with the array of through holes abuts against the inner wall of the cavity. In this embodiment, the valve core 3 is also fitted with a spring 4, and one end of the spring 4 is fitted on the outer periphery of the flow groove of the columnar structure valve core 3, and the other end abuts against the inner wall of the valve body 5.

[0045] In this embodiment, a connecting post is provided at the other end of the valve core (3) connected to the guide groove 31. The connecting post is surrounded by an annular groove, and an O-ring 2 is snapped into the annular groove. The O-ring 2 is fitted and sealed to the cavity wall in the valve cover 1.

[0046] In this embodiment, based on the system stabilizing pressure P (unit: Pa) and the force-bearing area S of the valve core (unit: square meter), the water pressure F (unit: Newton) borne by the valve core is calculated using F=P×S. When selecting the spring, it is preferable to ensure that the elastic force of the spring when it is compressed to its limit working position is greater than the water pressure F borne by the valve core, so that the valve core moves axially under the action of water pressure, causing the anti-misoperation device of the manual ball valve of the deluge alarm valve to be activated. Pressurized water flows through the anti-misoperation device of the manual ball valve of the deluge alarm valve, changing the pressure in the control chamber of the deluge alarm valve and opening the deluge alarm valve.

[0047] In use, the valve cover 1 and valve body 5 are combined to form a chamber. The valve core 3 is located inside the chamber, and one end of the valve core 3 is abutted against the inner wall of the valve body 5 by a spring 4. When the manual ball valve in the deluge alarm valve control pipeline is accidentally opened, the fire water pressure in the deluge alarm valve servo pressure stabilization system is insufficient to open the deluge alarm valve manual ball valve anti-misoperation device, thus avoiding the accidental opening of the deluge alarm valve. This effectively solves the equipment failure and operator safety problems caused by the accidental opening of the deluge alarm valve due to the accidental opening of the manual ball valve in the deluge alarm valve control pipeline.

[0048] refer to Figure 3 and Figure 4 As shown, this embodiment also provides a snap-fit ​​assembly 6, wherein one end of the snap-fit ​​assembly 6 is connected to the valve body 5, and the other end is fitted with a connecting short tube 8.

[0049] In this embodiment, the snap-fit ​​assembly 6 includes a fixed section 61 and a snap-fit ​​section 62. The fixed section 61 is used to connect with the output port of the valve body 5. The connection method can be achieved by snap-fit ​​or threaded connection methods in the prior art. The end of the snap-fit ​​section 62 is provided with a detachable flexible tube assembly 7. The flexible tube assembly 7 is used to fit into the short tube 8 to prevent the connection of the short tube 8 from being in a bent state for a long time and thus breaking.

[0050] refer to Figure 3 and Figure 4 As shown, in this embodiment, the snap-fit ​​section 62 is configured as a tubular structure with a gradually decreasing diameter towards the outer end, and the outer periphery of the snap-fit ​​section 62 preferably has a plurality of snap-fit ​​grooves 621 axially provided to facilitate snap-fit ​​of the short pipe 8.

[0051] In this embodiment, the snap-fit ​​assembly 6 also includes a clamp 63 adapted to the snap-fit ​​groove 621. The width of the clamp 63 is adapted to the snap-fit ​​groove 621. In use, the short pipe 8 is fitted into the snap-fit ​​section 62. By setting a tubular structure with a gradually decreasing diameter at the outer end, it can be used for short pipes 8 of different diameters. After the short pipe 8 is fitted into the groove, it is adjusted and fixed by the clamp 63.

[0052] In this embodiment, a fixing ring 611 is provided on the outer periphery of the fixing section 61, and a fixing post 612 is fixedly provided on the fixing ring 611. A limiting spring rope 613 is connected to the fixing post 612. A connecting hole 631 is also provided on the clamp 63. The other end of the limiting spring rope 613 is connected and fixed to the connecting hole 631, which increases the stability of the overall clamping assembly 6 connection. The clamp 63 is used to clamp the inner wall of the short pipe 8 and is also provided with a limiting ring 632. When in use, the limiting ring 632 is sleeved on the outside of the short pipe 8 and clamped into the clamping groove 621, which increases the friction of the clamping and increases the connection stability.

[0053] refer to Figure 3 and Figure 4 As shown, in this embodiment, the flexible tube assembly 7 includes a connecting tube 71 threadedly connected to the snap-fit ​​section 62. The end of the connecting tube 71 is provided with a tension tube 72, which has an open structure, and an elastic tube 73 is provided at the opening of the tension tube 72. In this embodiment, the tension tube 72 and the elastic tube 73 are preferably made of elastic materials such as rubber tubes in the prior art. In this embodiment, by providing a detachable connecting tube 71, the operator can choose whether to connect the flexible tube assembly 7. Furthermore, by providing the tension tube 72 and the elastic tube 73 made of elastic material, bending can be achieved, so as to prevent the short tube 8 from being in a bent state for a long time and breaking.

[0054] refer to Figure 5 As shown, this embodiment also provides a signal component 9, which includes a threaded short pipe 91, a tee 92 and a pressure switch 93. The tee 92 is preferably configured as a T-shaped structure, and the end of the tee 92 is connected to the threaded short pipe 91. The end of the threaded short pipe 91 that is perpendicular to the connection end of the tee 92 is also connected to the pressure switch 93.

[0055] By setting up signal component 9, the fire water pressure in the control pipeline of the deluge alarm valve is transmitted to the signal terminal of relevant personnel in real time, so as to realize real-time remote monitoring of the operation status of the deluge alarm valve.

[0056] In this embodiment, regarding the deluge alarm valve as a whole, if the manual ball valve in the deluge alarm valve control pipeline is accidentally opened, the deluge alarm valve will be opened unexpectedly, allowing fire water to enter the system and spray directly into the protected area, endangering the safety of equipment and personnel within the protected area.

[0057] When the manual ball valve in the deluge alarm valve control line is accidentally opened, the stabilizing pressure is insufficient to open the anti-misoperation device of the manual ball valve of the deluge alarm valve, thus preventing the deluge alarm valve from being opened unexpectedly.

[0058] However, the control pipelines of different series and specifications of deluge alarm valves are not the same. In order to facilitate the installation of the anti-misoperation device of the manual ball valve of the deluge alarm valve, a snap-fit ​​component 6 is set. By setting the snap-fit ​​section 62 as a tubular structure with a gradually decreasing diameter, it can be quickly connected to control pipelines of different diameters. By setting the clamp 63, the short pipe 8 can be snapped into the outer periphery of the snap-fit ​​section 62, and the clamp 63 is connected to the fixed pile 612 with a limit spring rope 613 to increase the stability of the connection.

[0059] To ensure that relevant personnel can monitor the operation status of the deluge alarm valve in real time, a signal component is installed at the valve's outlet. The signal component is installed at the outlet of the deluge alarm valve via a threaded short pipe. When the deluge alarm valve is in standby mode, the signal component outputs no pressure signal, indicating that the deluge alarm valve is closed. When the system pressure increases, the deluge alarm valve opens, and pressurized water enters the outlet from the inlet. The signal component senses the water pressure in the pipeline and transmits the pressure to the signal terminal of the relevant personnel, indicating that the deluge alarm valve has opened. This allows for remote, real-time monitoring of the deluge alarm valve's operation status.

[0062] refer to Figures 1 to 5 As shown, in this embodiment, for the selection of pressure-reducing or pressure-boosting deluge alarm valve and the connection of the deluge alarm valve manual ball valve anti-misoperation device, the deluge alarm valve manual ball valve anti-misoperation device in this embodiment also includes connecting the output end of the valve body 5 to the fixed section 61, wherein the snap-fit ​​section 62 is threadedly connected to the connecting pipe 71, and the short pipe 8, after fitting the flexible pipe assembly 7 inside, is connected to the snap-fit ​​section 62 through the clamp 63, and the output end of the short pipe 8 is connected to the manual ball valve.

[0063] In this embodiment, if a pressure-reducing deluge alarm valve is selected, the anti-misoperation device of the manual ball valve of the deluge alarm valve is connected to the control chamber of the pressure-reducing deluge alarm valve. If a pressure-boosting deluge alarm valve is selected, the anti-misoperation device of the manual ball valve of the deluge alarm valve is connected to the inlet of the pressure-boosting deluge alarm valve, and the manual ball valve is connected to the control chamber of the pressure-boosting deluge alarm valve. Different connection relationships are selected for the structure and working characteristics of the pressure-reducing and pressure-boosting deluge alarm valves to achieve the function of preventing misoperation in both types.

[0064] In this embodiment, the signal component 9 is connected to the outlet of a pressure-reducing or pressure-boosting deluge alarm valve in the prior art, and the signal component 9 in this embodiment includes:

[0065] Signal transmitting module: used to transmit pressure signals;

[0066] Signal receiving module: used to receive pressure signals;

[0067] Signal processing module: Used to process and display the received pressure signals.

However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
