Description

Technical Field

[0001] The utility model relates to the technical field of butterfly valves, and more specifically to a fire signal quick prompt butterfly valve. Background Art

[0002] The signal butterfly valve is a special type of butterfly valve, mainly used in automatic fire water supply systems. It combines the switch function of the traditional butterfly valve with the signal feedback mechanism. The butterfly valve itself is a valve that opens or closes the pipeline by rotating the valve plate. It is characterized by simple structure, small size, light weight and easy operation.

[0003] The existing signal butterfly valve {as shown in the publication (announcement) number: CN203286115U, a handle-type signal butterfly valve}, uses a handle (i.e., a component that drives the valve stem to rotate) structure to stabilize the opening and closing degree, but the handle structure generally only has the function of convenient retention and adjustment, and also has the disadvantage of low functional utilization.

[0020] like Figure 1~2 As shown, the utility model proposes: a fire signal quick prompt butterfly valve, comprising a valve body 1, a valve stem 2 (such as Figure 2 As shown, the valve stem 2 rotates around its shaft, which can drive the butterfly plate in the valve body 1 to rotate and open and close);

[0021] A housing 3 fixedly mounted on the valve body 1 (as shown in the figure, fixedly mounted on the top of the valve body 1, and the valve stem 2 is partially built into the housing 3 and passes through the top, and bearings and other components can be used for support during the penetration);

[0022] A driving assembly 4 connected to the valve stem 2 and rotating therewith, and a signaling assembly arranged on the housing 3, wherein the driving assembly 4 is provided with a spring pressing end;

[0023] The signal transmission component includes a pressure sensor 6 and a control component 5 for processing and transmitting the information sensed by the pressure sensor 6, and is used to process and transmit the information sensed by the pressure sensor 6, etc.;

[0024] It also includes a fixing member 7 fixedly mounted on the housing 3 for fixing the pressure sensor 6 and used for connecting and fixing the position of the pressure sensor 6;

[0025] A pressing rod 8 fixed to the elastic end of the driving component 4 and pressed against the sensing end of the pressure sensor 6, that is, the elastic end of the driving component 4 applies elastic pressure to the pressing rod 8, thereby pressing against the sensing end of the pressure sensor 6;

[0026] and a plurality of through holes 9 provided on the housing 3, in which a portion of the pressing rod 8 moves (as shown in the figure, a plurality of through holes 9 are provided, and when the pressing rod 8 is placed in the through hole 9, it indicates the opening and closing indication when the driving component 4 drives the valve stem 2 to operate, which can provide an intuitive signal effect, understand the opening and closing conditions, and has a good quick prompting effect);

[0027] like Figure 2 As shown, the control component 5 includes a microcontroller (the microcontroller can be an LPC820 microcontroller or an LPC840 microcontroller, etc.) and a wireless transceiver module (the model of the wireless transceiver module is: NRF24L01, etc.) fixed in the housing 3. The microcontroller is electrically connected to the wireless transceiver module and the pressure sensor 6 respectively {also includes a power line to connect to an external power supply to power the electrical components (microcontroller, etc.)};

[0028] The wireless transceiver module is connected to the control device at the use location (the control device is: smart phone cloud platform and user terminal, etc.), and the power line is connected to the external power supply. After the pressure sensor 6 senses the pressure, the information is transmitted to the microcontroller for information processing, and then the wireless transceiver module is used to send the information to understand whether the butterfly valve is open or closed;

[0029] According to the above, the position of the through hole 9 is set to correspond to the opening and closing of the valve stem 2 when the driving component 4 drives the valve stem 2 to operate (such as Figure 1 As shown, the through holes 9 are provided with multiple groups and are evenly distributed on the housing 3 in an arc shape on the coaxial line of the valve stem 2, that is, multiple groups of annular holes are evenly distributed on the housing 3, each corresponding to a different angle of opening and closing, and the first two corresponding to the use positions of opening and closing;

[0030] like Figure 2As shown, the signal transmission component is arranged in the shell 3, that is, the pressure sensor 6 and the control component 5 are both arranged inside the shell 3, with good protection; at the same time, the through hole 9 connects the inside and outside of the shell 3 to ensure that the pressure rod 8 contacts the pressure sensor 6.

[0031] In order to realize the implementation and use of the above-mentioned drive assembly 4, it is proposed that Figure 2 As shown, the specific structure and composition of the driving assembly 4 can be as follows: the driving assembly 4 includes an upper pressure rod 41 with one rod end fixed to the top of the valve stem 2, a lower pressure rod 42 at the lower end of the upper pressure rod 41 (the lower end of the lower pressure rod 42 is the spring-pressing end of the driving assembly 4), a rotating member 43 for connecting between the two rod ends of the upper pressure rod 41 and one rod end of the lower pressure rod 42, and a spring 44 fixedly installed between the upper pressure rod 41 and the lower pressure rod 42 for elastic support, and the outer side of the lower pressure rod 42 is fixed to the pressure rod 8;

[0032] The structure of the drive assembly 4 is as follows: Figure 2 As shown, the right end of the upper pressure rod 41 is fixed (the fixation can be screw connection, etc.) to the top of the valve stem 2, and the upper pressure rod 41 is rotatably connected to the right end of the lower pressure rod 42 through a rotating member 43 (the rotating member 43 can be a hinge, a rotating shaft, etc.). At the same time, a spring 44 is connected between the upper pressure rod 41 and the lower pressure rod 42 to provide elastic support, which is the rotational elastic support generated by the lower pressure rod 42 at the rotating member 43, and generates an elastic force on the pressure rod 8 toward the pressure sensor 6.

[0033] The fixing member 7 is a spring hinge (such as Figure 2 As shown, the pressure sensor 6 is installed inside the housing 3 through a spring hinge. The pressure sensor 6 is elastically supported counterclockwise at the spring hinge. When the pressure sensor 6 is pressed to the right by the pressure rod 8, excessive rigidity can be prevented, thereby protecting the pressure sensor 6).

[0034] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0035] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0036] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
