Description

Technical Field

[0001] This utility model relates to the field of fire signal butterfly valve technology, and in particular to a fire signal butterfly valve. Background Technology

[0002] Fire signal butterfly valves are commonly used in fire protection systems. They are primarily used to control the flow of water, air, or other media, and monitor the valve's open / closed status through signal feedback to ensure the fire protection system functions properly in emergencies. Integrating valve control and signal transmission functions, they are a crucial component of fire protection systems. Fire signal butterfly valves not only provide vital flow control but also serve as information feedback mechanisms, ensuring the efficient and reliable operation of the fire protection system.

[0003] However, existing fire signal butterfly valves are difficult to filter water and centrally treat impurities during use, causing impurities in the water flow to impact or corrode the disc, affecting the service life of the fire signal butterfly valve. Utility Model Content

[0009] As a further embodiment of this utility model, the bottom of the fixed sleeve is slidably connected with several sets of balls, and the bottom of the sliding rod is provided with a groove that matches the balls. The groove facilitates the sliding of the balls.

[0010] As a further embodiment of this utility model, an actuator is fitted onto the surface of the fixed sleeve, a rotating rod is rotatably connected to one side of the actuator, and a turntable is fixedly connected to one end of the rotating rod.

[0014] (III) Beneficial Effects

[0015] This utility model provides a fire signal butterfly valve, which has the following beneficial effects:

[0016] 1. This fire signal butterfly valve, through the design of a cleaning component, filter screen, and mesh bag, filters the passing water during use. Impurities fall into the mesh bag, while some adhering to the filter screen are rotated by the impact of the water flow. This rotation drives the rotating sleeve, which in turn drives the cleaning brushes on both sides to scrape the filter screen. After the mesh bag has accumulated impurities for a period of time, the sealing plug opens, allowing the discharge pipe to expel the internal impurities. This achieves the effect of cleaning and extending the lifespan of the filter screen, preventing clogging during use. Simultaneously, it filters the water, preventing impurities from impacting or corroding the disc, thus improving the service life of the fire signal butterfly valve.

[0017] 2. This fire signal butterfly valve, through the design of the telescopic assembly and the fixed sleeve, allows for convenient operation. Pressing the sliding rod causes it to move the limit ring, which in turn presses down on the support spring. As the sliding rod slides, the ball joint moves from the groove on the fixed sleeve to the groove at the bottom of the sliding rod, disengaging from the slot inside the socket. This facilitates easy removal of the actuator. For installation, the actuator is inserted into the socket along with the fixed sleeve. Releasing the sliding rod allows the support spring to return to its original shape, pushing the sliding rod and forcing the ball joint into the socket. This achieves convenient actuator removal and installation, facilitating maintenance or replacement and improving the overall convenience of the fire signal butterfly valve.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1 to 4This utility model provides a technical solution: a fire signal butterfly valve, including a valve body 1, with a filter screen 2 slidably connected inside the valve body 1. A cleaning component 3 is rotatably connected to the center of the filter screen 2. Through the arrangement of the cleaning component 3, the filter screen 2, and the mesh bag 4, the filter screen 2 can be cleaned and used for a long time, preventing it from becoming clogged during use. Simultaneously, it filters water, preventing impurities from impacting or corroding the disc 18, thus improving the service life of the fire signal butterfly valve. A mesh bag 4 is fixedly connected to one side of the filter screen 2. A connecting pipe 5 is fixedly connected to the top of the valve body 1, and a support platform 6 is fixedly connected to the top of the connecting pipe 5. Four sets of sockets 7 are fitted onto the top surface of the support platform 6. The sockets 7 are internally inserted... A fixed sleeve 8 is connected, and a telescopic component 9 is slidably connected inside the fixed sleeve 8. The telescopic component 9 and the fixed sleeve 8 are designed to facilitate the disassembly and assembly of the actuator 13, making it convenient for personnel to inspect or replace the actuator 13 and improving the convenience of the fire signal butterfly valve. The cleaning component 3 includes a rotating sleeve 301 rotatably connected to the center of the filter screen 2. A spiral rod 302 is sleeved inside the rotating sleeve 301, and cleaning brushes 303 are fixedly connected to both sides of the rotating sleeve 301. The telescopic component 9 includes a sliding rod 901 slidably connected inside the fixed sleeve 8. A limit ring 902 is sleeved on the surface of the sliding rod 901, and a support spring 903 is fixedly connected to the bottom of the limit ring 902.

[0025] The bottom of the net bag 4 is connected to a discharge pipe 10, and the bottom of the discharge pipe 10 is threaded with a sealing plug 11. The sealing plug 11 facilitates the discharge of impurities.

[0026] The bottom of the fixed sleeve 8 is slidably connected with several sets of balls 12, and the bottom of the sliding rod 901 is provided with a groove that matches the balls 12. The groove facilitates the sliding of the balls 12.

[0027] An actuator 13 is fitted onto the surface of a fixed sleeve 8. A rotating rod 14 is rotatably connected to one side of the actuator 13. A turntable 15 is fixedly connected to one end of the rotating rod 14. The turntable 15 drives the rotating rod 14 to rotate.

[0028] A valve stem 16 is rotatably connected inside the connecting pipe 5. An installation sleeve 17 is sleeved on the bottom of the valve stem 16. Discs 18 are fixedly connected to both sides of the installation sleeve 17. The discs 18 serve to seal the valve body 1.

[0029] A retaining ring 19 is fitted inside the valve body 1. The retaining ring 19 and the filter screen 2 are both provided with four sets of threaded holes. Bolts 20 pass through the threaded holes. The bolts 20 facilitate installation.

[0030] The discharge pipe 10 is sleeved at the bottom of the valve body 1, and the two sides of the connecting pipe 5 are fixedly connected with support rings 21. The support rings 21 facilitate transportation.

[0031] In this invention, the working steps of the device are as follows:

[0032] First step: When in use, the filter screen 2 filters the passing water flow, and the impurities fall into the net bag 4. Some of the impurities that stick to the filter screen 2 are driven by the impact of the water flow to rotate the spiral rod 302, which in turn drives the rotating sleeve 301. The rotating sleeve 301 drives the cleaning brushes 303 on both sides to scrape the filter screen 2. After the net bag 4 has accumulated for a period of time, the sealing plug 11 is opened, so that the discharge pipe 10 discharges the internal impurities.

[0033] Second step: When in use, press the sliding rod 901, so that the sliding rod 901 drives the limiting ring 902, so that the limiting ring 902 presses down the support spring 903. Then, when the sliding rod 901 slides, the ball 12 slides from the groove on the fixed sleeve 8 to the groove at the bottom of the sliding rod 901. The ball 12 disengages from the slot inside the socket 7, thus making it easy to disassemble the actuator 13.

[0034] Third step: When installation is required, the actuator 13 drives the fixed sleeve 8 into the socket 7, thereby releasing the sliding rod 901, so that the support spring 903 restores its deformation and pushes the sliding rod 901, squeezing the ball 12 into the socket 7.
