Description

Technical Field

[0001] This utility model relates to a fireproof damper regulating valve function detector for fire protection systems. Background Technology

[0002] There are no dedicated testing tools for the existing fireproof damper regulating valves. During the testing process, the valve rotation positioning card's notched positioning bolt is released when pressed down, resulting in low operating efficiency and a risk of mechanical rebound. Summary of the Invention

[0003] This utility model provides a functional detector for a fireproof damper regulating valve. Its features include: a movable hammer 1 at one upper end, an upper telescopic handle 2 at the other upper end, an operation positioning bayonet 3 at one lower end, a lower telescopic handle 4 at the other lower end, and a support 5 in the middle. The upper and lower parts of the detector are connected by a rotating shaft 6 of the support 5. The impact surface 7 of the movable hammer 1 is slightly concave and arc-shaped. The movable hammer 1 itself is threaded and equipped with an adjusting nut 8 and a locking nut 9. Adjusting the adjusting nut 8 and the locking nut 9 allows the movable hammer 1 to be in the optimal operating position. The slightly concave and arc-shaped impact surface 7 of the movable hammer 1 facilitates convenient and effective positioning and pressing tests on the temperature sensor positioning bolt 10 of the fireproof damper regulating valve. The operation positioning bayonet 3 serves to lock and position the circular base 11 of the temperature sensor positioning bolt 10 of the fireproof damper regulating valve during testing. When the upper telescopic handle 2 and the lower telescopic handle 4 are properly extended, they facilitate labor-saving operation and prevent injury to the operator's hands from rebounding when the fireproof damper regulating valve is released. Operation process: The positioning latch 3 engages the circular base 11 of the temperature sensor positioning bolt 10 of the fire damper regulating valve. The impact surface 7 of the movable hammer 1 is naturally aligned with the top of the temperature sensor positioning bolt 10. By raising the upper telescopic handle 2 and fixing the lower telescopic handle 4, the temperature sensor positioning bolt 10 is easily pressed down and released, simulating the release of the fire damper regulating valve during a fire. In terms of design, the slightly arc-shaped concave shape of the impact surface 7 of the movable hammer 1 ensures that it does not affect the release process of the temperature sensor positioning bolt 10 after it is pressed down.

[0004] This invention enables convenient, effective, and safe testing of the function of fireproof damper regulating valves. Attached Figure Description

[0009] Example 1: See Figure 1 , Figure 2 , Figure 3 and Figure 4 A functional detector for a fireproof damper regulating valve is disclosed. The detector has a movable hammer 1 at one upper end and an upper telescopic handle 2 at the other upper end. An operation positioning bayonet 3 is located at one lower end of the detector, and a lower telescopic handle 4 is located at the other lower end. A support 5 is located in the middle. The upper and lower parts of the detector are connected by a rotating shaft 6 of the support 5. The impact surface 7 of the movable hammer 1 is slightly arc-shaped and concave. The movable hammer 1 itself is threaded and equipped with an adjusting nut 8 and a locking nut 9. The entire device is made of steel. The following tests are performed on the fireproof damper regulating valve using this detector:

[0010] When the fireproof damper regulating valve is in the released state ( Figure 2 ), Move the handle 15 of the fireproof damper regulating valve in the direction of the arrow. The positioning card 14 of the fireproof damper regulating valve passes through its guide slope 13 and presses down the elastic temperature sensor positioning bolt 10 of the fireproof damper regulating valve, so that the notch 12 of the positioning card 14 locks into the temperature sensor positioning bolt 10, forming a fireproof detection state. Figure 3 When performing functional testing during a simulated fire: see... Figure 1 , Figure 4 The fireproof damper regulating valve is tested using a fireproof damper regulating valve function detector. Figure 4 The operation is as shown. During testing, the operating positioning bayonet 3 of the fireproof damper regulating valve function detector is engaged with the circular base 11 of the temperature sensor positioning bolt 10 of the fireproof damper regulating valve. The impact surface 7 of the movable hammer 1 is naturally aligned with the top of the temperature sensor positioning bolt 10 of the fireproof damper regulating valve. By raising the upper telescopic handle 2 and fixing the lower telescopic handle 4, the impact surface 7 of the movable hammer 1 presses down the elastic temperature sensor positioning bolt 10. After the temperature sensor positioning bolt 10 is pressed down, the fireproof damper regulating valve releases its own energy storage spring force, causing the fireproof damper regulating valve to switch to [position]. Figure 2 The release state is shown. After completing the functional test, manually determine whether the tested fire-resistant regulating valve is functioning correctly and effectively.
