Problems solved by technology

[0002] The valve control system is widely used in airports, subway stations and other occasions to control the opening and closing of the ventilation fan and the adjustment of the opening degree. The existing fan valve is connected to the control box. The two circuits are connected. After the regulating valve is installed, it is necessary for professionals to connect the debugging equipment and the regulating valve actuator correctly before debugging. The regulating valve is generally installed at a relatively high position, and the debugging operation is extremely inconvenient. At present, there is no such The hand-held maintenance equipment can directly detect the valve control system. Operators are required to identify each functional terminal one by one and then connect the maintenance circuit, which requires a high professional level of operators; It is complicated and cumbersome to know whether it is the fault of the regulating valve or the fault of the control box

Embodiment 1

[0023] The quick maintenance device for the valve control system includes a quick junction box and a mobile handheld operator. The quick junction box is equipped with a terminal XT2 connected to the actuator of the valve control system, a terminal XT1 connected to the control box, and a mobile terminal. The terminal XT3 connected to the hand-operated terminal, also has a switching relay KA for switching the actuator signal of the valve control system between the control box and the mobile hand-held operator, and is used to connect the terminal with the mobile hand-held operator XT3 is led out by an aviation socket, refer to figure 1 As shown; the mobile handheld operator includes two power input terminals XT3: 3 and XT3: 4, power indicator light H1, valve closing signal indicator H2, valve opening signal indicator H3 and valve opening / closing operation switch; power indicator light H1 is connected between the two power input terminals, the valve closing signal indicator H2 is ...

Embodiment 2

[0031] refer to image 3 , in this embodiment, the structure of the mobile handheld operator is the same as that of Embodiment 1, and the terminals connecting the quick junction box to the actuator of the valve control system include a common terminal XT2:1, an open terminal XT2:2 and a closed terminal XT2:3, This group of terminals is connected to the corresponding terminals XT1:1, XT1:2, and XT1:3 of the control box through the step-down transformer BK and the normally closed contacts of the switching relay KA, and is used to connect the terminals XT3:6, XT3:2, XT3:1 are connected with the normally open contacts of switching relay KA; there is also a driving relay KA2 in the box, and one end of the secondary coil (AC24V) of the step-down transformer is connected to the common end XT3:1 of the actuator connection end of the valve control system The other end is connected to the open end XT3:2 of the actuator connection end of the valve control system and connected to the clos...

Embodiment 3

[0033] refer to Figure 4 , in this embodiment, the terminals connecting the quick junction box to the actuator of the valve control system include a common terminal XT2:1, an opening terminal XT2:2 and a closing terminal XT2:3, and this group of terminals passes through the normally closed contact of the switching relay KA Connect with the corresponding terminals XT1:1, XT1:2, XT1:3 of the control box, and connect the terminals XT3:6, XT3:2, XT3:1 for connecting the mobile hand operator with the normally open contacts of the switching relay.

Abstract

The invention provides a fast overhauling device for a valve control system, which comprises a fast wiring box, a movable hand holder and a switching relay. Three groups of wiring terminals respectively connected with an actuator, a controller and the movable hand holder of the valve control system are arranged in the fast wiring box. The switching relay and the wiring terminal connected with themovable hand holder are led out through an aviation socket. The movable hand holder comprises two power source input ends, a power source indicating lamp, a valve closing signal indicating lamp, an valve opening signal indicating lamp and a valve opening / closing operation switch. The wiring terminals are led out concentratedly through an aviation plug. The fast overhauling device for the valve control system has the advantages of switching signals of an adjusting valve actuator to the aviation socket, being capable of connecting signal terminal without one-by-one identification, and being easy in operation, convenient in use, firm and durable in structure and stable and reliable in working.
