Description

Technical Field

[0001] The invention relates to the technical field of testing devices, in particular to a switch testing device and a method for testing a fire valve. Background Art

[0002] Fire valves are an important accessory for industrial and building pipeline control. They are composed of valve body, opening and closing mechanism, and valve cover. They have a simple structure and reliable sealing. Fire valves play a vital role in fire protection systems. They are used to control the flow of fluids to ensure that in emergency situations such as fires, fire water sources can be quickly and accurately delivered to where they are needed. Switch test devices are equipment used to detect and evaluate switch performance. Common types include switch characteristic testers, multi-function switch test devices, etc. These devices can be used to measure and analyze various parameters of switches, such as opening and closing time, speed, travel, bounce, etc., to ensure the reliability and safety of switches under different working conditions.

[0003] Traditional valve detection devices may not be able to detect and provide feedback on the success or failure of the valve switching action, nor can they detect the status of the valve, such as valve structure accuracy issues; existing valve switch testing devices may only be able to test valves of specific types or sizes, which limits their scope of application.

[0015] A method for using a switch test device for a fire valve comprises the following steps:

[0016] Step 1: The staff lifts the fire valve to the clamping claw of the clamping mechanism through external equipment, and then pulls the clamping claw to clamp the fire valve through the cylinder in the clamping mechanism, and then the staff removes the external equipment; then the slider seat and the clamping claw are pulled close to the fire valve by adjusting the cylinder, and the servo motor and the linear actuator at the end of its transmission shaft are used to provide angle adjustment and clamping force for the clamping claw, so that the clamping claw can clamp the handwheel on the top of the fire valve, and then the motor drives the screw to mesh with the electromagnetic sleeve for transmission, and when the electromagnetic sleeve is energized, the two sets of first protective shells are driven to close on the outside of the valve stem of the fire valve, and at the same time, the staff controls the diversion mechanism through the control panel to prepare for heating and pressurizing the liquid required for the test;

[0017] Step 2: The fire valve is driven by the servo motor to open and close several times, so as to detect the transmission efficiency of the handwheel of the fire valve through the monitoring mechanism. Here, the adsorption ring in the monitoring mechanism is energized to make it electromagnetically adsorb the valve stem of the fire valve. The adsorption ring and the limit card block will drive the limit ring and the second photosensitive member to rotate on the first photosensitive member. The transmission efficiency of the servo motor and the clamp is determined according to the detection data, and the transmission ratio between the valve core and the handwheel of the fire valve is obtained.

[0018] Step 3: Then, the multi-axis mechanical arm drives the fixed ring, the fixed block and the connecting pipe to approach the valve port of the fire valve, and the clamping cylinder drives the fixed block to adjust the caliber of the connecting pipe according to the valve port diameter of the fire valve. Here, the electromagnetic spring is energized and controlled to shrink or stretch, so that the electromagnetic spring provides an annular limit for the connecting pipe. Since the connecting pipe is a fire pipe fabric, the connecting pipe forms a trumpet-shaped structure on one side of the fixed ring through the limiting effect of the fixing wire and the limiting ring, so that it is more suitable for the valve port diameters of fire valves of different specifications, and then the adapter mechanism is connected to the diversion mechanism;

[0019] Step 4. According to the transmission efficiency of the fire valve, a constant flow value of the control target is formulated, and then the fluid is supplied to the adapter mechanism and the fire valve through the flow guide mechanism. Then, the opening of the valve stem and the valve core of the fire valve is controlled at a certain angle through the servo motor and the clamp. Then, the flow detector on the pipeline connected by the adapter mechanism is used to test the fluid flowing through. After calculation, the servo motor is controlled through the control panel to adjust the opening of the fire valve. During the adjustment process, the monitoring mechanism can monitor the adjustment angle of the valve stem and the valve core in real time, and record the test data through the controller and the control panel.

[0020] The present invention has the following advantages: The present invention provides a switch test device and method for a fire valve through improvement, which has the following improvements compared with similar devices:

[0041] The working principle of the switch test device and method of the fire valve is as follows:

[0042] First, when using this device, first place the device in the working area, and then connect the device to an external power source to provide the device with the power required for operation;

[0043] Second, the staff lifts the fire valve 8 to the clamping claw of the clamping mechanism 7 through external equipment, and then pulls the clamping claw to clamp the fire valve 8 through the cylinder in the clamping mechanism 7, and then the staff removes the external equipment; then, after adjusting the cylinder 52 to pull the slider seat 51 and the clamping claw 54 close to the fire valve 8, the servo motor 53 and the linear actuator at the end of its transmission shaft are used to provide angle adjustment and clamping force for the clamping claw 54, so that the clamping claw 54 can clamp the top handwheel of the fire valve 8, and then the motor 61 drives the screw 62 to mesh with the electromagnetic sleeve 63 for transmission, and when the electromagnetic sleeve 63 is energized, the two groups of first protective shells 64 are driven to close on the outside of the valve stem of the fire valve 8, and at the same time, the staff controls the diversion mechanism 2 through the control panel 3 to prepare for heating and pressurizing the liquid required for the test;

[0044] Third, the fire valve 8 is driven by the servo motor 53 to open and close several times, so as to detect the transmission efficiency of the hand wheel of the fire valve 8 through the monitoring mechanism 66. Here, the adsorption ring 667 in the monitoring mechanism 66 is energized to make it electromagnetically adsorb the valve stem of the fire valve 8. The adsorption ring 667 and the limit block 666 will drive the limit ring 665 and the second light sensing member 664 to rotate on the first light sensing member 663. The transmission efficiency of the servo motor 53 and the clamp 54 is determined according to the detection data, and the transmission ratio between the valve core of the fire valve 8 and the hand wheel is obtained.

[0045] Fourth, the multi-axis mechanical arm 91 drives the fixing ring 92, the fixing block 94 and the connecting pipe 97 to approach the valve port of the fire valve 8, and the clamping cylinder 93 drives the fixing block 94 to adjust the caliber of the connecting pipe 97 according to the valve port diameter of the fire valve 8. Here, the electromagnetic spring 95 is energized and controlled to contract or extend, so that the electromagnetic spring 95 provides an annular limit for the connecting pipe 97. Since the connecting pipe 97 is a fire pipe fabric, the fixing wire 96 and the limiting ring 98 form a trumpet-shaped structure on one side of the fixing ring 92, so as to be more suitable for the valve port diameters of fire valves 8 of different specifications, and then the adapting mechanism 9 is connected to the diversion mechanism 2;

[0046] Fifth, a constant flow value of the control target is formulated according to the transmission efficiency of the fire valve 8, and then the fluid is supplied to the adapter mechanism 9 and the fire valve 8 through the flow guide mechanism 2, and then the opening of the valve stem and the valve core of the fire valve 8 is controlled at a certain angle through the servo motor 53 and the clamp 54, and then the flow detector on the pipeline connected to the adapter mechanism 9 is used to test the fluid flowing through, and a proportional threshold is established according to the data after calculation, and the servo motor 53 is controlled to adjust the opening of the fire valve 8 through the control panel 3.

The transmission ratio between the valve stem and the hand wheel of the fire valve 8 is adjusted by the monitoring mechanism 66, and then the fixed block 94 is driven by the multi-axis mechanical arm 91 and the clamping cylinder 93 to adjust the caliber of the connecting pipe 97, so that the connecting pipe 97 forms a trumpet-shaped structure on one side of the fixing ring 92, so as to be more suitable for the valve port diameter of the fire valve 8 of different specifications. Then, the opening control of the valve stem and the valve core of the fire valve 8 by the first adjustment mechanism 5 is proportional to the flow detector data on the pipeline connected to the adapter mechanism 9, and the test data is recorded under the real-time monitoring of the monitoring mechanism 66.

Step 3: Then, the fixing ring (92), the fixing block (94) and the connecting pipe (97) are driven by the multi-axis mechanical arm (91) to approach the valve port of the fire valve (8), and the fixing block (94) is driven by the clamping cylinder (93) to adjust the diameter of the connecting pipe (97) according to the valve port diameter of the fire valve (8). Here, the electromagnetic spring (95) is energized and controlled to shrink or stretch, so that the electromagnetic spring (95) provides an annular limit for the connecting pipe (97). Since the connecting pipe (97) is a fire pipe fabric, the fixing wire (96) and the limiting ring (98) form a trumpet-shaped structure on one side of the fixing ring (92), so that it is more suitable for the valve port diameters of fire valves (8) of different specifications, and then the adaption mechanism (9) is connected to the diversion mechanism (2); Step 4: According to the transmission efficiency of the fire valve (8), a constant flow value of a control target is formulated, and then the flow guide mechanism (2) supplies liquid to the adapter mechanism (9) and the fire valve (8), and then the servo motor (53) and the clamp (54) are used to control the opening of the valve stem and the valve core of the fire valve (8) at a certain angle, and then the adapter mechanism (9) is connected to the flow detector on the pipeline to test the fluid flowing through, and after calculation, the servo motor (53) is controlled to adjust the fire valve (8) through the control panel (3), and the monitoring mechanism (66) can monitor the adjustment angle of the valve stem and the valve core in real time during the adjustment process, and the test data is recorded through the controller (67) and the control panel (3).
