Automatic testing device for work circle performance of valve for automatic water spraying fire extinguishing system

Abstract

The invention discloses an automatic testing device for work cycle performance of a valve for a water spraying fire extinguishing system. The device comprises an air pump, a water boosting pump, a reservoir and a valve sample. The water boosting pump is connected with the reservoir. The right side of the valve sample is connected with the water boosting pump, and the left side is connected with awater outlet pipe. Water falls into the reservoir from the water outlet of the water outlet pipe. The top end of the valve sample is connected with a valve sample cyclic action control device. The valve sample cyclic action control device is connected with a hollow shaft torque measuring motor. The hollow shaft torque measuring motor is fixed to the lower end of a vertical telescopic shaft I. A telescopic shaft motor I is fixed to a horizontal board. The horizontal board is welded to a frame. The frame is fixed on ground. An air pump is connected with a pneumoelectric rotatable joint. The pneumoelectric rotatable joint is connected with a valve sample cyclic action control device. The automatic testing device can automatically determine whether opening or closing of the valve in an experiment is flexible and whether component damage occurs, reducing artificial interference factors, improving testing automation, improving testing quality and efficiency.

Description

technical field [0001] The invention belongs to the technical field of fire protection product detection, and in particular relates to an automatic test device for the working cycle performance of a valve used in an automatic sprinkler system. Background technique [0002] Fire gate valves, butterfly valves, ball valves, globe valves, solenoid valves, signal valves, one-way valves, buried valves and other valves used in automatic sprinkler systems need to conduct spot checks for working cycle performance tests. The number of working cycles is 5000 times. There is no damage to all parts of the flexible closing. The working pressure, shape structure, driving mode and connection form of these valves are different. Now the performance test is mostly performed manually. There are labor intensity, human interference factors and detection quality in the test and low efficiency issues. Contents of the invention [0003] In order to make up for the deficiencies of the prior art, t...
