Embodiment Construction
[0014] In order to understand the present invention more clearly, describe the present invention in detail in conjunction with accompanying drawing and embodiment:
[0015] Such as Figure 1 to Figure 3 As shown, the device of the present invention can be used in wet systems (wet alarm valves), deluge systems (rain alarm valves), dry systems (dry alarm valves), and pre-action systems (pre-action devices) in automatic sprinkler systems. , general valves for fire protection (gate valves, butterfly valves, signal valves, ball valves, globe valves, one-way valves, etc.), hydraulic control valves (pressure reducing valves, pressure relief valves, float valves, etc.) resistance test system.
[0016] The water supply rectification system is composed of pipelines and hydraulically calculated rectification grids in the pipelines. Such as image 3 As shown, taking the 1 / 4 circular section of the rectifying grid as an example, the position of the rectifying grid partition ...

The invention relates to a multifunctional comprehensive testing device for a fire control hydraulic valve. A water supply rectification system comprises a plurality of rectification grids; the outlet of each rectification grid is connected to a pipe network system; the pipe network system is integrated by a plurality of valve testing passages; each valve testing passage consists of pipelines with different pipe diameters; each pipeline is connected in series with a plurality of control valves and a sensor; the flow and a pressure signal are sampled by the sensor, and the acquired data is displayed on a paperless recorder in a centralized way so as to realize the simultaneous acquisition and centralized display of data; and the output of a direct-current control signal or an alternated-current control signal is controlled through an intermediate relay. Multiple testing functions are realized by simple adjustment of the control valves; and the measurement accuracy is high, the working stability is high, the detection efficiency is high and the application range is wide.
Description
technical field [0001] The invention relates to fire-fighting equipment testing equipment, in particular to a multi-functional comprehensive testing device for fire-fighting hydraulic valves. Background technique [0002] The fire hydraulic valve test device is an experimental equipment used to test valve functions and other technical indicators. During the design process or before leaving the factory, the valve needs to be installed in the pipe network for testing. Under normal conditions, valve design and production units will design special test pipelines according to different valve types, and the test pipelines are close to the actual application scenarios of the valves. For different types of valves, the test pipelines need to be reset, and the detection instruments need to be adjusted separately, and for large-diameter (greater than or equal to 200mm) vertically installed valves, it is necessary to set a high installation and test position, which adds a lot of diff...
