(2) background technology
Now batch of 20 bulb sprinkler head ropes are put on put into bath of liquid case during detection bulb sprinkler head static state operating temperature, in case, liquid heats up with schedule speed, in order to detect sprinkler tip minimum movements temperature, action percent before set point of temperature, the highest operating temperature, will manual observation record shower nozzle action number at each temperature during detection, due to the time, temperature is in change, and glass bead can make liquid muddy after breaking, so accurately will judge in 20 shower nozzles that being carved with which shower nozzle action when a certain temperature is very difficult, and waste time and energy, its accuracy in detection and efficiency are not high yet, very inconvenience.
(3) summary of the invention
The present invention is in order to make up the defect of prior art, provide one can realize 20 bulb sprinkler heads and detect simultaneously, and automatically record the test unit of every shower nozzle action at what temperature, this device detects while also can testing multiple batches of bulb sprinkler head, and accuracy in detection and efficiency are greatly improved.
The present invention is achieved through the following technical solutions:
The static operating temperature test unit of a kind of test sprinkler tip, comprise shower nozzle mounting portion, actuating signal hop and PLC control section, it is characterized in that: described shower nozzle mounting portion comprises chassis and concentric locking collar, concentric locking collar upper end is vertically fixed with bulb sprinkler head, concentric locking collar is provided with wire guide, bulb sprinkler head action monitoring wire passes from wire guide, wire guide sealant sealing, single shower nozzle action monitoring wire in each batch collects in a wire socket, when detecting if any multiple batches simultaneously, each detection batch action wire converges and combines insert row and be connected with connecing soon, connect combination insert row to be soon connected with computer PLC by cable.
Wherein:
Described chassis and concentric locking collar are connected as a single entity by set bolt, concentric locking collar is provided with internal thread, internal thread coordinates with the outer silk of shower nozzle to be fixed vertical for bulb sprinkler head, concentric locking collar is provided with inner sleeve, shifting axle and O-ring seal are housed in inner sleeve, wherein be provided with water proof switch and Compress Spring with shifting axle axial contact, water proof switch is fixed by sealing nut and sealing gasket.
A batch of described shower nozzle is only fixed on a chassis, and its every glass bead aproll shower nozzle is respectively equipped with a batch sequence number, and the two ends on chassis are provided with supporting leg, and different chassis arranges Mission Number respectively.
The present invention ought hear that computer PLC sends buzzer and can stop screwing when screwing glass bead aproll shower nozzle, because glass bead aproll shower nozzle release cone oppresses shifting axle, shifting axle is made to oppress Compress Spring, shifting axle moves down thus presses water proof switch and makes the Continuity signal of water proof switch be transferred to computer PLC, after on-test, computer PLC is according to the heating rate of programming Control bath of liquid case and temperature retention time, temperature sensing glass ball body on glass bead aproll shower nozzle finally bursts due to expanded by heating, the explosion of temperature sensing glass ball body makes release cone lose resistance instantaneously, under release cone, cone flicks by the shifting axle of aspect, thus water proof switch is disconnected, computer PLC monitor signal disconnect after can record automatically, now namely think that temperature sensing glass ball thermometer body there occurs action, and automatically calculate this batch of how many bulb sprinkler heads action at what temperature according to programming, calculate action sample percentage and maximum temperature action number before certain temperature.
The invention has the beneficial effects as follows: structure is simple, easy to use; What realize 20 bulb sprinkler heads every action at temperature automatically to detect and record, automatically action sample percentage and maximum temperature action number before certain temperature is calculated, also can detect by multiple batches of bulb sprinkler head simultaneously, Detection job and efficiency are improved.
