Specific embodiment

As shown in Figure 1, 2, 3, a kind of low-pressure acetylene generator, which is characterized in that including ontology 1, the setting of calcium carbide valve 2 is at this The top of calcium carbide valve 2 is arranged in 1 top of body, hopper 21, and the part that 2 lower part of calcium carbide valve is contacted with ontology 1 is sealed using sealing ring, Tapered cap support frame 22 is cylindric reinforcing bar, and in hopper 21, both ends are welded on hopper 21 for horizontal setting, taper buffer cap 23 be conical structure, and vertex is upward, and the surface in hopper 21 with 2 relative position of calcium carbide valve is arranged in, and it is inclined to form one Buffering suface, tapered cap support frame 22 are passed through from taper buffer cap 23, and taper buffer cap 23 is welded on tapered cap support frame 22, Hollow pipeline 3 is arranged on 1 top of ontology, and one end is communicated with air, is communicated inside the other end and ontology 1, hollow pipeline 3 and ontology The part of 1 contact is sealed using sealing ring, and the lower end of hollow pipeline 3, the other end setting of cut-off plate 31 is arranged in cut-off plate 31 Shaft 32, for the setting of pneumatic device 34 on 1 top of ontology, 36 one end of control stick connects pneumatic device 34, and the other end connects shaft 32, The entirety that control stick 36, shaft 32 and cut-off plate 31 form can be that axis does 90 with control stick 36 under the drive of pneumatic device 34 Degree rotation, PLC controller 35 and solenoid valve 37 are arranged on 1 top of ontology and between pneumatic device 34 and calcium carbide valve 2, and acetylene goes out Port 13 is arranged in 1 top of ontology and in the left side of hollow pipeline 3, and baroceptor 33 is arranged on 1 upper bottom surface inner wall of ontology, Baroceptor 33 and PLC controller 35 connect, and PLC controller 35 and solenoid valve 37 connect, solenoid valve 37 and pneumatic device 34 Connection.2 executing agency of calcium carbide valve is pneumatic mechanism, connect with main shaft one end of the calcium carbide valve 2, drives the calcium carbide valve 2 main shaft rotation.The pneumatic device includes cylinder 4, and cylinder 4 is parallel to the upper bottom surface setting of ontology 1, is cut with scissors with first bearing 42 It connects on ontology 1, piston rod 41 is stretched out from cylinder 4, and connecting rod 43 and control stick 36 weld, and is parallel to the upper bottom surface of ontology 1 Setting, piston rod 41 and connecting rod 43 are hinged by second bearing 44.

When low-pressure acetylene generator works, the air in ontology 1 is first emptied, water is injected in ontology 1, calcium carbide is passed through into biography Defeated device is sent to the entrance of hopper 21, and due to the buffer function of taper buffer cap 23, the calcium carbide that eminence is fallen will not directly impact The valve plate of calcium carbide valve 2 causes valve plate to damage, and valve plate will not be caused to open, of short duration leakage occurs, to calcium carbide completely into hopper 21 Later, calcium carbide valve 2 is opened, allows calcium carbide to enter in ontology 1 and is reacted with water, the bottom that cut-off plate 31 blocks hollow pipeline 3 at this time enters Mouthful, acetylene gas can not be discharged from hollow pipeline 3.In calcium carbide and water reaction process, baroceptor 33 records ontology 1 at any time The variation of middle air pressure, when air pressure reaches 0.215MPa in ontology 1, baroceptor 33 sends a signal to PLC controller 35, PLC controller 35 is extended by the piston rod 41 that solenoid valve 37 controls cylinder 4, so that connecting rod 43 is driven to rotate with an angle of 90 degrees, Control stick 36 is rotated with an angle of 90 degrees, and shaft 32 and cut-off plate 31 are rotated with an angle of 90 degrees, and the lower inlet of hollow pipeline 3 is opened, Air pressure in ontology 1 reduces, to have the function that reduce security risk.
