Abstract
The utility model discloses a pneumatic diaphragm control valve checking and emergency pipeline of a shred manufacturing workshop of a tobacco factory. The pneumatic diaphragm control valve checking and emergency pipeline comprises a pneumatic diaphragm control valve and an emergency pipeline. An inlet of the pneumatic diaphragm control valve is connected with a control end of an electric valve positioner by a first check valve, an inlet of the electric valve positioner is connected with a stop valve, an inlet of the emergency pipeline is connected with a second outlet of a three-way valve, a first outlet of the three-way valve is connected with an inlet of the stop valve, the second outlet of the three-way valve is connected with a filter pressure reducing valve by a manual valve pipe, a filter pressure reducing valve pipe is connected with a low-pressure reducing valve, and the low-pressure reducing valve is connected with the inlet of the pneumatic diaphragm control valve by a second check valve. The pneumatic diaphragm control valve checking and emergency pipeline has the advantages that the pneumatic diaphragm control valve checking and emergency pipeline can normally run by the aid of the emergency pipeline, failure conditions of pipelines of the pneumatic diaphragm control valve can be detected, and accordingly the work efficiency can be improved.
Description
Technical field
The utility model relates to cigarette factory throwing workshop appliance technical field, relates in particular to a kind of for the inspection of cigarette factory throwing workshop pneumatic diaphragm control valve and emergency line.
Background technique
Pneumatic diaphragm control valve is taking pressurized air as power source, taking cylinder as final controlling element, and removes to drive valve by means of electropneumatic valve positioner annexes such as () transducer, solenoid valve, guarantor position valves and control program, realizes switching value or proportion expression and regulates.Complete adjutage track media by the control signal that receives industrial automation control system, thereby realize industrial desired: the various process parameters such as moisture, flow, pressure, temperature.Throwing workshop pneumatic diaphragm control valve belongs to a kind of control valve on throwing equipment, is mainly used in the steam flow control in workshop.In the high temperature of real work, high humidity environment, be prone to out-of-control phenomenon for relatively fragile pneumatic diaphragm control valve.If there is out-of-control phenomenon in pneumatic diaphragm control valve, will be directed at the various process parameters such as moisture, flow, pressure, temperature, do not reach standard.Pneumatic diaphragm control valve can not be processed maintenance in time if there is problem, will affect this procedure and next process quality of product.
Model utility content
The purpose of this utility model is to provide the pneumatic diaphragm control valve inspection of a kind of cigarette factory's throwing workshop and emergency line, can effectively detect pneumatic diaphragm control valve failure condition, and can the in the situation that of pneumatic diaphragm control valve fault, start emergency line, reduce device maintenance and maintenance time, greatly increased work efficiency.
The technical solution adopted in the utility model is:
The pneumatic diaphragm control valve inspection of a kind of cigarette factory's throwing workshop and emergency line, comprise pneumatic diaphragm control valve, the import of pneumatic diaphragm control valve connects the control end of electropneumatic valve positioner by the first safety check, the import of electropneumatic valve positioner connects stop valve, also comprise emergency line, the second outlet of the import connecting tee valve of emergency line, the first outlet of triple valve connects the import of stop valve, the second outlet of triple valve connects filtering pressure reducing valve by manually operated valve pipe, filtering pressure reducing valve pipe connects low-pressure relief valve, low-pressure relief valve connects the import of pneumatic diaphragm control valve by the second safety check.
The utility model utilizes emergency line as detecting and spare duct, emergency line comprises manually operated valve, filtering pressure reducing valve, low-pressure relief valve and the second safety check successively, in the time that pneumatic diaphragm control valve pipeline breaks down, open in time emergency line, can either normally move, can also detect pneumatic diaphragm control valve circuit failure situation, increase work efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises pneumatic diaphragm control valve 3, the import of pneumatic diaphragm control valve 3 connects the control end of electropneumatic valve positioner 2 by the first safety check 7, the entrance point of electropneumatic valve positioner 2 is by the first outlet of stop valve 1 connecting tee valve 9, also comprise emergency line, the second outlet of the import connecting tee valve 9 of emergency line, the second outlet of triple valve 9 connects filtering pressure reducing valve 5 by manually operated valve 4 pipes, filtering pressure reducing valve 5 pipes connect low-pressure relief valve 6, and low-pressure relief valve 6 connects the import of pneumatic diaphragm control valve 3 by the second safety check 8.
The utility model, in the time of normal use, is first closed manually operated valve 4 valves, makes emergency line in state of dormancy, and stop valve 1 is opened, and in folding condition, now, pneumatic diaphragm control valve 3 pipelines are normally worked; In the time that pneumatic diaphragm control valve 3 pipelines break down, stop valve 1 is closed, pneumatic diaphragm control valve 3 pipelines quit work, now, staff opens manually operated valve 4, emergency line startup work, first filtering pressure reducing valve 5 is generally regulated, what regulate is the opening degree of pneumatic diaphragm control valve 3 flows, again low-pressure relief valve 6 is regulated, this time regulate and belong to fine setting, make pneumatic diaphragm control valve 3 accurately reach the flow value of need of production, after adjusting, emergency line is normally worked; In the time regulating filtering pressure reducing valve 5 and low-pressure relief valve 6, when pneumatic diaphragm control valve 3 is not had to corresponding action executing, staff can judge that now pneumatic diaphragm control valve 3 breaks down, and need to keep in repair; When adjusting work complete, when emergency line and pneumatic diaphragm control valve 3 normal work, illustrate that pneumatic diaphragm control valve 3 does not have fault on the one hand, emergency line is normally worked on the other hand, do not affect the normal operation of follow-up work, provide reliable operational support for producing, now, can judge that electropneumatic valve positioner 2 breaks down, and need to keep in repair; This kind of judgement aspect, can make staff judge fast which device in pneumatic diaphragm control valve 3 pipelines and break down, and greatly saves the time of staff's looking up the fault, does not affect again the normal operation of equipment simultaneously.
