Detailed description of the invention
Fig. 1 is the structural schematic diagram of the novel valve in embodiment 1 with automatic blowout device;
Fig. 2 is the structural schematic diagram of the novel spray gun in embodiment 2 with automatic blowout device.
Specific embodiment
As shown in Figure 1, embodiment 1 discloses a kind of novel valve with automatic blowout device, including conveyance conduit 11, valve Door 12, non-return valve 13, purging pipeline 14, regulating valve 15, electromagnetic flowmeter 16, pressure transmitter 17.It can be with by regulating valve 15 Control the uninterrupted in purging source.Medium can be prevented to enter in purging source from purging pipeline when maloperation by non-return valve 13.Electricity Magnetic flowmeter 16 and pressure transmitter 17 may determine that by whether purging pipeline blocks.
Purging pipeline 14 is connect by material position flange with conveyance conduit 11, the gas source for purging be drying compressed air, Water etc. can specifically be determined according to pumped (conveying) medium.It purges pipeline 14 and uses stainless steel or carbon steel piping, diameter can be according to work Condition is rationally designed.
Existing compressed air or water etc. in device can be used in purging source, is connected to drying compressed air by purging pipeline 14 Or water etc..Regulating valve 15 passes through the control system of cable connection integrated system, is opened by the DCS timing control of existing integrated system Degree is realized regulating valve 15 at interval of certain time and is automatically turned on, and is blown purging pipeline 14 to 12 position of valve, every time The time of blowing can also be realized by DCS timing control and be set.Electricity can be passed through by electromagnetic flowmeter 16 and pressure transmitter 17 Cable connects the control system of integrated system, and whether monitoring is blocked by purging pipeline or pipeline.
Realized by the blow device and regular purge carried out to the flyash of valve adherency, it is ensured that valve or spray gun eventually at In normal working condition;Also, the blow device is realized using the existing drying compressed air of system itself or water etc. Low cost.The case where so as to avoid causing pumped (conveying) medium that cannot normally convey due to valve blockage, so that raw Efficiency is produced to improve.
