Description
Technical field
The utility model relates to sentinel valve, relates in particular to a kind of sentinel valve that can carry out in-service monitoring to the working condition of self.
Background technique
Disclose a kind of sentinel valve among the Chinese patent CN85200718 " bag filters of two film sheet fast-pulse valve deashings ", this sentinel valve is not high to material and requirement on machining accuracy, and self resistance is low, opens and closes rapidly, therefore is widely used.But the working condition of this sentinel valve can only rely on hand inspection, and need have the people who enriches correlation experience and could make right judgement its working condition, work brings inconvenience to maintenance and management, main is, if its working condition of untimely adjustment, the performance of the equipment that influence is supporting with it.
A kind of sentinel valve is disclosed among the Chinese patent ZL02216088.4 " a kind of sentinel valve ", this sentinel valve adopts the mode that is installed in the displacement transducer continuous detecting main film position in the valve body to judge the fault of sentinel valve, but because of the magnetic core guide rod of displacement transducer is connected with main film, and magnetic core guide rod perpendicularity is wayward, causes magnetic core guide rod and displacement transducer endoporus serious wear even influences the keying of main film owing to frictional force is excessive.
The sentinel valve of selling on the domestic and international market of the same type is a lot, and structure is similar, sells more at present on Chinese market as the sentinel valve of the same type of Australian GOYEN company and the manufacturing of U.S. ASCO company.But all these sentinel valves all do not have the device that can carry out online detection to faults itself.Above-mentioned sentinel valve all not too rationally causes its effective actual internal area less than normal owing to the design of throttle orifice, and ability to work is on the weak side.
Summary of the invention
The purpose of this utility model be exactly for provide a kind of can be to online detection of the working condition of self and the effective big sentinel valve of actual internal area, this sentinel valve ability to work is strong and can in time adjust its working condition, timely discovery fault is also got rid of, and makes its proper functioning.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of sentinel valve, comprise pilot solenoid valve 1, loam cake 2, guide's diaphragm 3, valve body 5, air supply passage 6, winding-up pipe 7, pressure spring 10, main film 11, valve seat 13, pressurized air air storage bag 14, described air supply passage 6 is located in the valve body 5, described main film 11 is provided with through hole 12, it is characterized in that, be provided with in the described pressure spring 10 fixedly connected with valve body 5 near switch 8, in near switch 8, be provided with main film 11 on metal bolts induction and produce the vibration inductive head of eddy current, also comprise signal collection display unit 16, lead 15, described signal collection display unit 16 is passed through lead 15 and is connected near switch 8.
Described air supply passage 6 is 2% with the ratio of through hole 12 total sectional areas.
Compared with prior art, use sentinel valve of the present utility model, can in time observe the working condition of main film, in time adjusted when abnormal conditions occurring, make its proper functioning by the signal collection display unit.Wherein, directly contact with main film in the motion near switch, the two is energy reliably working all.Throttle orifice is that air supply passage 6 is more reasonable with comparing of through hole 12 sectional areas in addition, thereby makes the effective actual internal area of the utility model big, and ability to work is strong.
Description of drawings
Fig. 1 is the structural representation of the utility model sentinel valve.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of sentinel valve, comprise pilot solenoid valve 1, loam cake 2, guide's diaphragm 3, discharge channel 4, valve body 5, air supply passage 6, winding-up pipe 7, near switch 8, exhaust passage 9, pressure spring 10, main film 11, through hole 12, valve seat 13, pressurized air air storage bag 14, lead 15, signal collection display unit 16, be provided with in the described pressure spring 10 fixedly connected with valve body 5 near switch 8, in near switch 8, be provided with main film 11 on metal bolts induction and produce the vibration inductive head of eddy current, described main film 11 is provided with through hole 12, and described signal collection display unit 16 is passed through lead 15 and is connected near switch 8.Described sentinel valve, its air supply passage 6 is 2% with the ratio of through hole 12 total sectional areas.
During sentinel valve work, pilot solenoid valve 1 exhaust, then guide's diaphragm 3 top releases, thereby guide's diaphragm 3 is upwardly opened, main film 11 passes through its discharge channel 4 releases, thereby main film 11 is moved up, and the pressurized air in the pressurized air air storage bag 14 are by 7 outflows of winding-up pipe; When sentinel valve quits work, pilot solenoid valve 1 is closed, pressurized air enters the valve pocket on guide's diaphragm 3 tops and makes guide's diaphragm 3 cover exhaust passage 9 downwards by air supply passage 6, pressurized air by the through hole on the main film 11 12 enters the valve pocket on main film 11 tops and makes main film 11 cover winding-up pipe 7 downwards, when main film 11 moves up, when reaching distance of reaction near switch when metal bolts top on it and near the distance between the sensitive surface of switch 8, produce a switching value signal and show that main film 11 has been moved to the position near switch, collect signal and show its result by lead 15.Use sentinel valve of the present utility model, can in time observe the working condition of main film 11, in time got rid of when abnormal conditions occurring or adjust, make its proper functioning by signal collection display unit 16.
Test by experiment is when the utility model specification is 3 " time, its effective actual internal area is 4750mm
2Than among the Chinese patent CN85200718 " bag filters of two film sheet fast-pulse valve deashings " disclosed 3 " effective actual internal area of sentinel valve is big by 12%; than Australian GOYEN company make of the same type 3 " effective actual internal area of sentinel valve is big by 30%, than U.S. ASCO company make of the same type 3 " effective actual internal area of sentinel valve is big by 54%.
