Description
Technical field
The present invention relates to a kind of band to leak outside the membrane pump with pneumatic drive of warning, shutdown device.
Background technique
Membrane pump with pneumatic drive is a kind of novel liquid material transfer equipment, the use of the equipment such as alternative submersible pump, pollution discharge pump, centrifugal pump.Little for volume, lightweight, the easy to install feature such as flexibly of this pump.Because it can carry solids-laden fluid, there is not the advantages such as the problem of explosion-proof aspect, generally use in the increasing industry such as petrochemical industry, coating, boats and ships, water treatment, food, papermaking, mine.
Because membrane pump with pneumatic drive carries to complete fluid by the bidirectional-movement of diaphragm of rubber sheet, and can the liquid of conveyor belt particulate matter, therefore rubber membrane sector-meeting causes leaking outside of carried liquid because of reasons such as the abrasion of particulate matter and ageing of rubbers, give produce, life brings unnecessary loss.If conveying is poisonous and harmful substances, more can gives operator, bring irremediable infringement to environment.
Summary of the invention
Because prior art also exists the problems referred to above, the present invention proposes a kind of band and to leak outside the membrane pump with pneumatic drive of warning, shutdown device, can Timeliness coverage arrestment work when the elastomer diaphragm that its object is in membrane pump with pneumatic drive breaks.
The present invention solves the problem by the following technical programs:
A kind of band leaks outside the membrane pump with pneumatic drive of warning, shutdown device, it comprises upper cover, lower cover, the left intermediate module being located at the left column between described upper cover and lower cover, right column and be located between described left column and right column and right intermediate module, work chamber is formed between described left intermediate module and right intermediate module, also comprise: a primary diaphragm, it is located in described work chamber, and this primary diaphragm is fixed on described right intermediate module by a transition contiguous block; One secondary diaphragm, it is located in described work chamber, and described secondary diaphragm is fixed on described transition contiguous block by protecting block outside one, forms airtight chamber between described secondary diaphragm and primary diaphragm; One piston apparatus, it comprises the piston cylinder that piston and a top are provided with metalwork, described piston apparatus connects described airtight chamber by tracheae, and when the increase of described airtight chamber internal pressure, described piston upwards is until close to described metalwork to setting range; One system control office, described system control office connects and controls the solenoid valve that an emergency alarm and controls source of the gas, described system control office connects described piston apparatus, when described piston close to metalwork to setting range time, described system control office control described emergency alarm work simultaneously described system control office control described closed electromagnetic valve source of the gas.
Be provided with a proximity switch outside described piston cylinder, this proximity switch connects described system control office after described piston is close to metalwork to setting range.
Band of the present invention leak outside warning, shutdown device membrane pump with pneumatic drive add a diaphragm; by arranging airtight chamber between diaphragm; and promote piston movement by the pressure increased in airtight chamber; thus alarm in triggering system control room and solenoid valve; equipment of can thoroughly having stopped leaks because diaphragm damages; non-Timeliness coverage and damnous may, and can precise positioning problem device, protection personnel, enterprise, environment etc.It is that the equipment not installing this device additional cannot be mentioned in the same breath to the advantage that enterprise, society, environment bring, and has superior social reality meaning.

Embodiment
Below in conjunction with embodiment, describe the present invention in detail.
Shown in Fig. 1 and Fig. 2, Fig. 1 is the structural representation of one embodiment of the invention.Fig. 2 is the structural representation of piston apparatus of the present invention.
The band of the present embodiment leaks outside the membrane pump with pneumatic drive of warning, shutdown device, it comprises upper cover 1, lower cover 2, be located at the left column 3 between described upper cover and lower cover, right column 4 and the left intermediate module 5 be located between described left column 3 and right column 4 and right intermediate module 6, between described left intermediate module and right intermediate module, form work chamber.This membrane pump with pneumatic drive also comprises: primary diaphragm 7, secondary diaphragm 9, piston apparatus, system control office, an emergency alarm and control the solenoid valve of source of the gas.Wherein:
Primary diaphragm 7 is located in described work chamber, and this primary diaphragm 7 is fixed on described right intermediate module by a transition contiguous block 8.
Secondary diaphragm 9, it is located in described work chamber, and described secondary diaphragm 9 is fixed on described transition contiguous block 8 by protecting block 10 outside one.Airtight chamber Q is formed between described secondary diaphragm and primary diaphragm.
Piston apparatus comprises the piston cylinder 12 that piston 11 and a top are provided with metalwork.Described piston apparatus connects described airtight chamber Q by tracheae 13.When the increase of described airtight chamber Q internal pressure, described piston upwards until close to described metalwork to setting range to produce an electrical signal of reaction.Be provided with a proximity switch 14 outside described piston cylinder, this proximity switch connects described system control office after described piston is close to metalwork to setting range.
Described system control office connects and controls the solenoid valve that an emergency alarm and controls source of the gas, described system control office connects described piston apparatus, when described piston close to metalwork to setting range time, described system control office controls described system control office while that described emergency alarm starting to report to the police and controls described closed electromagnetic valve source of the gas, make whole equipment stop motion, be convenient to staff change, repair facility, more can avoid causing due to the damage of equipment the damage of personnel, goods and materials and environment.
When normally working, airtight chamber together moves with elastomer diaphragm, and because airtight chamber does not have pressure to produce, therefore piston does not outwards promote, and proximity switch can not do action.And after elastomer diaphragm breaks, liquid medium in pipeline enters airtight chamber by rupture of diaphragm place, its internal pressure is increased, and promote the piston being in bottom, after piston advances forward to the preset range of the distance metalwork of piston tip, proximity switch connects warning light and the alarm bell of system control office, meanwhile, the solenoid valve of the control membrane pump with pneumatic drive gas inlet passages be attached thereto receives electrical signal and cuts out gas channel, makes whole equipment out of service.
Should be understood that these mode of executions are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
