Abstract

A kind of steam drying machine one vapour dual-purpose electric valve positioner, it is mainly by button, and miniature relay and pressure switch form. Respectively two dryers are carried out and not only independently controlled but also the pattern of cooperation. When the work of main vapour pushbutton enable, after main steam is first used by A machine by waste heat again after steam-water separator drainage net gas be sent to steam secondary duct (Second Automobile Works's pipeline); In the time that the pressure of Second Automobile Works's pipeline is increased to set definite value, pressure switch is automatically transformed to the main vapour of B dryer and uses Second Automobile Works. When A machine stops heating while cutting out vapour source, B machine recovers to use again main vapour automatically. Two co-operations at this point, but do not fix dividing of A, B, which platform is first started shooting, is not started shooting or start simultaneously does not affect automatic conversion; Operation freely, easy and simple to handle, and energy-efficient again.

Description

Steam drying machine one vapour dual-purpose electric valve positioner

One, affiliated technical field

A kind of circuit controller under the present invention more precisely, is that a kind of steam drying machine is carried out a vapourDual-purpose Semi-automatic control system.

Two, background technology

Utilize the heat exchange of steam to toast object, be widely used in all conglomeraties. Especially spinKnit articles of dress just more general. After spinning dyeing, need to dry, after clothes washing, also need to dry, butThat controls waste of steam only has a kind of product of drain valve. Although design in recent years changes to some extent, andStill cannot change its specific environment for use of working medium institute, so waste rate is still in 20% left and right.In conjunction with the severe situation of current energy-saving and emission-reduction, make full use of the energy, protection of the environment, enforcement of the present invention againJust there is earth shaking realistic meaning.

Three, summary of the invention

Object of the present invention, is to provide a kind of circuit controller, and it is applicable to steam drying machine one vapour twoWith the semiautomatic control in running.

In order to reach above-mentioned object, the scheme that the present invention takes is: a kind of semi-automatic circuit controller,It mainly contains button, relay and pressure switch composition. When main vapour pushbutton enable work, main steam firstAfter being used by A machine, its waste heat process steam-water separator drainage, then be sent to secondary duct (Second Automobile Works's pipeline),In the time that the pressure of Second Automobile Works's pipeline is strengthened to set definite value, pressure switch is automatically by the main vapour of B platform dryerBe transformed to and use Second Automobile Works; When A machine stops heating while cutting out vapour source, B platform dryer recovers again main vapour automaticallyUse. Two associatings at this point, neither fix dividing of A, B, also do not limit its successively start; It is easy and simple to handle,Automatically conversion; Operation freely, energy-efficient.

Four, brief description of the drawings

Fig. 1 is the main body schematic diagram of this case embodiment. (note: because two groups of electrical equipment are identical, be clearly signal,Be assumed to be two groups of A, B. )

In Fig. 1: (1) main steam button, (2) valve closing power line, continue in (3) (4) (5) (6)Electrical equipment, (7) X button (flicking is closed, heavily by discharge waste heat), (8) main vapour valve power-onLine, the power line of power transmission when (9) pressure switch UNICOM, (10) Second Automobile Works valve opening power line, (11)Tail steam valve door power-on line, (12) tail steam valve door powered-down line, (13) outer box shell, (14)Multi-line socket.

Five, specific embodiments

Below in conjunction with embodiment and accompanying drawing thereof, the present invention is remake to description.

Suppose: click (1) main vapour button, (5) work, (5.3) (note: represent No. 5 relayNo. 3 contacts, lower with. ), (5.4) deenergization, (5.6) and (5.7) energising, (5.7) are sentElectricity is given (4.3) (3.3), and (4.3) power transmission is given (4.4) (3.1), (3) work, and (3.3) power transmission is given(3.2) by two No. ten Outlet line A machine main vapour valves (26) be opened (seeing accompanying drawing 2). (23) machineHeating, drying, waste heat enters (24) steam-water separator drainage, and net gas enters looped pipeline (22), when (22)Pressure increases to setting value, and pressure switch (25) is connected ten No. six line power transmissions to (4-1.1), (4-1)Work. (supposing that 23-1 machine moves), (3-1.1) is cut off power supply, (3-1) do not work, and(3-1.5) with (3-1.6) connect power transmission No. six lines main vapour valve (26-1) closed. (4-1.3) simultaneouslyEnergising (4-1.2) power transmission is given ten No. three, No. two lines, has opened respectively (27) Second Automobile Works valve, by Second Automobile WorksOffer (23-1) dryer and use, No. two line has been opened (28-1) tail steam valve door, dual-purpose by having passed throughAfter steam condensate (SC) by (29) return pipe discharged to recovery tank. Like this (23-1) dryer use vapourAutomatically obtained exchange.

Suppose that (23-1) machine is not or not the time of operation, nature (27) can not be opened, and (23) machine is coldSolidifying water is delivered to water tank discharged to return pipe (29) automatically by (24) steam-water separator.

Dry and finish to close vapour source when (23) machine, heavily press (7) button, (5) quit work, and cutThe broken working power of (4), (3), (3.5) (3.6) UNICOM, it is main that power transmission ten No. eight lines are closed (26)Steam valve; (6) work simultaneously, (28) tail steam valve is opened in (6.2) (6.3) energising again, rapidly by (23)Storage vapour in dryer is disposed to water tank, is convenient to change dried object. , go round and begin again at this point, no matter whichFirst start shooting or do not start shooting or start simultaneously for one, do not hinder each other, running is freely, easy and simple to handle, andEnergy-efficient again.
