Technical field

It the utility model is related to a kind of dry and cold machine, more particularly to a kind of paper grade (stock) with multicircuit time water trap is cold dry Machine.

Background technology

Existing large-scale paper machine is with being typically provided with some drain valves, each drain valve on air compression system cooling driers Controlled by a 220VAC electronic timers, when the electronic timer is used to set interval between discharges and the draining of water trap Between.However, existing electronic timer and drain valve are usually all integrated installation, in water trap draining, electronic timer is easy Water inlet, causes circuit board short circuit and damages, and then causes water trap high failure rate, short life.And dredged in progress drain valve stifled Regular maintenance when, since electronic timer and drain valve connect together, make the regular maintenance of electronic timer extremely not Just.

Utility model content

Based on this, it is necessary to for deficiency of the prior art, there is provided a kind of paper grade (stock) with multicircuit time water trap Cooling driers.

A kind of paper grade (stock) cooling driers with multicircuit time water trap, including some water traps and a timer, the row Hydrophone is installed in the drain valve on drainpipe including a drainpipe and one, and some drain valves are all connected to the timer On, the timer controls the open and close of multiple drain valves at the same time；The drain valve includes valve body, coil and terminal box, The valve body is installed on the drainpipe, and the coil is installed on the valve body, and coil is connected on the timer；Institute State terminal box to be installed on the coil, terminal box is connected on external power supply.

Further, a power supply air switch is further included, the timer is connected on the power supply air switch.

Further, some controlling switches are further included, each controlling switch controls the open and close of a drain valve.

Further, the timer is equipped with a switching switch, and the switching switch exists the control model of drain valve Switched between controlling switch control and Timer Controlling.

Further, a shut-off valve is further included on the drain valve, the shut-off valve is arranged on valve body.

In conclusion in conclusion the utility model by set a timer multichannel drain valve is controlled so that Without being respectively mounted timer in each drain valve, substantial amounts of timer spare part is saved, and causes the daily of drain valve to dredge stifled work Make also extremely convenient.In addition, greatly reducing the failure rate of cooling driers, cooling driers operation is set more to stablize；Meanwhile make cooling driers Repair and maintaining also make moderate progress, drain valve troubleshooting is convenient.

Brief description of the drawings

Fig. 1 is the block schematic illustration of the embodiment for the paper grade (stock) cooling driers that the utility model has multicircuit time water trap.

Fig. 2 is the structure diagram of drain valve.

Embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, is further elaborated the utility model.

As depicted in figs. 1 and 2, the utility model provides a kind of paper grade (stock) cooling driers with multicircuit time water trap, institute Stating the paper grade (stock) cooling driers with multicircuit time water trap includes some 10 and one timers 20 of water trap, and the water trap 10 wraps Include a drainpipe 11 and one be installed in drain valve 12 on drainpipe 11, some drain valves 12 are all connected to the timer On 20, the timer 20 controls the open and close of multiple drain valves 12 at the same time.

The drain valve 12 includes valve body 13, spool (not shown), shut-off valve 14, coil 15 and terminal box 16, the valve Body 13 is equipped with a water inlet end and a water outlet, and the water inlet end is connected on the drainpipe 11.The water inlet of the valve body 14 End outside is equipped with screw thread, in order to the disassembling, assembling and replacing of drain valve 12.The shut-off valve 14 and coil 15 are assembled on the valve body On 13, shut-off valve 14 is arranged at the front side of the spool, so that when the exception of drain valve 12 cannot close, the shut-off valve 14 can The current entered from drainpipe 11 in valve body 13 are ended, and easy to the maintenance of drain valve 12.The terminal box 16 is installed in institute State on coil 15, the coil 15 is connected with the timer 20, and the terminal box 16 is connected with external power supply.

The timer 20 is used for water discharge time and the draining stand-by period for setting drain valve 12, when timer 20 is by setting Between timing output drain valve 12 act pulse, make 0 contact of timer 2 be attracted, driving drain valve 12 act draining, realize draining The function of 12 fixed time interval draining of valve.In the present embodiment, a timer 20 can drive five drain valves 12 at the same time, it is possible to understand that Ground, in other embodiments, the timer 20 can also drive more drain valves 12 according to demand.The drain valve 12 has Have and control and automatically control both of which manually, be additionally provided with the timer for drain valve 12 in manual control and automatic control The switching key switched between system.

The paper grade (stock) cooling driers with multicircuit time water trap are additionally provided with some controlling switches, each control The unlatching and opening and closing of switch one drain valve 12 of control, the controlling switch are connected on the timer 20.When timer 20 is cut When changing to MANUAL CONTROL mode, the controlling switch control drain valve 12 can be manually operated, consequently facilitating checking drain valve Whether 12 have blocking exception.When timer 20 is switched to MANUAL CONTROL mode, timer drives drain valve according to setting time 12 action drainings, without human intervention.

A power control cabinet is further included on the paper grade (stock) cooling driers with multicircuit time water trap and is installed in power control cabinet Power supply air switch 30 and, the timer 20 and drain valve 12 are electrically connected on the power supply air switch 30, institute Reliably protecting can be carried out to the circuit of timer 20 and drain valve 12 at the same time by stating power supply air switch 30.The timer 20 and control Switch processed may be contained within the power control cabinet, and the power control cabinet carries out timer 20, power supply air switch 30 and controlling switch Protection.

In conclusion the utility model is controlled multichannel drain valve 12 by one timer 20 of setting, without Timer 20 is installed in each drain valve 12, saves substantial amounts of 0 spare part of timer 2 so that the daily of drain valve 12 dredges stifled work Make extremely convenient.And the failure rate of cooling driers is greatly reduced, cooling driers operation is more stablized；Meanwhile make the dimension of cooling driers Environment is repaiied also to make moderate progress.The utility model has the advantages of simple structure, highly practical, has stronger dissemination.In addition, this practicality A coil and a terminal box only need to be installed on drain valve 12 in new, so that the troubleshooting of drain valve 12 is more square Just, while repair and maintaining can be improved, reduce failure rate, cooling driers operation is more stablized.

Embodiment described above only expresses a kind of embodiment of the utility model, its description is more specific and detailed, But it should not be interpreted as limiting the scope of the present invention.It should be pointed out that for the common of this area For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to In the scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
