Technical field
The present invention relates to a kind of without bottom valve water tank that may be used for intelligent control system, be applicable to have bottom valve pumping plant to transform centrifugal water pump without bottom valve device as by centrifugal.
Background technique
Many Centrifugal pump drainages using band bottom valve are still had in each large mine of China.Centrifugal pump before activation, must drain air in pump, and bottom valve is that before preventing from starting, the liquid that pours into flows out in pump, plays one-way valve, and plays when preventing termination of pumping, and in pumping intake piping, material blows back in pond and causes in inlet pipe without the effect of expecting.But bottom valve often there will be the phenomenon of damage in use, maintenance trouble, cost is high, and the Security that impact is produced.And the use of bottom valve consumes too much power, is unfavorable for energy-saving and emission-reduction.
Also occurred some bottomless valve draining devices at present, the drainage means of these types generally needs to add fluidic device, to drain the air in centrifugal pump when starting.
Summary of the invention
The object of the invention is to cancel the fluidic device used when the bottom valve of centrifugal pump and existing bottomless valve draining device start, and provide executable hardware platform for intelligent control system.
In order to achieve the above object, the present invention mainly comprises tank box part, water pipe and water pipe mounting bracket, valve class device and sensor.Wherein tank box part comprises: suction sleeve, filter, service hatch, weep hole and relevant flange in tank box, case; Valve class device comprises: gate valve, electromagnetic valve for mine and electric ball valve for mine; Sensor comprises: B/P EGR Back Pressure Transducer EGR and vacuum checking device.

Embodiment
The character of innovation of withdrawing deposit to make the present invention and using process are more easily grasped, and describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing:
As Fig. 1, shown in Fig. 2 and Fig. 3, filter (2) is connected on tank drains hole (3) place with scarf weld, port lid (5) will be keeped in repair be connected with bolt with service hatch (4), in case, suction sleeve (6) is connected with suction sleeve flange (1), B/P EGR Back Pressure Transducer EGR (10) is arranged on water tank (17) top, electric ball valve for mine (11) is arranged on valve body mounting bracket (9) with bolt Connecting format, water inlet and outlet skirt (12) is arranged on electric ball valve for mine (11) left and right sides, exhaust weldless tube (13) is welded on water tank (17), and be connected with electromagnetic valve for mine (16), electromagnetic valve for mine (16) the other end is connected with spill pipe (18) with threeway (15) by water pipe, spill pipe (18) is arranged on water tank (17) by water pipe mounting bracket (7), and through water tank (17) in the bottom of to link vacuum checking device (14) always.
As shown in Figure 2, under normal state, maintenance port lid (5) is arranged on service hatch (4), when needing repairing or clean, can pull down maintenance port lid (5), maintenance or cleaning water tank (17) inside.
As depicted in figs. 1 and 2, B/P EGR Back Pressure Transducer EGR (10), electric ball valve for mine (11), vacuum checking device (14) and electromagnetic valve for mine (16) are that the intelligent control system provided with working site is matching used, the signal that sensor collects can be passed to intelligent control system, and control the start-stop of electric ball valve for mine (11), electromagnetic valve for mine (16) and water pump (19) by intelligent control system.
As shown in Figure 4, the outer intake pipe (26) of water tank is bolted with suction sleeve (6) in water tank, water tank (17) is connected with water pump (19) by connecting tube (27), water pump diversion gate valve (21) is arranged on water pump aqueduct (22), water pump aqueduct (22) one end connects water pump (19), the other end connects electric ball valve (11), the other end of electric ball valve (11) is connected with diversion gate valve (23) and aqueduct (24), and aqueduct (24) the other end directly connects mine internal drainage pipeline.
As shown in Figure 4, when first time is toward in water tank and pump during diversion, need external smart control system to electric ball valve for mine (11) and electromagnetic valve for mine (16) signals, make it open, open water pump water-drawing gate valve (21) and diversion gate valve (23), water now in mine drainage pipeline can be back in conduit pipe, by connecting tube (27), water pump (19) and casing (17) are filled, during diversion, air in water tank (17) is discharged by spill pipe (18) after electromagnetic valve for mine (16) by exhaust weldless tube (13).When water in water tank (17) is full, can be detected by vacuum electromagnetic detection device (14), and give external smart control system electrical signal, the start-stop of water pump (19), electric ball valve for mine (11) and electromagnetic valve for mine (16) is controlled by external smart control system.Diversion is complete, electric ball valve for mine (11) and electromagnetic valve for mine (16) are closed, water pump is opened, now normally work, water is discharged by water pump (19), due to the existence of atmospheric pressure, continuously the water in sump is pressed in the middle of water tank (17) by the outer intake pipe (26) of casing.
