Abstract
The utility model discloses an automatic overpressure protection device for a water treatment system, so as to solve the technical problem that the existing automatic overpressure protection device for the water treatment system is over high in cost. The adopted technical scheme is that the overpressure protection device comprises a pressure relief drainage pipe, a pressure relief device, and a control device communicated with a water pipeline. The key points are that the pressure relief device comprises a water pressure sensor arranged inside the pressure relief drainage pipe and connected with the control device, and a pressure relief valve arranged on the pressure relief drainage pipe; the water pressure sensor collects a pressure signal inside the pressure relief drainage pipe, the signal after treatment is outputted to the control device, the control device treats the signal and then outputs the control signal to the pressure relief valve. The automatic overpressure protection device for the water treatment system has the technical effects that automatic control is realized; the water pressure sensor, the pressure relief valve and the control device can be used to monitor and automatically control the pressure inside the pressure relief drainage pipe in real time, normal operation of the water treatment system can be realized, and the operation cost and the maintenance time of the water treatment system are reduced.
Description
Technical field
The utility model belongs to water treatment facilities technical field, relates to the automatic over-pressure safety device of a kind of over-pressure safety device, particularly a kind of water treatment system.
Background technology
Potable water refers to people's drinking-water and domestic water, main by drinking-water and food per os, take in body, and can be by washing one's face and rinsing one's mouth, the domestic water contact skin such as washing articles, shower or breathe absorption human body.Potable water and health and quality of life are closely related, and its importance is not second to food.Along with the continuous increase of the discharge capacity of industrial waste water, exhausting sewage and agricultural chemicals, fertilizer amount, many drinking water sources are polluted, water pollutant content severe overweight, and increasing chemistry even toxicologic index exceed standard.Due to water quality deterioration, urban and rural residents' drinking water quality and the sanitary condition of directly drinking surface water and shallow ground water are difficult to ensure.Therefore, we could use after must utilizing water treatment system to process contaminated potable water.In water treatment system, be generally all provided with over-pressure safety device, in case locking system hypertonia causes pipeline breaking or valuable RO film to suffer that back pressure is broken, change.Existing hydraulic protector is the rupture disk that is arranged on reverse osmosis produced water water pipe; when system pressure is too high, rupture disk breaks; utilize the draining of pressure release drainpipe to reduce pressure; but this rupture disk hundreds of yuan; and be disposable; once break, can not reuse, the rupture disk that can only more renew has caused improving the operating cost of reverse osmosis water treatment system.
Summary of the invention
The purpose of this utility model is in order to solve the too high technical matters of over-pressure safety device cost of existing water treatment system; in order to address this problem; we have designed a kind of automatic over-pressure safety device of water treatment system; realized robotization control; can Real-Time Monitoring and automatically control the pressure of pressure release drainpipe inside; water treatment system can normally be moved, reduced operating cost and the maintenance time of water treatment system.
The concrete technical scheme that the utility model adopts is: a kind of automatic over-pressure safety device of water treatment system; comprise the pressure release drainpipe, pressure relief device and the control device that are communicated with hydraulic pipeline; key is: described pressure relief device comprises and is arranged on the inner hydraulic pressure sensor being connected with control device of pressure release drainpipe and is arranged on the blowdown valve on pressure release drainpipe; hydraulic pressure sensor gathers the pressure signal of pressure release drainpipe inside; after processing, output signal to control device, control device is exported control signal to blowdown valve after processing.
The beneficial effects of the utility model are: realized robotization control, utilize hydraulic pressure sensor, blowdown valve and the control device can Real-Time Monitoring and automatically control the pressure of pressure release drainpipe inside, water treatment system can normally be moved, reduced operating cost and the maintenance time of water treatment system.In pressure relief device, also comprise the warning circuit being connected with control device, pressure in water treatment system is excessive and blowdown valve breaks down in the time of cannot processing, warning circuit can send sound and light alarm signal, makes staff take in time corresponding measure, avoids water treatment system to be subject to badly damaged.
Accompanying drawing explanation
Fig. 1 is theory diagram of the present utility model.
In accompanying drawing, 1 represents hydraulic pressure sensor, and 2 represent control device, and 3 represent blowdown valve.
Embodiment
A kind of automatic over-pressure safety device of water treatment system; comprise the pressure release drainpipe, pressure relief device and the control device 2 that are communicated with hydraulic pipeline; key is: described pressure relief device comprises and is arranged on the inner hydraulic pressure sensor 1 being connected with control device 2 of pressure release drainpipe and is arranged on the blowdown valve 3 on pressure release drainpipe; hydraulic pressure sensor 1 gathers the pressure signal of pressure release drainpipe inside; after processing, output signal to control device 2, control device 2 is exported control signal to blowdown valve 3 after processing.
Described blowdown valve 3 is solenoid valve or operated pneumatic valve.
In described pressure relief device, also comprise the warning circuit being connected with control device 2, warning circuit is sound and light alarm mode.
The utility model is in the specific implementation: when the pressure of pressure release drainpipe inside is excessive while surpassing set pressure, hydraulic pressure sensor 1 is exported to control device 2 by the pressure signal collecting, when control device 2 detects pressure and exceeds the safety value of setting, output control signal is to blowdown valve 3, blowdown valve 3 is opened and is carried out pressure release, if blowdown valve 3 breaks down, cannot open, control device can output signal to warning circuit and carry out sound and light alarm, and staff can be taken appropriate measures in time.When the pressure of pressure release drainpipe inside recovers normal, by recovery and protection state after manual confirmation: hydraulic pressure sensor 1 is exported to control device 2 by the pressure signal collecting, control device 2 is exported control signal to blowdown valve 3 after processing, and blowdown valve 3 cuts out.Robotization is controlled, and water treatment system can normally be moved, and has reduced operating cost and the maintenance time of water treatment system.
