Detailed Description

In order to improve the defect of the existing pressure stabilizing equipment in the background art, the box type automatic pressure stabilizing and water supplementing equipment is developed.

The box type automatic pressure stabilizing and water supplementing equipment comprises a box body 11 (for water filling effect) and a control box 1. The control box 1 is placed on the side face of the box body, and the control box 1 is placed on the side face of the box body 11, so that operation is facilitated. Be equipped with immersible pump 3 in box 11 (being used for moisturizing for heat exchanger group), immersible pump 3 welds in box 11 bottom through the support, and the immersible pump export is worn out the box 11 lateral wall and is passed through bolted connection check valve 4, and the check valve 4 other end passes through bolted connection shutoff ball valve 5, and the shutoff ball valve 5 other end passes through flange bolt and is connected with the flange moisturizing mouth of pipe 16 of heat exchanger group (the heat supply unit that current urban heating all adopted). The check valve prevents water in the heat exchanger unit from flowing backwards to impact the submersible pump, so that the submersible pump is damaged. The function of the shutoff ball valve is to cut off the water source when the heat exchange system equipment fails. The pressure sensor 15 is connected to the water replenishing pipe 17 of the heat supply unit through threads, and the pressure sensor 15 can detect the pressure of the heat exchange unit. The side wall of the box body 11 is connected with a liquid level meter 10 in a threaded mode, and the liquid level meter 10 is communicated with the interior of the box body. The gauge 10 allows an operator to observe the level of liquid in the tank. The manner in which the gauge 10 is connected to the tank is conventional and will not be described in detail. For example, the side face of the box body is provided with a hole, one end of the short pipe is welded on the hole, the other end of the short pipe is of a threaded structure, and the upper end interface and the lower end interface of the liquid level meter are in threaded connection with the short pipe. Make level gauge and the inside intercommunication of box like this for observe the liquid level in the box. Open porosely on another lateral wall upper portion of box 11, welded connection has inlet tube 9 on the hole, and inlet tube 9 and box 11 intercommunication go up through threaded connection upper water solenoid valve 13 on inlet tube 9, and upper water solenoid valve 13 and inlet tube are used for moisturizing for the box in. The water inlet pipe is connected with the water supply pipeline. The side wall of the box body at the lower part of the water inlet pipe 9 is provided with a hole, the hole is welded with an overflow drain pipe 2, and the lower end of the overflow drain pipe 2 is inserted into a sewer. The lower part of the overflow sewage discharge pipe 2 is connected with one end of a water drainage electromagnetic valve 14 through threads, the other end of the water drainage electromagnetic valve 14 is connected with the side wall of the box body through threads, and when the water quantity in the box body exceeds the standard water quantity, the water drainage electromagnetic valve is opened 14 to discharge water into a sewer through the overflow sewage discharge pipe 2. At the bottom of the box body, the sewage valve 6 is connected with one end of the sewage valve through threads, the other end of the sewage valve 6 is connected with the overflow sewage pipe through threads, when the impurities in the box body are more, the sewage and the impurities are discharged into the overflow sewage pipe through the sewage valve, and then the sewage is discharged into a sewer. The side wall of the box body 11 above the water draining electromagnetic valve is connected with a liquid level sensor in a threaded manner, and one end of the liquid level sensor is inserted into the box body. The manner in which the level sensor 12 is connected to the tank is conventional and will not be described in detail. For example, the side face of the box body is provided with a hole, a short pipe is welded on the hole, the other end of the short pipe is of a threaded structure, and one end of the liquid level sensor 12 is inserted into the box body and is in threaded connection with the short pipe, so that the liquid level sensor can detect the height of water in the box body. The pressure sensor, the submersible pump 3, the liquid level sensor, the water feeding electromagnetic valve and the water draining electromagnetic valve are respectively connected with the control box 1 through electric wires.

The control box is a control box commonly used in the market, and is produced by Senbo autonomous control equipment Co., Ltd. Control box 1 includes PLC18, converter 19 and power 20, and PLC18 passes through the screw fixation on control box 1 rear side wall, and below the PLC of converter 19 through the screw fixation at control box 1 rear side wall, power 20 passes through the screw fixation on control box 1 rear side wall, and the power is placed beside the PLC. Pressure sensor 15 passes through the electric wire and is connected with the PLC contact, PLC and converter connection of electric lines, converter connection of electric lines immersible pump 3, and level sensor 12 passes through the electric wire and is connected with the PLC contact, PLC and power connection of electric lines, and the power passes through the electric wire to be connected with last water solenoid valve 13 and sluicing solenoid valve 14 respectively. When pressure sensor 15 detects that the pressure in the heat exchanger group changes, pressure sensor 15 transmits a signal to PLC, PLC commands the converter, the converter commands the immersible pump, carries out the moisturizing level pressure to the heat exchanger group. When the water level in the box body changes, the liquid level sensor 12 transmits a signal to the PLC, the PLC controls the power supply to control the water feeding electromagnetic valve 13 or the water draining electromagnetic valve 14 to work, and the water level is kept at a required height.

And a layer of soundproof cotton is adhered to the outer side wall of the box body. The soundproof cotton plays the sound insulation, falls the fire prevention effect of making an uproar.

An access door 7 is arranged at the top end of the box body, and an inner ladder 8 is arranged on the side wall of the interior of the box body below the access door 7. And maintaining the whole equipment.

The automatic box type pressure-stabilizing water replenishing equipment has the advantages of simple structure, convenience in maintenance, convenience in installation, low possibility of damage, low noise, few leakage points, low investment and the like. Soundproof cotton is arranged outside the box body, so that noise reduction and fire prevention are realized.

The specific working process is as follows:

when the pressure of heating system changes, pressure sensor transmission signal gives PLC, and PLC dominates the converter, and the converter changes immersible pump behavior, and then gives the moisturizing level pressure of heat exchanger group. After water is supplied to the heat supply system, the water level in the box body drops, the liquid level sensor transmits signals to the PLC, the PLC controls the power supply, the water supply electromagnetic valve is controlled to work, and the water level is kept at the required height. If the water level is higher than the required height, the liquid level sensor transmits a signal to the PLC, the PLC controls the power supply, then the water drainage electromagnetic valve is controlled to work, and the water level is kept at the required height.

When the equipment is maintained, the blowoff valve is opened to discharge water and dirt in the equipment, and maintenance personnel enters from the access door and reaches the inside of the equipment through the inner ladder to maintain.
