[0024] The following further explains and illustrates the present utility model in conjunction with the accompanying drawings and specific embodiments.

[0025] Embodiment 1

[0026] As Figures 1-6 shown, the high-temperature water tank pump valve skid-mounted device disclosed by the present utility model includes a water tank 1 and a water softener 2 that are interconnected, and the water tank 1 is connected to a water outlet pipe 9; the water tank 1 includes a water tank body 1-1, and a hot water area and a cold water area are separately provided in the water tank body 1-1. The hot water area is connected to a first heat exchange loop, and the cold water area is connected to a second heat exchange loop. The first heat exchange loop includes a customer printing press interface 1-7 provided in the hot water area and a customer printing press return water interface 1-10 provided in the cold water area. The customer printing press interface 1-7 and the customer printing press return water interface 1-10 are connected to a printing press and form a circulation loop; the second heat exchange loop includes a heat exchanger interface 1-6 provided in the cold water area and a heat exchanger return water interface 1-8 provided in the hot water area. The heat exchanger interface 1-6 and the heat exchanger return water interface 1-8 are connected to a heat exchanger and form a circulation loop.

[0027] In this embodiment, the water softener 2 receives tap water from the customer, and after being processed by the water softener, it is sent to the water tank 1. The water tank is used to store softened water. The water tank body 1-1 is welded with stainless steel, and has a partition inside to divide it into cold water and hot water areas. The water tank body 1-1 is wrapped with external insulation to ensure that the water tank has less heat loss. The interface 1-7 to the customer's printing machine and the return water interface 1-10 to the customer's printing machine are both welded on the water tank body 1-1, which is a circulation loop for sending hot water to the printing machine, and sending cold water back after heat exchange for reheating. The interface 1-6 to the heat exchanger and the return water interface 1-8 to the heat exchanger are also welded on the water tank body 1-1, which is another circulation loop for sending cold water to the heat exchanger, and after obtaining heat, hot water is fed back to the hot end of the water tank body 1-1 to save heat. The two sets of circulation loops make the heat stroke of the whole device a limited equilibrium state. The unheated softened water in the water tank 1 enters the outlet pipe 9, passes through the stop valve 4, and enters the Y-type filter 5. The Y-type filter 5 will filter out the particulate impurities in the soft water to prevent them from clogging the outlet pipe 9 and damaging the water pump 7. After being pressurized by the water pump 7, it enters the subsequent outlet pipe 9. The water pump 7 is set up with one for use and one for standby. If one water pump 7 cannot run, the other will start automatically to ensure the pressure of the outlet pipe 9. The stop valve 4 is also set after the water pump 7 for replacement of the water pump 7. The pressure gauge 6 is set before and after the water pump 7. According to the value displayed by the pressure gauge 6, the state of the water pump 7 can be judged. The control instrument can be installed on the outlet pipe 9 after the water pump 7, and then the heat exchanger is inserted to obtain heat and return to the hot water area of the water tank 1 for use. In the whole process, the pipe elbows should be as few as possible and the length should be as short as possible, which can ensure that the water flow pressure loss is less, the water flow is smoother, and the system is more stable. The water pumps 7 are arranged side by side to save space and facilitate maintenance.

[0028] Example 2

[0029] On the basis of Example 1, in the utility model, a magnetic flap level gauge 1-2 and a glass tube level gauge 1-3 are fixedly connected to the inner wall of the water tank body 1-1. A water tank base 1-9 is fixedly connected to the bottom of the water tank body 1-1 and the water softener 2. A water tank exhaust port 1-11 is opened at the top of the water tank body 1-1 in the hot water area; a manhole 1-12 is opened at the top of the water tank body 1-1 in the hot water area and the cold water area; a sewage outlet 1-13 is fixedly connected to the bottom of the water tank body 1-1 in the hot water area and the cold water area; a ladder 1-4 is fixedly connected to the side wall of the water tank body 1-1, and an overflow port 1-5 is opened at the top of the side wall of the water tank body 1-1; the ladder 1-4 is used to open the manhole 1-12 for observation and climb up the water tank 1; the overflow port 1-5 is used in case of a malfunction, the water level rises out of control, and overflows from the overflow port 1-5 when it exceeds the overflow port 1-5.

[0030] In this embodiment, the magnetic flap level gauge 1-2 and the glass tube level gauge 1-3 are both installed on the water tank body 1-1 to display the soft water level in the water tank. The magnetic flap has a signal feedback function, and the feedback water level height is used to control the operation of the water pump 7. The water tank body 1-1 and the water softener 2 are both placed on the water tank base 1-9. The water tank exhaust port 1-11 is used to balance the internal pressure of the water tank, prevent pressure damage and discharge water vapor. The manhole 1-12 is used for inspecting the inside of the water tank, including the cold end and the hot end, and two are set. The sewage outlet 1-13 is welded to the bottom of the water tank body 1-1 and is used for discharging sewage and cleaning the inside of the water tank.

[0031] Embodiment 3

[0032] On the basis of Embodiment 1, in the present utility model, the water softener 2 includes a water softening controller 2-3, and the water softening controller 2-3 controls the connection state with the water tank 1. After the water softener 2 obtains tap water, its operation is controlled by the water softening controller 2-3. Whether it is to enter the resin tank 2-1 to soften the hardness, or to restore the activity of the resin particles with the water in the salt box 2-2, or to send water into the water tank, it is all controlled by the water softening controller 2-3. The general working process of soft water is pretreatment (filtering impurities), ion exchange (softening), regeneration (restoring the activity of particles with brine), flushing (removing impurities), and storage (sending water). The treated soft water will be sent into the water tank body 1-1 for storage to supplement the water consumed in the circulation process. The water softener 2 is placed on the water tank base 1-9, and the resin tank 2-1 and the salt box 2-2 are both fixed on it with steel plates to prevent tipping and facilitate transportation. The water softener 2 and the water tank 1 are combined into a module for hoisting and transportation. Two stop valves 4 are provided on the water outlet pipe 9. Along the direction away from the water tank 1, a Y-type filter 5 and a check valve 8 are sequentially provided between the two stop valves 4. A water pump 7 is provided between the Y-type filter 5 and the check valve 8. Pressure gauges 6 are provided on both sides of the water pump 7 between the Y-type filter 5 and the check valve 8. The water outlet pipe 9 is connected to the water tank 1 through the water inlet pipe 3. The water inlet pipe 3 is connected to a plurality of water outlet pipes 9, and it can be determined whether to arrange them in a double row or a single row according to the on-site situation to save on-site space and make the layout more compact. The bottom of the water outlet pipe 9 is connected to a pump valve support 10.

[0033] In the present utility model, the water tank 1 and the water softener 2 are placed on a base 1-9 and can be hoisted and transported separately. The remaining water outlet pipes 9, water pumps 7, valves, etc. are all installed on the pump valve support 10 and can be hoisted and transported separately. These form two major modules that can be assembled on-site, which is very convenient. Since the pressure gauge 6 is easily damaged during transportation, the pressure gauge 6 and the corresponding parts are packaged and installed on-site. After the water tank module and the water pump module of the present utility model are transported to the site, they are assembled, and then the pipeline is connected to the high-temperature hot water heat exchanger on-site, thus forming a complete set of water circulation system that can be controlled and put into use.
