Description

Technical Field

[0001] This utility model relates to the field of steam boiler technology, and in particular to a steam boiler water supply structure. Background Technology

[0002] A steam boiler is a boiler device that produces steam. Steam boilers can be classified according to their fuel type, such as electric steam boilers, oil-fired steam boilers, and gas-fired steam boilers. When using a steam boiler, a water supply system is required. Common water supply systems consist of a water tank and a water pump.

[0003] However, existing steam boiler water supply devices are not convenient for controlling the water level and cannot guarantee that the water level in the water supply tank is always kept within a certain range. When the water in the water supply tank is too low, insufficient water supply can easily lead to damage to the water pump. Therefore, this utility model proposes a steam boiler water supply structure to solve the above problems. Utility Model Content

[0004] In view of the defects of the existing technology, the purpose of this utility model is to provide a steam boiler water supply structure.

[0005] To achieve the above objectives, this utility model provides a steam boiler water supply structure, including a tank body. A cover is detachably installed on the top of the tank body. A water inlet pipe is fixedly installed through one side of the upper end of the tank body, and a water inlet mechanism is connected to the outer end of the water inlet pipe. A water outlet pipe is fixedly installed through the other side of the lower end of the tank body. A solenoid valve is installed on the water inlet pipe. Vertical rods are fixedly installed on both sides of the tank body. A horizontal rod is slidably installed between the two vertical rods. Several floats are fixedly installed through the horizontal rod. A support rod is fixedly installed at the top of the horizontal rod. A stop block is fixedly installed at the top of the support rod. A horizontal plate is installed below the stop block. The horizontal plate is fixedly installed on the inner wall of the tank body. A groove is formed at the top of the horizontal plate, allowing the stop block to enter the groove. A pressure sensing plate is fixedly installed at the bottom of the groove. The pressure sensing plate is electrically connected to a pressure controller, and the pressure controller is electrically connected to the solenoid valve.

[0006] Furthermore, the bottom four corners of the cover are respectively fixed with insert rods, and the top four corners of the can are provided with slots. The insert rods are arranged in a one-to-one correspondence with the slots, and the insert rods are inserted into the slots.

[0007] Furthermore, a first magnetic block is fixedly disposed at the bottom end of the insertion rod, and a second magnetic block is fixedly disposed at the bottom of the slot, with the first magnetic block and the second magnetic block attracting and fixing each other.

[0008] Furthermore, a filter screen is movably mounted on the upper part of the tank body. The filter screen is located below the water inlet pipe. Vertical plates are fixedly mounted on the top four corners of the filter screen. Threaded rods are inserted through the side walls of the vertical plates. Threaded holes are opened on the inner wall of the tank body, and the threaded rods are threaded into the threaded holes.

[0009] Furthermore, positioning blocks are fixedly installed on the four sides of the lower outer wall of the tank, and support legs are fixedly installed on the outer wall of the positioning blocks.

[0010] Furthermore, support rods are fixedly installed at the four corners of the bottom of the tank, and support blocks are fixedly installed on the top of the support rods. A water pump is installed on the support block, and the water pump is fixedly connected to the water outlet pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Through the structure of the tank, float, crossbar, groove, pressure sensor, solenoid valve, and abutment, the crossbar floats on the water surface under the action of the float. When the water level drops, the float also drops continuously with the drop in water level. The support rod drops with the drop in float. When the support rod drives the abutment into the groove, when the abutment contacts the pressure sensor, the pressure sensor senses the pressure and transmits the pressure signal to the pressure controller. The pressure controller controls the solenoid valve to open, and the water inlet mechanism continues to add water to the tank through the water inlet pipe, so that the water level in the water supply tank is always kept within a certain range. This solves the problem that the existing steam boiler water supply device is not convenient to control the water level, it is difficult to ensure that the water level in the water supply tank is always kept within a certain range, and when the water in the water supply tank is too low, it is easy to cause insufficient water supply and damage to the water pump.
