The water storage container also comprises a screen plate vertically inserted into the tank body, and the screen plate is vertical to the water outlet of the water storage container.

The flange cover is connected with the tank body through a flange.

The liquid level meter is arranged on the outer surface of the tank body, and is a glass tube with an upper valve and a lower valve arranged at two ends respectively.

The installation position of the upper water level float switch is higher than that of the drain valve.

The bottom of the tank body is provided with a drain valve.

The energy-saving drainage device is arranged at the bottom of the branch cylinder.

The utility model has the advantages that: the utility model discloses energy-conserving hydrophobic means increases the jar body of collecting the comdenstion water and the controller of control solenoid valve switch on the basis of trap for steam is accomplished and can not be got into the trap, thereby has avoided the waste of steam, has reached energy-conserving purpose.

Detailed Description

For better illustration of the present invention, the following description will be made with reference to the accompanying drawings.

As shown in fig. 1, the energy-saving drainage device includes a water storage container 1, a drainage valve 6 disposed at a lower portion of the water storage container 1, an electromagnetic valve 7 connected to the drainage valve 6, an upper water level float switch 2 and a lower water level float switch 3 mounted inside the water storage container 1, and a controller 5 capable of receiving signals of the upper water level float switch 2 and the lower water level float switch 3 and controlling the opening and closing of the electromagnetic valve 7, wherein the water storage container 1 includes a tank 13, a flange cover 11 fixedly mounted at an opening of the tank 13, and a water inlet 12 disposed at a center of the flange cover 11 and perpendicular to the flange cover 11. Preferably, the water storage container 1 further comprises a screen plate 14 vertically inserted into the tank body 13, and the screen plate 13 is perpendicular to the water outlet of the water storage container 1. The mesh 13 can isolate the impurities in the tank 11 without entering the trap 6 and the solenoid valve 7 to avoid valve damage. The flange cover 11 and the tank body 13 are connected through flanges, so that the assembly, disassembly and maintenance are convenient. Further, still include level gauge 4, level gauge 4 installs in jar body 13 surface, and level gauge 4 is the glass pipe that valve 41 and lower valve 42 were installed respectively to both ends, and when last valve 41 and lower valve 42 opened the back, both ends and jar body 13 intercommunication about the glass pipe, and operating personnel can be convenient look over the water level height through the glass pipe. Specifically, the installation position of the upper water level float switch 2 must be higher than the installation position of the steam trap 6 to ensure that steam cannot enter the steam trap 6 at the lowest water level. The drain valve 15 is installed at the bottom of the tank body 13, and an operator can manually open the drain valve 15 to drain condensed water and impurities remained at the bottom of the tank body 13.

As shown in fig. 1, the condensed water flows into the tank 13 from the water inlet 12 and gradually collects in the tank 13, and when the condensed water exceeds the water level of the trap 6, the trap 6 is opened, but the solenoid valve 7 is closed. When the water level reaches the position of the upper water level float switch 2, the ball body floats, the controller 5 receives the signal of the upper water level float switch 2 and then opens the electromagnetic valve 7, the condensed water is discharged through the drain valve 6 and the electromagnetic valve 7, when the water level drops to the position of the lower water level float switch 3, the controller 5 receives the signal of the lower water level float switch 3 and then closes the electromagnetic valve 7, and the condensed water in the tank body 13 starts to gather again, so that the operation is repeated.

As shown in fig. 2, further, the energy-saving drainage device is installed at the bottom of the air cylinder 8, and the condensed water in the air cylinder 8 can be drained through the energy-saving drainage device, so that the waste of steam is avoided.

The above description is only for the preferred embodiment of the present invention and should not be taken as limiting the invention, and any modification, equivalent replacement or improvement made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
