Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
Referring to fig. 1, embodiment 1, this embodiment 1 provides a constant pressure moisturizing exhaust apparatus capable of feeding back a moisturizing amount, including a water pump 800, one end of the water pump 800 is connected to a normal pressure diaphragm tank body 600, which is characterized in that:
the other end of the water pump 800 is connected with a system through a pressure supplementing pipeline 300, and the system is connected with a pressure sensor 102;
the normal pressure diaphragm tank body 600 is connected with the system through a pressure relief pipeline 100, and the normal pressure diaphragm tank body 600 is communicated with an external water source through an external water supplementing pipeline 200;
the system is connected with a floor drain through a drainage pipeline 400;
the normal-pressure diaphragm tank body 600 is provided with a weighing sensor 700, and the weighing sensor is connected with a control box 900 (also called as central control); the atmospheric pressure membrane tank body 600 is provided with a vent elbow 500.
The weighing sensor 700 feeds back the water quantity condition of the normal pressure diaphragm tank body 600 to the control box 900 in real time.
The pressure relief pipeline 100 is provided with a pressure relief electric valve 101, the external water replenishing pipeline 200 is provided with an external water replenishing electric valve 201, and the drain pipeline 400 is provided with a drain electric valve 401.
The pressure sensor 102, the pressure relief electric valve 101, the water pump 800, the water discharge electric valve 401 and the external water supplement electric valve 201 are respectively connected with the control box 900 in a control way.
The control box 900 is connected to a central control device (not shown in the drawings) of the system. The central control device of the system is generally a device which is located in a central control room of a user and controls and monitors the operation of the system.
The specific operation is as follows: when the pressure sensor 102 detects that the pressure point of the system is smaller than the designed lower limit range of the pressure point, the water pump 800 is started (namely, the pressure sensor 102 feeds the condition of the system pressure back to the control box 900, and the control box 900 controls the water pump 800 to start), the water pump 800 pumps out the water in the normal-pressure diaphragm tank body 600 and replenishes water to the system through the pressure replenishing pipeline 300; until the pressure sensor 102 detects that the system pressure reaches the designed operating pressure point of the system, the control box 900 controls the water pump 800 to be closed to stop water supplement. In this process, the pressure release motor-operated valve 101, the water drain motor-operated valve 401, and the external water supply motor-operated valve 201 are all closed.
When the pressure sensor 102 detects that the pressure point of the system is larger than the designed upper limit range of the pressure point, the pressure relief electric valve 101 is started (namely, the pressure sensor 102 feeds the condition of the system pressure back to the control box 900, and the control box 900 controls the pressure relief electric valve 101 to start), and water in the system is released into the normal-pressure diaphragm tank body 600 through the pressure relief pipeline 100 until the system pressure is restored to the designed pressure point. When the working condition of the system changes, even if the pressure sensor 102 detects that the pressure point of the system is still larger than the designed upper limit range of the pressure point when the normal-pressure diaphragm tank body 600 is full, the electric drain valve 401 is opened (namely, the pressure sensor 102 feeds the condition of the system pressure back to the control box 900, meanwhile, the weighing sensor 700 feeds the water quantity condition of the normal-pressure diaphragm tank body 600 back to the control box 900 in real time, when the control box 900 detects that the pressure point of the system is still larger than the designed upper limit range of the pressure point when the normal-pressure diaphragm tank body 600 is full, the control box 900 controls the electric drain valve 401 to be opened), and the water of the system flows out through the drain pipeline 400 and enters the floor drain until the pressure is recovered to the designed pressure point. In this process, the water pump 800 and the external water replenishing electric valve 201 are both closed.
When the pressure of the system is not enough to restore to the designed pressure point due to a model selection error or due to a change of system working conditions, such as water leakage of the system, the external water supplement electric valve 201 is opened (that is, the pressure sensor 102 feeds the pressure of the system back to the control box 900, the weighing sensor 700 feeds the water quantity of the normal pressure membrane tank body 600 back to the control box 900 in real time, and the control box 900 concludes that the pressure of the system is not enough to restore to the designed pressure point, the control box 900 controls the external water supplement electric valve 201 to be opened), an external water source (such as a municipal water source and the like) enters the normal pressure membrane tank body 600 through the external water supplement pipeline 200, and finally water is supplemented to the system through the pressure supplement pipeline 300 under the action of the water pump 800. In this process, both the pressure release electric valve 101 and the water drain electric valve 401 are closed.
The utility model discloses when level pressure moisturizing exhaust apparatus externally supplied water motorised valve 201 was opened, the liquid level when can take notes ordinary pressure diaphragm jar body 600 (feed back control box 900 with the weight condition of ordinary pressure diaphragm jar body 600 this moment through weighing sensor 700), when the moisturizing of outside water source stopped, the liquid level of rerecording ordinary pressure diaphragm jar body 600 (feed back control box 900 with the weight condition of ordinary pressure diaphragm jar body 600 this moment through weighing sensor 700) to control box 900 can calculate the moisturizing volume. If the water supplement amount exceeds the set value, the control box 900 can feed back the relevant information to the central control equipment of the system (namely, the central control equipment transmits an alarm signal to the central control room of the user), and the central control equipment gives an alarm to the user of the system so as to timely maintain the normal-pressure diaphragm tank body 600 and/or the system and reduce the loss.
The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, are included in the same way in the protection scope of the present invention.
