Embodiment 1

[0076] A balance valve regulator 1, such as figure 1 As shown, it consists of the following parts:

[0077] The detection device is two pressure sensors connected to the water inlet end and the water outlet end of the balance valve 2, and is used to detect the water pressure in the balance valve 2, and it can also be set at other positions of the balance valve 2 here, However, the water pressure in the balance valve 2 can be better obtained by being arranged at the water outlet end and the water inlet end of the balance valve 2;

[0078] The electric motor provides driving force;

[0079] The transmission mechanism is connected with the electric motor, and the reduction gear set in the transmission mechanism is driven by the electric motor, and then the rotational torque of the reduction gear set is converted into linear thrust, and the output end of the thrust is provided with the The push rod connected to the valve stem of the balance valve 2, the push rod drives the valve c...

Embodiment 2

[0090] A balance valve intelligent adjustment system composed of the balance valve regulator 1 described in Embodiment 1, such as image 3 shown, including the following parts:

[0091] The balance valve 2 is arranged on the pipeline 7 to control the water flow on the pipeline 7 , the water source 6 flows through the pipeline 7 , and the balance valve 2 is arranged on each pipeline 7 .

[0092] The balance valve regulator 1 detects the water pressure at the water inlet and outlet ends of the balance valve 2, sends the detection results, and also receives control instructions to adjust the opening of the balance valve 2.

[0093] The central control system 3 includes a computer 4 and the adjustment software of the water supply system balancing valve arranged on the computer 4 . Through the data transmission between the signal transmission equipment and the balance valve regulator 1, the water pressure of the balance valve 2 transmitted by the balance valve regulator 1 is obtai...

Abstract

The invention relates to a balance valve adjuster, comprising a detection apparatus, a motor, a transmission mechanism, a feedback circuit, a controller and signal transmission equipment. The invention further relates to an intelligent balance valve adjusting system composed of the balance valve adjuster, comprising a balance valve, the balance valve adjuster and a central control system. Motions of the balance valve adjuster are controlled by the central control system, thereby opening degree of the balance valve is controlled and intelligent adjusting is realized. Provided are automatic intelligent adjusting equipment and a method, according to the invention, tedious working of the personnel on-site is not required, and update can be carried out momentarily. The equipment and the method solve the problem of expensive adjusting cost for the professional personnel and greatly reduce adjusting time, and that balancing adjustment can be carried out momentarily by managers according to system changes so as to save energy.

Description

technical field [0001] The invention relates to an intelligent adjustment system, in particular to an intelligent adjustment system and method for a balance valve in a water circulation system. Background technique [0002] A balance valve is a valve that regulates water pressure and controls flow under hydraulic conditions, and is often used in water circulation systems. For example, in the water circulation system of central air conditioning or central heating, balance valves are generally installed on each water circulation pipeline to adjust the flow rate. [0003] The balance valve in the prior art is usually provided with a handwheel, and the opening of the valve is adjusted by turning the handwheel, so as to control the water pressure. For example, a balance valve is disclosed in Chinese patent document CN101245869B, which includes a hand wheel, a valve body with a water inlet chamber and a water outlet chamber, a valve core and a valve stem that are obliquely arrang...
