Description

Novel intelligent dynamic constant flow balance temperature limiting device

Technical Field

The utility model relates to a balanced valve technical field, concretely relates to novel balanced limit for temperature of intelligence developments constant flow device.

Background

In the process of supplying heat to the whole building or the whole district, the centralized heating system inevitably has the conditions of high pressure and low flow of low pressure and low flow of high pressure and high flow of low pressure of high pressure and low flow of high pressure of hot water of the floor, and uneven heat supply between a high floor and a low floor, and between a near place and a far place. However, the conventional solutions at present are to install an electric actuator on each branch of the front-end water collector or to install an electric actuator (or an electronic actuator) on the two-way valve, and to control the opening or closing of the valve by the sensing of the temperature controller, thereby realizing the balance adjustment of heat supply. However, such a configuration also increases the difficulty of construction and post-maintenance, and when a fault occurs in one of the electric heating actuator, the temperature controller or the power supply system, the failure of heat supply balance can be directly caused.

However, as the conventional dynamic flow balance valve is continuously used, it gradually presents some disadvantages, and the occurrence of the disadvantages directly results in that the conventional dynamic flow balance valve cannot meet the high standard use requirement of the contemporary society, and the disadvantages of the conventional dynamic flow balance valve are now described as follows:

(1) because the existing dynamic flow balance valve is generally large in size and high in cost, the fact that one dynamic flow balance valve is installed in each household is difficult to achieve, and basically, one dynamic flow balance valve is installed at the water return end of each floor of each building or two adjacent floors of each building, so that heat supply flow balance among the floors is achieved.

(2) Because the service time of each household is different between the same floors and the set temperature in different time periods is possibly different, the electric heating actuator which is actually output by each branch circuit and controlled by the front end is in a long-term and frequent conversion working state, and the opening and closing of the water distributor and collector valves are continuously carried out, so that a large amount of heat resource waste is caused, the service life of the electric heating actuator is greatly shortened, and the difficulty of later maintenance is increased.

The working schematic diagram of the traditional dynamic flow balance valve is shown in the attached figure 2 of the specification, and the principle is as follows: the hot water supply flow among all floors is balanced through a high-power dynamic flow balance valve, the actual heat supply amount of each user of each floor is controlled by the actual opening of an electric heating actuator, when the indoor temperature is lower than the temperature set by the temperature controller, the temperature controller transmits a signal to the electric heating actuator, a push rod of the electric heating actuator contracts, the opening of the valve is increased, namely the flow of the introduced hot water is increased, and the indoor temperature of the user is increased; when the indoor temperature is higher than the temperature set by the temperature controller, the temperature controller transmits a signal to the first electric heating actuator, the push rod of the electric heating actuator is pushed outwards, the opening degree of the valve is reduced, and the indoor temperature of a user is reduced; the existing dynamic flow balance valve is generally large in size and high in cost, so that the situation that one dynamic flow balance valve is installed in each household is difficult to achieve, and basically, one dynamic flow balance valve is installed at the water return end of each floor of each building or two adjacent floors of each building, so that heat supply flow balance among the floors is achieved. However, because the service time of each household is different between the same floors and the set temperature may be different at different time periods, the electric actuator which is actually output by each branch controlled by the front end is in a long-term and frequent switching working state, and the opening and closing of the water distributor and collector valves are continuously performed, which not only causes the waste of a large amount of heat resources, but also greatly shortens the service life of the electric actuator and increases the difficulty of later maintenance.

The invention discloses a novel intelligent dynamic constant-flow temperature limiting device, which aims to solve the problems in heating systems such as floor heating systems or air conditioning systems and the like at present and realize the halving of heat supply for each family in a real sense.
