2. Background of the invention

The self-operated flow control valve is a valve which does not depend on external power and keeps constant flow function by adjusting the pressure difference inside the valve, the set flow is unchanged when the pressure difference is changed within the range of 0.02-0.3 Mpa, and the self-operated flow control valve has the function of displaying flow scales, and the passing flow can be known through the scales. Corresponding national standard GB/T29735-.

In the process of gradual development of the heating industry, a heating power company requires to be capable of adjusting balance, saving energy and supplying heat, and also to be capable of utilizing the internet to perform remote monitoring and adjustment, and especially to realize automatic intelligent control on management and control of heating fee collection, so that valves with electric actuators are developed in recent years, namely, manual valves such as ball valves and self-operated flow control valves are additionally provided with electric actuators and transmitted to a control platform through a network, and the valves can be adjusted and switched on and off on a computer, so that some problems are really solved, such as convenient adjustment and labor saving, and the remote valve closing without paying brings certain convenience, but through application and field investigation of an inventor, many defects are discovered, especially for household, the main defect of the manual valves is that the temperature of return water is unknown, although the valves are adjusted to a proper position according to scales, but due to pipeline blockage, the system problem is unknown, the effect of the return water temperature after adjustment cannot be determined, the adjustment is not fine enough, and more importantly, no means is provided for monitoring whether heat is stolen or not without paying or telling the stop of a house.

The main problems of using the electric self-operated flow valve are as follows:

1) the investment is large, the cost of the self-operated flow valve is higher than that of a common valve, and the installation cost of the waterway circuit is very large due to the uploading system of the electric actuator. Large area use is difficult to achieve without large investments.

2) Besides the problems of the valve, the problems of out-of-control network communication, artificial damage, power failure, disconnection and the like of a power supply system need to be handled and maintained, and still need great manpower resources. The inventor knows that the electric valve is installed to control the residents, so that the residents feel repugnance, and the problems that the electric head is dismantled to cut off the line occur. The small city is also a large system management and maintenance system with the residents of tens of thousands of households. The cost is high and requires professional teams to perform.

3) Influence heat supply, many places all close the valve as the sharp weapon of charge management and control to the motorised valve, for control charge before the heating, who pays for who opens, and the problem is when heating thousands of users pay fee together and need open all valves simultaneously, and all problems all concentrate on eruption in one or two days, and a time problem piles up and often encloses stifled heating power company.

4) The heat exchange station boiler room is not necessary to be adjusted for most years after the heat supply flow of the heat exchange station boiler room is adjusted, and the heat exchange station boiler room can be well adjusted to adapt to weather changes by using the water temperature after the flow of each household is well distributed. Therefore, each household is provided with a remote control regulating system, the actual use value is very low, from the aspect of charging control, the rate of defaulting and hot stealing households is at most 5%, and 5% of bad households are controlled according to 100% of investment, so that the situation that the defaulting and hot stealing households are not needed is high.

3. Summary of the invention

According to above problem and not enough, the utility model provides a take temperature measurement formula flow control valve that can upload, but the temperature probe of a measurable temperature of suitable position installation on original this type of valve and the collector that can show the temperature reach the network transmission system of platform with the temperature, the purpose is can see temperature monitor when field adjustment and adjust, can monitor its each family's return water temperature at any time on network platform, especially can monitor in focus to the user that does not pay fees and arrearages.

4. Description of the drawings

In the figure 1, (1) a self-operated flow control valve, (2) a temperature measuring probe, (3) a temperature collector, (4) a data concentrator and (5) a remote control platform.

5. Detailed description of the preferred embodiments

No matter the big valve and the small valve, a detachable temperature probe is installed at a proper position on the valve body, an output lead of the temperature probe is connected to a temperature collector, and signals are uploaded to a remote control platform through a data concentrator and a communication system.

The valve can be installed on the water return pipeline of the inlet of the heat supply household. When the water heater is used, the flow is firstly adjusted to a proper position according to factors such as the area size of a user, whether the side top layer faces the sun or not and the like, and the water heater can finish the operation by once fine adjustment according to the return water temperature during heating operation. The aim is that the return water temperature of each household is basically consistent in the same time period, namely the balance energy-saving requirement is achieved. If the temperature of the individual resident is found to be abnormal through the monitoring of the remote control center platform, the individual is dispatched to the site for disposal. If the backwater temperature of the individual residents is also hot, the residents who are mainly monitored are determined to be suspected of stealing heat, and then the residents are dispatched in time for treatment, so that the loss is reduced.

The practical significance of the invention is as follows: by utilizing the advantages of the Internet, the practical problems are pertinently solved by using small investment, and meanwhile, the workload is small and the maintenance amount is small. After each heating user installs the self-operated flow control valve with temperature uploading, the self-operated flow control valve is combined to have definite flow scale indication and constant-current anti-interference performance, manual adjustment is very quick and convenient, repeated adjustment is not needed, the heat supply effect and the room temperature condition of a resident can be analyzed and researched at any time by utilizing the advantage of uploading return water temperature, meanwhile, the dissatisfaction of the resident on flow control is not caused by uploading return water temperature, the losses of manual dismantling and damage on an electric actuator and the like are avoided, and the maintenance cost is low.

But can thoroughly solve the substantial problems of headache of a series of heat supply companies, such as long-term shortage and incomes, stealing of warm air, opening of human feelings and the like. Meanwhile, key monitoring measures can be adopted, for example, defaulting households and warming-up households are monitored in a single row and in a key mode one page, the workload is greatly reduced, and the effect of achieving double results with half the effort is achieved. The problem of centralized and sudden problems at a time point is also avoided because the problem of paying for and opening a valve is not involved, and heat supply cannot be influenced even if signals are uploaded smoothly or a network is interrupted sometimes. Because the auxiliary work is realized after normal heat supply, the temperature measuring probe system can be selectively installed according to the conditions, for example, the temperature measuring probe system can be selectively installed according to the condition of paying by residents and the condition that the position of a residence, such as the middle layer of the top layer and the bottom layer, is close to a gable wall, and the like, so the cost can be saved.
