[0002] The electric control valve is composed of a dynamic flow balance valve and an electric control valve, and it can automatically adjust and maintain a preset flow rate under the condition of system pressure difference change.
[0003] The existing electric control valve has a relatively simple structure. When the system pressure difference suddenly changes greatly, the electric control valve itself cannot react in time, resulting in a sudden increase in flow rate and flow velocity, causing an impact on the inside of the valve body and affecting the service life of some parts inside the valve body. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a dynamic balance electric control valve to solve the above problems in view of the above problems existing in the prior art.
[0005] The purpose of the utility model can be achieved by the following technical solutions: A dynamic balance electric control valve includes a valve body with a water inlet and a water outlet. It is characterized in that a slow flow mechanism for slow flow is connected to the water inlet of the valve body.
[0006] The slow flow mechanism includes a slow flow cylinder communicated with the water inlet of the valve body, a rotating shaft located inside the slow flow cylinder, and several slow flow plates for slow flow.
[0007] The rotating shaft is vertically connected to the inside of the slow flow cylinder, and both ends are movably connected to the inner wall of the slow flow cylinder. The front end of the slow flow plate has an inclined edge.
[0008] Several tooth openings for facilitating slow flow and flow division are provided on the inclined edge of the slow flow plate.
[0009] The three slow flow plates are arranged at intervals along the outer wall of the rotating shaft in the circumferential direction and cooperate to form a slow flow part.
[0010] The slow flow parts are arranged at intervals in sequence on the rotating shaft and are arranged in a spiral structure. The radial dimension of the slow flow part in the middle of the rotating shaft is gradually decreasing from the middle of the rotating shaft to both ends.
[0011] In the above-mentioned dynamic balance electric control valve, several slow flow plates and the outer wall of the rotating shaft are integrally formed, and the slow flow plates are trapezoidally structured.
[0012] In the above-mentioned dynamic balance electric control valve, both ends of the rotating shaft are movably connected to the inside of the slow flow cylinder, and the rotation of the rotating shaft is realized through bearing parts. The slow flow and flow division effects can be realized through several slow flow part structures.
[0013] In the above-mentioned dynamic balance electric control valve, the slow flow cylinder is connected to the water inlet of the valve body through internal and external thread cooperation, and there is a seal between the thread connection parts to improve the sealing strength of the connection.
[0014] In the above-mentioned dynamic balance electric control valve, several of the slow flow plates can rotate through the rotating shaft and the water flow velocity, so as to achieve the slow flow effect.
[0015] Compared with the prior art, the structure of this dynamic balance electric control valve is simply designed. By setting a slow flow mechanism at the water inlet of the valve body, through the structural design of the slow flow mechanism, the fluid entering the valve body can be effectively slowed down, its impact force can be reduced, the loss of internal parts of the valve body can be reduced, and the service life of the valve body can be improved. At the same time, when the system pressure difference changes suddenly, the slow flow mechanism can slow down the fluid, so as to minimize the loss of internal parts of the valve body caused by the pressure difference change before the automatic adjustment of the valve body.

[0021] Such as Figure 1 , Figure 2 , Figure 3As shown in the figure, this dynamic balance electric control valve includes a valve body 1 with a water inlet and a water outlet. A flow buffering mechanism for buffering the flow is connected to the water inlet of the valve body 1. The flow buffering mechanism includes a flow buffering cylinder 2 communicated with the water inlet of the valve body 1, a rotating shaft 3 located inside the flow buffering cylinder 2, and a plurality of flow buffering plates 4 for buffering the flow.

At the same time, when the system pressure difference suddenly changes, the flow buffering mechanism can slow down the fluid, so as to minimize the loss of internal parts of the valve body 1 caused by the pressure difference change before the automatic adjustment of the valve body 1.
[0023] Furthermore, in order to improve the overall connection strength of the flow buffering mechanism, a plurality of flow buffering plates 4 and the outer wall of the rotating shaft 3 are integrally formed, and the flow buffering plates 4 are arranged in a trapezoidal structure.
[0024] Furthermore, in order to achieve the buffering of the fluid and prevent the impact loss of the internal parts of the valve body 1 caused by the pressure difference change, both ends of the rotating shaft 3 are movably connected inside the flow buffering cylinder 2, and the rotation of the rotating shaft 3 is realized through bearing parts. The buffering and flow splitting effects can be achieved through the structures of a plurality of flow buffering parts 5.
