Abstract
The utility model relates to an energy-saving type self-control fluorine-lined regulating valve which comprises a valve body, wherein a middle cavity is arranged at the middle part of the valve body, the left side and the right side of the middle cavity are communicated with an inlet flow passage and an outlet flow passage respectively, a valve clack is arranged in the middle cavity of the valve body, a valve cover is arranged at the top end of the valve body, the end part of a valve rod penetrates through the valve cover and is connected with the valve clack, the valve rod is driven by an electric actuating mechanism and the energy-saving type self-control fluorine-lined regulating valve is characterized in that the inlet flow passage is horizontal, a circular arc surface is adopted between the horizontal inlet flow passage and the middle cavity for transition and a large-angle through oval section structure is arranged at the junction of the middle cavity and the outlet flow passage. The structure of the flow passages in the valve body of the energy-saving type self-control fluorine-lined regulating valve can avoid the violent impact phenomenon between fluid at an inlet and the middle cavity. The fluid resistance entering the middle cavity and the energy consumption of a system are greatly reduced, the fluid can smoothly pass through and the heat transformation loss during heating up of the system can be effectively reduced, thereby playing the roles of consumption reduction and energy conservation. Further, a conical seal is adopted, granular matters can not stop on the sealing surface and the sealing surface can be effectively protected.
Description
Technical field
The utility model relates to a kind of energy-saving automatic control lining fluorine modulating valve, is applicable on the fluid circuit that the device as automatic control and adjusting flow belongs to valve technology field.
Background technique
As shown in Figure 1, be existing automatic control and adjustment valve, comprise valve body 13, valve body 13 middle parts are lumen, and the left and right sides of lumen is communicated with inlet channel and outlet flow respectively, are provided with flap 14 in the lumen of valve body 13, the top of valve body 13 is provided with valve gap 4, the end of valve rod 5 is passed valve gap 4 and is linked to each other with flap 14, and by sealing strip 17 sealings, valve rod 5 is driven by electric actuator 18 between valve rod 5 and the valve gap 4.
The shortcoming of said structure is: 1, lumen, inlet channel and the outlet flow in the valve body 13 is S-shaped, fluid has the phenomenon that clashes when entering the valve body lumen, noise increases, and the flow resistance and the system energy consumption that enter in the lumen are very big, fluid is also very big from the resistance that lumen flows out, the flow resistance and the system energy consumption that flow out lumen are improved greatly, thus the thermal transition loss that causes system to heat up.2, flap 14 generally adopts plane sealing with the sealing of valve body 13, stops if any granular rubbish, and its sealing surface destroys easily.
Summary of the invention
The purpose of this utility model provides the little modulating valve of a kind of thermal transition loss.
In order to achieve the above object, the technical solution of the utility model has provided a kind of energy-saving automatic control lining fluorine modulating valve, comprise valve body, the valve body middle part is a lumen, the left and right sides of lumen is communicated with inlet channel and outlet flow respectively, be provided with flap in the lumen of valve body, the top of valve body is provided with valve gap, the end of valve rod is passed valve gap and is linked to each other with flap, valve rod is driven by electric actuator, it is characterized in that: inlet channel is a level, adopts the arc surface transition between horizontal inlet runner and the lumen, and lumen is that wide-angle is passed through the oval cross section structure mutually with the outlet flow connecting part.
Further, adopt conical surface seal between described flap and the described valve body.
The part overcoat that is positioned at described lumen at described valve rod is useful on the bellows of sealing.
Adopt packing seal between described valve rod and the described valve rod, filler is compressed by Gland.
Be connected with between described electric actuator and the described valve gap and be connected support, be provided with scale on the inwall that connects support, described valve rod links to each other with described electric actuator by contiguous block, is being provided with the pointer that is used for indicating graduation on this scale on the contiguous block.
A kind of energy-saving automatic control lining fluorine modulating valve that the utility model provides, the flow passage structure in its valve body can make the fluid of inlet and lumen not have the phenomenon of clashing.The flow resistance and the system energy consumption that enter in the lumen greatly reduce, and fluid can freely so pass through, and have effectively reduced the thermal transition loss that system heats up, and have played the energy-conservation of consumption reduction effect.Further, adopt conical sealing, shot-like particle can not stop at sealing surface, effectively must protect sealing surface.
