Description

Technical Field

[0001] The utility model belongs to the technical field of valves and relates to a heating valve, in particular to a flow-controllable heating valve. Background Art

[0002] Heating valves control the heating effect of heating equipment by regulating the amount of hot water flowing through the valve. Specifically, different valve openings correspond to different water flow rates. When the indoor temperature is below the set point, the valve opens or opens wider, increasing the water flow rate and thus raising the indoor temperature. When the indoor temperature reaches the set point, the valve closes or partially closes, reducing the water flow rate and thus lowering the indoor temperature.

[0003] The temperature of hot water in the heating pipe fluctuates, so the flow needs to be controlled by adjusting the heating valve. Traditional heating valves are only equipped with a rotating cap, which may rotate too much or too little, making it difficult to stably adjust to a comfortable temperature. If other factors appear in the heating pipe, it will seriously affect the use of heating. Therefore, research and development of heating regulation control and exhaust are needed. Summary of the Invention

[0004] The purpose of the utility model is to provide a flow condition controllable heating valve which is easy to install in order to solve the above problems in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a flow-controllable heating valve, characterized in that it includes a valve body provided with a water inlet and a water outlet, the valve body is also provided with a control chamber, the control chamber is provided with a control component, the water inlet is provided with a positioning ring, the water inlet is also provided with a plurality of L-shaped clamping blocks, a connecting pipe is provided on the water inlet, a guide groove is provided on the inside of the connecting pipe, and a clamping transverse groove is provided at the bottom of the guide groove, a positioning boss is also provided on the inside of the connecting pipe, a mechanical seal is provided on the positioning boss, the positioning ring is provided with a directional protrusion, and the top of the connecting pipe is provided with a directional opening groove.

[0006] In the above-mentioned flow-controllable heating valve, a plurality of scale indicators are provided on the outer wall of the control cavity, a rotating cap is provided on the control assembly, and a protrusion with an indicating arrow is provided on the rotating cap.

[0007] In the above-mentioned flow-controllable heating valve, a symmetrical clamping platform is provided on the valve body.

[0008] In the above-mentioned flow-controllable heating valve, an exhaust screw is provided on the valve body.

[0009] Compared with the existing technology, this flow-controllable heating valve is connected to the pipe fittings by setting an L-shaped clamping block and a clamping horizontal groove, and is locked by the elastic support of the mechanical seal. The directional protrusion prevents the valve body from being installed in the wrong direction. When in use, the opening range is accurately controlled by the indicator arrow and scale indication, making the temperature control more accurate and comfortable. The gas in the valve body can be reduced by disassembling and assembling the exhaust screw. BRIEF DESCRIPTION OF THE DRAWINGS
