Description

Technical Field

[0001] The utility model relates to the field of flow control valves, in particular to a flow control valve for a direct hot water supply unit. Background Art

[0002] The direct hot water supply unit is mainly used to directly supply hot water, usually for large buildings or industrial facilities. Its function is to efficiently heat and supply stable hot water to meet the water supply demand. The flow control valve is a flow control component of the direct hot water supply unit and plays a key role. Its core function is to regulate the water flow through the direct hot water supply unit, accurately control the water flow, and ensure that the amount of hot water output by the water supply system meets the demand.

[0003] However, the existing flow control valves are generally installed at the inlet and outlet ends of the direct hot water supply unit and are controlled by the operating handwheel of the flow control valve. However, due to external factors, the valve body of the flow control valve is often damaged, or the operating handwheel is accidentally triggered, resulting in the abnormal operation of the direct hot water supply unit.

[0004] Therefore, in view of the problem that due to external factors, the valve body of the flow control valve is damaged, or the operating handwheel is accidentally triggered, resulting in the abnormal operation of the direct hot water supply unit, a flow control valve for a direct hot water supply unit can be designed. Summary of the Utility Model

[0007] Preferably, in the first step, the support seat is placed at the lower end of the flow control valve body, and the height of the support seat is adjusted by the support feet so that the buffer pad at the upper end of the support seat is just cushioned at the lower end of the flow control valve body, and the buffer pad effectively reduces the vibration transmission of the flow control valve during operation, thereby improving the stability of the flow control valve;

[0008] In the second step, starting the moving assembly can control the upper protective cover to move inward synchronously, isolating the flow control valve body to prevent the external impact force from causing impact or damage to the flow control valve body;

[0009] The third step is to start the limiting component again, and the limiting component controls the plug to move upward and insert it into the gap between the operating wheels of the flow control valve body, thereby limiting the positioning of the operating wheel of the flow control valve body to avoid accidental touch or misoperation due to external influences.

[0010] Preferably, the support leg includes an anti-dump bracket, a counterweight, an adjustment column, an adjustment hole and a spring pin; the counterweight is fixedly connected to the lower end of the anti-dump bracket; the adjustment column is slidably connected to the upper end of the anti-dump bracket; and one end of the counterweight of the support leg is placed downward on the ground.

[0011] Preferably, the outer side of the anti-dump bracket is provided with adjustment holes which are evenly distributed vertically; the outer side of the adjustment column is provided with symmetrically distributed spring pins; the spring pins are engaged with the adjustment holes; the spring pins on both sides of the adjustment column are pressed to disengage them from the adjustment holes of the anti-dump bracket, and then the adjustment column is adjusted until the support seat is adjusted to a suitable height and the spring pins are stuck in the corresponding adjustment holes.

[0012] Preferably, the moving component includes a driving motor, a bidirectional threaded column, a threaded sleeve and a linkage block; a bidirectional threaded column is installed on the right end of the driving motor; when the driving motor is started, the bidirectional threaded column begins to rotate clockwise, and the threaded sleeve on the outside of the transmission moves inward synchronously, and the protective cover linked by the linkage block also closes accordingly.

[0013] Preferably, the outer side of the bidirectional threaded column is transmission-connected with a threaded sleeve symmetrically distributed on the left and right; the threaded sleeve is fixedly connected to the protective cover through a linkage block; if the protective cover is to be opened, the bidirectional threaded column can be driven in reverse.

[0014] Preferably, there are three plug posts; the upper ends of the plug posts are fitted into the gap between the operating wheels of the flow control valve body.

[0015] Beneficial effects of the utility model:

[0016] The utility model adds a support seat with a buffer pad at the bottom, which can stably support the flow control valve, effectively reduce the vibration transmission during the operation of the flow control valve, and improve the stability of the flow control valve. By setting a protective cover outside the valve body of the flow control valve, the body of the flow control valve is isolated to avoid the impact or damage of the external impact force on the valve body of the flow control valve. By inserting the limiting component into the gap of the operating wheel of the flow control valve body, the operating wheel of the flow control valve body is limited and positioned to avoid accidental touch and misoperation affected by the outside world, improve the safety of the flow control valve of the direct hot water supply unit, and ensure the long-term stable operation of the direct hot water supply unit.

[0025] See also Figure 4 In this embodiment, the moving component includes a driving motor 701, a bidirectional threaded column 702, a threaded sleeve 703 and a linkage block 704; a bidirectional threaded column 702 is installed at the right end of the driving motor 701; when the driving motor 701 is started, the bidirectional threaded column 702 starts to rotate clockwise, and the threaded sleeve 703 on the outer side of the transmission moves inward synchronously, and the protective cover 5 linked by the linkage block 704 also closes accordingly; the outer side of the bidirectional threaded column 702 is connected to a threaded sleeve 703 symmetrically distributed on the left and right; the threaded sleeve 703 and the protective cover 5 are fixedly connected by the linkage block 704; if you want to open the protective cover 5, you can drive the bidirectional threaded column 702 in the reverse direction.

[0026] When working, the first step is to place the support seat 2 at the lower end of the flow control valve body 1, adjust the height of the support seat 2 through the support foot 4, place one end of the counterweight block 402 of the support foot 4 downward on the ground, press the spring pins 405 on both sides of the adjusting column 403 to disengage it from the adjusting hole 404 of the anti-dump bracket 401, and then adjust the adjusting column 403 until the support seat 2 is adjusted to a suitable height, and the spring pin 405 is stuck in the corresponding adjusting hole 404, so that the buffer pad 3 at the upper end of the support seat 2 is just cushioned at the lower end of the flow control valve body 1, and the buffer pad 3 effectively reduces the vibration transmission of the flow control valve during operation, thereby improving the stability of the flow control valve.
