Embodiment Construction
[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0019] Such as figure 1 and figure 2 As shown, the heating circuit automatic replenishment valve in this embodiment includes a valve body 1 , a valve core 2 , a spring 3 , an adjusting rod 4 , a membrane 5 and a cover 6 .
[0020] The valve body 1 has a water supply channel 11 and an axial channel 12 intersecting with the water supply channel 11. The two ends of the water supply channel 11 form a water inlet 111 and a water outlet 112. One end of the axial channel 12 has a first water chamber 121 and a second water chamber. cavity 122, one end of the first water cavity 121 communicates with the water supply channel 11 through the pressure feedback channel 13, and the other end communicates with the second water cavity 122, the second water cavity 122 has an opening on one side and is provided with a film 5, the second One side of the water ...

An automatic water supply valve for a heating circuit, which is characterized in that it includes a valve body, a valve core and a spring. The valve body has a water supply channel and an axial channel intersecting the aforementioned water supply channel. One end of the aforementioned axial channel has a first water chamber and a second water chamber. One end of the aforementioned first water chamber communicates with the water replenishment channel through the pressure feedback channel, and the other end communicates with the second water chamber. One side of the second water chamber is open and a film is provided. One side of the second water chamber A connecting channel is provided; the valve core is arranged in the axial channel of the aforementioned valve body so that it can move axially, and the valve core has a rod part, an enlarged part, a plug part and an abutting part sequentially from front to back. The automatic water supply function of the heating furnace to the heating circuit is realized in a purely mechanical way, which brings great convenience. The structure of the automatic replenishment valve is simple, and the work is reliable and stable.
Description
technical field [0001] The invention relates to a water replenishment valve, in particular to a water replenishment valve applied to a heating furnace. Background technique [0002] A prerequisite for the heating furnace to operate is that the water pressure in the heating water circuit reaches a preset value. If it is lower than this preset value, the heating furnace will not work. Due to the micro-leakage and evaporation of the heating pipeline, the water pressure in the heating pipeline often appears to be too low. Therefore, during the installation and subsequent use of the heating furnace, it is often necessary to replenish the heating circuit. [0003] The most commonly used method is manual water replenishment. However, it is not very accurate to grasp the timing and amount of water replenishment manually as a user. Therefore, there are often situations where too much water is added to cause the heating pipeline to burst, and special practitioners are often invite...
