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 ...

The invention discloses a heating loop automatic water supplementary valve which is characterized by comprising a valve body, a valve element and a spring, wherein a water supplementary channel and anaxial channel intersected with the water supplementary channel are arranged in the valve body; a first water cavity and a second water cavity are formed in one end of the axial channel; one end of the first water cavity communicates with the water supplementary channel through a pressure feedback channel; the other end of the first water cavity communicates with the second water cavity; an opening is formed in one side of the second water cavity, and a leather film is arranged on one side of the second water cavity; a connecting channel is arranged on one side of the second water cavity; andthe valve element moves in the axial direction to be arranged in the axial channel of the valve body and is sequentially provided with a rod part, an expansion part, a plug part and a leaning part from front to back. The heating loop automatic water supplementary valve adopts the purely mechanical manner to realize the automatic water supplementary function of a heating furnace to a heating loop so as to bring about great convenience. The heating loop automatic water supplementary valve is simple in structure and reliable and stable in working.
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...
