Background

The single-port exhaust valve (exhaust valve) is applied to exhaust of pipelines such as an independent heating system, a central heating system, a heating boiler, a central air conditioner, floor heating and solar heating systems. Because water usually has some dissolved air, and the solubility of air decreases with increasing temperature, the gas gradually separates from water during circulation and gradually gathers together to form large bubbles and even gas columns, and because of the supplement of water, gas is often generated.

The patent No. CN200920192289.6 discloses a single-port exhaust valve, which comprises a valve body, a valve clack, a valve cover and a valve seat. The valve body is internally provided with a support, the lower end of the support is fixedly connected to the inner wall of the inlet side of the valve body, and the inner wall of the valve body is uniformly provided with guide ribs. The valve clack is made of ABS engineering plastic material, a closed cavity is formed in the center, a valve clack sealing ring is arranged in the upper plane, and the valve clack sealing ring is movably arranged between the upper plane of the support and the guide rib. Because the specific gravity of the ABS engineering plastic material is similar to that of water, the valve clack has thicker wall thickness and strong bearing capacity, the nominal pressure can reach PN4.0MPa, and the valve clack has the advantage of high working pressure. The pipeline negative pressure air suction device is suitable for a water supply and drainage system, and can suck external air when air accumulated in a pipeline and negative pressure in the pipeline are removed, so that the safety of the pipeline is ensured.
