Problems solved by technology

[0003] The traditional range hood check valve is blocked by mechanical transmission, and the mechanical structure is prone to failure after long-term use. At the same time, it is blocked by a spring. Due to the multiple expansion and contraction of the spring, the expansion and contraction constant of the spring changes, resulting in the flue sealing effect. Poor, there is a problem of smoke return from the check valve and slow exhaust

Abstract

The invention belongs to the technical field of check valves, and particularly relates to a magnetic check valve for a range hood and a bath heater. A linear bearing is mounted in one end of a reset sleeve, a telescopic rod is movably sleeved with the linear bearing, a baffle is fixed to the end, located outside the reset sleeve, of the telescopic rod, and a buffering assembly is fixed to the end, located in the reset sleeve, of the telescopic rod. Deflection protruding lines are welded to the outer side surface of the baffle, a supporting ring is welded to the inner surface of a connecting pipe, and a sealing assembly is arranged between the baffle and the supporting ring. The telescopic rod is movably installed in the linear bearing, meanwhile, one end of the telescopic rod is installed in the reset sleeve and provided with the buffering assembly, the baffle is fixed to the other end of the telescopic rod, and the sealing assembly is arranged between the baffle and the supporting ring fixed to the inner surface of the connecting pipe, so that the telescopic rod can conveniently enable the baffle and the supporting ring to be sealed through the sealing assembly under the action of the buffering assembly.

Description

technical field [0001] The invention belongs to the technical field of check valves, in particular to a magnetic check valve for range hoods and bathroom heaters. Background technique [0002] Range hood check valve is also called reverse flow valve, check valve, back pressure valve, one-way valve, flue valve. The flue valve is a kind of automatic valve that is automatically opened and closed by the force generated by the flow of the medium itself in the pipeline. Its main function is to prevent the medium from flowing back, and it can be applied to pipelines of various media. The flue check valve is installed on the pipeline, which becomes one of the fluid parts of the complete pipeline. The flue check valve, also known as the inner wall hood, is also an environmentally friendly product promoted by the Ministry of Construction. In modern housing construction, it has been widely used. The production of the flue check valve has solved a major problem for the new high-end r...
