Detailed Description

Referring to fig. 1-3, a detachable plastic check valve includes a valve body 1, both ends of the valve body 1 are provided with a connecting ring 2, an inner cavity 3 is provided inside the valve body 1, an inner wall of the inner cavity 3 is provided with an antibacterial layer 4, a top end of the valve body 1 is connected with a connecting block 5, both sides of the connecting block 5 are connected with a connecting bolt 6, a sealing gasket 7 is provided inside the valve body 1 at the bottom end of the connecting block 5, an installation layer 8 is provided at the bottom end of the sealing gasket 7, a threaded hole 15 matched with the connecting bolt 6 is provided inside the installation layer 8, a rotating shaft 9 is provided inside the valve body 1, a spring 14 is sleeved outside the rotating shaft 9, one end of the spring 14 is connected with a valve core 10, a pressing block 11 is provided at one side of the valve core 10.

The utility model discloses a valve body 1, clamping ring 2, inner chamber 3, antibiotic layer 4 and heat preservation 12 that set up have realized that the check valve comprises the plastics material, and the heat conduction condition of plastics is relatively poor, can not scald user's hand among the hot water system, also can fall to heat energy consumption minimum in hot water storage pipeline for hot water has better heat preservation effect.

Please refer to fig. 2, the number of the connecting rings 2 is two, the inner threads are disposed inside the two groups of connecting rings 2, and the two groups of connecting rings 2 are made of metal material, which can ensure that the connecting rings 2 are not damaged when connected with the pipeline, so that the service life of the check valve is prolonged.

Please refer to fig. 3, the number of the connecting bolts 6 is four, the four sets of connecting bolts 6 are symmetrically arranged about the longitudinal central axis of the connecting block 5, and the connecting bolts 6 can connect the connecting block 5 and the valve body 1 for easy installation and disassembly.

Please refer to fig. 1, the inside of the sealing gasket 7 is provided with four sets of through holes, the four sets of through holes are matched with the connecting bolt 6, the sealing gasket 7 is made of rubber material, the sealing gasket 7 is detachably connected with the valve body 1, and the sealing gasket 7 can enable the connecting block 5 and the valve body 1 to be tightly connected to avoid water leakage.
