Embodiment Construction

[0018] The noiseless check valve for small hot water boilers of the present invention is specifically described as inserting the left side gasket 12a close to the inner surface of the central through hole of the left side wall 11 of the cylindrical body 10 and inserting it toward the valve disc. The spring 14 on the inner surface of the strip-shaped protrusion 13 protruding from the right side of the edge of 12 is sleeved on the left side of the central through hole of the support disc 15 attached to the middle wedging end 10a of the inner surface of the open part on the right side of the cylinder 10 Formed in the circular band groove 15a, so that the valve disc 12 has an elastic valve switch device, a vertical flange 16 protrudes at a certain height from the right end of the outer surface of the cylinder body 10, and the vertical flange 16 As the center, on the left side, the upper end of the vertical flange 16 can be close to the diameter of the inner surface and the certain ...

Abstract

The invention relates to a check valve for a small sized hot-water boiler capable of preventing noise. A left inner tube and a left outer tube are arranged around the left outside of a cylindrical body as a double layer surrounding structure with a certain interval. The water of water tank passes between the outer surface of the left inner tube and the inner surface of the left outer tube, and circulates like a ''z'' character between the inner surface of the left inner tube and the outer surface of the check valve cylindrical body. A right inner tube and a right outer tube are arranged around the right side of the cylindrical body as a double layer surrounding structure with a certain interval. The fast expand hot water which is heated by a heater cylinder passes between the outer surface of an inward tube connection opening in the right outer tube center and the inner surface of the right inner tube, and circulates like a ''z'' character between the outer surface of the right inner tube and the inner surface of the cylindrical body, thereby minimizing the circulation pressure of the water from the water tank and the hot water from the heater heater cylinder and forming a double water layers, and preventing the opening and closing noise in the check valve from speading outward.

Description

technical field [0001] The invention relates to a noiseless check valve for a small hot water boiler, which is used for heating equipment that utilizes a heater cylindrical tube to thermally expand hot water to circulate hot water, and can prevent the check valve from frequently starting back and forth due to the thermal expansion of hot water The noise generated when the valve is switched. Background technique [0002] In the heating equipment that heats the water in the water tank through the heater cylindrical tube and utilizes the thermal expansion of the hot water to circulate the hot water, in order to prevent the rapidly expanding hot water from flowing back into the water tank, the inlet of the heater cylindrical tube A check valve is installed, however, due to the thermal expansion of hot water, the check valve is frequently activated, causing excessive noise when the valve is switched back and forth. Contents of the invention [0003] The thermal expansion press...
