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 As shown in -4, the water volume adjustment rod of the embodiment of the present invention includes a rod body 1, and a central hole 2 extending along the length direction of the rod body 1 is arranged inside the rod body 1. The protruding flange surface 21 separates the central hole 2 into an upper pressure relief hole 22 and a lower adjustment hole 23, and the pressure relief hole 22 and the adjustment hole 23 communicate with each other.

[0020] The pressure relief hole 22 is provided with a pressure relief assembly, which can guide and release pressure from one end of the pressure relief hole 22 when the water pressure in the lower adjustment hole 23 is high. From the flange surface 21 to the end of the central hole 2 , that is, the upper end, a sealing gasket 31 , a pressure relief valve core 32 , a pressure reli...

Abstract

The invention discloses a water volume adjusting rod. The water volume adjusting rod comprises a rod body capable of relatively rotating, and a rotating cover coating the outer side of the lower part of the rod body, wherein a center hole extending in the length direction is formed in the rod body, and comprises an adjusting rod in the lower side; an annular groove surrounding outside the adjusting hole is formed in the end part, corresponding to the adjusting hole, of the rod body to form an inner side peripheral wall and an outer side peripheral wall at intervals; the upper part of the rotating cover and the outer peripheral surface of the rod body are tightly connected; a water inlet hole and a water outlet hole are formed in the peripheral wall of the rotating cover; and multiple corresponding throttle holes are formed in the outer side peripheral wall of the rod body. The adjusting rod can effectively guide and arrange water currents, can effectively prevent high-speed water currents from being directly collided with pipe walls or from being collided with each other in the flowing process, effectively prevents a turbulent state, effectively prevents the noise, and effectively reduces the noise when the flowing speed of the water currents is the highest.

Description

technical field [0001] The invention relates to a water volume regulating mechanism, in particular to a water volume regulating rod used in a water heater. Background technique [0002] A water heater is a product that uses electricity or gas to heat cold water. The main principle is to heat cold water in the water heater through the combustion of gas or the conversion of electrical energy into heat energy. [0003] At present, general gas water heater products are equipped with a water volume adjustment lever at the water outlet to manually adjust the water output. Generally, there is such a problem in the use of the water volume adjustment lever. When the water volume adjustment lever is adjusted from large to small, the flow rate gradually decreases and the noise of the water flow gradually increases. Especially in the state of high water pressure from the outside, the noise is obvious. Increased, even up to 80dB, greatly reducing user experience. Analyze the cause of t...
