Embodiment 1

[0113] Figure 1 to Figure 13 This is Embodiment 1 of the adjustable steady flow valve of the present invention. The adjustable steady flow valve has a valve body 1 , a valve cavity 2 is formed in the valve body 1 . The adjustable steady flow valve also includes an inner ring 3, a sliding sleeve 4, a steady flow spring 5, a pressure bearing plate 6 and a drive mechanism 7. The inner ring 3 is provided with a number of throttle holes 31 on the peripheral surface. 31 extends along the axial direction of the inner ring 3; the water inlet 11 and the water outlet 12 are respectively arranged at both ends of the inner ring 3, the water inlet 11 is communicated with the inner cavity 32 of the inner ring 3, and the orifice 31 connects the The inner cavity 32 is communicated with the water outlet 12; the sliding sleeve 4 is sleeved on the inner ring 3, the sliding sleeve 4 slides along the inner ring 3 and can cover at least a part of the throttle hole 31, and the sliding sleeve 4 is ...

Embodiment 2

[0135] Most of the structure of this embodiment is the same as that of Embodiment 1, and the difference lies in the structure of the telescopic assembly 72 .

[0136] like Figure 15 As shown, the telescopic assembly 72 includes a first magnet 79 and a second magnet 710, the first magnet 79 is fixed to the end of the telescopic rod 73 outside the valve body 1, the first magnet 79 is a permanent magnet; the second magnet 710 is located in the first The magnet 79 is away from one end of the telescopic rod 73 , the magnetic pole of the second magnet 710 is different from that of the first magnet 79 , and the second magnet 710 generates magnetic force by supplying power.

[0137] In this embodiment, the expansion and contraction of the telescopic rod 73 is realized by the change of the magnetic force of the second magnet 710 . When the telescopic rod 73 needs to be stretched out, the second magnet 710 generates a magnetic force by supplying power, the magnetic force between the s...

Abstract

The invention discloses an adjustable steady flow valve, which comprises an inner ring, a sliding sleeve, a pressure bearing plate, a steady flow spring and a driving mechanism. At least a part of the sliding sleeve faces the water outlet to form at least one set of stepped surfaces, and the axial distances from different stepped surfaces to the end surface of the orifice close to the water outlet form different height values; the pressure bearing plate is sleeved on the inner ring , the pressure bearing plate is provided with a pressure bearing surface facing the water inlet; the steady flow spring is set on the sliding sleeve, and the steady flow spring can exert a force on the sliding sleeve and the pressure bearing plate facing the water inlet; the driving mechanism can be driven by the pressure bearing plate The sliding sleeve turns. For the above-mentioned adjustable steady flow valve, the driving mechanism drives the sliding sleeve to rotate through the pressure bearing plate, so that the step surface of the sliding sleeve corresponding to the orifice is changed, so that the area of ​​the sliding sleeve covering the orifice can be changed, thus obtaining different steady flow valves. flow curve.

Description

technical field [0001] The invention relates to an adjustable steady flow valve. Background technique [0002] In the waterway system of the gas water heater, setting the water flow stabilization device can effectively improve the problem of the temperature fluctuation of the hot water caused by the fluctuation of the water flow, and improve the user's experience of using the gas water heater. 5.2.2.4.6 of GB6932-2015 "Household Gas Instant Water Heaters" requires that the water system should be equipped with flow stabilization or flow adjustment devices. [0003] With the continuous increase of high-rise buildings, the water pressure situation of users' homes is becoming more and more complicated. For example, some communities have high water pressure, and some communities have low water pressure. Different water pressures need to be equipped with flow-stabilizing valves of different specifications to achieve better use results. At the same time, water heaters with differ...
