Embodiment 1

[0044] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 shown

[0045] An electric valve, including an electric valve body 7, the electric valve body 7 is composed of a first valve body 1 and an electric actuator 2 arranged on the first valve body 1, in this embodiment, the first valve body 1 is a ball valve and an electric actuator 2 is arranged on the first valve body 1 , and the two are combined to form an electric ball valve. The first valve body 1 is provided with a first water inlet 10 and a first water outlet 11 .

[0046] The electric actuator 2 includes a power actuator 8 and an electronic controller 9. The electronic controller 9 includes an internal microelectronic control module 90 and a control panel 91 arranged on its outer surface. The microelectronic control module 90 is connected to the control panel 91 And the rated control parameters of the microelectronic control module ...

Embodiment 2

[0054] In this embodiment, the microelectronic control module 90 also includes an alarm circuit ( Figure 18 shown) or / wireless transmission control line ( Figure 19 shown), others are the same as in Embodiment 1, and will not be repeated here.

Embodiment 3

[0056] Such as Figure 20 , Figure 21 , Figure 22 , Figure 23 and Figure 24 As shown, a water leakage protection device includes a water flow sensor 6 and the electric valve body 7 described in Embodiment 1. The water flow sensor 6 is an impeller type water flow sensor, mainly composed of a second valve body 60 and a The water flow rotor assembly 61 in the inner cavity of the second valve body 60 and the Hall sensor 62 arranged outside the second valve body 60, the Hall sensor 62 is connected to the electronic controller 9, and converts the dynamic change of the water flow into a pulse signal After being fed back to the electronic controller 9 and received by its internal microelectronic control module 90, at least two design functions are achieved: the setting and Control, once the upper limit of one of the set rated parameters is touched, it is considered that the water is abnormal, and the water flow control signal is immediately generated and output to the power ac...

Abstract

The invention discloses an electric valve, and particularly relates to an electric ball valve with the function of a check valve arranged in an inner cavity of a water outlet. Under the situation thatthe check valve can be closed normally, a normally-opened micro-leakage through hole is formed in the middle of the check valve, and water slightly leaking from the middle of the check valve can be intensively jetted out from a water jetting hole in a cylindrical body in the middle of the check valve when the electric ball valve is opened; a water leakage protection device comprises the electricball valve and an impeller type water flow sensor, the water outlet of the electric ball valve and a water inlet of the impeller type water flow sensor are connected through an octagonal cap, the tailend of the cylindrical body with the water jetting hole in the water outlet of the electric ball valve extends into the water inlet of the impeller type water flow sensor and is close to the outer edge of an impeller in a cavity of the impeller type water flow sensor as much as possible, thus a water flow jetted out from the water jetting hole of the electric ball valve can push the impeller in the cavity of the impeller type water flow sensor, accordingly micro-leakage of a water pipe can be sensed, a pulse signal can be generated to be output to an electric actuator in the electric ball valve, the electric ball valve is closed immediately, and the purpose of water leakage protection is achieved.

Description

technical field [0001] The invention belongs to the technical field of fluid control, and in particular relates to an electric valve and a water leakage protection device. Background technique [0002] In daily life, water pipe leakage often occurs due to aging water pipes or loose pipe joints. Since water pipes are buried underground, on walls or ceilings, the above-mentioned leakage is not easy to be found. This will not only cause waste of water resources, increase water costs, but also cause Hazardous buildings lead to home destruction and property damage. [0003] In response to the above problems, the Chinese invention patent application (application number: 201610427351.X) discloses a smart water meter with a water leakage monitoring function, including a water meter body on which a controller, a solenoid valve, a water inlet pipe, and a water outlet pipe are arranged. , the water inlet pipe is provided with a one-way valve with a rated pressure difference, and an au...
