Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Example 1:
as shown in fig. 1, the embodiment discloses a water conservancy control valve, which comprises a three-way valve body, a valve cover 2, a valve seat 3, a limiting sleeve 4 and a moving rod 5; the three valve ports of the three-way valve body are respectively an upper valve port 11, a water inlet 12 and a water outlet 13, the opening of the upper valve port 11 is provided with a valve cover 2, the channel between the water inlet 11 and the water outlet 12 is a medium circulation channel, and the valve seat 3 is arranged in the medium circulation channel; the limiting sleeve 4 is limited in the cavity of the upper valve port 11, one end of the limiting sleeve 4 is connected with the valve cover 2, and the other end of the limiting sleeve 4 faces the valve seat 3; one end of the movable rod 5 penetrates through the valve cover 2 and extends into the limiting sleeve 4, the other end of the movable rod is exposed out of the valve cover 2, and the movable rod 5 is connected with the valve cover 2 in a sliding and sealing mode; a valve core 6 and a valve rod 7 which is coaxially arranged with the moving rod are sequentially arranged on one side, facing the limiting cylinder 4, of the valve seat 3, one end of the valve rod 7 is connected with the valve core 6, and the other end of the valve rod 7 is connected with the bottom of the limiting sleeve 4 in a sliding and sealing mode and extends into the limiting sleeve 4; the outer wall of the limiting sleeve 4 is hermetically connected with the side wall of the cavity of the upper valve port 11 through a fixing plate 8, and a return spring 9 is connected between the fixing plate 8 and the valve core 6; the end face of the movable rod 5 in the limiting sleeve 4 is provided with a first magnetic connector 51, and the end face of the valve rod 7 in the limiting sleeve 5 is provided with a second magnetic connector 71 matched with the first magnetic connector 51; the bottom of the valve core 6 is connected with a push plate 61 capable of sealing the valve seat.
The first magnetic connector 51 and the second magnetic connector 71 are both electromagnetic chucks, the connection line of the first magnetic connector 51 is connected with the first connection line of the power supply, and the connection line of the second magnetic connector 71 is connected with the second connection line of the power supply.
After the first magnetic connector 51 and the second magnetic connector 71 are energized, the first magnetic connector 51 and the second magnetic connector 71 have the same magnetism.
The first magnetic connector 51 and the second magnetic connector 71 have the same magnetism, and after being magnetically connected, the valve seat 3 can be controlled to open and close by sliding the movable rod 5 up and down.
The limiting sleeve 4 is a hollow sleeve with two closed ends, and flanges are respectively arranged at the port 12 of the water inlet and the port 13 of the water outlet.
The upper valve port 11 is connected with the valve cover 2 through bolts.
The push plate 61 has a diameter equal to the inner diameter of the valve seat 3.
The movable rod 5 is an iron rod body, and the outer diameter of the movable rod 5 is equal to that of the valve rod 7.
The central axes of the upper valve port 11, the moving rod 5, the limiting sleeve 4 and the valve rod 7 are superposed.
The diameter of the valve core 6 is larger than the inner diameter of the valve seat 3.
The sealing ring 10 is an "O" shaped sealing ring.
The working principle is as follows:
the water source enters the three-way valve body through the flange, the water pressure rises along with the increase of the water amount in the medium circulation channel, the water pushes the push plate 61 to move upwards, and the push plate 61 drives the valve core 6 and the valve rod 7 to move upwards. At this time, the return spring 7 in the natural state is pressed. When the water entering the medium flowing channel from the water inlet 12 is gradually reduced, the water pressure is reduced, and the acting force of the water on the push plate 61 is smaller than the restoring force generated by the extrusion of the return spring 7. The return spring 7 drives the valve core 6 and the valve rod 7 to move downwards. Because the diameter of the valve core 6 is larger than the inner diameter of the valve seat 3, the valve core 6 completely covers the valve seat 3, and the valve seat 3 is closed, thereby preventing the water in the three-way valve body from overflowing into the water outlet 13. In addition, the outer diameter of the push plate 61 is equal to the inner diameter of the valve seat 3, and the sealing effect between the valve core 6 and the valve seat 3 is further enhanced.
When the water pressure is too high due to excessive water source or the valve needs to be closed at any time, the water flow of the water source can be controlled by the water utilization control valve in the embodiment. Specifically, after the first magnetic connector 51 and the second magnetic connector 71 are energized, the magnetic properties of the first magnetic connector 51 and the second magnetic connector 71 are different, the first magnetic connector 51 and the second magnetic connector 71 are magnetically connected, and the movable rod 5 moves up and down along the cavity of the limiting cylinder 4, thereby controlling the opening and closing of the valve seat 3. When the water pressure in the water source returns to normal, the first magnetic connector 51 and the second magnetic connector 71 which are connected with the first magnetic connector 51 and the second magnetic connector 71 are disconnected, and the hydraulic control valve returns to the original state.
The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
