Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
FIG. 2 is a schematic view showing a front view of a feed valve according to the present invention, and FIG. 3 is a schematic view showing a cross-sectional view of the feed valve according to the present invention. The utility model relates to a closestool water inlet valve capable of preventing siphoning, which comprises a valve body 7, wherein a water inlet channel 208, a water outlet channel, a water stopping component 1 and a lifting mechanism are arranged in the valve body 7 and can cut off water flow, an isolation cavity 3 is arranged between the water inlet channel 208 and the water outlet channel, the isolation cavity 3 is fixed at the upper part of the water inlet channel 208, the water outlet channel is L-shaped, the end part of the vertical part of the water outlet channel is movably arranged in the isolation cavity, the end part of the horizontal part of the water outlet channel is connected with the lifting mechanism, a sealing device is arranged between the water outlet channel and the isolation cavity, the lifting mechanism comprises a water stopping rod 6, a buoy connecting rod 8 and an inner buoy 10, the water stopping rod 8 is connected with the water stopping rod 6 and the inner buoy 10, the water stopping rod 6 is connected with the water outlet channel, the inner buoy 10 is arranged in an outer buoy 9 and can move up and down according to the water level change so as to drive the water outlet channel to move in the isolation cavity 3, the water stopping assembly 1 includes an air hole 214 provided at a vertical portion port of the water outlet passage and an air blocking pad 215 provided at an upper portion of the air hole 214 to be engaged with the air hole 214.
The working principle of the utility model is as follows: when water needs to be added into the water storage tank of the toilet, water enters the water tank from the water inlet channel 208 through the isolation cavity 3 and the water outlet channel, because the inner buoy 10 has a certain weight (the certain weight is not limited to the mass of the inner buoy and is only used for explaining the working mode later), the inner buoy cannot move upwards immediately when water exists in the outer buoy 9 at first, but when the water amount in the outer buoy 9 reaches a certain height and continuously rises (the height can be adjusted by arranging the buoy connecting rod), the floating speed of the inner buoy 10 is increased slowly, so that the water outlet channel is driven to move upwards, and at the moment, the water in the water outlet channel flows back, so that the water in the water outlet channel presses the air blocking pad 215 downwards on the air hole 214, which is equivalent to pressing the air blocking pad on the air hole 214 and applying the acting force of the gravity of the water, the closing of water inlet is realized, and the water inlet valve can not carry out siphon backflow, so that the aim of preventing siphon is fulfilled. When the water level in the outer buoy 9 drops, the inner buoy 10 drives the water outlet channel to drop, and in the process of downward movement of the water outlet channel, the air blocking pad 215 covered on the air hole 214 is flushed away by water in the isolation cavity 3, and the water storage tank is filled with water, so that the working process of the water inlet valve is realized.
The vertical part of the water outlet channel is provided with a water inlet, the horizontal part of the water outlet channel is provided with a water outlet, and the position of the water outlet is higher than that of the water inlet. The inlet channel has inlet channel inlet end and inlet channel outlet end, and inlet channel's play water end is connected with the isolation chamber, and inlet channel from bottom to top is water level regulating rod inlet channel and mobile jib inlet channel in proper order, and the inside of water level regulating rod is water level regulating rod inlet channel, and the groove in the outside of water level regulating rod cooperates with the water level regulating rod fixed slot of water level regulating part, realizes the water level in the control closestool water tank. And a noise reduction groove 2 is also arranged on the outer side of the water inlet channel.
When the water inlet valve enters water, the air hole is opened under the action of water flow of the water inlet channel, and when the water inlet valve does not enter water or negative pressure occurs in the water inlet channel, the air hole is closed; the water outlet end of the water outlet channel is higher than the water level of the water tank.
Compared with the anti-siphon mode adopted by the prior art, the anti-siphon method has the advantages that the anti-siphon effect can be better realized.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the utility model.
