Detailed Description

The technical contents of the preferred embodiments of the present invention will be more clearly understood and appreciated by referring to the drawings attached to the specification. The present invention may be embodied in many different forms of embodiments, and the scope of the invention is not limited to the embodiments described herein.

Fig. 1 is a perspective view of a pipe joint with an automatic water discharge valve in a preferred embodiment of the present invention. It can be seen that the pipe joint 1 is provided with a drain opening 2 in the pipe wall. The water contained in the hose connected to the pipe joint 1 can be discharged from the discharge port 2.

Fig. 2 and 3 are cross-sectional views of the pipe joint of fig. 1. As can be seen from the figure, the valve body 3 of the automatic water discharge valve, on which the water discharge opening 2 is provided, is mounted on a threaded through hole 12 in the pipe wall of the pipe joint 1 by means of threads 4 and extends into the flow passage 12 in the pipe joint 1. The valve body 3 comprises a water inlet 9 communicating with a flow passage 12. The valve core 6 and the turning plate 5 in the valve body 3 are connected. Flap 5 is switchable between a closed position and an open position. When the turning plate 5 is in the closed position as shown in fig. 2, the turning plate 5 is tilted upwards in the flow passage 12 of the pipe joint 1, and the valve core 6 is driven to be in the closed position, so that the water inlet 9 and the water outlet 2 are blocked. When the turning plate 5 is in the opening position as shown in fig. 3, the turning plate 5 is turned and inclined downwards in the flow channel 12 of the pipe joint 1, and the valve core 6 is driven to be in the closing position to conduct the water inlet 9 and the water outlet 2. The valve body 3 is also provided with a first limiting part 7 for limiting the turnover of the turning plate 5 at the opening position; and a second limit portion 8 for limiting the turning of the flap 5 at the closed position.

Fig. 4 and 5 are a perspective view and an assembly view of the automatic water discharge valve. As shown in the figure, the valve core 6 is disposed through the valve core seat hole 14 of the valve body 3, and both ends of the valve core extend out of the valve core seat hole 14. The water inlet 9 is correspondingly arranged on the side wall of the valve core seat hole 14. One end of the turning plate 5 is provided with a shifting fork 13, and two ends of the valve core 6 are respectively provided with a shifting fork fixing groove 10. The turning plate 5 is connected to the valve core 6 through a shifting fork 13 and a turning plate fixing groove 10, and the shifting fork 13 also plays a role in fixing the valve core 6 on the valve body 3. The shifting fork 13 and the flap fixing groove 10 can be connected through fasteners such as bolts and the like, and are also in interference fit. The automatic water discharge valve of the utility model aims to discharge the water stored in the hose connected with the pipe joint, so that sealing elements such as sealing rings are not needed.

As shown in fig. 6-7, when the pipe joint 1 of the present invention is in an operating state, the lower part is connected to the water pump 15, and the upper part is connected to the hose 16. When the water pump 15 starts to work, fluid enters the hose from the flow channel 12 of the pipe joint 1 from bottom to top under the driving of the water pump 15, and the turning plate 5 can be turned upwards by the impact of water flow, so that the valve core 6 is driven to be in a closed position. When the water pump 15 stops working, the turning plate 5 automatically falls back under the action of gravity and turns downwards to an open position, the valve core 6 conducts the water inlet 9 and the water outlet 2, and the stored water in the hose 16 can be automatically discharged through the water outlet 2.

In the above embodiment, the turning plate 5 is set to automatically fall back by gravity, and in other embodiments, a return spring connected to the turning plate can be used to automatically fall back after the water pump stops working and the impact force of the water flow disappears.

The automatic drain valve of the utility model has the advantages of small volume, few components, simple structure and high reliability; the pipe joint can be matched with the original threads of the pipe joint, and is installed by inserting the pipe joint between the outside, so that the installation is simple and the stability is good.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the teachings of this invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
