[ detailed description ] embodiments

The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to fig. 1-2. It is to be understood that the described embodiments are merely exemplary of the utility model, and not restrictive of the full scope of the utility model. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

As shown in fig. 1, the pneumatic control leaf type water valve provided by the utility model comprises a valve body 1 and a valve cover 5 connected with the valve body 1. The valve body 1 is provided with a cavity, the side surface corresponding to the cavity is provided with a water outlet, and the water outlet is communicated with the cavity. A water inlet vertical to the cavity is arranged above the cavity, and an internal thread is arranged at the end part of the water inlet and used for connecting a water pipe. The water inlet is communicated with the chamber through a flow channel which is vertical to the chamber, and the upper end of the flow channel is provided with a plug 10. The valve sleeve 2 is arranged in the cavity, and the front end and the rear end of the valve sleeve 2 are respectively provided with a sealing ring 8, so that the valve sleeve 2 is hermetically arranged in the cavity. A valve core 3 is arranged in the valve sleeve 2, one end of the valve core 3 is connected with a cylinder 4, the valve core 3 is driven by the back-and-forth movement of the cylinder 4 to slide in the cavity, and the other end of the cylinder 4 extends into the valve cover 5. A reset spring 6 is arranged in the valve cover 5, one end of the reset spring 6 is abutted against the cylinder 4, and the other end of the reset spring 6 is abutted against the inner wall of the valve cover 5. A guide seat 9 is arranged between the cylinder 4 and the reset spring 6, a concave through hole is arranged in the middle of the guide seat 9, and a boss matched with the concave through hole of the guide seat 9 is arranged at one end, extending into the valve cover 5, of the cylinder 4. Under the action of the return spring 6, the guide seat 9 pushes the cylinder 4 to move back and forth. An air inlet is arranged at the upper end of the valve cover 5.

Example 2

As shown in fig. 2, most of the structures of this embodiment are the same as those of embodiment 1, and the description of the same parts is omitted. The difference between this embodiment and embodiment 1 is that a water inlet channel perpendicular to the chamber is disposed above the chamber, and the water inlet channel penetrates through two sides of the whole valve body 1. And internal threads are arranged at two ends of the water inlet channel and are used for connecting the water pipe and the end plug. The valve body 1 is provided with 4 connecting holes 7 which are transversely communicated, and bolts penetrate through the connecting holes 7 to realize the series connection of the valve bodies 1.
