Embodiment Construction

[0037] refer to Figure 1 to Figure 9 The embodiments of the present invention will be further described.

[0038] The novel valve described in this embodiment, such as figure 1 As shown, it includes a valve body 1, the valve body 1 includes a valve cover 2, the valve body 1 has a water inlet channel 11, a water outlet channel 12 and a valve cavity for installing a valve core 3, and the valve core 3 is used to communicate with the valve body 1 The valve seat interferes to block the water inlet channel 11 and the water outlet channel 12. The valve core 3 includes an elastic member and is always in contact with the valve seat by means of the elastic member. The elastic member in the prior art uses a spring 33, and the spring 33 is also used in this embodiment. , for convenience. An elastic diaphragm 31 is also connected between the valve core 3 and the inner wall of the valve cavity, and the elastic diaphragm 31 separates the valve cavity into an upper cavity 13 and a lower ca...

Abstract

The invention discloses a novel valve. The novel valve comprises a valve body which comprises a valve bonnet and is provided with a water inlet channel, a water outlet channel and a valve cavity for mounting of a valve core. The valve core is used for abutting against a valve seat in the valve body to block the water inlet channel and the water outlet channel. The valve core comprises an elastic part and abuts against the valve seat by the aid of the elastic part throughout. An elastic membrane is further connected between the valve core and the inner wall of the valve cavity and divides the valve cavity into an upper cavity body and a lower cavity body. An auxiliary opening device is further arranged on the valve body and comprises an auxiliary valve cavity formed in the valve body. A pulling part for pulling the valve core is arranged in the auxiliary valve cavity and connected with the valve core. The pulling part is driven by fluid entering the auxiliary valve cavity. The novel valve further comprises a switching assembly. A main water inlet way is arranged between the water inlet channel and the switching assembly. The switching assembly is used for controlling water inlet of the auxiliary valve cavity and water outlet of the upper cavity body, or water inlet of the upper cavity body and water outlet of the auxiliary valve cavity. By means of the novel valve, low-pressure opening can be achieved, and energy consumption of an irrigation system is lowered.

Description

technical field [0001] The present invention relates to a valve, more specifically it relates to an agricultural irrigation valve. Background technique [0002] Agricultural irrigation valves are widely used in large-scale agricultural irrigation, and the valve mainly plays the role of on-off of multiple irrigation pipelines. [0003] In the prior art, the applicant’s recent patent document with application number 201520091060.9 discloses a valve using a valve switch assembly, including a valve body with an inner cavity, and a water inlet channel and an outlet channel are opened in the valve body , the inner cavity is provided with a movable elastic diaphragm, and the elastic diaphragm divides the inner cavity into an upper cavity and a lower cavity, and the valve body also includes a valve switch assembly and a mounting base. The installation base is provided with the water inlet and outlet of the upper cavity, the water inlet and the emptying port of the upper cavity, and...
