Method for making siphon type intermittent water supply device overcome gas blockage

Abstract

The invention belongs to the technical field of agricultural water-saving irrigation, and particularly relates to a method for making a siphon type intermittent water supply device overcome gas blockage. The siphon type intermittent water supply device comprises a water storage container, a water supply pipe, a siphon pipe, a water injection auxiliary pipe, a check valve and a dustproof elbow pipe. One end of the siphon pipe is arranged in the water storage container, and the other end of the siphon pipe downwards penetrates through the water storage container. The siphon type intermittent water supply device is characterized in that after downwards penetrating through the water storage container, the other end of the siphon pipe is divided into two routes, one route is downwards connected with a pressure control irrigation emitter, the other route is upwards connected with the lower end of the check valve through the water injection auxiliary pipe, and the check valve is higher than the water storage container. When the water outlet end of the siphon pipe of the siphon type intermittent water supply device is not opened and for instance connected with the pressure control irrigation emitter, gas blockage can be effectively overcome, the water injection process is smoothly completed, rapid and reliable siphon is formed, and finally the expected intermittent water supply function is achieved; meanwhile, the siphon type intermittent water supply device keeps the advantages of being simple in structure and free of maintenance and adjustment.

Description

Technical field: [0001] The invention belongs to the technical field of agricultural water-saving irrigation, and in particular relates to a method for overcoming air blockage of a siphon type intermittent water supply device. Background technique: [0002] The siphon intermittent water supply device is widely used because of its simple structure and no need for maintenance and adjustment. However, when the water outlet end of the siphon pipe of the siphon intermittent water supply device is not open or the water outlet end of the siphon pipe is not connected to an open sump, for example, if it is connected to a "pressure-controlled sprinkler", there is an "air blockage" problem. If the water filling process cannot be completed smoothly, a fast and reliable siphon cannot be formed, and finally the expected intermittent water supply function cannot be realized. Invention content: [0003] The purpose of the present invention is to provide a method for overcoming air blocka...
