Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
In the present embodiment
Referring to fig. 1-2, a manual valve with good tightness comprises a valve body, wherein a manual valve body 10 is connected to the bottom of the valve body through threads, a sealing ring is arranged between the manual valve body 10 and the valve body, a manual valve outer nut 1 is connected to the manual valve body 10 through threads, a manual valve outer nut gasket 3 is further arranged on the manual valve outer nut 1, a manual valve outer four-corner bolt 6 is arranged in the manual valve body 10, and a manual valve sleeve 11 is connected with an inner hexagon of the manual valve body 10 through an outer hexagon to limit the vertical movement of the manual valve sleeve 11.
A Y-shaped sealing ring 4 of the outer nut of the manual valve is arranged between the outer nut 1 of the manual valve and the valve body, and an outer anti-disassembly ring 5 of the manual valve is arranged below the outer nut 1 of the manual valve.
A manual valve outer four-corner bolt large gasket 7 is arranged between the manual valve outer four-corner bolt 6 and the manual valve body 10, a manual valve outer nut gasket 3 is arranged between the lower end face of the quadrangular prism of the manual valve outer four-corner bolt 6 and the manual valve outer nut 1, and the vertical movement of the manual valve outer four-corner bolt 6 is limited by arranging the manual valve outer four-corner bolt large gasket 7 and the manual valve outer nut gasket 3.
A manual valve outer nut sealing ring 2 is arranged between the outer surface of the manual valve outer four-corner bolt 6 and the manual valve outer nut 1.
The upper end face of the middle cylindrical section of the manual valve outer four-corner bolt 6 is respectively provided with a manual valve outer four-corner bolt small gasket 8 and a manual valve outer four-corner bolt sealing ring 9.
The manual valve outer four-corner bolt 6 is connected with a manual valve sleeve 11 through threads, and the manual valve sleeve 11 is connected with a manual valve inner nut 13 through threads.
A manual valve plastic plug 12 is arranged in the manual valve inner nut 13.
Working principle: in the use process of the manual valve, the manual air release valve is in a normally closed state, and the manual air release valve is opened only when the electromagnetic valve is damaged to realize the air release function. The manual maintenance valve is in a normally open state, and the manual maintenance valve blocks the gas-blocking path after being closed, so that the sub-valves such as the gas inlet and outlet pipelines can be disassembled.
The manual valve body 10 is fixed with the manual valve outer nut 1, and the vertical movement of the manual valve outer four-corner bolt 6 is limited by the manual valve outer four-corner bolt large gasket 7 and the manual valve outer nut gasket 3, and the manual valve outer four-corner bolt 6 is connected with the manual valve sleeve 11 through threads.
