Abstract
The utility model relates to a drainage and irrigation flood control apparatus, particularly a square type single side-door full automatic irrigation and drainage flood control valve. The square type single side-door full automatic irrigation and drainage flood control valve is composed of a valve body, a special-shaped flange, an annular groove, an upper hinging ear, a lower hinging ear, an upper shaft pin, a lower shaft pin, a valve plates, etc., wherein the front end face of the valve body is provided with the special-shaped flange, the end face of the special-shaped flange is provided with the annular groove which is used for installing a rubber o-shaped ring and the upper and the lower hinging ears, the upper and the power shaft pins are arranged in the upper and the lower hinging ears, the valve plates are respectively arranged on the upper and the power shaft pins, and the back faces of the valve plates are respectively provided with a reinforcing rib. Since the upper and the lower hinging ears, the upper and the lower shaft pins and the valve plates on the end face of the special-shaped flange are vertically arranged and are inclined a certain angle, the angle of the utility model is 3 DEG, the utility model utilizes the dead weight horizontal component of the valve plates as door closing dynamic force to achieve the purposes of the opening resistance force of the valve plates decrease and automatic close; a valve with such a structure can work without electricity and liquid control and manual operations.
Description
Technical field
The utility model relates to a kind of irrigation and drainage flood protection device, the full-automatic irrigation and drainage antiflood valve of the one-sided gate-type of especially a kind of cubic type.
Background technology
At present, water valve has been developed into the form of structure of Automatic Control by form of structure manual, electronic, pneumatic and the control of surging both at home and abroad, but, for pressure difference-powered form of structure of coming the by-pass valve control valve plate to open and close action that utilize to import and export fluid media (medium), also have only two kinds of diaphragm type and water vat piston types at present.All there are defectives such as complex structure, the medium circulating resistance is big, energy loss is big in these water valves, the characteristic requirement of the irrigation and drainage that are far from suitable flood control.
Summary of the invention
The purpose of this utility model just provides that a kind of design concept is strange, simple and reasonable, running orbit is unique, resistance to water-flow is minimum, move reliable and stablely, sealing effectiveness is good, can save the full-automatic irrigation and drainage antiflood valve of the one-sided gate-type of cubic type of a large amount of energy and manpower and materials.
The technical solution of the utility model is as follows: the full-automatic irrigation and drainage antiflood valve of the one-sided gate-type of a kind of cubic type comprises valve body, special-shaped flange, cannelure, upper and lower hinge ear, upper and lower pivot pin, valve plate and reinforcing rib etc.Wherein, be provided with special-shaped flange, on special-shaped end face of flange, be provided with cannelure and upper and lower hinge ear, in upper and lower hinge ear, be provided with upper and lower pivot pin, on upper and lower pivot pin, valve plate is housed, on the outerplanar of valve plate, be provided with reinforcing rib at the valve body front end.
The utility model is because the upper and lower hinge ear on the special-shaped end face of flange, upper and lower pivot pin and valve plate at special-shaped flange front end from the right-to-left certain angle (3 ° of the utility model) that tilted, so when the pressure medium of body cavity was less than or equal to valve outside back pressure, valve was just closed automatically; When the pressure medium of body cavity during greater than the outside back pressure of valve, valve is promptly opened automatically, need not hand, electricity, gas, hydraulic control system, not manually-operated.

The specific embodiment
As shown in the figure, the full-automatic irrigation and drainage antiflood valve of the one-sided gate-type of a kind of cubic type, comprise valve body 1, special-shaped flange 2, cannelure 3, valve plate 4, upper and lower hinge ear 5, upper and lower pivot pin 6 and reinforcing rib 7 etc., wherein be provided with special-shaped flange 2 at the front end that is positioned at valve body 1, on the end face of special-shaped flange 2, be provided with cannelure 3 and upper and lower hinge ear 5, in upper and lower hinge ear 5, be provided with upper and lower pivot pin 6, on upper and lower pivot pin 6, valve plate 4 has been installed, in the cannelure 3 on special-shaped flange 2 end faces rubber seal has been installed.
Because upper and lower hinge ear 5 and upper and lower pivot pin 6 and valve plate 4 on special-shaped flange 2 end faces, at special-shaped flange 2 front end faces from the right-to-left certain angle (3 ° of the utility model) that tilted, so, when the pressure medium of valve body 1 inner chamber is less than or equal to valve outside back pressure, valve just can be closed automatically, and when the pressure medium of valve body 1 inner chamber during greater than the outside back pressure of valve, valve is promptly opened automatically, need not hand, electricity, gas, hydraulic control system, not manually-operated.
Structure of the present utility model is that design concept is strange, the running orbit uniqueness, and its opening resistance will reduce more than 80% than the opening resistance of present domestic and international all kinds of valves, can save a large amount of energy and manpower and materials, and is good in economic efficiency.
Claims (2)
1, the full-automatic irrigation and drainage antiflood valve of the one-sided gate-type of a kind of cubic type, comprise valve body, special-shaped flange, cannelure, upper and lower hinge ear, upper and lower pivot pin and valve plate, it is characterized in that: be provided with special-shaped flange (2) at valve body (1) front end, on special-shaped flange (2) end face, be provided with cannelure (3) and upper and lower hinge ear (5) that rubber o-ring is installed, in upper and lower hinge ear (5), be provided with upper and lower pivot pin (6), valve plate (4) is housed on upper and lower pivot pin (6), is provided with reinforcing rib (7) at valve plate (4) back side.
