Ultra-high pressure one-way valve device

Abstract

The invention discloses an ultra-high pressure one-way valve device. The ultra-high pressure one-way valve device comprises a shell formed by an outer wire connector main body and an inner wire connector main body and a valve body formed by a semi-circular arc solid coaxial body, a grid-shaped hollow coaxial body and an elastic piece. Through unique design of the two-piece valve body, combining the arc solid coaxial body and the thick-wall hollow coaxial body with a plurality of annual through holes under the effect of tension connection of a spring, perfect combination and integrated evolution are carried out to form a valve core body, so that the problem that a traditional one-way valve can only be vertically installed is solved. The ultra-high pressure one-way valve device not only canbe installed horizontally, but also can be installed vertically; and the problem that the traditional one-way valve cannot be used on a high-pressure pipeline or cannot achieve the effect of the one-way valve on the high-pressure pipeline due to the structural defects is solved.

Description

technical field [0001] The invention relates to a one-way valve, and more specifically, relates to an ultra-high pressure one-way valve device. Background technique [0002] In the hot-dip galvanizing production area of ​​cold rolling mills of many iron and steel enterprises, the high-pressure washing system equipment of the temper mill is an important equipment for the production of high-end automobile sheets and home appliance sheets. Impurities such as zinc particles and zinc powder on the surface, when these galvanized sheets adhered to zinc particles and zinc powder are rolled by a temper mill, these impurities that originally adhered to the galvanized sheet will adhere to the work rolls Surface and back-up roll surface, after a long time will cause more and more impurities on the work roll and back-up roll surface, zinc particles and zinc powder on the plate surface will seriously affect the quality of galvanized sheet products. [0003] At present, most of the temper...

Problems solved by technology

[0004] 1). From the perspective of its structure, the back of the valve cone spool relies on a spring to maintain the buffering effect of the cone spool when it is opened and closed, and this spring has no guide or vertical device to maintain the spring and the cone spool. If it is used on a high-pressure medium pipeline, the check valve spool will be displaced or tilted when the check valve spool is in a high-pressure state when it is loaded [working state] or unloaded [bypass state], thus losing the ability to maintain the opening and closing of the cone spool. Buffer effect, further causing the failure of the one-way valve function

[0005] 2). Since the one-way valve relies on the self-weight of the spool to close the medium, the key is that when the pressure medium lifts the spool, since the spool is cylindrical, this will inevitably affect the pressure medium passing through the one-way valve to a certain extent. The flow rate affects the water outlet pressure when the nozzle of the high-pressure water gun is working;

[0006] 3). When the valve is working normally, because the valve core is in the open state for a long time, the diversion groove on the back of the valve core is closely attached to the valve body for a long time. As time goes by, the diversion groove on the back of the valve core is pressed and deformed, resulting in The arc surface of the open spool is tilted, causing the flow to be unstable;

[0007] 4). Since the valve body of the valve is a whole, the valve core is blocked and fixed by the gland on the end face of the valve body, so once the valve core is found to be damaged and the function fails, it will not be possible to repair and replace the valve core, only the entire valve body can be replaced , and due to the structural characteristics of the valve, it can only be installed vertically up and down, and cannot be installed horizontally.
