Problems solved by technology

The existing high-pressure discharge valve has the following disadvantages: the commonly used high-pressure discharge valve is sealed by a hard ball in the center and a soft surface, and is sealed by a tight fit seal. Under high pressure, if it is opened instantly, it is easy to cause the ball and The soft sealing surface is damaged by high-pressure impact, causing the machine to fail to work normally

Embodiment

[0017] When working, turn the handwheel 8 counterclockwise, and the handwheel 8 will drive the discharge valve screw 5 to rotate in the opposite direction to the discharge valve body 11, that is, the high-pressure discharge valve is opened, and the high-pressure material passes through the center hole of the base 1, pushing the ceramic ball 3 and fixing the ceramic ball The rod 4 is pushed away from the base 1, and air or other substances will be discharged from the machine body through the side hole 13 of the discharge valve body 11. After the air or other substances are exhausted, turn the hand wheel 8 clockwise to drive the discharge valve screw 5 to rotate in, and the discharge valve screw 5 pushes the ceramic ball fixing rod 4 and the ceramic ball 3 to move to the base 1 until the ceramic ball 3 is in contact with the base 1 The arc surfaces of the valves match and press tightly, that is, the discharge valve is closed. The circlip 6 controls the loosening distance of the ...

Abstract

The invention relates to the technical field of high-pressure airless spraying equipment. A common high-pressure exhaust valve is sealed by a central metal ball and a soft face in a contacted mode, the tight fit sealing mode is adopted for sealing, under the action of high pressure, the metal ball and the soft sealing face are prone to being damaged by high-pressure cutting when the high-pressure exhaust valve is opened instantly, and consequently a machine cannot work normally. A high-pressure exhaust valve for a high-pressure airless sprayer is provided by the invention and is characterized in that the high-pressure exhaust valve for the high-pressure airless sprayer comprises an exhaust valve body and a hand wheel; the exhaust valve body comprises a base, an exhaust valve bush, a ceramic ball, a ceramic ball fixing rod, an exhaust valve screw, a clamp spring and sealing rings; the base, the ceramic ball, the ceramic ball fixing rod and the exhaust valve screw are arranged in the exhaust valve bush; and the base is in interference fit with an end hole of the exhaust valve bush. The sprayer high-pressure exhaust valve which is high in high-pressure bearing capacity, not liable to be blocked, long in service life and easy to machine is designed by modifying traditional air exhaust valve structures.

Description

technical field [0001] The invention relates to the technical field of high-pressure airless spraying machine equipment, in particular to a high-pressure discharge valve for a high-pressure airless spraying machine. Background technique [0002] The high-pressure airless sprayer uses the high-pressure discharge valve to discharge the air in the high-pressure sprayer or the high-pressure liquid accumulated inside the machine, so that there is no air in the high-pressure airless sprayer to ensure the normal operation of the machine. The existing high-pressure airless spraying machine adopts the traditional quick-opening ball valve as the high-pressure discharge valve. The ball valve uses a ball with a circular through hole in the center as the opening and closing part, and the ball rotates with the valve stem to realize the opening and closing action of the valve. . The opening and closing part of the ball valve is a ball with a hole, which rotates around the axis perpendicul...
