Problems solved by technology

When the quick-change joint is connected, the two valve core parts in the female joint and the male joint contact through the flat end surface. Under the action of the pulsating fluid, the valve core part is guided only by the matching gap between the valve core part and the valve seat, causing the valve core part to The work is unstable, and it is easy to produce radial deviation, which will cause the joint to be unstable and damage the rubber sealing ring of the valve core part; when the quick-change joint is disconnected, the working medium will be damaged due to the damage of the rubber sealing ring of the valve core part. leakage of

Abstract

The invention provides a hydraulic quick connecting device comprising joint parts and valve element parts. The joint parts comprise a male joint and a female joint. The valve element parts comprise avalve seat, a spring, a gland and a valve element part rubber seal ring. The spring is located between the valve seat and the gland, the valve element part rubber seal ring can be respectively in contact seal with the inner conical surfaces of the male joint and the female joint under the elastic force of the spring, a blind hole is formed in one end surface where two valve element parts contact,and a boss short shaft matched with the blind hole is arranged on the other end surface. According to the hydraulic quick connecting device, the blind hole is formed in the male joint valve element part, and the female joint valve element part is provided with the boss short shaft. When the female joint and the male joint are communicated, the boss short shaft is inserted into the blind hole to ensure that the valve element part of a quick change joint is not staggered under the pulsating pressure, and does not generate offset in the radial direction, so that the stability of the valve elementis ensured after the connection, and the working stability of the connected quick change joint is ensured accordingly.

Description

technical field [0001] The invention relates to the field of hydraulic technology, in particular to a hydraulic quick connection device. Background technique [0002] At present, the hydraulic quick-connect device used in the hydraulic pneumatic pipeline system has a flat end face at the top of the valve core component. When the quick-change joint is turned on, the two valve core parts in the female joint and the male joint contact through the flat end faces. Under the action of the pulsating fluid, the valve core parts are guided only by the matching gap between the valve core parts and the valve seat, resulting in the valve core parts. The work is unstable, and it is easy to produce radial deviation, which will cause unstable overcurrent of the joint, which will damage the rubber sealing ring of the valve core part; when the quick-change joint is disconnected, due to the damage of the rubber sealing ring of the valve core part, the working medium will be damaged. of exter...
