Novel damper

Abstract

A new type of damper, the invention relates to the technical field of dampers; it includes a cylinder body, a flow valve seat assembly, a valve stem, and a sealing seat; the inside of the cylinder body is provided with a flow valve seat assembly, and the inner end of the valve stem It is connected and fixed with the flow valve seat assembly, and its outer end is set outside the cylinder body after passing through the sealing seat; the sealing seat is slidably sleeved on the valve stem, and communicates with the outside world through the Y-shaped lip on the inner wall of the sealing seat; The flow valve seat assembly is a type A flow valve seat assembly, which is composed of a type A flow valve seat and a damping sleeve; the damping sleeve is sleeved on one end of the A type flow valve seat; the valve stem passes through it The corrugated connecting end at the inner end is clamped and fixed with the other end of the A-type flow valve seat. It is small in size, large in energy absorption, high in damping effect, and uses air as the working medium. It has the advantages of cleanliness, pollution-free, long-term use without maintenance, etc., and is more practical.

Description

technical field [0001] The invention relates to the technical field of dampers, in particular to a novel damper. Background technique [0002] The buffer damper is a buffer device that uses damping characteristics to slow down mechanical vibration and consume kinetic energy. It is widely used in various joints such as guide rails and hinges, so as to reduce the noise generated during the use of the joints. Among them, hydraulic buffer dampers are mostly used. [0003] The working principle of the hydraulic buffer damper is mainly through the back-and-forth transmission of the internal hydraulic oil on both sides of the flow valve seat assembly, which reduces the sliding speed of the flow valve seat assembly, so as to slow down the sliding speed of the movable parts of the connecting parts and reduce the time required for the movement of the connecting parts. purpose of the noise generated.

Problems solved by technology

[0004] However, the hydraulic oil is difficult to compress, making it difficult to reduce the volume of the hydraulic buffer damper

Moreover, the valve stem is connected to the flow valve seat assembly in the existing hydraulic buffer damper. When the valve stem enters the buffer cylinder, the volume of the valve stem will push the hydraulic oil out of the cylinder, which is difficult to clean and pollutes the environment.

When the valve stem is pulled out, the air outside the cylinder will enter the cylinder, so the buffer cylinder cannot be completely filled with hydraulic oil.

Also, the presence of air in the cylinder can cause noise when the damper opens or closes

Therefore, the long-term use of the hydraulic buffer damper needs to be overhauled or replaced, which seriously affects the normal use of the product
