Abstract

The invention relates to a multifunctional valve and a multifunctional valve combination valve. The multifunctional valve and the multifunctional valve combination valve comprise a valve body, a valve cavity which is arranged in the valve body and a valve rod which is arranged in the valve cavity, wherein a middle inlet, a left inlet and a right inlet are arranged on one side of the valve body, the middle inlet is used for the entering of pressure mediums, the left inlet and the right inlet are used for the selective entering of the pressure mediums, a left outlet and a right outlet are arranged on the other side of the valve body, the left outlet and the right outlet are used for the discharging of the pressure mediums, and the left inlet and the left outlet and the right inlet and the right outlet are selectively communicated in a corresponding mode through the matching of the valve cavity and the valve rod. The multifunctional valve and the multifunctional valve combination valve are characterized in that the left inlet is communicated with a left cavity correspondingly, the right inlet is communicated with a right cavity correspondingly, and correspondingly, the left cavity and the right cavity are communicated with the left outlet and the right outlet through a left throttle valve and a right throttle valve. According to the multifunctional valve and the multifunctional valve combination valve, a piston can be slowly contacted with the end portion of a piston cylinder, the collision and the abrasion to a piston rod when the piston is moved rapidly are avoided, the service life of the piston cylinder is prolonged effectively, and meanwhile the operation safety of the piston cylinder and the stability of the piston cylinder are ensured.

Description

technical field [0001] The invention relates to the technical field of buffer valves and related valve groups. Background technique [0002] When the piston cylinder works at high speed or high pressure, the movement speed of the piston rod and the piston is very fast. In this way, when the piston quickly moves to the two limit positions of the front end and the rear end of the cylinder body, the piston and the end cover of the cylinder body will inevitably be closed. Collision. Not only can it produce a lot of collision noise, but it will inevitably cause serious wear and tear on the piston and the end cover of the cylinder block. After using for a period of time, it will inevitably cause certain damage to the piston and the end cover of the cylinder body; the higher the pressure, the faster the speed, and the shorter the service life of the piston cylinder. Contents of the invention [0003] The primary technical problem to be solved by the present invention is to prov...
