Abstract
The utility model discloses a three-position four-way air-controlling reversing valve, which belongs to the field of mechanical manufacture. A return spring of the reversing valve is arranged on one side of an end cover, so that an air cylinder body is easy for processing, the air cylinder body is in a square structure; a spring around a valve rod in the air cylinder is thickened; a positioning sleeve of the air cylinder body is separated from the air cylinder body; and a travel adjusting bolt is arranged at the top of the air cylinder body and is used for controlling the descending speed. The utility model can be controlled by an air signal and is suitable for places at which power supplies are not allowed to exist; the return spring is positioned on one side of the end cover, so that the air cylinder body is easy for processing and the work efficiency is improved; the section of the air cylinder is increased and the spring force is increased, so that the reversing and returning are quick and the reliable performance of the system can be improved; and the adjusting bolt is arranged at the air cylinder body part, so that the opening degree of a valve port and the descending speed can be adjusted and the application range is wider.
Description
Technical field
The utility model belongs to mechanical manufacturing field, relates to a kind of hoisting system.
Background technique
Selector valve mainly contains automatically controlled and gas control, and what use in the market mainly is Pneumatic reversal valve, and following defective is arranged on such product structure: 1, return spring is in cylinder block one side, and the cylinder block difficulty of processing is big, and efficient is low.2, the cylinder portion sectional area is little, and spring force is little, and the commutation return time is long, and system easily glides.3, valve port opening is fixed, and rate of descent is non-adjustable, and Applicable scope is little.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of novel 3-position 4-way Pneumatic reversal valve, is provided with unreasonable to solve the prior art structure, the processing technology complexity, difficulty is big, and efficient is low, defectives such as the commutation return time is long, and system easily glides, and the lifting rate of descent is non-adjustable.
The utility model mainly is made up of end cap, safe spool, valve body, cylinder block, piston, solves the technological scheme that its problem adopts to be; Return spring is in end cap one side, and cylinder block is easily processed; Cylinder block is a square structure, spring overstriking around the cylinder block inner valve stem, and the cylinder block setting sleeve separates setting with cylinder block; At the cylinder block top stroke adjustment bolt is set, is used to control rate of descent.
Adopting good effect of the present utility model is with the control of gas signal, is applicable to the place that does not allow power supply to exist; Return spring is in end cap one side, and cylinder block is easily processed, and raises the efficiency; The cylinder sectional area strengthens, and spring force strengthens, and the commutation return is rapid, improves the system reliability energy; Cylinder block is partly established the adjustment bolt, and valve port opening is adjustable, and rate of descent is adjustable, and Applicable scope is bigger.
