Technical Field

The utility model relates to a dry quick-witted technical field of inhaling specifically is a valve unit and dry machine of inhaling thereof advance.

Background

The absorption dryer is named as an adsorption dryer, and the principle of the absorption dryer is that saturated compressed air is filtered by a special molecular sieve for gas purification by utilizing the difference of moisture and air molecular volume, water molecules can be easily absorbed in molecular sieve particles, the molecular sieve is reduced by a regeneration method, and the dew point of the compressed air can easily reach-40 ℃.

The adsorption dryer achieves the drying effect by pressure change (pressure swing adsorption principle). Since the capacity of air to hold water vapor is inversely proportional to the pressure, a part of the air (called regeneration air) after drying is decompressed and expanded to the atmospheric pressure, the expanded air becomes drier due to the pressure change, then the expanded air flows through a drying agent layer (namely a drying tower which absorbs enough water vapor) to be regenerated, which is not communicated with the air flow, and the dried regeneration air sucks out the moisture in the drying agent and carries the moisture out of the dryer to achieve the purpose of dehumidification. The two towers work circularly, do not need a heat source, and continuously provide dry compressed air for a user air system.

The general adsorption type compressed air dryer is of a double-cavity structure, when one cavity works during air inlet, the other cavity regenerates, regenerated waste gas is discharged from a discharge valve of the cavity, and the two cavities alternately work in a circulating mode to provide clean compressed air for a downstream air path.

Chinese patent CN106015638a discloses a single-cylinder switching type intake and exhaust valve set, which realizes the switching of two cavities by the piston matching of a valve rod and a two-way sealing piston seal of a valve body inner cavity. However, the valve rod is abraded in the expansion process, so that the service life is short. And still need carry out the valves dismouting when the valve rod is changed, complex operation, inefficiency.
