Problems solved by technology

Due to the inadequacy of the valve structure in the prior art, the connection of the intake pipes at the bottom of the two tanks is relatively complicated, and at least four valves need to be installed on the pipelines to meet the intake and exhaust requirements of the two tanks working alternately. The cost is high, the installation and maintenance are inconvenient, the connection of components is complicated, and the performance is not stable

Abstract

The invention discloses a four-way valve used for an adsorption drier. An air inlet on one side wall of the valve body is communicated to an air inlet cavity, a waste gas outlet on another side wall opposite to the air inlet is communicated to a waste gas cavity, and a left air outlet and a right air outlet on another two side walls are respectively communicated to a left air outlet cavity and a right air outlet cavity; a valve clapboard of the air inlet cavity is provided with a left air inlet valve and a right air inlet valve, a valve clapboard of the left air outlet cavity is provided with a left exhaust valve, and a valve clapboard of the right air outlet cavity is provided with a right exhaust valve; the air inlet cavity is communicated with the left air outlet cavity through the left air inlet valve and a notch on the left side of the bottom edge of a first clapboard, and communicated with the right air outlet cavity through the right air inlet valve and a notch on the right side of the bottom edge of the first clapboard; the left air outlet cavity is communicated with the waste gas cavity through the left exhaust valve and a notch on the left side of the bottom edge of the clapboard of the waste gas cavity; and the right air outlet cavity is communicated with the waste gas cavity through the right exhaust valve and a notch on the right side of the bottom edge of the clapboard of the waste gas cavity. Only the left air outlet and the right air outlet of the four-way valve need to be respectively connected with two tanks; and the four-way valve reduces the production cost, is convenient for installation and maintenance, and improves the stability.

Description

technical field [0001] The invention relates to a component of an adsorption dryer, in particular to a four-way valve used for the adsorption dryer. Background technique [0002] The adsorption dryer combines the advantages of pressure swing adsorption and temperature swing adsorption. It adsorbs (works) at room temperature and high steam partial pressure, and resolves (regenerates) at higher temperature and low steam partial pressure. Moisture, in the regeneration process, is completely removed by the combination of thermal diffusion and low partial pressure of high-quality reproduction (dry air heating). The equipment is generally made of double tanks. Under the control of the program controller, the two tanks work alternately, one tank absorbs water, and the other tank decomposes and regenerates, working in a continuous cycle. Due to the inadequacy of the valve structure in the prior art, the connection of the intake pipes at the bottom of the two tanks is relatively com...
