Wafer type shuttle valve

Abstract

The invention discloses a wafer type shuttle valve. The wafer type shuttle valve comprises a shuttle valve body, a shuttle valve baffle, a shuttle valve sleeve, a shuttle valve element and a flow adjusting device, wherein a first air inlet and a second air inlet are formed in the two sides of the shuttle valve body respectively, baffle inner and outer channel is arranged between the first air inlet and the second air inlet and the flow adjusting device, and the first air inlet is connected with the second air inlet through the baffle inner and outer channel; the flow adjusting device is arranged below the shuttle valve body, the first air inlet is connected with the shuttle valve element through an openable channel, and the second air inlet is connected with the shuttle valve element through the openable channel; and the shuttle valve baffle and the shuttle valve sleeve are both arranged between the shuttle valve body and the shuttle valve element, an air outlet is formed in the upperpart of the shuttle valve body, and wafer type screw holes are formed in the two sides of the shuttle valve body. The wafer type shuttle valve has the advantages that the structure is compact, the size in small, the appearance is attractive, flange connection is adopted, twisted threads or welding are not needed, leakage points do not exist basically, the assembly is very convenient, and the maintenance of the product and the replacement of the valve are very convenient and rapid.

Description

technical field [0001] The invention relates to the field of compressed air purification, in particular to a wafer type shuttle valve. Background technique [0002] The structure of the regeneration part of the upper outlet of the heatless regenerative adsorption dryer in the prior art is currently relatively loose. In the prior art, two large flow check valves D and F (check valve, check valve) are usually used. Add a small flow regulating valve E in parallel or a shuttle valve plus a small flow regulating valve in parallel. The valves are connected by pipes. The working principle is that when barrel A is adsorbed and barrel B is regenerated, the corresponding inlet valve J is opened, K is closed, regeneration vent valve H is closed, and I is opened. After compression, the saturated humid air passes through valve J, is dried by the adsorbent in adsorption barrel A, and then exits from C through outlet check valve D (check valve, check valve) or shuttle valve, and check val...

AI Technical Summary

Problems solved by technology

The regeneration part of the upper outlet of the existing heatless regenerative adsorption dryer is a combination of multiple valves, which are two large flow one-way valves (check valve, check valve) or a shuttle valve and a small flow regulating valve connected in parallel. , and most of them are welded or screwed connection structures, which mainly have the following defects: loose structure, bulky, unsightly appearance; heavy assembly workload, difficult assembly, and screw connections are prone to leaks, welding slag inside the welded connection Difficult to clean, not suitable for mass production; valve maintenance, spool replacement is troublesome and time-consuming
