Problems solved by technology

However, the traditional structure of the dryer causes difficulties in some special environments: two butterfly valves or cylinders driven by compressed air are required as intake control valves, and two butterfly valves or two separate one-way valves driven by compressed air are required. As the air outlet control valve, two butterfly valves driven by compressed air are required as the discharge control valve. The structure is complex, the number of valves is large, the fault points are many, and the butterfly valve is easy to leak; the minimum working pressure is required to be above 0.4MPa (g). 0.4MPa (g) compressed air drying powerless
Due to the structure of the valve, the traditional compressed air dryer can only be installed vertically

Embodiment 1

[0030] Such as Figure 2-Figure 5 As shown, the intake valve assembly 2 includes an intake valve assembly body 201 with a lower air inlet 211, a first lower air outlet 212 and a second lower air outlet 213 and a 201 and is used to connect the lower air inlet 211 to the first lower air outlet 212 or the second lower air outlet 213 of the air intake valve assembly core ball 202 .

[0031] Such as Figure 2-Figure 5 As shown, the intake valve assembly 2 also includes an intake valve core tube 203 with an intake port 231 in the middle, a left outlet lower port 232 at the left end, and an intake valve core tube 203 with a right transition lower port 233 at the right end. There is an excessive lower port 241 on the left and an air intake valve core pad 204 with a lower air outlet port 242 on the right end, and an air intake hollow screw 205; The port 233 is installed in the intake valve body 201 in communication with the left excessive lower port 241, the left air outlet lower por...

Embodiment 2

[0066] From the description of Embodiment 1, we know that the heatless regenerative adsorption compressed air dryer uses the instantaneous pressure difference between the first accommodating chamber 101 and the second accommodating chamber 102 to drive the switching of the intake valve core ball 202 The first lower gas outlet 212 and the second lower gas outlet 213 are blocked, and then the first accommodating cavity 101 and the second accommodating cavity 102 are used to alternately dry the gas. The prerequisite for driving the intake valve core ball 202 to switch reliably is that the pressures of the first accommodating chamber 101 and the second accommodating chamber 102 are balanced before switching.

[0067] Because when the volume of the first storage chamber 101 and the second storage chamber 102 is large (that is, the processing capacity of the dryer is large), the regenerative throttling channel 103 with a specified size will be charged during the programmed charging t...

Abstract

The invention relates to an inlet valve assembly which comprises an air inlet valve body, an air inlet valve core ball, an air inlet valve core pipe, an air inlet valve core pad and an air inlet hollow screw, wherein the air inlet valve body is provided with a lower air inlet, a first lower air outlet and a second lower air outlet, and the air inlet valve core ball is arranged in the air inlet valve; an air inlet port is arranged in the middle of the air inlet valve core pipe, a left air outlet lower port is arranged at the left end of the air inlet valve core pipe, and a right transition lower port is arranged at the right end of the air inlet valve pipe; and a left transition lower port is arranged at the left end of the air inlet valve core pad, and a right air outlet lower port is arranged at the right end of the air inlet valve core pad. The air inlet valve core pipe and the air inlet valve core pad are communicated with each other and installed in the inlet valve body in communication mode, the left air outlet lower port is in sealing connection with the first lower air outlet, the right air outlet lower port is in sealing communication with the second lower air outlet, the air inlet port is in sealing communication with the lower air inlet, the air inlet valve core ball moves in the air inlet valve core pipe, an installation lower port is arranged on the air inlet valve body, and the air inlet hollow screw is arranged on the installation lower port and butts against the air inlet valve core pad. The inlet valve assembly is simple in structure, not easy to leak and safe.

Description

[0001] This application is a divisional application of the patent application No. 201110048212.3, titled heatless regenerative adsorption compressed air dryer. 【Technical field】 [0002] The invention relates to an intake valve assembly. 【Background technique】 [0003] The heatless regenerative adsorption compressed air dryer is a mature technology as a drying equipment for compressed air. However, the traditional structure of the dryer causes difficulties in some special environments: two butterfly valves or cylinders driven by compressed air are required as intake control valves, and two butterfly valves or two separate one-way valves driven by compressed air are required. As the air outlet control valve, two butterfly valves driven by compressed air are required as the discharge control valve. The structure is complex, the number of valves is large, the fault points are many, and the butterfly valve is easy to leak; the minimum working pressure is required to be above 0.4...
