Example Embodiment

[0012] The present invention will be further described below in conjunction with the embodiments shown in the drawings.

[0013] Such as figure 1 As shown, the one-way valve includes a valve body 1, a one-way bendable valve plate 2 installed in the valve body 1, and the valve plate 2 includes an air inlet orifice plate 3 tightly connected to the inner side wall of the valve body 1. , The rubber ring 4, which can be bent in one direction, is connected to the air inlet orifice plate 3. When no gas enters the valve body 1, the rubber ring 4 is closely attached to the valve body 1. 1 When the air inlet enters, a gap is formed between the bending of the rubber ring 4 and the valve body 1. The rubber ring 4 and the air inlet hole plate 3 are fixedly connected by a bolt assembly 5. The valve body 1 is composed of two symmetrical shells 6, and the joint surface of the two shells 6 is perpendicular to the axis of the valve body 1. The inner cavity of the valve body 1 is composed of a m...

Abstract

The invention discloses a one-way valve. The one-way valve comprises a valve body, and a valve plate mounted in the valve body and capable of being bent in one direction; the valve plate comprises anintake hole plate tightly connected with the inner side wall of the valve body, and a rubber ring connected to the intake hole plate and capable of being bent in one direction; when no gas enters thevalve body, the rubber ring is tightly bonded with the valve body; and when the gas enters from an intake port of the valve body, the rubber ring is bent to form a gap with the valve body. As the rubber ring and the intake hole plate are tightly connected, when the closing is needed, the rebound speed of the rubber ring can be accelerated through the intake hole plate to guarantee no dust to return to the intake port to damage various valves on an intake pipe.

Description

Technical field [0001] The invention relates to pneumatic ash conveying equipment, in particular to a one-way valve. Background technique [0002] The existing one-way valve of pneumatic ash conveying system has many problems, such as: ash and its mixture will be generated in the air outlet part, and the existing valve plate cannot rebound and seal in time after the opening is deformed, causing some dust to return to the inlet. Air port, dust will damage various valves on the intake pipe. Summary of the invention [0003] The purpose of the present invention is to provide a one-way valve whose air inlet orifice can increase the rebound speed of the rubber ring when it needs to be closed, and ensure that dust will not return to the air inlet and damage various valves on the air inlet pipe. [0004] In order to achieve the above objective, the technical solution adopted by the present invention is: a one-way valve, which includes a valve body, a one-way bendable valve plate installed...
