Embodiment Construction

[0033] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific diagrams.

[0034] refer to Figure 1 to Figure 3 , Fluorine resin valve, including the valve body, the valve body includes the upper valve body 1, the piston valve body 2, the lower valve body 3, the valve base 4 and the metal bottom plate 5 from top to bottom. The upper valve body 1 and the piston valve body 2 are sealed and fixed by a sealing ring, and the piston valve body 2 and the lower valve body 3 are sealed and fixed by a sealing ring.

[0035] The lower valve body 3 is provided with an air inlet 31 and an air outlet 32, and the valve port between the air inlet 31 and the air outlet 32 ​​is opened and closed by the diaphragm 6. When the diaphragm 6 moves upward, the valve port opens and the air inlet 31 communicates with the air outlet 32, and when the...

Abstract

The invention belongs to the technical field of valves, and particularly relates to a fluororesin valve and a using method thereof. The fluororesin valve comprises a valve body, the valve body comprises a piston valve body and a lower valve body, an air inlet and an air outlet are formed in the lower valve body, a valve port between the air inlet and the air outlet is opened and closed through a diaphragm, when the diaphragm moves upwards, the valve port is opened, the air inlet and the air outlet are communicated, and when the diaphragm moves downwards, the valve port is closed, and the air inlet and the air outlet are separated; the lower valve body and the diaphragm are both made of perfluororesin materials. A piston is arranged in the piston valve body and can move up and down in the piston valve body, the bottom of the piston penetrates through the bottom face of the piston valve body and then is fixed to a diaphragm, and the piston drives the diaphragm to move up and down. The space above the piston is a piston upper cavity, the space below the piston is a piston lower cavity, and the piston upper cavity and the piston lower cavity are respectively connected with an adjusting opening. When the valve is applied to corrosive gas and liquid fluid, the valve body cannot be corroded and damaged.

Description

technical field [0001] The invention belongs to the technical field of valves, and in particular relates to a fluororesin valve and a using method thereof. Background technique [0002] Valves are easily eroded by fluids during use. For example, corrosive gas and liquid fluids are likely to cause damage to the valve body. Therefore, valve body components of specific materials are urgently needed to avoid valve damage. [0003] In addition, fluororesins have excellent properties such as high and low temperature resistance, dielectric properties, chemical stability, weather resistance, non-combustibility, non-stickiness and low coefficient of friction. It is an indispensable and important material for all sectors of the national economy, especially cutting-edge science and technology and defense industry. Contents of the invention [0004] The invention aims at the technical problem that the valve body is easily damaged by corrosive gas-liquid fluids, and aims to provide a ...
