Embodiment 1

[0043] Such as Figure 1 ~ Figure 2 As shown, the present invention discloses a flexible valve. In a specific embodiment of the present invention, it includes an upper valve body 11, a lower valve body 12, and a membrane sleeve 2 with a material delivery channel 21. The two ends of the membrane sleeve 2 are respectively Connected with the upper valve body 11 and the lower valve body 12, the upper valve body 11 or / and the lower valve body 12 can be axially rotatably connected, and when the upper valve body 11 or / and the lower valve body 12 rotate axially, the membrane sleeve 2 is driven to rotate Twist and form a sealing point 22 .

[0044] In a specific embodiment of the present invention, the matching ends of the upper valve body 11 and the lower valve body 12 can be connected by threaded connection.

[0045] In a specific embodiment of the present invention, one end of the membrane sleeve 2 is installed at the feed inlet of the upper valve body 11 through the quick disassem...

Embodiment 2

[0051] Embodiment 2, the difference with embodiment 1 is

[0052] Such as image 3 As shown, in a specific embodiment of the present invention, an automatic cleaning and disinfection device 5 is also included, and the automatic cleaning and disinfection device 5 includes a combined online cleaning upper assembly 51 installed on the upper valve body 11 and an upper assembly installed on the lower valve body 12. The upper combined online cleaning lower assembly 52; the combined online cleaning upper assembly 51 includes a spraying part 511 for spraying the inner wall of the membrane casing 2 and a cleaning and disinfecting machine 512 for delivering cleaning liquid to the spraying part 511 The combined online cleaning lower assembly 52 includes a drain pipe 521 for discharging the cleaning liquid inside the lower valve body 12 .

[0053] In a specific embodiment of the present invention, the combined online cleaning upper assembly 51 and the combined online cleaning lower assem...

Embodiment 3

[0055] Embodiment 3, the difference with embodiment 1 is

[0056] Such as Figure 4 As shown, in a specific embodiment of the present invention, the outer wall of the upper valve body 11 and / or the outer wall of the lower valve body 12 is provided with an inflation interface 6, and the inflation interface 6 is provided with a sealing detection device 61, and the sealing The detection device 61 includes an air pressure monitoring device 612 connected to the inflation interface 6 through an external pressure control valve 611 .

[0057] By adopting the above-mentioned technical scheme: inert gas (for example: nitrogen) can be filled into the gap formed between the membrane sleeve, the upper valve body and the lower valve body through the inflation interface. The purpose of this setting is to protect the transported materials The function is to prevent the secondary pollution caused by the contact between the material and the air. Secondly, through the air pressure monitoring de...

Abstract

The invention relates to a flexible valve. The flexible valve is characterized in that the flexible valve comprises an upper valve body, a lower valve body and a membrane sleeve, wherein the membranesleeve is provided with a material conveying channel; the two ends of the membrane sleeve are connected with the upper valve body and the lower valve body correspondingly; the upper valve body or/andthe lower valve body is/and connected in an axially-rotatable manner; and when the upper valve body or/and the lower valve body axially rotates, the membrane sleeve is driven to rotate and distort, and a sealing point is formed. The flexible valve has the beneficial effects that the external structure of a material is not damaged; dust-free isolation is achieved; and the flexible valve is great inblocking performance, wide in application scope, great in practicability and convenient to popularize.

Description

technical field [0001] The invention relates to the technical field of control equipment, in particular to a flexible valve. Background technique [0002] A valve refers to a control component used to transport materials, with functions such as cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief, etc. According to the functional classification of valves, there are mainly gate valves, butterfly valves, Globe valve, ball valve, pneumatic valve, etc. [0003] Although there are many types of valves, the existing valves are closed by hard mechanical contact, and the valves controlled by this method have the following common problems: [0004] Defects to the material: [0005] When the material to be conveyed is granular, massive, solid-solid mixture, or solid-liquid mixture, when the valve is closed, it will squeeze this type of material, resulting in damage to this type of material, and even directly...
