Embodiment Construction

[0021] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.

[0022] Such as Figure 1-3 As shown, the self-tightening and sealing piston gas holder of this embodiment includes a gas holder cylinder body 1 and a piston 2, and at least one set of self-tightening sealing components 3 arranged between the gas holder cylinder body 1 and the piston 2. The tight sealing assembly 3 moves up and down the traction device 4 that acts as a guide, and the fixing device 5 that fixes the sealing assembly on the piston. The self-tight sealing assembly 3 includes a sealing belt 301, a sealing belt pressing plate 302, "U" or "C" Type film 303, baffle plate 304, the opening of the "U" or "C" type film 303 faces downward, and the sealing belt pres...

Abstract

The invention discloses a self-tightening seal type piston gas chamber and belongs to the technical field of gas holders. The self-tightening seal type piston gas chamber comprises a gas chamber barrel body and a piston and is characterized by further comprising at least one group of self-tightening sealing modules arranged between the gas chamber barrel body and the piston, a traction device playing a guide role on vertical movement of the self-tightening sealing modules and a fixing device for fixing the sealing modules to the piston, wherein each self-tightening sealing module comprises a sealing band, a sealing band press plate, a U or C shaped film, and a baffle. The opening of the U or C shaped film is downward, and the sealing band press plate and the baffle are respectively arranged on two sides of the U or C shaped film. The self-tightening seal type piston gas chamber directly uses gas pressure of the gas chamber as pressing force to achieve seal through the self-tightening sealing modules. Due to the fact that the gas pressure in the gas chamber is constant, the pressing force is constant, the sealing effect and safety of the self-tightening seal type piston gas chamber are remarkably improved, sealing power provided by the outside is not needed, and the self-tightening seal type piston gas chamber has the advantages of being simpler in structure, low in energy waste and low in using cost.

Description

technical field [0001] The invention belongs to the technical field of gas storage tanks, and relates to a self-tightening and sealing piston gas tank. Background technique [0002] In the labyrinth space composed of traditional multi-channel sealing rubber, the gas seal is formed by adding force to the multi-channel sealing rubber to form a gap resistance. The labyrinth seal is formed through the gap resistance, and the piston sealing ring is formed by the multi-channel sealing rubber. The formation of these rings is similar to The principle of the labyrinth seal, the gas is blocked once after passing through the annular seam of one ring, and the pressure is reduced once, and the gas is sealed after passing through the annular seams of multiple rings. It is imperative to open up a new path. [0003] The traditional Kolon oil-sealed gas holder uses the principle of a lever weight to seal, but there is a problem of high gas leakage rate. The main reason is that due to the co...
