In order to achieve the above purpose, the technical scheme of the utility model is as follows:
the utility model provides a filter for hydrogen gas filling machine, includes filter housing, gland and lower gland are installed respectively to filter housing's both ends, filter housing's inside is provided with the cushion chamber, the internally mounted of cushion chamber has the filter core.
In the above scheme, the middle part of the upper gland is provided with the gas filling port, the middle part of the lower gland is provided with the gas exhaust port, and the gas filling port and the gas exhaust port are arranged oppositely.
In the above scheme, the bottom of the upper gland is provided with a sealing plug of an integrated structure, and the middle part of the sealing plug is provided with an air delivery hole.
In the scheme, the air delivery hole is arranged between the filter element and the air filling port.
In the above scheme, the hard sealing cushion block is installed at one end of the filter element, and the hard sealing cushion block is sealed between the sealing plug and the filter element.
In the scheme, the tail end of the filter element is set to be in a conical structure, and a gap is reserved between the outer diameter of the filter element and the caliber of the inner cavity of the buffer cavity.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a bottom of going up the gland is provided with the sealing plug of a body structure, conveniently will go up the gland seal in filter housing's one end through the sealing plug, be provided with the cushion chamber in filter housing's inside, there is the filter core at the internally mounted of cushion chamber, and install hard seal cushion between the one end of filter core and the sealing plug, a section of thick bamboo hard seal cushion makes the sealing performance of filter core and sealing plug improve greatly, can improve the filter effect to gas, avoid waste gas to spill over, improve filtration efficiency.
