Embodiment Construction

[0032] The present invention will be further described below in conjunction with accompanying drawing description and specific embodiment:

[0033] Such as figure 1 or image 3 As shown in the figure, a miniature discharge valve includes a housing 1, a valve core 2 and an adapter 3; The other end fits with the adapter 3.

[0034] The housing 1 and the valve core 2 are sealed by a sealing ring 4 , and the valve core 2 is sealed by a plug 5 .

[0035] Such as figure 2 As shown, the adapter 3 is a cylindrical structure, and the adapter 3 is provided with a first flange 301, a second flange 302 and a third flange 303 in sequence, and the first flange 301, the second flange 302 and the third flange The radius ratio of the flange 303 is 3:4:5, and both ends of the adapter 3 are chamfered.

[0036] The housing 1 has a cylindrical structure, and a stepped through hole for matching the valve core 2 is provided in the housing 1, and both the housing 1 and the plug 5 are made of ti...

Abstract

The invention discloses a microminiature feeding and discharging valve. The microminiature feeding and discharging valve comprises a shell, a valve element and an adapter. The valve element penetrates the shell, one end of the valve element ejects the inner wall of the shell, the other end of the valve element is attached to the adapter, the part between the shell and the valve element is sealed through sealing rings, and the valve element is airtight through a stopper. According to the microminiature feeding and discharging valve, by means of cooperation of the shell and the valve element, the size of the feeding and discharging valve is reduced, and the problem that a traditional feeding and discharging valve is large in size is solved; by means of cooperation of the valve element and the adapter, the structure of the feeding and discharging valve is optimized, and the defect that the traditional feeding and discharging valve is complex in structure is overcome; and by means of arrangement of the sealing rings and the stopper, the sealing effect of the feeding and discharging valve is enhanced, and the problem that the traditional feeding and discharging valve is low in sealing performance is solved.

Description

technical field [0001] The invention relates to a miniature adding and discharging valve, which is especially suitable for a liquefied gas propulsion system of a tiny satellite, and belongs to the technical field of mechanical valve groups. Background technique [0002] In the prior art, filling and discharging valves are widely used in pressurization equipment and vacuum equipment in daily life, such as refrigerant filling ports of air conditioners and the like. In the field of aerospace, the discharge valve is mainly used for the filling and discharge of rocket or satellite propellant and pressurized gas. At present, the traditional filling and discharging valves used on spacecraft mostly adopt a "T"-shaped structure. The valve opening is separated from the liquid filling port. Facilitate module integration. In recent years, micro-satellites have developed rapidly, and there is an urgent demand for miniaturized valves that can be integrated with satellite structures. Acc...
