The low-flow-resistance pipeline valve device structure solves the problem that flow resistance is large when fluid flows through a pipeline in the prior art. According to the technical scheme, the low-flow resistance pipeline valve device structure comprises a spittoon-shaped valve case and a fusiform valve core body, wherein the valve core body is connected on a transmission gear rack and a supporting rod, and the valve core body is supported inside the valve case through an entrance support ring and an exit support ring of the valve. A transmission gear is connected on a transmission shaft through keys in a matching mode and is fixed through a check ring, the transmission shaft is fixedly arranged on a shaft base through a bearing, and the transmission gear is meshed with the transmission gear rack. One end of the transmission shaft penetrates through the valve case and is connected with a manual operated handle. An entrance end and an exit end of the valve case are connected with gas pipelines in a sealing mode. A locking gear is connected on a locking shaft through a bearing 619/8-2Z, the locking shaft is connected on a shaft base through a bearing 619/3-2Z, and the locking gear is meshed with the transmission gear rack. The low-flow-resistance pipeline valve device structure is suitable for the field of environmental control rescue.
Description
Technical field
The utility model relates to aviation ring control lifesaving field, relates in particular to a kind of low flow resistance pipeline valve arrangement structure.
Background technique
Line fluid can be converted into mechanical load function on valve by the flow resistance of valve, the mechanical load that high-velocity fluid acts on the valve is bigger, portability to working life, sealing and the operation of valve has a negative impact, can produce high-power level noise simultaneously, the physical and mental health that directly endangers the operator.At present, the corrective measure of taking mainly is with valve body wall or central partition plate thickening, optimization system topology layout and valve connect the rigidity of dish, and the design improvement of carrying out from the valve structure angle is less relatively, not the big problem of flow resistance when solving line fluid by valve in essence.
The model utility content
The purpose of this utility model is: a kind of low flow resistance pipeline valve arrangement structure is provided, and the flow resistance when reducing line fluid by valve reduces line fluid and acts on mechanical load on the valve, the noise when reducing fluid by valve; Improve the opening and closing reliability of valve and be convenient to operation.
The technical solution of the utility model is: a kind of low flow resistance pipeline valve arrangement structure, it is characterized in that, and comprising:
Spittoon shape valve shell and fusiformis valve core body, the valve core body is connected on driving rack and the strut, is supported in the valve shell by valve entrance bracing ring and outlet bracing ring; Driving gear is connected on transmission shaft by key, is fixed by back-up ring;
On shaft stool, driving gear and driving rack mesh transmission shaft by bearing fixing, and transmission shaft one end passes the valve shell and is connected with the manually-operable handle; The entry end of valve shell and outlet end and gas pipeline are tightly connected;
Stopping gear is connected on the braking roll by bearing 619/8-2Z, and braking roll is connected on the shaft stool by bearing 619/3-2Z, stopping gear and driving rack engagement.
The beneficial effects of the utility model are: compared with prior art, the utility model improves by the valve overall construction design, flow resistance is very little when making line fluid pass through valve, and valve body does not need to thicken design, reduces valve weight when improving the valve performance.The opening and closing of valve cooperate realization by rack and pinion, the reliability height, and can be designed to manually-operable or connect AC motor carry out electric operating, make things convenient for engineering to use.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
Task of the present utility model and purpose are the flow resistance when the design improvement of valve structure is reduced line fluid by valve, reduce line fluid and act on mechanical load on the valve, use normal or thinner material can carry out the valve manufacturing; Noise when reducing fluid by valve to a certain extent by the valve structure design simultaneously; The opening and closing reliability of last valve is high and be convenient to operation.
Shown in Fig. 1,2,3a, 3b, the utility model is made up of spittoon shape valve shell 1 and fusiformis valve core body 2, and valve core body 2 is connected on driving rack 9 and the strut 13, is supported in the valve shell by valve entrance bracing ring 14 and outlet bracing ring 6; Driving gear 11 is connected on transmission shaft 4 by key, and is fixing by back-up ring 10.
Transmission shaft 4 on shaft stool, is realized driving gear 11 and driving rack 9 engagements by bearing fixing, and transmission shaft 4 one ends pass the valve shell and are connected with manually-operable handle 3, realizes the opening and closing of valve by operating manual operating handle 3.The entry end of valve shell 1 and outlet end and gas pipeline are tightly connected, guarantee that the inner minimum stream flux of valve is identical with valve entrance discharge value, make line fluid pass through gently with streamlined in valve inside, reduce flow resistance greatly, valve body no longer needs to thicken design.
When preventing that gas load is big, it is poor that driving rack and driving gear go out point gearing, design has stopping gear 8 to be connected on the braking roll 5 by bearing (619/8-2Z) 7, braking roll 5 is connected the engagement that realizes stopping gear 8 and driving rack 9 on the shaft stool 12 by bearing (619/3-2Z) 15, realizes carrying out horizontal stop in the valve opening and closing process.
Valve core body 2 is welded on the structure circle 18 by core body outer wall 16, core body mesospore 19 and core body inwall 21 and forms, and core body mesospore 19 and core body inwall 21 carry out the micropunch design, and the aperture is Φ 0.5mm, and punching rate is 2.7%; Fill super glass wool 17,20 in the middle of the core body wall, density is 30kg/m
3, can reduce the noise that fluid produces by valve.
