Abstract
The utility model relates to a part of a valve, in particular to a rotary shaft of an air door rotary valve. The rotary shaft of the air door rotary valve mainly resolves the technical problems in the prior art that a valve is complex in structure, high in manufacturing cost, inconvenient to rotate, short in service life and the like. The rotary shaft of the air door rotary valve comprises a rotary shaft body (1) and is characterized in that a first steel plate (2) and a second steel plate (3) are symmetrically fixed to the rotary shaft body (1), the first steel plate and the second steel plate are not on the same plane and parallel with each other, bolt holes (4) in rows are formed in the first steel plate and the second steel plate respectively.
Description
Technical field
The utility model relates to a kind of valve components, especially relates to the rotating shaft of a kind of air door rotary valve.
Background technique
Valve is controlling component in pipeline fluid transporting system, and it is for changing path section and media flow direction, has the functions such as water conservancy diversion, cut-off, throttling, non-return, shunting or overflow release.The valve of controlling for fluid, from the simplest stop valve to very complicated robot control system(RCS) various valves used, its kind and specification are various.Valve can be used for controlling all kinds such as water, steam, oil product, gas, mud, various Korrosionsmedium, liquid metal and radioactive fluid and fluidly flows, the working pressure of valve can be from 0.0013MPa to 1000MPa ultrahigh pressure, operating temperature is from the high temperature of the ultralow temperature to 1430 of-269 ℃ ℃.The control of valve can adopt the multiple kind of drive, as manual, electronic, surge, pneumatic, worm gear, electromagnetic driven, electricity surge, air-or liquid-operated, spur wheel, umbrella gear driving etc.; Can be under the effect of pressure, temperature or other form transducing signal, by predetermined requirement action, valve relies on driving or automechanism to make it do lifting, slippage, swing or rotation motion, thus the size that changes its Flow area is to realize its control function.But existing valve hinges structure is comparatively complicated, and manufacture cost is higher, rotate comparatively inconvenience, working life is shorter.
Model utility content
The utility model is to provide the rotating shaft of a kind of air door rotary valve, and it is mainly that to solve the existing valve hinges structure of prior art comparatively complicated, and manufacture cost is higher, rotates comparatively inconvenience, working life shorter grade technical problem.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Air door rotary valve of the present utility model rotating shaft, comprise rotating shaft body, on described rotating shaft body, be symmetrically fixed with the first steel plate, the second steel plate, the first steel plate, the second steel plate not at grade and setting parallel to each other, have the screw setting in a row on the first steel plate, the second steel plate.
As preferably, described rotating shaft body wherein has taper pin-hole in one end.
Therefore, valve hinges structure of the present utility model is comparatively simple, reasonable, and manufacture cost is lower, and more for convenience, it is comparatively easy to rotate in processing, and working life is higher.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the air door rotary valve rotating shaft that this is routine, as Fig. 1, comprise rotating shaft body 1, on rotating shaft body, be symmetrically fixed with the first steel plate 2, the second steel plate 3, the first steel plate, the second steel plate not at grade and setting parallel to each other, have the screw 4 setting in a row on the first steel plate, the second steel plate.Rotating shaft body wherein one end has taper pin-hole 5.
The foregoing is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification are all encompassed among the scope of the claims of the present utility model.
Claims (2)
1. air door rotary valve rotating shaft, comprise rotating shaft body (1), it is characterized in that being symmetrically fixed with the first steel plate (2), the second steel plate (3) on described rotating shaft body (1), the first steel plate, the second steel plate not at grade and setting parallel to each other, have the screw (4) setting in a row on the first steel plate, the second steel plate.
