Abstract
The utility model relates to a part of a valve, in particular to a valve element of an air door rotary valve. The valve element 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 open and close, short in service life and the like. The valve element of the air door rotary valve comprises a rotary shaft (1) and is characterized in that the rotary shaft (1) is symmetrically connected with a first steel plate (2) and a second steel plate (3), a pressing plate (5) is fixed to the outer end of the first steel plate and the outer end of the second steel plate through studs, a valve plate (6) is pressed at the inner side of the pressing plate, and a spring (7) is arranged between the valve plate and the pressing plate.
Description
Technical field
The utility model relates to a kind of valve components, especially relates to a kind of air door rotary valve spool.
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 spool of valve structure is comparatively complicated, and manufacture cost is higher, open and close comparatively inconvenience, working life is shorter.
Model utility content
The utility model is to provide a kind of air door rotary valve spool, and it is mainly that to solve the existing valve spool of valve structure of prior art comparatively complicated, and manufacture cost is higher, opens and closes 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 spool of the present utility model, comprise rotating shaft, described rotating shaft is symmetrically connected with the first steel plate, the second steel plate, and the outer end of the first steel plate, the second steel plate is fixed with pressing plate by stud bolt, pressing plate inner side is pressed with valve plate, between valve plate and pressing plate, is provided with spring.
As preferably, described the first steel plate or the stud bolt on the second steel plate are more than 2.
Therefore, valve spool of valve structure of the present utility model is comparatively simple, reasonable, and manufacture cost is lower, and more for convenience, it is comparatively easy to open and close in processing, and working life is higher.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is A-A cross-sectional view of Fig. 1.
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 spool that this is routine, as shown in Figure 1, Figure 2, comprises rotating shaft 1, rotating shaft is symmetrically connected with the first steel plate 2, the second steel plate 3, the outer end of the first steel plate, the second steel plate is fixed with pressing plate 5 by stud bolt 4, and pressing plate inner side is pressed with valve plate 6, is provided with spring 7 between valve plate and pressing plate.Stud bolt 4 on the first steel plate or the second steel plate 3 is more than 2.
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. an air door rotary valve spool, comprise rotating shaft (1), it is characterized in that described rotating shaft (1) is symmetrically connected with the first steel plate (2), the second steel plate (3), the outer end of the first steel plate, the second steel plate is fixed with pressing plate (5) by stud bolt (4), pressing plate inner side is pressed with valve plate (6), is provided with spring (7) between valve plate and pressing plate.
