Abstract
The utility model relates to a valve, in particular to a sealed type spiral gate, and mainly solves the technical problem that a valve structure is complex, the manufacturing cost is higher, the valve is inconvenient to open and close, the service life is shorter, and the like in the prior art. The sealed type spiral gate comprises a framework (1) and is characterized in that the framework (1) is cuboid-shaped; a press strip (2) is connected to the framework; a gate plate (3) is arranged in the framework; a nut (4) is connected to the gate plate; a screw rod (5) is connected to the nut; a hand wheel (7) is fixed at the outer end of the screw rod; a plastic pipe (6) is arranged on the periphery of a valve rod; and a galvanized iron wire (10) is arranged at the nut.
Description
Technical field
The utility model relates to a kind of valve, especially relates to a kind of sealed type spiral gate.
Background technique
Valve is controlling component in the 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 and drives or automechanism makes it do lifting, slippage, swing or rotation motion, thus the size that changes its Flow area is controlled function to realize it.But existing valve mechanism is comparatively complicated, and manufacture cost is higher, open and close comparatively inconvenience, working life is shorter.
The model utility content
The utility model is to provide a kind of sealed type spiral gate, and it is mainly that to solve the existing valve mechanism 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:
Sealed type spiral gate of the present utility model, comprise framework, described framework is rectangular build, framework is connected with press strip, is provided with flashboard in framework, and flashboard is connected on nut, nut is connected with screw mandrel, the outer end of screw mandrel is fixed with handwheel, the outer plastic tube that is arranged with of valve rod, and the nut place is provided with galvanized wire.
As preferably, described screw mandrel cross-under is in bearing, and bearing is provided with the oilhole lid.
Therefore, valve mechanism 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.
The 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 sealed type spiral gate that this is routine, as shown in Figure 1, Figure 2, comprise framework 1, framework is rectangular build, and framework is connected with press strip 2, be provided with flashboard 3 in framework, flashboard is connected on nut 4, and nut is connected with screw mandrel 5, and the outer end of screw mandrel is fixed with handwheel 7, the outer plastic tube 6 that is arranged with of valve rod, the nut place is provided with galvanized wire 10.The screw mandrel cross-under is in bearing 8, and bearing is provided with oilhole lid 9.
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 all are encompassed among the scope of the claims of the present utility model.
