Description
Technical field
The utility model relates to modulating valve technical field, especially a kind of modulating valve that is applicable to water, oil, gas and some corrosive liquids.
Background technique
Modulating valve has another name called control valve, in industrial automation process control field, by accepting the control signal of regulation unit output, removes to change the final control unit of the process parameters such as rate-of flow, pressure, temperature, liquid level by power operation.As the one of modulating valve, traditional butterfly valve structure complexity, complex operation, and poor sealing performance, working life is short, easily causes to leak to cause occurring security incident.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of simple in structure, the butterfly valve of good seal performance.
The utility model solves the technological scheme that its technical problem adopts: a kind of wafer type Pneumatic butterfly valve, there is valve body, be arranged on the valve rod in valve body, on described valve rod, interlock is provided with valve plate, described valve body is provided with the seal ring with valve plate fitted seal, between described valve body and valve rod, form Seal cage, in Seal cage, be provided with filler.Filler material is teflon.
Further, easy and simple to handle for wafer type Pneumatic butterfly valve, described valve rod top is provided with the pneumatic actuating device that actuate valve stem is rotated.
Further, in order to make wafer type Pneumatic butterfly valve have better sealability, described seal ring is the fine oil resistant rubber seal ring of fourth.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, are provided with pneumatic actuating device, make butterfly valve easy to operate, time saving and energy saving, are provided with seal ring and filler in valve body, have more improved the sealability of butterfly valve.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Wherein: 1. valve body, 2. valve rod, 3. valve plate, 4. seal ring, 5. filler, 6. pneumatic actuating device.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
Wafer type Pneumatic butterfly valve as shown in Figure 1, have valve body 1, be arranged on the valve rod 2 in valve body 1, on valve rod 2, interlock is provided with valve plate 3, and valve body 1 is provided with the seal ring 4 with valve plate 3 fitted seal, between valve body 1 and valve rod 2, form Seal cage, in Seal cage, be provided with filler 5.
Valve rod 2 tops are provided with the pneumatic actuating device 6 that actuate valve stem 2 is rotated.
Seal ring 4 is the fine oil resistant rubber seal ring of fourth.
When this wafer type Pneumatic butterfly valve work, open pneumatic actuating device 6 actuate valve stem 2, then drive valve plate 3 to turn to desired location; In the time that wafer type Pneumatic butterfly valve is closed, valve plate 3 and valve body 1 closure, under the effect of seal ring 4, form enclosed cavity.
Taking above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this model utility technological thought, carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to claim scope.
