Abstract
The utility model discloses a kind of novel dust removing valve, comprise valve seat, spool, pad pressing plate and dedusting pad, the contacting point of described valve seat and described spool is provided with the first seal ring and the second seal ring, described spool is connected with the top of described pad pressing plate, between described pad pressing plate and described valve seat, is provided with dedusting pad.The utility model provides a kind of novel dust removing valve, increase the dedusting pad with certain degree of hardness in sealing station bottom, in the time that valve opens and closes completely, dedusting pad contacts with valve seat, dirt on valve seat is removed simultaneously, ensure like this spatter property of sealing station, sealing effect has obtained enhancing, also extend the working life of dedusting pad, no matter dedusting pads placement is to open or close can not be exposed to all the time in medium, rugged environment in operating mode directly contact with sealing station never, sealing effect is good, effectively avoid the generation of major accident.
Description
Technical field
The utility model relates to a kind of new type of valve, relates in particular to a kind of novel dust removing valve.
Background technique
Valve is in fluid system, and the device that is used for controlling direction, pressure, the flow of fluid is the device that medium (liquid, gas, powder) in pipe arrangement and equipment is flowed or stop and controlling its flow.
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.For the valve of fluid control, from the simplest stop valve to very complicated robot control system(RCS) various valves used, its kind and specification are various, the inside nominal diameter of valve reaches greatly the industrial pipeline valve of 10m to latus rectum from atomic little Gauge Valves.The good valve of work 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-270 DEG C DEG C.
The control of valve can adopt the multiple kind of drive, as manual, electronic, surge, pneumatic, turbine, electromagnetic driven, electromagnetism surge, electricity surges, 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, or do not rely on transducing signal and simply open or close, valve relies on driving or automechanism to make open-shut device do lifting, slippage, swing or rotation motion, thereby the size that changes its Flow area is to realize its control function.
In gas-stove, can use valve, but coal dust in gas-stove, long can being attached on valve inwall with pipeline of oil stain time, if the dust accumulating on sealing surface is too many, while sealing so, seal ring can be worn and torn by dust, sealing effect is affected.
Model utility content
The purpose of this utility model is just to provide in order to address the above problem a kind of novel dust removing valve.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of novel dust removing valve, comprise valve seat, spool, pad pressing plate and dedusting pad, the contacting point of described valve seat and described spool is provided with the first seal ring and the second seal ring, described spool is connected with the top of described pad pressing plate, between described pad pressing plate and described valve seat, is provided with dedusting pad.
Particularly, described the first seal ring and described the second seal ring are rubber seal.
Further, described dedusting pad is rubber sheet gasket, and the surface of described rubber sheet gasket is coated with nanometer material.
The beneficial effects of the utility model are:
The utility model provides a kind of novel dust removing valve, increase the dedusting pad with certain degree of hardness in sealing station bottom, in the time that valve opens and closes completely, dedusting pad contacts with valve seat, dirt on valve seat is removed simultaneously, ensure like this spatter property of sealing station, sealing effect has obtained enhancing, also extend the working life of dedusting pad, no matter dedusting pads placement is to open or close can not be exposed to all the time in medium, rugged environment in operating mode directly contact with sealing station never, sealing effect is good, effectively avoid the generation of major accident.

Fig. 2 is the A part-structure schematic diagram in Fig. 1;
Fig. 3 is the B part-structure schematic diagram in Fig. 1;
Fig. 4 is the adjustment pre-structure schematic diagram of described spool.
In figure: 1-dedusting pad, 2-pad pressing plate, 3-the first seal ring, 4-spool, 5-the second seal ring, 6-valve seat.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figures 1 to 4, a kind of novel dust removing valve of the utility model, comprise valve seat 6, spool 4, pad pressing plate 2 and dedusting pad 1, the contacting point of valve seat 6 and spool 4 is provided with the first seal ring 3 and the second seal ring 5, spool 4 is connected with the top of pad pressing plate 2, between pad pressing plate 2 and valve seat 6, is provided with dedusting pad 1.The first seal ring 3 and the second seal ring 5 are rubber seal.Dedusting pad 1 is rubber sheet gasket, and the surface of rubber sheet gasket is coated with nanometer material.
The utility model increases the dedusting pad with certain degree of hardness in sealing station bottom, in the time that valve opens and closes completely, dedusting pad 1 contacts with valve seat, dirt on valve seat 6 is removed simultaneously, ensure like this spatter property of sealing station, sealing effect has obtained enhancing, also extend the working life of dedusting pad 1, no matter dedusting pad 1 position is to open or close can not be exposed to all the time in medium, rugged environment in operating mode directly contact with sealing station never, sealing effect is good, effectively avoids the generation of major accident.
Embodiment is above described preferred implementation of the present utility model; not scope of the present utility model is limited; design under spiritual prerequisite not departing from the utility model; various distortion and improvement that the common engineers and technicians in related domain make technical solutions of the utility model, all should fall in the definite protection domain of claims of the present utility model.
