Description
(1) technical field
The present invention relates to a kind of control valve, especially relate to the pneumatic integral type control valve of a kind of reducing furnace charging.
(2) background technique
At present, in the polycrystalline silicon reducing furnace feeding process,, adopt control valve to come charging is controlled usually for fear of in-plant operation; In actual applications, forbid adopting solenoid valve and mortor operated valve to be controlled,, belong to inflammable and explosive medium in the middle of the reducing furnace raw material because the polysilicon working environment can not have charged use product as control valve, there is consumer will produce static if any leakage situation, therefore can produces explosion risk; Thereby some manufacturer begins to adopt pneumatic control valve to replace solenoid valve and mortor operated valve now, but since its be not be for the reducing furnace charging custom-designed, in use find because conventional pneumatic control valve body adopts tubular-shaped structures, valve seat vertically is installed on valve body it is carried out opening and closing operations, thereby make valve pocket flow area maximum only be the sectional area of this tubular-shaped structures, thereby when needing to obtain bigger valve pocket flow area, need to use larger sized valve body, thereby cause The whole control valve body type bigger, and bigger build to cause control valve to be installed on reducing furnace limited; And the conventional pneumatic control valve modes that adopt air inlet in the annular space of side cause charge flow rate less more, are not easy valve body is carried out open and close controlling.
(3) summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of volume small and exquisite, be convenient to install and control the pneumatic integral type control valve of reducing furnace charging easily.
The object of the present invention is achieved like this: the pneumatic integral type control valve of a kind of reducing furnace charging, include valve body, valve rod and cylinder block, described valve body is one " Y " shape structure, described cylinder block is installed in the top open part of valve body, described valve rod places in valve body and the cylinder block, be set with valve seat on the described valve rod successively, valve gap, cylinder head and piston, described valve seat is fixed in stem bottom, described piston is fixed in the valve rod top, described valve gap is placed in the open top end of valve body, there is a little spring to be set on the valve rod, and this little spring is between valve gap and cylinder head, have a big spring to be set on the valve rod, and this big spring is between cylinder head and piston, the casing wall outside top position of described cylinder block is equipped with a gas source connector.
The pneumatic integral type control valve of reducing furnace charging of the present invention, described cylinder block crown center has a through hole, and the top of described valve rod is connected with an indicating arm, and this indicating arm passes above-mentioned through hole, and the described cover of looking is installed on the above-mentioned through hole.
The pneumatic integral type control valve of reducing furnace charging of the present invention, described look to be provided with between cover and the cylinder block look cover O shape circle and seal.
The pneumatic integral type control valve of reducing furnace charging of the present invention, being provided with sealing gasket between described valve gap and the valve body seals, be set with gland between described valve seat and the valve gap, this gland is fixed on the valve rod by straight pin, be filled with filler between described valve gap and the valve rod, be pressed with a little plain cushion on the described filler, this little plain cushion is set on the valve rod simultaneously, being provided with cylinder body O shape circle between described cylinder head and the cylinder block seals, described big spring and piston are provided with a big pad, being provided with valve rod O shape circle between described piston and the valve rod seals, be provided with piston O shape circle between described piston and the cylinder block and seal, the neutral position, the casing wall outside of described cylinder block is equipped with a silencing apparatus.
Working principle of the present invention is:
Under the effect of big spring power, valve is in normally open;
When need cylinder top feeding 0.3-0.8Mpa gas, the pressure of gas acts on piston, overcomes spring force valve rod is jacked down, and valve seat closely is pressed on the valve body sealing surface, cuts off medium;
Discharge gas when cylinder top, big spring gets on piston head, drives on the valve rod and moves, and valve seat breaks away from valve body sealing surface, valve open.
The invention has the beneficial effects as follows:
1) valve body Y shape design, with respect to original tubular-shaped structures, the oblique setting of valve pocket flow area, under the situation of equal volume size, Y shape structure has bigger flow area, thereby, under the situation of the equal flow of needs, Y shape structure has littler volume, thereby also more convenient user installs;
2) pneumatic control is fit to telecontrol, guarantees operator's personal safety; And than original mode to side annular space air inlet, feed gas at head room, comparatively speaking, throughput is bigger, easier valve body is controlled;
3) the product design of Sealing Structure is the sealing of tapering form, good seal performance, zero leakage.
