Description
Technical Field
The utility model relates to a valve field of making, in particular to dustproof high leakproofness electric gate valve.
Background
The gate valve is a shutter plate, the movement direction of the shutter plate is vertical to the fluid direction, and the gate valve is sealed by the contact of a valve seat and the shutter plate to open and close the fluid in a flow passage.
Traditional gate valve only is provided with a single sealing filler below the axle sleeve, appears the filler after the long-time use of gate valve and reveals, and then influences holistic sealing performance.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a long service life's a dustproof high leakproofness electric gate valve.
The purpose of the utility model is realized like this: a dustproof high-sealing electric gate valve comprises an electric transmission device, a valve body, a valve rod, a valve plate and a fixing block; the electric transmission device is connected with the valve rod, an eccentric shaft hole is formed in the radial right side of the valve body, the valve rod penetrates through the eccentric shaft hole and is in rotary fit with the eccentric shaft hole, and the valve plate is connected with the valve rod through a fixing block; an upper graphite filler is arranged at the eccentric shaft hole on the upper side of the valve rod and the valve body; the upper graphite filler is arranged on the graphite pad and is compressed by the pressing sleeve; the graphite packing box is characterized in that a shaft sleeve is arranged below the upper graphite packing, a lower graphite packing is arranged below the shaft sleeve, and the lower graphite packing is arranged on the graphite pad.
Compared with the prior art, the utility model discloses an useful part lies in: the stuffing box is provided with two sections for secondary sealing through the pressing sleeve and the pressing cover, so that external dust is not easy to enter the stuffing box in the daily use process; meanwhile, the graphite pad below the stuffing box further ensures the sealing performance of the whole valve.
As the preferred scheme of the utility model, the valve rod drives and drives the valve plate through electric drive and rotates.
As a further preferred scheme of the utility model, be provided with the rhombus strengthening rib between fixed block and the valve plate.
As a further preferred scheme of the utility model, the graphite pad is formed for pure graphite plate punching press is integrative.
As a further preferred scheme of the utility model, press the cover top to carry out secondary seal through the gland and compress tightly.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is an enlarged schematic view of the a position of the present invention.
The device comprises an electric transmission device 1, a valve body 2, a valve rod 3, a valve plate 4, a fixing block 5, an eccentric shaft hole 6, graphite packing on the valve body 7, a graphite pad 8, a pressing sleeve 9, a shaft sleeve 10, graphite packing under the shaft sleeve 11, reinforcing ribs 12 and a pressing cover 13.
Detailed Description
As shown in fig. 1, the dustproof high-sealing electric gate valve comprises an electric transmission device 1, a valve body 2, a valve rod 3, a valve plate 4 and a fixed block 5; the electric transmission device 1 is connected with the valve rod 3, the valve body 2 is provided with an eccentric shaft hole 6 on the radial right side, the valve rod 3 penetrates through the eccentric shaft hole 6 and is in rotary fit, and the valve plate 4 is connected with the valve rod 3 through a fixing block 5; an upper graphite packing 7 is arranged at the positions of the valve rod 3 and the eccentric shaft hole 6 at the upper side of the valve body 2; the upper graphite filler 7 is arranged on the graphite pad 8 and is tightly pressed by the pressing sleeve 9; a shaft sleeve 10 is arranged below the upper graphite filler 7, a lower graphite filler 11 is arranged below the shaft sleeve 10, and the lower graphite filler 11 is arranged on the graphite pad 8.
The valve rod 3 is driven by the electric transmission device 1 and drives the valve plate 4 to rotate.
A diamond reinforcing rib 12 is arranged between the fixed block 5 and the valve plate 4.
The graphite pad 8 is formed by punching a pure graphite plate into a whole.
And the upper part of the pressing sleeve 9 is compressed for the second time in a sealing way through a pressing cover 13.
The working principle of the utility model is explained as follows: when the valve is exposed to a dust environment, dust can sequentially pass through the pressing cover 13, the pressing sleeve 9 and the graphite pad 8 at the matching position of the valve body 2 and the valve rod 3, the possibility that the dust enters the interior is greatly reduced through layer-by-layer separation, and meanwhile, compared with a single packing box, the whole sealing performance and diversity of the valve are greatly enhanced by the upper graphite packing 7 and the lower graphite packing 11 which are designed in a two-section mode.
The present invention is not limited to the above embodiments, and based on the technical solutions disclosed in the present invention, those skilled in the art can make some replacements and transformations for some technical features without creative labor according to the disclosed technical contents, and these replacements and transformations are all within the protection scope of the present invention.
