Abstract
The utility model relates to the technical field of butterfly valves, in particular to an adjustable shaft hole sealing filler structure, which comprises a pressing plate, a pressing sleeve, a sealing filler and a pressing bolt; the sealing packing is arranged in a shaft hole between the valve shaft and the valve body, the pressing sleeve is sleeved on the valve shaft and presses the upper part of the sealing packing, the pressing plate is arranged on the pressing sleeve, and the pressing bolt penetrates through the outer side of the pressing plate and is in threaded connection with the top of the valve body. This device compresses tightly the sealing filler through pressing the cover, drives the clamp plate through housing bolt and compresses tightly the pressure cover downwards to can adjust the degree of compaction of sealing filler, after the sealing filler wearing and tearing, adjust sealing filler through adjusting housing bolt, through the spring, can make sealing filler all have a decurrent power all the time, thereby improve sealing filler's sealing performance.
Description
Technical Field
The utility model relates to a butterfly valve technical field especially relates to an adjustable shaft hole sealing packing structure.
Background
The shaft hole of the valve body is an important part for sealing, if the sealing is not good, serious liquid leakage can occur, the shaft hole of the valve in the prior art mainly adopts a structure of a packing box, the packing structure can be abraded under the long-time use condition, and the larger the abrasion is, the more obvious the leakage is.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a main objective is exactly to above-mentioned problem, provides an adjustable shaft hole sealing filler structure, prevents to leak outward.
The utility model discloses a realize above-mentioned purpose, adopt following technical scheme: the utility model provides an adjustable shaft hole sealing filler structure which characterized in that: comprises a pressing plate, a pressing sleeve, a sealing filler and a pressing bolt; the sealing packing is arranged in a shaft hole between the valve shaft and the valve body, the pressing sleeve is sleeved on the valve shaft and presses the upper part of the sealing packing, the pressing plate is arranged on the pressing sleeve, and the pressing bolt penetrates through the outer side of the pressing plate and is in threaded connection with the top of the valve body.
Preferably, a nut is arranged at the top of the pressing bolt, a spring is arranged between the nut and the pressing plate, and the spring is sleeved on the pressing bolt.
Preferably, the contact surface between the pressure plate and the pressure sleeve is an inclined surface.
The beneficial effects of the utility model are that this device compresses tightly the sealing filler through pressing the cover, drives the clamp plate through clamp bolt and compresses tightly the pressure cover downwards to can adjust the degree of compaction of sealing filler, after the sealing filler wearing and tearing, adjust the sealing filler through adjusting clamp bolt, through the spring, can make the sealing filler all the time have a decurrent power, thereby improve the sealing performance of sealing filler.
Drawings
Fig. 1 is a front view of the present invention.
Detailed Description
The following detailed description of the preferred embodiments of the present invention is provided in connection with the accompanying drawings. As shown in fig. 1, an adjustable shaft hole sealing packing structure comprises a pressure plate 1, a pressure sleeve 2, a sealing packing 3 and a pressure bolt 4; the sealing packing is arranged in a shaft hole between the valve shaft 5 and the valve body 6, the pressing sleeve is sleeved on the valve shaft and pressed on the upper part of the sealing packing, the pressing plate is arranged on the pressing sleeve, and the pressing bolt penetrates through the outer side of the pressing plate and is in threaded connection with the top of the valve body. The top of the compression bolt is provided with a nut, a spring 7 is arranged between the nut and the pressing plate, and the spring is sleeved on the compression bolt. The spring always gives a downward force to the pressure plate, and the pressure sleeve is always kept to compress the sealing filler downwards, so that the sealing property of the sealing filler is improved. In the present invention, the contact surface between the pressing plate and the pressing sleeve is an inclined surface.
This device compresses tightly the sealing filler through pressing the cover, drives the clamp plate through housing bolt and compresses tightly the pressure cover downwards to can adjust the degree of compaction of sealing filler, after the sealing filler wearing and tearing, adjust sealing filler through adjusting housing bolt, through the spring, can make sealing filler all have a decurrent power all the time, thereby improve sealing filler's sealing performance.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
