Description
Technical Field
The utility model relates to a mouth of pipe plugging device specifically is a lining equipment mouth of pipe plugging device.
Background
At present, in the chemical industry, lining equipment is mostly used for chemical reaction, transportation, heat exchange, storage and other purposes of corrosive media. Due to the strong corrosion action of corrosive media, the lining of the equipment is easy to damage and fall off during the use process, thereby affecting the normal use of the equipment and even leading to the rejection of the equipment.
The lining layer at the nozzle part of the common equipment is easy to damage and fall off, and the damage of the nozzle sealing surface can be improved by the measure of adding a protective sleeve. However, if the broken portion of the lining extends to the nozzle connection portion, the protective sleeve can not play a role in preventing leakage. In this case, it is common practice to add a rubber plug or to plug the damaged pipe orifice directly with cement. However, the rubber plug is not connected with other parts and is easy to fall off, and the daub is not firmly attached to the lining equipment and is easy to fall off, so when a certain pipe orifice of the lining equipment is damaged, the damaged pipe orifice must be plugged to ensure normal use of the lining equipment, the pipe orifice must be effectively sealed, and the firmness and reliability of the plugging device must be ensured.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a lining equipment mouth of pipe plugging device can realize reliable shutoff.
The utility model provides a technical scheme that its technical problem adopted is:
a lining equipment pipe orifice plugging device comprises a pull rod bolt, a locking nut, a pull rod protective sleeve, an outer sleeve and an inner sleeve, wherein the locking nut is used for screwing the pull rod bolt; the pull rod protective sleeve is provided with an internal thread matched with the pull rod bolt; the outer sleeve comprises an outer sleeve bolt hole formed in the middle part of the outer sleeve, a pull rod bolt fixing groove arranged at the top end of the outer sleeve bolt hole and used for fixing a bolt head, a pull rod bolt fixing groove arranged at the top end of the outer sleeve bolt hole and used for fixing the bolt head, and an inner sleeve mounting hole with internal threads and arranged at the bottom of the outer sleeve; the upper half part of the inner sleeve is provided with an external thread matched with the internal thread of the inner sleeve mounting hole.
Adopt above-mentioned technical scheme the utility model discloses, compare with prior art, have following advantage:
(1) the pull rod bolt is fixed with the pipe orifice blind plate outside the pipe orifice of the equipment through the locking nut, so that the fixing is firm and the pull rod bolt is not easy to fall off;
(2) the outer sleeve and the inner sleeve are used for sealing, so that reliable plugging is realized, and leakage is not easy to generate;
(3) the service life of the lining equipment is prolonged;
(4) the plugging device has low manufacturing cost, meets the process requirements and has wide market.
Preferably, the present invention further provides:
the top of the outer sleeve is processed into an arc shape.
The top end of the inner sleeve is provided with a groove, and an O-shaped sealing ring is arranged in the groove.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
FIG. 2 is a schematic view of the construction of the jacket;
FIG. 3 is a schematic structural view of the inner sleeve;
in the figure: a draw bar bolt 1; a lock nut 2; a pull rod protective sleeve 3; a jacket 4; an inner sleeve 5; an outer sleeve bolt hole 6; a tie rod bolt fixing groove 7; an inner sleeve mounting hole 8; the top end of the inner sleeve is provided with a groove 9.
Detailed Description
The invention will be described in detail with reference to the accompanying drawings and examples for better understanding.
Referring to fig. 1-3, the pipe orifice plugging device for lining equipment disclosed in this embodiment is composed of a stay bolt 1, a lock nut 2, a stay protective sleeve 3, an outer sleeve 4 and an inner sleeve 5, wherein the top of the stay bolt 1 is a bolt head, the upper part of the bolt is a smooth rod body, and the lower part of the bolt is provided with an external thread. The pull rod protective sleeve 3 is made of corrosion-resistant materials and is provided with internal threads matched with the external threads of the pull rod bolt 1. The top of the outer sleeve 4 is processed into an arc, and the radian of the arc is consistent with that of the inner wall of the equipment outside the pipe orifice and is tightly attached to the inner wall of the equipment. The middle part of the outer sleeve 4 is provided with an outer sleeve bolt hole 6 for inserting the pull rod bolt 1; and a bolt fixing groove 7 for fixing a bolt head is arranged below the outer sleeve bolt hole 6, and an inner sleeve mounting hole 8 and internal threads are arranged at the bottom of the outer sleeve 4. The upper half part of the inner sleeve 5 is provided with an external thread matched with the internal thread of the outer sleeve mounting hole 8, the top end of the inner sleeve is provided with two circles of grooves 9, and an O-shaped sealing ring is arranged in each groove 9 so as to be matched with the top end surface of the inner sleeve mounting hole 8 in a sealing mode.
During operation, insert the pull rod bolt 1 in the overcoat bolt hole 6, in this embodiment, the length of overcoat bolt hole 6 is half of the length of pull rod bolt 1, and the bolt head is fixed in pull rod bolt fixed slot 7, and the other end of pull rod bolt 1 and pull rod protective sheath 3 threaded connection to stretch out pull rod protective sheath 3.
