Abstract
The utility model discloses an on-line repair device for damage of a screw nut of a manual gate valve, which comprises a circular ring, wherein the circular ring consists of two semicircular rings, the inner side of a processed nut is provided with an internal thread, and the thread is matched with the thread of a gate valve screw; and fixing the circular ring outside the processed nut groove, similar to the structure of the original nut. The utility model discloses effectively solved the pipe network system, because main part equipment continuous production, the valve of repairing or changing can't be amputated, carry out online restoration through the structure that improves screw-nut, not only prolonged the life of slide valve, practiced thrift the expense, guaranteed the normal production of system, moreover, find out solution method for maintenance from now on.
Description
Technical Field
The utility model relates to an online prosthetic devices of manual slide valve nut damage belongs to machinery.
Background
The coke oven gas gate valve on the blast furnace coal injection system can not be opened and closed after the valve lead screw nut is damaged. The various types of valves installed in the pipe network system of the Tai-Gai energy power plant are thousands, wherein, the five-blast-furnace coal injection DN125 flashboard valve is a coke-oven gas valve on the blast-furnace coal injection system, and the system can not be opened and closed after the valve screw nut is damaged. Due to the continuity of the blast furnace production, the valve cannot be cut off and replaced and only can be repaired on line. If process according to former nut structure, because the valve can not be disassembled, valve-stem nut can't install. Therefore, the requirement of on-line installation can be met only by changing the structure of the nut.
Disclosure of Invention
The utility model aims at providing an online prosthetic devices of manual slide valve nut damage to the life of extension valve eliminates the equipment defect, ensures the production of main part equipment continuity.
The utility model adopts the technical proposal that: an online repair device for damage of a screw nut of a manual gate valve comprises a circular ring, wherein the circular ring consists of two semicircular rings, the inner side of a processed nut is provided with internal threads, and the threads are matched with the threads of a gate valve screw; and fixing the circular ring outside the processed nut groove, similar to the structure of the original nut.
In the device, a groove is formed in the position 10-15 mm above the damaged position of the screw rod nut of the manual gate valve, the thickness of the groove is equal to that of the ring, the ring is embedded into the groove, and the internal thread of the nut is matched with the thread of the screw rod.
Further, the outer diameter of the circular ring is 65mm, the inner diameter is 45mm, and the thickness is 10 mm.
The utility model discloses a change and be connected set nut bottom structure with the valve seat, realize under the condition that the pipe network normal operating does not influence the user and stop production, carry out on-the-spot equipment of fitting on line, solved valve screw nut base fracture fault, eliminated the pipe network and can't withdraw from the equipment hidden danger of operation restoration and change, guaranteed blast furnace main part gas equipment continuous production and protected the demand that supplies the operation.
The utility model provides an online prosthetic devices of manual slide valve nut damage, the beneficial effect who brings: the utility model discloses effectively solved the pipe network system, because main part equipment continuous production, the valve of repairing or changing can't be amputated, carry out online restoration through the structure that improves screw-nut, not only prolonged the life of slide valve, practiced thrift the expense, guaranteed the normal production of system, moreover, find out solution method for maintenance from now on.
The present invention will be further explained with reference to the drawings and examples.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic view of the installation position of the present invention.
In the figure, 1 is a circular ring, 2 is a screw nut, and A is the damaged position of the original nut.
Detailed Description
Example (b):
as shown in fig. 1 and 2, the online repair device for the damage of the screw rod nut of the manual gate valve comprises a circular ring 1, wherein the circular ring 1 consists of two semicircular rings, which are equivalent to a base of an original broken nut, the inner side of the nut 2 is provided with internal threads, and the threads are matched with the threads of the screw rod of the gate valve for use; and fixing the circular ring 1 outside the feed screw nut 2.
Among the above-mentioned device, damage position A top 10~15mm department at manual slide valve screw-nut and set up a recess, the thickness of recess equals with the thickness of ring, with this ring embedding this inslot, is equivalent to the base of original fracture nut, the cooperation is used.
Further, the outer diameter of the circular ring is 65mm, the inner diameter is 45mm, and the thickness is 10 mm.
The specific manufacturing method comprises the following steps:
a groove is formed 10-15 mm above a damaged position A of a screw nut of the manual gate valve. According to original fracture nut size, reprocess the nut, the nut of processing is longer 10mm than former nut, and corresponding former nut base position, the processing internal diameter is 45mm, and thickness is 10 mm's recess, and the thickness of recess equals with the thickness of ring, imbeds this inslot with this ring, is equivalent to the base of original fracture nut, and the cooperation is used.
During installation, the processed nut is screwed into the screw rod, the screwed depth passes through the valve nut positioning seat, the nut processing groove is exposed, then the two semicircular rings are embedded into the groove, namely the base of the original broken nut is equivalent, and then the nut and the positioning seat are locked and fixed to complete installation.
Claims (2)
