Description
Technical field
The present invention relates to a kind of leak free mutual inductor on site Fill valve and using method, belong to mutual inductor manufacturing technology field.
Background technique
At present, oil immersion type mutual-inductor is safeguarded at the scene or during after sales service, is usually utilized expander air relief cock, oil filler pipe and vacuum tube to carry out repairing.The problem that background technique exists is: the 1. non-special-purpose oil compensating tool of air relief cock, leak greatly, and careless manipulation is very easily deposited gas; 2. all want forvacuum before the repairing, loaded down with trivial details; 3. owing in the expander positive pressure is arranged, air relief cock all can oil spilling during the disassemble or assemble oil filler pipe.
Summary of the invention
The purpose of this invention is to provide a kind of leak free mutual inductor on site Fill valve and using method, during the on-the-spot repairing of oil immersion type mutual-inductor, do not destroy separately oiling under the state of vacuum or pressure, need not special-purpose oiling instrument, exempt from forvacuum, easy to use and flexible is without leakage, without depositing gas, be applicable to power plant maintenance and after sales service, solve the problems referred to above that background technique exists.
Technological scheme of the present invention is: a kind of leak free mutual inductor on site Fill valve, comprise four-way valve body, spool and seal ring, the four-way valve body setting is four passages up and down, spool is arranged in the four-way valve body by upper channel, the three seals circle is set on the valve body, the first seal ring is arranged on the spool bottom, mates with the lower channel inner port of four-way valve body, the second seal ring is arranged on the spool middle part, slides in the upper channel of four-way valve body, and the three seals circle is arranged on spool top, mates with the upper channel external port of four-way valve body.
The lower channel of four-way valve body is connected with the expander on mutual inductor top, and the left passage of four-way valve body or right passage connect the repairing pipe.If vacuumize first before the repairing, the left passage of four-way valve body be connected passage and connect respectively repairing pipe and vacuum-pumping tube.
The present invention is the two conducting structures of three sealings, and when having realized that equipment is safeguarded at the scene, repairing process and vacuum pressure are without leakage.
A kind of using method of leak free mutual inductor on site Fill valve, use above-mentioned on-the-spot Fill valve, comprise following steps: 1. before the on-the-spot repairing, confirm that first the surface of contact sealing of the three seals circle between four-way valve body and the spool is intact, check simultaneously the surface of contact sealing of first seal ring; 2. the lower channel of four-way valve body is connected with the expander on mutual inductor top, and the left passage of four-way valve body or right passage connect the repairing pipe; 3. the spool of outwarding winding; 4. then open oil pump, by the oiling in the mutual inductor of repairing pipe; 5. after oil level reaches the requirement of regulation, close oil pump and stop oiling, tighten spool; 6. the external oil pipe of dismantling.
Use the present invention, because good seal performance, can save repairing crosses the Cheng Qian and vacuumizes link, but, if need to or guarantee quality of product, can also vacuumize before the repairing process, operating procedure is as follows: the left passage of four-way valve body be connected passage and connect respectively repairing pipe and the vacuum-pumping tube spool of outwarding winding, then open vacuum pump and take out vacuum half an hour; Then open oil pump, by the oiling in the mutual inductor of repairing pipe; After oil level reaches the requirement of regulation, close oil pump and stop oiling, tighten spool; Dismantle external oil pipe and vacuum-pumping tube.
When outwarding winding spool, the first seal ring leaves the lower channel inner port of four-way valve body, the three seals circle leaves the upper channel external port of four-way valve body, the second seal ring that passes through between spool and the four-way valve body seals at this moment, the second seal ring slides in the upper channel of four-way valve body, but the upper channel external port of can not sliding out.
After tightening spool, the first seal ring compresses the lower channel inner port of four-way valve body, and the three seals circle compresses the upper channel external port of four-way valve body, and the second seal ring seals in the upper channel of four-way valve body, at this moment, the above-mentioned three seals circle that passes through between spool and the four-way valve body seals.
Make cost of material for saving, when outwarding winding spool, the maximum vertical penetration of second seal ring is positioned at upper channel external port place just, when can when upper channel external port place sees the second seal ring, stopping immediately the turn spool.
Good effect of the present invention: when 1. after sales service or user safeguard voluntarily to equipment, need not to rely on the special-purpose oiling frock of equipment manufacturing, flexible, workable; 2. between spool and the valve body three seals is arranged, can perfectly solve whole oiling process and keep the interior vacuum of equipment or pressure without leakage; 3. easy to use, can also save repairing and cross the Cheng Qian and vacuumize link.
