Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provide a kind of overhaul simultaneously also can the maintenance of control valve break-make time band on-off function valve.
The purpose of this utility model realizes by following technical proposal: a kind of valve of band on-off function when overhauling, comprise valve body, valve gap, spool, valve rod and handle, described spool is arranged in valve body, valve rod one end is connected with handle, the other end is connected with spool, described valve gap is fixed on valve body, and valve rod and valve gap are spirally connected, fluid passage is provided with in described valve body, it is characterized in that: also comprise maintenance spool, valve body is provided with the setting bath for holding maintenance spool, maintenance spool top is provided with connecting rod, and described maintenance spool is connected to bottom spool by connecting rod is dismountable, described valve gap forms annular shoulder block between valve gap and valve body, and make described spool be against on shoulder block by rotary valve rod, now overhaul spool and be positioned at setting bath, connecting rod is positioned on described fluid passage, and described fluid passage is opened, also spool shutoff fluid passage can be made by rotary valve rod, now described maintenance spool is positioned at setting bath bottom land, described setting bath bottom land is provided with positioning spiro pit, the fixed hole coaxial with positioning spiro pit is provided with bottom maintenance spool, also comprise the externally threaded maintenance screw rod of band, described maintenance screw rod end has fixed block, and described maintenance screw rod to be screwed onto on positioning spiro pit and to be fixed with maintenance spool by the cooperation of fixed hole and fixed block.
When valve normally uses, make spool be against on shoulder block by rotary valve rod, now connecting rod is positioned on fluid passage, and fluid passage is opened, or rotary valve rod makes spool shutoff fluid passage; During maintenance, maintenance screw rod is screwed onto on positioning spiro pit and is fixed with maintenance spool by the cooperation of fixed hole and fixed block, to be separated with spool by connecting rod afterwards and valve gap, spool, valve rod and handle together to be dismantled from valve body keep in repair, overhaul screw rod afterwards to continue rotate upward on positioning spiro pit and make maintenance spool shutoff fluid passage, or also can continue again to make maintenance spool open fluid passage upward, therefore make this valve energy on-line maintenance by the cooperation of maintenance spool and maintenance screw rod.
As preferably, described positioning spiro pit is provided with sealing plug, and described sealing plug and positioning spiro pit are spirally connected.
During normal use, sealing plug and positioning spiro pit are spirally connected to prevent valve internal from entering impurity.
As preferably, described fixed hole is inner hexagonal hole, and described fixed block is the outer-hexagonal block mated with fixed hole.
Therefore, after fixed hole is filled in fixed block cooperation, by rotary spool, spool is easily separated from connecting rod.
As preferably, described connecting rod is screwed onto bottom spool.
Compared with prior art, the utility model tool has the following advantages:
When valve normally uses, make spool be against on shoulder block by rotary valve rod, now connecting rod is positioned on fluid passage, and fluid passage is opened, or rotary valve rod makes spool shutoff fluid passage; During maintenance, maintenance screw rod is screwed onto on positioning spiro pit and is fixed with maintenance spool by the cooperation of fixed hole and fixed block, to be separated with spool by connecting rod afterwards and valve gap, spool, valve rod and handle together to be dismantled from valve body keep in repair, overhaul screw rod afterwards to continue rotate upward on positioning spiro pit and make maintenance spool shutoff fluid passage, or also can continue again to make maintenance spool open fluid passage upward, therefore make this valve energy on-line maintenance by the cooperation of maintenance spool and maintenance screw rod.
