Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
As Figure 1-3, the three-way control valve described in this utility model embodiment, including upper valve body 5, lower valve body 25 and company
It is connected on the bonnet, 9 at described upper valve body 5 top, between described upper valve body 5 and described lower valve body 25, lower valve base 4 is installed, in institute
It is positioned at described lower valve base 4 in stating upper valve body 5 and is arranged above upper valve base 6, described lower valve base 4 is provided with bottom spool 24, described
Being provided with upper valve core 22 on upper valve base 6, connecting between described upper valve core 22 and described bottom spool 24 has valve rod 23, described valve rod 23
Upper end be connected with described upper valve core 22, the lower end of described valve rod 23 is connected with described bottom spool 24, described upper valve core 22 upper end
Being provided with polished rod 8, described polished rod 8 penetrates in described bonnet, 9, is provided with filler between described bonnet, 9 and described polished rod 8.
In this example, described upper valve core 22 and described bottom spool 24 are tubular structure.
In this example, described upper valve core 22 and described bottom spool 24 side are equipped with sieve aperture.
The employing lower end sieve mesh type tubular structure of spool, thus avoid the fluid impulsive force directly to valve rod.And spool
Use the design (upper valve core and bottom spool) that two cylinder-symmetrical are installed, when one tubular spool of fluid impact can produce one
Planting outbreak and firmly act on another tubular spool, the force direction on two spools is contrary, makes the power of whole spool mutually support
Disappear, again reduce the fluid impulsive force to valve body.This valve rod valve core inside regulation flow design, simple in construction, and
Effectively avoid the impulsive force of fluid, thus substantially increase the service life of high pressure difference limen.
Further, in this example, described upper valve core 22 is externally provided with sleeve 7 and fairlead 19.Fairlead plays guiding and lubrication
Effect.
Further, in this example, between described lower valve base 4 and described lower valve body 25 and described upper valve body 5, it is equipped with first
Graphite wound gasket 3；The second graphite wound gasket 21 it is provided with between described upper valve base 6 and described upper valve body 5.
Further, in this example, between polished rod 8 and the described bonnet, 9 on described upper valve core 22, it is provided with filler set 15, institute
State filler set 15 bottom and described bonnet, 9 between be provided with the 3rd graphite wound gasket 18, described filler overlap 15 sides with described on
It is provided with O 17 between valve gap 9, is provided with described filler between described polished rod 8 and described filler set 15, is provided with below described filler
Filler heelpiece 10, described filler is arranged over gland 13, and described gland 13 top is provided with dust ring 12, described filler
Including two piece of first filler 14 and three piece of second filler 16, described three piece second fill out 16 material be positioned at described two piece of first filler 14 it
Between.Filler can play good lubrication and sealing function.
Concrete assemble sequence is as follows:
Operation one:
Pick up upper valve core, valve rod is screwed into inside upper valve core.
Operation two:
Join the cylinder pin hole beaten on valve rod according to hole reserved on upper valve core, after having beaten hole, straight pin pounded after in hand-hole,
