Embodiment
Below in conjunction with accompanying drawing, the present invention is described further.
One pushing open-close type Hexamermis spp valve as shown in Fig. 1 to 8, comprise an integrated main flow pipe 10, six roots of sensation tributary pipe 11 and a valve casing, structural strength and the sealing of one-body molded rear three can be strengthened greatly, valve casing is provided with seal ring 6, valve rod 3 and valve rod sealing device, valve rod 3 wears seal ring 6 and valve rod sealing device, valve rod 3 can rotate and move up and down, seal ring 6 belongs to conventional seals circle, for increasing the seal between valve casing and valve rod 3, liquid is avoided to flow out from the gap between valve rod 3 and valve body, valve rod sealing device is not only for the installation of valve rod 3, valve rod 3 is avoided to shake or come off, and control feel and the sealing of valve rod 3 further.Valve rod sealing device should move axially the requirement of rotating again for this valve rod 3, makes up the problem of common seal ring 6 performance deficiency.
The bottom of tributary pipe 11 is also provided with looped pipeline 110, and the sidewall of tributary pipe 11 is connected with main flow pipe 10 by looped pipeline 110.Spool 2 is provided with in tributary pipe 11, with valve opening 22 on spool 2, spool 2 can compress by the valve block 30 bottom valve rod 3, and move back and forth, spool 2 outer end is provided with spring 5, spring 5 is conflicted the opening of tributary pipe 11 and spool 2, for spool 2 provides an inside pressure, forces spool 2 inwardly to extrude.
In the movable process of spool 2, when the valve opening 22 of spool 2 is connected with looped pipeline 110, now spool 2 is pushed outwardly, and the fluid of main flow pipe 10 can flow through looped pipeline 110, spool 2 enters in tributary pipe 11.
The valve block 30 of the bottom of valve rod 3, is connected with handle 4 by valve rod 3, presses by handle 4 keying that pressure can control spool 2 in differentiated levels,
Valve rod 3 and valve block 30 are provided with oblique cooperation section, oblique cooperation section is the smooth curved surface such as fillet or chamfering, and oblique cooperation section can coordinate with the fillet on the top 21 of spool 2 or chamfering, realizes the movable compression of spool 2, prevent valve block 30 in mobile journey, spool 2 is stuck and cannot stretches.
As shown in Figure 5, the opening of tributary pipe 11 is provided with baffle ring 111, baffle ring 111 is also provided with the barrel 112 of the annular preventing spring 5 from deviating from, and barrel 112 edge inside tributary pipe 11 is stretched.The effect of baffle ring 111 strengthens fixing of spring 5, and the effect of barrel 112 is that spring 5 is fixed on tributary pipe 11 inwall, increases its fixed effect.
As shown in Fig. 2, Fig. 7 and Fig. 8, above-mentioned valve casing is also arranged with the valve rod sealing device for sealed valve stem 3, above-mentioned valve rod 3 cross section is rounded.
Valve rod sealing device comprise be enclosed within sleeve 7 outside valve rod, sealed valve stem filler 72, for compressing casting die 73 and the hold-down mechanism 8 of filler.And sleeve 7 comprises upper bush 71 and lower sleeve 74.Filler 72 and casting die 73 are all between upper bush 71 and lower sleeve 74, and because valve rod 3 is the rounded polished rods in cross section, filler 72 also surrounds annular, is positioned at outside valve rod 3.And casting die 73 inside portion is against filler 72 periphery, casting die 73 lateral part is provided with the first curve slope 731, and lower sleeve 74 is provided with the second curve slope coordinated with casting die 73 lateral part.Hold-down mechanism 8 is for the hold down gag by described upper bush 71 and the axial pressing of lower sleeve 74.When hold-down mechanism 8 compresses, order about described casting die 73 radial compaction filler 72 by curve slope.In order to ensure that the madial wall of casting die 73 can be radial to central pressing filler 72, casting die 73 is preferably made up of multiple arcuate member surrounding ring.Certain casting die 73 also can be an open loop.
The second flange 741 that above-mentioned hold-down mechanism 8 comprises the first flange 711 that upper bush 71 radial direction protrudes, lower sleeve 74 radial direction is protruded and multiple fastening piece for fastening first flange 711 and the second flange 741.Each described fastening piece includes turnbuckle 81 and screw rod 80, first flange 711 is provided with the through hole that diameter is greater than screw rod 80, the second flange 741 that through hole is corresponding is provided with the tapped hole mated with described screw rod 80, and screw rod lower end is threaded on the second flange 741 by tapped hole.Turnbuckle 81 is screwed in screw rod 80 top through through hole, and screw rod 80 part between the first flange 711 and turnbuckle 81 is nested with Compress Spring 82.
When screwing turnbuckle 81, turnbuckle 81 pressing Compress Spring 82, makes the first flange 711 and the second flange 741 axial compression, thus makes upper bush 71 and the axial pressing of lower sleeve 74.Casting die 73 lateral part is provided with the first curve slope 731, is specifically positioned at the downside of casting die 73 lateral part, and what be mated is the second curve slope of lower sleeve 74.The below that valve rod 3 stretches into belongs to one end of needs sealing, and top belongs to extraneous, and the sagittal plane corresponding to above-mentioned first curve slope 731 is positioned at the bottom of filler 72, and therefore, object is in order to the impacting force of the filler 72 near sealed end is greater than away from sealed end.As shown in Figure 9, the location comparison that the impacting force of filler 72 is maximum is little, and near sealing liquid regional seal end good sealing effect, in turn ensure that the activity performance of valve rod 3.
Above-mentioned upper bush 71 is also provided with the charging hole 712 of bonding pad 72, charging hole 712 is axially arranged.
The above makes the preferred embodiment of the present invention, and under not departing from the prerequisite of the principle of the invention for the person of ordinary skill of the art, can also make some modification and improvement, these also should be considered as protection scope of the present invention.
