Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of deep seafloor valve.
Background technique
Because deep seafloor valve is applied in abyssal environment; the corrosive media of band such as mud are often covered with around it; therefore the outer end portion mud etc. that is easy and surrounding that valve rod passes outside valve gap is with Korrosionsmedium to mix; thus not only greatly affect the normal keying of valve; and these media also to valve rod itself and once enter in valve body with valve rod and all can bring infringement to each parts of valve inner, thus can shorten the whole service life of valve greatly.
Summary of the invention
For the deficiencies in the prior art, the utility model provides the deep seafloor valve that a kind of sealability is better, effectively can extend valve whole service life.
For achieving the above object, the utility model provides a kind of deep seafloor valve, comprise valve body, valve rod, valve gap, flap, described valve gap is installed on valve body, described flap is loaded in valve body, valve rod is arranged in valve gap, and the inner end that described valve rod enters in valve body through valve gap is connected with flap, described valve rod passes on the end, outer end outside valve gap and driving handwheel is housed, described valve rod passes in the outer end portion outside valve gap and is arranged with outer tube, the through hole that described valve gap passes for valve rod is cone structure wide at the top and narrow at the bottom, on the lower end of described outer tube, corresponding being provided with can form the lower end mouth of interference inserting with the upper conical through hole of described valve gap, and the joint of described outer tube lower end and valve gap conical through-hole is also provided with corrosion-resisting protecting jacket, the upper end of described corrosion-resisting protecting jacket to be set on outer tube lower end and spacing fixing by upper limit snap ring, the lower end of described corrosion-resisting protecting jacket to be set on valve gap and spacing fixing by lower limit snap ring, self-seal device is provided with between the upper end port of described outer tube and valve rod, described self-seal device includes V-type filler, seal ring, oil seal spring, gland, the lower end of described seal ring is provided with two extended legs, an oval cavity is formed between two extended legs, described oil seal spring is flush-mounted in described oval cavity, the corners of described V-type filler to be inserted in described oval cavity and is abutted with described oil seal spring, the terminal part of two extended legs then abuts with the inclined-plane, both sides of V-type filler respectively, described gland press-fits between outer tube and valve rod, and the axial limiting formed seal ring and V-type filler.
The beneficial effects of the utility model are: adopt said structure, to pass at described valve rod due to the utility model in the outer end portion outside valve gap and be arranged with outer tube, therefore can effectively to avoid in abyssal environment the band Korrosionsmediums such as mud directly and valve stem contacts, thus make valve rod protected, simultaneously, also corrosion-resisting protecting jacket is provided with in the joint of described outer tube lower end and valve gap, and self-seal device is provided with between the upper end port and valve rod of described outer tube, therefore the overall sealing performance of valve is not only improved further, but also effectively to avoid in abyssal environment the band Korrosionsmediums such as mud to enter in valve body with valve rod lifting, thus effectively extend valve whole service life.
The utility model can be set to also be provided with stuffing box packing between the middle part of described corrosion-resisting protecting jacket and outer tube and valve gap further.
Adopt said structure, the sealability of outer tube and valve gap joint can be promoted further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the I portion enlarged view of Fig. 1;
Fig. 3 is the II portion enlarged view of Fig. 1.
Embodiment
As Fig. 1, 2, a kind of deep seafloor valve is given shown in 3, comprise valve body 1, valve rod 2, valve gap 3, flap 4, described valve gap 3 is installed on valve body 1, described flap 4 is loaded in valve body 1, valve rod 2 is arranged in valve gap 3, and the inner end that described valve rod 2 enters in valve body 1 through valve gap 3 is connected with flap 4, described valve rod 2 passes on the end, outer end outside valve gap 3 and driving handwheel 5 is housed, described valve rod 2 passes in the outer end portion outside valve gap 3 and is arranged with outer tube 6, the through hole 31 that described valve gap 3 passes for valve rod 2 is cone structure wide at the top and narrow at the bottom, on the lower end of described outer tube 6, corresponding being provided with can form the lower end mouth 61 of interference inserting with the upper conical through hole 31 of described valve gap 3, and the joint of described outer tube 6 lower end and valve gap conical through-hole 31 is also provided with corrosion-resisting protecting jacket 7, the upper end of described corrosion-resisting protecting jacket 7 to be set on outer tube 6 lower end and spacing fixing by upper limit snap ring 71, the lower end of described corrosion-resisting protecting jacket 7 to be set on valve gap 3 and spacing fixing by lower limit snap ring 72, stuffing box packing 73 is also provided with between the middle part of described corrosion-resisting protecting jacket 7 and outer tube 6 and valve gap 3.Self-seal device 8 is provided with between the upper end port 62 of described outer tube 6 and valve rod 2, described self-seal device 8 includes V-type filler 81, seal ring 82, oil seal spring 83, gland 84, the lower end of described seal ring 82 is provided with two extended legs 821, an oval cavity 822 is formed between two extended legs 821, described oil seal spring 83 is flush-mounted in described oval cavity 822, the corners 811 of described V-type filler 81 to be inserted in described oval cavity 822 and is abutted with described oil seal spring 83, the terminal part 8211 of two extended legs 821 abuts with the inclined-plane, both sides 812 of V-type filler 81 respectively, described gland 84 press-fits between outer tube 6 and valve rod 2, and the axial limiting formed seal ring 82 and V-type filler 81.During embody rule, when valve rod 2 inaction, just can realize outer tube upper end port 62 by the seal ring 82 in described self-seal device 8 and seal with the normality of valve rod 2; And when valve rod 2 oscilaltion activity; the corners 811 of V-type filler 81 will promote oil seal spring 83 upwardly described oval cavity 822; thus impel two extended leg 821 radial expansions of seal ring 82 to strut; and then the sealing strengthened between outer tube upper end port 62 and valve rod 2; the band Korrosionsmediums such as mud are effectively avoided in abyssal environment to enter in valve body 1 with valve rod 2 oscilaltion; when valve rod 2 is stopped action, described self-seal device 8 is returned to again normality sealing.
Adopt said structure, to pass at described valve rod 2 due to the utility model in the outer end portion outside valve gap 3 and be arranged with outer tube 6, therefore the band Korrosionsmediums such as mud can be effectively avoided in abyssal environment directly to contact with valve rod 2, thus valve rod 2 is protected, simultaneously, corrosion-resisting protecting jacket 7 is also provided with in the joint of described outer tube 6 lower end and valve gap 3, and self-seal device 8 is provided with between the upper end port 62 and valve rod 2 of described outer tube 6, therefore the overall sealing performance of valve is not only improved further, but also effectively to avoid in abyssal environment the band Korrosionsmediums such as mud to be elevated with valve rod 2 and enter in valve body 1, thus effectively extend valve whole service life.
