Abstract
A kind of Underearth oil tanks is pumped double-deck bottom valve, be made up of upper valve body (2) and lower valve body (4), upper valve body spool (3) is provided with in upper valve body (2), lower valve body spool (5) is provided with in lower valve body (4), upper valve body upper end is connected with oil feed line by loose joint nut (1), lower valve body (4) lower end is provided with oil sucting cavity (6), upper valve body (2) and lower valve body (4) adopt be threaded integral.To pump double-deck bottom valve with Underearth oil tanks described in the utility model, reach double-sealing function, effectively prevent spool jam, and rate of fault is extremely low, prevent the oil in oil feed line from leaking back in Underearth oil tanks, make oil pump smooth delivery of power oil.
Description
Technical field
The utility model belongs to the annex in oil supply system, and a kind of Underearth oil tanks is pumped double-deck bottom valve specifically.
Background technique
The bottom valve of Underearth oil tanks plays vital effect in oil supply system, and the bottom valve of current Underearth oil tanks still can not meet double-sealing function simultaneously and prevent jam, and rate of fault is high.
Summary of the invention
The purpose of this utility model is for deficiency of the prior art, there is provided one to have double-sealing function, effectively prevent oil from leaking, can keep being full of oil in pump inlet pipe and the pump housing, make oil pump smooth delivery of power oil, the double-deck bottom valve and the extremely low Underearth oil tanks of rate of fault is pumped.
The utility model is a kind of Underearth oil tanks bottom valve, be made up of upper valve body and lower valve body, upper valve body spool is provided with in upper valve body, lower valve body spool is provided with in lower valve body, upper valve body upper end is connected with oil feed line by loose joint nut, lower valve body lower end is provided with oil sucting cavity, upper valve body and lower valve body adopt be threaded integral
As optimal technical scheme of the present utility model:
Described oil sucting cavity installs filter screen additional, prevents impurity from entering pipeline.
The application a kind ofly meets double-sealing function simultaneously, can effectively prevent spool jam and the extremely low bottom valve of rate of fault, prevents the oil in oil feed line from leaking back in Underearth oil tanks, makes oil pump smooth delivery of power oil.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is plan view of the present utility model.
In figure: 1-loose joint nut, 2-upper valve body, 3-upper valve body spool, valve body under 4-, valve body spool under 5-, 6-oil sucting cavity.
Embodiment
Now with regard to accompanying drawing 1-2 and embodiment, the utility model is further described.
A kind of Underearth oil tanks is pumped double-deck bottom valve, be made up of loose joint nut 1, upper valve body 2, upper valve body spool 3, lower valve body 4, lower valve body spool 5, oil sucting cavity 6, upper valve body 2 upper end is connected with loose joint nut 1, loose joint nut adopts with oil feed line and is threaded, lower valve body 4 lower end is provided with oil sucting cavity 6, oil sucting cavity 6 installs filter screen additional, upper valve body 2 and lower valve body 4 adopt be threaded integral.Whole valve body is connected with oil feed line by loose joint nut 1, when pump start, negative pressure is formed in oil pipe, make pressure in lower valve body 4 higher than the pressure in upper valve body 2, lower valve body spool 5 upwards lifts under the impact of two-way pressure difference, again by upper valve body spool 3 jack-up, oil sucks oil supply pipeline from Underearth oil tanks, when the pump stops, negative pressure in upper valve body disappears, and becoming malleation due to the pressure in oil pipe, upper valve body spool and lower valve body spool are automatically closed under the effect of malleation, effectively prevent the oil in oil pipe to be back to Underearth oil tanks.
Claims (2)
1. a Underearth oil tanks is pumped double-deck bottom valve, it is characterized in that, be made up of upper valve body (2) and lower valve body (4), upper valve body spool (3) is provided with in upper valve body (2), lower valve body spool (5) is provided with in lower valve body (4), upper valve body (2) upper end is connected with oil feed line by loose joint nut (1), and lower valve body (4) lower end is provided with oil sucting cavity (6), upper valve body (2) and lower valve body (4) adopt be threaded integral.
2. Underearth oil tanks according to claim 1 is pumped double-deck bottom valve, and it is characterized in that, (6) install filter screen additional to described oil sucting cavity.
