Description
One. technical field: the utility model relates to oil suction filter in a kind of fuel tank, particularly relates to a kind of with oil suction filter in the case of self-styled valve.
Two. background technology: the oil suction filter can be under the situation that fuel tank is not drained the oil in the existing case, by the pull bar that links to each other with loam cake filter core is proposed, be convenient to very much bolt look into filter screen pollution level and can be in time renew cartridge more, therefore obtained increasing application, but because its oil-out is downward, directly identical with the fluid in the fuel tank, so it has a fatal weakness is also arranged: be exactly when leakage of oil need be changed if inlet port sealing ring or fuel sucking pipe damage, then must drain the oil time-consuming so not only but also effort.
Three. the content of utility model:
The purpose of this utility model: overcome the defective of prior art, provide a kind of reasonable in design, simple in structure, can realize oil suction filter in the self-packing case with self-styled valve.
The technical solution of the utility model: a kind of with oil suction filter in the case of self-styled valve, contain lower cover, filter core, pull bar and loam cake, lower cover wherein, filter core, pull bar is connected successively with loam cake, and, lower cover and the fuel tank inlet port is movable is tightly connected, loam cake and fuel tank are movable to be tightly connected, spool of suit in the endoporus of described lower cover, described spool is the hollow cavity of upper end closed lower ending opening, the sidewall of this hollow cavity is provided with at least one intercommunicating pore, be provided with position-limit mechanism and sealing mechanism between described spool and the described lower cover, described lower cover is provided with spring base, be placed with the lifting spring in the inner chamber of described spring base, this promotes the last end in contact of spring lower end and described spool, and the body wall of described spring base is provided with at least one intercommunicating pore.
Described position-limit mechanism is the outer shroud platform that is provided with on the described spool and the interior step end face that covers down, prevents that spool from falling into described inlet port; Described sealing mechanism is a sealing ring, and the sealing circle is arranged on the inner hole wall of described lower cover or/and on the outer wall of spool.Described sealing ring is two, and the inner hole wall that is separately positioned on described lower cover is or/and the both ends up and down of the outer wall of spool, is convenient to that spool moves up and down and seals when the high-low limit position.
Described spring base and lower cover are threaded, and the contact-making surface of the two is provided with sealing ring or/and sealing gasket.Intercommunicating pore on the described spool is more than three, and circumferentially; Intercommunicating pore on the described spring base is more than three, and is uniformly distributed along the circumference.Described intercommunicating pore is circular, or is oval, or is rectangle, or is square, or is trapezoidal, or is rhombus.
The beneficial effects of the utility model:
1. the utility model is provided with self-styled valve arrangement, can realize draining the oil, and only loam cake is taken apart promptly and automatically inlet port is sealed, and the fluid in the fuel tank can not flow out inlet port, can relievedly change inlet port seal or fuel sucking pipe easily.
2. the utility model spool outer wall and lower cover inner hole wall are provided with the O-ring seals sealing, and the effect of sealing ring has two: the one, and when guaranteeing that inlet port leads to oil, fluid only leads to oil-out through filter core; The 2nd, during the inlet port sealing, the guard box inner fluid can not leak into oil-out from here, guarantees the cleanliness factor of filter oil.
When 3, the utility model is taken loam cake apart, seal with filter core, pull bar, spring base and loam cake jack-up and with inlet port, need not mention artificially, be convenient to very much operation and laborsaving saving time by the elastic force that promotes spring.
4. the utility model spring base and lower cover adopt and are threaded, easy accessibility, and be provided with sealing ring or sealing gasket between the two, prevent leakage of oil effectively.Intercommunicating pore on spool and the spring base is a plurality of and is uniformly distributed along the circumference in addition, increases the flowing velocity and the uniformity of filter oil, and the intercommunicating pore on spool and the spring base can correspondingly be provided with, and increases its connectedness.
5, the utility model structural design is ingenious, does not worry that the fluid envelope is not dead or not smooth, and through experiment, operation and sealing effectiveness are good, and the scope of application is wide, has good economic and social benefit.
Four. description of drawings:
Fig. 1 is the structural representation with the detent position of oil suction filter in the case of self-styled valve;
Fig. 2 is the structural representation of putting with the logical oil level of oil suction filter in the case of self-styled valve.
Five. the specific embodiment:
Embodiment: referring to Fig. 1 and Fig. 2, among the figure, the 1-inlet port, the 2-lower cover, the 3-spool, 4-O shape sealing ring, the 5-spring base, 6-promotes spring, 7-filter core, 8-pull bar, 9-loam cake.
Position-limit mechanism is the outer shroud platform that is provided with on the spool 3 and the interior step end face on the lower cover 2, prevents that spool 3 from falling into inlet port 1; Sealing mechanism is a sealing ring 4, and sealing circle 4 is two, and the inner hole wall that is separately positioned on lower cover 2 is both ends up and down, is convenient to that spool 3 moves up and down and seals when the high-low limit position.Certainly sealing ring 4 also can be arranged on the outer wall two ends of spool, can also on lower cover 2 endoporus and spool 3 outer walls sealing ring 4 be set all, determines as required.
Intercommunicating pore on the spool 3 is more than three, and circumferentially; Intercommunicating pore on the spring base 5 is more than three, and is uniformly distributed along the circumference.Intercommunicating pore is circular, or is oval, or is rectangle, or is square, or is trapezoidal, or is rhombus.The quantity of intercommunicating pore and shape are determined as required.
During work, loam cake is by being bolted on the fuel tank, and lower cover 2 contacts with inlet port 1, and inlet port 1 is with spool 3 jack-up, and promote spring 6 and be compressed this moment, and the intercommunicating pore on spool 3 and the spring base 6 is interconnected, and fluid enters inlet port 1 through the filtration of filter core 7.When needs are changed sealing mechanism, the bolt of loam cake 9 is removed, the elastic force that promotes spring 6 need not be mentioned artificially with filter core 7, pull bar 8, spring base 6 and loam cake 9 jack-up and with inlet port 1 sealing, is convenient to very much operation and laborsaving saving time.In addition, the intercommunicating pore on spool 3 and the spring base 6 is not communicated with, and inlet port 1 is closed, and the fluid in the fuel tank can not flow out inlet port 1, can relievedly change inlet port seal or fuel sucking pipe easily.
Change spool specific constructive form, the concrete syndeton that changes the concrete structure of position-limit mechanism and sealing mechanism and change spring base and lower cover can form a plurality of embodiment, be common excursion of the present utility model, do not describe in detail one by one at this.
