Abstract
The utility model discloses a free movable lubrication throttle valve which comprises a valve body, a valve core, an oil inlet and an oil outlet. The valve core is arranged between the oil inlet and the oil outlet, an upper spring and a lower spring are respectively arranged on the upper part and the lower part of the valve core, elastic pressure of the upper spring is larger than that of the lower spring. In order to fix the spring conveniently, a spring fixing hole is arranged on an upper opening of the valve core. In order to guarantee normal lubrication of the valve core and free passage of lubricating oil, definite gaps are retained on periphery of the valve core. The free movable lubrication throttle valve is not easy to block, can supply oil for lubrication reliably in a long time, guarantee free passage of lubricating system and prolong mechanical service life of the lubrication throttle valve.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of without hindrance mobile lubrication throttle valve.
Background technique
Lubricated throttle valve has a variety of, but general service time time not length will stop up, not fuel-displaced, do not cause lubricated influence mechanical working life.
Summary of the invention
The purpose of this utility model is that a kind of difficult obstruction, the long-time proper lubrication fuel feeding of energy are provided for the deficiency that solves above-mentioned technology, guarantees the straightway a kind of without hindrance mobile lubrication throttle valve of lubrication system.
In order to achieve the above object, a kind of without hindrance mobile lubrication throttle valve that the utility model is designed, comprise valve body, spool, oil inlet hole and oil outlet, spool is located between oil inlet hole and the oil outlet, and at upper and lower upper spring and the lower spring of being respectively equipped with of spool, the elastic pressure of upper spring is greater than the elastic pressure of lower spring.For the ease of fixing of spring, at the spool spring fixed hole that is provided with suitable for reading.Lubricated normal in order to ensure spool, lubricant oil is unblocked, leaves definite space around the spool.Described upper spring and lower spring can be respectively cluster spring and single spring.Described spool can be the thread type spool.
During work, in outer oil duct, produce oil pressure, spool is pushed to, upper spring is compressed, when oil pressure was not worked, upper spring promoted spool under the effect of elastic force, and the lubricant oil friction around the spool is returned in the outer oil duct, leave the space around making spool, guarantee that next time is lubricated normally unblocked.
The resulting a kind of without hindrance mobile lubrication throttle valve of the utility model is difficult for obstruction, the long-time proper lubrication fuel feeding of energy, guarantees that lubrication system is unblocked, prolongs and finds pleasure in the mechanical working life of lubricating throttle valve.

Embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment 1
As shown in Figure 1, a kind of without hindrance mobile lubrication throttle valve that present embodiment is described, comprise valve body 1, spool 2, oil inlet hole 3 and oil outlet 4, spool 2 is located between oil inlet hole 3 and the oil outlet 4, at spool 2 upper and lower upper spring 5 and the lower springs 6 of being respectively equipped with, the elastic pressure of upper spring 5 is greater than the elastic pressure of lower spring 6.For the ease of fixing of spring, at spool 2 spring fixed holes 7 that are provided with suitable for reading.Lubricated normal in order to ensure spool 2, lubricant oil is unblocked, leaves definite space 8 around the spool 2.Described upper spring 5 and lower spring 6 can be respectively cluster spring or single spring.During work, in outer oil duct 9, produce oil pressure, lubricant oil by oil inlet hole 3 enter and valve body 1 in, spool 2 is pushed to, and upper spring 5 is compressed, when oil pressure is not worked, upper spring 5 promotes spool 2 under the effect of elastic force, lubricant oil friction around the spool 2 is returned to 9 li of outer oil ducts, leave certain space 8 around the spool, guarantee that next time is lubricated normally unblocked.The designed spool of present embodiment also can adopt thread type spool as shown in Figure 2.
