It is intended to.
Fig. 3 is a kind of off position signal of Combination filter element of the valve block installing type with by-passing valve provided by the utility model
Figure.
Specific embodiment
Below according to FIG. 1 to FIG. 3, the preferred embodiment of the utility model is illustrated.
As shown in FIG. 1 to 3, the utility model provides a kind of Combination filter element of the valve block installing type with by-passing valve, includes:
Filter core；
Valve body 4 is bypassed, is threadedly coupled with filter core, which is internally provided with circlip 10, and circlip 10 is set
It sets in the upside of the side port 13 of bypass valve body 4；
Valve seat 7, setting are located at 4 lower section of circlip inside bypass valve body 4, can move along the radial of bypass valve body 4
It is dynamic；
Spool 6 is arranged inside valve seat 7, can be along moving radially for valve body 4 is bypassed, and the top of the spool 6 is provided with
Valve core nut 8；
Spring assembly is arranged on spool 6, provides the back stretch moved radially for spool 6 and valve seat 7.
Further, the filter core includes:
Filter core bottom plate 1；
Filter core main body 2, it is netted in cylinder；
Filter core interface 3 is used to connect filter core main body 2 and bypass valve body 4.
The spring assembly includes:
First spring 11 is arranged on spool 6, when spool 6 moves in bypassing valve body 4, first spring 11
Back stretch is provided；
Second spring 12 is arranged on spool 6, when valve seat 7 moves in bypassing valve body 4, the second spring 12
Back stretch is provided.
In order to completely cut off oil inlet and oil return completely, guarantee the cleaning of oil liquid, in the contact of filter core interface 3 and bypass valve body 4
First sealing ring 5 is set on face, second sealing ring 9,5 He of the first sealing ring are set on the outer wall of bypass valve body 4
O-ring seal all can be used in second sealing ring 9.
The working principle of the utility model is as follows:
When valve block oil inlet, Combination filter element is in positive working condition at this time, as shown in Figure 1, oil liquid passes through filter from the outside
Core main body 2 enters inside Combination filter element, under oil liquid pressure effect, spool 6 is jacked up upwards, opening 14 of the oil liquid from spool 6
Flow to the oil inlet 15 of valve block；
When valve block oil return, Combination filter element is in reversed bypass state at this time, as shown in Fig. 2, oil liquid is acted on from above
On spool 6, the first spring 11 and second spring 12 are compressed downwards, so that spool 6 moves downward, while driving valve seat 7 downward
Movement, until the lower surface of spool 6 is contacted with bypass valve body 4, oil liquid passes through the side port opened of bypass 4 upper surface of valve body at this time
13 flow out outward, to realize oil liquid oil return；
When valve block does not work, as shown in figure 3, the pressure of 6 upper and lower surface of spool is equal, spool 6 is in 11 He of the first spring
Under second spring 12 acts on, 7 upper surface of valve seat is withstood in the lower surface of locking nut 8, the upper surface of valve seat 7 withstand circlip 10 to
Realize balance.
Three kinds of working conditions of Combination filter element are all mutually coordinated with the work of valve block, and every kind of working condition is all by passing through spring
Compression realize.
A kind of valve block installing type provided by the utility model is set to underwater oil exploitation system with the Combination filter element of by-passing valve
System can provide simple and more efficiently filtering when deep-sea oil gas resource is developed for system hydraulic oil.
It is discussed in detail although the content of the utility model has passed through above preferred embodiment, but it should be appreciated that on
