The beneficial effects of the utility model are: owing to being equipped with thread bush free to rotate in installing rack, plug core is embedded in thread bush by the screw thread arranging on it, thread bush is provided with rotation lifting handle, plug core top is provided with reversing handle, when opening plug core, first rotate and upgrade handle, then rotate reversing handle, make to fill in the power of using when core is opened and greatly reduce; Solved directly rotate in the past reversing handle can not open immediately plug core,
The situation that occurs jam.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of filling in core in the utility model and opening the parts of plug core.
In Fig. 1 to Fig. 2: 1. body, 101. oil-ins, 102. oil-outs, 103. oil suction chambers, 104. go out oil pocket, 2. filter vat, 21. handles, 3. upper cover, 4. pin type vent valve, 5. drainage bolt, 6. fills in core, 7. gland, 8.O shape sealing ring, 9. installing rack, 10. thread bush, 11. rotate lifting handle, 12. reversing handles.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 1-2, a kind of low pressure coarse oil screen, comprise body 1, body 1 is provided with oil-in 101 and oil-out 102, in body 1, be also provided with oil suction chamber 103 and go out oil pocket 104, oil suction chamber 103 and going out between oil pocket 104 is connected by two filter vats 2 that are arranged in body 1, and filter vat 2 is provided with handle 21.On body 1, above filter vat 2, be removably provided with upper cover 3, on upper cover 3, in the position corresponding to filter vat 2, be provided with pin type vent valve 4.On described body 1, near base plate place, be provided with relief outlet, in described relief outlet, be threaded connection drainage bolt 5.In described body 1, be provided with for control the rotary plug core 6 of oil-in 101 and oil-out 102 break-makes simultaneously, plug core 6 is provided with liquid outlet channel, plug core 6 is inverted cone-shaped with the part that oil-in 101 and oil-out 102 match, body 1 is provided with the gland 7 of limit plug core 6, plug core 6 tops pass from gland 7, and gland 7 and 6, core of plug are provided with twice O-ring seals 8.Gland 7 is provided with installing rack 9, is equipped with thread bush free to rotate 10 in installing rack 9, and plug core 6 is embedded in thread bush 10 by the screw thread arranging on it, and thread bush 10 is provided with and rotates lifting handle 11, and plug core 6 tops are provided with reversing handle 12.
When opening plug core 6, first rotate and upgrade handle, thread bush 10 rotates thereupon, because plug core 6 is embedded in thread bush 10 by the screw thread arranging it on, the rotation of thread bush 10 forces fills in the core 6 micro-stroke that moves upward, because bottom is inverted cone-shaped, after moving upward and between valve body, produce space, rotate so reversing handle 12, the power of using when plug core 6 is opened reduces greatly again, is easy to the just rotatable plug core 6 of opening.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not for limiting the utility model; It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
