Detailed Description
The following description will specifically describe the contact pin type switch for fluid according to the present invention with reference to the accompanying drawings.
Referring to fig. 1, the utility model discloses a contact pin formula switch for fluid, including switch body 6, establish through-hole 5 in switch body, the right-hand member diameter that through-hole 5 is located switch body 6 reduces into pinhole 12, establishes foraminiferous separating platform 8 in through-hole 5, separates platform 8 and cuts apart into two parts about with through-hole 5. An end cover 3 is arranged at the left end of the switch body 6, and the end cover 3 can be fixed on the switch body 6 through screws. A shoulder 1 is arranged on the surface of the end cover 3 facing the through hole 5, a spring 4 is arranged in the through hole between the end cover 3 and the partition table 8, one end of the spring 4 is sleeved on the shoulder 1, a stainless steel ball 13 is arranged at the other end of the spring 4, a partition table sealing ring 7 is arranged on the surface of the partition table facing the end cover 3, and the diameter of the steel ball 13 is larger than the aperture of the partition table sealing ring 7. The switch body 6 is provided with a fluid inlet 14, and the fluid inlet 14 is communicated with a through hole between the end cover 3 and the partition table 8. A pin 11 is inserted into a pin hole 12 at the right end of the switch body 6. The switch body 6 is provided with a fluid outlet 9, and the fluid outlet 9 is communicated with a through hole between the partition 8 and the pinhole 12.
In order to prevent that fluid from flowing from switch body 6's through-hole both ends, the utility model discloses establish circular bead sealing washer 2 on circular bead 1, circular bead sealing washer 2's external diameter and through-hole 5's aperture looks adaptation. A pinhole sealing ring 10 is also arranged in the pinhole 12, and the outer diameter of the pinhole sealing ring 10 is matched with the aperture of the pinhole 12.
In use, the fluid inlet 14 is connected to a fluid inlet pipe and the fluid outlet 9 is connected to a fluid outlet pipe. After the fluid enters the through hole 5, the steel ball 13 is firmly pressed against the partition sealing ring 7 due to the action of the spring 4, and the fluid is blocked from flowing to the fluid outlet 9. When the insert pin 11 is inserted into the needle hole 12 and abuts against the steel ball 13 to separate the steel ball 13 from the partition sealing ring, the fluid flows out from the fluid outlet 9 through the holes on the partition sealing ring 7 and the partition 8 because the fluid has no hole and cannot enter the fluidity. The utility model discloses the accessible is adjusted steel ball 13 and is separated the platform sealing washer 7 within a definite time detached distance size and adjust fluidic flow. After the inserting needle 11 is separated from the steel ball 13, the steel ball 13 blocks the separating platform sealing ring 7 again under the action of the spring 4, and fluid is blocked from flowing to the fluid outlet 9, so that the on-off control of the fluid is realized.
