Abstract
A kind of porous leakproof spool is mainly used in the closed circuit sampler that petrochemical field examines finished product oil quality.And this closer often makes the thief-sampler diaphragm of inspection oil quality fall in the recycling oil pipeline of closed circuit sampler when staff operates with, and pipeline blockage is caused to influence normal work.The main points for solving the problems, such as this are exactly to stop that thief-sampler diaphragm enters recycling oil pipeline, without influencing normal Oil Recovery.So the key point of this novel porous leakproof spool is that the diameter of through-hole is less than thief-sampler particle minimum diameter at any angle.This utility model is mainly used for the closed circuit sampler ball valve core on aircraft bowser.
Description
Technical field
The utility model is related to spool technologies, specifically design a kind of Leakproof ball valve valve for preventing particulate matter from falling into pipeline
Core.
Background technology
At present, petrochemical field at home, in order to detect the appearance oil quality of clean petroleum product by visual observation, in pipeline
On be designed with closed circuit sampler.And the spool of original closed circuit sampler bottom fuel outlet valve is a circular through-hole.It is this to close
Road sampler is also widely installed in the outlet of filter separator.When staff is surveyed using needle tubing and special chemical thief-sampler
Whether formation testing product in the operating process containing moisture, be sleeved on the chemical water test device diaphragm on needle tubing head it is possible that come off fall into it is closed circuit
In sampler, and detected oil product is followed to be flowed by ball valve in the pipeline of recycling oil product, cause the pipe of recycling oil product
Lu Buchang is even blocked, and then is influenced the closed circuit sampler and worked in systems.And drawing the change that takes down into pipeline with tool
During thief-sampler diaphragm, it is possible to damage the screw thread on screw thread or nut on closed circuit sampler bottom connector rails.If
Damage the screw thread on bottom linkage rod, then entire closed circuit sampler just needs replacing, so causing the economic loss of bigger.
Invention content
The problems in pipeline is fallen into order to thoroughly eradicate chemical water test device diaphragm.The present invention provides a kind of porous anti-drip valve
Core can not only stop that chemical water test device diaphragm is fallen into pipeline, and can guarantee that oil product is normally flowed into recycling fuel tank.
Technical solution
The present invention is that a circular through hole spool of original closed circuit sampler is transformed into the valve of multiple small through-holes
Core, the diameter that metapore is transformed are less than chemical water test device diaphragm minimum diameter at any angle.Make it that can be blocked after falling
In sampler, it will not be flowed into recovery pipe and that results in blockage with light-end products
The utility model has safety, simply, the features such as being applicable in, there is popularization and practical value well.It is extensive to promote
The drawbacks of good using effect can be generated after, has prevented chemical water test device diaphragm blocking pipeline completely.
Description of the drawings：Fig. 1 is the three-view diagram of Novel valve core
Fig. 2 is the A-A sectional views of Novel valve core
Fig. 3 is the installation effect figure of Novel valve core
Specific embodiment
The present inventor presses embodiment：One section of suitable stainless steel bars is taken, becomes solid ball valve core by mechanical processing.This
Spool up and down two circular flats to spool transverse center section distance for 13mm, upper and lower two circular flats it is a diameter of
22mm, then centered on the longitudinal axis center of spool, one a diameter of 6mm of brill among two circular flats of a diameter of 22mm
Upper lower through-hole.Four a diameter of 4 millimeters of through-holes are uniformly bored in this diameter of 6 millimeters through-hole surrounding.Then in spool
Outer surface centered on horizontal median axis, is parallel to two planes up and down, it is that 6mm depth is that open a length, which be 16mm width,
The U-lag of 3mm, for installing the Handle axis of control spool open and close position.
Claims (2)
1. a kind of porous leakproof spool is applied in the closed circuit sampler of detection clean petroleum product presentation quality, it is characterized in that：Valve
In the on state, there are five perforative through-hole, a diameter of 6mm of interstitial hole, the diameters in four holes of surrounding for upper and lower surfaces for core
For 4mm.
2. porous leakproof spool according to claim 1, it is characterized in that：The shape of through-hole is round, ellipse, triangle
Shape, square, rectangle, sector, diamond shape, pentagon, hexagon or tiny one or more of netted.
