Description
Technical field
The utility model relates to a kind of sampler, relates in particular to a kind of liquid sampling valve that ducted liquid is taken a sample of being used for.
Background technology
Liquid in the industry delivery line such as oil, chemical industry, tap water need be sampled chemical examination usually to determine its physicochemical characteristics, so that take appropriate measures, when in petroleum transportation pipeline, carrying such as oil, must on the pipeline every certain distance to the detection of taking a sample of the oil in the pipeline.Its structure of known sample valve is similar to ordinary faucet, because its installation, easy to operate and be widely applied in the industry-by-industry list, yet because this kind sample valve mostly is ironcasting, easily produce corrosion, what is more important, after sampling is finished, spool is closed, more residual liquid of meeting in the sample valve, therefore in sampling for the second time, usually need carry out emptying earlier and handle, with regard to the oil sample valve, each emptying needs 0.3Kg approximately, all petroleum transportation pipeline list sampling emptying so over a year just need waste to go up the oil of kiloton, and this oil will pollute its peripheral environment, be becoming tight in energy day, the age of environmental protection is called by society, is necessary to develop a kind of liquid sampling valve that need not emptying.
Summary of the invention
The utility model provides a kind of simple in structure, liquid sampling valve of need not emptying.
The technical solution adopted in the utility model is such: a kind of liquid sampling valve, comprise valve rod, valve body, cooperate the spool that is used to open or turn-off valve body feed pathway and liquid outlet channel with described valve body, described spool is fixedly arranged on the vertical end of valve rod, the valve rod other end extends to the outside of valve body and which is provided with operating grip, be provided with packoff between described valve rod and the valve body, described valve rod middle part is provided with boss, described boss lateral surface is provided with thread, on the described valve body position that should boss is provided with and the suitable screw thread of described thread, that side that described spool and valve rod are adjacent is provided with sealing cone, and described valve body feed pathway is provided with and the suitable valve seat of the described conical surface.
The aforesaid liquid sample valve, described valve rod and spool are integrally formed.
The aforesaid liquid sample valve, the parallel axes at described feed pathway and the vertical place of valve rod.
The aforesaid liquid sample valve, described liquid outlet channel is axial vertical with the vertical place of valve rod.
Preferred aforesaid liquid sample valve, described valve body are provided with fixedlys connected the internal thread of usefulness with liquid-transport pipe-line.
The utility model is by being provided with thread on the outside portion of valve rod middle part boss, and the valve body corresponding position is provided with screw thread, cooperate with thread by screw thread, described valve rod can move with respect to the longitudinal direction of valve body along valve rod, opens or closes feed pathway thereby drive the spool that is anchored on its end, and the liquid of feed pathway constantly is replaced owing to the flow-disturbing effect like this, the then natural overflow of liquid on the liquid outlet channel, therefore residual few, following sub-sampling is accurate, need not emptying.

Embodiment
With reference to figure 1, Fig. 2, Fig. 3, embodiment provides a kind of oil sample valve, this sample valve is located at the oil that is used in the petroleum transportation pipeline carrying and is carried out sample analysis, this oil sample valve comprises valve rod 1, valve body 2, spool 3, wherein, described valve rod 1 one ends are positioned at valve body 2, the other end is positioned at outside the valve body 2, it is integrally formed that valve rod 1 is positioned at an end and the spool 3 of valve body 2, described spool 3 and valve rod 1 coupling part, its periphery is a conical surface that seals 31, described valve rod 1 is positioned at valve body 2 outer ends and is provided with square toes, one turning handle is sheathed on can drive this valve rod 1 rotation on these square toes, this turning handle and valve rod 1 can also be the rotary handles on the known water swivel, the middle part of described valve rod 1 is provided with boss 11, and described boss 11 is external diameter cylinder boss greater than valve rod 1 other parts, and described boss 11 sides are provided with thread.
With reference to figure 1, described valve body 2 have along valve rod 1 length direction vertically, be provided with through hole in the middle of valve body 2 longitudinal directions, described through hole one end is a feed pathway 21, the described through hole other end cooperates with valve rod 1, and this mating part is provided with packoff, described packoff is one and revolves the pressure cap of being located on the valve body 24, be provided with sealing gasket 41 between described pressure cap 4 lower surfaces and valve body 2 upper surfaces, be provided with O-ring seal 42 between described valve body 2 and the valve rod 1, the position of the corresponding aforementioned boss 11 in described valve body 2 through holes middle part is provided with and the suitable screw thread of described thread, the side of valve body 2 is provided with the liquid outlet channel 22 vertical with described feed pathway 21, and described feed pathway 21 has a valve seat 23 with spool 3 mating parts, described valve seat 23 is that a girth is less than the step on the described through hole of being located at of described feed pathway 21, cooperate with the aforementioned conical surface 31 by valve seat 23, feed pathway 21 realizes by rotary valve rod 1 with the open and close of liquid outlet channel 22, described in addition valve body 2 is provided with fixedlys connected the internal thread of usefulness with liquid-transport pipe-line, by this internal thread, described oil sample valve can be fixed on the oil pipeline easily.
Design philosophy of the present utility model is valve body feed pathway and valve rod vertical consistency, by on the outside portion of valve rod middle part boss, thread being set, and the valve body corresponding position is provided with screw thread, cooperate with thread by screw thread, described valve rod can move with respect to the longitudinal direction of valve body along valve rod, opens or closes feed pathway and takes a sample thereby drive the spool be anchored on its end, thereby farthest reduce residual after each sampling, sub-sampling is put residual step, promptly energy-conservation environmental protection again under removing from.
