" the on-line automatic sampler of crude oil " such as, Chinese patent application numbers 200820211504.8 discloses the on-line automatic sampler of a kind of crude oil.Its work structuring and principle are: sampling probe stretches in the crude oil pipeline, and connect manual ball valve successively by pipeline, filtrator, ebullator, mixer, knockout, flowmeter, manual ball valve, and end also stretches in the crude oil pipeline, and knockout connects sample receiver, control display and warning device." crude oil sampling machine " disclosed crude oil sampling machine of Chinese patent application numbers 200320107345.4 is a hydraulic means that is made of motor, oil pump, oil cylinder and hydraulic valve, motor is connected with oil pump power, one end of oil cylinder has back hydraulic fluid port, and the other end has preceding hydraulic fluid port, and there is oil return opening at the middle part.
These devices have used control devices such as ebullator, mixer, oil pump, oil cylinder, but also need external power supply, complex structure, operation inconvenience.And owing to made up multiple device, sealing property is relatively poor, causes light constituent material damage or volatile substances in the crude oil serious easily, thereby has influence on the true reflection of sampled oil product composition.
The utility model content
The technical matters that the utility model solves is: overcome the deficiencies in the prior art, a kind of piston type self-priming crude sampler of simple in structure, easy to operate, good airproof performance is provided.
Technical solution of the present utility model is: a kind of piston type self-priming crude sampler, comprise cylindrical shell, cover, the tube end, piston, push rod and valve, and cover, the tube end, are fixedly connected on the two ends up and down of cylindrical shell respectively, form static seal between the tube end and the cylindrical shell; Push rod passes the opening at cover center, and the promotion piston slides up and down along the longitudinal axis of cylindrical shell, and piston and cylinder inboard wall form slipper seal; At the bottom of described valve is connected tin, as the gateway of sampled oil product.
Described cylindrical shell, cover, the tube end and piston are selected the 316L stainless steel for use.
Static seal between the described tube end and the cylindrical shell, and the slipper seal of piston and cylinder inboard wall is packing seal.
Described gland sealed material is teflon or FFKM.
The opening part at cover center is installed sliding bearing, for moving up and down of push rod provides guide effect, and the friction when reducing pushrod movement.
Described valve is a two-way valve.
The support of described tube bottom fixed installation foot wheel.
Principle of work of the present utility model is: by piston type self-priming structure of the present utility model, when sampling, valve is connected on the oil pipeline, the former oil pressure that relies on pipe interior is with piston jack-up, and the crude oil self-priming enters cylindrical shell, valve-off after sampling is finished.When needing to take out sample,, utilize push rod to promote piston, sample is released valve opening.
The utility model beneficial effect compared with prior art is:
(1) the utility model is formed a piston type self-priming structure by cylindrical shell, cover, the tube end, piston, push rod and valve, can utilize to move on the internal pressure promotion piston in the crude oil pipeline and finish sampling, and do not need to use power drives such as pump, motor, simplify the structure handled easily.
(2) the utility model forms the slipper seal structure at piston and cylinder inboard wall by forming static seal at the bottom of the tube and between the cylindrical shell, can guarantee that sampler bears elevated pressures, and crude oil sample does not have leakage.And because structure member simple, good seal performance is difficult for causing light constituent material damage or volatile substances in the crude oil, thereby guarantees truly to reflect the composition of sampled oil product.
(3) employed stainless steel material of the utility model, and teflon or FFKM packing seal material, immiscible and sealing is reliable with the composition of crude oil, can not influence the composition of institute's sample thief.
(4) in addition, the utility model can adapt to moving and safe storage of multiple road conditions and surface condition at the support of tube bottom fixed installation foot wheel.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
As shown in Figure 1, 2, self-priming crude sampler of the present utility model comprises cylindrical shell 9, cover 8, the tube end 2, piston 3, push rod 4 and valve 1.Cylindrical shell 9, cover 8, the tube end 2 and piston 3 are formed the main body of sampler; Cover 8, the tube end 2, lay respectively at the two ends up and down of cylindrical shell 9; Valve 1 is the import and export of crude oil, by angle coupling 11 take over 10 be connected tin at the bottom of below 2.Valve 1 is a two-way valve in the present embodiment.
Form reliable packing seal structure by sealing gasket 14 between the tube end 2 and 9 times end flanges of cylindrical shell, as shown in Figure 3.In sampler inside or outside when pressure is arranged, can both effectively prevent the seepage of crude oil.
With cylindrical shell 9 contact positions fluting, installation forming O-ring seal 13 in the groove makes the motive seal that forms packing seal structure between piston 3 and the cylindrical shell 9 on the piston 3.The sealing means of this molded sealing ring makes between molded sealing ring 13 and the cylindrical shell 9 friction very little, also can be sucked into sampler when former oil pressure is very little, and piston 3 moves up and down freely.
The material of molded sealing ring 13 and sealing gasket 14 is teflon or FFKM, in the present embodiment, adopts teflon.
The opening that push rod 4 passes cover 8 centers promotes piston 3 and slides up and down along the longitudinal axis of cylindrical shell 9.In the present embodiment,, form the straight-line guidance effect between push rod 4 and the orienting sleeve 5, guarantee the rectilinearity when piston 3 moves up and down, make sealing more reliable at push rod 4 overcoat orienting sleeves 5.
Whole sampler main body can be by manually moving freely and transport by pull handle 6 by being installed in one movably on the support 12.
When the pipe laying on-site sampling, valve 1 wherein is connected with the sample tap of pipe laying, sampler is inner to form linker with pipe laying, the effect of the former oil pressure of piston 3 in-lines is risen down automatically, push rod 4 rises along the direction straight line of orienting sleeve 5, reach requirement up to sampling amount, valve-off 1.
The utility model makes that the pipeline on-site sampling time institute sample thief of crude oil is undistorted, the safety under the high pressure that can guarantee stainless steel can reduce the reaction with oil component again, hermetically-sealed construction can farthest reduce the loss of various ingredients reliably, and traversing carriage makes that transportation is convenient.
Certainly, under the situation that does not change its function, the equivalent transformation that carries out or alternative also falls into protection domain of the present utility model to each building block of the present utility model, position relation and connected mode.The undocumented technology of the utility model instructions belongs to techniques well known.
