Structure chart when Fig. 2 is the utility model oil well sampling detection valve open;
Fig. 3 is the structure chart that the another kind of oil well sampling of the utility model detects valve.
The specific embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
See figures.1.and.2, the sampling of oil well that the utility model provides detects valve, comprises being used for the valve body 2 that is connected with petroleum pipeline 1 and built-in spool 3 and being used for the travel mechanism of spool 3 in valve body 2 relative motions by what the nut 6 of valve gap 5, valve stifled 7 and controlled valve was formed.
Wherein, spool and valve body cooperate, spool 3 is a cylinder, the end is provided with the needle 8 that fuses with it by conical surface transition, when needle 8 stretches out from the inlet of valve body 2, needle 8 has the section of stretching out, and in other embodiment of the utility model diaphragm valve, needle 8 also can be made cone or the cylinder that the cross section is an Any shape.Spool 3 cooperates by the valve base sealing of the conical surface with valve body 2, is conical surface transition owing to what adopt between the seal section, so guarantee not leak when pressure measurement.Spool 3 is provided with sealing ring 4, and spool and valve body seal with sealing ring 4.
Nut 6 is sleeved in the valve gap 5 and by screw thread and matches with valve body 2, can be used for controlled valve.The leading section of nut 6 is provided with and is used for spacing boss 9, and valve gap 5 is fixed by welding on the valve body 2, when preventing that nut 6 from opening, owing to control comes off bad causing, thereby guarantees to take a sample and the safety of pressure measurement.In other embodiment of the utility model diaphragm valve, valve gap 5 and the connected mode of valve body 2 also can adopt the connected mode of screw thread.
Valve stifled 7 places the rear portion of spool 3 and is welded to each other together with nut 6, guarantees that spool can not become flexible when valve-off, also plays antitheft effect.In other embodiment of the utility model diaphragm valve, valve stifled 7 and nut 6 also can adopt the connected mode of screw thread as required.On the valve stifled 7 handle 12 is installed.
The another kind of oil well sampling of the utility model detects valve, with reference to Fig. 3, comprises being used for the valve body 2 that is connected with petroleum pipeline 1 and built-in spool 3 and by the travel mechanism that comprises that valve gap 5 constitutes.Wherein, spool and valve body cooperate, and spool 3 is identical with top embodiment with the structure that sampling detects hole 10.Valve body 2 is connected with spool 3 by screw thread at afterbody one end, and spool 3 is sleeved in the valve gap 5 and is provided with and is used for spacing boss 11, and valve gap 5 is fixed on the valve body 2.Handle 12 is installed on the spool 3.
The utility model diaphragm valve in use, valve body 2 is welded direct on the petroleum pipeline 1, to play antitheft effect.It is stifled to take off the sealing of adorning fully in sampling detection hole 10 simultaneously, if detect, then the gaging pressure table is installed on the detection hole 10 of taking a sample.
Result of use below in conjunction with description of drawings the utility model diaphragm valve.
The oil well sampling that the utility model provides detects valve, when valve body and petroleum pipeline welding, valve body can be deep in the inwall of petroleum pipeline, spool is behind valve closing, the head of spool stretches out outside the valve body, that is to say that the spool head enters into the inside of petroleum pipeline, make it, reduce frozen possibility in cold winter.
In use, with reference to Fig. 1, when the needs valve-off, the right rotation nut, the endoporus of the conical surface of spool and valve body is cooperated after, just can close and seal; With reference to Fig. 2, when needs pressure measurement or sampling, as long as the anticlockwise nut, after nut is used for spacing boss and the end cap portions of valve gap contacts, needle will withdraw from the hole, makes to form one in the valve body by the passage in sampling detection hole that enters the mouth, thereby can reach the purpose of sampling and pressure measurement.
Because spool is the steel body, so,, finish the work of pressure measurement and sampling as long as powerful swivel nut will be opened passage even valve body and spool freeze.Even like this in cold winter, as long as feed-line is not frozen, just can not freeze, it is simple in structure, safe and reliable, and easy to use and easy maintenance is for the sampling testing in cold winter provides the equipment that is suitable for.
