Abstract
The utility model provides an air control valve, which belongs to the valve of an oil field production device. The air control valve comprises a cylindrical valve body, the front part of the valve body is provided with a front chamber hole, the rear part of the valve body is provided with a rear chamber hole which is communicated with the front chamber hole, the aperture of the rear chamber hole is smaller than the aperture of the front chamber hole, the front end of the front chamber hole is provided with a valve seat, a conical head on the front end of a valve stem arranged in the front chamber hole is sleeved in a central hole of the valve seat, and a spring is arranged outside the valve stem and between the conical head and the rear end face of the front chamber hole. When in use, the air control valve can be connected with the air bleeding pipelines of the oil well casing or the single-well oil storage tank, when certain air pressure is formed, the air control valve can automatically open to discharge air, and when the air pressure is lowered to a certain degree, the air control valve can automatically close, thereby adapting to oil field production requirements. The utility model has the advantages of simple and reasonable structure, low manufacturing cost and good using effect.
Description
Technical field
The utility model provides a kind of valve, the valve on especially a kind of field produces device.
Background technique
At present, the sleeve pipe gas (main component is a rock gas) that the oil field is produced in recovering the oil and producing directly bleeds off, and this not only can cause waste, also can make the cover intraductal atmospheric pressure low excessively, influences oil well output.In addition, when the individual well oil storage tank being heated with discharge crude oil, the gas that had both needed to produce in the jar is discharged, and makes jar certain pressure of interior maintenance again, and present also do not have suitable device to realize this function.
Summary of the invention
The utility model wants the technical solution problem to be, a kind of air control valve is provided, and it can be opened under certain gas pressure automatically.
The utility model is to realize like this, a kind of air control valve, it has the valve body of tubular, the valve body front portion have preceding lumen pore, rear portion to have to communicate with preceding lumen pore and the aperture less than the back lumen pore of preceding lumen pore, front end at preceding lumen pore is equipped with valve seat, before the conical head of the valve rod front end installed in the lumen pore be sleeved in the center hole on the valve seat, the outside of valve rod has spring to be installed between conical head and the preceding lumen pore ear end face.
Adopt the air control valve of said structure, during use, can be connected on well casing gas atmospheric pipe or the individual well oil storage tank, when gas reaches certain pressure, automatically open, gas is discharged, after gas pressure is reduced to a certain degree, can close automatically again, adapted to the field produces requirement, and simple and reasonable, low cost of manufacture, using effect is good.
Description of drawings
Fig. 1 is the schematic representation of the utility model structure.
Fig. 2 is the left view of Fig. 1.
Embodiment
The embodiment who provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model.
As shown in drawings, a kind of air control valve of the utility model, it has the valve body 4 of tubular, there is preceding lumen pore 2 the valve body front portion, the rear portion has with preceding lumen pore communicate and the aperture less than the back lumen pore 6 of preceding lumen pore, front end at preceding lumen pore is equipped with valve seat 1, before the conical head 7 of valve rod 3 front ends installed in the lumen pore be sleeved in the center hole on the valve seat, the outside of valve rod has spring 5 to be installed between conical head and the preceding lumen pore ear end face.
Valve seat is installed in the front end of the preceding lumen pore of valve body by screw thread.
During use, can link together by the outside thread of valve body front end and the outlet pipe on well casing gas atmospheric pipe or the individual well oil storage tank.In the using process, when gas reaches certain pressure, in the time of can overcoming the elastic force of spring, the conical head of valve rod front end and the center hole on the valve seat break away from, and this valve is opened automatically, and gas is discharged by preceding lumen pore, back lumen pore.After gas pressure was reduced to and to a certain degree promptly is lower than spring force, the conical head on the valve rod blocked the center hole on the valve seat again under the effect of spring, and this valve cuts out automatically.In the production, can gas be guided on the gas equipment being connected the valve body rear portion with the tracheae line.
