Abstract
The utility model relates to an anti-splash ware used for a fossil oil chemical device, in particular to an oil pumping well portal, consisting of a housing 1, a connector 2, an end cover 3 and an anti-splash 7, a ball seat6, a spring 5, and a spring positioning bolt 4 inside the device. The anti-splash ware is designed properly, of simple structure; easy to be installed and employed, can operates reliably as well. Moreover, the utility model can be used to prevent the sudden splash, leakage accidents that occur during the operation of the fossil oil and chemical devices, and ensure safe production to avoid the loss of sources and environmental pollution. Therefore, the anti-splash ware is easy to be promoted and applied.
Description
Technical field:
The utility model relates to a kind of oil, the chemical industry equipment that is used to contain moving component, the particularly blowout hookup of pumpingh well well head.
Background technology:
In various oil, chemical industry equipment production run process, for example in the pumpingh well oil recovery process, the moving component that wherein contains (for example polished rod) is because long-term the use, about the work (or about) move back and forth, often because of mechanical wear or corrosion fracture suddenly.At present, because lack blowout hookup easy to use, reliable operation, the working media of device interior (as crude oil) is understood uncontrolled ejection or is leaked under this kind emergency case, not only causes the loss and waste of property resource, and serious environment pollution, threaten safety in production and personal safety.
Summary of the invention:
The purpose of this utility model be to provide a kind of petrochemical equipment in service can effectively prevent since wherein the moving component fault cause working media ejection, the preventer that leaks.
The utility model is to realize like this.This kind preventer is made up of housing, connector, end cap, spring, blowout prevention ball seat, blowout prevention ball and spring positioning bolt, and housing one face down bonding connects a tubulose connector, and the connector outer end is connected with end cap with screw thread; Spray-proof ball and blowout prevention ball seat are housed in the housing, and the ball seat outside is set with spring, and the spring outside is held out against the location with the spring positioning bolt that is screwed on the end cap.During use, this spray apparatus is looked actual conditions adopt bolt, screw thread or welding manner to be connected, and its inner chamber is sleeved on outside the moving component operation of can putting into production with relevant oil, chemical industry equipment.When moving component (for example pumpingh well polished rod) when rupturing suddenly, the spray-proof ball of its side promptly is pushed under the elastic force effect of spring and blowout prevention ball seat and is extruded onto the housing inner chamber, and the space that former cause breaking component is occupied replaces, thereby effective shutoff working media (for example crude oil) passage reaches and prevents the purpose that sprays, leak.
The utility model is reasonable in design, and is simple in structure, easy to install, reliable operation, the ejection of burst that utilizes it can effectively prevent oil, chemical industry equipment when particularly pumpingh well operation the is produced accident that leaks guarantees safety in production, avoid property resources loss and environment pollution, be suitable for and apply.
Description of drawings: accompanying drawing is a structural representation of the present utility model.
Number in the figure " 8 " is the moving component polished rod for example in oil, the chemical industry equipment.
The specific embodiment: enforcement of the present utility model is illustrated below in conjunction with accompanying drawing:
As shown in the figure: the utility model is made up of housing 1, connector 2, end cap 3, spring positioning bolt 4, spring 5, spray-proof ball 7 and ball seat 6, its structure assembled relation is as follows: a tubulose connector 2 is welded at housing 1 one side cross through hole places, and connector 2 outer ends are with the end cap 3 that has been threaded; Spray-proof ball 7 and blowout prevention ball seat 6 are housed in the housing 1, and spring 5 is equipped with in ball seat 6 outsides, and spring 5 outsides are held out against the location with the spring positioning bolt 4 that is screwed on the end cap 3.Wherein, housing 1 is a hollow circular cylinder, the one side has the cross through hole that preventer 7, ball seat 6 are set, and the moving component diameter in longitudinal hole internal diameter and its matches, and top, bottom surface are respectively equipped with and are attached thereto connection that relay part matches with bolt, screw thread or pad.
