Description
Technical field
This utility model relates generally to the check valve of well mouth of oil well, and the oil well carried out in parameter measurements such as linear flow rate, density, temperature, components uses to oilwell produced fluid amount to be particularly suitable for it is frequently necessary to arrangement, specifically a kind of from floating sealed well mouth of oil well check valve.
Background technology
Vertically arranged check valve is commonly used in current oil field, generally utilizes the gravity of flap or ball sealer, and downward seat, on seal receptacle, plays the effect preventing liquid from flowing backwards.
Current oil well check valve, can be only installed in the pipeline of the bottom-up flowing of liquid.If being arranged on the well head of oil well, the liquid meeting oil well output is needed from up to down to flow, and prevent liquid from upwards flowing backwards, traditional one-way valve structures is not appropriate for, if therefore using the check valve of traditional structure can only well mouth of oil well flow process be transformed, or in check valve body, runner is transformed, for instance increase by two U-shaped curved so that well mouth of oil well or one-way valve structures are complicated and workload is big；Furthermore the use of current check valve cannot realize at well head place to Liquid output in parameter measurements such as linear flow rate, density, temperature, components, if wanting, realizing measurement needs individually to improve oil well flow, and this will certainly increase workload and corresponding cost.
Utility model content
For solving the deficiency of current technology, this utility model is in conjunction with prior art, from practical application, there is provided a kind of from floating sealed well mouth of oil well check valve, this check valve has reliable operation, practicality, easily advantage, it is applicable to often carry out in parameter measurements such as linear flow rate, density, temperature, components to oilwell produced fluid amount, it is prevented that the well mouth of oil well that liquid flows backwards.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of from floating sealed well mouth of oil well check valve, including valve body, being provided with ball seat in described valve body, valve body is externally provided with inlet and outlet, is provided with baffle of porous baffle between described ball seat and outlet, relocatable ball sealer it is provided with between described baffle of porous baffle and ball seat, being additionally provided with first interface, the second interface on described valve body, described first interface communicates with import, and the second interface communicates with outlet, first interface is installed the first plug, the second interface is installed the second plug.
On described ball seat, the one end near import is provided with the 3rd plug.
Described ball seat bottom is provided with screw thread, and ball seat is tightened on valve body by screw thread, and ball seat top is conformed with.
Described valve body is angie type structure.
The beneficial effects of the utility model:
1, this utility model simple in construction, stable performance, long service life, liquid continuous backflow can be prevented when being applied in well mouth of oil well in time；And when oilwell produced fluid amount is carried out when parameter measurements such as linear flow rate, density, temperature, components by needs, the first plug, the second plug can be dismantled, 3rd plug is installed, the inlet line of oil well movable metering equipment is connected the first plug place, outlet line connects the second plug place, thus when the original flow process of well mouth of oil well not carried out variation transformation, it is achieved oilwell produced fluid amount, the various parameters such as moisture on-line metering admission.
2, the easy installation and removal of this utility model ball seat is quick, it is simple to operation and maintenance, and valve body adopts angie type structure negotiability big, and anti-blocking performance is good, and is applicable to the connection occasion of well mouth of oil well.

Accompanying drawing 1 is this utility model population structure schematic diagram.
Label shown in accompanying drawing: 1, import；2, valve body；3, outlet；4, the first plug；5, first interface；6, the 3rd plug；7, ball seat；8, ball sealer；9, baffle of porous baffle；10, the second interface；11, the second plug.
Detailed description of the invention
In conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be understood that these embodiments are merely to illustrate this utility model rather than limit scope of the present utility model.In addition, it is to be understood that after having read the content that this utility model is lectured, this utility model can be made various changes or modifications by those skilled in the art, and these equivalent form of values fall within the application appended claims limited range equally.
As shown in Figure 1, a kind of from floating sealed well mouth of oil well check valve, this check valve is angie type valve body, check valve includes valve body 2, ball seat 7 it is provided with in valve body 2, valve body 2 is externally provided with import 1 and outlet 3, it is provided with baffle of porous baffle 9 between ball seat 7 and outlet 3, relocatable ball sealer 8 it is provided with between baffle of porous baffle 9 and ball seat 7, being additionally provided with first interface the 5, second interface 10 on valve body 2, first interface 5 communicates with import 1, and the second interface 10 communicates with outlet 3, first interface 5 is installed the first plug 4, the second interface 10 is installed the second plug 11；On ball seat 7, the one end near import 1 is provided with the 3rd plug 6；Ball seat 7 bottom is provided with screw thread, and ball seat 7 is tightened on valve body 2 by screw thread, and ball seat 7 top is conformed with.
This utility model adopts angie type structure, it is vertically mounted on the top of well mouth of oil well back pressure valve, according to produced liquid in oil well body flow direction, on the top of valve body 2, import 1 is set, the bottom of valve body 2 arranges outlet 3, it is internal that ball seat 7 is threadedly secured to valve body 2, ball seat 7 is arranged between import 1 and outlet 3 and can make import 1 and outlet 3 through, the projection of ball seat 7 upper design specific purpose tool handling, the screw thread that internal setting matches with the 3rd plug 6, ball seat 7 bottom arranges ball sealer 8, ball sealer 8 is according to the low-density medicine ball of different choice unlike material or the hollow ball that use environment, ensure the ensemble average density density less than liquid of ball, baffle of porous baffle 9 is arranged on ball sealer 8 bottom and blocks ball sealer 8, hole on baffle of porous baffle 9 can make liquid pass through.Actually used method of the present utility model is as follows:
When properly functioning, 3rd plug 6 is not installed, it is internal that liquid import 1 from above flows into valve body 2, liquid backs down downwards ball sealer 8 by being flowed out by outlet 3 after baffle of porous baffle 9 by ball seat 7, when occurring that liquid refluxes, ball sealer 8 is due to the effect of natural buoyancy, it is possible to close the ball seat 7 of top in time, it is prevented that liquid continuous backflow.
When oilwell produced fluid amount is carried out at linear flow rate by needs, density, temperature, during the parameter measurements such as component, the first plug 4 can be dismantled, second plug 11 also installs the 3rd plug 6, the inlet line of oil well movable metering equipment is connected first interface 5 place, outlet line connects the second interface 10 place, now liquid is flowed into valve body 2 by import 1, enter through first interface 5 and entered outlet 3 outflow by the second interface 10 again after movable metering equipment, thus when the original flow process of well mouth of oil well not carried out variation transformation, realize oilwell produced fluid amount, the on-line metering admission of the various parameters such as moisture.
