Abstract
The utility model discloses a disassembly-free flow controller for filtration for mainly solving the problems that the existing flow control device is easy to be blocked and eroded, has small flow area, wastes time and energy to mount and dismount a water nozzle and cannot guard against theft. A water nozzle assembly is fixed to a central position of a three-way shell by a connecting screwed plug 2 with screw threads. The water nozzle assembly comprises an upper anti-theft bolt 1, a front water inlet 6 of the water nozzle, a filter screen 4(the aperture is smaller than 0.8 mm), a water nozzle 8, a fixing pedestal 7, a water outlet sealing pedestal 9 and the like.
Description
Technical field
The utility model relates to a kind of fluid flow control device in the oil recovery field, oil field, especially exempts to tear open the type flow control valve for oil well provides the filtration of quantitative water mixing and dosing.
Background technology
In the oil recovery process of oil field, add chemical agent for realizing quantitative water mixing of oil well surface line or downhole oil cover annular space, and add dose to watering quantity and control.Conventional gate valve and needle valve can't be the stable 0.1m that is controlled at of the water yield (dose)
3/ h-0.2m
3In the scope of/h, therefore adopt minor diameter water nozzle (0.8mm-1.6mm) to control flow usually.Because the water nozzle diameter is very little, the foreign material in the fluid media (medium) stop up water nozzle with oily with fixed attention through regular meeting.Existing flow control valve uses the screen casing impurity screening of aperture greater than 1.2mm, and filter effect is relatively poor.And, have a strong impact on the down-hole and add dose because the screen casing area of passage causes main body control part pressure reduction to diminish for a short time.On the other hand, when oil well needed big flow water mixing well-flushing and flushing surface line, common flow control valve must be removed control section, has caused the inconvenience of production management, and has increased workman's working strength.In addition, because the common discharge controller does not possess anti-theft feature, non-specialized-technical personnel can arbitrarily control this device, cause mismanagement.
The utility model content
Be prone to stop up in order to overcome existing flow control device, perishable, area of passage is little, the installing/dismounting water nozzle is wasted time and energy and non-anti-theft deficiency; But the utility model provides impurity in a kind of filtered fluid medium, and exempts from the novel flow control valve that the dismounting water nozzle is realized big flow clean-up line.This flow control valve have filtering function strong, exempt from dismounting, antitheft, characteristics easy to use.
The technical scheme that the utility model adopts is: a kind of filtration exempts to tear open the type flow control valve, comprises threeway shell 3, and seal and water nozzle assembly constitute; Threeway shell 3 comprises water inlet 5, delivery port 10 and is used for fixing the connector that is connected plug 2 three parts of water nozzle assembly; The water nozzle assembly is fixed on threeway shell centre through connecting plug 2; The water nozzle assembly by top anti-theft bolt 1, water nozzle before water inlet 6, screen pack 4, water nozzle 8 and firm banking 7, delivery port sealed base 9 form.
As further improvement, said described screen pack aperture is less than 0.8mm.
Described seal is " O " RunddichtringO.
Described water nozzle assembly have filtration, on carry, seat envelope function.
The utlity model has following beneficial effect:, avoided fully because the interior impurity of fluid stops up the control water nozzle owing to adopt such scheme.And, effectively improved the dosing effect because the increase of area of passage has increased down-hole dosing pressure reduction.When oil pipeline needs big flow liquid to pass through, can use water lift mouth assembly on the special-purpose Anti-theft wrench, water nozzle base and delivery port base hermetic unit are broken away from, open normal big traffic channel, reach and do not remove the purpose that water nozzle is realized big flow clean-up line.In addition, owing to adopt the anti-theft type special spanner, avoided the layman arbitrarily to change the set water yield.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The 1-anti-theft bolt, 2-connects plug, 3-threeway shell,
The 4-screen pack, water inlet before the 5-water inlet, 6-water nozzle,
The 7-firm banking, the 8-water nozzle, 9-delivery port sealed base,
The 10-delivery port.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
In conjunction with shown in Figure 1, filter and to exempt to tear open the threeway shell 3 that the type flow control valve comprises metal material, seal and inner have filtrations, on carry, the water nozzle assembly formation of seat envelope function.Threeway shell 3 comprises water inlet 5, delivery port 10 and is used for fixing the connector that is connected plug 2 three parts of water nozzle assembly.The water nozzle assembly is fixed on threeway shell centre through threaded connection plug 2.The water nozzle assembly by top anti-theft bolt 1, water nozzle before water inlet 6, screen pack 4 partly form less than 0.8mm, water nozzle 8 and firm banking 7, delivery port sealed base 9 etc. in the aperture of screen pack in the present embodiment; Seal is " O " RunddichtringO.In the present embodiment, the sealing sealing ring is the rubber material.
During operate as normal, firm banking 7 and 9 sealings of delivery port sealed base, water inlet 5 come liquid through the screen pack of aperture less than 0.8mm after, after damming through water nozzle 8 through water inlet 6 before the water nozzle, flow out with both constant flows.When needing big flow well-flushing; Need not stop water mixing dismounting control assembly,, firm banking 7 separated with delivery port sealed base 9 through water lift mouth assembly on the special spanner rotation anti-theft bolt 1; Open big traffic channel, the impurity that inside cavity is piled up is walked in flushing simultaneously.The workman is easy and simple to handle, does not influence the oil well ordinary production.
What should explain at last is: above embodiment is the described technical scheme of unrestricted the utility model in order to explanation the utility model only; Therefore, although this manual has carried out detailed explanation to the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of novel spirit and scope, and it all should be encompassed in the middle of the claim scope of the utility model.
