Description
Technical field
The utility model belongs to oil-field flooding equipment part technical field, and regulating valve is blocked up in particularly a kind of antiscale.
Background technology
Regulating valve is widely used in the fluid pressurized of petroleum industry, induction system, applied to oil field constant-current water injection engineering
In water filling, note it is poly- when, regulating valve used is typically made up of valve body, valve rod, inner valve sleeve and outer valve sleeve, in inner valve sleeve and outer valve
Put and be respectively equipped with circular adjustment hole and fluid hole, shape between formation inner annulus, outer valve sleeve and valve body between inside and outside valve pocket
Into outer ring space, fluid enters inner valve sleeve by the import of valve body, the dislocation space of adjustment hole and valve rod by inner valve sleeve,
Enter into the inner annulus that buffering and stabilization are played to High Speed Turbulent, then by outer valve sleeve fluid hole after outer ring space
Reach valve outlet.Due in oil-field flooding note collecting process, injecting water quality inferiority and the chemical analysis containing easy fouling, causing note
Enter water to produce by wall circulation in inner annulus, adhere to fouling；And the fouling and clogging in the fluid hole by outer valve sleeve, influence
Degree of regulation, not only increases the expense and labor intensity of maintenance, and influence oil-field flooding efficiency.
The content of the invention
The purpose of this utility model be to provide one kind can effectively reduce fluid formed in valve body by wall circulation section and
Fluid hole attachment fouling, blocking, and the stifled regulating valve of the antiscale of degree of regulation can be improved.
Realize that the purpose of this utility model is adopted the technical scheme that：The regulating valve includes valve body and is sequentially arranged at valve
Gap between internal adjusting rod, interior adjusting set and outer adjusting set, inside and outside adjusting set forms annular water flow space, transfered to other localities
Gap between section set and valve body forms outer annular water flow space, wherein, provided with the footpath from top to bottom arranged in interior adjusting set
To adjustment hole, the circumferential location of outer adjusting set is laid with multiple discharge opeing through holes that the strip laid axially is arranged along it, should
Hole is connected by annular water flow space with the radiai adjustment hole in interior adjusting set, and the top circumference position of outer adjusting set is provided with upper
Seal groove, bottom is provided with the boss being connected with body cavity, and boss bottom face is provided with lower seal groove cavity, upper-lower seal groove
It is respectively provided with sealing ring.
The quantity in the radiai adjustment hole 7 is 5~8.
The quantity of the discharge opeing through hole is 3~6.
The cross section of the discharge opeing through hole is rectangular configuration, and the length in its hole is 45~50mm, and width is 2.5 ± 0.5mm.
The mm of the distance of the discharge opeing through hole and boss bottom face≤20.
Regulating valve is blocked up in the antiscale being made according to such scheme, and reasonable in design passes through the strip set in outer adjusting set
Shape discharge opeing through hole, make that its single hole area of passage is traditional circular hole area of passage 2.5 times, the gross area in 6 holes is the 1.8 of circular hole
Times, thus, it is possible to reduce fluid formation by wall circulation section, effectively prevent the hair of the attachment fouling of discharge opeing through hole and stopping state
It is raw, improve the degree of regulation of regulating valve and ensure water-injection efficiency, solve because the chemical analysis of water quality inferiority, easy fouling causes
The situation that the regulation valve pocket of regulating valve is blocked.The stifled regulating valve structure of the antiscale is reasonable in design, easy to operate, safe and reliable.
Brief description of the drawings
Fig. 1 is the utility model structural representation；
Fig. 2 is the structural representation of Fig. 1 China and foreign countries adjusting set.
Embodiment
Referring to Fig. 1, Fig. 2, regulating valve, including valve body 1 and the tune being sequentially arranged in valve body 1 are blocked up in antiscale of the present utility model
Gap between pole 2, interior adjusting set 3 and outer adjusting set 4, inside and outside adjusting set forms annular water flow space 6, outer adjusting set 4
Gap between valve body 1 forms outer annular water flow space 13, wherein, provided with the footpath from top to bottom arranged in interior adjusting set 3
To adjustment hole 7, the circumferential location of outer adjusting set 4 is laid with multiple strip discharge opeing through holes 5 for axially arranging and laying along it, should
Hole is connected by annular water flow space 6 with the radiai adjustment hole 7 in interior adjusting set 3, and the top circumference position of outer adjusting set 4 is set
There is upper seal groove 8, bottom is provided with the boss 9 being connected with the inner chamber of valve body 1, and the bottom face of boss 9 is provided with lower seal groove cavity 10, on
Sealing ring 11 and 12 is respectively provided with lower seal groove cavity.The quantity in the radiai adjustment hole 7 is 5~8, the quantity of discharge opeing through hole 5
For 3~6, the cross section of discharge opeing through hole 5 is rectangular configuration, and the length in its hole is 45~50mm, and width is 2.5 ± 0.5mm, row
The mm of the distance of fluid through-hole 5 and the bottom face of boss 9≤20.
In use, the valve body 1 for being arranged on regulating valve built with the outer adjusting set 4 of sealing ring 11,12 in upper-lower seal groove
On, the interior adjusting set 3 for installing adjusting rod 2 is arranged on fixation in outer adjusting set 4, rotation adjusting lever 2, regulation is lifted,
Inject water and enter interior adjusting set 3, by the radiai adjustment hole 7 and the dislocation space of adjusting rod 2 of interior adjusting set 3, into annular
Water flow space 6, valve outlet is reached after entering outer annular water flow space 13 by the discharge opeing through hole 5 of outer adjusting set 4.Due to discharge opeing
Through hole 5 is set to elongated rectangular shape structure, adds area of passage, shortens the empty effective length of inside and outside adjustment collar, therefore, reduces
By the formation of wall circulation section in valve, it is to avoid the attachment fouling of discharge opeing through hole and the generation of stopping state.
