Abstract
Combined type can safeguard that ball-and-seat is a kind of Novel single-stream valve gear, which overcomes the shortcoming of original ball-and-seat, and it is formed by connecting by upper cavity, lower chamber, sieve plate, valve ball, plug, valve seat, spring collar, O type rubber ring, box cupling; Valve body is formed by connecting by upper cavity, lower chamber two large divisions, and the upper end of lower chamber is fixed in the lower end of upper cavity; In the side of upper cavity, box cupling is installed; Valve inner is through-hole structure, and in valve body, valve seat is connected with lower chamber, and there is the seal with elastometic washer of O type centre, and its top is fixed by spring collar; Valve ball is positioned at valve seat upper sieve plate and is fixed on upper cavity top, sieve plate has several through holes; Plug is connected with box cupling by screw thread; The junction of plug and box cupling has sealing mat to seal.
Description
Technical field: the utility model relates to a kind of Novel single-stream valve gear, and especially combined type can safeguard ball-and-seat.
Background technology: current known oilfield oil well ball-and-seat and pipeline are by being welded to connect, and complex structure is not maintainable; The liquid of oil filed pipeline circulation is high salinity profit, and corrosion strength is strong, and ball-and-seat is perishable, and the life-span is short, frequently changes; Replacement operation is complicated, wastes a large amount of manpower and materials.
Summary of the invention: it is simple that the object of this life utility model is to provide structure, combined type easy to maintenance can safeguard ball-and-seat, which overcome the shortcoming of original ball-and-seat, the purpose of this utility model is achieved in that the utility model is formed by connecting by upper cavity, lower chamber, sieve plate, valve ball, plug, valve seat, spring collar, O type rubber ring, box cupling; Valve body is formed by connecting by upper cavity, lower chamber two large divisions, and the upper end of lower chamber is fixed in the lower end of upper cavity; In the side of upper cavity, box cupling is installed.
Described valve inner is through-hole structure, and in valve body, valve seat is connected with lower chamber, and there is the seal with elastometic washer of O type centre, and its top is fixed by spring collar; Valve ball is positioned on valve seat.
Described sieve plate is fixed on upper cavity top, sieve plate has several through holes.
Described plug is connected with box cupling by screw thread; The junction of plug and box cupling has sealing mat to seal.
Application process of the present utility model is that liquid enters individual event valve from body base, and liquid-driving valve ball moves upward, and liquid can smooth flow, and when stop liquid feed flow, valve ball falls with gravity until on valve seat, can prevent liquid from flowing backwards.Valve body side is provided with plug, so just ball-and-seat need not be cut down from pipeline and carry out having keeped in repair, as long as screwed down from box cupling by plug, then overhaul ball-and-seat, changes valve ball or ball seat.Valve ball directly can take out, and takes out spring collar just can take out valve seat with spring collar pincers.Again plug is screwed on after having keeped in repair, just complete the maintenance work of ball-and-seat.Box cupling and plug adopt gas thread to be connected, and the junction of box cupling and plug does not have profit and leaks out, and ball seat uses guarantees production safety.
Meaning of the present utility model is: the utility model structure is simple, easy to use, can directly overhaul on working position, changes consumable accessory, substantially prolongs the life-span of ball-and-seat, saved manpower and materials, improve the production efficiency of oil-water well.
Accompanying drawing illustrates: Fig. 1 is the structural representation that combined type can safeguard ball-and-seat: in figure 1, upper cavity 2, lower chamber 3, sieve plate 4, valve ball 5, plug 6, valve seat 7, spring collar 8, O type rubber ring 9, box cupling
Detailed description of the invention: embodiment 1, the utility model are formed by connecting by upper cavity 1, lower chamber 2, sieve plate 3, valve ball 4, plug 5, valve seat 6, spring collar 7, O type rubber ring 8, box cupling 9; Valve body is formed by connecting by upper cavity 1, lower chamber 2 two large divisions, and the upper end of lower chamber 2 is fixed in the lower end of upper cavity 1; In the side of upper cavity 1, box cupling 9 is installed.
Embodiment 2, described valve inner are through-hole structure, and in valve body, valve seat 6 is connected with lower chamber 2, and centre has O type rubber ring 8 to seal, and its top is fixed by spring collar 7; Valve ball 4 is positioned on valve seat 6.
Embodiment 3, described sieve plate 3 are fixed on upper cavity 1 top, sieve plate 3 have several through holes.
Embodiment 4, described plug 5 are connected with box cupling 9 by screw thread; Plug 5 has sealing mat to seal with the junction of box cupling 9.
Embodiment 5, application process of the present utility model are that liquid enters individual event valve from body base, and liquid-driving valve ball moves upward, and liquid can smooth flow, and when stop liquid feed flow, valve ball falls with gravity until on valve seat, can prevent liquid from flowing backwards.Valve body side is provided with plug, so just ball-and-seat need not be cut down from pipeline and carry out having keeped in repair, as long as screwed down from box cupling by plug, then overhaul ball-and-seat, changes valve ball or ball seat.Valve ball directly can take out, and takes out spring collar just can take out valve seat with spring collar pincers.Again plug is screwed on after having keeped in repair and just complete the maintenance work of ball-and-seat.Box cupling and plug adopt gas thread to be connected, and make the junction of box cupling and plug not have profit and leak out, and ball seat uses guarantees production safety.In sum, the utility model structure is simple, easy to use, directly can carry out examine and replace consumable accessory on working position, substantially prolongs the life-span of ball-and-seat, save manpower.
