The utility model provides a ring type flow process wellhead combined valve. A valve unit (1) is provided with a single-flow valve (2), a stop valve (6), a pressure test needle valve (7) and a needle sample valve (8) inside; inside of the valve unit (1) has an oil inlet (13) which is communicated with a single-flow valve hole (9), the single-flow valve hole (9) is communicated with a stop valve hole (11) via a through hole (10), an oil outlet (12) is arranged downward at the bottom wall of the stop valve hole (11) and is opposite to the oil inlet on the same axes, a pressure test needle valve hole (14) and a needle sample valve hole (16) are arranged at the two levelly symmetrical sides of a oil inlet (13) and are opposite to each other and is communicated with the oil inlet (13). A pressure meter hole (15) is arranged upward on the bottom wall of the pressure test needle valve hole (14), a sample hole (17) is arranged downward on the bottom wall of a needle sample valve hole (16) and each valve is provided with a protection cover (24). The utility model is a substitute to an oil exploitation wellhead valves set.
Description
Technical field:
The utility model relates to a kind of ring-type flow process well head combination valve that recovers the oil in the oil field that is used for
Background technology:
At present oil field oil recovery ring-type flow process well-head valve group comprises oil recovery, pressure measurement, sampling etc., adopts pipeline to connect between valve, is a kind of combining form in bulk, and floor space is big, the process Installation amount is big, and corrosion-resistant thermal insulation difficulty, maintenance management inconvenience, theftproof performance are poor.
The utility model content:
In order to overcome the existing big deficiency of well-head valve group floor space, the utility model provides a kind of ring-type flow process well head combination valve, and this combination valve volume is little, the batch production assembling, but centralized operation is convenient to corrosion-resistant thermal insulation, is beneficial to maintenance management, safe antitheft.
The technical scheme that the utility model adopted is: the ring-type flow process well head combination valve that well head valve in bulk is combined into one, include ball-and-seat, stop valve, pressure measurement needle valve, sampling needle valve, it is characterized in that: four kinds of valves are assembled in the valve body, be communicated with through hole between each valve, valve body has oil-in, single current valve opening, intercommunicating pore, ends valve opening, oil-out, and above-mentioned each hole top view projection is all on same axis; 90 ° of last foldings communicated with the single current valve opening after oil-in fed valve body, ball-and-seat aperture intercommunicating pore with communicate by valve opening, have the oil-out reverse by valve opening downwards near the bottom hole wall with the oil-in coaxial line, have pressure measurement aciculiform valve opening, sampling aciculiform valve opening in the horizontal symmetrical both sides of oil inlet pipe, all communicate with oil-in, have upwards 90 ° of pressure meter holes that fold the valve body outside at pressure measurement aciculiform valve opening near the bottom hole wall, open a thief hole at sampling aciculiform valve opening downwards near the bottom hole wall, lead to the valve body outside; Protector all is equipped with in each valve outside.
Above-mentioned protector has the screw hole that step is arranged in a plurality of, the pin hole of step and the round metal annular protection seat in interior spiral shell literary composition hole are arranged in two, penetrate pin in the pin hole, put into stage clip, anti-guard housing is connected with valve body, on the anti-guard housing symmetry is installed and is drilled with the cavity protection cover that two pin jacks, upper ends have a valve opening hole, circular outer wing is arranged.
The utility model beneficial effect compared with prior art is: with this ring-type flow process well head combination valve, can replace former valve group in bulk, have that volume is little, in light weight, factory's combine and assemble, reduce the assembled on site workload, and can reduce the stolen phenomenon and take place.
