Abstract
The utility model provides a ground check valve of a pumping well, which is equipment for oilfield pumping wells. The ground check valve comprises an upper flange, a valve ball, valve seat, a valve body, a valve seat joint, a lower flange and a baffle, wherein the valve seat is mounted in the valve body; the valve ball sits on the valve seat; an upper thread of the valve seat joint is connected with a lower thread of the valve body; the upper end surface of the valve seat joint presses the lower end surface of the valve seat; the upper part of the valve body is inserted into an inner hole of the upper flange; the upper part of the valve body is welded with the upper flange; the lower part of the valve seat joint is inserted into the inner hole of the lower flange; the lower part of the valve seat joint is welded with the lower flange; the baffle is fixed at the upper part of the valve body; when the valve ball sits on the valve seat, a distance of 5-50 mm is available between the baffle and the valve ball; as the upper end and the lower end of the baffle are arranged as flanges, the baffle is convenient to be connected with a field pipeline; overhauling and replacing operations can be finished by a common worker without electric welding; and during overhauling, the advantages of short oil well idling period, small effect on oil well yield and obvious economic benefits are obtained.
Description
Technical field
The utility model is the equipment that oil field pumping well is used, and is a kind of pumpingh well ground ball-and-seat.
Background technology
In oil field pumping well, when oil well stopped well for some reason, in the interior extraction liquid of oil pipe can flow backwards Hui Jing on the oil well pump, when the pipeline rupture on the oil well pump was missed, the extraction liquid in the oil pipe on the oil well pump also can flow backwards in the Hui Jing.Extraction liquid flows backwards, and causes production loss on the one hand, also can cause the ground damage layer on the other hand, therefore; Need be at pumpingh well floor mounted ball-and-seat, the ball-and-seat that uses at present need be welded on the flow line, and complicacy is installed, and workload is big; Set-up time is long, and therefore, maintenance is inconvenient; During maintenance the oil well off-time long, influence oil well production, produce economic loss.
Summary of the invention
The purpose of the utility model is a kind of pumpingh well of design ground ball-and-seat, adopts flange to connect, and it is convenient to install and overhaul.
The purpose of the utility model is achieved in that and comprises upper flange, valve ball, valve seat, valve body, valve base joint, lower flange, baffle plate, and valve seat is installed in the valve body, and the valve ball seat is on valve seat; Valve base joint top screw thread is connected with the valve body lower portion spiral shell, and the valve seat lower surface is pushed down in the valve base joint upper surface, and insert in the upper flange endoporus on valve body top; Valve body top and upper flange welding; Insert in the lower flange endoporus valve base joint bottom, valve base joint bottom and lower flange welding, and baffle plate is fixed on valve body top; The valve ball seat has the 5-50mm distance on valve seat the time between baffle plate and the valve ball.
The beneficial effect of the utility model is: two ends are set to flange up and down, are convenient to be connected with on-the-spot pipeline, and maintenance does not need electrogas welding when changing; The common laborer just can operate completion; Oil well off-time weak point during maintenance, it is few to influence oil well output, has remarkable economic efficiency.
Description of drawings
Fig. 1 is the assembling drawing of the utility model embodiment.
The specific embodiment
Below in conjunction with Fig. 1 the embodiment of the utility model is described.
Can know that by figure the embodiment of the utility model comprises upper flange 1, valve ball 2, valve seat 3, valve body 4, valve base joint 5, lower flange 6, baffle plate 7, valve seat 3 is installed in 4 li of valve bodies; Valve base joint 5 top screw threads are connected with valve body 4 bottom spiral shells 2 of valve balls on valve seat 3, and valve seat 3 lower surfaces are pushed down in valve base joint 5 upper surfaces; Insert in upper flange 1 endoporus on valve body 4 tops, valve body 4 tops and upper flange 1 welding, and insert in lower flange 6 endoporus valve base joint 5 bottoms; Valve base joint 5 bottoms and lower flange 6 welding, baffle plate 7 is fixed on valve body 4 tops, plays 2 motions of restriction valve ball; 2 of valve balls were in 3 last times of valve seat; Between baffle plate 7 and the valve ball 2 the 5-50mm distance is arranged, so that make valve ball be elevated to certain altitude, flow can unobstructedly flow away.
