Abstract

The utility model relates to a cement truck outlet pipeline anti-overflow device. The problem that residual liquid in an outlet pipeline overflows to a well site after the well washing of the existing cement truck is finished is mainly solved. The method is characterized in that: the pipeline joint is characterized in that a valve rod seat (7) is connected to the inner portion of the right end of the main body (2), a valve rod (6) is arranged inside the valve rod seat (7), a valve head (3) is fixed to the left end of the valve rod (6), a pressure spring (5) is arranged between the valve head (3) and the valve rod seat (7), and the valve head (3) is matched with the right end of the pipeline joint (1) through an inclined plane. This cement truck outlet pipeline anti-overflow device can ensure that surplus liquid can not overflow to the well site in the cement truck outlet pipeline, has solved environmental pollution's problem.

Description

A kind of cementing truck outlet line Anti-overflow device
Technical field
The utility model relates to oilfield, is a kind of cementing truck outlet line Anti-overflow device specifically.
Background technique
Current oil field is after washing well, and in cementing truck outlet line, remaining liq often can overflow on well site, befouling environment.
Summary of the invention
The deficiency overflowed on well site is known from experience in order to overcome the raffinate of existing cementing truck after well-flushing in outlet line, the utility model provides a kind of cementing truck outlet line Anti-overflow device, this cementing truck outlet line Anti-overflow device can guarantee that in cementing truck outlet line, remaining liq can not overflow on well site, solves the problem of environmental pollution.
The technical solution of the utility model is: a kind of cementing truck outlet line Anti-overflow device, comprise pipe joint, pipe joint right-hand member is connected with main body, described main body right-hand member is internally connected with valve rod base, valve rod base inside is provided with valve rod, valve rod left end is fixed with valve head, is equipped with pressure spring between described valve head and valve rod base, and valve head is matched by inclined-plane with pipe joint right-hand member.
The utility model has following beneficial effect: owing to taking such scheme, this Anti-overflow device is connected on cementing truck outlet line, when well-flushing, washing well liquid can smoothly by carrying out well-flushing, this device can be closed by spring-compressed valve head after well-flushing, cementing truck outlet line is thoroughly closed, guarantee that in cementing truck outlet line, remaining liq can not overflow on well site, solves the problem of environmental pollution.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-pipe joint in figure, 2-main body, 3-valve head, 4-righting handle, 5-pressure spring, 6-valve rod, 7-valve rod base, 8-liquid outlet, 9-liquid-inlet.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of cementing truck outlet line Anti-overflow device, comprises pipe joint 1, and pipe joint 1 left end is connected with cementing truck outlet line, and right-hand member is connected with main body 2, and main body 2 is externally connected to righting handle 4, can for hand-held when connecting.Described main body 2 right-hand member end is connected with Christmas tree casing gate, and on the right side of main body 2, inside has been threaded connection valve rod base 7, and valve rod base 7 inside is provided with valve rod 6, valve rod base 7 has the liquid outlet 8 of several axis between valve rod 6 and valve rod base 7 slidably.Valve rod 6 left end is fixed with valve head 3, is equipped with pressure spring 5 between described valve head 3 and valve rod base 7, and valve head 3 is matched by inclined-plane with pipe joint 1 right-hand member, forms the valve head valve seat of sealing mutually, and pipe joint 1 inside axially has liquid-inlet.
This Anti-overflow device is connected between cementing truck outlet line and Christmas tree casing gate, when well-flushing, flushing fluid is entered by liquid-inlet 9, compression valve head 3, valve head 3 is opened by the elastic force overcoming pressure spring 5, liquid enters Christmas tree casing gate by liquid outlet 8, thus makes flushing fluid inflow shaft bottom carry out well-flushing.After well-flushing, cementing truck termination of pumping, pipeline internal pressure declines, now, pressure spring 5 compresses valve head 3, makes to seal between the valve seat of valve head 3 and pipe joint 1 right-hand member, guarantee that in cementing truck outlet line, remaining liq can not overflow on well site, solves the problem of environmental pollution.

Claims (1)

1. a cementing truck outlet line Anti-overflow device, comprise pipe joint (1), pipe joint (1) right-hand member is connected with main body (2), be characterised in that: described main body (2) right-hand member is internally connected with valve rod base (7), valve rod base (7) inside is provided with valve rod (6), valve rod (6) left end is fixed with valve head (3), be equipped with pressure spring (5), and valve head (3) is matched between described valve head (3) and valve rod base (7) by inclined-plane with pipe joint (1) right-hand member.
