Abstract

The utility model discloses a dry ash adjusting valve of a continuous cement slurry mixer. The dry ash adjusting valve comprises a valve body which is arranged horizontally, wherein an ash inlet is formed in the upper half face of the valve body; an ash outlet is formed in the lower half face of the valve body; a valve core is arranged in an inner cavity of the valve body; the valve core is provided with two sections of plug cock belts; the lower part of the ash outlet of the valve body is communicated with the mixing cavity of the continuous mixer by a straight pipe and a union joint. The device provided by the utility model is good in processing manufacturability; the valve core can be rotated by adopting an automatic or manual manner so that opening change and the change of an ash inlet amount of the ash inlet of the valve body tend to linear changes, and the control precision of the ash inlet amount is improved.

Description

The dry ash control valve of the continuous blender of cementing slurry

Technical field

The utility model belongs to oil gas field well cementation equipment technology field, relates to the dry ash control valve of the continuous blender of a kind of cementing slurry.

Background technology

In the drilling and well completion process in oil, gas field, frequent need to on-the-spotly the preparation be contained being mixed evenly of different material, well behaved cementing slurry, and the continuous blender that has thus the control of high accuracy ash quantity fed seems particularly important.Existing oil gas field is used the dry ash control valve of continuous blender, the employing vertical mode is installed, ash inlet is horizontal direction, spool is provided with the grey hole of mistake of the shapes such as oval, processing technology is poor, and spool often turns over same angle, and spool ash flue jaws opening changes not identical, cross the poor linearity of grey opening variation and the dry ash amount of feeding, reduced the degree of regulation of ash quantity fed.

The utility model content

The purpose of this utility model is to provide the dry ash control valve of the continuous blender of a kind of cementing slurry, has solved the poor linearity of the grey opening variation of the mistake existed in the prior art and the dry ash amount of feeding, has reduced the problem of ash quantity fed degree of regulation.

The technical scheme that the utility model adopts is, the dry ash control valve of the continuous blender of a kind of cementing slurry, comprise horizontally disposed valve body, at the valve body upper half plane, is provided with ash inlet, and under valve body, demifacet is provided with ash hole; Be provided with spool at body cavity, spool is provided with two sections cock bands; The ash hole bottom of valve body is communicated with the hybrid chamber of continuous blender by straight tube and union joint.

The dry ash control valve of the continuous blender of cementing slurry of the present utility model, its characteristics also are:

Valve body and spool are columnar structured.

Ash inlet is the square opening structure, and the cock band is the square block structure, and the opening of one of them cock band is greater than the ash inlet opening, and the opening of another cock band is less than the ash inlet opening.

Be communicated with rinse mouth on the wall of valve body.

Be communicated with breather valve on the wall of straight tube.

The beneficial effects of the utility model are, on the valve body housing, ash-inlet hole are set, and are provided with the cock band on spool, are regular square structure, and processing technology is good; Can adopt automatic or manual mode rotary spool, by the cock on spool, bring the grey hole of the mistake of blocking gradually or opening on valve body, implement the ash amount and send to.Its maximum characteristics are that ash inlet adopts square structure, can turn over same angle by the every valve body relatively of Reliable guarantee spool, the grey opening variable quantity of the mistake of ash-inlet hole is identical, makes the opening variation of valve body ash-inlet hole be tending towards linear change with ash quantity fed, has improved the control accuracy of ash quantity fed.

The accompanying drawing explanation

Fig. 1 is that the utility model device is arranged on the structure schematic diagram on continuous blender;

Fig. 2 is the structural representation of the dry ash control valve in the utility model device;

Fig. 3 is that A in Fig. 2 is to view (schematic diagrames of ash inlet 8 lines of vision).

In figure, 1. advance ash and take over, 2. valve body, 3. spool, 4. rinse mouth, 5. breather valve, 6. straight tube, 7. union joint, 8. ash inlet, 9. ash hole, 10. cock band, 11. continuous blenders.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.

With reference to Fig. 1, Fig. 2, Fig. 3, the structure of the utility model device is, comprise horizontally disposed valve body 2, valve body 2 is columnar structured, be provided with and advance ash adapter 1 ash inlet communicated 8 at valve body 2 upper half planes, ash inlet 8 is the square opening structure, and 2 times demifacets of valve body separately are provided with ash hole 9 along the diagonal position of diameter; Be provided with spool 3 at valve body 2 inner chambers, spool 3 is columnar structured, and spool 3 is provided with two sections cock bands 10, and cock band 10 is square structure, and the opening of one of them cock band 10 is greater than ash inlet 8 openings, the opening of another cock band 10 is less than ash inlet 8 openings; Ash hole 9 bottoms of valve body 2 are communicated with the hybrid chamber of continuous blender by straight tube 6 and union joint 7; Be communicated with rinse mouth 4 on the wall of valve body 2, be communicated with breather valve 5 on the wall of straight tube 6.

The utility model device, by outside angling cylinder or manual mode rotational valve core 3, make the cock band 10 of spool 3 block gradually or open the ash inlet 8 on valve body 2, realize that dry ash enters the cavity between valve body 2 and spool 3 from ash inlet 8, and enter straight tube 6 through the ash hole 9 of valve body 2, lead to the hybrid chamber of continuous blender.

During rotational valve core 3, the linear grey opening of mistake that changes valve body ash inlet 8, realize that the ratio of the dry ash amount of feeding is regulated, and improves the degree of regulation of the dry ash amount of feeding.
