Abstract
A high-pressure sand preventing cut-off device comprises a valve cover which is connected with a valve body through threads, and a gasket is arranged between the valve cover and the valve body. The high-pressure sand preventing cut-off device is characterized in that a ball barrel is arranged on the lower portion of the valve cover, the ball barrel is integrally connected with the upper valve cover and a lower valve seat through threads and is embedded into an inner cavity of the valve body, a ball is arranged in the ball barrel and freely moves in the ball barrel, and a rubber ring is arranged on the outer side of the valve seat in a sleeving mode. The valve seat is made of titanium and tungsten alloy, and the ball barrel and the ball are both made of 1Cr18Ni9Ti. The high-pressure sand preventing cut-off device is simple in structure, reasonable in design and convenient to repair, dismount and mount, work efficiency is improved, and production cost is reduced.
Description
Technical field
The utility model relates to a kind of high pressure sand control guillotine, belongs to the technical field of oil extraction in oil field parts aspect.
Background technique
At present, known high pressure sand control guillotine, is made up of valve body, valve seat, spheroid and valve gap.Valve gap is connected by screw thread mode with valve body, and spheroid is directly put into body cavity, tightens valve gap.The defect of this device is, in the time safeguarding and clean inner chamber, package unit must be disassembled and could clean and safeguard from pipeline, if valve seat damages to some extent or can not dismounting and change can only scrap.Spheroid and valve seat through after a while back and forth sealing very easily make spheroid and valve seat wear and tear simultaneously, wearing and tearing just can not be self-styled when excessive.
Summary of the invention
The deficiency existing for the problems referred to above, the purpose of this utility model is, a kind of high pressure sand control guillotine is provided.
A kind of high pressure sand control guillotine, comprise that valve gap (1) is threaded with valve body (2), between valve gap (1) and valve body (2), be provided with packing ring (6), it is characterized in that: be provided with ball cylinder (3) in the bottom of valve gap (1), described ball cylinder (3) is spirally connected and is integrated with the valve gap (1) of top setting and the valve seat (5) of bottom setting, embeds valve body (2) inner chamber; Be provided with spheroid (4) in the inside of ball cylinder (3), described spheroid (4) is in the internal freedom activity of ball cylinder (3); Be set with cushion rubber (7) in the outside of valve seat (5).
Described valve seat (5) adopts titanium-tungsten material to be made.
Described ball cylinder (3) and spheroid (4) all adopt chromium 18 nickel nine titaniums to be made.
The utility model has, simple in structure, reasonable in design, and maintenance, easy accessibility, improved working efficiency, reduced cost of production.Valve seat adopts titanium-tungsten material to be made, and hardness is higher than spheroid, even if spheroid has compared with galling, valve seat can not be subject to large impact, and the life-span of this device can reach the more than 4 times of single flow device.
Brief description of the drawings
Fig. 1 is sectional structure schematic diagram of the present utility model.
In figure: valve gap 1, valve body 2, ball cylinder 3, spheroid 4, valve seat 5, packing ring 6, cushion rubber 7.
Embodiment
As shown in Figure 1, a kind of high pressure sand control guillotine, comprise that valve gap 1 is threaded with valve body 2, between valve gap 1 and valve body 2, be provided with packing ring 6, it is characterized in that, be provided with ball cylinder 3 in the bottom of valve gap 1, described ball cylinder 3 is spirally connected and is integrated with the valve gap 1 of top setting and the valve seat 5 of bottom setting, embeds valve body 2 inner chambers.Be provided with spheroid 4 in the inside of ball cylinder 3, described spheroid 4 can be interior freely movable at ball cylinder 3.Make package unit be divided into two-part.Be set with cushion rubber 7 in the outside of valve seat 5.Dextrorotation valve gap 1, makes ball cylinder 3, spheroid 4 enter valve body 2 inner chambers together with valve seat 5, the sealing by twice cushion rubber 7 realizations on valve seat 5 with valve body 2.
This device uses after certain hour, when inner silt particle too much or parts damages need to clear up and change, left-handed valve gap 1, valve gap 1 drives ball cylinder 3, spheroid 4, valve seat 5 to take out fast, clear up or change, avoid well known device also to need to pull down the overall defect that just can take out inner components, not only improved working efficiency but also reduced cost of production.
Described valve seat 5 adopts tungsten-titanium alloy, also make cemented carbide material be made, described ball cylinder 3 and spheroid 4 all adopt chromium 18 nickel nine titaniums to be made, and make this device improve 3-4 doubly working life than well known device working life, both save cost, improved again efficiency.
The hardness of valve seat 5 is higher than spheroid 4, even if spheroid 4 has wearing and tearing, valve seat 5 can not be subject to large impact yet, and the life-span can reach 4 times of single flow device.
When medium flows into from valve seat 5 directions, spheroid 4 is moved in trying hard to recommend of the mobile generation of medium itself, and spheroid 4 departs from valve seat 5, and medium flows into multi-purpose station pipeline from ball cylinder areole, and when medium stops output, the refluence pressure of medium makes spheroid 4 returns and valve seat 5 carry out quick-sealing.This device is the mobile generation power of tube road medium itself and opening and closing automatically, and its Main Function is to prevent that medium from flowing backwards, and prevents releasing of pump and drive motor reversion and container inner medium.
Claims (3)
1. a high pressure sand control guillotine, comprise that valve gap (1) is threaded with valve body (2), between valve gap (1) and valve body (2), be provided with packing ring (6), it is characterized in that: be provided with ball cylinder (3) in the bottom of valve gap (1), described ball cylinder (3) is spirally connected and is integrated with the valve gap (1) of top setting and the valve seat (5) of bottom setting, embeds valve body (2) inner chamber; Be provided with spheroid (4) in the inside of ball cylinder (3), described spheroid (4) is in the internal freedom activity of ball cylinder (3); Be set with cushion rubber (7) in the outside of valve seat (5).
