Abstract
The utility model relates to a fat mouth is annotated to ground pipeline ball valve for well drilling, it is mainly by the parent, the block, big steel ball, plain joint, the necking down, a spring, little steel ball, connecting thread and notes fat mouth export constitution, after opening, annotates by the block fat, liquid begins through big conical boss from the upper portion of parent, down press the back to big steel ball, flow into inside the big conical boss, liquid flows out from the both ends of controlling of big conical boss lower part, the small circle toper boss at both ends about the fluid passage passageway gets into, flow into small circle toper boss after the fluid passage is down pressed little steel ball, conical boss lower part outbound flows from childhood, and liquid gets into the buffers of annotating fat mouth export upper portion afterwards, through annotating fat mouth export flow direction ball valve surface. The utility model discloses safeguarding that the maintenance is convenient, it is simple to dismantle, can effectively preventing to annotate the production that the blank pressing of fat mouth was lost efficacy, small circle toper boss adopts symmetric design, does not influence into fat speed, and the leakproofness is good.
Description
Technical field
This utility model relates to a kind of drilling well ground line thread ball valve greasing mouth in drilling engineering on surface line ball valve.
Background technology
Along with the fast development of China's economic, the demand of the petroleum gas energy is also being increased year by year.The startup of West-East National Gas Transmission Project has pulled domestic natural gas pipeline industry and the development of gas.The NG Pipeline Construction of China develops towards distance, heavy caliber, high pressure, the direction of automatization.Along with the development of pipeline industry, ball valve application in natural gas line is more extensive, and current ball valve proportion shared by natural-gas transfer pipeline is bigger, grasps its basic construction features the most well and could preferably ensure the safe and reliable of work.
Greasing mouth is extremely important external member on ball valve, can periodically inject grease to the sealing surface of ball valve by greasing mouth, it is achieved the internal maintenance of valve and maintenance.At present, the type of conventional greasing mouth has: plunger screw cap type greasing joint, two-piece type greasing joint, one chip greasing joint, one chip double check valve greasing joint, capping type unidirectional greasing joint, FLOWWOLF formula greasing joint.Pertinent literature is currently also had to carry out studying (Sun Guoan for greasing joint, Liu Lijia. a kind of supertension greasing joint: China, CN201320011008.9 [P] .2013.08.14), devise a kind of supertension greasing joint, can be used for less than-46 DEG C low temperature environments, and applicable pressure, ambient temperature are extensive.
Summary of the invention
This utility model purpose is to provide for a kind of simple in construction, good airproof performance, easy to use, and in use can overcome the generation that flanging lost efficacy.
This utility model be the technical scheme is that
This utility model one drilling well ground line thread ball valve greasing mouth, is mainly made up of parent, block, big steel ball, plain joint, necking down, spring, little steel ball, connection screw thread and the outlet of greasing mouth.Being provided with two sections in described parent and connect screw thread, one section of screw thread is connected with cap sealed；Another section is connected with ball valve body seal；A big steel ball, two little steel balls and three springs it are provided with in parent；Being provided with three conical boss in parent, fluid flows through these three cone boss and flows to inside ball valve.
Roundlet cone boss in described greasing mouth parent is symmetrical, the exit design width ratio import of roundlet cone boss little, but devises two roundlet cone bosses, does not affect the speed into fat.Conical boss in described parent designs in the middle part of parent, can effectively prevent the generation that flanging was lost efficacy.
Advantage of the present utility model: maintaining is convenient, dismantle generation simple, that can effectively prevent greasing mouth flanging to lose efficacy, and roundlet cone boss uses symmetric design, do not affects into fat speed, good airproof performance.
Accompanying drawing explanation
Fig. 1 is the sectional view of this utility model a kind of drilling well ground line thread ball valve greasing mouth.
Partial sectional view when Fig. 2 is Fig. 1 greasing.
In figure: 1. parent, 2. block, 3. big steel ball, 4. plain joint, 5. necking down, 6. spring, the least steel ball, 8. connect screw thread, the 9. outlet of greasing mouth.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further.
As it is shown in figure 1, this utility model one drilling well ground line thread ball valve greasing mouth, mainly it is made up of parent 1, block 2, big steel ball 3, plain joint 4, necking down 5, spring 6, little steel ball 7, connection screw thread 8 and greasing mouth outlet 9.Described parent 1 is provided with two sections and connects screw thread 8, and one section of screw thread is tightly connected with block 2；Another section is connected with ball valve body seal；3, two little steel balls 7 of a big steel ball and three springs 6 it are provided with in parent 1；Being additionally provided with three conical boss in parent 1, parent 1 limits the flowing of liquid in parent internal channel by these three cone boss and three steel balls, springs.In parent 1, the roundlet cone boss of design is symmetrical, the exit design width ratio import of roundlet cone boss little, but devises two roundlet cone bosses, does not affect the speed into fat.Big steel ball 3 in parent 1 and little steel ball 7 have the effect of non-return when liquid returns row.As in figure 2 it is shown, when greasing, the liquid import from parent 1 top initially enters great circle cone boss, liquid is by squeezing big steel ball 3 downwards, make big steel ball 3 move downward, inside great circle cone boss, flow out from the exit at two ends, left and right, great circle cone boss bottom；The liquid flowed out flows to roundlet cone boss top by passage, liquid is by squeezing the little steel ball 7 in roundlet cone boss downwards, little steel ball 7 is made down to move, so that liquid enters inside roundlet cone boss, flow out from the exit of roundlet cone boss bottom, liquid enters greasing mouth and exports the relief area on 9 tops, then from greasing mouth outlet 9 outflow.When needs pressure release, it is only necessary to rotating parent 1 counterclockwise, make the rotation that parent 1 is slight, the pressure in ball valve will be got rid of along gap, enormously simplify operation sequence.Owing to the motion of the steel ball in three conical boss is linear motion, such that it is able to well prevent the backflow of liquid, there is good sealing；Due to two roundlet cone bosses of design, make impurity be difficult to enter inside greasing mouth, thus improve the service life of greasing mouth.
