The specific embodiment
As shown in Figure 1, it comprises that the upper end is provided with internal thread 11, the lower end is provided with the cylindrical body 1 of external screw thread 12, be equipped with in the body 1 by pillar 2, spring 3, valve seat 4, lock dog 5, the Antisplash machanism that resets certainly that intermediate seat 6 and little valve body 7 constitute, pillar 2 is positioned at body 1 end opening upper shaft to being slidingly mounted on body 1, spring 3 is positioned at the outside that body 1 is enclosed within pillar 2, the lower surface roof pressure is on the inner face of body 1, the upper shaft that valve seat 4 is positioned at spring 3 is installed on body 1 inwall and is enclosed within the outside of pillar 2 to slipper seal, the lower surface of valve seat 4 is pressed in the upper end of spring 3, lock dog 5 is installed in the lock dog groove 13 on valve seat 4 top bodies 1 inwall, the upper shaft that intermediate seat 6 is positioned at lock dog 5 is to being slidingly mounted on body 1 and being enclosed within the outside of pillar 2, and little valve body 7 is installed in the upper end of pillar 2.
Be welded with a plurality of wear-resisting points 14 on body 1 outer wall.
It also comprises the anti-network blocking 8 that is inserted into from bottom to top in the body 1, and anti-network blocking 8 is the goblet that falls under shed that roof and sidewall are provided with a plurality of through holes 81, and anti-network blocking 8 end opening outer walls are provided with and are subjected to the spacing wild card in body 1 lower surface along 82.
Valve seat 4 is for being provided with seal groove 41 with outer wall that body 1 slipper seal cooperates and sealing ring 42 is installed, suitable for readingly goes up the ring bodies that the position of matching with intermediate seat 6 is up big and down small inner conical surface.
Lock dog 5 constitutes by some, and the each several part of lock dog 5 outwards supports with elastic spring 51 and is installed in the lock dog groove 13 by being installed in hole on lock dog 5 inwalls.
Axially have mud hole 61, upper end periphery greater than mated position pillar 2 external diameters centered by the intermediate seat 6 and be provided with ring bodies with body 1 inwall axial sliding fit back-up block 62 separately, back-up block 62 is subjected to lock dog 5 spacing downwards, the position that the suitable for reading and little valve body 7 in intermediate seat mud hole 61 matches is up big and down small inner conical surface, and the position that intermediate seat 6 lower end outer walls match with valve seat 4 is upper coarse and lower fine male cone (strobilus masculinus).
The steamed bun capitulum of little valve body 7 for being sleeved on pillar 2 upper ends from the top down and locking mutually by bearing pin 71 radially, the position of matching with intermediate seat 6 in little valve body 7 lower ends is upper coarse and lower fine male cone (strobilus masculinus).
The utility model operating principle:
Kelly bar anti-network blocking 8 when resetting anti-splash device drilling well work is backed down little valve body 7, intermediate seat 6 and valve seat 4 by pillar 2 automatically, and drilling fluid passes through from little valve body 7, intermediate seat 6 and valve seat 4 during turn on pump,, make the unimpeded mistake of drilling liquid flow.After proposing the brill termination of pumping, dismantle kelly bar from resetting anti-splash device and lower end drilling tool connecting thread, anti-network blocking 8 is fallen, little valve body 7, intermediate seat 6 and valve seat 4 are closed drilling fluid automatically and can not be dropped, make driller keep good working environment, platform does not have mud, guarantees sanitation and hygiene.
Kelly bar is not installed anti-blocking net 8 when resetting anti-splash device work, when pump pressure was raised to 0.2～0.5MPa, valve seat 4 left intermediate seat 6 during turn on pump.At this moment, the drilling fluid passage is opened.When pump pressure continues to be raised to 2MPa, the spring 3 stressed 2.23kN that reach maximum load.At this moment, valve seat 4 is in extreme lower position, and namely valve seat 4 moves down apart from intermediate seat 6 30 ㎜.Because spring 3 is pressed and height, so no matter how high pump pressure is, the position of valve seat 4 no longer changes.Therefore, when normal turn on pump circulation time, total distance that keeps 30 ㎜ between valve seat 4 and the intermediate seat 6, so part is difficult for being washed out." kelly bar is from the resetting anti-splash device " life-span of this structure can reach hundreds of individual hour.
The utility model advantage:
1), kelly bar is from the advantage of the comprehensive mud plash proof valve of anti-splash device that resets, kelly bar is welded with wear-resisting point from the plash proof valve external surface that resets, the wear-resisting point 14 that has increased kelly bar automatic runback device external surface makes its product increase application life, makes body 1 not easy to wear, and it is reliable and stable to make tong.
2), anti-network blocking 8 played anti-bulky grain and minced and fall the shaft bottom, improves the application life of drill bit.
3), kelly bar unloads the not time spent from the anti-splash device that resets, and puts on the special joint thread protector, in the winter time can the assurance device opening during low temperature, prevent from that the winter low temperature handle assembly from freezing can not work.
4), kelly bar replaced anti-blocking valve from the anti-splash device that resets, and played the many usefulness of a device, saves and connects the drilling tool time, saves national purchase cost, is that country saves fund.
