The connector of cementing concrete head described in the utility model comprises a dismountable top connection 1, dismountable lower contact 2 and two joints is connected and fastening clamp nut 3 that wherein top connection 1 and lower contact 2 are hollow pipe fitting;
Top connection 1 is a hollow pipe fitting that internal diameter is identical; Top 4 at the pipe fitting outer round surface is screw thread, is threaded with the cementing head main body, and 5 cars become male-tapered in the bottom of pipe fitting outer round surface, between 4 and 5 and approach 5 above a projection is set support shoulder 10 (shoulders) with the nut 3 that is fixed and clamped:
Lower contact 2 is the hollow pipe fittings that internal diameter is different, and bottom 6 is the API sleeve pipe or the drilling rod button of standard, carries out being connected in the screw thread with sleeve pipe or drilling rod or outer the connection; Internal circular surfaces 7 cars on top become inner conical, match with the male-tapered 5 of top connection bottom, the outer cone 5 of top connection bottom is embedded among the female cone 7 on lower contact top, form the cooperation of two conical surfaces, the outer round surface on top is a steep-pitch thread 8, with the internal thread coupling of clamp nut 3.
Clamp nut 3 is socketed in the coupling part of top connection and lower contact, clamp nut external surface 9 is for hexagon or distributing equably can be for the projection of hammering, the upper design of circle has interior shoulder in the clamp nut, and is stuck on the half the circumference of the sleeve where it joins the shoulder 10 of top connection 1, with the position of the nut that is fixed and clamped; In the bottom of circle be designed to steep-pitch thread, match with the steep-pitch thread 8 of the outer round surface on lower contact 2 tops.
When clamp nut 3 was in the malcompression state, by the relative rotation of outer cone 5 in female cone 7, the top connection 1 that seat is gone in the lower contact 2 was rotated in 360 ° of scopes; When clamp nut was in tightening state, 1 of top connection can not be independent of that lower contact 2 is rotated or move.
For the ease of sealing, sealing ring 11 can be set between the conical contact face of two joints.In order to make sealing more effective, also can sealing ring be placed in one offering seal groove on the conical contact face arbitrarily.For example on internal conical surface 7, offer one or more seal grooves, sealing ring is put into seal groove, make sealing effectiveness better.
Connector of the present utility model compared with prior art has following outstanding effect:
(1) when connector of the present utility model is connected on the cementing head main body, can make union interface on the cementing head main body in 360 ° of scopes, rotate to any be convenient to that hose connects towards, made things convenient for constructing operation, be convenient to make cementing head to link to each other with cementing truck by hose, the operation save time, laborsaving, the work efficiency height.
(2) cost of connector is lower, and easy disassembling, upper and lower joint all are split designs, can prolong the application life of cementing head main body according to using abrasion condition to change easily, has saved cost.Cementing head is general in the prior art uses about 100 times just replacings, and after adopting connector of the present utility model, the cementing head main body can be used more than 400 times, has saved cost greatly.
(3) on the single-stage and multistage cementing head of connector of the present utility model applicable to all size,, be applied to the sleeve pipe of different button-types, a tractor serves several purposes by changing lower contact.
