Abstract
The utility model discloses a water faucet which is used for petroleum drilling and well repairing working. An original casting shell body is improved to be a forging shell body, namely a shell body part is formed by a forged forge piece through heat treatment, defect detection and machining, and main load bearing pieces in the water faucet are all forge pieces. Due to the fact that comprehensive mechanical properties of the forge pieces are higher than comprehensive mechanical properties of castings by one level, use properties and safe properties are greatly improved, and therefore integral reliability and full-working-condition safe reliability of a water faucet product are improved, the water faucet is capable of being applicable to low-temperature environment, and a quality level of the product is greatly improved.
Description
Technical field
The utility model relates to a kind of oil drilling and workover swivel, particularly a kind of water tap that forges housing.
Background technology
Key equipment when water tap belongs to oil drilling and well workover in its Hoisting System, its effect are when drilling well and workover treatment, when bearing top load, keeping the drilling rod rotation, inject high-pressure slurry in well.Because operation particularity of working conditions and importance have very high requirement to its mechanical performance, especially need absolute security performance.At present in the water tap that in industry uses, what the housing part of one of its main bearing member adopted is cast member, because the mechanical performance poor controllability of foundry goods self can not satisfy the security performance needs fully, reliability is not high, especially has potential safety hazard under ultra-low temperature surroundings.
Summary of the invention
The utility model provides the safe water tap that a kind of main bearing member all is forging, the key problem in technology that solves mainly is original foundry goods housing is improved to the forging housing, the source that is housing component be by through the forging that forges again through heat treatment, carrying out flaw detection and machining, make the main bearing part in the water tap all use forging.Because the comprehensive mechanical performance of forging itself exceeds a class than foundry goods, the institute so that its functional performance and safety be greatly improved, thereby improved the whole full working condition safety reliability of water tap product, more can be applicable to low temperature environment, promoted the credit rating of product greatly.
Description of drawings
Be example with the SL225 water tap below, this accompanying drawing is described further.
This accompanying drawing is half section structure chart of the present utility model.The utility model mainly is made up of drop handle (1), gooseneck (2), support (3), washing pipe (4), drop handle pin (5), housing (6), thrust bearing (7), central tube (8) and protection joint (9).Its middle shell (6) is the solid forging part.Drop handle (1) is connected with housing by drop handle pin (5); central tube (8) acts on load on the housing (6) by thrust bearing (7); protection joint (9) directly is connected the lower end of central tube (8), and an end of washing pipe (4) links to each other with central tube (8), and the other end and gooseneck (2) join.Central tube (8) can rotate freely in housing (6).The through hole at center is in order to the high-pressure slurry that circulates.
The specific embodiment
Below in conjunction with accompanying drawing, be example with the SL225 water tap, utility model is described further:
The utility model mainly is made up of drop handle (1), gooseneck (2), support (3), washing pipe (4), drop handle pin (5), housing (6), thrust bearing (7), central tube (8) and protection joint (9).Drop handle (1) is connected with housing by drop handle pin (5); central tube (8) acts on load on the housing (6) by thrust bearing (7); protection joint (9) directly is connected the lower end of central tube (8), and an end of washing pipe (4) links to each other with central tube (8), and the other end and gooseneck (2) join.Central tube (8) can rotate freely in housing (6).The through hole at center is in order to the high-pressure slurry that circulates.
Housing (6) is the solid forging part, be to heat-treat again through after forging, be assembled into water tap after machining and the nondestructive testing with selected metal material, make this crucial bearing part have high-strength comprehensive mechanical performance, consequently the main bearing part in the water tap all uses forging.Thereby make the global reliability of water tap and the raising that security performance obtains essence.
Claims (1)
1. the water tap used of an oil drilling and well workover; comprise drop handle, gooseneck, support, washing pipe, drop handle pin, housing, thrust bearing, central tube and protection joint; drop handle is connected with housing by the drop handle pin; central tube acts on load on the housing by thrust bearing; the protection joint directly is connected the lower end of central tube; one end of washing pipe links to each other with central tube; the other end and gooseneck join; central tube can rotate in housing, it is characterized in that: the housing part of one of main bearing part is forging.
