Abstract
A kelly cock valve comprises a body (1), a first baffle ring (2), an upper ball seat (3), a second baffle ring (4), a spherical valve (5), a lower ball seat (6), a spring (7), a stop block (8), a knob(9) and a poking block (10), wherein hard sealing rings (31, 61) matched with the spherical face of the spherical valve (5) are respectively arranged in a contact position between the upper ball seat(3) and the spherical valve (5) and in a contact position between the lower ball seat (6) and the spherical valve (5) . A material with a rigidity higher than the basal bodies of the upper ball seatand the lower ball seat is adopted for the spherical faces of the upper ball seat and the lower ball seat, so as to improve the rigidity of the spherical faces of the upper ball seat and the lower ball seat, and reduce the wear rate with the spherical valve; and the kelly cock valve with firmness, durability and long service life can effectively prevent the occurrence of various accidents, therebyimproving the operation security and guaranteeing life safety and property safety.
Description
Technical field
The utility model relates to petroleum machinery, particularly a kind of kelly cock.
Background technology
Kelly cock also is kelly bar cock or drilling pipe safety valve, drilling fluid can not have pressure drop ground and freely flows through this valve, this class valve is as drilling pipe safety valve, perhaps be contained in the control blowout prevention of kelly bar top, perhaps be contained in the kelly bar below, when unloading, kelly bar prevents that drilling fluid runs off, adopt metal and intermetallic cooperatively interacting to realize sealing function between the upper ball base of existing kelly cock and lower ball base and ball valve, because the hardness of ball valve is with respect to the hardness height of upper ball base and lower ball base, so relative displacement takes place each other to produce when rubbing, the contacted sphere abrasion of upper ball base and lower ball base and ball valve is bigger, cause kelly cock not sturdy and durable, application life is short.
The utility model content
Technical problem to be solved in the utility model is at existing kelly cock short shortcoming in application life, and a kind of kelly cock of sturdy and durable, long service life is provided.
Technical solution of the present utility model is: it comprises body, baffle ring one, upper ball base, baffle ring two, ball valve, lower ball base, spring, block, knob and shifting block, baffle ring one, upper ball base, baffle ring two, ball valve, lower ball base and spring are installed in the mesopore of body from the top down, spring housing is on lower ball base, its top and bottom are pressed in respectively on lower ball base and the body, block, knob and shifting block are installed in the control mouth of body, knob links to each other with shifting block, shifting block links to each other with ball valve, is respectively equipped with the hard joint ring that matches with the sphere of ball valve at upper ball base and lower ball base with the contacted position of ball valve.
Technique effect of the present utility model is: it passes through the sphere place employing of upper ball base and lower ball base and the higher material of matrix hardness of upper ball base and lower ball base, improved the hardness of upper ball base and lower ball base sphere, reduced wear rate with ball valve, has advantage sturdy and durable, long service life, can effectively prevent the generation of various accidents, improve operational security, guaranteed the safety of lives and properties.
Description of drawings
Fig. 1 is the axial sectional view of the utility model embodiment;
Fig. 2 is that the utility model embodiment A-A is to sectional view.
The specific embodiment
As Fig. 1, shown in Figure 2, it comprises body 1, baffle ring 1, upper ball base 3, baffle ring 24, ball valve 5, lower ball base 6, spring 7, block 8, knob 9 and shifting block 10, baffle ring 1, upper ball base 3, baffle ring 24, ball valve 5, lower ball base 6 and spring 7 are installed in the mesopore of body 1 from the top down, spring 7 is enclosed within on the lower ball base 6, its two ends are pressed in respectively on lower ball base 6 and the body 1, block 8, knob 9 and shifting block 10 are installed in the control mouth of body 1, knob 9 links to each other with shifting block 10, shifting block 10 links to each other with ball valve 5, is respectively equipped with the hard joint ring 31 that matches with the sphere of ball valve 5 at upper ball base 3 and lower ball base 6 with ball valve 5 contacted positions, 61.
By improvement to product structure, the sphere place of upper ball base 3 and lower ball base 6 is adopted and the suitable material of ball valve 5 hardness, thereby improved the hardness of upper ball base 3 and lower ball base 6 spheres, reduced the wear rate of upper ball base 3 and lower ball base 6 spheres and ball valve 5, the application life of having improved product.
