Abstract
The utility model relates to a plug valve structure with a sealing bush, which comprises a valve body. A plug cock is mounted in the valve body, a bush is disposed on the plug cock, a sealing valve bonnet is arranged at a position on a plug cock shaft section on the upper side of the valve body, a sealing cam is disposed between the sealing valve bonnet and the plug cock shaft section, an oblique threaded through hole is arranged on the sealing valve bonnet, a bolt is disposed in the oblique threaded through hole, an oblique groove is arranged at a position, which corresponds to the oblique threaded through hole, of the sealing cam, a metal partition board is arranged at a position, which contacts with the valve body, of the sealing valve bonnet, and a triangular cushion is arranged on the lower side of the metal partition board. When the sealing performance of the plug valve structure is poorer due to abrasion, the sealing cam is pressed tightly by means of adjusting the bolt, accordingly tight sealing effect is guaranteed, and leakage is prevented.
Description
Technical field
The utility model relates to a kind of structure of valve, especially relates to a kind of seal cartridge stopcock structure that is easy to regulate sealability.
Background technique
Stopcock is widely used in oilfield exploitation, conveying and the concise equipment with characteristics such as simple in structure, that switch is rapid, fluid resistance is little, also is widely used in petrochemical industry, chemical industry, coal gas, rock gas, liquefied petroleum gas (LPG), HVAC industry and the general industry simultaneously.The basic structure of stopcock: stopcock is the rotary valve of closure member or plunger shape, with the band through hole cock body as open-shut device, to turn 90 degrees the passway that makes on the cock body identical with the passway on the valve body or separate by revolving, realize opening or closing, common stopcock seals with direct contact the between valve body by accurately machined metal cock body, so sealing is relatively poor, hoisting capacity is big, wearing and tearing easily are not easy after the leakage to regulate.
Summary of the invention
It is superior and be easy to regulate the seal cartridge stopcock structure of its sealing that technical problem to be solved in the utility model provides a kind of sealability.
The technical scheme in the invention for solving the technical problem is: a kind of seal cartridge stopcock structure, comprise valve body, cock is installed in the valve body, cock is provided with lining, the position of cock shaft part is provided with sealed valve cap above valve body, be provided with sealed cam between sealed valve cap and cock shaft part, described sealed valve cap is provided with an oblique tapped through hole, tiltedly is provided with bolt in the tapped through hole.
Bolt produces downward power to sealed cam for convenience, and described sealed cam is provided with skewed slot in the position corresponding with oblique tapped through hole.
In order to increase the sealability of stopcock structure, described sealed valve cap is being provided with metal partion (metp) with the valve body position contacting, and the metal partion (metp) below is provided with delta-ring.
The beneficial effects of the utility model are: the sealing in this kind stopcock structure, is regulated bolt and is made sealed cam compress in the variation owing to wear and tear, and has ensured that sealing is tight, has prevented to leak.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing at the utility model bolt and oblique tapped through hole place.
Among the figure: 1, sealed cam 2, bolt 3, sealed valve cap 4, cock 5, metal partion (metp) 6, delta-ring 7, lining 8, valve body 2-1, oblique tapped through hole 2-2, skewed slot
Embodiment
A kind of as depicted in figs. 1 and 2 seal cartridge stopcock structure, comprise valve body 8, cock 4 is installed in the valve body 8, cock 4 is provided with lining 7, the position of cock 4 shaft parts is provided with sealed valve cap 3 above valve body 8, be provided with sealed cam 1 between sealed valve cap 3 and cock 4 shaft parts, described sealed valve cap 3 is provided with an oblique tapped through hole 2-1, tiltedly is provided with bolt 2 in the tapped through hole 2-1; Described sealed cam 1 is provided with skewed slot 2-2 in the position corresponding with oblique tapped through hole 2-1; Described sealed valve cap 3 is being provided with metal partion (metp) 5 with valve body 8 position contacting, and metal partion (metp) 5 belows are provided with delta-ring 6.
Long and when stopcock service time because during phenomenon that wearing and tearing take place to leak, bolt 2 is screwed in, one end of bolt 2 is pushed down sealed cam 1 moves downward it, sealed cam 1 compresses metal partion (metp) 5, metal partion (metp) 5 passes to power on delta-ring 6 and the lining 7 successively, compress delta-ring 6 and lining 7, delta-ring 6, lining 7 are sealed closely with valve body 8, prevent to reveal.
