Abstract
The utility model relates to a ball valve and discloses an integrated double-blocking and double-discharging ball valve. The integrated double-blocking and double-discharging ball valve is characterized in that a main body component thereof is integrally designed, a packing box component is located on the upper portion of the main body component, a lower fixing shaft component is located on the lower portion of the main body component, a ball component is located in a cavity formed by the main body component, a valve seat component is located between the ball component and a sealing end cover component which is located between the valve seat component and the main body component, and the sealing end cover component is embedded in the main body component through an inner hexagon screw. By the adoption of the integrated design, two external leakage points are omitted, and structural length of the valve is shortened; meanwhile, a shell is sealed by the aid of pre-tension torque of a pipe flange bolt, so that the sealing end cover component is enabled to be in a state of low load or zero load on the long run, and service life of the valve is prolonged.
Description
Technical field
The utility model relates to a kind of ball valve, particularly the two pair ball-valves that stop up of a kind of integrated type.
Background technique
Since reform and opening-up, national economy rapid growth, scientific and technical innovation, autonomous innovation has become the main flow of domestic industry development.China's industry is just step by step to the future development of intensive style, energy-saving and emission-reduction, low-carbon (LC).The two ball-valves of two obstructions are widely used in the hydraulic system pipeline of the every profession and trades such as electric power, petrochemical industry, metallurgy, ocean, oil, natural gas, coal gas, pharmacy, higher to the seal request of valve.The two ball-valves of two obstructions are to design for replacing the complex form that in conventional tube, a plurality of valves connect, and the leakage point in minimizing system, realizes discharge, closing function fast.This ball valve has been saved installing space to greatest extent, has simplified installation procedure, has reduced the pressure of pipe-line system, facilitates instrument cleaning, reduces costs.But the existing double ball-valve structure of putting of two obstruction be take 3 stops as main, the mode that valve body connects is that bolt connects, and sealability is relatively poor.The technician of R&D institution and enterprise is constantly exploring, is studying, and wishes to develop a kind of two pair ball-valves that stop up of superior performance, although make some progress, still exists the technical barrier not yet overcoming in practice.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, provides a kind of integrated type two pair ball-valves that stop up, and valve body adopts integrated design, reduces two places external leakage point, has shortened the structure length of valve, good sealing effect, long service life.
The utility model solves the technological scheme that its technical problem adopts: contain Stuffing box assembly, lower stationary axle assembly, spheroid assembly, valve component, end cover assembly, body assembly, body assembly is the integrated design, Stuffing box assembly is positioned at body assembly top, lower stationary axle assembly is positioned at body assembly bottom, spheroid assembly is positioned at the formed cavity of body assembly, valve component is between spheroid assembly and end cover assembly, end cover assembly is between valve component and body assembly, by socket head screw, be embedded on body assembly, described end cover assembly contains thread ending cover, end cover, end cap fire proof seal pad, O type circle, short type injection safety check, end cover outer rim forms three joint shoulders, first segment shoulder is higher than the 3rd joint shoulder, second section shoulder is higher than first segment shoulder, first segment shoulder place is radially provided with groove, in groove, be provided with O type circle, between first segment shoulder and second section shoulder, be provided with end cap fire proof seal pad, second section shoulder is provided with short type injection safety check, the 3rd joint shoulder is provided with thread ending cover.
The beneficial effects of the utility model are: valve body adopts integrated design, reduce two places external leakage point, have shortened the structure length of valve.The sealing of housing simultaneously, by means of the pre-fastening moment of pipe flange bolt, is used end cover assembly for a long time in low-load or no load condition, has extended the working life of valve.
