Description
Technical field
The utility model belongs to petroleum machinery field, is specifically related to a kind of tapering linear sealing combination unit containing secondary seal.
Background technology
At present, the grease pouring valve of domestic production mostly is the sealing of single sealing hard sphere, the material that it is selected, comprise the condition of work can not meet sealing life at high pressure or rugged environment, produced the phenomenon of " run, leak " grease, do not have the lubrication of grease to whole valve, whole valve is used, produced very large negative impact.
Utility model content
Technical problem to be solved in the utility model is to overcome defect of the prior art, a kind of tapering linear sealing combination unit containing secondary seal is provided, can solve well scene " thorn leaks " phenomenon, can realize safe and efficient detachable maintaining with pressure and change high-pressure grease pouring valve simultaneously, avoided tradition need closing well even kill-job realize replacing high-pressure grease pouring valve, solved the whole lubricating system sealing problem of valve.
For solving the problems of the technologies described above, the utility model provides a kind of tapering linear sealing combination unit containing secondary seal, comprise high-pressure grease pouring valve, high-pressure grease pouring valve comprises nut sleeve, grease pouring valve body, spring, steel ball and two ends are the seal of the conical surface, nut sleeve is arranged on grease pouring valve body, steel ball and spring are placed in grease pouring valve chamber body, steel ball by spring supporting on the inner chamber of grease pouring valve body, steel ball and grease pouring valve chamber body form shape linear sealing, seal is by steel ball, pressure mounting of the spring is on the top of grease pouring valve body, seal and grease pouring valve body form linear sealing, also comprise secondary sealer, secondary sealer comprises sealing device body, sealing thimble and restriction pad, sealing device body is connected with the adapted to injection system of valve, restriction pad is positioned at the end of sealing device body, sealing thimble is fitted in sealing device body interior by restriction pad.
As further improvement of the utility model, grease pouring valve body is the mode card means of press seals body that adopts integrated hydraulic moulding.
As further improvement of the utility model, restriction pad is along the circumference extrusion modling of sealing device body.
As further improvement of the utility model, nut sleeve is arranged on grease pouring valve body by engage thread.
The beneficial effect that the utility model reaches is: secondary sealer and high-pressure grease pouring valve are set in adapted to injection system, under the working environment of high pressure, rely on this structure both to realize the smooth and easy of injection moulding, secondary sealer is realized oppositely sealing after injection moulding simultaneously, the sealing of Wei Qian road high-pressure grease pouring valve has increased reliable insurance, guarantee the functional safety of adapted to injection system, extend its service life.
Accompanying drawing explanation
