Description
Technical field
The utility model relates to a kind of mechanical design field, and in particular, it relates to a kind of band cap grease pouring valve.
Background technique
Grease pouring valve is generally applied on the equipment such as big machinery, petrochemical industry equipment, ball valve, plane gate valve, is for the device to machinery filling seal grease; Existing grease pouring valve is generally comprised of valve body, spring, steel ball and bonnet, valve body comprises fat hole and grease-outlet hole, and in valve body, offer the greasing passage being all communicated with fat hole and grease-outlet hole, and the bore of fat hole and grease-outlet hole is all less than the bore of greasing passage, bonnet is arranged on one end of the corresponding fat hole of valve body, thereby plays seal action; Steel ball and spring are all arranged in greasing passage, spheroid is arranged on one end of the corresponding fat hole of greasing passage, spring one end is connected with spheroid and the other end is conflicted on grease-outlet hole, spring in compressive state, steel ball is blocked greasing passage under the elastic force effect of spring; Grease pouring valve in use, is first backed out bonnet, then from fat hole greasing, when greasing pressure is greater than the elastic force of spring, steel ball is backed down, thereby seal gease is flowed out from grease-outlet hole; The steel ball that traditional grease pouring valve is equal and spring are to be all wholely set in valve body, because the spring force in valve body is fixed, cannot regulate the cracking pressure of grease pouring valve, and spring is after long-term use, elastic force can reduce gradually, cause spheroid cannot block greasing passage, so the phenomenon that causes seal gease to leak has certain room for improvement.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide and can regulates cracking pressure, and can also effectively prevent the band cap grease pouring valve that seal gease leaks.
For achieving the above object, the utility model provides following technological scheme: a kind of band cap grease pouring valve, comprise body, described body comprises bonnet, valve body, spheroid and spring, the first greasing passage that described bonnet two ends offer respectively fat hole and are communicated with fat hole, described spheroid and spring are all arranged in the first greasing passage, spool has also been threaded in described the first greasing passage, described spheroid one side seal gets lodged on fat hole and the other end is conflicted and is connected with spring, the opposite side of the corresponding spheroid of described spring is conflicted and is connected on spool, one end of the corresponding spring of described spool offers blind hole, on the side of described spool, also offer the through hole being communicated with blind hole, the second greasing passage that described valve body two ends offer respectively grease-outlet hole and are communicated with grease-outlet hole, one end of the corresponding spool of described bonnet is arranged in the second greasing passage and bonnet is threaded with the second greasing passage, on described spool, be provided with the sealed department for shutoff grease-outlet hole.
By adopting technique scheme, spheroid shutoff is on fat hole, and spring one end conflicts on spheroid, and the other end is conflicted on spool, spool is threaded in the first greasing passage, turn spool and just can change spool wear the degree of depth in the first greasing passage, when spool is screwed into the first greasing passage, spring is compressed, so it is large that the cracking pressure of setting becomes, when spool is back-outed the first greasing passage, spring unclamps, so the cracking pressure step-down of setting; Bonnet is threaded in valve body, and when bonnet is screwed into the second greasing passage, the sealed department on spool will block grease-outlet hole, and when bonnet is back-outed to the second greasing passage, the sealed department on spool will be separated with grease-outlet hole; Sealed department and spheroid all can prevent that seal gease from leaking, thereby play the effect of double seal; Body, when greasing, first turns spool, changes the compression degree of spring, thereby adjust the cracking pressure of body, and then the bonnet of back-outing, make the sealed department on spool separated with grease-outlet hole, then seal gease just can back down spheroid, from fat hole, enter the first greasing passage, from the first greasing passage, enter blind hole again, from blind hole, enter through hole, from through hole, enter the second greasing passage, from the second greasing passage, enter grease-outlet hole, from grease-outlet hole, enter equipment to be sealed; After body greasing, bonnet is screwed into the second greasing passage, make sealed department block grease-outlet hole, just can prevent that seal gease from flowing backwards; This design can regulate cracking pressure, and can also effectively prevent that seal gease from leaking.
The utility model is further set to: the bore of described the first greasing passage is greater than the bore of fat hole, the bore of described the second greasing passage is greater than the bore of grease-outlet hole, between described grease-outlet hole and the second greasing passage, be provided with the transition part that bore increases gradually, described transition part all with grease-outlet hole and the second greasing channel connection.
By adopting technique scheme, the bore of the first greasing passage is greater than the bore of fat hole, so spheroid can be filled in the first greasing passage, and the sphere of spheroid can block fat hole; The bore of the second greasing passage is greater than the bore of grease-outlet hole, thus spool can be arranged in the second greasing passage, and by sealed department shutoff on grease-outlet hole, and the bore of transition part is to increase gradually, thus make that sealed department and transition part fit tightr; This design can all be blocked fat hole and grease-outlet hole, thereby improves the sealing of body.
The utility model is further set to: described sealed department is conical.
By adopting technique scheme, because the bore of transition part increases gradually, and sealed department is conical, so transition part and sealed department adaptation just in time, sealed department can fit together more closely with transition part; This design improves the sealing between sealed department and grease-outlet hole.
The utility model is further set to: on described bonnet, be arranged with for turning the hexagon nut of bonnet, described hexagon nut and bonnet are wholely set.
By adopting technique scheme, hexagon nut is set on bonnet and with bonnet and is wholely set, hexagon nut can make bonnet more laborsaving when turning, by inner hexagon spanner, clamp hexagon nut, just can turn bonnet, and hexagon nut can increase the area of contact while turning, not only laborsaving but also can prevent that hexagon nut from damaging when turning; This design can conveniently turn bonnet.
The utility model is further set to: described spheroid is made by stainless steel.
By adopting technique scheme, spheroid gets rusty, and causes effectively blocking fat hole, thereby causes waste liquid to leak; Use stainless steel to manufacture spheroid, can effectively prevent that spheroid from getting rusty, and can also guarantee intensity and the resistance to pressure of spheroid; This design can improve the performance of spheroid.
