Background technology
Butterfly valve is used on the pipeline of pneumatic conveying cement, controls the conveying of powder in pipeline by spool and changes the conveying direction of powder.Owing to the solid particles such as the long-term work with pressure of butterfly valve and cement constantly wear and tear, O-ring seal is easily damaged, and need to often change；The key link wherein dismantling cushion rubber is to take out the valve plate bearing pin of location spool.
The valve plate bearing pin taking out location spool at present mainly uses two kinds of methods: one is to stretch into valve plate bearing pin axle journal with screwdriver, is little by little prized；Another kind of method is to be destroyed by O-ring seal, is inserted into end part of pin shaft with screwdriver and is prized.But, when above two method is owing to dismantling, operating space is little, does not has specific purpose tool, and dismounting is laborious, and the longest, efficiency is low, is easily damaged other part, and changing O-ring seal becomes maintenance personal's one of hard work；Accordingly, it would be desirable to a kind of simple in construction of exploitation, dismounting is quick, safe and reliable, can alleviate labor strength, and the valve plate bearing pin significantly improving operating efficiency takes out specific purpose tool.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction, safe and reliable, it is possible to take out the butterfly valve bearing pin drawbench of valve plate bearing pin rapidly.
To this end, technical solutions of the utility model are as follows:
A kind of butterfly valve bearing pin drawbench, including screw rod, square sleeve and tightening nut；Wherein:
Screw rod includes stock portion and is arranged on the tight lock part of bottom, stock portion；Offer a U-shaped groove connected with tight lock part side sidewall along tight lock part bottom surface, and groove upper inner diameter is more than lower inner diameter；Wherein, groove upper inner diameter adapts with the external diameter of butterfly valve bearing pin top bearing pin cap, groove lower inner diameter and butterfly valve pin body external diameter adapt and are less than the external diameter of bearing pin cap, implement axial force lifting bearing pin will not be made to depart from tight lock part after making tight lock part radially insert groove；Wherein, the bend of U-shaped groove has identical radius of curvature with bearing pin cap and pin body；
Square sleeve is the square cylinder of a bottom opening, is provided with a through hole adapted with screw rod stock portion external diameter in square sleeve end face center, makes screw rod be sleeved on from bottom to top in square sleeve and make stock portion pass the through hole on square sleeve end face；Stock portion outer wall is provided with connection external screw thread, and tightening nut is installed on outside stock portion and is arranged on above square sleeve；Square sleeve supports, by screw rod force dispersion during drawing bearing pin in butterfly valve housing for forming locking nut.
The internal diameter of square sleeve adapts with the external diameter of screw rod tight lock part；The internal height of square sleeve is more than or equal to tight lock part height and the total length sum of bearing pin.
Compared with prior art, this butterfly valve bearing pin drawbench simple in construction, utilize lever principle to be designed, by the cooperation between tight lock part, square sleeve and tightening nut, bearing pin is pulled out, easy to use, dismounting is quick, safe and reliable time saving and energy saving, not damages parts.

Detailed description of the invention
Below in conjunction with the accompanying drawings and the utility model is described further by specific embodiment, but following embodiment has absolutely not any restriction to the utility model.
As shown in Figure 3 and Figure 4, butterfly valve includes valve plate 6, O-ring seal 7 and the butterfly valve shell 4 that from-inner-to-outer is set with successively, and the right-hand member outer wall of butterfly valve shell 4 is formed with a flange, and flange top surface is a plane, wherein, described valve plate bearing pin 5 includes cylinder body and is arranged on the bearing pin cap on top；The friction tight insertion of the valve plate bearing pin 5 through hole from flange top surface center, and by the through hole on O-ring seal 7 and valve plate 6 to butterfly valve inside, make each parts be formed as an entirety；Butterfly valve bearing pin drawbench is designed by the design feature that flange top surface therefore can be utilized to be a plane and both bearing pin caps of being positioned at bearing pin top.
As it is shown in figure 1, this butterfly valve bearing pin drawbench includes screw rod 1, square sleeve 2 and tightening nut 3；
Screw rod 1 includes stock portion 11 and is arranged on the tight lock part 12 of bottom, stock portion 11；Offer a groove connected with tight lock part 12 side sidewall along tight lock part 12 bottom surface, and groove upper inner diameter is more than lower inner diameter；Specifically, groove upper inner diameter is identical with the external diameter of butterfly valve bearing pin top bearing pin cap, and groove lower inner diameter is identical with butterfly valve pin body external diameter but is less than the external diameter of bearing pin cap, and the bend of U-shaped groove has identical radius of curvature with bearing pin cap and pin body；
Square sleeve 2 is the steel square cylinder of a bottom opening, a through hole adapted with screw rod 1 stock portion 11 external diameter it is provided with, in making screw rod 1 be sleeved on square sleeve 2 from bottom to top and make stock portion 11 pass the through hole on square sleeve 2 end face in square sleeve 2 end face center；Stock portion 11 outer wall is provided with connection external screw thread, and tightening nut 3 is installed on outside stock portion 11 and is arranged on above square sleeve 2；The square sleeve 2 of described butterfly valve bearing pin drawbench is sitting in when drawing on the flange fore-and-aft plane of described butterfly valve shell 4 and forms described square sleeve 2 and supports.
Wherein, tight lock part 12 is square structure, stock portion 11 arranges and is fixed on this square structure end face center, tight lock part 12 external diameter is slightly larger than the internal diameter of square sleeve 2, and the interior height of square sleeve is consistent with the total length sum of the height of tight lock part 12 and bearing pin, it is ensured that bearing pin all can pull out in pin shaft hole.
The using method of this butterfly valve bearing pin drawbench is as follows:
As shown in Figure 1, the tightening nut 3 of butterfly valve bearing pin drawbench is screwed out from screw rod 1, screw rod 1 is made to separate with square sleeve 2, and tight lock part 12 is radially inserted butterfly valve bearing pin neck, the tight lock part 12 of screw rod 1 radially will be inserted into bearing pin top end, fully-inserted U-shaped groove the inner, make bearing pin enter the U-shaped groove crooked position with it with same curvature radius；
Then screw rod 1 is sleeved in square sleeve 2 from bottom to top, and makes stock portion 11 stretch out outside square sleeve 2, again tightening nut 3 is arranged on the stock portion 11 of screw rod 1, is completed butterfly valve bearing pin drawbench；When drawing butterfly valve bearing pin 5, as shown in figs. 34, rotating tightening nut 3 makes square sleeve 2 bottom supporting in butterfly valve shell 4 top planes, continuing precession locking nut makes the tight lock part 12 of screw rod 1 be axially moveable in square sleeve 2, realize screw rod 1 by nut precession (going out) on screw rod to move axially in sleeve, and bearing pin is pulled out；After changing butterfly valve seal circle, by bearing pin 5 according to installing in situ, i.e. complete the replacing of butterfly valve seal circle, can be continuing with.
