Specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, new to this practicality below in conjunction with accompanying drawing The embodiment of type is described in further detail.
This utility model embodiment provides a kind of air valve and keeps in repair clamping device, as depicted in figs. 1 and 2, the air valve maintenance Clamping device includes:
Chassis 3;
It is arranged on chassis 3 and at least two bolts 4 vertical with the upper plane on chassis 3, bolt 4 is evenly distributed on On same circumference;
Be threadedly coupled with bolt 4, for clamping the clamping plate 1 of air valve 8, the one end of clamping plate 1 towards the center of circle of the circumference Lower surface is used for contacting with the step surface of air valve 8, and clamping plate 1 is used for and air valve 8 towards the end face of the one end in the center of circle of the circumference Contacts side surfaces;
And, the retaining element 6 being fixedly connected with the lower plane on chassis 3.
The step surface of the vertical lower pressure valve 8 of the lower surface of the clamping plate 1 by being threadedly coupled with bolt 4, the medial extremity of clamping plate 1 Side of the face diameter to clamping air valve 8, realizes air valve maintenance fastening clamp of the clamping device to air valve 8, afterwards by fixing unit Part 6 is fixed on vice realizes that the entirety of maintenance clamping device and air valve 8 is fixed.Due to clamping device can fastening clamp with Fixed air valve 8 so that air valve maintenance operation is more convenient, more laborsaving.
Specifically, the shape and size on chassis 3 are not specifically limited, chassis 3 can be circular discs, square disk or Rectangular disk.More specifically, the chassis 3 of the air valve maintenance clamping device provided in the present embodiment is the circle that radius is 250mm Metal dish.
With regard to connected mode of the bolt 4 on chassis 3, specifically, air valve maintenance clamping device is additionally included in the upper of chassis 3 Plane arrange with 4 one-to-one groove 7 of bolt, and being radially arranged along chassis 3 of groove 7, bolt 4 is by groove 7 and chassis 3 Connection, and can move in groove 7.And groove 7 is uniformly distributed in the upper plane on chassis 3 with bolt 4.
The shape of groove 7 is not specifically limited, can be rectangle or oblong.
The species of groove 7 is not specifically limited, can be groove or caulking groove.
The number of groove 7 should be identical with the number of bolt 4, and at least two.
More specifically, groove 7 is rectangular through slot, the length and width respectively 100mm and 20mm of groove 7, and groove in the present embodiment 7 and the number of bolt 4 be four.
As groove 7 is used for connecting bolt 4 and limits moving direction of the bolt 4 in the upper plane on chassis 3, and this enforcement Example bracket groove 7 is rectangular through slot, and therefore matched bolt 4 adopts T-bolt, and the length in the T connector portion of bolt 4 is more than groove 7 width, the diameter of the screw rod of bolt 4 are less than or equal to the width of groove 7, and thus bolt 4 can pass through groove 7, and the length along groove 7 Move in direction.
And when groove 7 is caulking groove, the size of matched bolt 4 should also make corresponding change, the T of bolt 4 need to be met Type head can be achieved in bolt 4 and be connected in the upper plane on chassis 3 and the movement along 7 length direction of groove in embedded groove 7.
By the inner face of the clamping plate 1 being threadedly coupled with bolt 4 along 7 slide bolt 4 of groove, can be caused to air valve 8 Side applies radial pressure, and groove 7 and bolt 4 being uniformly distributed on chassis 3, it is ensured that the firm clamping air valve 8 of clamping plate 1. Due to arriving the distance of 8 side of air valve with regulating bolt 4, the therefore air valve maintenance clamping device provided by the present embodiment is applied to The air valve of sizes.
With regard to clamping plate 1, specifically, clamping plate 1 is the rectangular slab for being provided with tapped through hole, and by tapped through hole, clamping plate 1 can be with Bolt 4 is threadedly coupled.And the top of clamping plate 1 is provided with fixing nut 5, fixing nut 5 screws in bolt 4, limits clamping plate 1 and exist Away from the motion on 3 direction of chassis.In order that clamping plate 1 can be connect by the clamping air valve 8 that clamping plate 1 more can be consolidated with air valve 8 Tactile end face is processed into the arc surface of the indent being engaged with 8 surface of air valve.
Rectangle cushion block 2 is provided between clamping plate 1 and chassis 3 simultaneously.
By screwing clamping plate 1 along bolt 4, the lower plane of clamping plate 1 can be caused to apply vertical pressure to the step surface of air valve 8 Power, while in order to ensure firm pressure holding of the clamping plate 1 to air valve 8, arrange cushion block 2, in the upper of clamping plate 1 between clamping plate 1 and chassis 3 Side arranges fixing nut 5.In the air valve maintenance clamping device provided using the present embodiment, pad on the lower section pad of clamping plate 1 Block 2, be tightened nut 5 afterwards, enables clamping plate 1 to apply enough lateral pressures to the step surface of air valve 8 and is pressed in air valve 8 In the upper plane on chassis 3.And in order that the air valve maintenance clamping device provided by the present embodiment is applied to various sizes of gas Valve, the thickness of cushion block 2 have plurality of specifications, more specifically, the thickness of cushion block 2 can be 2mm, 5mm, 10mm, 18mm etc..Use When can according to the height of the step of air valve 8 select suitable thickness cushion block 2.
There can also be various ways with regard to retaining element 6, need using corresponding fixation side for different retaining elements 6 Formula.Specifically, the retaining element 6 for for example keeping in repair clamping device in the air valve provided by the present embodiment is to be welded under chassis 3 The fixed block of surface circle centre position, more specifically, retaining element 6 is length of side 60mm, the square block of high 30mm in the present embodiment.Use During the air valve maintenance clamping device provided by the present embodiment, after clamping device anchorage clip handles air valve, need to be vised using vice Retaining element 6 is so as to keeping in repair clamping device by air valve and air valve 8 is overall fixed.
Keep in repair the clamping action of the lower plane to the step surface of air valve of the clamping plate of clamping device by air valve, and clamping plate Clamping action of the inner face to air valve side so that air valve maintenance clamping device tightly clamps air valve.Then again air valve is tieed up The retaining element for repairing clamping device bottom is fixed on vice, it is achieved that the clamping and fixation of air valve.Treat that air valve is new with this practicality The clamping device that type embodiment is provided reuses, after being fixed on vice, the locking nut that spanner screws off air valve.Air valve maintenance folder The instrument of holding causes air valve maintenance operation more easy, improves air valve maintenance work efficiency, while reducing in operation The probability that damages is caused to air valve.
Preferred embodiment of the present utility model is the foregoing is only, not in order to limit this utility model, all in this practicality Within new spirit and principle, any modification, equivalent substitution and improvements that is made etc. should be included in guarantor of the present utility model Within the scope of shield.
