Description

A supplementary mounting tool for installing FBV ball valve connects

Technical Field

The utility model relates to an auxiliary installation tool especially relates to an auxiliary installation tool for installing FBV ball valve connects.

Background

The FBV ball valve is a special ball valve, and has the characteristics of large volume (DN32/75 and the like), irregular appearance (octagonal drum shape), thinner screwed joint of a joint and the like, as shown in figure 1, the torque for screwing the joint according to different valve types is 500-800 N.m, so that the fixation is very difficult when the screwed joints at two ends are assembled, and if opposite-side clamping is adopted, the valve body is deformed or damaged due to the thin wall.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an auxiliary mounting tool for installing FBV ball valve joint in order to overcome the defect that above-mentioned prior art exists.

The purpose of the utility model can be realized through the following technical scheme:

an auxiliary mounting tool for mounting an FBV ball valve joint comprises a pair of auxiliary clamping pieces which assist in clamping an FBV ball valve on a bench vice, wherein the auxiliary clamping pieces are steel plates with inner octagonal holes.

Furthermore, the outer contour of the inner octagonal hole steel plate is rectangular.

Furthermore, the section shape of the inner hole of the steel plate with the inner octagonal hole is regular octagon.

Furthermore, the size of the inner hole of the inner octagonal hole steel plate is matched with the shape of the cross section of the valve body of the FBV ball valve.

Furthermore, the inner wall surface of the inner octagonal hole steel plate is a conical surface.

Furthermore, the shape of the hole of the inner octagonal hole steel plate is matched with the shape of the valve body, the shape of the valve body is octagonal, the side length is gradually increased from the outer side to the inner side, the inner octagonal hole steel plate can clamp the valve body, and the valve body is prevented from sliding in the auxiliary clamping piece.

When the ball valve is used, the pair of auxiliary clamping pieces are respectively sleeved at two ends of the FBV ball valve body, the valve body is fixed and does not rotate, then the valve body and the auxiliary clamping pieces are fixed on a bench vice, and two sides of the auxiliary clamping pieces are clamped, so that the valve body is prevented from being directly contacted with the valve body to damage, and after the fixing is completed, the connector is assembled on the valve body by using a hexagonal wrench.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the application range is wide: various valve bodies and joints with different specifications of the FBV ball valve can be assembled by using the tool;

2. the operation is convenient: the valve body can be assembled without other special tools only by the common bench vice, and the valve body is safe and reliable, so that the valve body is prevented from being damaged due to the fact that the bench vice directly clamps the valve body;

3. the cost is low: the device is simple, convenient to operate and free of redundant auxiliary tools.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Examples

An auxiliary mounting tool for mounting an FBV ball joint comprises a pair of auxiliary clamping pieces 3 (figure 2) for assisting in clamping an FBV ball joint on a bench vice 4, wherein the auxiliary clamping pieces 3 are steel plates with inner octagonal holes. The outer contour of the inner octagonal hole steel plate is rectangular. The section shape of the inner hole of the inner octagonal hole steel plate is regular octagon. The hole inner wall of interior eight corner hole steel sheet personally submits the conical surface, and the shape in the hole of interior eight corner hole steel sheet and the shape phase-match of valve body 1 can block valve body 1, avoids valve body 1 to slide in auxiliary clamping piece 3.

As shown in figure 3, when using, with a pair of auxiliary clamping piece 3 suit respectively at FBV ball valve body 1 both ends, fixed valve body 1 does not rotate, then is fixed in the bench vice 4 with valve body 1 and auxiliary clamping piece 3 on, grasps the both sides of auxiliary clamping piece 3 to avoid direct and valve body 1 to contact and damage valve body 1, after fixed, utilize the hexagonal spanner to assemble on valve body 1 with connecting 2.

The embodiments described above are intended to facilitate the understanding and use of the invention by those skilled in the art. It will be readily apparent to those skilled in the art that various modifications to these embodiments may be made, and the generic principles described herein may be applied to other embodiments without the use of the inventive faculty. Therefore, the present invention is not limited to the above embodiments, and those skilled in the art should make improvements and modifications within the scope of the present invention according to the disclosure of the present invention.
