SUMMERY OF THE UTILITY MODEL

An object of the utility model is to design a valve gap fastening jig, solved the sealed face leakage problem of valve gap.

The technical scheme of the utility model is that:

the valve bonnet fastening clamp comprises a clamp body, wherein the clamp body is in a long-strip oval shape, different shapes can be designed according to different valve appearances, the clamp body comprises two symmetrical half clamps, two end parts of each half clamp are provided with threaded holes, and the clamp is mainly used for effectively fixing the clamp on a valve needing the clamp through bolts; the valve bonnet clamp is characterized in that an M24 threaded hole is machined in one side end face of the clamp body, the function of a jackscrew is mainly used, bolts of certain specifications and models are used as the jackscrew and are jacked on the protruding face of a valve bonnet fastening bolt, external jacking force is used for avoiding looseness of the valve bonnet bolt caused by vibration, the position and the number of the M24 threaded hole are consistent with those of screw holes in a valve bonnet flange, and the M24 jackscrew is installed in the M24 threaded hole.

The clamp is designed to apply a tightening force to a specific valve according to the external dimension of the valve, so that the problem that the bolt of the valve cover of the valve is broken due to vibration to cause accidents is avoided.

The clamp body adopts a split butt clamp type, is clamped through a connecting lug plate in the horizontal direction and is fastened through a jackscrew in the vertical direction, and is fixed by fastening bolts after being fixed at the protruding part of the median plane of the valve cover because the clamp is designed according to the overall dimension of a specific valve.

After the installation on site, all jackscrews are fastened well, and a good fastening effect is guaranteed to be achieved.

The outer edge of the valve cover flange is arc-shaped, and the outline shape of the clamp is designed according to the shape of the valve cover connecting flange according to the shape characteristics of the valve cover connecting flange.

The clamp body is manufactured in batches by adopting a mould, and the material is cast steel.

The utility model has the advantages that: the leakage stoppage device has the advantages that the problem that the leakage accident is caused by the failure of the bolt of the sealing surface of the valve cover due to vibration of the valve is avoided, the leakage stoppage device is suitable for the leakage stoppage treatment of the valve cover on a production site, the online treatment of leakage points is realized, and the continuous operation of a production device is guaranteed without stopping.

The present invention will be further explained with reference to the drawings and examples.

Drawings

Fig. 1 is a top view of a fastening clamp for a valve cover of a valve according to an embodiment of the present invention;

fig. 2 is a side view of the utility model discloses a be used for valve gap fastening jig.

Detailed Description

The following description of the preferred embodiments of the present invention is provided for the purpose of illustration and description, and is not intended to limit the invention.

Example 1

As shown in fig. 1-2, a valve cover fastening jig is designed to give a fastening force to a valve from the outside according to the external dimensions of a specific valve, thereby preventing the bolt of the valve cover from being broken due to vibration to cause accidents. The anchor clamps body is rectangular ellipse (can be according to the different shape of valve appearance design of difference), anchor clamps body 1 includes two parts half anchor clamps 11 of symmetry, every part both ends of half anchor clamps 11 all are equipped with screw hole 2, and the main function is with the effectual valve of fixing anchor clamps on the needs anchor clamps of bolt. Processing M24 screw hole 3 on the 1 side end face of anchor clamps body, the main effect is the effect of jackscrew, regards the bolt of certain specification model as the jackscrew, and the top is on valve gap fastening bolt's the outstanding face, with outside jacking force, avoids arousing the valve gap bolt because of the vibration not hard up, and the position and the quantity of M24 screw hole 3 are unanimous with the screw on the valve gap flange, M24 jackscrew is installed to M24 screw hole 3.

The clamp body 1 adopts a split butt clamp type, is clamped by the connecting lug plate 4 in the horizontal direction and is fastened by the jackscrew in the vertical direction, and is fixed by the fastening bolt after being fixed at the protruding part of the middle split surface of the valve cover because the clamp is designed according to the external dimension of a specific valve.

After the installation on site, all jackscrews are fastened well, and a good fastening effect is guaranteed to be achieved.

The outer edge of the flange of the valve cover is arc-shaped, and the outline shape of the clamp is designed according to the shape of the flange of the valve cover according to the shape characteristics of the flange of the valve cover.

The clamp body is manufactured in batches by adopting a mould, and the material is cast steel.
