Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example 1: a regulating valve with compact structure for a burner is disclosed, as shown in figures 1 to 3, and comprises a valve body 1, a rotating shaft 2 rotatably connected with the valve body 1 and a valve plate 3 fixed on the rotating shaft 2, wherein the valve plate 3 rotates to control the flow of the regulating valve. Four flange holes are formed in the valve body 1 and used for installing the adjusting valve. The protruding sealed boss 11 that is used for conflicting with the mounted position structure of valve body 1 both sides around the valve body 1, sealed boss 11 surface has sealed waterline, improves the leakproofness of governing valve connection face. And a deep groove ball rotating bearing 6 is fixed between the rotating shaft 2 and the valve body 1 and used for reducing friction. Offer the installation breach of in-band screw thread on the rotation axis 2, offer on the valve plate 3 just to the counter sink 5 of installation breach, the bolt is worn to be equipped with in counter sink 5 department, the top of bolt have with installation breach threaded connection's external screw thread, the recess department on the rotation axis 2 is fixed in valve plate 3 to the bolt. A sealing ring 7 is arranged between the gap between the valve body 1 and the rotating shaft 2, so that gas in the regulating valve is prevented from leaking from the gap between the rotating shaft 2 and the valve body 1.

When the regulating valve is processed, the sealing ring 7 is fixed in the valve body 1, the rotating bearing 6 is fixed in the valve body 1, and then the rotating shaft 2 is inserted into the valve body 1 to be matched with the rotating bearing 6.
