Description

Technical Field

[0001] The utility model relates to the field of regulating valves, in particular to a single-seat regulating valve with a guide valve cover. Background Art

[0002] Existing single-seat regulating valves consist of a valve body, sealing gasket, guide, bonnet, and bracket. In some narrow working conditions, where valve height is limited, existing single-seat regulating valves may be difficult or even impossible to install. To address these special working conditions, a single-seat regulating valve with a guide bonnet has been designed. Summary of the Invention

[0003] In order to reduce the height of the valve, the utility model provides a single-seat regulating valve with a guide valve cover. The original guide member is thickened and a guide hole is provided so that it has both the guide and valve cover functions, namely the guide valve cover. Placing it in the valve body reduces the overall weight and height of the valve, and can meet the working conditions of narrow spaces.

[0004] The technical solution adopted by the utility model is: a single-seat regulating valve with a guide valve cover, comprising a valve body, a valve stem, a guide valve cover, a bracket and a packing, wherein the guide valve cover is arranged in the valve body, the valve stem is arranged in the center of the guide valve cover, the bracket is arranged on the guide valve cover, a guide hole is arranged at the lower part of the guide valve cover, and the packing is filled in the guide hole.

[0005] In the above technical solution, a sealing gasket is provided at the connection between the guide valve cover and the valve body.

[0006] The beneficial effect of the utility model is that the guide member and the valve cover are converted into one part, the guide valve cover, through improvement, and placed in the valve body, thereby reducing the weight and height of the entire valve and meeting the working conditions of narrow spaces.

[0009] In the figure: 1. Valve body; 2. Valve stem; 3. Sealing gasket; 4. Guide valve cover; 4-1. Guide hole; 5. Bracket; 6. Packing; 7. Bolt; 8. Nut. DETAILED DESCRIPTION

[0010] The present invention will be further described below with reference to the accompanying drawings.

[0011] like Figure 1 、 Figure 2As shown, a single-seat regulating valve with a guide valve cover includes a valve body 1, a valve stem 2, a sealing gasket 3, a guide valve cover 4, a bracket 5 and a packing 6. A guide hole 4-1 is provided at the lower part of the guide valve cover 4. The valve stem is inserted into the middle of the guide valve cover 4. The packing 6 is filled in the guide hole 4-1 to prevent the valve stem 2 from swinging left and right. The sealing gasket 3 is placed on the step of the flange in the valve body 1. The guide valve cover 4 is placed into the valve body 1. The guide valve cover 3 presses the sealing gasket 2. The bracket 5 is placed on the guide valve cover 4 and pressed. Finally, the bracket 5 and the valve body 1 are connected with bolts 7 and nuts 8. By converting the guide part and the valve cover into one part - the guide valve cover 4 through improvement, and placing it in the valve body 1, the weight and height of the entire valve are reduced, which can meet the working conditions of narrow spaces.
