Description

Technical Field

[0001] The utility model relates to a flange ball valve, in particular to a manual-automatic integrated flange ball valve. Background Art

[0002] At present, ball valves have the advantages of simple structure, good sealing and low flow resistance, so they are widely used in the control of various fluids in the petroleum, chemical, metallurgy, electric power and other industries; however, traditional ball valves usually adopt a separate manual operation or a separate automatic control method. In some complex industrial environments, a single operation method is difficult to meet the diverse usage requirements. In order to solve the above defects, valve manufacturers have developed manual-automatic ball valves, such as the disclosed Chinese patent number 201920373986.5, named "A manual-automatic integrated ball valve", which is a ball valve structure that integrates a manual drive part and an automatic drive part. However, this integrated structure is just a simple combination of two ball valves with different drive modes. In actual use, there are defects such as complex structure, inconvenient installation, and many connection nodes that affect the sealing performance. In addition, the manual drive part and the automatic drive part are set on the same horizontal plane, and it is easy for manual and automatic operations to interfere with each other, and the reliability of use is poor. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a manual-automatic integrated flange ball valve with compact structure, convenient installation, good sealing performance and reliable use.

[0004] The technical problem of the utility model is achieved through the following technical solutions:

[0005] A manual-automatic flange ball valve comprises a valve body, a manual ball valve core and an automatic ball valve core inside the valve body, and a manual drive component and an automatic drive component outside the valve body. The manual drive component drives the rotation and opening and closing of the manual ball valve core, and the automatic drive component drives the rotation and opening and closing of the automatic ball valve core. The manual ball valve core and the automatic ball valve core are respectively installed in the two ends of the valve body, and the rotation axis of the manual ball valve core and the rotation axis of the automatic ball valve core are perpendicular to each other, and the manual drive component and the automatic drive component outside the valve body are staggered by 90°.

[0006] A front flange and a rear flange are respectively installed at both ends of the valve body, and a manual valve core cavity for rotating and sealing the manual ball valve core is formed between the front flange and the front end of the valve body, and an automatic valve core cavity for rotating and sealing the automatic ball valve core is formed between the rear flange and the rear end of the valve body.

[0007] A front valve seat is provided in the manual valve core cavity, and the manual ball valve core is installed in the front valve seat to form a rotating seal; a rear valve seat is provided in the automatic valve core cavity, and the automatic ball valve core is installed in the rear valve seat to form a rotating seal.

[0008] Sealing gaskets are provided between the front flange and the front end of the valve body, and between the rear flange and the rear end of the valve body.

[0009] The manual drive member is a handle or a handwheel, which drives the manual ball valve core to rotate and open and close through the valve stem; the automatic drive member is an electric actuator or a pneumatic actuator, which drives the automatic ball valve core to rotate and open and close through the valve stem.

[0010] A manual installation platform is provided on the valve body, and a flange platform for installing the manual drive component is provided on the manual installation platform.

[0011] A limiting convex and a limiting column constituting the rotation limiting of the manual driving member are respectively provided between the manual driving member and the flange platform.

[0012] An automatic installation platform for installing the automatic driving component is provided outside the valve body.

[0013] The front valve seat and the rear valve seat are both made of PTFE sealing material or PPL sealing material.

[0014] Compared with the prior art, the present invention mainly installs the manual ball valve core and the automatic ball valve core in the two ends of the valve body respectively, that is, the manual ball valve core and the automatic ball valve core share a valve body, thereby ensuring the compactness of the overall structure after integration, facilitating installation, and reducing connection nodes to enhance sealing performance; at the same time, the rotation axis of the manual ball valve core and the rotation axis of the automatic ball valve core are perpendicular to each other, so that the manual drive part and the automatic drive part outside the valve body form a 90° staggered arrangement; therefore, through this staggered design to avoid the manual drive part and the automatic drive part being on the same horizontal plane, it can better avoid mutual interference between manual and automatic operations and improve reliability of use.

[0021] Manual and automatic flange ball valve, such as Figure 1 、 Figure 3 As shown, it is a combination ball valve that meets the needs of different working conditions through manual and automatic operation. Its structure mainly includes a valve body 1, a manual ball valve core 2 and an automatic ball valve core 3 in the valve body, and a manual drive part and an automatic drive part 11 outside the valve body.

[0022] The valve body 1 can be spherical or cylindrical in shape, and a fluid channel is provided inside the valve body. The fluid channel passes through both ends of the valve body 1, and a front flange 4 and a rear flange 5 are fixedly installed at both ends of the valve body by bolts. Figure 1 、 Figure 3 The left side of the view shown is the front side, and the right side of the view is the rear side. Sealing gaskets 15 are provided between the front flange 4 and the front end of the valve body 1, and between the rear flange 5 and the rear end of the valve body 1 to form a connection seal.

[0023] The manual ball valve core 2 and the automatic ball valve core 3 are respectively installed in the two ends of the valve body 1, that is, the manual ball valve core 2 and the automatic ball valve core 3 share a valve body 1. The specific structure is: a manual valve core cavity 10 is formed between the front flange 4 and the front end of the valve body 1, and a front valve seat 8 is provided in the manual valve core cavity. The manual ball valve core 2 can be installed in the front valve seat 8 to form a rotating seal; an automatic valve core cavity 13 is formed between the rear flange 5 and the rear end of the valve body 1. A rear valve seat 12 is provided in the automatic valve core cavity. The automatic ball valve core 3 can be installed in the rear valve seat 12 to form a rotating seal.
