Description

Technical Field

[0001] This utility model relates to the field of ball valve operation technology, and in particular to a ball valve with a handle seat that is easy to operate. Background Technology

[0002] Currently, ball valves are widely used in various industrial pipelines as a common fluid control device. When the valve and the operating position are far apart, lengthening the entire valve increases costs and requires consideration of a larger installation and operating space during design, resulting in a bulky and cumbersome design. However, without lengthening the valve, normal operation is impossible. Therefore, in certain specific scenarios, we need to use an extended operating device to operate the ball valve more flexibly.

[0003] To address these issues, we developed a ball valve with an easy-to-operate handle. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a ball valve with an easy-to-operate handle seat, which has the advantages of improved flexibility, safety, efficiency and easy maintenance.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a ball valve with an easy-to-operate handle seat, comprising a handle seat, a first valve stem fixedly connected to the bottom end of the handle seat, a second valve stem inserted into the bottom end of the first valve stem and fixedly connected to the second valve stem, a valve body sealed and connected to the middle position of the second valve stem, and a ball inserted into the bottom end of the second valve stem, and a connecting body sealed and connected to one end of the valve body.

[0006] Preferably, the valve body, the connecting body, and the ball are pressed together by a valve seat, and a handle is fixedly connected to the top of the handle seat.

[0007] Preferably, the handle base is provided with a base, a connector and a plug from bottom to top, and the two ends of the connector are fixedly connected to the base and the plug respectively.

[0008] Preferably, the base has a first groove at its bottom end and the first valve stem has a flat surface at its top end, and the flat surface is fixedly connected to the first groove by screws.

[0009] Preferably, a second groove is provided at the top of the base, and the bottom end of the connector is fixedly connected to the second groove.

[0010] Preferably, the bottom end of the plug-in is provided with a recessed groove, which is fixedly connected to the top end of the connector.

[0011] Preferably, the connector has a plug hole and a positioning hole, the plug hole is plugged into the handle, and the positioning hole is fixedly connected to the handle by bolts.

[0012] Preferably, a first screw hole is provided at the bottom end of the side wall of the first valve stem, and a second screw hole is provided at the top end of the side wall of the second valve stem. The first screw hole and the second screw hole are fixedly connected by a set screw.

[0013] Preferably, a connecting piece is fixedly connected to the bottom of the side wall of the base, and a cover is pressed onto the top of the valve body. The connecting piece and the cover are connected by a pin with holes.

[0014] Preferably, the second valve stem is provided with multiple V-rings, and the top of the valve body is press-fitted to the V-rings by a pressure cap.

[0015] Preferably, the second valve stem is further provided with multiple sealing gaskets and has a shoulder, wherein the sealing gaskets are pressed between the shoulder and the valve body.

[0016] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0018] Figure 1 This is a schematic diagram of the ball valve with an easy-to-operate handle seat as described in this utility model. Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] Figure 1A ball valve with an easy-to-operate handle seat includes a handle seat 30. A first valve stem 11 is fixedly connected to the bottom end of the handle seat 30. A second valve stem 12 is inserted into and fixedly connected to the bottom end of the first valve stem 11. The valve stem has a split structure, consisting of the first valve stem 11 and the second valve stem 12 inserted and locked together. A valve body 90 is sealed to the middle position of the second valve stem 12, and a ball 100 is inserted into its bottom end. A connecting body 95 is sealed to one end of the valve body 90, and the connecting body 95 is sealed to the valve body 90. The valve body 90, the connecting body 95, and the ball 100 are pressed together by a valve seat 80. A handle 40 is fixedly connected to the top end of the handle seat 30. Rotating the handle 40 rotates the valve stem through the handle seat 30, thereby rotating the ball. Rotating the handle 40 opens and closes the valve.

[0021] The handle base 30, from bottom to top, comprises a base 31, a connector 32, and a plug-in 33. Both ends of the connector 32 are fixedly connected to the base 31 and the plug-in 33 respectively, first inserted and then welded. Due to space limitations or safety considerations, the connector 32 is long, facilitating flexible operation of the ball valve. The base 31 has a first groove 311 at its bottom and a second groove 310 at its top. The top of the first valve stem 11 has a flat surface 111, which is fixedly connected to the first groove 311 by screws 20. The bottom end of the connector 32 is fixedly connected to the second groove 310. The bottom end of the plug-in 33 has a recess 330, and the plug-in 33 has an insertion hole 331 and a positioning hole 332. The recess 330 is fixedly connected to the top end of the connector 32. The insertion hole 331 is inserted into the handle 40, and the positioning hole 332 is fixedly connected to the handle 40 by bolts 50. The handle 40 is a steel pipe, perpendicular to the valve stem, and its direction aligns with the flow path direction when the ball is open. A connecting piece 34 is fixedly connected to the bottom side wall of the base 31, and a cover 36 is pressed onto the top of the valve body 90. The connecting piece 34 and the cover 36 are connected by a perforated pin 35. The perforated pin allows the cover and the handle seat to rotate simultaneously.

[0022] A first screw hole 115 is provided at the bottom end of the side wall of the first valve stem 11, and a second screw hole 125 is provided at the top end of the side wall of the second valve stem 12. The first screw hole 115 and the second screw hole 125 are fixedly connected by a set screw 13, which integrates the split valve stems into one unit. The split structure facilitates processing and assembly. Multiple V-rings 60 and multiple sealing gaskets 70 are passed through the second valve stem 12, and a shoulder 121 is provided. The shoulder 121 facilitates crimp sealing and prevents liquid in the ball chamber from leaking out through the valve stem. The top end of the valve body 90 is crimped with a V-ring 60 through a gland 91. A sealing gasket 70 is crimped between the shoulder 121 and the valve body 90. The double seal of the sealing gasket and V-ring improves the sealing performance of the valve stem.

[0023] The handle seat uses an extended operating device. The bottom is used to connect to the valve stem of the main valve, and the top is used to install the steel pipe handle for switching, thereby realizing the opening and closing operation of the bottom valve. The top is designed with bolt connections to tighten the handle seat and the steel pipe handle, making the assembly more secure and reliable. The bottom is designed with screws to tighten the valve stem and the handle seat to realize valve actuation. The simplified design of the handle seat makes it easier to process and manufacture. Compared with lengthening the entire valve or the valve stem, it reduces costs and facilitates maintenance.

[0024] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
