[0017] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and not to limit the present application.
[0018] A compact combined valve, as shown in Figures 1-4 , comprises a valve body 1, a first plug 2, a second plug 3 and a valve cover 4, the valve body 1 is provided with a first plug cavity 11 and a second plug cavity 12, the valve body 1 is axially provided with a through flow passage 13, and the flow passage 13 communicates with the first plug cavity 11 and the second plug cavity 12, the first plug 2 and the second plug 3 are rotationally arranged in the first plug cavity 11 and the second plug cavity 12, and the valve cover 4 is arranged at the opening of the first plug cavity 11 and the second plug cavity 12. The first plug 2 and the second plug 3 are sealingly arranged in the valve body 1. By arranging the first plug 2 and the second plug 3 in series, according to the opening state and the adjusting characteristics of the first plug 2 and the second plug 3, the complex flow requirements can be achieved by superposition. Moreover, the two plugs are integrated in one valve body 1, which can reduce the volume of the series valve.
[0019] In an embodiment, as shown in Figures 1-4 , the openings of the first plug cavity 11 and the second plug cavity 12 are arranged on opposite sides of the valve body 1. The plug needs to be driven by a hand wheel or an actuator to control the opening of the plug; by arranging the openings on opposite sides of the valve body 1, i.e. the valve stems of the first plug 2 and the second plug 3 are directed to the two sides of the valve body 1, so that there is enough space to install the actuator; in addition, the volume of the combined valve can be reduced.
[0020] In an embodiment, as shown in Figures 1-4 , a first valve port 21 is arranged on the first plug 2, and the first valve port 21 is triangular.
[0021] In an embodiment, asFigures 1-4 As shown in the figure, the second valve port 31 is arranged on the second plug 3, and the second valve port 31 is rectangular. By arranging the two plugs with the triangular and rectangular valve ports in series combination, according to the switch angle combination of the first plug 2 and the second plug 3, some relatively complex flow conditions are realized by superposition and cooperation, and the needs of customers are met.
[0022] In an embodiment, as shown in the figure, Figures 1-4 As shown in the figure, the bypass flow channel 14 is arranged on the valve body 1, and the bypass flow channel 14 is located between the first plug cavity 11 and the second plug cavity 12. The arrangement of the bypass flow channel 14 can be connected with other valves or pipeline devices. For example, the flow channel 13 of the valve body 1 has two input ends, the input flow is adjusted by the first plug 2 and the second plug 3, and the mixed output is realized by the bypass flow channel 13. In addition, the bypass flow channel 14 can be connected with a gas source to realize the purging of the pipeline. Of course, when the bypass flow channel 14 is not used, it can be plugged by a plug.
[0023] In an embodiment, as shown in the figure, Figures 1-4 As shown in the figure, the flange plate is arranged on the bypass flow channel 14. The bypass flow channel 14 is convenient to connect with other valves or pipeline devices.
[0024] The above is only a preferred embodiment of the present application, and is not used to limit the implementation range of the present application; if the present application is modified or replaced without departing from the spirit and scope of the present application, all should be covered in the protection range of the present application claim.
