Example 1:

the control valve for loading and unloading gas field water as shown in figure 1 comprises an upper valve body 1 and a lower valve body 6 which are detachably connected and keep the inside communicated, wherein the upper valve body 1 and the lower valve body 6 are respectively provided with a female joint 4 and a male joint 5 which are communicated with the outside, and a first piston 2 and a second piston 7 which are used for controlling the opening and closing of the female joint 4 and the male joint 5 are respectively arranged in the upper valve body 1 and the lower valve body 6.

The working principle is as follows:

the control valve in this embodiment includes two parts, namely, an upper valve body 1 and a lower valve body 6, the upper valve body 1 and the lower valve body 6 are connected with each other and respectively have a female connector 4 and a male connector 5, and a first piston 2 and a second piston 7 are respectively arranged inside the upper valve body and the lower valve body, so that the control valve as a whole only has two structures, namely, the female connector 4 and the male connector 5, which are communicated with an external pipeline, and the first piston 2 and the second piston 7 respectively control the opening and closing of the female connector 4 and the male connector 5. Taking the matching of the first piston 2 and the upper valve body 1 as an example, as shown in fig. 1, the axis of the female joint 4 is perpendicular to the axis of the upper valve body 1, the first piston 2 moves up and down along the axis direction of the upper valve body 1, when the first piston 2 blocks the female joint 4, the first piston is positioned close to the lower side, the side surface of the first piston 2 is in close contact with the inner wall of the upper valve body 1 to block the connecting port between the female joint 4 and the upper valve body 1, and when the first piston 2 moves up, the connecting port is exposed, so that the upper valve body 1 is communicated with the outside through the female joint 4. When the control valve in the application is used, the upper valve body 1 and the lower valve body 6 are connected and kept fixed with each other, the female connector 4 and the male connector 5 are respectively connected with a gas field water collecting end and an output end, such as a gas field water storage place and a transfer trolley, and it is noted that the connection between the female connector 4 and the male connector 5 and the gas field water collecting end and the output end comprises direct connection or connection through a pipeline and the like. When gas field water is conveyed, a first piston 2 and a second piston 7 in the control valve are respectively positioned at positions close to two ends of an upper valve body 1 and a lower valve body 6, the communication of the space between a male connector 5 and a female connector 4 in the control valve is kept, and the gas field water enters from one connector and flows out from the other connector. After the conveying is finished, one of the pistons is moved to close one joint of the control valve according to the actual setting of the conveying pipeline, then residual gas field water in the control valve is refluxed or drained, and finally the other piston is moved to completely cut off the communication between the control valve and the outside.

Example 2:

this example is further optimized and defined based on example 1.

As shown in fig. 2-3, the upper valve body 1 is connected with the lower valve body 6 by a plug-in connector 9 and a plug-in part 10, the surfaces of the upper valve body 1 and the lower valve body 6 are respectively provided with a limit flange 8, and when the plug-in connector 9 is matched with the plug-in part 10, the two limit flanges 8 are contacted. In this embodiment, one of the upper valve body 1 and the lower valve body 6 is provided with a plug 9 at an axial end, the other valve body is provided with a plug part 10 at the axial end, the upper valve body 1 and the lower valve body 6 are respectively provided with a limit flange 8 at the root of the plug 9 and the root of the plug part 10, the plug 9 can be inserted into the plug part 10 until the two limit flanges 8 are abutted, and finally, the limit flange 8 is provided with a fixing structure and a sealing measure is taken to realize the assembly of the control valve. The limiting flange 8 in this embodiment not only provides a movement end point limitation for the matching of the plug 9 and the plug part 10, but also provides a mounting position for the arrangement of the fixing structure. Furthermore, it should be noted that the detachable connection between the upper valve body 1 and the lower valve body 6 not only allows assembly when the control valve is to be used, but also allows the upper valve body 1 and the lower valve body 6 to be produced separately, and at the same time, the separately produced upper valve body 1 and lower valve body 6 can also be fixedly connected to form a complete control valve, for example by welding at the stop flange 8.

The operating end 3 in this embodiment is a member for controlling the movement of the piston outside the control valve, and the connecting rod 12 is a member for transmitting power between the operating end 3 and the piston. It should be noted that the power source for moving the first piston 2 and the second piston 7 by the movable operation end 3 includes manual operation and automatic operation, when the operation end 3 is driven to move by a device capable of providing power such as a motor, after the piston is moved to a certain position by the motor driving operation end 3, the connection of the motor power output end and the operation end 3 naturally limits the displacement of the operation end 3, so that the operation end 3 and the piston are always fixed under the condition of no power input, and the stability of the control valve in the working process is maintained. Therefore, under the basic requirement of the present application that the control valve can work normally, when the operation end 3 is powered by human operation, any one of the piston, the connection rod 12 or the operation end 3 should have the capability of keeping fixed without human external force input, for example, by the threaded engagement between the operation end 3 and the valve body, and the rotational engagement between the operation end 3 and the connection rod 12, the rotational movement of the operation end 3 can be converted into the linear movement of the piston relative to the valve body, and the engagement between the threads ensures the fixation of the piston in the operation state of the control valve.

In the present embodiment, preferably, an example of a matching structure of the operation end 3 and the control valve is provided, where the operation end 3 includes a cover 301 fixedly connected to the connection rod 12; the end parts of the upper valve body 1 and the lower valve body 6 are provided with external threads 11 at the matching part with the sealing cover 301, and internal threads matched with the external threads 11 are arranged on the circumferential surface of the inner wall of the sealing cover 301. In addition, when the control valve is a structure in which the movement of the piston is controlled by a person in the present application, a handle may be provided on the cover 301 as shown in the drawing.

In this embodiment, preferably, in order to improve the sealing performance of the control valve during the transportation of gas field water, the connecting rod 12 is sleeved with sealing rings which are matched with the inner walls of the upper valve body 1 and the lower valve body 6.
