Problems solved by technology

[0004] The technical problem to be solved by this invention is that the gas provided by the external force mechanism and the gas inside the pipeline cannot be mixed uniformly and reach a stable air pressure before reaching the safety valve in the on-line detection of the safety valve pressure. The purpose is to provide a multifunctional Ball valve, to solve the problem of how to use the ball valve to flexibly control the confluence, diversion, and flow switching of the medium, so that the gas provided by the external force mechanism can be evenly mixed with the gas inside the pipeline to improve the accuracy of the detection results

Embodiment 1

[0023] Such as figure 1 As shown, a multifunctional ball valve for safety valve pressure test equipment of the present invention includes a valve body 1, and a channel 2 is arranged inside the valve body 1, and the channel 2 is connected to both ends of the valve body 1, and the two ends of the valve body 1 A sealing seat 3 is fixed at the end, and the sealing seat 3 communicates with the channel 2. The inside of the valve body 1 is provided with a sphere 4 with a built-in channel, and the sphere 4 is located in the channel 2. A valve stem 5 is connected, one end of the valve stem 5 is connected to the ball 4 , the other end of the valve stem 5 passes through the valve body 1 , and a through hole 6 is opened on one side wall of the valve body 1 , and the through hole 6 communicates with the channel 2 . The through hole 6 is a circular through hole and the inner surface of the through hole 6 is smooth. The center of the sphere 4 is on the extension line of the axis of the thro...

Embodiment 2

[0026] Based on Embodiment 1, the valve stem 5 is connected with a handle 7, and the handle 7 is covered with a heat insulating layer. A signal sensor is installed on the inner wall of the channel 2 between the through hole 6 and the gas outlet of the valve body 1, and the signal sensor is a temperature and pressure signal sensor. During the operation of the equipment, the high-pressure environment is generally accompanied by the high-temperature environment. The operator turns the valve stem by the handle, and the valve stem drives the ball to rotate. The valve stem and the wiper are generally made of stainless steel. Stainless steel has a heat conduction effect. Therefore, heat insulation layer to avoid high temperature burns to the operator; the signal sensor is used to measure the initial mixing pressure of the mixed gas. The signal sensor can always collect the mixed pressure during the gas mixing process. The signal sensor can choose to adjust the gas mixing rate and moni...

Abstract

The invention discloses a multifunctional ball valve for a safety valve pressure test device. The multifunctional ball valve for the safety valve pressure test device comprises a valve body which is internally provided with a channel; the channel is communicated to the two ends of the valve body; sealing bases are fixed to the two ends of the valve body and are communicated with the channel; the valve body is internally provided with a ball body internally provided with a hole channel; the ball body is located in the channel; one side wall, not provided with the hole channel, of the ball body is connected with a valve rod; one end of the valve rod is connected with the ball body, and the other end of the valve rod penetrates the valve body; and one side wall of the valve body is provided with a through hole which is communicated with the channel. According to the multifunctional ball valve for the safety valve pressure test device, the side wall of the ball valve is provided with the through hole which is connected with an external force mechanism, the beneficial effects that the ball valve flexibly controls flow converging and flow dividing of media are utilized so that gas provided by the external force mechanism and gas in a pipeline can be uniformly mixed and pressure can be stably tested, the safety valve detection result accuracy is improved, and the detection time is shortened.

Description

technical field [0001] The invention relates to a ball valve, in particular to a multifunctional ball valve for safety valve pressure test equipment. Background technique [0002] In the pressure test of the safety valve, an external force mechanism must be added to add external force to the pipeline. The installation of the external force mechanism is complicated, it is not easy to operate on site, and the on-line detection of the safety valve takes a long time; It takes a long time to reach a stable safety valve test pressure, and once the gas provided by the external force mechanism and the gas inside the pipeline cannot be uniformly mixed before reaching the safety valve, the test result of the safety valve is inaccurate. [0003] The ball valve can flexibly control the confluence, diversion, and switching of the flow direction of the medium on the pipeline. It only needs to rotate 90 degrees and a small rotational torque to close tightly. Ball valves are most suitable ...
