Detailed Description
The technical scheme of the utility model is described in detail below with reference to the accompanying drawings. It should be emphasized that the following examples are illustrative, in which all technical and scientific terms used have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs.
The embodiment is a pressure on-line measuring valve for easy crystallization operating mode, including valve body 1, case 2 and pressure detector 3, valve body 1 adopts six-way valve that all is equipped with the opening about its front and back, case 2 is located valve body 1 inner chamber, pressure detector 3 demountable installation is on case 2.
Referring to fig. 1 and 2, the valve body 1 includes a left pipe port 11, a right detection port 12, an upper valve stem port, a front and rear mounting and dismounting ports 9 and a lower drain 4. The pipeline port 11 is used for connecting a pipeline, the detection port 12 is used for entering and exiting electrical elements such as the signal wire 6, the valve rod port is used for placing the valve rod 8, and the dismounting port 9 is used for dismounting the pressure detector 3. The sewage outlet 4 is provided with a switch valve, and the switch valve can be a ball valve. The detection port 12 and the dismounting port 9 are both provided with plugs when pressure detection is not needed.
The valve core 2 is provided with a connecting groove 21 above for connecting a valve rod 8, the valve rod 8 is used for controlling the valve core 2 to rotate, as shown in fig. 2, the valve core 2 is provided with a horizontal through hole, the through hole is communicated with the front and rear dismounting ports 9, and when in a detection state, the through hole is used for communicating the pipe orifice 11 with the detection port 12.
The through hole is internally provided with an internal thread 22, and the pressure detector 3 is provided with an external thread 31 matched with the internal thread 22, so that the two can be detachably connected.
The detection port 12 is connected with a flange 5, when pressure detection is not needed, the valve body 1 is blocked by the flange 5 to normally operate, and when detection is needed, electrical elements such as a signal wire 6 of the pressure detector 3 can enter and exit through the detection port 12. The signal line 6 is plugged into a mating connector 32 at the rear end of the pressure detector 3, after which the plug-in connection is sealed with a sealing head 7.
The process of pressure detection using the valve is:
(1) the through hole of the valve body 2 communicates with the attachment/detachment port 9 (corresponding to the valve closing), the pressure detector 3 is attached to the through hole from the attachment/detachment port 9, and then the attachment/detachment port 9 is closed by a cap or a plug.
(2) The sewage outlet 4 is opened, the valve rod 8 is rotated to enable the valve core 2 to horizontally rotate until the through hole of the valve core is communicated with the pipeline opening 11 and the detection opening 12 (corresponding to the opening of the valve), and sewage is discharged.
(3) Closing the drain outlet 4, extending the signal wire 6 from the detection port 12 into the valve body 1, inserting the signal wire 6 into the pressure detector 3, sealing the insertion position by using the sealing head 7, sealing and plugging the detection port 12 by using the flange 5, reserving a signal wire 6 channel on the flange 5, and then detecting the pressure.
