Embodiment 1

[0052] This embodiment provides a main valve of a two-position four-way plug valve, such as Figure 2 to Figure 5 As shown, the valve body 11 is included, the valve body 11 is provided with a first channel 12, a second channel 13, a third channel 14 and a fourth channel 15, a cock 16 is installed in the valve body 11, and the upper end of the cock 16 is affixed to the upper The shaft 17 protrudes from the upper end cap 18 installed on the upper end of the valve body 11, and the lower shaft 19 fixedly connected to the lower end of the cock 16 protrudes from the lower end cap 110 installed on the lower end of the valve body 11, so that the cock 16 can lift and rotate in the valve body 11;

[0053] The cock 16 is processed along the direction perpendicular to the axis of the cock 16 with flow passages 111 passing through the end faces of the two ends of the cock 16. Sealing slides 112 are installed on the outer walls of the cock 16 on both sides of the flow passage 111. The cock 1...

Embodiment 2

[0058] This embodiment provides an operator of a two-position four-way plug valve, such as Figure 6 to Figure 8 As shown, it includes a housing 21 with both ends open, and an upper valve stem 22, a middle valve stem 23 and a lower valve stem 24 arranged in sequence from top to bottom are installed in the housing 21, and the middle valve stem 23 and the lower valve stem 24 are both It is a hollow valve stem, the lower outer wall of the upper valve stem 22 is connected with the inner wall of the middle valve stem 23 through the first transmission thread 25, and the lower outer wall of the middle valve stem 23 and the inner wall of the lower valve stem 24 are connected through the second transmission thread 26 are connected, and the helical direction of the first drive thread 25 and the second drive thread 26 is opposite;

[0059] The middle outer wall of the upper valve stem 22 is processed with an upper roller chute 27, the upper part of the middle valve stem 23 is processed w...

Embodiment 3

[0065] This embodiment provides a two-position four-way plug valve, such as Figure 1 to Figure 8 As shown, it includes a main valve 1 and an operator 2. The operator 2 is installed on the main valve 1. The upper shaft 17 of the main valve 1 is connected with the lower valve stem 24 of the operator 2, so that the operator 2 drives the main valve 1 to work.

[0066] In this embodiment, the main valve 1 adopts the main valve of the two-position four-way plug valve described in the first embodiment.

[0067] In this embodiment, the manipulator 2 adopts the manipulator of the two-position four-way plug valve described in the second embodiment.

[0068] The guide pin 217 in the operator 2 moves from the top of the first vertical groove 2161 to the bottom of the groove and enters one end of the horizontal groove 2162, and the cock 16 in the main valve 1 rises to the upper limit position, so that the sealing slide 112 and the channel The end surface 113 is disengaged; the guide pin ...

Abstract

The invention provides a two-position four-way plug valve, which comprises a main valve and an operating device. The operating device is mounted on the main valve, a guide pin in the operating devicemoves from the top of a first vertical groove to the bottom of the same to enter one end of a transverse groove, and a plug in the main valve moves up to an upper extreme position to enable a seal slide sheet to move away from the end face of a passage; the guide pin in the operating device moves from one end of the transverse groove to the other end so as to enter the bottom of a second verticalgroove, and the plug in the main valve drives the seal slide sheet to rotate; the guide pin in the operating device moves from the bottom of the second vertical groove to the top of the same, and theplug in the main valve moves downwards to a lower extreme position to enable contact seal of the seal slide sheet and the end face of the passage. The valve is high in circulation performance and sealing reliability, wedged active sealing avoids seal ring abrasion, low operating torque is realized, the service life of the valve is greatly prolonged, and the valve can be widely applied to oil metering, oil conveying switching and the like in the industry of petrochemical engineering.

Description

technical field [0001] The invention belongs to the field of valves and relates to a plug valve, in particular to a two-position four-way type plug valve, a main valve and an operator. Background technique [0002] The two-position four-way plug valve is a plug valve with a four-way structure. Its four-way valve body structure can be connected with up to four pipelines. The unique cock (spool) structure ensures that the valve There are at least two pipelines connected, and the connection or disconnection between the pipelines can be freely controlled by connecting the operator structure and the actuator, so as to realize the functions of cutting off the medium in the pipeline and switching the flow direction. It can be widely used in occasions such as oil metering and oil delivery pipeline switching in the petroleum industry. [0003] At present, in the transfer measurement of oil product trade, the method of calibrated volume tube is usually used to measure the oil product...
