Description

TECHNICAL FIELD

[0001] The utility model relates to double discharge ball valve technical field, concretely is a new type sealing ring groove ball valve. BACKGROUND

[0002] Double discharge ball valve has two independent discharge channels. Usually two different discharge ports are arranged at the bottom or side of the valve, which can be used for different purposes. For example, in some chemical processes, one discharge port can be used to discharge liquid medium in the pipeline, such as chemical raw materials or reaction products; another discharge port can be used to discharge gas, such as by-product gas generated in some reaction processes. Its main structure is still based on the principle of ball valve. The ball is the core component, and the ball has a circular through hole. When the valve is fully open, the through hole of the ball is aligned with the inner diameter of the pipeline, and the medium can flow smoothly; when the valve is closed, the ball is rotated by 90 degrees, and the solid part of the ball cuts off the pipeline to prevent the medium from flowing. The ball is usually made of metal (such as stainless steel, carbon steel, etc.) to ensure its strength and corrosion resistance, and can withstand certain pressure and medium erosion.

[0003] When operating the double-plugging double-discharge ball valve, the synchronous action of the two balls needs to be ensured to achieve effective cutting and discharge function. If not operated properly, it may cause problems such as valve sealing and poor discharge. Therefore, a corresponding control device is needed to ensure accurate operation of the valve.

The top of the valve rod 28 is fixedly connected with a positioning rod 29, the outer wall of the positioning rod 29 is fixedly connected with a limiting strip 210, the inner part of the worm wheel 26 is movably connected with the outer wall of the positioning rod 29 and the limiting strip 210. One end of the worm 27 is fixedly connected with a rotating disc handle 211.

[0030] In specific implementation: when it is needed to control the valve balls at one end of the two valve rods 28 at the same time, first insert the supporting rod 22 into the mounting block 21, at the same time the worm wheel 26 will be above the positioning rod 29, as the supporting rod 22 is inserted into the mounting block 21, the worm wheel 26 will also be sleeved on the outer wall of the positioning rod 29, then rotate the rotating disc handle 211 to drive the worm 27 to rotate, the worm 27 drives the worm wheel 26 to rotate, the worm wheel 26 drives the positioning rod 29 and the valve rod 28 to rotate through the transmission of the limiting strip 210, so that the valve balls at the ends of the two valve rods 28 can be controlled at the same time.

[0031] Referring to Figures 1 to 4In one aspect of the embodiment, the auxiliary assembly 3 comprises a hand wheel 31, and a cross-shaped insertion rod 32 is fixedly connected to the bottom of the hand wheel 31. A cross-shaped insertion hole 33 is formed in the top of the positioning rod 29. A flowmeter 34 is fixedly installed on the outer wall of the valve body 1, and the probe of the flowmeter 34 is fixed in the valve body 1. An electromagnetic valve 35 is fixedly installed on the outer wall of the conduit on one side of the valve body 1.

[0032] In specific implementation: when a single valve ball needs to be controlled, the assembled frame 23 can be pulled out as a whole, and then the cross-shaped insertion rod 32 at the bottom of the hand wheel 31 is inserted into the cross-shaped insertion hole 33, so that the single valve rod 28 can be rotated by rotating the hand wheel 31. When the two valve balls are closed at the same time, liquid will be left in the pipeline between the two valve balls.

As the support rod 22 is inserted into the mounting block 21, the worm gear 26 is also sleeved on the outer wall of the positioning rod 29. Then the worm gear 27 is rotated by rotating the rotating disc handle 211, and the worm gear 27 drives the worm gear 26 to rotate. The worm gear 26 drives the positioning rod 29 and the valve rod 28 to rotate through the transmission of the limiting strip 210. In this way, the two valve balls at the end of the valve rod 28 can be controlled at the same time. When a single valve ball needs to be controlled, the assembled frame 23 can be pulled out as a whole, and then the cross-shaped insertion rod 32 at the bottom of the hand wheel 31 is inserted into the cross-shaped insertion hole 33, so that the single valve rod 28 can be rotated by rotating the hand wheel 31. When the two valve balls are closed at the same time, liquid will be left in the pipeline between the two valve balls. When the flowmeter 34 detects that the liquid flow rate at this position is zero, it means that the two ball valves have been closed and completed, and the electromagnetic valve 35 can be started to open the valve port to drain the liquid from the conduit.
