Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, specifically a high-pressure self-sealing track ball valve. Background Technology

[0002] A ball valve is a valve in which the opening and closing element (the ball) is driven by the valve stem and rotates around the valve's axis. Ball valves are widely used in industries such as petroleum refining, long-distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, power, municipal engineering, and steel, playing a crucial role in the national economy. It has a 90-degree rotational action, and the plug body is a ball with a circular through-hole or channel passing through its axis.

[0003] Chinese Patent CN205978588U discloses a high-pressure self-sealing track ball valve, comprising a valve body, a sealing structure, a bracket, a valve stem, a washer, a ball, a rotating handle, and a bevel gear. This high-pressure self-sealing track ball valve effectively improves the sealing performance of the device by incorporating a sealing ring sleeve and a sealing ring, solving problems such as difficulty in disassembling sealing devices and the difficulty in handling leaks. The graphite packing provides multiple sealing features, reducing the occurrence of accidents. Even in low-pressure environments, the device does not produce micro-leakage, strongly guaranteeing its high sealing performance.

[0004] However, when the ball valve is in use, the friction between the ball and the sealing seat ring caused by the repeated rotation and adjustment of the valve core will cause some wear on the sealing seat ring, which in turn reduces the sealing performance between the ball and the sealing seat ring and reduces its performance. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a high-pressure self-sealing track ball valve.

[0006] The technical solution of this utility model is as follows: a high-pressure self-sealing ball valve, comprising a valve body on which a valve core is disposed; two sets of sealing seats, which are symmetrically disposed inside the valve body and located on both sides of the valve core, the sealing seats being in contact with the ball in the valve core; two sets of abutment seats, which are symmetrically and detachably disposed inside the valve body, with several sets of first springs disposed between the abutment seats and the corresponding sealing seats; and an indication mechanism disposed on the valve body to indicate the degree of wear of the sealing seats.

[0007] Preferably, the abutting seat ring is movably connected to the inner wall of the valve body, and the inner wall of the valve body is also threadedly connected to a ring seat. The abutting seat ring and the ring seat are abutting and connected, and a connecting rod is installed in the middle of the ring seat.

[0008] Preferably, the valve body has an adjustment cavity, and a prompting mechanism is disposed on the adjustment cavity. The prompting mechanism includes a protective box, which is disposed at the top of the outer peripheral surface of the valve body and corresponds to the adjustment cavity; a fixed shaft, which is installed on the inner wall of the protective box, and a pointer is disposed on the outer peripheral surface of the fixed shaft; a gear, which is rotatably connected to the fixed shaft, and a scale mark is disposed on the gear, the scale mark being adapted to the pointer; and a slide rod, which is slidably connected to the adjustment cavity, and a toothed plate is disposed on the slide rod, the toothed plate being meshed with the gear, and an installation component is installed at the other end of the slide rod, the installation component being detachably connected to the sealing seat ring.

[0009] Preferably, the protective box has a door hinged to it, and the end of the door away from the hinge is detachably connected to the protective box by a latch. The protective box has a tempered glass observation window on its side wall.

[0010] Preferably, two sets of limiting sliders are symmetrically arranged on the side wall of the slide rod, and a sliding groove is opened on the side wall of the adjustment cavity, with the limiting sliders slidably connected to the sliding groove.

[0011] Preferably, the mounting assembly includes an elastic element mounted on the slide rod. A protrusion is mounted on the bottom end of the elastic element, and the protrusion abuts against the sealing ring. A groove is provided on the sealing ring, and the protrusion connects with the groove.

Detailed Implementation

[0018] Example 1

[0019] like Figures 1 to 4 As shown, this utility model proposes a high-pressure self-sealing track ball valve, including a valve body 1, a sealing seat ring 2, an abutment seat ring 301, and a prompting mechanism. A valve core 4 is disposed on the valve body 1. Two sets of sealing seat rings 2 are symmetrically arranged inside the valve body 1 and located on both sides of the valve core 4, with the sealing seat rings 2 fitting against the ball in the valve core 4. Two sets of abutment seat rings 301 are symmetrically and detachably disposed inside the valve body 1, with several sets of first springs 3 between the abutment seat ring 301 and the corresponding sealing seat ring 2. The prompting mechanism is disposed on the valve body 1 to display the degree of wear of the sealing seat ring 2, reminding personnel to replace the sealing seat ring 2 in a timely manner to avoid leakage.

[0020] Furthermore, the abutment seat 301 is movably connected to the inner wall of the valve body 1, and the inner wall of the valve body 1 is also threadedly connected to the ring seat 302. The abutment seat 301 and the ring seat 302 are abutted and connected, and a connecting rod 303 is installed in the middle of the ring seat 302. Rotating the connecting rod 303 causes the ring seat 302 to rotate outward of the valve body 1 until the ring seat 302 is separated from the valve body 1. Then, the abutment seat 301 can be held and pulled outward to remove and replace the sealing seat 2.

[0021] In this embodiment, the abutment ring 301 and the sealing ring 2 are inserted into the valve body 1 until the sealing ring 2 is adapted to the valve core 4. The abutment ring 301 is installed inside the valve body 1. At this time, each set of first springs 3 drives the sealing ring 2 to abut against the valve core 4, but does not interfere with the rotation adjustment of the valve core 4. The valve core 4 is rotated for adjustment. When wear occurs at the connection between the ball in the valve core 4 and the sealing ring 2, the sealing ring 2 will move towards the valve core 4 under the elastic recovery action of each set of first springs 3, thereby maintaining the sealing performance at the connection between the sealing ring 2 and the valve core 4 at all times and avoiding leakage. The indicator mechanism reminds the staff of the wear degree of the sealing ring 2 so that the sealing ring 2 can be replaced in time to avoid leakage.

[0022] Example 2

[0023] like Figures 1 to 4As shown, the high-pressure self-sealing ball valve proposed in this utility model, compared with the first embodiment, has an adjustment cavity 101 on the valve body 1, and a prompting mechanism is set on the adjustment cavity 101. The prompting mechanism includes a protective box 5, a fixed shaft 501, a gear 503, and a slide rod 505. The protective box 5 is set at the top of the outer peripheral surface of the valve body 1 and corresponds to the adjustment cavity 101. The fixed shaft 501 is installed on the inner wall of the protective box 5, and a pointer 502 is set on the outer peripheral surface of the fixed shaft 501. The gear 503 is rotatably connected to the fixed shaft 501, and a scale mark 504 is set on the gear 503, which is adapted to the pointer 502. The slide rod 505 is slidably connected to the adjustment cavity 101, and a toothed plate 506 is set on the slide rod 505. The toothed plate 506 is meshed with the gear 503, and an installation component is installed at the other end of the slide rod 505. The installation component is detachably connected to the sealing seat ring 2.

[0024] Furthermore, the protective box 5 is hinged to a door, and the end of the door away from the hinge is detachably connected to the protective box 5 by a latch. The protective box 5 is provided with a tempered glass observation window on its side wall, which facilitates observation of the gear 503 inside the protective box 5 for adjustment.

[0025] Furthermore, two sets of limiting sliders are symmetrically arranged on the side wall of the slide rod 505, and a sliding groove is opened on the side wall of the adjustment cavity 101. The limiting slider is slidably connected to the sliding groove, which facilitates the connection stability between the slide rod 505 and the adjustment cavity 101.

[0026] Furthermore, the mounting assembly includes an elastic element 507; the elastic element 507 is mounted on the slide rod 505, and a protrusion 508 is mounted on the bottom end of the elastic element 507. The protrusion 508 abuts against the sealing ring 2. A groove 201 is provided on the sealing ring 2, and the protrusion 508 is connected to the groove 201. The elastic element 507 is composed of a telescopic rod and a second spring sleeved on the outside of the telescopic rod.

[0027] In this embodiment, when the sealing ring 2 slides inward along the inner wall of the valve body 1 for installation, it pushes the protrusion 508 upward, causing the elastic element 507 to be compressed. When the sealing ring 2 is connected to the valve core 4, the protrusion 508 abuts against the groove 201 under the elastic force of the elastic element 507, thereby completing the connection between the display mechanism and the sealing ring 2. When the sealing ring 2 is worn, it is pushed towards the valve core 4 by the first spring 3. At the same time, the mounting assembly drives the slide rod 505 to slide along the adjustment cavity 101, and then drives the gear 503 to rotate along the fixed shaft 501 through the toothed plate 506. Since the pointer 502 is fixedly connected to the fixed shaft 501, the scale mark 504 follows the rotation of the gear 503, and the pointer 502 points to the mark 504, which changes. The changes can be observed in real time through the tempered glass observation window on the protective box 5. When the sealing ring 2 is worn to a certain extent, to avoid leakage, the staff can disassemble and replace the sealing ring 2.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
