Adjustable pressure ball valve with automatic compensation

Abstract

This utility model discloses an adjustable pressure ball valve with automatic compensation, relating to the field of ball valve technology. It includes a valve body, with a connecting frame fixedly installed at the center of the valve body surface. A filling groove begins at the center of the connecting frame, and a pressure cap is slidably connected inside the filling groove. A valve stem is rotatably connected at the center of the pressure cap. Warning components are provided on both sides of the top of the pressure cap. Each warning component includes a cylinder fixedly installed on both sides of the top of the pressure cap. Several spring plates are fixedly installed inside the cylinder, and a fixing bolt is provided at the top of the cylinder. A limiting rod penetrating the spring plates and the pressure cap is fixedly installed at the center of the bottom of the fixing bolt. When the water flow inside the valve body increases due to water-absorbing beads filled in the filling groove, the beads absorb the seeping water and expand, thus lifting the pressure cap. At this time, the cylinder moves upward synchronously with the cap. The combination of the spring plates and the fixing bolt generates downward pressure on the cap, preventing water leakage and increasing the sealing performance of the valve body.

Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, specifically to an adjustable pressure ball valve with automatic compensation. Background Technology

[0002] A ball valve is a valve in which the valve stem drives the valve's opening and closing mechanism, causing the valve to rotate around its axis. It can also be used for fluid regulation and control. Hard-seal V-type ball valves, in particular, have a strong shearing force between the V-shaped ball core and the metal seat with hard alloy overlay, making them especially suitable for media containing fibers or small solid particles. Multi-port ball valves not only allow for flexible control of media merging, splitting, and switching of flow direction in pipelines, but also allow the closure of any channel while connecting two other channels.

[0003] Existing ball valves cannot automatically compensate and adjust according to the internal pressure of the valve body. Over time, this may lead to a decrease in the sealing performance of the ball valve, resulting in water leakage. To address this issue, an adjustable pressure ball valve with automatic compensation is proposed. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide an adjustable pressure ball valve with automatic compensation.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: an adjustable pressure ball valve with automatic compensation, comprising a valve body, a connecting frame fixedly installed at the center of the surface of the valve body, a filling groove starting at the center of the connecting frame, water-absorbing beads provided inside the filling groove, a pressure cap slidably connected inside the filling groove, a valve stem rotatably connected at the center of the pressure cap, and warning components provided on both sides of the top of the pressure cap;

[0006] The warning component includes cylinders fixedly installed on both sides of the top of the cover. Several spring plates are fixedly installed inside the cylinders. A fixing bolt is provided at the top of the cylinders. A limiting rod that penetrates the spring plates and the cover is fixedly installed at the center of the bottom end of the fixing bolt.

[0007] Preferably, the spring plates are arranged in a V-shape inside the cylinder.

[0008] Preferably, the fixing bolt slides inside the cylinder.

[0009] Preferably, bearings are provided at the junctions of the valve stem, the gland, and the connecting frame.

[0010] Preferably, a ball valve is provided on the side of the valve stem located inside the valve body, and a sealing ring is provided at the intersection of the ball valve and the inner wall of the valve body.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] When the water flow inside the valve body increases, the water-absorbing beads filled in the filling groove absorb the seeping water and expand, thus lifting the gland. At this time, the cylinder moves upward synchronously with the cover plate. The combination of the spring plate and the fixing bolt generates downward pressure on the cover plate to prevent water leakage and increase the sealing performance of the valve body.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Figures 1-4As shown, this utility model provides an adjustable pressure ball valve with automatic compensation, including a valve body 100. A connecting frame 900 is fixedly installed at the center of the surface of the valve body 100. A filling groove 500 is formed at the center of the connecting frame 900. Water-absorbing beads are provided inside the filling groove 500. The water-absorbing beads absorb the seeping water and expand, thereby increasing their volume and squeezing the pressure cap 200, causing the pressure cap 200 to move upward inside the connecting frame 900. The pressure cap 200 is slidably connected inside the filling groove 500. A valve stem 400 is rotatably connected at the center of the pressure cap 200. Warning components 300 are provided on both sides of the top of the pressure cap 200.

[0021] The warning component 300 includes a cylinder 1010 fixedly installed on both sides of the top of the pressure cover 200. Several spring plates 800 are fixedly installed inside the cylinder 1010. The spring plates 800 are arranged in a V-shape inside the cylinder 1010. A fixing bolt 700 is provided at the top of the cylinder 1010. When the pressure cover 200 moves upward, the cylinder 1010 moves upward simultaneously. The fixing bolt 700 squeezes the spring plates 800 inside the cylinder 1010. The elastic force of the spring plates 800 applies pressure to the pressure cover 200. A limiting rod 600 that penetrates the spring plates 800 and the pressure cover 200 is fixedly installed at the center of the bottom end of the fixing bolt 700. The fixing bolt 700 slides inside the cylinder 1010.

[0022] Bearings are provided at the junctions of the valve stem 400, the gland 200, and the connecting frame 900.

[0023] By adopting the above technical solution, the bearing is designed to reduce the friction between the valve stem 400 and the gland 200, the connecting frame 900 and the valve body 100.

[0024] A ball valve is provided on one side of the valve stem 400 inside the valve body 100, and a sealing ring is provided at the intersection of the ball valve and the inner wall of the valve body 100.

[0025] By adopting the above technical solution, the rotating valve stem 400 can drive the ball valve inside the valve body 100 to open or close, and the sealing ring enhances the sealing performance of the ball valve.

[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
