Abstract

The utility model relates to the technical field of slurry valves, and discloses an electro-hydraulic integral slurry valve which comprises an integral slurry valve body and a valve plate which is arranged in the integral slurry valve body and used for controlling flowing and closing of media. When the valve plate 2 in the integral slurry valve body 1 moves downwards, the valve plate 2 can be used for sealing through two groups of O-shaped sealing gaskets 8, an elastic sealing gasket 9 protrudes upwards in a default state, when the valve plate 2 moves downwards to extrude the interior of a sealing groove, the elastic sealing gasket 9 is pressed into the sealing groove at the same time, and when the valve plate 2 is opened upwards, the elastic sealing gasket 9 is pressed into the sealing groove. The elastic sealing pad 9 resets and bounces upwards through the elasticity of the elastic sealing pad 9, at the moment, when a circulating medium passes through the elastic sealing pad 9, impurities mingled in the medium cannot permeate into a sealing groove in the integral slurry valve body 1 under blocking of the elastic sealing pad 9, and therefore the purpose that the impurities in the medium are prevented from permeating into the sealing groove is achieved. And the medium sealing property of the valve plate 2 is improved.

Description

Technical Field

[0001] The utility model relates to the technical field of slurry valves, in particular to an electro-hydraulic integral slurry valve. Background Technique

[0002] The electro-hydraulic integral slurry valve is a pipeline valve for slurry widely used in multiple industries such as mining and the iron and steel industry.

[0003] In the existing integral electro-hydraulic slurry valve, the inner ring seal of the valve body itself adopts an "O"-type composite sealing ring structure. However, when the valve plate moves upward to open, when the medium flows inside the valve body, impurities and other pollutants in the medium are likely to accumulate and stay inside when passing through the internal sealing groove of the valve body. As a result, when the valve plate moves downward to close, it gets stuck with the sealing groove, affecting the sealing performance of the sealing groove itself and reducing the sealing effect. For this reason, we propose an electro-hydraulic integral slurry valve. Content of the Utility Model

[0004] The utility model mainly solves the technical problem that when the existing slurry valve moves upward to open, after the medium flows inside the valve body, impurities and other pollutants in the medium are likely to accumulate and stay inside when passing through the internal sealing groove of the valve body. It provides an electro-hydraulic integral slurry valve with a set of connecting convex pads connected to the O-shaped sealing pad for sealing and blocking inside the sealing groove of the slurry valve, preventing impurities from penetrating into the groove and causing accumulation.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme. An electro-hydraulic integral slurry valve includes an integral slurry valve body and a valve plate arranged inside the integral slurry valve body for controlling the flow and closing of the medium. At the top of the integral slurry valve body, there is an electro-hydraulic actuator arranged through a support seat, which can perform electro-hydraulic control on the valve plate inside the integral slurry valve body. Inside the support seat, there is a driving rod whose upper and lower ends are respectively connected to the electro-hydraulic actuator and the valve plate for driving and controlling. The outer wall of the integral slurry valve body is fixedly installed with a mounting flange integrally formed with the integral slurry valve body. An O-shaped groove for sealing cooperation with the valve plate is provided on the inner wall surface of the integral slurry valve body. On both corresponding sides inside the O-shaped groove, there are O-shaped sealing pads for sealing both sides of the valve plate. The outer walls of the two groups of O-shaped sealing pads are fixedly connected together through an elastic sealing pad.

[0006] Preferably, the elastic sealing pad has elastic deformable characteristics and the elastic sealing pad is in the shape of three-quarters of a circle.

[0007] Preferably, the elastic sealing pad has an upward convex appearance in its default state. After being squeezed by the valve plate, the elastic sealing pad will deform downward to ensure the edge sealing between the two groups of O-shaped sealing pads, and the elastic sealing pad will reset upward to a convex state when there is no extrusion.

[0008] Preferably, a scraping member is fixedly installed on the inner circumferential wall surface of the integral slurry valve body, which can scrape and clean impurities on the side of the valve plate close to the water inlet end of the integral slurry valve body when the valve plate is controlled to open upward.

[0009] Preferably, the scraping member has an arc-shaped appearance, and the side of the scraping member close to the valve plate is in a state of mutual fitting and scraping with the side of the valve plate close to the water inlet end of the integral slurry valve body.

[0010] Beneficial effects

[0011] The utility model provides an electro-hydraulic integral slurry valve, which has the following beneficial effects:

[0012] (1). For the electro-hydraulic integral slurry valve, the overall device on the integral slurry valve body 1 can be applied in multiple fields to control the opening and closing of different flowing media. The inner circumferential seal of the traditional integral electro-hydraulic slurry valve adopts an "O"-type composite sealing ring structure. However, when the valve plate moves upward to open, when the medium flows inside the valve body, impurities and other pollutants in the medium are likely to accumulate and stay inside when passing through the internal sealing groove of the valve body, resulting in jamming between the valve plate and the sealing groove when the valve plate moves downward to close, affecting the sealing performance of the sealing groove itself and reducing the sealing effect. The valve plate 2 inside the integral slurry valve body 1 can be sealed by two groups of O-shaped sealing gaskets 8 when moving downward, and the two groups of O-shaped sealing gaskets 8 are fixedly connected inside the sealing groove through an elastic sealing gasket 9. The elastic sealing gasket 9 has an upward convex appearance in the default state. When the valve plate 2 moves downward and squeezes the inside of the sealing groove, the elastic sealing gasket 9 will be simultaneously pressed into the sealing groove. When the valve plate 2 opens upward, the elastic sealing gasket 9 will bounce back upward through its own elasticity. At this time, when the flowing medium passes through the elastic sealing gasket 9, the impurities in the medium are blocked by the elastic sealing gasket 9 and cannot penetrate into the internal sealing groove of the integral slurry valve body 1, thereby achieving the effect of avoiding the penetration of impurities in the medium into the sealing groove and improving the medium sealing characteristics of the valve plate 2.

[0013] (2). For the electro-hydraulic integral slurry valve, a component that can fit with the side of the valve plate 2 close to the water inlet end is installed on the inner wall of the top of the sealing groove of the integral slurry valve body 1. When the valve plate 2 moves upward to open, the valve plate 2 will fit and scrape against one side of the scraping member 10 during the movement, avoiding the adsorption and penetration of impurities on the valve plate 2 itself into the sealing groove, thereby achieving the effect of automatically cleaning the adsorbed substances on the valve plate 2 itself and assisting in improving the sealing performance of the valve plate 2.

[0023] Embodiment: An electro-hydraulic integral slurry valve, as Figures 1 - 4As shown in the figure, it includes an integral slurry valve body 1 and a valve plate 2 arranged inside the integral slurry valve body 1 for controlling the flow and closing of the medium. At the top of the integral slurry valve body 1, there is a electro-hydraulic actuator 4 arranged through a support seat 3, which can perform electro-hydraulic execution control on the valve plate 2 inside the integral slurry valve body 1. Inside the support seat 3, there is a driving rod 5 whose upper and lower ends are respectively connected and controlled to drive the electro-hydraulic actuator 4 and the valve plate 2 itself.

[0024] The working principle of the present utility model:

[0025] The overall device on the integral slurry valve body 1 can be applied in multiple fields to control the opening and closing of different flowing media. When the valve plate 2 inside the integral slurry valve body 1 moves downward, it can be sealed by two groups of O-shaped gaskets 8. And the two groups of O-shaped gaskets 8 are fixedly connected inside the sealing groove through an elastic gasket 9. The elastic gasket 9 has an upwardly convex appearance in its default state. When the valve plate 2 moves downward and squeezes the inside of the sealing groove, the elastic gasket 9 will be simultaneously pressed into the sealing groove. When the valve plate 2 is opened upward, the elastic gasket 9 will reset upward by its own elasticity. At this time, when the flowing medium passes through the elastic gasket 9, the impurities mixed in the medium cannot penetrate into the sealing groove inside the integral slurry valve body 1 under the block of the elastic gasket 9, thus avoiding the penetration of impurities in the medium into the sealing groove and improving the medium sealing characteristics of the valve plate 2.
