Description

TECHNICAL FIELD

[0001] The present patent relates to an electric grease valve device. BACKGROUND

[0002] In modern industrial production, the stability and efficiency of lubrication systems are crucial for the operation of equipment. Especially in large mechanical equipment, grease delivery devices play a key role in reducing mechanical wear and extending the service life of equipment. However, in the existing technology, there are still many deficiencies in the design of grease delivery valves, which are specifically manifested in the following aspects:

[0003] Poor sealing performance, prone to grease leakage

[0004] Many existing grease valve sealing designs lack dynamic adaptability, especially during the movement of the piston, the cooperation between the sealing ring and the inner wall of the channel or the piston is not tight enough, resulting in grease leakage. This not only wastes lubricating materials, but also pollutes the equipment environment, increasing cleaning and maintenance costs.

[0005] Cannot realize remote control, inconvenient operation

[0006] Traditional grease valves mainly rely on manual or close-range electric control to open or close the oil passage. This control method is extremely inconvenient when the equipment is complex or the valve body installation position is difficult to access, especially in outdoor or high-risk operating environments, which poses a safety hazard to operation.

[0007] Insufficient environmental adaptability

[0008] Many existing grease valve designs do not fully consider the application requirements of outdoor or special environments. For example, in humid, dusty or high-temperature environments, some valve body components and control devices are prone to failure, affecting the overall work efficiency and service life of the equipment.

[0009] In summary, the technical background part of the present patent aims to describe the current status of the existing technology, and the deficiencies of the existing technology show that this part will provide necessary background information for understanding the technical contributions and innovation points of the present patent. The signals disclosed in this background technology part only aim to increase the understanding of the overall background of the present patent, and should not be considered as implying subjective consciousness in any form.

[0010] In view of the above, the purpose of the present patent is to provide an electric grease valve device.

[0011] The technical scheme adopted to achieve the purpose of the patent is an electric grease valve device, comprising a valve body, an electric telescopic rod, a one-way valve and a two-way remote controller. The valve body is a one-piece hollow structure, comprising an upper housing, a lower housing and an inner cavity. The inner cavity is provided with a through oil passage, the axis of the oil passage extends along the longitudinal direction of the valve body, the oil inlet of the oil passage is arranged on the side of the lower housing and is connected to an external grease storage device through threads, a filter screen is arranged at the oil inlet to prevent impurities from entering, the oil outlet of the oil passage is arranged at the top of the upper housing and is connected to an oil conveying pipeline, a mounting flange is arranged on the outer part of the valve body for fixing the valve body on an industrial equipment through bolt connection to ensure stable connection with the equipment; the electric telescopic rod comprises a fixed end and a piston rod, the piston rod is connected to a piston inside the valve body, the piston is located in the oil passage and can slide axially along the oil passage; the one-way valve is installed at the oil outlet for controlling the one-way flow of the grease; the two-way remote controller is electrically connected with the electric telescopic rod to realize the contraction or elongation of the piston in the oil passage, thereby controlling the opening and closing of the oil passage.

[0012] Further, the upper housing and the lower housing of the valve body are connected through threads, and a sealing ring is arranged at the joint to prevent grease leakage.

[0013] Further, the piston and the inner wall of the oil passage are sealed by a sealing ring to prevent grease leakage in the closed state.

[0014] Further, the inner oil passage of the valve body is provided with a plurality of annular grooves for installing O-shaped sealing rings, and the sealing rings cooperate with the piston to ensure the dynamic sealing property of the oil passage.

[0026] The specific embodiments of the present patent will be described in detail below with reference to the drawings, so that the technical content of the present patent can be better understood, but the present patent should not be limited thereto.

[0027] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict, and the present patent will be described in detail below with reference to the drawings and in combination with the embodiments.

[0028] As Figs. 1-2 shown, the present patent provides an electric grease valve device, which specifically comprises a valve body, an electric telescopic rod, a one-way valve and a two-way remote controller.

[0029] Embodiment 1: basic structure and working principle

[0030] 1. Valve body structure

[0031] The valve body is a one-piece hollow structure, which is mainly composed of an upper shell, a lower shell and an inner cavity.

[0032] Inner cavity: the inner cavity is provided with a through oil passage, and the axis thereof extends along the longitudinal direction of the valve body. The oil passage is used for the flow of grease.

[0033] Oil inlet: the oil inlet of the oil passage is arranged on the side surface of the lower shell and is connected to the external grease storage equipment through threads. A filter screen is arranged at the oil inlet for blocking impurities from entering the inner cavity.

[0034] Outlet: The oil outlet of the oil passage is located at the top of the upper shell and is connected with the oil pipeline.

[0035] Sealing structure: The upper shell and the lower shell are connected by threads, and a sealing ring is installed at the joint to ensure the oil seal of the connection. The valve body is externally provided with a mounting flange, which is fixed to the industrial equipment by bolts to achieve stable installation.

[0036] 2. Electric telescopic rod

[0037] The electric telescopic rod includes a fixed end and a piston rod.

[0038] The piston rod is fixedly connected with a piston in the valve body, and the piston is located in the oil passage and can slide axially along the oil passage.

[0039] The surface of the piston is sealed with the inner wall of the oil passage by a sealing ring, thereby preventing oil leakage in the closed state. The inner wall of the oil passage is provided with a plurality of annular grooves for installing O-shaped sealing rings to ensure dynamic sealing performance.

[0040] 3. One-way valve

[0041] The one-way valve is installed at the oil outlet of the oil passage to ensure that the oil can only flow in one direction, avoiding backflow problems.

[0042] 4. Two-way remote control

[0043] The two-way remote control is electrically connected with the electric telescopic rod by wires to control the extension or shortening action of the electric telescopic rod. Specifically:

[0044] First control signal: drive the electric telescopic rod to move, so that the piston moves axially outward along the oil passage, thereby opening the oil passage. At this time, the oil enters through the oil inlet and flows out through the oil outlet.

[0045] Second control signal: drive the electric telescopic rod to move in the opposite direction, so that the piston moves axially inward along the oil passage, thereby closing the oil passage. At this time, the oil flow stops.

[0046] Working process

[0047] The working process of the device is as follows:

[0048] 1. Open the oil passage

[0049] When oil needs to be transported, the first control signal is sent through the two-way remote control, the electric telescopic rod is powered on, and the piston rod drives the piston to move outward along the oil passage. With the movement of the piston, the oil passage is opened, the oil enters from the oil inlet, flows out through the oil outlet, and is transported to the industrial equipment that needs to be lubricated through the one-way valve.

[0050] 2. Close the oil passage

[0051] When the oil delivery reaches the set requirement, a second control signal is sent through the two-way remote controller, the electric telescopic rod is reversed, driving the piston rod to move the piston inward along the oil channel. With the movement of the piston, the oil channel gradually closes until the oil flow channel is completely blocked, and the delivery process ends.

[0052] Example 2: Improved sealing design

[0053] In this embodiment, to further improve the sealing performance during oil delivery, multiple sets of annular grooves are evenly distributed on the inner wall of the oil channel of the valve body for installing O-rings.

[0054] Dynamic sealing performance: The O-ring closely cooperates with the outer surface of the piston, ensuring efficient sealing during the movement of the piston and preventing oil leakage.

[0055] Wear-resistant design: The sealing ring material is made of high-molecular material with good wear resistance to prolong the service life of the device.

[0056] The above specific embodiments are typical embodiments of the patent, but the patent is not limited to this. Reasonable changes can be made to the structure, material and control logic without deviating from the core technical idea of the patent. All improvements based on this fall within the scope of protection of the patent.

[0057] The specific embodiments of the patent are only illustrative and do not limit the scope of protection of the patent. Various changes and modifications can be made to the specific embodiments of the patent without departing from the spirit and essence of the patent. These changes and modifications are within the scope of the patent.

[0058] It is worth noting that in the description of the patent, "multiple" means two or more, unless otherwise specified. In the patent, unless otherwise specified and limited, the terms "installation", "connection", "connection", "fixing" and other terms should be understood broadly, for example, they can be fixedly connected, or detachably connected, or integrally connected; they can be mechanically connected; the circuits described in the patent are commonly used circuits in the art, and other related components are commonly used components in the art. For those skilled in the art, the specific meaning of the above terms in the patent can be understood according to the specific circumstances.

[0059] It is apparent for a person skilled in the art that the present patent is not limited to the details of the above-described exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or essential characteristics of the patent, and that the embodiments should therefore be considered as exemplary and non-limiting, the scope of the patent being defined by the claims that follow and not by the above description, and that all changes falling within the meaning and range of equivalency of the claims' essential elements are therefore intended to be embraced therein, and that no reference sign in the claims should be considered as limiting the claims to the involved reference sign.
