Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to an assembled gate valve. Background Technology

[0002] Gate valves are widely used control devices in pipeline systems, primarily used to open or close the flow of fluid in pipelines. Gate valves control the flow of fluid by moving a gate up and down, playing a crucial role in industries such as petroleum, chemical, power, and water treatment. Existing gate valves are generally fixed in installation, which is relatively complex, and their sealing and corrosion resistance cannot be fully guaranteed under certain operating conditions. Especially in applications requiring frequent disassembly and maintenance, traditional gate valves often present difficulties in installation and disassembly, leading to a shortened equipment lifespan. Furthermore, some gate valves are prone to leakage or wear over long-term use, affecting their normal operation and thus posing a risk of pipeline leakage. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides an assembled gate valve, which aims to improve the problem of complex assembly steps in the existing gate valve technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an assembled gate valve, comprising a cross mounting tube, one-way valves uniformly and fixedly connected around the front side of the cross mounting tube, a gate valve body fixedly connected to the center of the front side of the cross mounting tube, sealing sleeves uniformly and fixedly connected around the outer side of the cross mounting tube, and an assembly assembly provided inside the cross mounting tube for quick assembly of the gate valve.

[0005] As a further description of the above technical solution:

[0006] The assembly component includes a threaded tube, which is threadedly connected inside a cross-shaped mounting tube. A threaded sleeve is fixedly connected to the end of the threaded tube away from the cross-shaped mounting tube. A connecting tube is threadedly connected to the lower inner side of the threaded sleeve. A pipe body is fixedly connected to the end of the connecting tube away from the threaded sleeve.

[0007] As a further description of the above technical solution:

[0008] The cross-shaped mounting tube is made of carbon steel, the sealing sleeve is made of polytetrafluoroethylene, and the bodies of the one-way valve and the gate valve are both made of stainless steel.

[0009] As a further description of the above technical solution:

[0010] The threaded pipe is made of stainless steel.

[0011] As a further description of the above technical solution:

[0012] The threaded sleeve is made of brass, and the connecting pipe is made of alloy steel.

[0013] As a further description of the above technical solution:

[0014] The pipe body is made of carbon steel.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, when the gate valve needs to be assembled, the cross mounting tube is pushed to move to the opposite side of the threaded sleeve, and the threaded sleeve is rotated to drive the threaded tube to move inside the cross mounting tube. The threaded tube drives the threaded sleeve to move so that it connects with the connecting tube, thereby making the gate valve easier to assemble and improving the practicality of the gate valve.

[0017] 2. In this utility model, the strength and pressure resistance of the cross mounting tube are ensured by using carbon steel, the elasticity, sealing performance and wear resistance of the sealing sleeve are improved by using polytetrafluoroethylene, and the wear resistance and corrosion resistance of the check valve and gate valve body are ensured by using stainless steel, thereby improving the service life of the assembled gate valve.

[0023] 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.

[0024] Reference Figures 1-3This utility model provides an embodiment of an assembled gate valve, comprising a cross mounting tube 1, with one-way valves 2 uniformly fixedly connected around the front perimeter of the cross mounting tube 1, a gate valve body 3 fixedly connected to the center of the front perimeter of the cross mounting tube 1, and sealing sleeves 4 uniformly fixedly connected to the outer perimeter of the cross mounting tube 1. An assembly assembly is provided inside the cross mounting tube 1 for quick assembly of the gate valve. The assembly assembly includes a threaded tube 5, which is threadedly connected inside the cross mounting tube 1. A threaded sleeve 6 is fixedly connected to the end of the threaded tube 5 away from the cross mounting tube 1, and a connecting tube 7 is threadedly connected to the inner lower part of the threaded sleeve 6. A pipe body 8 is fixedly connected to the end of the connecting tube 7 away from the threaded sleeve 6. The threaded tube 5 is made of stainless steel, the threaded sleeve 6 is made of brass, the connecting tube 7 is made of alloy steel, and the pipe body 8 is made of carbon steel.

[0025] When assembling a gate valve, first push the cross mounting tube 1 to move it smoothly to the side opposite the threaded sleeve 6. Then rotate the threaded sleeve 6, which in turn drives the threaded tube 5 to move inside the cross mounting tube 1. The threaded tube 5 further drives the threaded sleeve 6 to move, ultimately making the threaded sleeve 6 firmly connected to the connecting tube 7. This makes the assembly process of the gate valve simpler and more efficient, saving time and manpower, ensuring that all components can be accurately connected, thereby improving the accuracy and quality of the assembly, enhancing the practicality of the gate valve, enabling it to be installed and used more quickly and stably, meeting the needs of different working environments, and ensuring the efficient operation and long-term use of the device.

[0026] Reference Figures 1-3 The cross mounting tube 1 is made of carbon steel, the sealing sleeve 4 is made of polytetrafluoroethylene, and the check valve 2 and the gate valve body 3 are both made of stainless steel.

[0027] By using carbon steel to ensure the strength and pressure resistance of the cross mounting pipe 1, its stability and pressure resistance under high-intensity and high-pressure environments are guaranteed, thus enabling it to withstand greater workloads. By using polytetrafluoroethylene (PTFE) to improve the elasticity, sealing performance, and wear resistance of the sealing sleeve 4, leakage can be effectively prevented, ensuring sealing performance and long-term reliability. By using stainless steel to ensure the wear resistance and corrosion resistance of the check valve 2 and the gate valve body 3, it can resist the erosion of external corrosive media even in complex working environments, ensuring the long-term stable operation of the valve. This improves the service life of the assembled gate valve, enhances its overall reliability and adaptability, and can meet the needs of efficient operation for longer periods of time.

[0028] Working principle: When the gate valve needs to be assembled, push the cross mounting tube 1 to move it to the opposite side of the threaded sleeve 6, rotate the threaded sleeve 6 to drive the threaded tube 5 to move inside the cross mounting tube 1, and the threaded tube 5 drives the threaded sleeve 6 to move so that it connects with the connecting tube 7. This makes it easier to assemble the gate valve and improves the practicality of the gate valve.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
