Description

Technical Field

[0001] This utility model relates to an instrument valve alignment device for the rapid alignment and installation of instrument valves. Background Technology

[0002] For the installation of instrument valves in thermal control, it is necessary to first align and connect the instrument valves. After alignment, the instrument valves are welded together. There are many large-diameter (DN50) instrument valves for measuring the liquid level in the heater, and each valve is quite heavy. The heater has a connecting pipe that extends outward to connect with the instrument valve. During installation, a hand hoist is first used to lift the instrument valve to the height of the connecting pipe, and then the instrument valve and the connecting pipe are aligned and connected. Due to the heavy weight of the instrument valve, the instrument valve is prone to shaking when lifted by the hand hoist. During the alignment process, two people are needed to hold the instrument valve. Alignment is time-consuming, prone to misalignment, resulting in low installation efficiency and easy rework due to misalignment. Utility Model Content

[0003] The instrument valve alignment device provided by this utility model enables the interface of the instrument valve to be quickly aligned with the connecting pipe and form a joint, avoiding the instrument valve from shaking during alignment, improving the accuracy of alignment, effectively reducing the misalignment rate, and shortening the time required for alignment, thereby improving the installation efficiency of the instrument valve. Only one person needs to push the instrument valve forward to complete the alignment, reducing the labor intensity during instrument valve installation, improving the operational standardization of instrument valve installation, and achieving standardized, efficient, and accurate instrument valve installation.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An instrument valve alignment device, characterized in that: it includes an upper clamping plate, a lower clamping plate arranged parallel to the lower part of the upper clamping plate, and a bolt assembly connecting the upper clamping plate and the lower clamping plate. The cross-section of the upper clamping plate is a downwardly flared V-shape, and the cross-section of the lower clamping plate is an upwardly flared V-shape. The upper clamping plate and the lower clamping plate are arranged opposite to each other and are spaced apart and do not contact each other. The length of the upper clamping plate is shorter than that of the lower clamping plate. The front end of the upper clamping plate is aligned with the front end of the lower clamping plate. The upper clamping plate and the lower clamping plate move closer together as the bolt assembly is tightened.

[0005] Preferably, the bolt assembly includes upper nuts welded to the left and right sides of the upper clamping plate, lower nuts welded to the left and right sides of the lower clamping plate, and a bolt that is threaded to both the upper and lower nuts, and bolts the upper nuts and the lower nuts that are aligned with the upper nuts.

[0006] Preferably, there are two upper nuts, one near the front end of the upper clamping plate and the other near the rear end of the upper clamping plate, and two lower nuts, each aligned with one of the upper nuts.

[0007] Preferably, the lower clamping plate consists of a clamping section opposite to the upper clamping plate and a support section integrally formed with the clamping section. The lower nut is welded to the left and right sides of the clamping section. The front end of the upper clamping plate is aligned with the front end of the clamping section. The length of the upper clamping plate is equal to that of the clamping section and is 80~100mm. The length of the support section is two to three times that of the clamping section.

[0008] Preferably, it also includes a height adjustment pad placed on the clamping section. The pad is a V-shaped plate that fits into the clamping section. The upper clamping plate, the lower clamping plate, and the height adjustment pad are all angle iron.

[0009] The beneficial effects of this utility model are: This utility model discloses an instrument valve alignment device. An upper clamping plate and a lower clamping plate are arranged opposite each other with their front ends aligned. The length of the lower clamping plate is greater than the length of the upper clamping plate. Before installing the instrument valve, the connecting pipe to be connected to the instrument valve is clamped between the upper and lower clamping plates. The bolt assembly is tightened to bring the upper and lower clamping plates close together and clamp them onto the connecting pipe. Next, the instrument valve is placed on the lower clamping plate, and the instrument valve is pushed forward along the lower clamping plate to allow the connecting pipe to extend into the instrument valve's interface, forming a quick alignment between the connecting pipe and the instrument valve. Finally, the interface of the instrument valve is welded to the connecting pipe to complete the instrument valve alignment. During valve installation, the lower clamping plate not only works with the upper clamping plate to clamp the connecting pipe, but also provides support and guidance for the instrument valve. This allows the instrument valve interface to be quickly aligned with the connecting pipe, preventing the instrument valve from shaking during alignment, improving alignment accuracy, effectively reducing misalignment rate, and shortening the alignment time. This increases installation efficiency, requiring only one person to push the instrument valve forward to complete alignment, reducing labor intensity during installation, improving operational standardization, and achieving standardized, efficient, and accurate instrument valve installation.

[0013] The following is combined Figures 1-3 The embodiments of this utility model will be described in detail below.

[0014] An instrument valve alignment device, characterized in that: it includes an upper clamping plate 1, a lower clamping plate 2 arranged parallel below the upper clamping plate 1, and a bolt assembly 3 connecting the upper clamping plate 1 and the lower clamping plate 2. The cross-section of the upper clamping plate 1 is a downwardly flared V-shape, and the cross-section of the lower clamping plate 2 is an upwardly flared V-shape. The upper clamping plate 1 and the lower clamping plate 2 are arranged opposite to each other and spaced apart from each other without contact. The length of the upper clamping plate 1 is shorter than that of the lower clamping plate 2. The front end of the upper clamping plate 1 is aligned with the front end of the lower clamping plate 2. The upper clamping plate 1 and the lower clamping plate 2 move closer together as the bolt assembly 3 is tightened.

[0015] The instrument valve alignment device described above has an upper clamping plate 1 and a lower clamping plate 2 positioned opposite each other with their front ends aligned. The length of the lower clamping plate 2 is greater than the length of the upper clamping plate 1. Before installing the instrument valve, the connecting pipe 100 that will connect to the instrument valve is clamped between the upper clamping plate 1 and the lower clamping plate 2. The bolt assembly 3 is tightened to bring the upper clamping plate 1 and the lower clamping plate 3 close together and clamp them onto the connecting pipe 100. Then, the instrument valve 101 is placed on the lower clamping plate 2, and the instrument valve is pushed forward along the lower clamping plate 2 to allow the connecting pipe 100 to extend into the interface of the instrument valve 101, forming a quick alignment between the connecting pipe 100 and the instrument valve 101. Finally, the interface of the instrument valve 101 is connected to the connecting pipe 101. After the pipe 100 is welded and the instrument valve is installed, the lower clamping plate 2 not only cooperates with the upper clamping plate 1 to clamp onto the connecting pipe 100, but also provides support and guidance for the instrument valve 101. This allows the interface of the instrument valve 101 to be quickly aligned with the connecting pipe 100 and form a joint, preventing the instrument valve 101 from shaking during alignment, improving the accuracy of alignment, effectively reducing the misalignment rate, and shortening the time required for alignment. This increases the installation efficiency of the instrument valve, requiring only one person to push the instrument valve forward to complete the alignment, reducing the labor intensity during installation, improving the operational standardization of instrument valve installation, and achieving standardized, efficient, and accurate instrument valve installation.

[0016] The bolt assembly 3 includes upper nuts 4 welded to the left and right sides of the upper clamping plate 1, lower nuts 5 welded to the left and right sides of the lower clamping plate 2, and a screw 6 threaded to both the upper and lower nuts. The screw 6 connects the upper nuts 4 and the lower nuts 5 aligned with the upper nuts 4. As shown in the figure, upper nuts 4 are welded to the left and right sides of the upper clamping plate 1, and lower nuts 5 are welded to the left and right sides of the lower clamping plate 2. The screw 6 is screwed into the upper nuts 4 and the lower nuts 5 aligned with the upper nuts 4. When the screw 6 is tightened, the upper clamping plate 1 and the lower clamping plate 2 move closer together, clamping the connecting pipe 100 located between the upper and lower clamping plates, so that the upper and lower clamping plates are positioned on the connecting pipe 100. When the screw 6 is loosened, the upper and lower clamping plates can be removed from the connecting pipe 100.

[0017] The upper nut 4 consists of two nuts, one near the front end of the upper clamping plate 1 and the other near the rear end. The lower nuts 5 are also two, each aligned with one of the upper nuts 4. The two upper nuts 4 on the upper clamping plate 1 are staggered, one near the front end and the other near the rear end. Similarly, the two lower nuts 5 are staggered and aligned with the upper nuts 4. This arrangement ensures that both the front and rear ends of the upper clamping plate 1 are clamped to the connecting pipe 100 via bolt assemblies 3. This improves both the clamping reliability and the positioning reliability of the lower clamping plate 2, preventing the lower clamping plate 2 from tilting due to load when the instrument valve is placed on it, thus ensuring accurate alignment.

[0018] The lower clamping plate 2 is composed of a clamping section 21 opposite to the upper clamping plate 1 and a support section 22 integrally formed with the clamping section 21. The lower nut 5 is welded to the left and right sides of the clamping section 21. The front end of the upper clamping plate 1 is aligned with the front end of the clamping section 21. The length of the upper clamping plate 1 is equal to that of the clamping section 21 and is 80~100mm. The length of the support section 22 is two to three times that of the clamping section 21. The clamping section 21 is used to cooperate with the upper clamping plate 1 to clamp the connecting pipe 100, while the supporting section 22 is used to support the instrument valve 101. After the upper clamping plate 1 and the lower clamping plate 2 are clamped on the connecting pipe 100, the instrument valve 101 is placed on the supporting section 22, and the instrument valve 101 is pushed forward along the supporting section 22 so that the connecting pipe 100 extends into the interface of the instrument valve 101, so as to achieve quick alignment. The length of the upper clamping plate 1 should be adapted to the length of the connecting pipe 100, and the length of the supporting section 22 should be adapted to the length of the instrument valve 100, so that the instrument valve 101 can be effectively supported by the supporting section 22.

[0019] This includes height adjustment shims placed on the clamping section 21. Shim 7 is a V-shaped plate that fits snugly against the clamping section 21. The upper clamping plate 1, lower clamping plate 2, and height adjustment shims 7 are all angle iron. Angle iron is low in cost and easy to obtain locally on the construction site. Due to the large thickness of the instrument valve body, when the instrument valve is placed on the support plate 22, the height of the interface of the instrument valve 101 may be higher than the height of the connecting pipe 101, resulting in a height difference that cannot be aligned. The height adjustment shims 7 are added to the clamping plate 21 to compensate for the height difference between the connecting pipe and the instrument valve interface, so that the interface of the instrument valve can be accurately aligned with the connecting pipe when placed on the support section 22. The thickness and number of height adjustment shims 7 placed on the clamping section 21 should be calculated based on the thickness of the valve body of the instrument valve to be installed and the thickness of the connecting pipe to ensure the accuracy of the alignment of the instrument valve.
