[0002] A duplex horizontal cooler is a highly efficient heat exchange device widely used in a variety of industries, including chemical, pharmaceutical, food processing, power, and metallurgy. It primarily consists of two shell-and-tube coolers of equal size. The cooler ends are sealed with end caps to form flow channels. The cooler interior consists of a tube bundle and a tube sheet connecting the bundles. The two shell-and-tube coolers are connected by a three-way valve.

[0003] The three-way valve controls the flow of liquid within the housing. During use, manual rotation of the valve stem is required to change the direction of the valve core. This process presents the following issues: Separately controlling the two three-way valves is cumbersome. Utility Model Content

[0016] In one embodiment of the present application, there are two support mechanisms, one on each side of the handle. The beneficial effect of this step is that the deformation resistance of the connecting rod is improved through double-point support.

[0030] In this application, unless otherwise specified or limited, the terms used in this application should be understood broadly. For example, a connection can be a fixed connection, a detachable connection, or an integral connection. It can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of different terms in this utility model can be understood according to specific circumstances. The scope of the specific meanings should be limited to achieving the functions of this application.

[0031] Example 1

[0032] like Figure 1 As shown, a three-way valve synchronous control device includes: a connecting rod 1, a supporting mechanism 2, and a handle 3. The two ends of the connecting rod 1 are respectively connected to the valve stem 401 of the corresponding three-way valve 4. The supporting mechanism 2 includes: a mounting seat 201, a first connecting member 202, and a support sleeve 203. The mounting seat 201 is connected to the shell 5 of the cooler. The first connecting member 202 is height-adjustable and connected to the mounting seat 201. The support sleeve 203 is connected to the first connecting member 202. The connecting rod 1 is rotatably inserted in the support sleeve 203. The handle 3 is connected to the connecting rod 1. The handle 3 is used to drive the connecting rod 1 to rotate.

[0033] Specifically, such as Figure 1 As shown, the connecting rod 1 is arranged horizontally and comprises a hollow rod and a connecting block. The connecting block is welded to both ends of the hollow rod. The connecting block has a matching plug-in hole corresponding to the square valve stem 401, and the valve stem 401 is inserted into the plug-in hole. The plug-in connection structure facilitates the connection between the valve stem 401 and the connecting rod 1.

[0034] Specifically, such as Figure 1 As shown, a three-way valve synchronous control device is provided, wherein the handle 3 is sleeved on the middle position of the connecting rod 1 and is welded to the connecting rod 1.

[0035] Specifically, such as Figure 1As shown, the three-way valve synchronous control device further includes: a second connecting member 6, which fixes the connecting rod 1 to the valve stem 401. The second connecting member 6 is exemplified as follows: the second connecting member 6 can be a bolt or a nut, which passes through the through-holes formed in the connecting block and the valve stem 401 and is connected to the nut, thereby fixing the valve stem 401 to the connecting rod 1; in addition, the second connecting member 6 can also be a pin or a cotter pin, the middle portion of which passes through the through-holes formed in the connecting block and the valve stem 401, and a cotter pin is inserted into the through-hole at the end of the pin exposed to the outside, thereby fixing the valve stem 401 to the connecting rod 1 through the pin, and preventing the pin from falling out of the connection structure by the cotter pin.

[0036] Specifically, such as Figure 1 As shown, there are two support mechanisms 2, one on each side of the handle 3. Since the connecting rod 1 is a long hollow rod, it is easily deformed by stress. If the connecting rod 1 bends, it can be difficult to use smoothly or completely unusable. To prevent this, two support points are added to the middle of the connecting rod 1, which is equivalent to shortening the length of a single section of the connecting rod 1, thereby improving the connecting rod 1's resistance to bending and deformation. Furthermore, the support mechanism 2 also serves as a support structure between the two shells 5, improving the stability of the structure when the shells 5 are connected in parallel.

[0037] Specifically, such as Figure 1 As shown, each support mechanism 2 includes two mounting seats 201 , each shell 5 is correspondingly connected to a mounting seat 201 , each mounting seat 201 is connected to a first connecting member 202 , and a support sleeve 203 is connected between the first connecting members 202 .

[0038] Specifically, such as Figure 1 As shown, the first connecting member 202 includes a screw and a nut. The screw is inserted into a hole defined in the mounting base 201. The support sleeve 203 is connected to the screw, and the nut connects the screw to the mounting base 201. Mounting base 201 is equipped with a connecting plate corresponding to the screw. The connecting plate has a through hole, through which the screw passes. Nuts are provided on both the upper and lower sides of the connecting plate, which are threadedly connected to the screw. The nuts are tightened to secure the connecting rod in place. The connection between the nut and the screw allows for adjustable screw connection height, which improves the ease of assembly between the support mechanism 2 and the connecting rod 1.

[0039] When this three-way valve synchronous control device is in use, the handle 3 is manually pulled to rotate the valve stem 401 to achieve synchronous action of the three-way valves 4 on both sides, saving the steps of manual operation and reducing the complexity of manual operation; a support mechanism 2 is provided, which can, on the one hand, provide support between the two parallel coolers, and on the other hand, can also support the connecting rod 1, thereby improving the structural strength and anti-deformation ability of the connecting rod 1.

[0040] Example 2

[0041] The difference between the second embodiment and the first embodiment is that Figure 2 As shown, the support mechanism 2 further includes: a guide sleeve 7, the guide sleeve 7 is installed on the mounting seat 201, and the connecting rod 1 is rotatably inserted into the guide hole opened by the guide sleeve 7.

[0042] Specifically, the guide sleeve 7 adopts a self-lubricating copper sleeve, and one end of the guide sleeve 7 is provided with a flange, which is connected to the mounting seat 201 by bolts. By providing the guide sleeve 7, the smoothness of the rotation of the connecting rod 1 is improved, and later maintenance operations are also facilitated.
