Description

Technical Field

[0001] The invention relates to the technical field of stop valves, in particular to a stop valve that can be installed at any angle and a mounting method thereof. Background Art

[0002] The stop valve, also known as the gate valve, is a forced sealing valve. Therefore, when the valve is closed, pressure must be applied to the valve disc to force the sealing surface to prevent leakage. The stop valve also has the advantages of good sealing, small operating torque, and small fluid resistance, and is widely used in petroleum, chemical, water treatment and other industries.

[0003] For example, the announcement number is: CN215445068U (named as a piston-type stop valve that can be installed at any angle), which includes a valve body, a valve seat and a valve disc are arranged in the valve body, a valve cover is fixedly installed on the top of the valve body by bolts, a nut is threaded on the bolt, a stuffing box is welded on the top of the valve cover, a stuffing box is bolted to the stuffing box, the outer circle of the valve disc is very complete, and a valve stem is fixedly connected by a cylindrical pin, a handle is fixedly connected to the upper end of the valve stem, the handle vertically penetrates the stuffing box, and a handwheel is installed on the end, the cylindrical pin is mainly used for positioning and connection, can play a role in shear resistance, and should not be disassembled frequently, otherwise it will affect the positioning accuracy and the tightness of the connection. When the stop valve is in use, the valve stem and the valve disc are fixedly connected by a cylindrical pin, so that the two are completely fixed, and at the same time the valve stem drives the valve disc, so that the valve disc is reliably guided in the valve body. The valve stem and valve disc are fixed by the cylindrical pin, which changes the previous piston-type connection between the valve disc and the valve stem, and achieves complete fixation, which can prevent the valve disc and valve stem from falling off during the use of the stop valve; at the same time, the outer circle of the valve disc is very complete, which increases the strength of the valve disc and improves the service life of the valve disc. The retaining spring is a fastener used to limit the axial displacement of the parts and prevent the parts from being offset and loose. The retaining spring set on the outer surface of the valve seat allows the valve to be opened and closed reciprocatingly, thereby increasing the number of times the valve is opened and closed.

[0004] The above-mentioned stop valve is convenient for leakage-free installation at any angle by setting up a valve body sealing mechanism, but the valve body lacks an effective positioning and erecting mechanism during the installation process, resulting in the need for manual lifting and erection of the stop valve during the installation process, causing the problem of poor installation accuracy of the stop valve. For this reason, we provide a stop valve that can be installed at any angle and an installation method thereof. Summary of the invention

[0021] Preferably, the method for installing a stop valve that can be installed at any angle comprises the following steps:

[0022] Step 1: Adjust the inlet and outlet of the stop valve to the corresponding angles and directions according to the positions of the two pipes. Through the rotational connection of the integrated coupling and the bearing seat, the stainless steel valve body is rotated 360 degrees so that the stop valve can be rotated and adjusted to a suitable angle for installation;

[0023] Step 2: After adjusting to the required position, grab the handle rod and insert the positioning rod into the inside of the through hole, so that the positioning rod abuts against the outer edge disk, so that the positioning rod is adsorbed and connected to the outer edge disk through the magnet block, and the stop valve is positioned at the angle after rotation adjustment;

[0024] Step 3: Press the first switch, and the servo motor drives the threaded screw to rotate forward and reverse, so that the screw slider moves up and down along the inner slide groove, and then drives the stop valve to move up and down synchronously, so that the inlet and outlet move to the connection position of the two pipes;

[0026] Step 5: After the azimuth angle is adjusted, the inlet and outlet of the stop valve are sealed and connected to the two pipes through flanges. After the connection is completed, turn the hand wheel to make the valve disc away from the valve seat. The fluid enters from the inlet, passes through the valve seat and enters the impeller cavity, driving the small impeller to rotate, and is discharged through the outlet;

[0027] Step 6: The rotation of the small impeller drives the linkage shaft and the impeller coupling shaft of the impeller generator to rotate, so that the impeller generator generates electricity.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] (1) The present invention uses an integrated coupling shaft and a rotational connection with a bearing seat to adjust the stainless steel valve body by 360 degrees, so that the stop valve can be rotated and adjusted to a suitable angle for installation. The servo motor drives the threaded screw to rotate forward and reverse, so that the screw slider moves up and down along the inner slide groove, thereby driving the stop valve to move synchronously up and down, so that the inlet and outlet move to the connection position of the two pipes. The bottom connecting shaft and the bottom end plate are rotatably connected, so that the stop valve can be adjusted by 360 degrees with the track frame as the center of the circle. Finally, the inlet and outlet of the stop valve after the azimuth angle adjustment are sealed and connected to the two pipes through flanges, thereby improving the accuracy of the stop valve when installed at any angle, and overcoming the problem that the existing stop valve is easy to install at any angle without leakage by setting a valve body sealing mechanism, but the valve body lacks an effective positioning and erecting mechanism during the installation process, resulting in the need for manual lifting and erection of the stop valve during the installation process, resulting in poor installation accuracy of the stop valve.

[0030] (2) The fluid enters from the inlet, passes through the valve seat and enters the impeller cavity, driving the small impeller to rotate, and is discharged through the outlet. The rotation of the small impeller drives the linkage shaft and the impeller coupling shaft of the impeller generator to rotate, so that the impeller generator generates electricity. The generated electric energy is processed by the rectifier and the DC power is charged into the battery in the power box, so that the stop valve does not need an external power supply when installed at any angle, and uses the stop valve to guide the fluid to generate electricity, saving energy.

[0049] See also Figure 1-6 , a method for installing a stop valve that can be installed at any angle, comprising the following steps:

[0050] Step 1: Adjust the inlet 2 and outlet 3 of the stop valve to the corresponding angles and orientations according to the positions of the two pipelines, and rotate the stainless steel valve body 1 360 degrees through the rotation connection of the integrated coupling 25 and the bearing seat 26, so that the stop valve can be rotated and adjusted to a suitable angle for installation;

[0051] Step 2: After adjusting to the required position, grab the handle rod 16 and insert the positioning rod 22 into the inside of the through hole 21, so that the positioning rod 22 abuts against the outer edge disk 15, so that the positioning rod 22 is adsorbed and connected with the outer edge disk 15 through the magnet block 29, and the stop valve is positioned at the angle after rotation adjustment;

[0052] Step 3: Press the first switch 13, and the servo motor 10 drives the threaded screw 24 to rotate forward and reverse, so that the screw slider 31 moves up and down along the inner slide groove 30, thereby driving the stop valve to move up and down synchronously, so that the inlet 2 and the outlet 3 move to the connection position of the two pipes;

[0053] Step 4: Through the rotation connection between the bottom connecting shaft 17 and the bottom end plate 18, the stop valve is adjusted to 360 degrees with the track frame 9 as the center. After the steering is adjusted to the right position, the second switch 27 is pressed, so that the power box 8 supplies power to the electromagnet plate 39. After the electromagnet plate 39 is powered, it generates magnetic force to attract the limit shaft plate 40, and re-positions the position after the steering adjustment;

[0054] Step 5: After the azimuth angle is adjusted, the inlet 2 and outlet 3 of the stop valve are sealed and connected to two pipes through flanges. After the connection is completed, the hand wheel 6 is turned to make the valve disc 34 away from the valve seat 33. The fluid enters from the inlet 2, passes through the valve seat 33 and enters the impeller cavity 36, driving the small impeller 37 to rotate, and is discharged through the outlet 3;

[0055] Step 6: The small impeller 37 rotates to drive the linkage shaft of the impeller generator 11 and the impeller connecting shaft 20 to rotate, so that the impeller generator 11 generates electricity. The generated electric energy is processed by the rectifier 12 and the DC power is charged into the battery in the power box 8.

[0056] The valve seat and the stainless steel valve body are connected by threads, and a cone seal is used between the two. The sealing surface width of the valve body cone is controlled at 1-3mm, and the valve seat cone width is three times the cone width of the valve body.

[0057] (1) Line sealing can be achieved, that is, the initial design width of the valve seat cone surface is 0.5-1mm. The sealing pressure of the line seal is smaller than that of the plane or other forms of sealing surface, which is easy to meet the designed sealing requirements. The operating torque of the line seal is also the smallest.

[0058] (2) The conical sealing surface can realize the function of "automatic alignment", that is, when the valve disc cannot fall smoothly on the valve seat sealing surface due to factors such as the flow medium or the installation position, the conical surfaces can automatically match and find the appropriate sealing position as quickly as possible.

[0059] (3) When the valve is used for a long time, the conical surface of the valve seat will be squeezed or worn by the conical surface of the valve disc, and the width of the conical surface will gradually widen. At this time, the valve sealing can be easily achieved by increasing the closing torque without causing the valve sealing to fail.

[0060] (4) When the valve disc is separated from the valve seat sealing surface, the separation time of the conical seal pair is the shortest, thus avoiding the long-term relative friction movement between the seal pairs, which may cause rapid wear or abrasion failure of the seal pair.

[0061] In summary, the stop valve can ensure sealing performance when installed at any angle.

[0062] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

10. The method for installing a stop valve that can be installed at any angle according to claim 9, characterized in that: The following steps are involved: Step 1: According to the positions of the two pipelines, the inlet (2) and outlet (3) of the stop valve are adjusted to corresponding angles and orientations, and the stainless steel valve body (1) is rotated 360 degrees through the rotation connection of the integrated coupling (25) and the bearing seat (26), so that the stop valve can be rotated and adjusted to a suitable angle for installation; Step 2: After adjusting to the required position, grab the handle rod (16) and insert the positioning rod (22) into the inside of the through hole (21), so that the positioning rod (22) abuts against the outer edge disk (15), so that the positioning rod (22) is adsorbed and connected with the outer edge disk (15) through the magnet block (29), and the stop valve is positioned at the angle after rotation adjustment; Step 3: Press the first switch (13), and the servo motor (10) drives the threaded screw (24) to rotate forward and reverse, so that the screw slider (31) moves up and down along the inner slide groove (30), thereby driving the stop valve to move up and down synchronously, so that the inlet (2) and the outlet (3) move to the connection position of the two pipes; Step 4: The bottom connecting shaft (17) is connected to the bottom end plate (18) by rotation, so that the stop valve can be adjusted 360 degrees with the track frame (9) as the center. After the steering is adjusted to the right position, the second switch (27) is pressed, so that the power box (8) supplies power to the electromagnet plate (39). After the electromagnet plate (39) is powered, it generates magnetic force to attract the limit shaft plate (40) to re-position the position after the steering adjustment. Step 5: After the azimuth angle adjustment is completed, the inlet (2) and outlet (3) of the stop valve are sealed and connected to two pipes through flanges. After the connection is completed, the hand wheel (6) is turned to make the valve disc (34) away from the valve seat (33). The fluid enters from the inlet (2), passes through the valve seat (33) and enters the impeller chamber (36), drives the small impeller (37) to rotate, and is discharged through the outlet (3); Step 6: The small impeller (37) rotates to drive the linkage shaft of the impeller generator (11) and the impeller connecting shaft (20) to rotate, so that the impeller generator (11) generates electricity. The generated electric energy is processed by the rectifier (12) and the direct current is charged into the battery in the power box (8).
