Description

Technical Field

[0001] The utility model belongs to the technical field of valves, and in particular relates to a valve that is easy to connect. Background Art

[0002] A valve is a device used to control the direction, pressure, and flow of fluids in a fluid system. Valves enable or stop the flow of media (liquids, gases, powders) within piping and equipment, and can control their flow. Valves can be used to control the flow of various fluids, including air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media. Valves are control components in pipeline fluid transportation systems, used to change the cross-section of the passage and the direction of the medium's flow. They perform functions such as diversion, shutoff, throttling, check, diversion, or overflow pressure relief.

[0003] Currently, when connecting a valve to a pipeline, the inlet and outlet of the valve are butted against the pipeline through flanges, and then the two are fastened together using bolts and nuts. Although this method can effectively connect the valve to the pipeline, in temporary and emergency situations, this connection method is not only inefficient, but also has the problem of being unable to connect due to lack of bolts or nuts. Utility Model Content

[0008] Furthermore, a circle of grooves is respectively provided on the flange surfaces at the inlet and outlet of the valve, and a sealing ring is provided in the groove.

[0009] Furthermore, the cross section of the first connecting rod is L-shaped; the vertical connecting rod movable end of the first connecting rod is connected to the flange surface of the valve through the hinge seat, and the second connecting rod is arranged on the horizontal connecting rod of the first connecting rod.

[0010] Furthermore, the hinge port in the hinge seat is an oblong hole.

[0011] Furthermore, the inner side surface of the vertical connecting rod of the first connecting rod is provided with anti-slip grooves.

[0012] Furthermore, the transverse connecting rod of the first connecting rod passes through the second connecting rod, and the second connecting rod can slide on the transverse connecting rod of the first connecting rod, and a limiting mechanism is provided between the transverse connecting rod of the first connecting rod and the second connecting rod, and the limiting mechanism can block the second connecting rod from sliding toward the movable end of the transverse connecting rod of the first connecting rod; a limiting block is provided at the movable end of the transverse connecting rod of the first connecting rod.

[0013] Furthermore, the limiting mechanism includes a plurality of positioning blocks arranged on the first connecting rod and the transverse connecting rod, and a limiting rod and a spring arranged on the second connecting rod.

[0029] For further information, see Figure 2-3As shown, in this embodiment, the cross-section of the first connecting rod 21 is L-shaped; when connected, the movable end of the vertical connecting rod of the first connecting rod 21 is connected to the flange surface of the valve 1 through the hinge seat 22, and the second connecting rod 23 is arranged on the horizontal connecting rod of the first connecting rod 21. At this time, the second connecting rod 23 is parallel to the vertical connecting rod of the first connecting rod 21.

[0030] Among them, see Figure 1-2 As shown, in this embodiment, the hinge interface in the hinge seat 22 adopts an oblong hole, so that the first connecting rod 21 can rotate in the hinge seat 22 and displace on the hinge seat 22 at the same time, so that when connected, the inner side surface of the vertical connecting rod of the first connecting rod 21 fits with the valve 1, and in this embodiment, the inner side surface of the vertical connecting rod of the first connecting rod 21 is provided with an anti-slip groove 211.

[0031] In addition, see Figure 2 As shown, in this embodiment, the transverse connecting rod of the first connecting rod 21 passes through the second connecting rod 23, and the second connecting rod 23 can slide on the transverse connecting rod of the first connecting rod 21, and a limiting mechanism 25 is provided between the transverse connecting rod of the first connecting rod 21 and the second connecting rod 23, and a limiting block 26 is provided at the movable end of the transverse connecting rod of the first connecting rod 21; wherein, see Figure 3-4 As shown, the limiting mechanism 25 includes 11 groups of positioning blocks 251 provided on the first connecting rod 21 and the limiting rod 252 and the spring 253 provided on the second connecting rod 23. The number of the positioning blocks 251 is not limited to 11 groups, and other groups can also be provided. The cross-section of the positioning blocks 251 is in the shape of a right triangle, and the hypotenuse faces the movable end of the first connecting rod 21 and the transverse connecting rod, and the lower end of the limiting rod 252 is provided with an oblique angle, and the oblique angle is opposite to the hypotenuse of the positioning block 251, and the two have the same inclination angle; when installing, refer to Figure 2-4As shown, an avoidance groove 212 is provided on the upper end surface of the transverse connecting rod of the first connecting rod 21, and the positioning blocks 251 are all arranged at the bottom of the avoidance groove 212, and the positioning blocks 251 are linearly and evenly distributed at the bottom of the avoidance groove 212, and a mounting groove 231 is provided on the second connecting rod 23, and a cover 232 is provided at the upper end of the mounting groove 231, and the limiting rod 252 and the spring 253 are both provided in the mounting groove 231, wherein the lower end of the limiting rod 252 extends from the lower end of the mounting groove 231 and extends into the avoidance groove 212, and the upper end of the limiting rod 252 is extended from the cover 232 The spring 253 is sleeved in the limiting rod 252, and the lower end of the spring 253 is connected to the limiting rod 252 in an offset manner, and the upper end of the spring 253 is also connected to the cover 232 in an offset manner.

The sealing ring 3 is bonded to the bottom surface of the groove by glue, which can effectively prevent the sealing ring 3 from falling off from the groove and facilitate the replacement of the sealing ring 3.

[0035] The working principle of this utility model is as follows:

[0036] When connecting to a pipeline, align the flange surfaces at the inlet and outlet of the valve 1 with the flange surface of the pipeline, then rotate the first connecting rod 21 so that the horizontal connecting rod of the first connecting rod 21 spans between the flange surface of the valve 1 and the flange surface of the pipeline. At this time, the second connecting rod 23 and the locking rod 24 are located on the pipeline side; then push the second connecting rod 23 toward its horizontal connecting rod fixed end (connected to its vertical connecting rod end) until the locking block 4 contacts the pipeline flange surface and stops. Then, use a wrench to rotate the locking rod 24 until it is tightened. When it is necessary to release the connection with the pipeline, pull the lifting ring 5 upward and push it toward the movable end of the horizontal connecting rod of the second connecting rod 23 until the second connecting rod 23 stops against the limit block 26.
