Description

Technical Field

[0001] The utility model relates to the technical field of pressure reducing valves, in particular to a pressure reducing valve which is easy to fix. Background Art

[0002] The pressure reducing valve is a device that controls flow. By adjusting the pressure reducing valve, the inlet pressure is reduced to a required outlet pressure. It is also a valve that can automatically maintain stability.

[0003] The existing pressure reducing valve has a problem that the fixed pipe and other pipes are fixed by screws, and the screws are prone to loosening in daily use;

[0004] The reason for this problem is that the pressure reducing valve is fixedly connected to other pipes through a fixed pipe. In order to facilitate the fixation of other pipes to the outer surface of the fixed pipe, screws are used to install them to the end positions of the fixed pipe and other pipes. The screws will become loose under the influence of external vibrations and other environmental factors, and the internal pressure of the pressure reducing valve is relatively high. If the screws become loose, a gap will be generated at the connection position between the pressure reducing valve connecting pipe and other pipes, which will cause leakage. Therefore, we propose a pressure reducing valve that is easy to fix. Utility Model Content

[0029] The utility model embodiment discloses a pressure reducing valve which is easy to fix.

[0030] According to the attached Figure 1-6As shown, it includes a pressure reducing valve body 1, a fixing tube 101 is arranged on the outer surface of the pressure reducing valve body 1, a screw 102 is arranged inside the fixing tube 101, a limiting plate 2 is arranged on the outer surface of the fixing tube 101, a limiting mechanism for preventing the screw 102 from loosening is arranged on the outer surface of the limiting plate 2, the limiting mechanism includes a spring 201 arranged on the outer surface of the limiting plate 2, a clamping plate 202 is arranged on the outer surface of the limiting plate 2, and the clamping plate 202 is movably clamped on the outer surface of the screw 102.

[0031] By pushing the sleeve tube 204, the sleeve tube 204 will drive the limit plate 2 to slide on the outer surface of the connecting tube 103. The outer surface of the connecting tube 103 is sleeved with the limit ring 213. The outer surface of the limit plate 2 is against the outer surface of the limit ring 213. At the same time, the sleeve tube 204 will drive the push plate 205 to move. The push plate 205 will squeeze the spring 201 and the telescopic tube 207. At the same time, the sleeve tube 204 will drive the limit plate 2 to leave the outer surface of the fixed tube 101, and the clamping plate 202 will leave the inside of the movable groove 208 as the limit plate 2 moves.

[0032] A connecting pipe 103 is provided on the outer surface of the pressure reducing valve body 1, and the fixed pipe 101 is fixedly connected to the outer surface of the connecting pipe 103. A movable groove 208 is opened on the outer surface of the fixed pipe 101, and the screw member 102 is arranged inside the movable groove 208. The end of the screw member 102 is fixedly connected with a connecting end 203, and the connecting end 203 is arranged inside the movable groove 208. The clamping plate 202 is movably inserted into the inside of the movable groove 208, and the clamping plate 202 is movably clamped on the outer surface of the connecting end 203.

[0033] The outer surface of the connecting tube 103 is sleeved with a connecting plate 206, the spring 201 is fixedly connected to the outer surface of the connecting plate 206, the outer surface of the connecting plate 206 is fixedly connected with a telescopic plate 209, the outer surface of the telescopic plate 209 is fixedly connected with a support plate 210, the outer surface of the support plate 210 is fixedly connected with a limiting block 211, the outer surface of the limiting plate 2 is fixedly connected with a sleeve tube 204, the sleeve tube 204 is movably sleeved on the outer surface of the connecting tube 103, and the outer surface of the sleeve tube 204 is fixedly connected with a push plate 205, the spring 201 is fixedly connected to the outer surface of the push plate 205, and the outer surface of the push plate 205 is fixedly connected with a telescopic tube 207, and the other end of the telescopic tube 207 is fixedly connected to the outer surface of the connecting plate 206, and the telescopic tube 207 is movably sleeved on the outer surface of the spring 201. By setting the limiting plate 2 and the clamping plate 202, the clamping plate 202 is movably sleeved on the outer surface of the connecting end 203, so that the position of the screw 102 is limited to prevent the screw 102 from loosening during daily use.

[0034] By pushing the sleeve tube 204, the clamping plate 202 is moved out from the inside of the movable groove 208, and then the screw 102 passes through the movable groove 208 and is installed in the inside of the fixed tube 101. At this time, the position of the connecting end 203 will be inside the movable groove 208. Then loosen the sleeve tube 204. At this time, the spring 201 will lose the extrusion force and generate tension. Under the action of the tension of the spring 201, the pushing plate 205 is pushed to move, and the pushing plate 205 will drive the sleeve tube 204 and the limiting plate 2 to move until the clamping plate 202 is movably clamped on the outer surface of the connecting end 203, and the clamping plate 202 is movably inserted into the inside of the movable groove 208.

By sliding the push plate 205, the push plate 205 will slide on the outer surface of the connecting tube 103, and then the position of the support plate 210 is moved, so that the support plate 210 drives the telescopic plate 209 to be telescoped, until the stop block 212 moves to a position close to the connecting plate 206, and then the limit block 211 is moved to make the outer surface of the limit block 211 abut against the side of the stop block 212 facing the limit plate 2, so that the position of the sleeve tube 204 after moving can be limited, which is convenient for installing the screw 102 inside the fixed tube 101.

[0036] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0037] By pushing the sleeve 204, the clamping plate 202 is moved out from the inside of the movable groove 208, and then the screw 102 passes through the movable groove 208 and is installed in the inside of the fixed tube 101, and then the sleeve 204 is loosened. At this time, the spring 201 will lose the extrusion force and generate tension. Under the action of the tension of the spring 201, the pushing plate 205 is pushed to move until the clamping plate 202 is movably clamped on the outer surface of the connecting end 203. In this way, by setting the limiting plate 2 and the clamping plate 202, the clamping plate 202 is movably sleeved on the outer surface of the connecting end 203, so as to limit the position of the screw 102 and prevent the screw 102 from loosening during daily use.
