Description

Technical Field

[0001] The utility model relates to the technical field of data collector equipment, in particular to a gas pipe network data collector. Background Art

[0002] The gas pipeline network refers to the system consisting of all facilities from the gate station to the user, including the gate station or gas source plant compressor station, gas storage facilities, pressure regulating devices, transmission and distribution pipelines, metering devices, management facilities and monitoring systems. During the operation of the gas pipeline network, it is necessary to measure the gas pressure and temperature in the pipeline in real time.

[0003] The data collection of gas pipelines includes data such as gas flow, pressure, temperature, etc. Gas pipelines are connected through flanges, and the data collector used to collect gas flow is also called a gas flow meter. In order to adapt to the gas pipeline for connection, the same flange is usually set on the outside of the gas flow meter, and then the gas flow meter and the gas pipeline are connected to each other through screws and nuts. Common flanges usually require six screws and nuts to cooperate with each other for fixing. The six screws and nuts not only need to provide lateral pressure to make the gas flow meter and the flange fit tightly together, but also need to bear the weight of the gas flow meter and the gas pipeline. Therefore, when connecting with the flange, enough screws and nuts are required to cooperate. In the process of tightening the screws and nuts, the nuts need to be fixed while tightening the screws to avoid the situation where the nuts rotate with the screws during the tightening process;

[0004] In the above situation, the connection and fixation between the flanges is troublesome and inconvenient to disassemble, so a gas pipe network data collector is proposed to solve the above problems. Utility Model Content

[0005] Based on the above description, the utility model provides a gas pipe network data collector to solve the problem that the existing gas flow meter is relatively cumbersome when the flange is connected by screws and nuts.

[0006] The utility model provides a technical solution to the above-mentioned technical problems as follows: a gas pipeline network data collector, comprising: a flow meter body, the flow meter body comprising a force plate, an installation groove, a positioning column and an installation ear, an annular clamp block is arranged at both ends of the flow meter body by a hinge screw, and a sealing ring is arranged inside the installation groove.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the flow meter body includes a main pipe, both ends of the main pipe are provided with force-bearing disks, and the main pipe and the force-bearing disk are connected to each other.

[0009] Furthermore, the inner wall of the force-bearing disk is provided with mounting grooves and positioning columns, and the positioning columns are distributed equidistantly in a ring shape.

[0010] Furthermore, the outer surface of the force-bearing disk is provided with a mounting ear, and the surface of the mounting ear is provided with a threaded hole.

[0011] Furthermore, the annular clamping block includes a first semicircular ring and a second semicircular ring, the first semicircular ring and the second semicircular ring form a complete annular block, and the inner diameter of the annular block is smaller than the inner diameter of the side of the force-bearing disk away from the main pipe.

[0012] Furthermore, both sides of the first semicircular ring and the second semicircular ring are provided with hinge ears, and the surfaces of the hinge ears are provided with hinge holes.

[0013] Furthermore, the hinge screw comprises a hexagonal block, and a cylindrical block and a threaded column are sequentially arranged at one end of the hexagonal block close to the flow meter body.

[0014] Furthermore, the threaded column is threadedly connected to the threaded hole, the cylindrical block extends to the inside of the hinge hole, and the diameter of the hexagonal block is larger than the inner diameter of the hinge hole.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0016] 1. This new type of device is equipped with a force plate, a positioning column and other components. The positioning column cooperates with the flange, that is, the positioning column is inserted into the hole on the surface of the flange. In this process, the positioning column not only plays a positioning role, but also can support the flange of the gas pipeline. The setting of the force plate can also play a supporting role when the flange is placed therein, thereby ensuring that there is a sufficiently large vertical supporting force between the gas pipeline and the flow meter;

[0017] 2. By setting the annular clamp and the hinge screw, the effect of connecting the annular clamp and the flow meter body is achieved, so that after the flange is inserted into the force-bearing plate, the side of the flange away from the main pipe can be squeezed by the annular clamp by tightening the hinge screw, thereby achieving the effect of connecting and fixing the gas pipeline and the flow meter body.

[0029] See also Figure 1-Figure 3 , a gas pipe network data collector, comprising:

[0030] The flow meter body 1 includes a force bearing plate 12, a mounting groove 13, a positioning column 14 and a mounting ear 15;

[0031] The flow meter body 1 includes a main pipe 11, both ends of the main pipe 11 are provided with a force plate 12, the main pipe 11 and the force plate 12 are connected to each other, the inner wall of the force plate 12 is provided with a mounting groove 13 and a positioning column 14, the positioning column 14 is distributed in an annular shape and equidistantly, the outer surface of the force plate 12 is provided with a mounting ear 15, and the surface of the mounting ear 15 is provided with a threaded hole 16;

[0032] A sealing ring 4, which is arranged inside the mounting groove 13;

[0033] Based on the above, when the flange of the gas pipeline extends into the interior of the force-bearing disk 12, the force-bearing disk 12 and the flange cooperate with each other to support each other, and after the positioning column 14 is inserted into the hole on the surface of the flange, it not only plays a positioning role, but also can provide supporting force. The two structures support at the same time, and the supporting effect is better than that of only screws. The installation groove 13 plays the role of installing the sealing peg 4, so that the flow meter body 1 and the gas pipeline have sufficient sealing after being connected to each other.

[0034] like Figure 1 and Figure 4 As shown, an annular block 2 is arranged at both ends of the flow meter body 1 through hinge screws 3;

[0035] The annular clamping block 2 includes a first semicircular ring 21 and a second semicircular ring 22, wherein the first semicircular ring 21 and the second semicircular ring 22 form a complete annular block, wherein the inner diameter of the annular block is smaller than the inner diameter of the side of the force-bearing disk 12 away from the main pipe 11, and both sides of the first semicircular ring 21 and the second semicircular ring 22 are provided with hinge ears 23, and the surface of the hinge ears 23 is provided with hinge holes 24;

[0036] Based on the above, the annular clamping block 2 is connected to the force plate 12 through the hinge screw 3. At this time, the annular clamping block 2 is tightly fitted with the end of the flange away from the main pipe 11 to achieve the connection and fixation between the gas pipeline and the flow meter body 1.

[0037] like Figure 1 , Figure 2 , Figure 5 as well as Figure 6 As shown, the hinge screw 3 includes a hexagonal block 31, and a cylindrical block 32 and a threaded column 33 are sequentially arranged at one end of the hexagonal block 31 close to the flow meter body 1, and the threaded column 33 is threadedly connected with the threaded hole 16, and the cylindrical block 32 extends to the inside of the hinge hole 24, and the diameter of the hexagonal block 31 is larger than the inner diameter of the hinge hole 24;

[0038] Based on the above, the hinge screw 3 plays the role of fixing the annular block 2. When only one hinge screw 3 limits the first semicircular ring 21 and the second semicircular ring 22, the first semicircular ring 21 and the second semicircular ring 22 are hinged to each other through the hinge screw 3, which is convenient for adjustment and installation. When the second hinge screw 3 is installed and tightened, the annular block 2 fits tightly against the side of the flange away from the main pipe 11.

[0039] In actual use of this embodiment, by sleeve-mounting the force-bearing plate 12 on the flange of the gas pipeline, the positioning column 14 is inserted into the hole on the surface of the flange. At this time, the first semicircular ring 21 and the second semicircular ring 22 can be sleeved on the outside of the gas pipeline, and the annular block 2 and the mounting ear 15 are connected and fixed to each other through the hinge screw 3, so that the flow meter body 1 and the gas pipeline are connected to each other;

[0040] With respect to the connection and fixation between the flanges, the device makes full use of the shape and structure of the flange itself, supports the flange through the force plate 12 and the positioning column 14, disperses the gravity (i.e., vertical force) on the screw, and reduces the vertical force on the hinge screw 3. Under the premise of not affecting the connection effect and stability, at least one hinge screw 3 needs to be completely removed on one side during disassembly. After the other hinge screw 3 is loosened, the flow meter body 1 can be disassembled by rotating the first semicircular ring 21 and the second semicircular ring 22. The situation of removing only one hinge screw 3 is suitable for when the construction environment is large;

[0041] When the construction environment is small, the two hinge screws 3 on one side can be removed. Compared with the traditional method of at least six screws and nuts on one side, the collector is easier to disassemble and install.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
