Description
Technical Field
The utility model relates to a gas pipeline field, in particular to prevent that rainwater from getting into rain-proof cap of gas pipeline.
Background
In order to prevent the gas equipment from being out of order and generating pressure higher than the design pressure or needing to replace the gas pipeline, a gas diffusion pipe is required to be arranged during the design. The gas diffuses the pipe and opens to the outside, often has the rainwater to get into the gas pipeline, leads to pipeline and valve to corrode, or directly gets into precision facilities such as voltage regulator or table utensil, brings the influence for the facility.
To prevent rainwater from entering, two methods are generally adopted: (1) the diffusing pipe is not upward, and the elbow is used for facing horizontally or downward, but the appearance is not attractive; rainwater cannot be thoroughly prevented from entering; resistance is also added to the diffusion; (2) a rain cover is arranged on the diffusing pipe, and diffusing holes are arranged on two sides of the rain cover. The rain cover is beautiful; but has limited rain protection performance; and the area of the diffusing hole can not meet the designed diffusing amount.
Therefore, it is necessary to provide a new rain cap for preventing rainwater from entering the gas pipeline to solve the above problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a prevent that rainwater from getting into rain-proof cap of gas pipeline can realize the automatic of superpressure natural gas and diffuse, avoids sleet, dust, mosquito and bird and beast's entering, avoids diffusing the pipe and corrodes, guarantees diffusing the unblocked of pipe, and can satisfy the design volume of diffusing.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a prevent rain-proof cap that rainwater got into gas pipeline, its includes fixed pipe, sets up guard plate, a plurality of coupling mechanism of setting between antiskid ribbed tile and fixed pipe of fixed pipe top, coupling mechanism includes connecting rod and support, fixed pipe is articulated with the one end of connecting rod, the other end of connecting rod is articulated with the one end of support, the other end and the guard plate of support are articulated, be equipped with two fixed subassemblies on the fixed pipe.
Specifically, the fixed subassembly includes mounting plate and three fastening bolt, the mounting plate sets up in diffusing intraductally, fastening bolt passes fixed pipe, fixing bolt supports with the mounting plate and leans on.
Specifically, the fastening piece is provided with anti-skid stripes.
Specifically, a limiting groove is formed in the protection plate.
The utility model has the advantages that the rain-proof cap for preventing rainwater from entering the gas pipeline can realize the automatic diffusion of overpressure natural gas; rain, snow, dust, mosquitoes, birds and beasts can be prevented from entering the diffusion pipe, the corrosion of the diffusion pipe is avoided, and the smoothness of the diffusion pipe is ensured; in addition, the protection plate can meet the design dispersion amount and can be prevented from being separated through the support and the connecting rod.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic view of the installation structure of the rain hat for preventing rainwater from entering the gas pipeline;
fig. 2 is a schematic structural view of a protection plate of the rain hat for preventing rainwater from entering the gas pipeline;
fig. 3 is a schematic structural view of a fixing pipe of the rain hat for preventing rainwater from entering the gas pipeline;
in the figure: 1. the device comprises a fixed pipe, 2 connecting rods, 3 supports, 4 protection plates, 5 diffusing pipes, 6 fastening bolts, 7 fastening pieces and 8 limiting grooves.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1, the rain hat for preventing rainwater from entering a gas pipeline comprises a fixed pipe 1, a protection plate 4 arranged above the fixed pipe 1, and a plurality of connecting mechanisms arranged between an anti-skid plate and the fixed pipe 1, wherein each connecting mechanism comprises a connecting rod 2 and a support 3, the fixed pipe 1 is hinged to one end of the connecting rod 2, the other end of the connecting rod 2 is hinged to one end of the support 3, the other end of the support 3 is hinged to the protection plate 4, and two fixed assemblies are arranged on the fixed pipe 1.
As shown in fig. 3, the fixing assembly includes a fastening plate 7 and three fastening bolts 6, the fastening plate 7 is disposed in the diffusing pipe 5, the fastening bolts 6 pass through the fixing pipe 1, and the fixing bolts abut against the fastening plate 7. First, the fastening bolt 6 in the middle of the three fastening bolts 6 is rotated so that the middle of the fastening tab 7 abuts against the diffusing pipe 5, and then the other two fastening bolts 6 are rotated so that both sides of the fastening tab 7 abut against the diffusing pipe 5.
As shown in fig. 2, the fastening plate 7 is provided with anti-slip stripes. The anti-slip stripes can increase the friction between the fastening tabs 7 and the diffusing pipe 5, thereby preventing the fixing pipe 1 from slipping on the diffusing pipe 5.
Specifically, a limiting groove 8 is arranged in the protection plate 4. Spacing groove 8 is the same with the size of diffusing pipe 5, and when no air pressure or atmospheric pressure were lower in diffusing pipe 5, protection plate 4 tightly covered diffusing pipe 5 through spacing groove 8, prevented that rainwater, dust, mosquito from getting into diffusing pipe 5.
This prevent that rainwater from getting into rain-proof cap's of gas pipeline theory of operation: when the diffusing pipe 5 does not perform diffusing work, the protection plate 4 is firmly clamped at the top end of the diffusing pipe 5 through the limiting groove 8 under the action of self gravity to completely cover the pipe orifice of the diffusing pipe 5 so as to prevent rainwater, dust and mosquitoes from entering the diffusing pipe 5; when needs are diffused, the atmospheric pressure in the diffusion pipe 5 rises rapidly, and the protection plate 4 floats upwards through the cooperation of connecting rod 2 and support 3 under the pressure effect of diffusion gas and jacks up the protection plate 4 and discharges gas out, and when atmospheric pressure reduced, the protection plate 4 moves downwards under the action of self gravity, so that the protection plate 4 covers the diffusion pipe 5.
Compared with the prior art, the rain-proof cap for preventing rainwater from entering the gas pipeline can realize automatic diffusion of overpressure natural gas; rain, snow, dust, mosquitoes, birds and beasts can be prevented from entering the diffusion pipe 5, the diffusion pipe 5 is prevented from being corroded, and smoothness of the diffusion pipe 5 is guaranteed; in addition, the protection plate 4 can meet the design dispersion amount and prevent the protection plate 4 from being separated through the support 3 and the connecting rod 2.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
