In this way, the utility model discloses can carry out current -limiting restraint to ground sewer pipe, avoid rivers too rapid lead to the fact certain pressure and with this body pressure of pipeline broken, the inside ladder limit stream block of pipeline body can lighten pipeline body burden with the rivers current -limiting when rivers are too big, prolong long pipeline body life.
Description
Technical field
This utility model relates to underground water pipeline field, particularly relates to a kind of underground water pipeline with ladder current limliting block。
Background technology
Underground piping is to be laid in underground for carrying the pipeline of liquid, gas or bulk solids。Act on the load on underground piping, mainly there are vertical and horizontal pressure force and geological process etc. that pressure medium in self weight of pipeline, pipe, vertical and horizontal earth pressure, groundwater pressure, ground mobile load produce, wherein except pressure medium in pipe deadweight and pipe, it is related with the pipeline soil body all directly or indirectly。Pipeline is not only further applied load by the soil body, and the deformation of pipeline is risen effect of contraction。The rigidity of the rigid pipes such as armored concrete, cast iron, asbestos-cement pipe is big, vertical and level is all only small to deformation, and the native elastic resistance thus caused is only small。Therefore, act on the horizontal earth pressure on pipeline generally by earth pressure computation。To flexible pipes such as steel pipe, corrugated steel tube, glass tubings, under vertical earth pressure effect, its deformation is up to the 2～5% of pipe diameter, and corresponding level is subject to the constraint of the elastic resistance of soil to deformation, so that the bearing capacity of vertical earth pressure is improved by pipeline accordingly。And underground water pipeline is also from internal pressure, when current are excessive, timely current limliting is by flow cavitation result, build-up of pressure crosses the situation of big pipe explosion, and often all very big at the current of underground water pipeline internal flow during some area rainfall, flood discharges, it is easy to occur that burst conditions causes some problems。
Utility model content
This utility model is mainly solving the technical problems that provide a kind of underground water pipeline with ladder current limliting block, it is possible to underground water pipeline is carried out current limliting constraint, it is to avoid current are too rapid causes certain pressure to be crushed by pipeline body。
For solving above-mentioned technical problem, the technical scheme that this utility model adopts is: provide a kind of underground water pipeline with ladder current limliting block, including pipeline body, described pipeline body is layed in underground, described pipeline body two ends connect, a ladder current limliting block it is provided with inside described pipeline body, described ladder current limliting block upper end is fixed on the tube wall of described pipeline body upper end, described ladder current limliting block front end is provided with multilamellar and heads on current limliting step, described head-on current limliting step interior receipts backward extends, and described head-on step angle, current limliting step front end is arc angling。
In one preferred embodiment of this utility model, described pipeline body one end offers water inlet, and the described pipeline body other end offers outlet, connects between water inlet with outlet。
In one preferred embodiment of this utility model, the multiple described head-on current limliting step uniform height that described ladder current limliting block front end is arranged is arranged。
In one preferred embodiment of this utility model, described ladder current limliting block is a solid slug, and between described ladder current limliting block and described pipeline body, integral type is connected。
The beneficial effects of the utility model are: underground water pipeline can be carried out current limliting constraint by this utility model, avoid that current are too rapid causes certain pressure to be crushed by pipeline body, current current limliting can be alleviated pipeline body burden by the ladder current limliting block within pipeline body when current are excessive, extends pipeline body service life。
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, below the accompanying drawing used required during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of this utility model underground water pipeline one preferred embodiment with ladder current limliting block；
In accompanying drawing, the labelling of each parts is as follows: 1, pipeline body；2, ladder current limliting block；3, head on current limliting step。
Detailed description of the invention
Technical scheme in this utility model embodiment will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present utility model, rather than whole embodiments。Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection。
Referring to Fig. 1, this utility model embodiment includes:
A kind of underground water pipeline with ladder current limliting block, including pipeline body 1, described pipeline body 1 is layed in underground, described pipeline body 1 two ends connect, described pipeline body 1 is internal is provided with a ladder current limliting block 2, and described ladder current limliting block 2 upper end is fixed on the tube wall of described pipeline body 1 upper end, and described ladder current limliting block 2 front end is provided with multilamellar and heads on current limliting step 3, described head-on current limliting step 3 interior receipts backward extends, and described head-on step angle, current limliting step 3 front end is arc angling。
It addition, described pipeline body 1 one end offers water inlet, described pipeline body 1 other end offers outlet, connects between water inlet with outlet。
It addition, multiple described head-on current limliting step 3 uniform height that described ladder current limliting block 2 front end is arranged is arranged。
It addition, described ladder current limliting block 2 is a solid slug, between described ladder current limliting block 2 and described pipeline body 1, integral type is connected。
Operation principle of the present utility model for being layed in underground by pipeline body 1, pipeline body 1 two ends connect, pipeline body 1 one end offers water inlet, pipeline body 1 other end offers outlet, connect between water inlet with outlet, pipeline body 1 is internal is provided with a ladder current limliting block 2, ladder current limliting block 2 is a solid slug, between ladder current limliting block 2 and pipeline body 1, integral type is connected, ladder current limliting block 2 upper end is fixed on the tube wall of pipeline body 1 upper end, ladder current limliting block 2 front end is provided with multilamellar and heads on current limliting step 3, head-on current limliting step 3 interior receipts backward extends, head-on step angle, current limliting step 3 front end is arc angling, multiple head-on current limliting step 3 uniform height that ladder current limliting block 2 front end is arranged are arranged, when pipeline body 1 internal drainage amount is excessive, the current sprung up up can be compressed by ladder current limliting block 2, the water flow flowing through pipeline body 1 rear end is reduced, the ladder current limliting block 2 of notch cuttype can slowly reduce water flow, rather than the situation that quickly controls to result in blockage by water flow, and then play metering function, alleviate the pressure of pipeline body 1, increase the service life。
