The underground pipeline pressure test detection apparatus is advantaged by simple structure, ease of manufacture, low cost, strong practicality, safety and reliability, repeatable utilization, and capability of lowering construction cost.
Description
Technical field
The utility model relates to a kind of pipeline pressure testing device, in particular, relates to a kind of groundwater supply steam line pressure testing/detecting device.
Background technology
Underground pipeline needs pressure testing after installing, rear without leaking to guarantee that pipeline is used.Large-scale pipeline, in long-distance pipe work progress, in order to shorten construction period, adopts section construction and pipe section pressure test, yet in existing pipe section pressure test mode, need to weld respectively blind plate at each section, and install the auxiliary pressure test devices such as water injection pipe, tensimeter, ajutage additional, carry out pressure testing; Owing to adopting pipe section pressure test mode, the materials such as blind plate and pressure testing water can only be used once, and all will again install and dismantle various servicing units additional at every turn, and cost is high, and workload is large.
Utility model content
The utility model is for the deficiency of existing product, and a kind of underground pipeline pressure testing/detecting device simple in structure, practical, safe and reliable, reusable is provided.
Underground pipeline pressure testing/detecting device of the present utility model, described device comprises pressure testing pipeline, back support seat, described pressure testing pipe ends is provided with pressure testing pipe and connects, the pressure testing pipe in described left side taps into water pipe in succession, in the middle of described water inlet pipe, be provided with pitcher pump and pitcher pump water inlet, water inlet pipe upper end is provided with forefront pressure table, and the pressure testing pipe portion of connecting on described right side is provided with gas outlet, and described gas outlet end is provided with tail end tensimeter.Described water inlet pipe front end connects flow spill valve.Described pressure testing pipe connect and back support seat between be provided with freeing port.
The beneficial effects of the utility model are: (1) is simple in structure, are easy to manufacture, and cost is low; (2) practical, safe and reliable; (3) can reuse, can reduce construction cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: flow spill valve 1, forefront pressure table 2, pressure testing pipe connect 3, pitcher pump 4, pitcher pump water inlet 5, water inlet pipe 6, pressure testing pipeline 7, tail end tensimeter 8, gas outlet 9, freeing port 10, back support seat 11.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
In the drawings, underground pipeline pressure testing/detecting device of the present utility model mainly by flow spill valve 1, forefront pressure table 2, pressure testing pipe connect 3, pitcher pump 4, pitcher pump water inlet 5, water inlet pipe 6, pressure testing pipeline 7, tail end tensimeter 8, gas outlet 9, freeing port 10, back support seat 11 form.
Described pressure testing pipeline 7 two ends are provided with pressure testing pipe and connect 3, the pressure testing pipe in described left side connects 3 connection water inlet pipes 6, in the middle of described water inlet pipe 6, be provided with pitcher pump 4 and pitcher pump water inlet 5, water inlet pipe 6 upper ends are provided with forefront pressure table 2, the pressure testing pipe on described right side connects 3 tops gas outlet 9 is installed, and described gas outlet 9 ends are provided with tail end tensimeter 8.Described water inlet pipe 6 front ends connect flow spill valve 1.Described pressure testing pipe connect 3 and back support seat 11 between be provided with freeing port 10; Back support seat 11 effect is that pressure testing pipe in supporting pipeline two ends connects 3 and prevents from coming off.
During pressure testing, by water inlet pipe 6, in pressure testing pipeline 7, fill with pressure testing water, and pitcher pump 4 is filled with and added hydraulic water; When water is filled with to a certain extent, can from the spout hole of flow spill valve 1, flow out, at this time close inlet valve and flow spill valve 1, open gas outlet 9 exhausr port valves, until by the air of pipe interior from exhausr port all discharge, pressure testing water flows out, and now closes exhausr port valve, the exhausr port of opening pressure table lower end, until air and water flow out, start note and press, observe tensimeter and can detect.
