Description
Technical field
The invention is related to a kind of freezing prevention tubing water trap and its application method.
Background technology
In modern industry, neither one industrial department be it is dry, also without one industry get along well water directly or
Connect and be related, more industrial utilization water come cooling device or product cooling, and each factory is tieed up using the various effects of water
The normal production of shield, antifreeze waterpipe is also a content very intractable in routine work.
In order to make in pipeline immobilising water not freeze freezing pipeline in severe cold season, two kinds of solution party are typically taken
Method：
One kind is to increase insulation material in pipeline external, and water temperature in pipeline can be made to keep above freezing in the short time, prevented
Volume produces expansion tear bad tube wall after water freezing, undesirable the effect of this method if water does not flow for a long time in pipeline；
Another method is the low spot in pipeline tendency, i.e., the position welding wire head installation row of water can be stockpiled after cutting off the water
Water valve, pipeline can be emptied, laid due to pipeline is influenceed by physical features factor and other constructions, and ups and downs, this just needs
The welded and installed draining valve at the pipeline of all remaining water, quantity is various, and some is dead between pipeline and valve
Pool, it is easily caused icing failure.
Water pipeline is because aerial or buried-pipe laying, and outside have heat-insulation layer, so daily point inspection can only be by estimating and estimating
Meter, accuracy is extremely low, only relies on scheduled overhaul to complete conventional maintenance be extremely difficult, leakage occurs unavoidably, and other
Reason needs to cut off supply channel, the water in pipeline is lost pressure in not flow regime.
Only needing disengagement failure point upland water can in 0 DEG C of weather temperature ＞, during handling failure, easily processing is asked
Topic, but also need to empty residual ponding in all pipelines of cutting off the water in time after severe cold season, closing upper water, now uniquely rely on
Manual operation completes pipe drainage task, not only wastes time and energy, and the aerial laying of many pipelines, higher apart from ground, manually
Job safety risk is larger, so the unartificial draining of pipeline progress to maintenance of cutting off the water is necessary.
The content of the invention
To solve the above problems, the invention provides a kind of freezing prevention tubing water trap and its application method, pass through setting
Bleed valve, discharge tube inner product water problems when solving the stoppage in transit maintenance of severe cold weather lower water-supply-pipe road, meanwhile, prevent freezing pipe
Increase supplementary maintenance expense behind road, reduce the labor intensity and operating risk of personnel, saved the repair time.
To reach above-mentioned purpose, the invention solves by the following technical programs：
A kind of freezing prevention tubing water trap, it is characterised in that including bleed valve, described bleed valve includes overcoat；In overcoat
Wall top coordinates is combined with pressure adjusting nut provided with piston, lower thread, and pressure adjusting nut is provided with logical for what is emptied
Hole；Spring is provided between pressure adjusting nut and piston；It is provided with and is used for and piston bottom surface above outer casing inner wall, pressure adjustment bolt
Cooperation and spacing inner ring；The top of inner ring, overcoat wall are provided with the connection floss hole communicated with overcoat inner chamber；With floss hole
It is connected with connector；Described freezing prevention tubing water trap also includes venting control valve, one end of venting control valve and pipeline
Connection, the other end connect with above-mentioned connector；After above-mentioned bleed valve upper end connection control valve with pipeline communication.
Preferably, it is described outer to put provided with a fixing bolt.
Preferably, the upper surface of inner ring is provided with the sealing ring with piston bottom surface.
Preferably, the periphery of piston is provided with sealing ring.
Preferably, piston and pressure adjustment block are provided with guide pad corresponding with spring.
Preferably, bleed valve is integral by being threadedly coupled with control valve.
Preferably, bleed valve is connected with venting control valve by union, and union horizontal component is in be horizontally mounted or by draining
Control valve to bleed valve direction is in the tendency gradually reduced, is connected by connector with the discharge connector of bleed valve.
A kind of freezing prevention tubing water discharge method, after above-mentioned connected mode；
Manifold pressure is normal, i.e., pipeline normal use when, water under high pressure in pipeline by control valve, enter excretion
Valve, water under high pressure push down on piston, piston and inner ring seal, and water under high pressure enters excretion after discharge connector, connector
Control valve simultaneously finally flows back to pipeline；
When overpressure is reduced, it is necessary to during draining, the low pressure water in pipeline is through controlling bleed valve, connector, discharge to connect
Mouth is entered in the chamber below the piston position of venting control valve, and is passed through the emptying through hole on pressure adjusting nut and discharged.
The operation principle and beneficial effect of the invention are shown：
The invention device includes note bleed valve, venting control valve, control valve, union, chaining part and connecting pipe.
The critical piece of the invention is bleed valve, and it plays a part of a branch leading, passes through connection under high pressure
Pipe communicates with pipeline, is not used in draining；Under low pressure, water can be discharged by bleed valve.
Described bleed valve includes outer tube, piston, pressure adjusting nut, spring, discharge connector and connector.
Its middle external tube, piston, spring, pressure adjusting nut are used to adjust pressure, meet piston can be promoted to enter under high pressure
Row moves, and is not enough to promote piston movement under low pressure.
Whether piston, which is promoted, forms two kinds of mode of communicating：
Mode one：It is exactly under high pressure, promotes piston, piston is in below discharge connector, will be controlled by discharging connector
Valve processed is turned on venting control valve, and water under high pressure is back in pipeline；
Mode two：It is exactly under low pressure, is not enough to promote piston, piston is in more than discharge connector, connected by discharging
Mouthful, by the channel conductive on venting control valve, bleed valve, pressure adjusting nut, so as to realize the discharge of low pressure water.
Bleed valve is integral by being threadedly coupled with control valve, and the connecting pipe by being added on pipeline couples with pipeline.
The horizontal component of union is in be horizontally mounted or by venting control valve to bleed valve direction in the tendency gradually reduced, passes through connector
It is connected with the discharge connector of bleed valve.
When the fluid pressure in pipeline is reduced to setting discharge value, the water in pipeline flows through convergence piece, excretion control
Valve, union and bleed valve discharge.When convergence piece in the device is needed installed in the low spot, i.e. service conduits draining of pipeline tendency
Low dot location.
To sum up, it is the advantages of this equipment：
1st, the labor intensity and operating risk of operating personnel can be reduced.
2nd, there is no slough in the present apparatus, will not freeze to fail due to severe cold season.
3rd, the spring adjustment that the present apparatus is taken, can arbitrarily adjust discharge pressure as needed.
