Description

Dredging device for drain pipe of pressure steam pipeline

Technical Field

The utility model relates to a pull throughs for pressure steam conduit drain pipe belongs to pipeline mediation technical field.

Background

Steam is a heat supply energy used in various industries, needs pipeline transportation, and can not avoid discharging condensed water in the pipeline transportation process. The problems are that the drainage is not smooth due to frequent blockage of a condensed water pipeline and a valve, the pressure in a steam pipeline is not good, and the steam pipeline can be dredged only by stopping steam delivery. Thus, a special pull through is lacking.

SUMMERY OF THE UTILITY MODEL

The utility model provides a pull throughs for pressure steam conduit trap solves present condensate pipe and valve and often blocks up the problem that leads to hydrophobic unobstructed, has the pressure not good to handle in the steam conduit.

The utility model relates to a pull throughs for pressure steam conduit drain pipe, including dredging pipe, dredging pipe's bottom is equipped with flange, and dredging pipe's middle part one side is equipped with the blow off pipe, is equipped with the blowoff valve on the blow off pipe, and dredging pipe's top threaded connection has the dredging rod that can follow flange and stretch out.

Preferably, an inlet pipe for compressed air or high-pressure water is fixed on one side of the upper part of the dredging pipe, and a switch valve is arranged on the inlet pipe. If the pipeline valve to be dredged cannot use a dredging rod of the dredging device, such as a stop valve, the switch valve is opened, and compressed air or high-pressure water enters from the inlet pipe to dredge the pressure steam pipeline drainage pipeline.

Preferably, the top outside of dredging pipe is fixed with mounting flange, is fixed with the blanking cover on the mounting flange, and dredging rod screw thread is installed on the blanking cover. The installation is convenient.

Preferably, the bottom of the dredging rod is provided with a conical tip, and the blocking cover is fixed on the mounting flange through a bolt. The connection is convenient, and dirt is poked conveniently.

Preferably, a rotating hand wheel is fixed at the top of the dredging rod, and a fixing flange is fixed at the outer end of the sewage discharge pipe.

The utility model discloses, following beneficial effect has:

the steam pipeline drain pipe with pressure can be dredged, and the influence of energy waste caused by steam stop on industrial production is avoided. The flange connection is convenient to install and safe and firm. The use is simple and easy to operate, and the staff can twist the valve to operate. The staff can be operated independently with little training.

Detailed Description

The present invention will be further described with reference to the following examples.

As shown in fig. 1, the utility model discloses a pull throughs for pressure steam conduit drain pipe, including dredging pipe 9, dredging pipe 9's bottom is equipped with flange 5, and dredging pipe 9's middle part one side is equipped with blow off pipe 7, is equipped with blowoff valve 6 on blow off pipe 7, and dredging pipe 9's top threaded connection has the mediation pole 4 that can follow flange 5 and stretch out.

An inlet pipe 3 for compressed air or high-pressure water is fixed on one side of the upper part of the dredging pipe 9, and a switch valve 2 is arranged on the inlet pipe 3.

A mounting flange 11 is fixed on the outer side of the top of the dredging pipe 9, a blocking cover 10 is fixed on the mounting flange 11, and a dredging rod 4 is installed on the blocking cover 10 in a threaded mode.

The bottom of the dredging rod 4 is provided with a conical tip, and the plugging cover 10 is fixed on the mounting flange 11 through a bolt 12.

The top of the dredging rod 4 is fixed with a rotary hand wheel 1, and the outer end of the sewage discharge pipe 7 is fixed with a fixed flange 8. Each pipeline and each valve of the device are made of pressure-resistant and high-temperature-resistant materials, the pressure resistance is not lower than 25Mpa, and the high temperature resistance is not lower than 200 ℃.

The during operation is connected to the raceway valve outer end of treating the mediation with flange 5 during the use, take the labour protection article after the inspection firm in connection, open the valve of treating the mediation raceway, rotatory pull throughs's twist grip 1, pull throughs 4 extension dredges to the pressure blockage raceway, because of treating the dredging raceway for taking the pressure raceway, the filth of jam can discharge the blow off pipe 7 department of pull throughs along with the pressure in the pipeline, rotatory pull throughs blowoff valve 6 again, the filth can be discharged from mounting flange 8. If the pipeline valve to be dredged cannot use a dredging device dredging rod, such as a stop valve, the switch valve 2 is opened, compressed air or high-pressure water enters from the inlet pipe to dredge the pressure steam pipeline drainage pipeline, and then the blow-down valve 6 is opened to discharge dirt.
