Abstract
Disclosed is a rubber protector for hot water heating direct-buried heat supply pipeline valve. The rubber protector is composed of a rubber extension cavity and a steel flange; wherein one end of the steel flange is connected with a valve flange and the other end is connected with a pipeline flange. When the pipeline is changed under the action of the heat stress, the rubber extension cavity of the protector plays a flexible connection role and can eliminate radial displacement stress and axial displacement stress of the pipeline, therefore the purpose of protecting the valve body can be achieved.
Description
Affiliated technical field
The utility model relates to a kind of hot water heating heating system direct-burried heating network valve protective gear, and especially repairing brings convenience to valve when preventing the valve fracture.
Background technique
At present; the valve protection of hot water heating direct-burried heating network; the general compensator that adopts the heat distribution pipeline special use; the compensator of the type is made up of metal telescopic cavity and flange; exist and to eliminate pipeline radial displacement stress and the excessive shortcoming of nose balance resistance; can not guarantee the safety of valve, because of telescopic cavity is a Structural Hardware, the nose balance resistance makes troubles for greatly protected valve maintenance.
Summary of the invention
In order to overcome existing compensator; can not eliminate radial displacement stress and the excessive deficiency of nose balance resistance; the utility model provides a kind of rubber valve protector; this protector not only can be eliminated the thermal stress of pipeline; and can play radial displacement stress that overcomes pipeline and the effect that reduces the nose balance resistance, valve is effectively protected.
The technological scheme that its technical problem that solves the utility model adopts is: the end at pipeline and valve joint is installed the rubber valve protector.The rubber valve protector is made up of rubber telescopic cavity and steel flanges, and steel flanges one end is connected with valve flanges, and the other end is connected with flange on the pipeline.When changing under the effect of pipeline in thermal stress, the rubber telescopic cavity of protector works the effect of flexibly connecting, and can eliminate pipeline radial displacement stress and axial stress, reaches the purpose of protection valve.
The beneficial effects of the utility model are, valve fracture in preventing heating network, and when improving the valve working reliability, maintenance brings convenience to valve.
