Description
Technical field
The present invention relates to closed water system technical field, more particularly to a kind of automatic pressure balance device and
Closed water system.
Background technique
In industrial equipment, water system generally requires certain protection to prevent impurity in environment from penetrating into wherein, avoids making
At water line block.Water system pollutes in order to prevent, and enclosed housing has application under a variety of industrial occasions.Enclosed housing master
It is used to store water needed for water system and other liquid, in order to prevent liquid generation peculiar smell in closed case, in cabinet
Liquid is often added with antiseptic and rustproof additive.
There are a pressure reduction problems with external atmosphere pressure in perfusion for closed cabinet, when filling the water toward closed case, first
What is considered is exactly the exhaust pressure relief problem of cabinet, and if box house gas cannot be emptied effectively, cabinet can be because interior
External pressure difference causes dilatancy, is seriously likely to result in cabinet explosion, therefore the gas emptying of box house just seems especially
It is important.
Currently, the main emptying mode of closed water system is to install an exhaust-valve on water route to carry out manual gas row
Sky, but the device, mainly by artificial adjustment, there are many uncertainties, are often unable to judge accurately the gas emptying of water system
Situation, it is possible to the case where causing water system residual air.
Summary of the invention
The purpose of the present invention is to provide a kind of automatic pressure balance devices, are capable of the pressure balance of guard box inside and outside,
Avoid box deformation.
The technical solution of the present invention is as follows: providing a kind of automatic pressure balance device, it is mounted on the highest position of cabinet,
The automatic pressure balance device includes shell and the floating plug moving up and down being set in the housing, and the shell is equipped with and institute
The exhaust outlet stating the air inlet of box house connection and being connected to the cabinet outside, the floating plug are equipped with for being connected to air inlet
The exhaust passage of mouth and exhaust outlet, is moved up and down by the floating plug in shell to open and close exhaust passage.
The automatic pressure balance device further includes flexible connector, and one end of the flexible connector and the floating plug connect
It connects, the other end of the flexible connector is fixed in the exhaust outlet of the shell.
The flexible connector is spring.
The shell has top and bottom end, and the air inlet is arranged in the bottom end of the shell, and the top of the shell is set
The exhaust outlet is set, the floating plug has top and bottom end, and the top of the floating plug is salable end, and the bottom end of the floating plug is
Free end, the exhaust passage penetrate through the salable end and free end.
The end face of the free end of the floating plug is recessed inwardly to form groove.
The end face at salable end of the floating plug and the inner surface of housing tip close exhaust passage when fitting.
The centre at the salable end of the floating plug be equipped with protrusion, the shell be equipped be located at exhaust outlet below and with exhaust
The recess portion of mouth connection, the shape of the protrusion is adapted with the shape of the recess portion, when closing the exhaust passage, the protrusion
It fits with recess portion.
The automatic pressure balance device further includes flexible connector, one end of the flexible connector and the floating plug
Salable end connection, the other end of the flexible connector are fixed in the exhaust outlet of the shell.
