Utility model content
In order to solve the problems referred to above, this utility model provides a kind of pressure-balancing adjuster and applies its laser to cut
Cut head.
According to an aspect of the present utility model, it is provided that a kind of pressure-balancing adjuster, including regulation valve, spring with
And end cap, one end of spring is against regulation valve, and the other end of spring connects spring base, and spring base is fixing with end cap to be connected, end
It is covered with relief hole.
It provides the benefit that: the pressure-balancing adjuster of this structure is applicable in the middle of fluid passage, can be in order to
Along spring prolonging direction, regulation valve is applied a thrust with the elastic force of spring so that regulation valve is in the original state of cut out,
Now fluid passage and relief hole are not communicated with, along with the pressure in fluid passage constantly raises, when external and internal pressure difference is more than spring
Elastic force time, the pressure in this pressure-balancing adjuster i.e. convection cell passage be balanced regulation, now, regulation valve flowed
The pressure of body inner fluid passage, moves along spring-compressed direction, and the spring leant with regulation valve is compressed, and regulation valve is beaten
Opening, fluid can flow at end cap by the space between regulation valve and fluid passage, arranges finally by the relief hole on end cap
Going out fluid passage, when inside and outside differential pressure reaches setting value, spring extends, and restores to the original state, and now, regulation valve is again by spring edge
The thrust of its prolonging direction, recovers the original state closed, when next time, inside and outside differential pressure was more than the elastic force of spring again, and circulation
Above balance adjustment step, thus reach the purpose of pressure balance regulation.Pressure-balancing adjuster of the present utility model passes through
The interoperation of spring and regulation valve realize fluid passage in pressure balanced purpose, Principles of Regulation are simple, simple in construction, and
Application is extensive, has good serviceability and application prospect.
In some embodiments, relief hole is the funnel shaped of inner wide and outer narrow.
