Description
Technical field
The utility model is a kind of constant flow valve for guarding against theft, belongs to valve field.
Background technology
Currently, hot water is all lost in large quantities daily in operation by heat supply company, not only waste water resource, also loses in large quantities
Thermal energy, according to investigations the expense of each Heating Season dehydration account for the 3% of total energy consumption.Same problem appears in pipeline road, natural gas
In transfer pipeline and tap water supply system.
In existing valve for guarding against theft technology, flow is caused to increase stolen, robber's gas, stolen water and user's family accident dehydration occurs
When big, simply valve can only be closed and can not be reopened automatically, need manual intervention that could restore again, it is time-consuming to take
Power is badly in need of a kind of valve for guarding against theft, can realize the closing and unlatching of valve automatically according to traffic needs.
Utility model content
The utility model is directed in existing valve for guarding against theft technology, and stolen is occurring, is stealing gas, stolen water and user's family accident
When dehydration causes flow to increase, simply valve can only be closed and can not be reopened automatically, need artificial participation could again
Secondary recovery, waste of manpower, and the technical issues of inefficiency provide and a kind of are needed to set metered flow according to actual flow
Afterwards, when generation stolen, robber's gas, stolen water and user's family accident dehydration cause flow to increase, valve is can be automatically closed, is waited for
The phenomenon is i.e. automatic after disappearing to restore normal use, time saving and energy saving constant flow valve for guarding against theft.
For this purpose, the technical solution of the utility model is, a kind of constant flow valve for guarding against theft is equipped with valve body, valve body be equipped with into
Mouth end and outlet end, valve body is interior to be equipped with valve seat, and valve seat is equipped with spring, and valve seat right side is equipped with valve plate, valve plate other end
Equipped with thrust washer, valve body is equipped with sealing hole, and valve seat is equipped with sealing surface, and valve seat is equipped with flowing hole, and valve plate is equipped with
Constant current metering-orifice, valve plate are equipped with centre bore, and valve body is equipped with return port, valve body, valve seat, spring, valve plate and thrust washer
Material is resistant material.
Preferably, valve plate is equipped with constant current metering-orifice.
Preferably, spring can be replaced with bellows.
Preferably, the sealing surface of valve seat is hemispherical.
Preferably, the sealing surface of valve seat is cone.
Preferably, for valve body using casting copper or stainless steel, spring uses stainless steel, valve seat that plastics, valve plate is used to use
Potsherd.
Preferably, valve seat is equipped with bolt.
The utility model has the beneficial effects that due to being equipped with valve body, valve seat is equipped in valve body, valve seat is equipped with spring, valve
Seat right side is equipped with valve plate, and valve plate other end is equipped with thrust washer, and valve body is equipped with sealing hole, and valve seat is equipped with sealing
Face, valve seat are equipped with flowing hole, and valve plate is equipped with constant current metering-orifice, and valve plate is equipped with centre bore, and valve body, spring, is matched at valve seat
Flow table and thrust washer material are resistant material, are caused stolen, robber's gas, stolen water and user's family accident dehydration occurs
When flow increases, because the flow by valve increases, valve inlet end and outlet port differential pressure become larger, and spring is compressed, valve seat
Sealing surface and valve body sealing hole coordinate, realize automatic-closing valve, due to valve body be equipped with return port, valve close shape
Under state, Oil, Water, Gas can slowly be flowed through small holes, realize that the pressure balance at valve body import end and outlet end, valve are opened again
It opens, without monitoring, does not also need manual operation, it is time saving and energy saving.

Specific implementation mode
The utility model is described further with reference to embodiment.
A kind of constant flow valve for guarding against theft, is equipped with valve body 1, and valve body 1 is equipped with input end 8 and outlet end 7, is equipped in valve body 1
Valve seat 2, valve seat 2 are equipped with spring 3, and spring 3 can also be replaced with bellows, and valve seat 2 is equipped with flowing hole 12,2 right side of valve seat
It equipped with valve plate 5, is set on valve plate 5 there are four constant current metering-orifice 4, this four 4 sizes of constant current metering-orifice are different, coordinate flowing hole 12
For different flow controls, 5 other end of valve plate is equipped with thrust washer 9, and valve seat 2 is equipped with bolt 6, will by bolt 6
Valve plate 5 and valve seat 2 are fixed, and valve plate is equipped with square central hole 14, with 2 inner hole of valve seat, in valve plate 5 and valve body 1
The smooth clearance fit in hole, valve seat 2 and the smooth clearance fit of 1 endoporus of valve body, valve body 1 are equipped with sealing hole 10, and valve seat 2 is equipped with close
Cover 13, sealing surface 13 can be hemisphericals, can also be cone or planar structure, when oil, water or natural gas are by import
End 8 enters valve body 1, if actual flow is less than setting flow, spring 3 is not compressed, system worked well；If occurring in pipeline
When stolen, stolen water, robber's gas phenomenon, actual flow is caused to be more than setting flow, input end 8 and outlet end 7 generate pressure difference, then spring
3 are compressed, and are eventually led to sealing surface 13 and are coordinated with sealing hole 10, valve is closed, and valve body 1 is equipped with return port 11, works as sealing surface
13 with sealing hole 10 when coordinating, and still can have the oil, water or gas of small flow by return port 11, gradually realize pressure at two ends
Balance, sealing surface 13 are detached from sealing hole 10, restore normal operating conditions.Valve body 1, valve seat 2, spring 3, valve plate 5 and thrust pad
It is resistant material to enclose 9 materials, and for valve body 1 using casting copper or stainless steel, spring 3 uses stainless steel, valve seat 2 to use plastics,
Valve plate 5 uses potsherd, this material configuration that can meet the requirement of oil, water and natural gas to conveying pipe fitting material, can
The operation steady in a long-term of guarantee system.
Only as described above, only specific embodiment of the utility model, when the utility model cannot be limited with this
