Description
Technical field
The present invention relates to a kind of adjusting film more particularly to a kind of pneumatic diaphragm control valves.
Background technique
Closed circulating cooled water regulating valve is related to a kind of cooling sea water regulating valve, is widely used in power station, metallurgy, petrochemical industry etc.
Industrial trade, providing clean, stable cooling water for all kinds of main auxiliary machines makes bearing temperature to control all kinds of main and submachine cooling mediums
Degree control is in a certain range, it is ensured that all kinds of main auxiliary machine safe and reliable operations, such as aerial cooler, hydrogen cooler, oil cooler
And other all kinds of subsidiary engine bearings provide cooling water inflow.Big control valve is opened if temperature height and increases water supply, and temperature is too low, subtracts
Few cooling water inflow guarantees that all kinds of main auxiliary machines operate normally.
Summary of the invention
The present invention provides that a kind of structure is simple, droop loss is small, circulation is big, display is straight in order to solve problem above
It sees, facilitate that adjusting, adjustable extent are big, flow control accuracy is high, anti-seismic performance is good, production cost is low, gas with long service life
Dynamic diaphragm valve.
The technical scheme is that the regulating valve includes valve body, valve seat, spool, guide sleeve, gasket, valve deck, fills out
Material, valve rod, bracket, push rod, spring, diaphragm and membrane cover, the valve body setting exist in regulating valve bottom, the valve seat setting
On valve body, inlet and outlet are symmetrical arranged on the valve body, the spool is arranged in valve seat, and the valve deck connects
Gasket is connect on valve seat and is arranged, the guiding is set in valve seat, and filler, the film are provided in the valve seat
Lid is by bracket setting on valve deck top, and the bracket is hollow out bracket, and the valve rod is connected to membrane cover lower part and passes through
Guiding is set in spool, and the diaphragm is arranged on membrane cover, and the diaphragm is connected with spring, and the push rod is set
It sets between membrane cover and bracket.
Graduation mark is provided on the bracket.
The configuration of the present invention is simple, droop loss are small, circulation is big, intuitive display, facilitate that adjusting, adjustable extent be big, stream
Amount control precision is high, anti-seismic performance is good, production cost is low, long service life.
Detailed description of the invention

Lid 6, filler 7, valve rod 8, bracket 9, push rod 11, spring 12, diaphragm 13 and membrane cover 14, the valve body 1 are arranged at regulating valve bottom
Portion, the valve seat 2 are arranged on valve body 1, and inlet and outlet are symmetrical arranged on the valve body 1, and the spool 3 is set
It sets in valve seat 2, the valve deck 5 is connected on valve seat 2 and is arranged gasket 5, and the guide sleeve 4 is arranged in valve seat 2, institute
Filler 7 is provided in the valve seat 2 stated, the membrane cover 6 is arranged by bracket 9 on 6 top of valve deck, and the bracket 9 is hollow out
Bracket, the valve rod 8, which is connected to 14 lower part of membrane cover and passes through guide sleeve 4, to be arranged in spool 3, and the setting of diaphragm 13 exists
On membrane cover 14, the diaphragm 13 is connected with spring 12, and the push rod 11 is arranged between membrane cover 14 and bracket 9.
Graduation mark 10 is provided on the bracket 9.
Above embodiments are only to illustrate the invention and not limit technical solution described in the invention；Cause
This, is although this specification has been carried out detailed description to the invention referring to above-mentioned each embodiment, this field
It is to be appreciated by one skilled in the art that still can modify to the invention or equivalent replacement；And all do not depart from this
The technical solution and its improvement of the spirit and scope of innovation and creation, should all cover the scope of the claims in the invention
In.
