The present invention will be described in detail below with reference to the accompanying drawings and embodiments creates.
A kind of moisture-proof electromagnetic flowmeter, as shown in Figure 1 to Figure 3, including measurement pipe 14 and 14 both ends of measurement pipe correspondence are set
The ring flange 1 set；It is equipped with lining 2 in measurement pipe 14, shell 3 is installed outside measurement pipe；The shell 3 includes 4 He of upper housing
Lower case 5, upper housing 4 and lower case 5 are connected by bolt 6；The upper housing 4 is equipped with pacifies for installing flow converter 9
Seat 7 is filled, mounting base 7 is equipped with the through-hole 8 passed through for conducting wire；The shell 3 is equipped with moisture-proof component, and shell two sides, which are equipped with, to be used
Annular partition 10 there are two being set in the position for corresponding to mounting portion 301 on the mounting portion 301 for installing moisture-proof component, measurement pipe, partition
10 are equipped with several ventholes 11, are equipped with electromagnetic coil 15 and electrode 16 in the measurement pipe between two annular partitions 10,
It is connect by conducting wire with electrode using existing flow converter 9, the mounting means of electromagnetic coil and electrode is existing
Technology is not repeating herein.
The moisture-proof component includes the plastic spacer 12 and plastic spacer being arranged on shell 3 towards 14 side of measurement pipe
The moisture barrier bag 13 being arranged on 12；Barrier material is filled in the moisture barrier bag 12.It can be with by the venthole that is arranged on partition 10
Adsorb the moisture near electromagnetic coil sufficiently by the moisture barrier bag that partition two sides are arranged, partition is guaranteeing that coil electromagnetism coil is moisture-proof
While effect, it can be also used for fixed moisture barrier bag and keep apart moisture barrier bag and electromagnetic coil, moisture barrier bag is avoided to squeeze electromagnetism
Coil guarantees that electromagnetic coil can work normally.
On shell 3, shell 3 is equipped with the T-slot for plastic spacer to be arranged for the setting that the plastic spacer 12 slides,
T-slot is arranged on the shell in a ring and is equipped with the opening for installing plastic spacer in upper housing and lower case junction,
Since plastic spacer is than relatively thin, so plastic spacer can be easily bent, this is more advantageous to the T-slot of plastic spacer and annular
Cooperation.Because shell is divided into upper housing and lower case, and upper housing and lower case are bolted, so shell is dismantled
After can very easily replace moisture-proof component, since moisture barrier bag is arranged on plastic spacer, and plastic spacer is slidably arranged in type
In slot, so when needing replacing moisture barrier bag, shell need to only be dismantled, then pull plastic spacer, by plastics disc from T-slot
One end pulls out, and after old moisture barrier bag takes out, need to only can be completed by the plastic spacer push-in T-slot for having new moisture barrier bag
Replacement, operates very easy, substantially increases the replacement efficiency of moisture-proof component, avoids influencing the normal work of electromagnetic flowmeter
Make, while T-slot can also very easily fix plastic spacer, so that fixed moisture barrier bag, avoids moisture barrier bag mobile, it is logical in this way
Cross the common fixation of T-slot and partition, so that it may avoid moisture barrier bag to influence electromagnetic flowmeter very well and work normally, to make moisture-proof
Bag can be stable effect, improve the humidity resistance of electromagnetic flowmeter.
The barrier material uses silica-gel desiccant or calcium oxide desiccant, can also use other existing desiccant.
It is arranged at intervals with multiple moisture barrier bags on the plastic spacer, multiple moisture barrier bags are arranged by interval, can be further increased moisture-proof
The contact area of bag and air, to greatly improve the dampproof effect of moisture barrier bag, while by the way that moisture barrier bag interval to be arranged, also making
Obtaining plastic spacer can preferably be installed in T-slot, and plastic spacer is avoided to damage moisture barrier bag when extending.
The shell 3 be equipped with the matched locating slot of partition 10, not only shell can be made more stable by locating slot
It is mounted in measurement pipe, and can prevent shell from moving in measurement pipe, to avoid moisture barrier bag from rupturing, while outer in installation
It can also be matched by locating slot and partition when shell, the installation site of shell quickly be positioned, to greatly accelerate the peace of shell
Speed is filled, assembling speed when replacement moisture barrier bag is improved.
The invention substantially increases the dampproof effect of electromagnetic flowmeter, increases by the way that moisture-proof component is arranged on the shell
The service life of electromagnetic coil and electrode is added, to guarantee the work that electromagnetic flowmeter can be stable for a long time；It is needing more
When changing moisture barrier bag, plastic spacer only need to be pulled, plastics disc is pulled out from T-slot one end, after old moisture barrier bag takes out, only
Replacement need to be being can be completed in the plastic spacer push-in T-slot for having new moisture barrier bag, operate very easy, substantially increase
The replacement efficiency of moisture-proof component, avoiding, which influences electromagnetic flowmeter, works normally, while T-slot can also very easily fix modeling
Backing strap piece passes through the common fixation of T-slot and partition, so that it may moisture barrier bag be avoided to influence to avoid moisture barrier bag mobile in this way
Electromagnetic flowmeter works normally, so that the effect for keeping moisture barrier bag stable, improves the humidity resistance of electromagnetic flowmeter.
The foregoing is merely the preferred embodiments of the invention, are not intended to limit the invention creation, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on should be included in the invention
Protection scope within.
