The cost of raw sound, loudspeaker or whistle is relatively low, and simple to install is convenient, and can sounding realize warning function, it should be pointed out that
It is that also can be achieved on warning function using some sensors, simply cost is higher for relative loudspeaker or whistle and connects
Inconvenience.
More stably it is arranged in order that obtaining anode zinc bar 8 on valve body 1, feed pathway 5 and liquid outlet channel 6 are provided with peace
Hole 9 is filled, anode zinc bar 8 is installed in mounting hole 9.There is gap in anode zinc bar 8, seawater can lead to when being installed with mounting hole 9
Gap infiltration is crossed so as to corrode the hole wall of mounting hole 9, causes anode zinc bar 8 to loosen, in addition, being finished in replacing or zinc bar
When, seawater can corrode mounting hole 9, and the hole wall of the mounting hole 9 in the present embodiment is provided with corrosion-inhibiting coating 10, so as to avoid mounting hole
9, which are corroded and ensure that anode zinc bar 8 is firm, is arranged on mounting hole 9, Stability Analysis of Structures.
In addition, feed pathway 5 and liquid outlet channel 6 are welded with fixed seat 11 in each top side of mounting hole 9, anode zinc bar 8 passes through
Mounting hole 9 and fixed seat 11 is bolted in, fixed seat 11 causes whole device to remove and install conveniently, also avoids in installation anode zinc bar
Valve body 1 is damaged when 8.It is pointed out that except using the fixed anode zinc bar 8 of fixed seat 11, can also be in the outside of valve body 1
Set nut to be connected with one end of anode zinc bar 8, thus anode zinc bar 8 is fixed, fixed form is not limited solely to this
Embodiment；Anode zinc bar 8 can also be arranged on valve body 1 by a variety of connected modes, such as riveting, welding etc., can not office
The mounting means being limited in the present embodiment.
Anode zinc bar 8 in the present embodiment is circular zinc bar, a diameter of 3-5cm of circular zinc bar, the length of circular zinc bar
For 5-12cm, the easier for installation of anode zinc bar 8 is caused using circular zinc bar, and it is easily manufactured, and select above-mentioned size to advise
The anode zinc bar 8 of lattice is while can stablize anti-corrosion so that the replacement cycle of anode zinc bar 8 is suitable.
Preferably, the material of valve body 1, check valve piece 2, bonnet 3 and guide rod 4 is spheroidal graphite cast-iron, carbon steel, chrome-molybdenum steel or not
Become rusty steel in any one, can be as the moon of galvanic cell using the valve body 1 of above-mentioned material, check valve piece 2, bonnet 3 and guide rod 4
Pole is protected, and structural strength is high.
To sum up, feed pathway 5 and liquid outlet channel 6 are provided with, is entered using the anti-corrosion stop valve of the embodiment of the present invention, valve body 1
The connectivity part of liquid passage 5 and liquid outlet channel 6 is back valve port 7, and check valve piece 2 is buckled in back valve port 7, and check valve piece 2 is led to along liquid is gone out
Road 6 is flowed to feed pathway 5 and fastened, and thus the current of liquid outlet channel 6 can not push up open check valve piece 2, avoid the water of liquid outlet channel 6
Stream is back in feed pathway 5 by returning valve port 7, ensures that the anti-corrosion stop valve is stable；The inwall of feed pathway 5 and go out liquid
The inwall of passage 6 is respectively removably provided with least one anode zinc bar 8, because whole valve body 1 is turned on by seawater, is formed former
Battery structure, and anode zinc bar 8 is stronger relative to the other structures movable metallic of stop valve, so that anode zinc bar 8 is made
For the sacrificed anticathode of galvanic cell, and the miscellaneous part of anti-corrosion stop valve is protected as the negative electrode of galvanic cell, relative to tradition
Anticorrosive coat protection, the antiseptic property of the anti-corrosion stop valve is good, and anode zinc bar 8 is detachable and changes, and ensures that the anti-corrosion is cut
The only stable anti-corrosion of valve；When anode zinc bar 8 is consumed to the accommodating chamber position of upper end, seawater occurs instead with the reactant 12 in accommodating chamber
Gas and should be produced, gas is by air-flow acoustical generator 13 and sends sound, thus reminds operating personnel to change anode zinc bar in time
8, the stop valve is avoided by seawater corrosion.
