Abstract
Aiming at the problem that a gas or fluid passage cleaning hole of a water electrolytic bath end pole plate is easy to leak when being sealed, the utility model provides a gas or fluid passage cleaning hole sealing device for a water electrolytic bath end pole plate, which is safe, reliable, leak-proof, simple and convenient in operation, labor-saving and maintenance-free. The device adopts a plug screw assembly for automatic positioning and plugging, namely a steel ball is embedded into the top center of a plug screw to form the assembly; a dedicated gland is arranged between the plug screw and a sealing gasket; an annular sealing line is arranged on each of the sealing surface of the gland and the sealing surface of a threaded hole of the end pole plate. When the plug screw is screwed, the steel ball at the top presses the dedicated gland, the friction is extremely small, and the force bearing point is in the center of the gland, so that the circumference of the sealing gasket is stressed uniformly; the gland presses the sealing gasket, and the sealing gasket is deformed and then fully filled in the sealing surfaces and circumferential gaps, so that a sealing effect is achieved. Under the condition that the working pressure of an electrolytic bath is 1.6<-10>MPa and the temperature difference between a working temperature (85-90 DEG C) and a shutdown temperature (10-20 DEG C) is nearly 70 DEG C, no leakage is realized.
Description
Technical field
The invention belongs to water electrolysis hydrogen producing, oxygen field, be specifically related to a kind of gas, fluid passage wash-out hole tightness system of water electrolyzer end pole plate.
Background technology
At present the multiple adjacent wash-out hole of domestic water electrolyzer end pole plate because of pitch-row little; the general direct precession crush seal of plug screw of many employings; its main drawback is easily to reveal hydrogen, carrier of oxygen and caustic alkali liquid, has great potential safety hazard, needs to shut down maintenance and cause damage very large after leakage.
Summary of the invention
The invention reside in a kind of safety, reliable, nothing leakage are provided, easy and simple to handle laborsaving, the gas of non-maintaining water electrolyzer end pole plate, fluid passage wash-out hole tightness system.
This device adopts the automatic positioning plugging of plug screw assembly, inlayed a steel ball construction components in the center, top of plug screw, between plug screw and gasket seal, installed a special gland additional, the trim of the trim of special gland and end pole plate threaded hole all has ring seal line.In the time screwing plug screw, the steel ball on top is exerted pressure to special gland, frictional force is minimum, stress point is at gland center, make gasket seal periphery stressed evenly, gland is pushed down gasket seal and is made it to be full of trim and gap around after distortion, and gasket seal is squeezed can be by the direct spinning of plug screw time brokenly, reaches sealing effectiveness.At electric tank working pressure 1.6-10Mpa, when working temperature (85-90 DEG C) and shutdown, under approximately 70 DEG C of conditions of temperature head of temperature (10-20 DEG C), realize without leakage, safe, reliable, non-maintaining.
Brief description of the drawings
Fig. 1 is application technical solution of the present invention decomposing schematic representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further:
In conjunction with Fig. 1, the present embodiment is by plug screw 1, steel ball 2, and special gland 3, gasket seal 4, end pole plate threaded hole 5 forms.
Wherein plug screw 1 and steel ball 2 are assemblies, and steel ball 2 is embedded in the center, top of plug screw 1.When installation, first gasket seal 4 is put into end pole plate threaded hole 5 bottoms, then put into special gland 3, screw in plug screw 1 and screw, make gasket seal 4 compress distortion, plugging gap reaches complete sealing effectiveness.
Claims (1)
