Abstract
The utility model discloses a diaphragm jar capsule protection shield, in supplying drainage system, unfamiliar jar has generally all been installed, circle in the flange that the diaphragm jar docked rather than the delivery port flange mutually, welded and bored the sphere board that has 5 water -guiding holes of phi, when water pump in supplying drainage system stops, the capsule of diaphragm jar can be to the out -draw under nitrogen pressure's promotion, nevertheless because the prevention of foraminiferous sphere board, make it unable and continue outside the removal, just so prevented that the capsule in unfamiliar jar from being elongated the attenuation and bursting by the exceedingly, stop to supply the emergence of drainage system accident.
Description
Technical field
The utility model patent relates to a kind of capsule protection device, is specifically related to the capsule guard shield in a kind of diaphragm pot.
Background technology
In the system of fire fighting supply and living water, in order to stable hydraulic pressure, eliminate water hammer, generally diaphragm pot is all installed, diaphragm pot is made up of its tank body and capsule, and the water hammer of effect mainly in order to receive water drainage-supply system to produce of capsule, is filled with between capsule and diaphragm pot housing and is with 2kg/cm
2the nitrogen of pressure.When running at ordinary times; system is because the startup of water pump produces instantaneous high pressure water hammer; instantaneous high pressure water hammer is large for the capsule support in tank body; and its ambient nitrogen is compressed; the water hammer of such water system is by the nitrogen adsorption outside capsule, and the valves and fittings protected in water system can not damage because of high hydraulic pressure.Once termination of pumping, system decompression, the pressure of the nitrogen release storage in diaphragm pot, clamp-ons in water system by the water in capsule, supplements the pressure of water system loss.After termination of pumping, if system hydraulic pressure is very little, the bottom of capsule can be pushed in the pipeline of tank body lower part by nitrogen with pressure, the stressed maximum position, bottom of capsule can be elongated, and becomes very thin, and then cannot bear the pressure of nitrogen and burst, send huge sound, even security incident occurs, capsule explosion metacneme tank cannot continue to play the effect eliminating water hammer in water system, affects production and the life of people.
Summary of the invention
The utility model is an embodiment patent, is to weld one block of spherical plectane with water-guiding hole in the flange inner ring connected with diaphragm pot delivery port flange, and spherical plate projection faces diaphragm pot.
The technical characteristic of the utility model patent is, spherical plate has been bored numerous water-guiding holes, ensure that the water of adjustment hydraulic pressure is with easy access.
Another technical characteristic of the present utility model is, diaphragm pot capsule guard shield is made outwardly spherical plate, effectively prevents diaphragm pot capsule local to be elongated, draws thin, and then prevent the generation of diaphragm pot capsule bursting accident.
A kind of diaphragm pot capsule of the utility model guard shield; its beneficial effect is: ensure that diaphragm pot capsule is while receiving the water hammer produced due to starting mode of pump; again can when water pump stops; ensure that capsule is not pushed by the pressure of nitrogen in the pipeline of diaphragm pot bottom; be elongated thinning, thus prevent the generation of diaphragm pot capsule bursting accident.

Detailed description of the invention
The utility model is the structure of an embodiment, is described in detail below in conjunction with accompanying drawing 1,2,3 pairs of the utility model patents.
A kind of diaphragm pot capsule of the utility model patent guard shield is relevant to the flange (6) that diaphragm pot (1), diaphragm pot delivery port flange (2), diaphragm pot capsule (3), spherical plate (4), water-guiding hole (5) and diaphragm pot delivery port flange connect.A kind of diaphragm pot capsule of the utility model patent guard shield; by the thick spherical plate (4) of the 4mm of hydraulic press punching one-tenth; spherical plate (4) is drilled with the water-guiding hole (5) of numerous φ 5; after diaphragm pot capsule (3) guard shield is made, be welded on the inner ring of the flange (6) that diaphragm pot delivery port flange connects.During starting mode of pump in water system, produce the high pressure of moment, because the material of all accessories is rigidity in water system, thus the deformation produced is minimum, and the material of diaphragm pot capsule (3) is rubber, it has good retractility, the instantaneous pressure that starting mode of pump produces acts on the inner side of diaphragm pot capsule (3) by the water-guiding hole (5) in spherical plate (4), diaphragm pot capsule (3) is overcome resistance that its ambient nitrogen formed and expanding, the instant impact that starting mode of pump produces is larger, then diaphragm pot capsule (3) expands larger, so effectively receive the water hammer produced because of starting mode of pump in water system, the hydraulic pressure of system is made to maintain a certain stable force value.Once water pump in water system out of service after, system loses pressure source, diaphragm pot capsule (3) internal pressure diminishes, the nitrogen of diaphragm pot capsule (3) outside will rely on the pressure originally gathered that the water in diaphragm pot capsule (3) is extruded in water system gradually by spherical plate (4), also diaphragm pot capsule (3) can be shifted onto the outlet of diaphragm pot (1) simultaneously, What is more can shift onto in water supply line by a part for diaphragm pot capsule (3), make it partially elongated thinning, be difficult to bear the pressure of nitrogen and burst.After adopting a kind of diaphragm pot capsule of the utility model patent guard shield; diaphragm pot capsule (3) is trapped in diaphragm pot delivery port flange (2) place, effectively prevents the pressure of nitrogen to be pushed in water supply line by diaphragm pot capsule (3).Also there will not be diaphragm pot capsule (3) to be elongated to draw thin and accident that is explosion, make diaphragm pot capsule (3) obtain good protection.
Claims (4)
1. a diaphragm pot capsule guard shield; it is characterized in that; the inner ring of the flange (6) connected with diaphragm pot delivery port flange welds the spherical plate (4) with hydraulic press punching, has been used for preventing diaphragm pot capsule (3) from being pushed in water supply line by the pressure of nitrogen and is burst by excessively drawing thin.
2., according to a kind of diaphragm pot capsule guard shield according to claim 1, it is characterized in that, described guard shield is the spherical plate that 4mm is thick.
3. according to a kind of diaphragm pot capsule guard shield according to claim 1, it is characterized in that, described spherical plate (4) has been bored the water-guiding hole (5) of several φ 5.
4. according to a kind of diaphragm pot capsule guard shield according to claim 1, it is characterized in that, when described spherical plate (4) is installed, its projection is facing to diaphragm pot.
