Abstract
The utility model relates to an explosion-proof bottom housing for a shock-resistant oil-charged pressure gauge. The explosion-proof bottom housing is characterized by comprising a housing with the rear part opened and a rear cover pressed into the opening at the rear part of the housing, wherein the rear cover and the housing are connected to form an inner chamber for the shock-resistant oil-charged pressure gauge. The explosion-proof bottom housing has a simple structure, is convenient to assemble, and can effectively prevent pressure, which is caused after internal fittings are damaged when a superpressure load occurs in the shock-resistant oil-charged pressure gauge, from impacting operators in front, thereby protecting the operators against injury. Besides, the explosion-proof bottom housing can effectively achieve pressure relief, thereby protecting normal operation and prolonging the service life of the shock-resistant pressure gauge.
Description
Technical field
The utility model relates to a kind of antidetonation oil dumped pressure gauge, especially relates to the explosion-proof drain pan of a kind of antidetonation oil dumped pressure gauge, belongs to tensimeter blast resistance construction technical field.
Background technology
The antidetonation oil dumped pressure gauge is that common measurement instruments is gone up in industry; Be widely used in every field, at present the antidetonation oil dumped pressure gauge is in use as when the over pressure load operation occurring, and the inner elastomeric element very easily damages; Cause the elevated pressures abrupt release inner to the antidetonation oil dumped pressure gauge; And antidetonation oil dumped pressure gauge inside is the structure that seals fully, so pressure can impact the instrument glass or the plastic cover of weak pre action personnel reading numerical values, hurts sb.'s feelings after the breakage.
The utility model content
Be to solve the deficiency of prior art, the purpose of the utility model is to provide a kind of simple in structure, effectively release, the explosion-proof drain pan of antidetonation oil dumped pressure gauge that explosion-proof effect is good.
For achieving the above object, the utility model is to realize through following technical scheme:
The explosion-proof drain pan of a kind of antidetonation oil dumped pressure gauge is characterized in that, comprises that the shell and of a rear aperture is pressed into the bonnet at shell rear aperture position, and described bonnet and shell are connected to form the inner chamber of antidetonation oil dumped pressure gauge.
The contact jaw of the inner chamber of described bonnet and antidetonation oil dumped pressure gauge also is provided with seal membrane.And the material of described seal membrane is a rubber.Rubber better elastic performance can reduce the compression shock that bonnet receives, because bonnet and shell are split-type structurals, can open bonnet from behind, carries out release, thereby can effectively avoid pressure to discharge from the front personnel is damaged.
In addition, the front portion of described shell also is provided with bursting diaphragm, and described bursting diaphragm is arranged between the face glass of instrument and instrument front on the antidetonation oil dumped pressure gauge.When antidetonation oil dumped pressure gauge interior fittings was damaged, the pressure of abrupt release can not damage the glass or the plastic cover of instrument front through the obstruction of bursting diaphragm.
The beneficial effect of the utility model is: the utility model is simple in structure, easy to assembly; In the time of can effectively preventing the appearance over pressure load in the antidetonation oil dumped pressure gauge; The operating personnel of compression shock front, interior fittings damage back damage operating personnel, and can carry out release effectively; Protect the normal operation of anti-shock pressure meter, prolonged its serviceable life.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
The main mark implication is following in the accompanying drawing:
1, shell 2, bursting diaphragm 3, bonnet 4, seal membrane.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done concrete introduction.
Fig. 1 is the structural representation of the utility model one embodiment.
As shown in Figure 1: the explosion-proof drain pan of a kind of antidetonation oil dumped pressure gauge, comprise that the shell 1 and of a rear aperture is pressed into the bonnet 3 at shell 1 rear aperture position, described bonnet 3 and shell 1 are connected to form the inner chamber of antidetonation oil dumped pressure gauge.Be provided with interior fittings and instrument of antidetonation oil dumped pressure gauge etc. in the said inner chamber.The utility model is a split-type structural through the enclosure designs with the antidetonation oil dumped pressure gauge; Can carry out release through bonnet 3; With the shell that prevents traditional antidetonation oil dumped pressure gauge is an integral sealing formula structure; Make pressure to lay down, cause the interior fittings of antidetonation oil dumped pressure gauge to damage and injure operating personnel's situation easily.
In addition, described bonnet 3 also is provided with seal membrane 4 with the contact jaw of the inner chamber of antidetonation oil dumped pressure gauge.And the material of described seal membrane 4 is a rubber.Rubber better elastic performance can reduce the compression shock that bonnet 3 receives, because bonnet 3 is a split-type structural with shell, can open bonnet 3 from behind, carries out release, thereby can effectively avoid pressure to discharge from the front personnel is damaged.
In addition, the front portion of described shell 1 also is provided with bursting diaphragm 2, and described bursting diaphragm 2 is arranged between the face glass of instrument and instrument front on the antidetonation oil dumped pressure gauge.When antidetonation oil dumped pressure gauge interior fittings is damaged; The pressure of abrupt release can not damage the glass or the plastic cover of instrument front, and then can not hurt the operating personnel of front through the obstruction of bursting diaphragm 2; Increase security, prolonged the serviceable life of antidetonation oil dumped pressure gauge.
The foregoing description does not limit the utility model in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in the protection domain of the utility model.
Claims (4)
