Description
Technical field
The utility model relates to a kind of low pressure vessel, is meant a kind of vertical gas holder especially.
Background technique
Pressurized container is meant and is used for splendid attire gas or liquid, and needs the Sealing Arrangement of carrying certain pressure.Pressurized container is widely used in numerous areas such as oil, chemical industry, space flight and medical treatment.It is divided into according to the grade of bearing pressure: low pressure vessel, medium pressure vessel, high-pressure bottle and ultrahigh pressure vessel.The vertical gas holder of low pressure is comparatively common in the pressurized container; and what be most widely used is a kind of; in order to remove impurity and the oxide in the tank body comparatively easily, can offer the services aperture that is used for regular maintenance in the bottom of tank body usually, and services aperture is provided with seal arrangement.Services aperture can be sealed up by closing seal arrangement during use, when needs clean, just seal arrangement be opened, clean then.Existing sealing device structure is often comparatively complicated, and its dismounting comparatively bothers, and sealing effect is not very desirable.
The model utility content
The utility model provides a kind of low pressure vertical gas holder, and its purpose is to overcome the seal arrangement dismounting trouble that prior art exists, the defective that sealing effect is not good enough.
The technical solution of the utility model is as follows:
The vertical gas holder of low pressure, comprise the tank body of making by stainless steel, be located at the tank body bottom services aperture and with the suitable seal arrangement of services aperture, described seal arrangement comprises the sleeve that is welded in the services aperture periphery, the shape of this sleeve and size are suitable with services aperture, and an end of sleeve is positioned at the inboard of tank body, the other end is positioned at the outside of tank body, described seal arrangement also comprises sealing cover, seal washer, bolt and shore, the exterior edge face of sleeve and shore butt, one end butt of the interior edge face of sleeve and seal washer, the other end of seal washer and sealing cover butt, and be connected with nut by screw rod between described sealing cover and the shore, nut is positioned at the outside of tank body.
As improvement of the present utility model, the shape ovalize of described services aperture.
As further improvement of the utility model, the ratio of the major axis of described service hatch and minor axis is 3.5:1.
Further improve as of the present utility model, described bolt is arranged in the middle part of sealing cover and shore.
Further improve as of the present utility model, the inside and outside surface of the outer surface of described tank body and sleeve is coated with the water-based enamelled coating.
Compared with prior art to description of the present utility model as can be known by above-mentioned, advantage of the present utility model is:
1, seal arrangement dismounting of the present utility model is comparatively convenient, and its sealing effect is comparatively desirable, during use, only needs nut is screwed, and just can make seal arrangement have good sealing effect; When needs clean,, just can easily take off sealing cover, and clean effectively as long as nut is unscrewed.
2, the ratio of the major axis of services aperture and minor axis is 3.5:1, is consistent with the structure of human hands, is suitable for the staff hand is stretched in the gas holder.
3, the fluid in the gas holder tends to the madial wall of gas holder is caused certain pressure, the direction of this pressure outwardly, it can impel sealing cover to be pressed in seal washer and sleeve, thereby reaches better sealing effect.
4, the water-based enamelled coating can be protected tank body and sleeve effectively; In addition, do not contain harmful matters such as formaldehyde, benzene, dimethylbenzene in the water paint, so water paint almost do not have atmospheric pollution, it is environmental protection comparatively.
5, the tank body made of stainless steel is difficult for getting rusty, and working life is longer.
