Abstract
The invention discloses a pressure container with a safety valve. A cylindrical installation groove is formed in the top part of the pressure container; the top part of the installation groove is opened; a vent hole is formed in the bottom part of the installation groove; the installation groove is communicated with the interior of the pressure container through the vent hole. A valve cover and a spring are arranged in the installation groove; a vent hole is formed in the valve cover; the side wall of the valve cover is in threaded connection with the side wall of the upper part of the installation groove. The upper end of the spring is movably connected with the bottom face of the valve cover; the lower end of the spring sleeves outside a spring plunger of a valve core, and is movably connected with a sealing fin. The pressure container with the safety valve has the recovery function, and the internal pressure of the pressure container can be controlled within a set range; when the internal pressure of the pressure container is increased, redundant air can be exhausted outside the pressure container in time, so that the safety of the pressure container is ensured; when the internal pressure of the pressure container is recovered to a specified value, the safety valve can be closed in time.
Description
Technical field
The present invention relates to a kind of container, be specifically related to a kind of pressurized container being provided with safety valve.
Background technique
Pressurized container of the prior art, refers to filling gas or liquid, the Sealing Arrangement of carrying certain pressure.The purposes of pressurized container is very extensive.It is the equipment all played an important role in each department of the national economy such as petrochemical industry, energy industry, scientific research and military project.Pressurized container generally by cylindrical shell, end socket, flange, seal element, perforate and adapter, bearing etc. six major part form vessel.In addition, be also furnished with safety installations, show to take into account the internals of complete various processes effect.Pressurized container, due to reasons such as sealing, pressure-bearing and media, is easily blasted, is burnt on fire and jeopardize personnel, equipment and the safety of property and the accident of befouling environment.At present, countries in the world are all classified as important prison inspection product, and the specialized agency specified by country, implements supervision and check and technical checking according to the rule and standard of national regulation.
Summary of the invention
For the deficiency that prior art exists, the invention provides a kind of pressurized container being provided with safety valve.
To achieve these goals, the present invention realizes by the following technical solutions:
A kind of pressurized container being provided with safety valve of the present invention, is characterized in that: comprise valve gap, spring and spool; Offer mounting groove at the top of pressurized container, the open-top of mounting groove, bottom has exhaust port, and mounting groove is communicated with by exhaust port with pressurized container inside; Described valve gap and spring are arranged in mounting groove, wherein valve gap have air outlet hole, and the sidewall of described valve gap is threaded with the upper portion side wall of mounting groove; Described spool comprises spring holder, the diaphragm seal of tablet, adjustment pin three part of rounding stage body of cylinder from top to bottom successively, and the lower surface area of diaphragm seal part is greater than the upper surface area of adjustment pin part; Described spool is one-body molded, and the upper end of described spring is flexibly connected with the bottom surface of valve gap, and the lower end of spring is enclosed within outside the spring holder of spool, and is flexibly connected with diaphragm seal; The underrun conical surface transition of described exhaust port and mounting groove, the tapering of this conical surface is consistent with the tapering of the outer side surface of the adjustment pin part of spool.
Above-mentioned spring adopts stainless steel material.
Beneficial effect of the present invention: the present invention has can restore funcitons, can by pressure-controlled in pressurized container in the scope of setting, when vessel internal pressure increases, can in time by outside unnecessary gas discharge pressure container, and the Security of guarantee pressurized container; When pressure in pressurized container returns to the value of regulation, safety valve then can close again in time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
As shown in Figure 1, a kind of pressurized container being provided with safety valve, offer columniform mounting groove 2 at the top of pressurized container 1, the open-top of mounting groove 2, bottom have exhaust port 7, and mounting groove 2 is communicated with by exhaust port 7 with pressurized container inside.
Valve gap 3 and spring 5 are arranged in mounting groove 2, wherein valve gap 3 have air outlet hole 4, and the sidewall of valve gap 3 is threaded with the upper portion side wall of mounting groove 2.
Spool 6 is formed in one structure, and spool 6 comprises cylindrical spring holder 6, the diaphragm seal of disc, adjustment pin three part of rounding stage body from top to bottom successively.
The upper end of spring 5 is flexibly connected with the bottom surface of valve gap 3, and the lower end of spring 5 is enclosed within outside the spring holder of spool 6, and is flexibly connected with diaphragm seal, and the two ends of spring 5 prop up the bottom surface of valve gap 3 and the upper surface of diaphragm seal respectively.
More than show and describe basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof
.
