Abstract
The utility model discloses an integration self-resuming formula pressure relief device. The sealing gland is tightly sealed at the upper top end of the lower cylinder body through a rubber sealing rubber ring, the plate type truncated cone volute spring is tightly pressed in the positioning sleeve, the positioning plates are fixed at the left end and the right end of the sealing gland, the positioning ring is fixed at the outer end of the upper part of the lower cylinder body, the lower end of the high-strength stud is fixed on the positioning ring, and the positioning plate is connected with the pressure rod through the adjusting nut for the positioning plate. Because the utility model discloses an elasticity take-up unit, when pressure exceeded normal numerical value, pressure relief device can open the discharge medium in the twinkling of an eye, carries out the pressure release to prevent that equipment superpressure from moving, improved equipment safe operation coefficient. When the pressure inside the equipment returns to normal, the self-recovery pressure relief device is automatically closed, a sealing effect is achieved, and normal operation of the equipment is guaranteed. And the structure is simple, the production cost is low, and the sealing and pressure relief effect is good.
Description
The technical field is as follows:
the utility model belongs to the technical field of the environmental protection and specifically relates to an integration self-resuming formula pressure relief device that top, lateral part, import and export pipeline used suitable for electrostatic precipitator, wet electric precipitator, bag collector.
Background art:
with the increasing development of modern industrial technology, the polluting smoke generated in the process of energy utilization brings serious harm to the ecological environment and human life, thereby promoting the rapid development of dust removal equipment. The production quality of the existing dust removing equipment is uneven, and due to the design defects and the operation factors, the phenomenon of overpressure operation often occurs, so that safety accidents are easily caused. Most of the pressure relief devices of the existing dust removing equipment have complex structures, higher cost and poor pressure relief effect.
The utility model has the following contents:
the utility model aims to solve the technical problem that an adopt elasticity take-up mechanism is provided, when pressure exceeded normal numerical value, pressure relief device can open the discharge medium in the twinkling of an eye, carries out the pressure release to prevent equipment superpressure operation, improve equipment safe operation coefficient. When the pressure inside the equipment returns to be normal, the self-recovery type pressure relief device is automatically closed, the sealing effect is achieved, the normal operation of the equipment is guaranteed, the structure is simple, the production cost is low, and the sealing pressure relief effect is good.
The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: the sealing gland of the integrated self-recovery pressure relief device is tightly sealed at the upper top end of the lower cylinder body through a rubber sealing rubber ring, the plate type truncated cone volute spring is tightly pressed in the positioning sleeve, the positioning sleeve is fixed in the middle of the upper portion of the sealing gland, the positioning plates are fixed at the left end and the right end of the sealing gland, the positioning ring is fixed at the outer end of the upper portion of the lower cylinder body, the lower end of the high-strength stud is fixed on the positioning ring, the positioning plate is connected with the pressure rod through the adjusting nut for the positioning plate, and the pressure relief opening pressure of the plate type truncated cone volute spring is adjusted through the adjusting nut for the pressure rod to close the valve body.
The utility model has the advantages that: due to the adoption of the elastic tightening mechanism, when the pressure exceeds a normal value, the pressure relief device can instantly open the discharged medium to relieve the pressure, so that the equipment is prevented from running at overpressure, and the safe running coefficient of the equipment is improved. When the pressure inside the equipment returns to normal, the self-recovery pressure relief device is automatically closed, a sealing effect is achieved, and normal operation of the equipment is guaranteed. And the structure is simple, the production cost is low, and the sealing and pressure relief effect is good.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a top view of fig. 1.
The specific implementation mode is as follows:
example 1: as shown in fig. 1 and 2, a sealing gland 2 of the integrated self-recovery pressure relief device is tightly pressed and sealed at the top end of a lower cylinder 5 through a rubber sealing rubber ring 1, a plate-type truncated cone volute spring 4 is tightly pressed in a positioning sleeve 10, the positioning sleeve 10 is fixed at the upper middle part of the sealing gland 2, positioning plates 8 are fixed at the left end and the right end of the sealing gland 2, a positioning ring 9 is fixed at the outer end of the upper part of the lower cylinder 5, the lower end of a high-strength stud 6 is fixed on the positioning ring 9, the positioning plate 8 is connected with an adjusting nut 7 and a pressure lever 3 through the adjusting nut 7, and the pressure relief opening pressure of the plate-type truncated cone volute spring 4 is adjusted through the pressure lever 3 to close a valve body.
Example 2: as shown in fig. 1 and fig. 2, the rubber gasket 1 of the integrated self-recovery pressure relief device has a shore a hardness of 65.
Example 3: as shown in fig. 1 and 2, the high-strength stud 6 of the integrated self-recovery pressure relief device is a double-ended stud.
Example 4: the utility model discloses a theory of operation does:
this device built-in spring, equipment normal operating, integration self-resuming formula pressure relief device relies on its built-in spring's pulling force to take up its gland on self-resuming formula pressure relief device's flange, play airtight effect, when equipment internal pressure is greater than the elasticity of spring, pressure relief device's gland is backed up open, thereby release away the inside high-pressure gas, obtain the purpose of pressure release, when equipment inside pressure returns normally, self-resuming formula pressure relief device closes, play the sealing effect.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
