Compared with the prior art, the special blasting plate device is compact in structure and easy in installation, is portable, is particularly applicable to long pipe trailers, and has the advantages of large relief area, quick response speed, low cost, compact structure, fine sealing performance and the like as compared with a safety valve with the same aperture.
Description
Technical field
The utility model relates to a kind of rupture disk safety installations, especially relates to the special-purpose blasting piece device of long-tube trailer.
Background technique
The rupture disk safety installations is by pressure differential, non-automatic urgent pressure relief device of cutting out, and is mainly used in protection pressurized container, pipeline or other closed system, and it is avoided because of excessively superpressure or vacuum cause destroying.The rupture disk safety installations has been widely used in the equipment that industries such as chemical industry, medicine, environmental protection, iron and steel, electric power need protection now.
Gas cylinder pressure release on the long-tube trailer, method in the past are at bleed outlet safety valve to be installed, and the hydrodynamic pressure in gas cylinder reaches or when being higher than the setting cracking pressure value of safety valve, safety valve can be opened automatically for a certain reason and unusual the rising.But for the safety valve safety valve of metallic sealing section particularly, reach does not have fully that to leak be difficulty very, and the leakage of safety valve means the lasting loss of medium.Certainly; The same rupture disk of safety valve, fusible plug etc. can only be expendable pressure releasing means different; Be a kind of can nonexpondable " reclosing formula " pressure releasing means; This is the advantage of safety valve, but safety valve reseals than keeps existing sealing state difficulty more after opening.In order to address these problems, satisfy market and user's needs, must invent the safety installations of a kind of compact structure, favorable sealing property.
The model utility content
The purpose of the utility model is exactly for the defective that overcomes above-mentioned existing technology existence a kind of compact structure, the special-purpose blasting piece device of light, easy-to-install long-tube trailer to be provided.
The purpose of the utility model can realize through following technological scheme:
The special-purpose blasting piece device of long-tube trailer; It is characterized in that; This blasting piece device comprises right arch cutting type rupture disk, gasket seal, pressure ring, first joint, second joint, fusible plug, rainproof pad and valve seat, and described domed rupture disk is installed between gasket seal and the pressure ring, and valve seat is connected with first joint screw thread; First joint is connected with second joint screw thread; Fusible plug is fixed on first joint, and right arch cutting type rupture disk, gasket seal and pressure ring are between the valve seat and first joint, and rainproof pad is between first joint and second joint.
Described rupture disk is a pressure control valve, and pattern is a right arch cutting type, and radial direction has the groove of wearing 4 non-quarters on the diaphragm arch face, and to reduce diaphragm intensity, during the rupture disk explosion, diaphragm is torn along groove, reaches the purpose of relieving pressure.
Described first joint and second joint are with valve seat and are threaded, and are easy to install and dismounting, and be simple in structure.
On first joint, fusible plug is installed, when reaching setting temperature, the fusible plug fusion.
Compared with prior art; The utility model compact structure, light, be easy to install; Be particularly useful for long-tube trailer, compared to the safety valve of same bore, have that discharge area is big, reaction velocity is fast, an advantage such as with low cost, compact structure, favorable sealing property.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
The special-purpose blasting piece device of long-tube trailer, its structure is as shown in Figure 1, and the each several part structure is shown in Fig. 2-8.Blasting piece device is made up of right arch cutting type rupture disk 1, gasket seal 2, pressure ring 3, first joint 4, second joint 5, fusible plug 7, rainproof pad 6 and valve seat 8.Right arch cutting type rupture disk 1 is installed between gasket seal 2 and the pressure ring 3; Valve seat 8 is threaded with first joint 4; First joint 4 is threaded with second joint 5; Fusible plug 7 is fixed on first joint 4, and right arch cutting type rupture disk 1, gasket seal 2 and pressure ring 3 are between the valve seat 8 and first joint 4, and rainproof pad 6 is between first joint 4 and second joint 5.The interface size that valve seat 8 is connected with gas cylinder can be harmonized according to cylinder interface, generally selects for use tapered thread to connect, and guarantees the sealing between valve seat 8 and the gas cylinder.The bursting pressure of package unit is by 1 control of right arch cutting type rupture disk, and radial direction has the groove of wearing 4 non-quarters on the diaphragm arch face, to reduce diaphragm intensity; During the rupture disk explosion; Diaphragm is torn along groove, reaches the purpose of relieving pressure, and advantage is the stable and good seal performance of relieving pressure.When temperature reaches the design temperature of fusible plug 7, fusible plug 7 fusing, and the pressure of device is when reaching bursting pressure, the gas cylinder pressure release.Therefore, when having only the design bursting pressure and the temperature that reach rupture disk when the pressure in the gas cylinder cavity to reach the melting temperature of fusible plug 7, just pressure release of package unit.
