Abstract
The utility model relates to a shearing blasting piece device, which is a security and protection device most preferred in the pressure bearing system with the relatively stable blasting pressure. The device is composed of a rotary plug; the clamping ring, the blasting piece and the gasket ring are orderly arranged on the inner side of one end of the rotary plug. The tests have proven that the blasting pressure is stable, that the performance is reliable, that the relief area can be 100 percent and that the sheared part will flee away completely; thus the utility model can realize the purpose of the rapid pressure relief; the utility model has the advantages of simple structure, good sealing performance and so on, and is conducive to the promotion and application.
Description
Technical field
The utility model relates to a kind of pressurized system safety protection device, relates in particular to a kind of shearing type blasting piece device; It is safety protection device first-selected in the metastable pressurized system of requirement bursting pressure.
Background technique
In the past such as oil; in the production process in fields such as chemical industry; the operation that has is to finish in the system of High Temperature High Pressure; for guaranteeing this system safety operation; often in this system, install blasting piece device; when pressurized system surpasses scheduled pressure value; the blasting piece device explosion; make the pressurized system pressure release; thereby make pressurized system obtain protection; for positive effect has been brought into play in safety in production; however, along with the development that science and technology is maked rapid progress, the improving constantly of industrialization degree; performance to blasting piece device is also had higher requirement; if any pressurized system just require not only the forward can explosion, and oppositely also can explosion during superpressure, so the two-way shot device just occurred.And for example pulled open the medium state that the type rupture disk is applicable to gaseous state, liquid state and gas-liquid coexistence in the past, but be subjected to the influence of material thickness and attribute own, make it have the unsettled drawback of bursting pressure, and then the safety in production needs of the metastable pressurized system of bursting pressure that just can not meet the demands.
The model utility content
The utility model is at above-mentioned problems of the prior art, provide that a kind of bursting pressure is stable, reliable performance, simple in structure, discharge area big and be subjected to material thickness and properties affect own is little, the shearing type blasting piece device of good airproof performance.
To achieve these goals, the technical solution of the utility model is as follows:
Be made up of cock, its carrier ring, rupture disk and gasket ring are loaded on the inboard of cock one end successively.
The inner edge of described carrier ring and rupture disk surface of contact is the right angle type that is beneficial to shearing.
When described rupture disk was loaded on the pressurized system by cock, its periphery was to be to be held ring and gasket ring impaction state.
The utility model has the advantages of as follows:
The utility model compared with prior art, owing to adopted carrier ring, rupture disk and gasket ring be loaded on the inboard with externally threaded cock one end successively, simultaneously the inner edge of carrier ring and rupture disk surface of contact is made a series of technical measures such as right angle that are beneficial to shearing, and through evidence have that bursting pressure is stablized, the reliable performance discharge area reaches 100% and is sheared the fly out purpose of realization quick pressure releasing of part integral body; Advantages such as simple in structure, good airproof performance are beneficial to and apply.
Description of drawings
Fig. 1 is a plan view structural representation of the present utility model.
Fig. 2 is a carrier ring structural representation of the present utility model.
Among the figure, 1, cock, 2, carrier ring, 3, gasket ring, 4, rupture disk, arrow is represented pressure direction.
Embodiment
Embodiment
Embodiment of the present utility model is described in detail in conjunction with the accompanying drawings, as shown in Figure 1, 2, it in it outer helicoid cock 1 of hexagonal hole, annular shoulder is processed in one end inboard, carrier ring 2, rupture disk 4 and gasket ring 3 outwards are loaded on an end of cock 1 successively from the lining, the another side of assembling back gasket ring 3 protrudes the end face that cock 1 should be held; Described carrier ring 2 is through machine shaping with lead brass, and will be processed into the right angle type that is beneficial to shearing with the inner edge of rupture disk surface of contact, rupture disk 4 be by Stainless Sheet Steel through machine shaping, when installing to pressurized system by cock 1, its periphery is and is held ring 2 and gasket ring 3 impaction states.
When the utility model used, when the place pressurized system surpassed scheduled pressure value, the inner edge wedge angle that rupture disk 4 is held ring 2 cut off, and is cut off part integral body and flies out from cock 1, reaches the purpose of quick moment pressure release, and then has protected pressurized system.
Claims (3)
1, a kind of shearing type blasting piece device is made up of cock (1), it is characterized in that carrier ring (2), rupture disk (4) and gasket ring (3) are loaded on the inboard of cock (1) one end successively.
