Abstract
The utility model discloses an ultrahigh-pressure safety protection rupture valve which comprises a valve body (1) with an inlet, a pressure sleeve (7) with a discharge interface at the tail part and a valve core (5) clamping a safety protection rupture disk (3), and is characterized in that: the safety protection rupture disk (3) is fixedly connected to an axial channel port of the axial conical surface of the valve core (5) by a back cap (4) through a tail end taper hole of a clamping block (2) to form a safety protection rupture component, and is sealed between an ultrahigh-pressure medium channel and a low-pressure medium discharge channel; and when the rupture disk (3) ruptures, an ultrahigh-pressure medium enters a discharge pipeline through a discharge port of the pressure sleeve. In the utility model, the back cap is adopted to realize conical surface sealing through threaded connection among the clamping block, the safety protection rupture disk and valve core, and the clamping block is pressed on the valve body through the threaded connection between the pressure sleeve and the valve body so as to realize the sealing of the ultrahigh-pressure medium; and when the safety protection rupture disk ruptures, the ultrahigh-pressure medium is discharged through the discharge port of the pressure sleeve, thus a safety protection function is realized.
Description
Technical field
The utility model relates to a kind of ultrahigh pressure safety protection explosive valve that is mainly used on working pressure 100MPa or the above extra-high tension unit.
Background technique
Along with the continuous expansion of isostatic pressing technology application, macrotype isostatic pressing machine also increases thereupon.But the general floor space of macrotype isostatic pressing machine is very huge, and pipeline connects morely between each system, and the safety dumping of ultrahigh pressure medium is the important leverage that guarantees pipe-line system safety.
Summary of the invention
It is a kind of simple in structure that the purpose of the utility model is to provide, and is easy to install, and safe and reliable, volume is little, can realize and the direct-connected ultrahigh pressure safety protection of pipeline explosive valve.
The utility model solves the technological scheme that its technical problem adopted: a kind of ultrahigh pressure safety protection explosive valve; Comprise a valve body (1) that is provided with import, the gland (7) of an afterbody band discharging interface and the spool 5 of clamping security protection rupture disk (3); It is characterized in that; Described security protection rupture disk (3) passes through the tail end taper hole of grip block (2), is connected firmly on the axial passage port of the axial conical surface of said spool (5) by back of the body cap (4) and forms security protection explosion assembly, and be sealed between ultrahigh pressure medium channel (12) and the low pressure media discharge passage (13); When security protection rupture disk (3) when breaking, the ultrahigh pressure medium gets in the discharge pipe through gland (7) floss hole.
The utlity model has following beneficial effect.
Simple in structure, safe and reliable.The utility model superhigh pressure sealing all adopts the conical surface to seal firmly, and sealing configuration is reliable, and adopting is threaded bears the axial force that the ultrahigh pressure medium produces.
This practical ultrahigh pressure safety protection explosive valve can directly be installed on the pipeline; Superhigh pressure sealing adopts the hard seal form of the conical surface; Good sealing effect and safe and reliable, multiple spot are installed and can better be carried out safety protection to extra-high tension unit, have maintenance, safe characteristics.
Can be connected in easily on the various pipeline of macrotype isostatic pressing machine working line with this ultrahigh pressure safety protection explosive valve; Can be through the pipeline of security protection rupture disk explosion floss hole end connection; The ultrahigh pressure media discharge to the appointed place, is realized the safety protection function to isostatic press.
Description of drawings
Fig. 1 is the longitudinal sectional view of the utility model ultrahigh pressure safety protection explosive valve.
Among the figure: 1. valve body, 2. grip block, 3. security protection rupture disk, 4. back of the body cap, 5. spool, 6.O shape seal ring, 7. gland, 8. Leak hole, 9.
