Description
Technical field
The utility model relates to a kind of fire-fighting container class decompression anti-explosion device, especially a kind of adjustable spring pressure is let out
Put safety valve.
Background technique
In security against fire field, pressure in order to prevent inside high-pressure bottle equipment is excessive to be caused to rupture or explode, and is needed
Safety valve is set.Safety valve can be divided into closed and Unseal type at present, for air and steam safety valve, mostly use not
Pessimistic securit valve.Selection for Unseal type safety valve product should determine have at present in the market by practical sealed pressure
Using spring loaded safe valve, but the safety valve internal structure is complex, and spring base and valve seat generate work
It is firmly transmitted by steel ball, valve inner is labyrinth type coupling sealing, reaches sealing effect by multiple component combinations, safeguards not side
Just, encountering some corrosive gas can make safety valve leakproofness be affected.
Utility model content
Purpose of utility model: the purpose of this utility model is that in view of the deficiencies of the prior art, it is adjustable to provide a kind of spring
Formula pressure releasing safety valve, internal structure is simple, and pressure release mode is direct, easy to maintain, permanent durable.
Technical solution: in order to reach above-mentioned purpose of utility model, the utility model is specifically achieved like this, a kind of bullet
Spring adjustable pressure is released safety valve, including valve casing and spool, and the spool is mounted on inside valve casing, which is characterized in that described
Valve casing includes that pressure-releasing chamber, the valve housing side wall on valve casing top are provided with outer pressure relief opening, the air inlet for being connected to pressure-releasing chamber is arranged at valve casing lower part.Institute
State spool include valve core, spool body sidewall be provided with interior pressure relief opening, the spring being placed on inside valve core, spring lower part convex
Tabletting.Container inner pressure is transmitted to spring, carries out pressure release at any time by spring.
Further, it is equipped with plush copper at the top of the spool, plush copper is threadedly coupled with spool.Pass through plush copper adjustable springs
Pressure size, so that the pressure in container be adjusted.
Further, interior hexagonal counterbore is equipped at the top of the plush copper.Die nut is facilitated to operate.
Further, it is connected through a screw thread between the valve casing and spool.It is easy to assembly.
Further, the outer pressure relief opening and interior pressure relief opening are overlapped and be respectively distributed to two of valve casing and valve core
Side, and outer pressure relief opening diameter is greater than interior pressure relief opening diameter.Quick pressure releasing dissolution medium.
Further, the convex tabletting has gasket.Outer pressure relief opening and interior pressure relief opening are adjusted by spacer thickness
Highly.
Further, it is sealed between the pressure-releasing chamber and air inlet by O-ring.Sealing effect is good, and maintenance cost is low.
Further, the valve casing lower part is equipped with external screw thread.It is connect by external screw thread with tankage.
Further, the valve casing and spool material are metal, are preferred with stainless steel material.Antirust, anticorrosion is good.
The utility model has the advantages that the utility model compared with traditional technology, has the advantage that
1. by the pressure size of the adjustable spring of plush copper at the top of spool, so as to be carried out to container internal pressure
Adjustment.
2. outer pressure relief opening and interior pressure relief opening it is each there are two, can to the medium in container carry out quick pressure releasing.
3. preferred stainless steel material, antirust, corrosion resistance are good, long service life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of safety valve.
Fig. 2 is the valve casing structural schematic diagram of safety valve.
Fig. 3 is the valve core structure schematic diagram of safety valve.
Fig. 4 is the gasket main view of safety valve.
Specific embodiment
Embodiment 1: as shown in Figure 1, a kind of structural schematic diagram of adjustable spring pressure releasing safety valve, including valve casing 1
With spool 2, the spool 2 is mounted on inside valve casing 1, and the valve casing 1 includes that pressure-releasing chamber 1.1, the valve housing side wall on valve casing top are opened
There are outer pressure relief opening 1.3,1 lower part of valve casing to have the air inlet 1.2 of connection pressure-releasing chamber 1.3.The spool 2 includes valve core 2.1, spool
2.1 side wall of body is provided with the convex tabletting 2.3 of interior pressure relief opening 2.5, the spring 2.2 being placed on inside valve core, spring lower part, peace
Full valve Fig. 1 is split as valve casing Fig. 2 and spool Fig. 3, and there is external screw thread in 1 lower part of valve casing, directly can pass through spiral shell with high-pressure bottle
Line connection, the spool 2 have gasket 2.4 below convex tabletting 2.3, and gasket 2.4 is equipped with chamfering 2.4.1 and is convenient for convex tabletting
2.3 protrusion is passed through the centre bore 2.4.2 of gasket 2.4, gasket 2.4 and 1 junction of valve casing and is sealed using O-ring 2.8, valve
There is the plush copper 2.6 of threaded connection at the top of core 2, offers interior hexagonal counterbore 2.7 at the top of plush copper, using allen wrench, pass through rotation
The decrement for twisting plush copper adjustment spring, to indirectly be adjusted to the pressure inside high-pressure bottle.
Safety valve is mounted on high-pressure bottle by external screw thread 1.4, once high-pressure bottle internal pressure is excessive, oppresses convex
Tabletting 2.3, pressure are transmitted to spring 2.2 upwards by convex tabletting 2.3, move up convex tabletting 2.3, are detached from gasket 2.4 and O
The sealing structure region that type circle 2.8 forms, medium enter the space inside valve core along the direction that convex tabletting 2.3 is displaced,
Successively by interior pressure relief opening 2.5 and outer pressure relief opening 1.3 outwardly dissolution medium, to achieve the effect that pressure release, high-pressure bottle exists
Internal pressure reduces after discharging a part of medium, and compressing force is greater than container internal pressure to spring 2.2 at this time, again convex tabletting
2.3 push back original position, and high-pressure bottle reseals.
Whole device material is stainless steel, and antirust, long service life, dissolution medium is rapid, and internal structure is relatively easy,
Conducive to disassembling and maintaining.
