The sealing gasket of dress, is provided with spring between the core cap and sealing gasket, the spring housing is on the core bar.
Preferably, positioning sleeve, the height that spring described in precise control is compressed are provided between the pressure release core and core cavity.
Preferably, core print seat is provided between the core cap and sealing gasket, the core print seat is sleeved on the core bar, the spring
Between the core cap and core print seat, the core print seat is in contact with the sealing gasket, it is to avoid because of the spring and the sealing
Pad directly contact causes damage to the sealing gasket.
Preferably, the positioning sleeve internal diameter is not less than the core cap internal diameter, facilitates and is let out described in the positioning sleeve positioning
Pressure core.
Preferably, the sealing gasket diameter is less than the core cap internal diameter, facilitates electric power storage pool gas to discharge.
Preferably, the core print seat is set to " horn mouth " type, increases the core print seat and the contact area of the sealing gasket, makes institute
State sealing gasket stress evenly.
Preferably, the core cap outer surface is provided with screw thread, is set to be threadedly coupled between the pressure release core and core cavity, convenient to adjust
Save the compression height of the spring.
The beneficial effects of the utility model show：The utility model simple structure, it is easy to use, it is threadably secured,
The compression height of convenient control spring, the height compressed using positioning sleeve precise control spring makes to act on the bullet of sealing gasket
Spring force ensures, in a more accurate scope, so as to improve the uniformity of pressure release valve inside Opening pressure, to make pressure-relief explosion-proof
Effect is more reliable and more stable.

Specific embodiment
For the ease of it will be appreciated by those skilled in the art that being further described to the utility model below in conjunction with the accompanying drawings.
A kind of pressure release valve inside as shown in Figure 1-2, including pressure release core 1, the pressure release core 1 are arranged in core cavity 8, and it is special
Levying is, the pressure release core 1 includes core cap 4, and core bar 3 is inserted with the core cap 4, and the one end of the core bar 3 is provided with positioning table, described
The other end of core bar 3 is provided with the sealing gasket 7 of fixed installation, and spring 6,6 sets of the spring are provided between the core cap 4 and sealing gasket 7
On the core bar 3.
Positioning sleeve 2, the height that spring 6 described in precise control is compressed are provided between the pressure release core 1 and core cavity 8；It is described
Core print seat 5 is provided between core cap 4 and sealing gasket 7, the core print seat 5 is sleeved on the core bar 3, the spring 6 is arranged on the core
Between cap 4 and core print seat 5, the core print seat 5 is in contact with the sealing gasket 7, it is to avoid because of the spring 6 and the directly contact of sealing gasket 7,
The sealing gasket 7 is caused damage；The internal diameter of the positioning sleeve 2 is not less than the internal diameter of core cap 4, facilitates the positioning sleeve 2 to position
The pressure release core 1；The diameter of the sealing gasket 7 is less than the internal diameter of core cap 4, facilitates electric power storage pool gas to discharge；The core print seat 5 sets
It is " horn mouth " type, increases the core print seat 5 and the contact area of the sealing gasket 7, make the stress of the sealing gasket 7 evenly, carries
