Abstract
The invention discloses a low-temperature safety valve, which comprises a valve body, a valve clack arranged in the valve body, an adjusting block arranged at a liquid outlet end in the valve body, and a spring arranged between the valve clack and the adjusting block, wherein a valve hole running through the valve body is formed in the valve body; a valve clack stopping surface is arranged on the valve hole; the liquid inlet end of the valve clack is provided with a blind hole; the periphery of the bottom part of the blind hole wall is uniformly provided with radial flow guide holes; the liquid inlet end of the valve clack is provided with a stopping step; a sealing ring is arranged on the stopping step; the middle part of the valve clack is provided with a radial through hole; the liquid outlet end of the valve clack is provided with a liquid outlet hole communicated with the radial through hole; the liquid outlet hole of the valve clack and an axial through hole of the adjusting block are provided with a spring positioning step surface respectively; and a blind hole liquid inlet of the valve clack is provided with a filter screen. Because the blind hole liquid inlet of the valve clack of the safety valve is provided with the filter screen to hold up garbage in a pipeline, the safety valve can be effectively sealed after taking off, and then the service life of the safety valve is prolonged, and the economic losses caused by gas leakage are avoided.
Description
Technical field
The present invention relates to a kind of low-temperature safety valve.
Background technique
The low-temperature safety valve be applied to and all kinds of cryogenic pipe in; When the cryogenic gas in the low-temperature pressure container pipeline surpasses certain rating value; The low-temperature safety valve can be opened automatically, exhausting air, thus reach the purpose of pressure release; Pressure in pipeline and the low-temperature (low temperature) vessel is remained in the safety range, carry out with the safety of guaranteeing all kinds of productions.Common low-temperature safety valve occurs sometimes that the rubbish in the pipeline gets in the valve body after the flap take-off in use, causes safety valve fully not seal and leaks.
Summary of the invention
Technical problem to be solved by this invention is: provide after a kind of take-off can effective seal the low-temperature safety valve.
In order to solve the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of low-temperature safety valve comprises: valve body, be arranged on flap in the valve body, be arranged on the regulating block of outlet end in the valve body and be arranged on flap and regulating block between spring; Two ends of valve body is respectively arranged with connecting thread; Be provided with the valve opening that connects valve body in the valve body, valve opening is provided with the flap stop surface, is provided with axial hole in the regulating block; Described flap liquid feeding end is provided with blind hole; The blind pore wall bottom circumferentially evenly is provided with radially pod apertures, and the flap liquid feeding end is provided with stopping step, and stopping step is provided with seal ring; The flap middle part is provided with radial direction through hole; The flap outlet end is provided with the liquid outlet opening that connects with radial direction through hole, is respectively arranged with spring positioning table terrace on the liquid outlet opening of said flap and the axial hole of regulating block, and the liquid entering hole of the blind hole of said flap is provided with filter screen.
Described valve body adjusted piece mounting point part is provided with pin-and-hole, is provided with the pin that is used for positioning adjust block in the pin-and-hole.
Described valve body is provided with relief hole.
Advantage of the present invention is: owing to be provided with filter screen at the blind hole liquid entering hole of safety valve flap; Live the interception of the rubbish in the pipeline; Making behind the safety valve jumping up can effective seal, thereby has prolonged the working life of safety valve, the economic loss of having avoided gas leakage to cause.

Embodiment
Describe particular content of the present invention in detail below in conjunction with accompanying drawing and specific embodiment.
Like Fig. 1, shown in Figure 2, a kind of low-temperature safety valve comprises: valve body 1, be arranged on flap 3 in the valve body 1, be arranged on the regulating block 2 of outlet end in the valve body 1 and be arranged on flap 1 and regulating block 2 between spring 4; The two ends of valve body 1 are respectively arranged with connecting thread 11; Be provided with the valve opening 12 that connects valve body 1 in the valve body 1, valve opening 12 is provided with flap stop surface 13, is provided with axial hole 21 in the regulating block 2; Described flap 3 liquid feeding ends are provided with blind hole 31; Blind hole 31 walls bottom circumferentially evenly is provided with radially pod apertures 32, and flap 3 liquid feeding ends are provided with stopping step 33, and stopping step 33 is provided with seal ring 5; Flap 3 middle parts are provided with radial direction through hole 34; Flap 3 outlet ends are provided with the liquid outlet opening 35 that connects with radial direction through hole 34, are respectively arranged with spring positioning table terrace on the liquid outlet opening 35 of said flap 3 and the axial hole 21 of regulating block 2, and the liquid entering hole of the blind hole 31 of said flap 3 is provided with filter screen 6.
Described valve body 1 adjusted piece 2 mounting point parts are provided with pin-and-hole 14, are provided with the pin 7 that is used for positioning adjust block 2 in the pin-and-hole 14.
Described valve body 1 is provided with relief hole 15.
When manifold pressure during greater than setting pressure, flap 3 makes the low-temperature safety valve open pressure release at pressure action of medium lower compression spring 4, and after pressure reduced, flap 3 is returning position under spring 4 elastic force effects again, and the low-temperature safety valve cuts out.
Owing to be provided with filter screen 6 at blind hole 31 liquid entering holes of safety valve flap 3, live the interception of the rubbish in the pipeline, making behind the safety valve jumping up can effective seal, thereby has prolonged the working life of safety valve, has avoided gas leakage to cause economic the damage.
