Description
Technical field
The utility model is related to a kind of spring micro-open type safety valve, specifically a kind of for media such as steam, air
Equipment or pipeline on spring micro-opening formula safety, belong to valve kind equipment technical field.
Background technology
In the prior art, it is general in the equipment or pipeline of conveying steam and air dielectric that valve is set, by opening for valve
Open the break-make conveyed with closing control gas medium.When the gas pressure in standby or pipeline is excessive, security incident can be produced, because
This needs sets safety valve on pipeline, and pressure is discharged when channel interior pressure is excessive.
The content of the invention
The purpose of this utility model is to overcome above-mentioned weak point, so as to provide a kind of spring micro-open type safety valve, energy
It is enough to discharge pressure when loine pressure exceedes permissible value, it is to avoid because of the generation of the excessive caused security incident of pressure.
According to the technical scheme that the utility model is provided, spring micro-open type safety valve includes bonnet and valve body, bonnet and valve
Body is bolted integrally, bonnet upper end connection top cover, it is characterized in that：Body cavity is provided with valve seat, valve seat upper end open
Place is provided with flap, and flap upper end connection valve rod, valve rod upper end is slidably connected in adjusting bolt, and adjusting bolt outer surface passes through spiral shell
Line connects bonnet；Pocketed springs on valve rod, spring upper and lower side is respectively equipped with positioning seat and lower positioning seat, and upper positioning seat is fixed on
In adjusting bolt, lower positioning seat is fixed on valve rod；The body base is provided with air inlet, and air inlet connects with valve seat lower ending opening
Logical, valve body side is provided with gas outlet.
Further, protective case is provided between bonnet and adjusting bolt.
Further, the diffusion shell of cone is connected on flap.
Further, it is provided with guide holder between bonnet and valve body, guide holder is slidably connected valve rod.
Compared with the prior art the utility model has advantages below：
It is the utility model simple structure, compact, reasonable, pressure can be discharged when loine pressure exceedes permissible value, it is to avoid
Because of the generation of the excessive caused security incident of pressure；Good seal performance, opens wide pressure breathing, and discharge capacity is big, and time seat pressure difference is small, adjusts
It is whole easy to maintenance.
Brief description of the drawings
Fig. 1 is the utility model front view.
Description of reference numerals：1- bonnets, 2- valve bodies, 3- valve seats, 4- flaps, 5- guide holders, 6- valve rods, 7- springs, 8- are adjusted

Specific embodiment
The utility model will be further described with reference to the embodiment in accompanying drawing below：
As shown in figure 1, the utility model mainly includes bonnet 1 and valve body 2, bonnet 1 and valve body 2 are bolted into one
Body, the upper end of bonnet 1 connection top cover 9.
The inner chamber of valve body 2 is provided with valve seat 3, and flap 4 is provided with the upper end open of valve seat 3.The upper end of flap 4 connects valve rod 6, valve rod 6
Upper end is slidably connected in adjusting bolt 8, and the outer surface of adjusting bolt 8 is connected through a screw thread bonnet 1.
It is provided with guide holder 5 between bonnet 1 and valve body 2, guide holder 5 is slidably connected valve rod 6, motion of the guide holder 5 to valve rod 6
Play guide effect.
Pocketed springs 7 on valve rod 6, the upper and lower side of spring 7 is respectively equipped with positioning seat 11 and lower positioning seat 12, upper positioning seat 11
It is fixed in adjusting bolt 8, lower positioning seat 12 is fixed on valve rod 6.
The diffusion shell 15 of cone is connected on the flap 4, gas passes through diffusion after being flow on flap 4 from valve seat 3
Cover 15 spreads, it is to avoid the direct dash valve body madial wall of pressure of air-flow, improves service life.
Protective case 10 is provided between the bonnet 1 and adjusting bolt 8, protective case 10 avoids adjusting bolt 8 from being sent out on bonnet 1
Raw movement.
The bottom of the valve body 2 is provided with air inlet 13, and air inlet 13 is connected with the lower ending opening of valve seat 3, and the side of valve body 2 is provided with out
Gas port 14.
Operation principle of the present utility model is：The utility model is connected on pipeline, air inlet and pipeline connection.In work
When making, if the pressure of pipe-line system exceedes setting, gas medium pressure overcomes spring force to push flap open, by one in system
The medium for dividing is imported in valve body cavity, then along gas outlet discharge.After pipe-line system pressure is normal, spring pressure drives flap pressure
Tight valve seat, closes release channel.
It is the utility model simple structure, compact, reasonable, pressure can be discharged when loine pressure exceedes permissible value, it is to avoid
Because of the generation of the excessive caused security incident of pressure；Good seal performance, opens wide pressure breathing, and discharge capacity is big, and time seat pressure difference is small, adjusts
It is whole easy to maintenance.
