By adopting above-mentioned technological scheme, by traditional, pass through being accessibly connected of Disc holder, flap and valve seat, change to being accessibly connected of direct flap and valve seat, reduced the use of material, meeting working condition requirement simultaneously, reduce cost of production, made the structure of safety valve simpler, compact, and easy for installation.
The technological scheme that the utility model adopts is: described valve gap is provided with the radiating opening for heat radiation.
By adopting above-mentioned technological scheme, improve the heat dispersion of safety valve, guaranteed the stable of interior each parts of valve, especially can avoid the spring of valve gap inside to expand with heat and contract with cold, guarantee that the spring service behaviour is precisely reliable, working efficiency and the working life of having improved spring.
The technological scheme that the utility model adopts is: the cylindrical structure setting of described valve gap, radiating opening ovalize structure arrange, and on described valve gap outer wall, axis is symmetrical is provided with two radiating openings that run through.
By adopting above-mentioned technological scheme, on the valve gap outer wall, axis is symmetrical is provided with two radiating openings that run through, and the heat in valve gap is spread, and has further improved the heat dispersion of safety valve.
The technological scheme that the utility model adopts is: described valve seat has Adjusting ring, flap to be provided with for Adjusting ring, forming the boss part that location coordinates towards the outside cover of valve gap one end, and slipping part, boss part, abutting part one successively connect.
By adopting above-mentioned technological scheme, the unlatching height that the energy regulation safety valve is set of Adjusting ring, release pressure and time seat speed, improve stability, the dependable with function of work.
The technological scheme that the utility model adopts is: the sealing surface of described valve seat is made by Hardmetal materials, and flap is made by the stainless iron material.
By adopting above-mentioned technological scheme, the high hardness of cemented carbide and wear resistance are very good, the life cycle that has extended valve seat; Stainless iron is corrosion-resistant, and long-term use is not fragile, economical and practical.
The beneficial effects of the utility model are: owing to taking technique scheme, flap in safety valve has replaced Disc holder, allow the structure of safety valve become simple, install more compact, reduced the cost of material of producing, and valve gap is provided with the radiating opening for heat radiation, inspection convenience during maintenance, can make heat radiation in time in valve, guarantee stability and the reliability of valve inner piece work.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference character in figure: 1-valve body, 2-valve gap, 3-valve rod, 4-valve seat, 5-upper spring seat, 6-lower spring cup, 7-spring, 8-flap, 9-guide sleeve, 10-radiating opening, 11-Adjusting ring.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in Figure 1, the strap wrenches spring micro-open type safety valve, comprise valve body 1, valve gap 2 and valve rod 3, the other end of the interior corresponding valve gap 2 of described valve body 1 is provided with valve seat 4, valve gap 2 is provided with upper spring seat 5, lower spring cup 6 and being fixedly arranged on, spring 7 between lower spring cup, spring 7 is set on valve rod 3, one end of the corresponding valve seat 4 of described valve rod 3 is connected and can forms the flap 8 be tightly connected with valve seat 4, the outer guide sleeve 9 that is arranged with of flap 8, guide sleeve 9 is fixedly arranged on the joint of valve body 1 and valve gap 2, described flap 8 is provided with can be along the slipping part of guide sleeve slippage Shang Xia 9 and for valve seat 4, forming the abutting part be tightly connected.By traditional, pass through being accessibly connected of Disc holder, flap 8 and valve seat 4, change to being accessibly connected of direct flap 8 and valve seat 4, reduced the use of equipment and materials, reduced production cost, make the structure of safety valve compacter, and easy for installation.
