Abstract
The invention relates to a bleeding valve realizing a sealing effect by adopting magnetic force and the gravity of a valve cap. The bleeding valve comprises a counterweight, a lever, a rotating shaft, a valve body, a valve cap, a seal ring, a sealing valve seat, an outer compression ring for the seal ring, and an inner compression ring for the seal ring, and is characterized by further comprising a permanent magnet which is fixed on the valve body and used for attracting the valve cap. The bleeding valve has the benefits that as the attractive force of the magnet is adopted on the condition that the opening pressure of the bleeding valve is balanced and the sealing is guaranteed, the weight of the valve cap is greatly reduced, and impact as well as the vibration of a pipeline generated during the opening and the closing of the valve cap is reduced. Therefore, threats to a system are reduced.
Description
Technical field
The present invention relates to a kind of valve that diffuses that utilizes magnetic force and valve gap gravity to realize sealing.
Background technique
Diffusing valve is a pressurize, pressure relief device, is used in systems such as blast furnace, treatment of urban garbage more, and traditional valve that diffuses comprises counterweight, lever, running shaft, valve body, valve gap, seal ring, seal valve seat, seal ring outer press ring and seal ring inner pressure ring etc.Its working procedure is following: when pipeline pressure raises suddenly, diffuse valve and become open mode by closed condition, outwards discharge gas; Pressure is reduced, be not damaged with the protection whole system, when pipeline pressure is reduced to desired level; Diffuse valve and close automatically, guarantee the proper functioning of system.Because the cracking pressure of diffusing valve is come balance by counterweight, valve gap, when cracking pressure is higher; Valve gap need be done heavyly especially; This has just caused valve opening, when closing, the strength of impact is big especially, so loss of weight, impact-reducing have just become this type of to diffuse the valve problem demanding prompt solution.
Diffusing valve groundwork principle is: valve gap passes through to realize with the effect of seal ring the sealing of pipeline gas, and when the pressure of gas in the pipeline reached setting value, gas overcame the gravity that valve gap produces through the effect to valve gap; Valve gap is opened, realized that pipeline gas discharges, and reduces pipeline pressure; When pressure drops to setting value; Valve gap is landing automatically under action of gravity, and through the sealing of crush seal circle, blocks the gas that leaks; Whole system is stabilized on the pressure of setting, through the position and the fine-tuning switch pressure of weight of adjustment counterweight.
Above-mentioned shortcoming of diffusing valve is because the pressure ratio that pipeline is set is higher, diffuse that the valve gap of valve need do especially greatly, heavy especially, valve opening, when closing, the vibration of generation is big especially, and whole tubing is constituted a threat to.
Summary of the invention
Technical problem to be solved by this invention provides a kind of valve that diffuses that utilizes magnetic force and valve gap gravity to realize sealing.
The present invention solve its technical problem the technological scheme that will adopt:
The present invention includes counterweight, lever, running shaft, valve body, valve gap, seal ring, seal valve seat, seal ring outer press ring and seal ring inner pressure ring; It is characterized in that also comprising the permanent magnet of the attraction valve gap that is fixed on the said valve body.
Said permanent magnet is an annular permanent magnnet, and said annular permanent magnnet is bolted on the said valve body through retainer ring, holding down bolt and adjustment; Said retainer ring is welded on the upper end portion of outer side of valve body; On said retainer ring, be evenly equipped with the bolt hole of installing and locating bolt; The positioning bolt hole outside on said retainer ring is evenly equipped with the through hole that said adjustment bolt is installed, and on said annular permanent magnnet, is evenly equipped with the through hole that said adjustment bolt is installed.
The invention has the beneficial effects as follows owing to introduced magnetic pull with guaranteeing to seal in the compensation flap cracking pressure; Reduced the weight of valve gap greatly; Reduced valve gap impact force in the opening and closing process, to Analysis of Pipe Vibrations, reduced threat when having reduced keying system.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Fig. 3 is the I place partial enlarged drawing of Fig. 1.
In Fig. 1-3,1 counterweight, 2 levers, 3 running shafts, 4 valve bodies, 5 valve gaps, 6 seal rings, 7 holding down bolts, 8 retainer rings, 9 adjustment bolts, 10 annular permanent magnnets, 11 seal valve seats, 12 seal ring outer press rings, 13 seal ring inner pressure rings.
Embodiment
Embodiment 1:
Said permanent magnet is an annular permanent magnnet 10, and said annular permanent magnnet 10 is fixed on the said valve body 4 through retainer ring 8, holding down bolt 7 and adjustment bolt 9; Said retainer ring 8 is welded on the upper end portion of the outer side wall of valve body 4; On said retainer ring 8, be evenly equipped with the bolt hole of installing and locating bolt 7; The positioning bolt hole outside on said retainer ring 8 is evenly equipped with the through hole that said adjustment bolt 9 is installed, and on said annular permanent magnnet 10, is evenly equipped with the through hole that said adjustment bolt 9 is installed.
When system pressure raise suddenly, pressed gas impacted valve gap 5, when gas percussion power during greater than the attraction force of valve gap 5 gravity and annular permanent magnnet 10; Said seal valve seat 11 is along with the rotation of valve gap 5 is separated from seal ring 6, and valve outwards discharges gas, and system pressure is reduced; Be not damaged with the protection whole system, when system pressure was reduced to desired level, said valve gap 5 fell under the self gravitation effect automatically; Under valve gap 5 gravity and annular permanent magnnet 10 attraction force acts; Seal valve seat 11 on the valve gap 5 is pressed on the seal ring 6, guarantees valve seal, makes system's proper functioning.Said cracking pressure of diffusing valve is come balance by valve gap 5 gravity and annular permanent magnnet 10 attraction forces, and the sealing force of valve gap 5 is guaranteed by the attraction force of valve gap 5 gravity and 10 pairs of valve gaps 5 of annular permanent magnnet.
As shown in Figure 3, through adjustment holding down bolt 7 and adjustment bolt 9, the gap that can regulate annular permanent magnnet 10 and valve gap are 5 with the different attraction forces of realization annular permanent magnnet 10 with 5 of valve gaps, reaches different switch pressure.
The present invention is applicable to blast furnace system, the pressurize of treatment of urban garbage system, pressure relief device, and the protection whole system is not damaged.
