Description
Technical field
The present invention relates to a kind of valve, fill with on formula freight container the valve used, particularly relate to a kind of valve filling with use on formula freight container.
Background technology
At present, the bottom valve of prior art, its shortcoming is valve many employings welded construction, it is easy to produce valve body deformation fracture, and valve body does not arrange weak section yet, can not ensure because of accident cause valve to damage time, its sealed structure is still intact, and need to keep manual operation when opening flap, cannot self-locking, operation inconvenience, waste cost of labor.
Summary of the invention
In order to overcome the existing above-mentioned shortcoming blocking bottom valve, the present invention provide a kind of liquid hazardous goods accumulating equipment safety block bottom valve, self-locking can be formed during unlatching, and when anything crops up thus time can effectively protect sealed structure, keep its excellent sealing effect.
The technical solution adopted for the present invention to solve the technical problems is that liquid hazardous goods accumulating equipment safety blocks bottom valve, comprise valve body, valve rod, flap, spring, spring support, valve rod stretches into valve inner, valve rod is positioned at valve body Outboard Sections and connects a spanner, valve rod is positioned at valve inner part and connects a crank, crank connects a bracing frame, bracing frame is provided with postive stop baffle, the end face being connected with tank body on valve body is flange arrangement, end face of flange is evenly distributed three legs, flap is between three legs, three legs are connected with the leg support of spring support, spring fitting is in the middle of spring support and is applied on flap bar, flap bar is through in spring support, flap and valve seat form sealing pair, flap sealing place arranges circular arc ring groove, O is set in arc-shaped slot, crank is provided with spacing end face, the position, flange rear end being connected with tank body outside valve body is provided with breaking groove.
O is made up of the caoutchouc elasticity of FEP polymer overmold.
Valve body adopts integral casting forming.
Circumferential separation groove adopts casting.
The useful effect of the present invention is as follows:
1, the breaking groove of casting is set up at the position, flange rear end being connected with tank body outside valve body, when accident occurs, from breaking groove fracture, valve body is made to be separated into two portions, effectively ensure that valve body and the integrity of tank body connected component bottom valve sealed structure, ensure good sealing effect.
2, crank is provided with spacing end face, is contacted with bracing frame by the place-limited edge limit of spacing end face, is formed effectively spacing when valve wide open, and structure is simple, and without the need to manual operation after standard-sized sheet, medium still can continue discharge.
3, valve body adopts monoblock type casting, improves the shortcoming that welding valve body is easily out of shape fracture, and reduces production cost.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the front view of the present embodiment, is sectional view;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 1,2, in: 1. valve body; 2. crank; 3. flange; 4. circular arc ring groove; 5. flap; 6. spring; 7. flap bar; 8. spring support; 9. flange leg; 10. breaking groove; 11. postive stop baffles; 12. bracing frames; 13. spacing end faces; 14. spanners; 15. valve rods.
Embodiment
As shown in Figure 1, 2, liquid hazardous goods accumulating equipment safety blocks bottom valve, comprise valve body 1, valve rod 15, flap 5, spring 6, spring support 8, valve body 1 adopts integral casting forming, it is inner that valve rod 15 stretches into valve body 1, valve rod 15 is positioned at valve body 1 Outboard Sections and connects a spanner 14, valve rod 15 is positioned at valve body 1 internal portion and connects a crank 2, crank 2 connects a bracing frame 12, bracing frame 12 is provided with postive stop baffle 11, space between postive stop baffle 11 and valve body 1 realizes spacing, ensure that bracing frame is in work area all the time in valve opening and closing process; Between spanner 14 and valve rod 15, between valve rod 15 and crank 2, all adopt involute spline to connect, between crank 2 and bracing frame 12, adopt rivetstructure, ensure the validity of transmission after using for a long time; The end face being connected with tank body on valve body 1 is flange 3, flange 3 end face is evenly distributed three flange legs 9, flap 5 is between three flange legs 9, three flange legs 9 are connected with the leg support of spring support 8, and spring 6 is installed in the middle of spring support 8 and is applied on flap bar 7, and flap bar 7 is through in spring support 8, flap 5 forms sealing pair with valve seat, flap 5 sealing place arranges circular arc ring groove 4, arranges O in arc-shaped slot 4, and O is made up of the caoutchouc elasticity of FEP polymer overmold; Crank 2 is provided with spacing end face 13, and the rib limit on spacing end face 13 contacts with bracing frame 12, it is achieved spacing under standard-sized sheet state of valve, and structure is simple, and without the need to manual operation after standard-sized sheet, medium still can continue discharge; The position, flange 3 rear end being connected with tank body outside valve body 1 is provided with breaking groove 10, breaking groove 10 adopts casting, when accident occurs, rupture from breaking groove 10, valve body is made to be separated into two portions, effectively ensure that the integrity of valve body 1 with tank body connected component bottom valve sealed structure, ensure good sealing effect.
During work, spanner 14 rotates, transmission valve rod 15 rotates, and drives the rotation of crank 2 and bracing frame 12 so that bracing frame 12 withstands flap 5 and moves to tank interior, extrusion spring 6 simultaneously, thus Open valve, when valve is in standard-sized sheet state, the rib limit on spacing end face 13 on crank 2 contacts with bracing frame 12 and forms spacing structure, without the need to manual operation after guarantee standard-sized sheet, medium still can continue discharge; When spanner 14 opposite direction rotates, under the effect of spring 6, it may be achieved valve quick closedown.
