Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model,
In figure, 1. valve bodies, 2. valve rods, 3. upper covers, 4. butterflys, 5. inlets, 6. liquid outlets, 7. valve hands
Wheel, 8. sealing-plugs, 9. shafts, 10. stop collars, 11. filter screens, 12. glands, 13. mounting bases, 14. connecting rods.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As shown in Figure 1, a kind of multi-functional anti-leakage valve, including valve body 1, valve rod 2, upper cover 3 and butterfly 4,
The left side of the valve body 1 is provided with inlet 5, and the lower end of the valve body 1 is provided with liquid outlet 6, valve body 1
Top be provided with upper cover 3, the valve rod 2 runs through the mounting hole at 3 center of upper cover, is connected with valve handle at the top of the valve rod 2
7, the interconnecting piece of the valve rod 2 and valve handle 7 is provided with ratchet, and being internally provided with for the valve handle 7 is mutual with ratchet
The buckle structure of cooperation, the bottom of the valve rod 2 are connected with sealing-plug 8, and one end of the butterfly 4 is connected with shaft 9, rotation
The other end for turning baffle 4 is provided with protrusion, and the shaft 9 is fixedly connected on valve body 1 close to the inner wall on 5 top of inlet
On, it is provided with the groove matched with protrusion positioned on the inner wall of 5 lower part of inlet, protrusion is matched with groove, structure
Rationally, the effect of limit is not only acted as, while improving the leakproofness of valve, return spring is provided in the shaft 9, works as valve
When bar 2 travels upwardly, return spring drives shaft 9 to rotate, and butterfly 4 moves upwards, and valve is in the open state；Work as valve rod
2 when travelling downwardly, and return spring applies pressure by valve rod 2, and butterfly 4 moves downward, and protrusion engages with groove, plays dual
The effect of blocking solution；Restraining position ring block 10 is set at the liquid outlet 6, and filter screen 11, filter screen is arranged in the upside of the stop collar 10
11 setting can filter out the impurity in liquid, prevent valve blocks, be provided with filler at the valve rod 2 and 3 cooperation of upper cover
