Adopt technique scheme, only need tighten or unscrew hold-doun nut, just can realize the waterexit end of water knockout drum ball valve and being connected and separating of floor heating pipe rapidly, thereby make the I﹠M of valve convenient.In addition, the utility model utilizes the snap action of snap ring and is used seal ring, can guarantee that the joint of valve alive keeps the better fluid sealability.
Description of drawings
Fig. 1 is the cross-sectional view according to the utility model one embodiment's water knockout drum ball valve.
Embodiment
Below in conjunction with accompanying drawing the utility model is made and to be further specified.
As shown in Figure 1, water knockout drum ball valve of the present utility model comprises valve body 1, spool 2, valve rod 3, handle 4, hold-doun nut 5, snap ring 6 and union 7.Valve body 1 has a water inlet interface 11 and a water outlet interface 12, and this water inlet interface 11 is threaded with the person in charge of floor heating water knockout drum, is arranged with seal ring 80 and hexagonal nuts 90 on the outer wall of water inlet interface 11.Spool 2 is arranged in the valve body 1, is provided with a central passage 21 on spool 2.Be respectively equipped with seal ring 81,82 on the valve interior wall of spool 2 both sides.Valve rod 3 rotatably is installed on the valve body 1, and can drive spool 2 rotations.The outer wall of valve rod 3 is provided with several sealed circle 83.Handle 4 is arranged on the top of valve rod 3, and it is connected with valve rod 3 by a screw 91.
The outer wall of water outlet interface 12 is provided with outside thread, and hold-doun nut 5 partly is set on the water outlet interface 12, and is threaded with water outlet interface 12.The profile of hold-doun nut 5 for example can be a hexagon.Snap ring 6 is provided with a longitudinal opening, and cross section is roughly " C " shape.Preferably, on the inwall of snap ring 6, be provided with many annular protrusions 61,, reach better chucking effect to increase frictional force.Snap ring 6 is arranged in the hold-doun nut 5, and is enclosed within the union 7.Union 7 comprises external diameter bigger inlet part 71 and the less outlet part 72 of external diameter, and inlet part 71 forms a ring-shaped step 70 that radially protrudes with the intersection of outlet part 72.Inlet part 71 is inserted in the water outlet interface 12, and snap ring 6 is set on the outlet part 72.The outer wall of inlet part 71 is provided with two annular grooves, is embedded with seal ring 85 respectively in these two annular grooves.The outer wall of outlet part 72 is provided with two annular grooves, is embedded with seal ring 86 respectively in these two annular grooves.The quantity of the annular groove of above-mentioned inlet part 71 and outlet part 72 is not limited to two, also can be one, three etc.
