(flange part)

Figure 10 is by the half section figure in the left side of the periphery enlarged representation of the flange part 54 of the cover body 50 of Fig. 9.In flange part 54 upper surface is provided with:The convex portion 60a of the ring-type swelled upward;And with towards lower recess on the inside of the radial direction of convex portion 60a The recess 60b of ring-type that formed of mode.The abutting part 76 of the ring-type abutted for valve element 80 is provided with the top of the 60a of convex portion.Such as Shown in Fig. 9, the diameter D1 of abutting part 76 is formed as the diameter D2 equal to or more than opening 30.Especially, abutting part 76 is in radius The outer fix of the marginal position or the edge of opening 30 is formed on direction.

Figure 11 is the schematic diagram of the hydraulic pressure that explanation puts on cover body 50.Figure 12 is the cover body 250 that explanation puts on comparative example Hydraulic pressure schematic diagram.Figure 11 and Figure 12 is illustrated centered on the section of the left side half of cover body.The cover body of comparative example is illustrated first 250.The abutting part 276 for being connected to valve element 80 of cover body 250 is formed in the radial direction than the abutting part 76 located at cover body 50 Inside.That is, the abutting part 276 of cover body 250 is in the radial direction positioned at the inner side of opening 30.

When faucet is in closing, the water 300 of the scheduled hydraulic pressure in upstream side (downside) in partition wall portion 20 is full of, partition wall portion 20 downstream is atmospheric pressure state.In this condition, hydraulic pressure is applied to all faces contacted with water 300 of cover body 250. This, if illustrating from above-below direction, applies the area of lower surface portion 272 is multiplied by obtained from hydraulic pressure to lower surface portion 272 Power Fu2 upward.On the other hand, the area under the vertical view of recess 260b is multiplied by hydraulic pressure and is obtained by the recess 260b applyings to upside Power Fd2 directed downwardly for arriving.

Due to the area under the vertical view of recess 260b it is less than the area of lower surface portion 272, so Fd2 is less than Fu2, its result It is that cover body 250 is subject to the poor power between Fu2 and Fd2 upward.If cover body 250 is subject to poor power upward all the time, when in the state When bottom spool 80 somewhat rises and opens, the pressing of upside disappears, and cover body 250 is likely due to differ from power and come off.

As shown in figure 11, in the case of cover body 50, as the area of recess 60b is equal to or more than lower surface portion 72 Area, so power Fd1 directed downwardly is equal to or more than power Fu1 upward.As a result, cover body 50 is hardly subject to upper and lower To power, or be subject to poor power directed downwardly.Thus, the probability that cover body 50 is come off due to hydraulic pressure significantly diminishes.

Then, illustrate the feature of the faucet 100 of present embodiment.

For example, it is not the valve seat member of one that the faucet described in patent documentation 1 is provided with tap main body, but due to The construction of tap main body is special, so the shape of faucet suffers restraints.In this regard, the faucet 100 of present embodiment is cover Body 50 is fitted to the structure of opening 30, few to the shape constraining of faucet, and manufacture labour and time are also few.In addition, using the teaching of the invention it is possible to provide The faucet 100 of excellent corrosion resistance can also be made using cheap material and by using cover body 50 in trunk 102.
