Examples

As shown in fig. 1-2, a novel PSP pipe large-flux connecting valve comprises a valve body, a valve rod 1, a valve plate 2 and a hand wheel 3, wherein the PSP pipe is connected with the valve body, and a plastic shell 4 is arranged outside the valve body.

The valve body is divided into an upper valve body 5 connected with the valve rod 1 and a lower valve body 6 containing the valve plate 2, and the upper valve body 5 and the lower valve body 6 are integrally formed. Go up 5 internal thread connections of valve body and have valve rod 1, hand wheel 3 is installed through the nut in the top of valve rod 1, and valve plate 2 is installed to the bottom of valve rod 1, and valve plate 2 agrees with the opening of the bottom of lower valve body 6, and it is placed in the opening promptly. And a sealing filler is arranged in the upper valve body 5 to ensure the sealing property of the whole valve body.

Specifically, the hand wheel 3 is rotated to adjust the rising and falling of the valve rod 1, i.e. the valve rod 1 can perform the rising and falling actions relative to the upper valve body, so that the closing and opening and closing of the valve plate 2 and the bottom of the lower valve body 6 can be controlled by the rising or falling of the valve rod 1, i.e. after the valve rod 1 is lowered in the upper valve body 5 by rotating the hand wheel 3, the valve plate 2 at the bottom is positioned in the opening of the lower valve body 6, which can close the whole valve body, i.e. prevent the medium in the externally connected PSP pipe from flowing; when the hand wheel 3 rotates to drive the valve rod 1 to ascend in the upper valve body 5, the valve plate 2 at the bottom of the valve rod 1 is separated from the lower valve plate 2, and after the lower valve body 6 is not blocked by the valve plate 2, the lower valve body is in a through state, namely, a medium in the PSP pipe can flow through the valve body. And the valve body is a quick-wear tool and needs to be maintained frequently, and the sealing filler is arranged in the upper valve body 5, so that the medium leakage can be prevented. By adopting the valve body, the joint of the PSP pipe and the valve body is a medium circulation path, the flux of the whole valve body is improved, and the condition that the pressure cannot be smoothly pressurized when the water pressure needs to be improved and the small-flux valve body is upwards circulated in use is avoided.

Further, for the convenience of the use of whole valve body, the utility model discloses still be equipped with fixing device, fixing device is used for avoiding the unexpected proper motion of hand wheel 3 to rotate, influences the work of whole connecting valve. The fixing device comprises a transverse screw 7 and a threaded through hole 8 matched with the transverse screw. The threaded through holes 8 comprise two groups, one group is positioned on the outer wall of the upper valve body 5, and the other group is positioned on the valve rod 1. The positions of the two groups of threaded holes are matched. Wherein, the screw thread through-hole 8 that is located the valve body outer wall has two, and its bilateral symmetry's setting is on the outer wall of valve body, and the screw thread through-hole 8 that is located valve rod 1 has two, and its bilateral symmetry sets up at valve rod 1 outer wall. The screw rod 7 is in threaded connection with the inside of the threaded through hole 8, namely the screw rod 7 penetrates through the threaded through hole 8 on one side of the valve body and then sequentially penetrates through the threaded through holes 8 on the left side and the right side of the valve rod 1 and finally penetrates out of the threaded through hole 8 on the other side of the valve body, so that the valve rod 1 and the valve body are fixed relatively. When the hand wheel 3 does not need to be twisted, the valve rod 1 cannot rotate relative to the upper valve body 5 due to the screw 7, so that the influence on the flow of a medium in the PSP pipe caused by the accidental rotation of the hand wheel 3 due to external influence can be avoided. And when the hand wheel 3 rotates, an operator takes off the screw rod 7 firstly, rotates the hand wheel 3, so that the valve rod 1 can move up and down relative to the upper valve body 5, and after the hand wheel 3 is screwed to the position where the hand wheel cannot be screwed, the thread through hole 8 on the valve body and the thread through hole 8 on the valve body are still corresponding, and then the thread is inserted into the thread through hole 8, so that the valve rod 1 can be fixed, and the stability of the valve body is improved.

Parts not described in the above modes can be realized by adopting or referring to the prior art.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
