This practicality only needs to control rotatoryly with the knob, drive the valve rod up-and-down motion can, can not only carry out coarse adjustment, can also adjust slightly, satisfied the different foams that require of washing thing of difference.
As a further improvement and supplement to the above solution, the present invention further comprises the following additional technical features:
the gasket be the sawtooth gasket, and the material is 65Mn, can effectively carry out locking, 65Mn comprehensive properties is good.
The valve rod is connected with the knob through the square block, so that the connection is convenient, and the sliding cannot occur during rotation.
The valve rod is provided with a cone below the thread, so that the channel can be closed.
The valve rod is provided with a first O-shaped ring and a second O-shaped ring, so that the sealing in the use process and the sealing in the non-use process are ensured.
The valve body and the valve rod are made of copper, so that the valve body and the valve rod are good in corrosion resistance and long in service life.
The knob is provided with bulges in the circumferential direction, so that the knob cannot slip when being rotated.
Use the utility model discloses following beneficial effect can be reached: the utility model has the advantages of reasonable structure, adjust the convenience, as long as control to twist the knob, drive the valve body up-and-down motion can, because thin threaded connection can not only carry out the coarse adjustment, can also carry out slight adjustment, adjust effectually, the foam is according to the difference of wasing the thing, transfers best user state. The first O-shaped ring is arranged to ensure the sealing performance of the regulating valve in the using process, the leakage phenomenon cannot occur, and the second O-shaped ring is arranged to completely seal the connecting channel under the condition that foam is not needed to be used, so that the valve rod and the valve body are protected.

Fig. 2 is a front view of the present invention.
Fig. 3 is a schematic structural diagram of the middle valve rod 2 of the present invention.
Detailed Description
The following detailed description of embodiments of the present invention will be made with reference to the accompanying drawings.
As shown in figures 1-3, the utility model relates to a regulating valve which can conveniently regulate the dryness and the humidity of foam.
The regulating valve convenient for regulating the dryness, the wetness and the size of foam comprises a valve body 1, wherein the valve body 1 is a transverse two-port structure and a longitudinal one-port structure, a channel is of an upward inclined structure at an inlet end and is communicated with an inner cavity of the longitudinal port, and the channel is of an upward inclined structure at the bottom of the longitudinal port at an outlet end. The valve body 1 is internally threaded with a valve rod 2, and the valve body 1 and the valve rod 2 are connected by fine threads to adjust the upper position and the lower position of the valve rod 2; the outside of the valve rod 2 is provided with a fixing nut 3 in threaded connection with the valve body 1, the valve body 1 is connected with the fixing nut 3 through a pipe thread structure, the strength is good, the valve rod 2 moves upwards to be limited, and the valve rod 2 moves up and down according to the requirement of the distance as required, and the position of the fixing nut 3 and the valve body 1 can be adjusted up and down. The valve rod 2 penetrates through the fixing nut 3 and is fixedly connected with the knob 4 through a screw, and a gasket 5 is arranged between the screw and the knob 4.
Further, the pad 5 is a sawtooth pad, and the material is 65Mn, and the sawtooth pad can be a kind of prior art, and is not shown in the figure.
Furthermore, the valve rod 2 is connected with the knob 4 by a block 21.
Furthermore, a cone 22 is arranged below the thread of the valve rod 2, a large oblique transition hole and a small oblique transition hole are arranged in the cavity of the longitudinal joint, and the cone 22 can be attached to the oblique transition holes downwards to seal the inlet and outlet channels.
