Description

Precision ceramic flow channel switching valve

technical field

The utility model relates to a switch valve, in particular to a precision ceramic flow channel switch valve applied to sanitary equipment.

Background technique

Press, most of the current common bathroom equipments are designed with two kinds of water outlet methods, one is to use the water flow directly from the faucet to accommodate the bathtub and water basin, and the other is to connect the water pipe to the shower head to provide water from a high place. In the shower, when the two different water outlet methods are used on the same faucet, a pull rod is used to control the rotation of the control valve arranged in the faucet, so that the water outlet can be switched.

However, at present, handle-type control valves are commonly used. When switching the water flow direction, the control valve is used to achieve water flow from the first water outlet or the second water outlet, and the control valve uses a pull rod to cooperate with an elastic member to achieve cutting control. state, it is easy to cause the fatigue of the elastic part due to long-term cutting control, and then it cannot effectively achieve the state of cutting control and water stop, and after the control valve is actuated by the pull rod pull, the pressure of the water flow makes the pull rod limit the position, when the user When the water source is turned off and the water flow pressure is lost inside the faucet, the pull rod will be reset by the elastic member, so that when the water is used next time, the pull rod pull of the cutting control device must be activated again to achieve the previous cut. It is inconvenient to use the structure to control the state of the water, and it does not have the accuracy of cutting and controlling the water flow, and lacks practicability.

In view of this, the applicant of the present utility model has been engaged in the manufacture, development and design of related products for many years. After detailed design and careful evaluation for the above-mentioned goals, he finally obtained a practical utility model.

The second water outlet 52 communicates, so that when the mixed water flows into the accommodating space 11 from the water inlet 16, it will flow out from the second water outlet 52 to reach the state of shower head water outlet, and the water output of the shower head is also equal to that of the control valve rod 20 and the water outlet of the shower head. The displacement of the interlocking valve seat 30, and when the flow opening 42 and the second water outlet 52 form a fully open water outlet state, the abutment rib 33 of the interlocking valve seat 30 abuts against the other side of the arc-shaped retaining wall 111 One side forms a positioning (as shown in FIG. 10 ), thereby limiting the rotation range of the control valve rod 20 .

To sum up, when the user wants to close the water flow, the control valve stem 20 is rotated to the center again, so that the positioning rib 34 of the interlocking valve seat 30 rebounds using the elastic gap 341, and then inserts into the valve housing 10 The internal positioning groove 121 forms a positioning state (as shown in FIG. 6 ), which indirectly allows the user to feel the switch feel of the engaged positioning, and then allows the user to know that the water has been turned off.

And the cylinder 31 of the interlocking valve seat 30 is covered with a water-stop gasket 312 by the ring groove 311, and is closely attached to the inner wall of the limiting container 13, so that when the mixed water enters the containing space 11 from the water inlet 16, its water flow That is to say, the water-stop gasket 312 stops the outside of the limiting tank 13, which not only prevents the water flow from seeping through the hole 14 of the valve casing 10, but also prevents the water flow from contacting the control valve stem 20 to pollute the water source. , metamorphism.

By the structure of above-mentioned specific embodiment, can obtain following benefit:

1) The inside of the switching valve of the present utility model uses a precision ceramic sheet to control the opening and closing, so that the switching of the water flow can be more accurate, and the valve housing 10 and the linkage valve seat 30 are also provided with a positioning groove 121 And the positioning rib 34 allows the user to know the switching state of the water flow through the cutting control feeling produced by the positioning rib 34 embedded in the positioning groove 121 during the cutting control process, which is practical.

2) Between the interlocking valve seat 30 and the valve housing 10, there is also a supporting rib 33 and an arc-shaped retaining wall 111. When the user switches between the water flow of the faucet and the shower head, the first water outlet 51 or the second When the water outlet 52 and the flow opening 42 are fully opened, the abutment rib 33 of the interlocking valve seat 30 will abut against the arc-shaped retaining wall 111 to form a limit, which not only allows the user to know exactly The current state of the boiling water flow, on the other hand, can also limit the control range of the control valve stem 20 and the interlocking valve seat 30, increasing the accuracy of water flow control.
