The embodiments described below are exemplary and are intended to be illustrative of the present invention, but should not be construed as limiting the invention.

Example 1.

As shown in fig. 1, a reset valve cartridge is characterized by comprising: the valve comprises a valve seat 1 with a valve cavity, a push rod 9 and a reset button 3 which are connected with the valve seat 1 in a sliding way, and a spring 8 which is arranged between the valve cavity and the push rod 9 and is used for resetting the push rod 9; the push rod 9 and the reset button 3 are arranged oppositely, a second magnet 7 is arranged at one end, close to the reset button 3, of the push rod 9, a first magnet 4 is arranged at one end, close to the push rod 9, of the reset button 2, the first magnet 4 and the second magnet 7 repel each other, and the push rod 9 is matched with the one-way valve and used for pushing a valve core of the one-way valve.

Like this, when the in-service use, the user presses reset button, and reset button drives magnet downstream makes the push rod also downstream under the effect of magnet to open the case of check valve because of the mutual repulsion effort between the magnet, when loosening reset button, and push rod and second magnet upward movement under the effect of spring, first magnet upward movement drive reset button under the repulsion force effect of second magnet resets. When the problems that sand particles are stuck, scaling adhesion cannot open the valve and the like occur in the one-way valve, the reset button of the reset valve core is pressed for several times outside the connecting valve, and then the sand particles can fall off and the one-way valve can be opened again.

Specifically, the push rod 9 and the second magnet 7 are connected through a second fixing nail 6; the reset button 3 and the first magnet 4 are connected through a first fixing nail 5. The first fixing nail, the second fixing nail, the push rod and the reset button can be made of plastic materials, and scaling is not prone to occurring. The connection mode between the second fixing nail and the push rod and between the first fixing nail and the reset button is not limited, and the second fixing nail and the push rod can be in threaded connection, can also be in ultrasonic welding, and can even be bonded by 502 glue. In this embodiment, it is preferable that threaded holes are formed at the end portions of the push rod 9 and the reset button, the first fixing nail is connected with the reset button through a thread, and the second fixing nail is connected with the push rod through a thread. Thus, the magnet is convenient to disassemble and replace.

Further, the top of the valve seat 1 is provided with a first blocking cover 2, and the first blocking cover 2 is provided with a first installation through groove for allowing the reset button 3 to penetrate out. And a limiting convex edge matched with the first installation through groove is arranged on the side wall of the reset button 3.

The bottom of disk seat 1 is equipped with second blanking cover 10, be equipped with on the second blanking cover 10 and hold the second installation that the push rod was worn out leads to the groove be equipped with on the second installation leads to the groove and is used for the installation the mounting groove of spring 8 be equipped with on the push rod 9 with the protruding edge of top complex installation of spring.

The first blocking cover 2 and the second blocking cover 10 are detachably connected with the valve seat 1, in this embodiment, the first blocking cover 2 and the second blocking cover 10 are connected with the valve seat 1 through threads, and it is obvious that a person skilled in the art can adopt other connection modes such as clamping and the like according to actual use conditions. Therefore, the blocking cover can be conveniently opened to maintain and replace the parts in the valve core.

It should be noted that, a first valve cavity for installing the first magnet and the reset button and a second valve cavity for installing the second magnet, the spring and the push rod are arranged in the valve seat. A partition plate is arranged between the first valve cavity and the second valve cavity. The inside advantage that adopts magnet and baffle of case that resets lies in the static seal, and the reset button is inside to have the pressure water route, if directly adopts the push rod, then need use the sealing washer to do the movive seal on the push rod, so will lead to the push rod motion dumb, and sealing reliability is low, and the scale deposit scheduling problem appears in push rod cooperation position even, adopts magnet interact, then can compromise the flexibility of sealed effect and promotion.

In this embodiment, the diaphragm and the valve seat are a unitary member. The disk seat is the brass material, the baffle is the partly of brass disk seat, and this disk seat both ends are drawn empty promptly and are done the cavity that holds magnet, and the interlayer of certain thickness is remained to the centre, about 1mm, only need water pressure resistant can, the structure leakproofness of this integral type is more reliable, and the thin copper baffle is minimum to the decay effect in magnetic field, can neglect.

Example 2.

As shown in fig. 2, a connecting valve includes a valve body 300 and a check valve 200 provided in the valve body 300; the reset valve core 100 matched with the one-way valve is characterized in that the valve body 300 is provided with the reset valve core 100 matched with the one-way valve in the embodiment 1.

Specifically, in this embodiment, a hot water inlet 301, a cold water inlet 303, a hot water outlet 302, and a cold water outlet 304 are disposed on the valve body; the check valve 200 is disposed between the hot water inlet 301 and the cold water outlet 304 and the cold water inlet 303.

The valve body 300 is provided with an installation opening opposite to the valve core of the one-way valve 200, the reset valve core 100 is installed on the installation opening through threads, and the valve core of the one-way valve can be jacked open by the downward movement of the push rod of the reset valve core. And a sealing ring 11 is arranged between the mounting opening and the reset valve core, so that the sealing effect is ensured.

The connecting valve provided by the embodiment has all the advantages of the embodiment 1, and the description is omitted.
