Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a water-stopping core which is convenient for pipeline maintenance and a water valve with the water-stopping core. Background Art

[0002] Faucet is a popular name for water valve, which is used to control the size of water flow and has the effect of saving water. The replacement speed of faucets is very fast, from the old cast iron process to the electroplated knob type, and then to the stainless steel single temperature single control faucet, stainless steel double temperature double control faucet, and kitchen semi-automatic faucet. Now, more and more consumers will consider the material, function, shape and other aspects when purchasing faucets.

[0003] Water valves are widely used and are used in showers, kitchens, balconies and other places. Usually, water valves are installed during the construction of the house. According to customer needs, an installation port for the water outlet is reserved on the wall or pipe at a designated location to facilitate subsequent installation of an angle valve or faucet by the customer on the water outlet. When the customer does not install the water valve at the water outlet for use, a sealing plug needs to be installed on the water outlet to prevent water from continuously gushing out after the sluice gate is opened, causing water accumulation indoors or outdoors. During the installation of the water valve, the sluice gate needs to be closed before installation.

[0004] After the water valve is installed on the reserved water outlet, if the water valve needs to be disassembled, in order to prevent water from continuously gushing out, the water gate needs to be closed first, and then the faucet can be removed from the water outlet. After the water valve is reinstalled, the water gate needs to be opened again. The water valve cannot be disassembled without closing the water gate, and the convenience of disassembly and maintenance of the water valve cannot be improved. The disassembly process is relatively complicated. Utility Model Content

[0013] A further improvement is that the driving member is a compression spring arranged between the moving rod and the water inlet pipe, which is used to abut against the other end of the moving rod and the water inlet pipe respectively after the water outlet seat is connected to the water inlet pipe, and push the moving rod to drive the valve disc away from the valve seat end, and one end of the compression spring abuts against the valve core mounting seat on the water inlet pipe.

[0014] A further improvement is that two protective gaskets are provided at both ends of the compression spring to prevent the compression spring from wearing the other end of the moving rod and the water inlet pipe when the compression spring abuts against the other end of the moving rod and the water inlet pipe respectively, and the two protective gaskets are provided with through holes for water to flow through.

[0017] A further improvement is that a sealing ring is located between the valve flap and the valve seat in the connecting pipe and is used to improve the sealing performance between the valve flap and the valve seat when the valve flap closes the water outlet.

[0018] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: after the water valve is installed on the reserved water outlet end, if the water valve needs to be disassembled, it is only necessary to directly remove the water inlet pipe on the water valve from the water outlet seat. When the water outlet seat is not connected to the external water inlet pipe, the valve disc is impacted by the water flow from the external water outlet end and moves closer to the valve seat end, so as to abut against the valve seat to close the water outlet hole and prevent water from continuously gushing out of the water outlet hole. When a new water valve is installed on the water outlet seat, after the water outlet seat is connected to the external water inlet pipe, the moving rod is pushed by the compression spring to drive the valve disc away from the valve seat end to open the water outlet hole, and the water flow from the water outlet end continuously flows toward the water outlet seat through the water outlet hole, thereby allowing the water flow to flow into the water valve. The water valve can be disassembled without closing the sluice gate, which can improve the convenience of disassembly and maintenance of the water valve, and the disassembly process is relatively simple.

[0019] Further effect: when the water valve is installed on the water outlet seat and the water inlet pipe of the water valve is broken, the moving rod loses the push of the compression spring, so that the valve disc is impacted by the water flow and moves closer to the valve seat end, so as to press against the valve seat to close the water outlet hole, thereby preventing water from continuously gushing out when the water inlet pipe is broken.

[0020] Further effect: the compression spring can gradually flexibly push against the moving rod and gradually increase the elastic potential energy when the water outlet seat is connected to the external water inlet pipe, thereby gradually increasing the driving force on the moving rod.

DETAILED DESCRIPTION

[0031] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments. Example

[0032] See also Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 As shown, the technical solution adopted in this specific embodiment is: a water-stop core that is convenient for pipeline maintenance, including a connecting pipe 1 for connecting to an external water outlet, a water outlet seat 2 arranged on the connecting pipe 1 for connecting to an external water inlet pipe, a valve seat 3 arranged between the connecting pipe 1 and the water outlet seat 2, a water outlet hole 4 opened on the valve seat 3 for water to flow through the valve seat 3, and also includes a movably arranged on the valve seat 3 and located in the water outlet hole 4 for being impacted by the water flow from the external water outlet end to the valve seat 3 when the water outlet seat 2 is not connected to the external water inlet pipe.

When the connecting pipe 1 is connected to the water outlet seat 2, the two limit plates 20 gradually push the moving rod 6 to drive the valve disc 5 to open the water outlet 4. Or it can be an elastic bellows or elastic sheet. The spring force of the compression spring 7 is the force that can push the moving rod 6 to drive the valve disc 5 away from the end of the valve seat 3 after the water outlet seat 2 is connected to the water inlet pipe 16. The spring force generated after the spring contracts is greater than the driving force of the water flow.
