Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a valve-

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a valve replacement apparatus, and more particularly, to an end water valve replacement apparatus for easily replacing a valve without leakage of fluid.

Generally, a water supply pipe is composed of a main pipe of large diameter for transferring a large capacity constant at a long distance and a branch pipe for branching at a main pipe and used for relatively short distance transportation (supply of water to houses and offices). A valve is provided at the branch where the branch pipe branches from the main pipe, so that the constant transferred to the branch pipe is controlled.

If the valve is used for a long period of time, it must be replaced and replaced even if it is damaged or broken.

When replacing a valve, the work usually takes place after all the valves connected to the periphery are locked because of leakage concerns. Therefore, not only the area where the water is supplied through the valve but also the other areas in the vicinity also have a problem that the residents are inconvenienced.

In order to solve such a problem, there has been developed and used an end-effector valve replacement apparatus which can replace the valve without closing the valve connected to the periphery when the valve is replaced, for example, Korean Patent Publication No. 2012-0046364 (Hereinafter referred to as 'Prior Art Document 1'), Korean Patent Publication No. 0897366 (hereinafter referred to as 'Prior Art Document 2') and Korean Patent Publication No. 1001130 (hereinafter referred to as 'Prior Art Document 3') .

In the case of the prior art document 1, after the wiping valve to be replaced is opened and the top rubber plug is advanced through the spindle to seal the branch hole of the main pipe, additional operations are performed to prevent the spindle from being pushed by the water pressure . Prior art 1, which has undergone such a process, has the advantage of being able to replace the valve without a single valve, but the valve replacement operation is complicated.

In the case of the prior art document 2, an auxiliary pipe is additionally connected to the main pipe in addition to the main pipe to which the valve is mounted. When the valve is to be replaced, the main pipe with the valve attached thereto is released, After replacing the valve, the auxiliary pipe is disconnected and the main pipe is reconnected. In the case of the prior art document 2 which is subjected to such a work process, the auxiliary pipe needs to be separately provided, so that the installation cost is high and leakage is generated during the pipe separation and connection process.

In the case of the prior art document 3, the fixing member is passed through the valve to be replaced, and then the fixing member is fixed to the inside of the water pipe to which the valve is connected. The blocking member is also inserted into the water pipe through the valve together with the fixing member. The water pressure of the water supply pipe is used to seal the inside of the water supply pipe. In the case of the prior art document 3 which is subjected to such a work process, since the blocking member is operated by the water pressure of the water pipe, there is a possibility that the sealed state is not uniform in the case of hydraulic pressure change,

Korean Patent Publication No. 2012-0046364 (2012.05.10. Disclosed) Korean Registered Patent No. 0897366 (published on May 15, 2009) Korean Patent Publication No. 1001130 (published on Dec. 14, 2010)
