Floating type water nozzle

Abstract

The invention provides a floating type water nozzle which comprises a valve body, a valve rod, a valve core assembly, a valve cover and a hand shank cover, wherein the valve body comprises a water inlet, a water outlet and a valve cavity; a switch control port is formed at the bottom of the valve cavity; the valve core assembly comprises a floating plug; the floating plug is arranged at the bottom of the valve cavity in the valve body and is in clearance fit with the valve cavity; a central blind hole is formed on the upper part of the floating plug and is coaxial with the valve rod; a conical lower sealing pad is arranged on the lower part of the floating plug and corresponds to the switch control port on the lower part of the valve cavity; the valve cover is in threaded connection to anupper opening of the valve cavity; a sealing concave pit is formed on the lower part of the valve cover; a threaded guide slot is formed on the outer cylinder on the upper part of the valve cover; the upper end of the valve rod is fixed on the top of the hand shank cover; the middle part of the valve rod passes through a central hole of the valve cover; the conical end on the lower part of the valve rod is aligned with the central blind hole on the upper part of the floating plug; a disk is arranged on the lower part of the valve rod; a conical upper sealing pad is arranged on the disk and corresponds to the sealing concave pit on the lower part of the valve cover; and a convex column in the inner cavity of the hand shank cover and the threaded guide slot on the outer cylinder on the upper part of the valve cover form an execution mechanism.

Description

technical field [0001] The invention relates to a floating faucet, which is an energy-saving, safe and clean faucet used for the opening and closing of pipeline medium terminals, and belongs to the technical field of pipeline valves. It is mainly used in the daily water supply business, which can effectively solve the problem of poor sealing performance of the traditional cold water nozzle. Background technique [0002] The cold water spout is derived from the pipeline valve (commonly known as "faucet"). There are many styles at home and abroad, but in terms of internal opening and closing structure and sealing form, there are currently only two types. Spiral lifting faucet", one is the "ceramic sheet sealing faucet" produced in the late 1990s. The functional structures of these two faucets have their own advantages and disadvantages, but in terms of their sealing performance, they have not completely solved this problem. Even The theoretical service life has not been well ...

AI Technical Summary

Problems solved by technology

Therefore, its upper seal design has congenital deficiencies and is not accepted by the majority of users.

[0004] 2. At the end of the 1990s, my country developed a "ceramic seal faucet", which effectively solved the problem of seal leakage on the "screw lift faucet". There are still insurmountable disadvantages in the sealing performance of the valve seat in the valve body

Whether it is "outside leakage" or "inside leakage", it brings great troubles to people's life and spirit, and a lot of waste of very precious water resources and economic losses
