Water inlet valve pipe and water control valve

Abstract

The invention relates to a water inlet valve pipe which comprises a water inlet pipe and an outer pipe; a plurality of axially distributed positioning convex rings are formed on the outer surface of the water inlet pipe, and a positioning clamping groove is formed between every two adjacent positioning convex rings; the water inlet pipe is sleeved with the outer pipe, a mounting shell extending in the radial direction is formed on the outer pipe, a reset spring and a positioning plate are arranged in an inner cavity of the mounting shell, one end of the reset spring abuts against an end cover of the mounting shell, and the other end of the reset spring abuts against the positioning plate; and the positioning plate is connected with the positioning clamping groove in a clamping mode through the elastic effect of the reset spring, and the positioning plate is provided with a shifting rod which extends out of the mounting shell and is used for shifting the positioning plate to move. The water inlet valve pipe can be effectively adjusted in the height direction, especially after being used in cooperation with a water control valve, the water inlet valve pipe is convenient to install, and the installation efficiency of occasions such as a water storage tank or a flush toilet or a swimming pool can be effectively improved.

Description

technical field [0001] The invention specifically relates to a water inlet valve pipe adapted to a water valve and a water control valve using the water inlet valve pipe. Background technique [0002] Water control valves are widely used in today's society. For example, in the water storage tanks and toilet water tanks that are used in every household, the water control valve is an indispensable key part inside. The so-called water control valve, as the name implies, is a device that can automatically stop the water supply when the water in the water tank reaches a certain water level, such as "A Water Level Control Valve" with the patent number 201921640473.2 filed by the applicant on September 29, 2019.

The so-called water control valve, as the name implies, is a device that can automatically stop the water supply when the water in the water tank reaches a certain water level, such as "A Water Level Control Valve" with the patent number 201921640473.2 filed by the applicant on September 29, 2019. "patent, which discloses the working principle of this small water control valve in detail. However, in the actual sales, the collected user feedback information also highlights a rather embarrassing dilemma: that is, due to the This kind of small water control valve is used in a wide range of scenarios. For example, some users buy it back and use it in the water storage tank on the roof, and some users buy it back and use it in the water tank of the toilet. What's more, some users buy it back and use it In swimming pools, the above-mentioned use scenarios make the length requirements of the water inlet valve tubes used with the water control valve inconsistent; as an example, especially when the small water control valve mentioned in the above patent is applied to the water tank of the flush toilet In the middle,
