a regulating valve

Abstract

The invention provides a regulating valve. The regulating valve is arranged in a connector of a pipe network system for use. The connector is provided with an internal thread. The regulating valve is mainly composed of a valve seat, a valve body, a spring and a regulating rod. The valve body further comprises a conical head and a valve rod. The conical head is conical. The cone vertex faces the outlet end. As the regulating valve is installed in the connector of an existing pipe network system, a straight or cross screwdriver can be inserted into a tool hole in a regulating head to rotate, so that the position of a regulating rod in a regulating hole in a pressing block is changed, the prestress of the spring is changed accordingly, force needed for pushing the valve body into an inner hole of a boss is changed, and the flow in unit time can be regulated from the outlet end.

Description

Technical field [0001] The invention relates to a regulating valve used for regulating the flow of fluid in a pipe network system, in particular to a regulating valve capable of regulating the flow from an outlet end, and belongs to a technology for flow control in a pipe network system. Background technique [0002] If there are multiple outlet ports in the tap water pipe network, oil pipe network and gas pipe network, even if the diameter of the outlet port is the same, the pressure of the fluid at different locations is different, resulting in the amount of fluid flowing out of the outlet ports at different locations per unit time They are not the same, and even quite different. [0003] For example, the connection between water pipes and the connection between water pipes and faucets are all realized through joints. There are generally two ways to supply water to buildings. One is to use a booster pump to deliver water from the bottom up, and the other is to place a water tank...

AI Technical Summary

Problems solved by technology

The disadvantage is that in the process of use, since the setting of the water output is adjusted from the water inlet, and the adjustment effect can only be obtained by installing the joint on the water pipe network, when repeated adjustments are required to achieve a satisfactory water output, it must be disassembled repeatedly This is not only troublesome and inconvenient to adjust; especially for home users, due to the different uses of each faucet, the requirements for water output are also different, such as the kitchen faucet, the bathroom faucet and the shower head, etc., due to the difference in use , the requirements for water output are also different. For example, it is enough to keep the water output of the faucet at 4 liters per minute, while the water output of the shower head is required to be above 8 liters per minute. Therefore, users also need to adjust the maximum output of each faucet. If it is adjusted from the water inlet, you need to repeatedly remove the relevant equipment, adjust it, install it, and try again until you are satisfied. The operation time is too long, and disassembly and assembly are also troublesome. For concealed installation It is more difficult to disassemble the joints in the wall
