Abstract
This invention relates to a single-way water meter for measuring pipeline system of multi-water source and single-water source, in which, a single-way control device is designed between the inlet on a shell and a filter mesh composed of a bolt, a T-shape valve core and a reset spring, the top of the T-shape valve core is a round stand, the taper of the side of the stand is the same with that of a taper face in the inlet end closing to the inlet port and the valve core rod passes through the center hole of the bolt in a motion mode, which is advantaged that it's mounted forward only to prevent the situation that meters are installed in inversion consciously or unconsciously.
Description
Technical field
The present invention relates to a kind of one-way water meter that is applicable to multi-water resources or the metering of single water supply line system.
Background technology
The water meter of commonly using is wet type no matter, and is still vertical, all can forward and reversely be installed on the pipeline, if be not intended to or oppositely installation wittingly, can not influence water supply and sewage, also be difficult for finding, but the authenticity and the accuracy of influence metering seriously can be upset normal operation control order.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of one-way water meter that is applicable to multi-water resources or the metering of single water supply line system is provided.
Technical scheme of the present invention is, a kind of one-way water meter that is applicable to multi-water resources or the metering of single water supply line system, it comprises housing, the table lid, metering mechanism, cover on the filter screen of metering mechanism outside, it is characterized in that: between water inlet on the housing and filter screen, be provided with a unidirectional control device, this device is by the inside surface plug screw that is provided with water hole that is threaded of housing water inlet end, T-valve stamen and between valve stamen and plug screw, and the back-moving spring that is enclosed within on the valve stamen bar of T-valve stamen is formed, the top of T-valve stamen is a round platform, the tapering of water inlet end internal conical surface that is right after water inlet in the tapering of frustum cone side and the housing is consistent, and the valve stamen bar of valve stamen penetrates the center pit of plug screw in mode movingly.
Describedly evenly be provided with three positive stop lug boss on greater than the circumference of back-moving spring external diameter at plug screw.
Water hole on the described plug screw evenly is provided with 3-8 along circumference.
The present invention has following advantage: can only install by forward, prevent to be not intended to or to have a mind to the generation of anti-dress water meter situation, guarantee the accuracy and the authenticity of continuous data, and compact conformation, reasonable in design.
