Straight pipe type hot and cold water valve

Abstract

The invention provides a straight pipe type hot and cold water valve which comprises an inner straight pipe and an outer straight pipe, wherein a mixed water cavity is formed between the inner straight pipe and the outer straight pipe, and a water outlet is extracted from the mixed water cavity. Through holes are bestrewed on one half circumferential wall of the inner straight pipe, and two ends of the inner straight pipe are respectively connected with a hot and cold water pipe. A separation sleeve capable of rotating around the inner straight pipe is encircled on the outer side of the inner straight pipe, and through holes are bestrewed on one half circumferential wall of the separation sleeve. A sliding sleeve is sleeved on the outer side of the outer straight pipe. A pair of magnetic poles with the magnetic interaction direction facing to the sliding sleeve diameter direction is arranged in the sliding sleeve. Two magnetic stripes along a cylindrical bus bar of the separation sleeve are arranged on the separation sleeve, and the acting force direction between the two magnetic stripes faces to the separation sleeve diameter direction. A magnetic sliding plug is further arranged in the inner straight pipe. The straight pipe type hot and cold water valve can be operated by users conveniently and can adjust water temperature continuously and accurately.

Description

[0001] technical field [0002] The invention relates to the field of valves, in particular to a cold and hot water integrated valve. [0003] Background technique [0004] In the bathroom field, it is usually necessary to provide cold water and hot water at the same time, so a combination of hot and cold water valves is required. There are two main combinations of hot and cold water valves at present. One is that the cold water valve and the hot water valve respectively control the cold water pipe and the hot water pipe. This combination can continuously and stably adjust the water temperature. One valve body, so it is more inconvenient to use; the other is the integrated hot and cold water valve, which can control the water temperature on one valve body, and is more convenient to use. However, the current integrated hot and cold water valve adopts The structural principle is: during the rotation of the spool, it goes through the process of completely blocking the hot wat...

Problems solved by technology

There are two main combinations of hot and cold water valves at present. One is that the cold water valve and the hot water valve respectively control the cold water pipe and the hot water pipe. This combination can continuously and stably adjust the water temperature. One valve body, so it is more inconvenient to use; the other is the integrated hot and cold water valve, which can control the water temperature on one valve body, and is more convenient to use. However, the current integrated hot and cold water valve adopts The structural principle is: during the rotation of the spool, it goes through the process of completely blocking the hot water nozzle - gradually opening the hot water nozzle - completely blocking the cold water nozzle, the spool is in direct contact with the hot and cold water nozzle, and Restricted by the shape of the hot and cold water nozzle and the valve core, the opening of the hot and cold water nozzle is a nonlinear process during the rotation of the valve core, that is, the opening area of ​​the hot water nozzle and the shrinking area of ​​the cold water nozzle are related to the valve The angle that the core turns is not directly proportional, so that in actual use, it is difficult to adjust the water temperature to a suitable temperature, such as the commonly used hot and cold water valves for showers, when the adjustment handle is adjusted to the middle position, or Release cold water, or release hot water all at once, in many cases it is difficult to adjust the reasonable water temperature
