Abstract

Cold and hot water regulator valve is a device which can allocate fluid proportion. The utility model can control the proportion of cold and hot water at will by one valve. The valve is composed of a bent tube, a cast-iron housing, a copper bush, a copper water valve, a spanner, a cushion ring and springs. Nuts round holes are arranged on the copper bush, which are communicated with the bent tubes. A copper bush and a copper water valve are arranged in the cast-iron housings. Elongated holes with different angular is under the median line of the copper bush and copper water valve. When the pipe of hot water and cold water is switched on, various proportion of water can be controlled by pushing the spanner according to the labeled hot and cold flags and thermoregulation scale. The utility model has the advantages of convenient operation, saving time and functioning as two valves.

Description

Cold and hot water regulator

The utility model relates to a kind of valve of separating liquid device.

Existing hot and cold water allotment valve generally need adopt two valves and a three-way pipe to regulate water temperature respectively, needs during use respectively two valves to be carried out the turn-knob debugging, not only inconvenience but also time-consuming, the hot and cold water waste is many, and needs two valves and a three-way pipe are installed, and cost is higher.

The purpose of this utility model provides a kind of need can be debugged various different water temperatures arbitrarily on a valve hot and cold water temp regulation valve, and not only temperature adjustment is convenient, the waste of water when reducing temperature adjustment, and also cheap.

The utility model is finished as follows: the casting system has the cast iron housing (2) in four holes, on cast iron housing (2), leave two the nut circular holes (14), (15) that connect cold water pipe and hot-water line respectively, the copper sheathing (3) that installs and fixes in the cast iron housing (2), have cold water square hole (6) and hot water square hole (8) in the position up and down at copper sheathing (3) center line, cold water square hole (6) communicates with nut circular hole (14), and hot water square hole (8) communicates with nut circular hole (15).Two nut circular holes also can communicate with bend pipe (1).

The smooth in appearance rule is installed in the copper sheathing (3) is trapezoidal hollow activity copper water valve (4), on copper water valve (4), have rectangular cold water hole (5) and rectangular heat water hole (7), rectangular cold water hole (5) communicates with cold water square hole (6), rectangular heat water hole (7) communicates with hot water square hole (8), in the copper water valve (4) is cavity, and this chamber communicates with rectangular cold water hole (5), rectangular heat water hole (7).Copper sheathing (3) and copper water valve (4) all adopt double-deck form to be distributed in the cast iron housing (2).

The copper cylinder position of copper water valve (4) is connected to become an integral body by rivet (13) and back-up wrench (12).Mounting spring (11) between cotton yarn (9), packing ring (10), two packing rings (10) is installed on the copper cylinder position of copper water valve (4), copper water valve (4) and copper sheathing (3) is held out against, prevent to leak with the effect of spring (11).Simultaneously cold and hot sign and temperature adjustment scale are set on the hot and cold water temp regulation valve, guide for use is provided.

By the hot and cold water temp regulation valve that the utility model is manufactured, its hot and cold water current approach is: rectangular cold water hole (the 5) → copper water valve cavity on cold water square hole (the 6) → copper water valve on cold water → nut circular hole (14) → copper sheathing and mix with hot water → bend pipe (1) flows out.Rectangular heat water hole (7) → copper water valve cavity on hot water square hole (8) → copper water valve on hot water → nut circular hole (15) → copper sheathing also flows out with cold water mix → bend pipe (1).

Equate that at hydraulic pressure the hot and cold water ratio was 1:0 when the indicated position of back-up wrench was 30 ° under the situation, 40 ° is 6:1, and 50 ° is 6:2, and 60 ° is 6:3, and 70 ° is 6:4, and 80 ° is 6:5, and 90 ° is 6:6.The hot and cold water ratio is 5:6 when the indicated position of back-up wrench is 100 °, and 110 ° is 4:6, and 120 ° is 3:6, and 130 ° is 2:6, and 140 ° is 1:6, and 150 ° is 0:1.Promote back-up wrench and reach various scales position, can conveniently debug out the water of various different temperatures.
