Abstract

The utility model discloses a cold water valve for floor heating. The cold water valve comprises a cold water valve body (1) which comprises a water inlet branch pipe (11), a water outlet branch pipe (12) and a water quantity control end (2). The cold water valve is characterized in that the cold water valve body (1) is made of aluminum alloy materials of number 6061, and the inner surface and the outer surface of the cold water valve body (1) are both coated with an oxide layer. The cold water valve effectively solves the problem that a traditional cold water valve is made of copper materials, and therefore engineering manufacturing cost is high, and also solves the problem that if a valve element of the cold water valve is made of copper materials and the valve body is made of aluminum materials, the cold water valve can be corroded more easily.

Description

A kind of floor heating cold valves

Technical field

The utility model relates to drainage pipe equipment technical field, is specifically related to a kind of floor heating cold valves.

Background technique

At present, in floor heating pipeline process of deployment, cold valves is as requisite critical component, have a very wide range of applications, traditional cold valves is made by copper product conventionally, cost is high, domestic Ye You fraction manufacturer replaces copper product production cold valves with aluminium, but there is following drawback: one, cold valves valve body is made by aluminium material, spool is made by copper product, and owing to having for a long time water in valve body as medium, the metallic material of two different electromotive forces together, aluminium material electromotive force is lower, more easily corrodes; Two, the hardness of common aluminum alloy material is lower, easily deformation in work progress, to pipeline docking bring certain unfavorable.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of floor heating cold valves, the utility model not only efficiently solves traditional cold water valve and is made by copper product, cause the problem that engineering cost is high, if and the spool that has solved cold valves is made by copper product, and valve body is made by aluminium material, cause cold valves that the problem of corrosion more easily occurs.

The utility model is achieved through the following technical solutions:

A kind of floor heating cold valves, comprise cold valves body (1), cold valves body (1) comprises water inlet pipe (11), exit branch (12) and water yield control end (2), it is characterized in that: the aluminum alloy material that described cold valves body (1) is 6061 by the trade mark is made, cold valves body (1) inner and outer surface is all coated with oxide layer.

The further Technological improvement plan of the utility model is:

Described oxidated layer thickness is 0.15 μ m～0.3 μ m.

The further Technological improvement plan of the utility model is:

Described water yield control end (2) comprises rotating ballhead (23), and rotating ballhead (23) is connected with piston (21) by piston rod (22), rotating ballhead (23) and water yield control end (2) adjustable connection of screw thread.

The utility model compared with prior art, has following obvious advantage,

One, the aluminum alloy material that the utility model is 6061 with the trade mark is as the making material of cold valves body, and the coated oxide layer of cold valves body inner and outer surface, can not cause because spool is different from valve body material the corrosion of valve body, longer service life, and material is light, hardness is high.

Two, water yield control end of the present utility model adopts rotating ballhead to carry out regulating water-quantity, and rotating ballhead arranges water yield scale value, and control accuracy is better, and rotating ballhead is coated on water yield control end, is difficult for freezing.

Accompanying drawing explanation

Fig. 1 is structural representation Fig. 1 of the present utility model;

Fig. 2 is structural representation Fig. 2 of the present utility model.

Embodiment

As Fig. 1, shown in, the utility model comprises cold valves body 1, cold valves body 1 comprises water inlet pipe 11, exit branch 12 and water yield control end 2, the aluminum alloy material that described cold valves body 1 is 6061 by the trade mark is made, cold valves body 1 inner and outer surface is all coated with oxide layer, described oxidated layer thickness is 0.15 μ m～0.3 μ m, described water yield control end 2 comprises rotating ballhead 23, rotating ballhead 23 is connected with piston 21 by piston rod 22, rotating ballhead 23 and adjustable connection of water yield control end 2 screw threads, on rotating ballhead 23, sign has scale value, user can control water-outlet quantity according to demand.

The utility model does not relate to partly all prior aries that maybe can adopt same as the prior art to be realized.
