Abstract
The invention relates to a totally-enclosed three-way valve having bypass mainly used in a four-tube hydraulic terminal, characterized by adopting a peaked switch 12 integrated with a switch 2 for totally closing the tube joint, thereby inducing the water flow into the bypass 7.
Description
Technical field
The present invention relates to have the Totally-enclosed three-way valve of bypass, it is characterized in that, when closing, main supply line can be closed together with the recurrent canal of heat exchanger, and is converted to by-pass pipe.
Background technique
The invention belongs to the hydrovalve field, generally can be applicable to the hydraulic pressure terminal equipment, as fan coil unit, storehouse formula equipment, or the wall-hanging wetting system.The present three-way valve of the band bypass on the common hydraulic pressure terminal equipment on the market is with after the heat exchanger power supply is connected, and delivers the fluid to heat exchanger by by-pass pipe.These valves are connected to the supplying tube and the recurrent canal of equipment respectively by interface tube 3 and interface tube 6 these two interface tubes.
Its technology uniqueness is that first interface tube 3 (often being in open mode) is connected to supply tube.Fluid enters heat exchanger by first interface tube 3 on the valve under pressure-less state, enter valve body and from interface tube 6 outflows, inject recurrent canal at last by interface tube 5 then.Use switch or an electronic switch, or hand switch is with the connection closed between interface tube in the valve 5 and the interface tube 6, fluid can pass through by-pass pipe 7, directly arrives from import 3 and exports 6.Use this switch, can open or close by-pass pipe, also can control power supply, to reach purpose of energy saving by this switch in valve inside.
The problem that this scheme exists is, when mixing valve or relevant switch are not installed, can not the while to heat exchanger hot-water supply and cold water, so that make its mixing reach needed temperature.In addition,, need to adopt two heat exchangers, be equipped with two water circulating pipes, so that can while hot-water supply and cold water for four tubular type equipment.
Summary of the invention
The objective of the invention is to solve above-mentioned all problems.
A kind of three-way valve that has bypass of the present invention is characterized in that, when valve body is in closed condition, is connected to the heat exchanger of sealing by supply tube.
In the present invention, use a pointed switch that forms as one with pin type switch that interface tube is closed fully.
In addition, use pointed switch manual or that motor switch is opened and pin type switch forms as one.
Therefore, when the four tubular type equipment of installation,, promptly can be equipped with the monomer heat exchanger, and not need additional valve, mixer or other switches if use the Totally-enclosed three-way valve that has bypass provided by the present invention.Following relevant explanation has realized above-mentioned technical problem fully.

Embodiment
Traditional valve on the structure of valve provided by the invention such as the market is made up of the master unit made from brass 1 (above 4 interface tubes are arranged).At first, interface tube 3 is connected on the supply line of equipment, and then, interface tube 4 is connected to the import of heat exchanger; Interface tube 5 is connected to the outlet of heat exchanger, and last, interface tube 6 is connected to the recurrent canal of equipment.
Under the situation that valve is all opened, as the three-way valve of traditional band by-pass pipe, its current by interface tube 4, through interface tube 3, interface tube 8, inject heat exchanger at last under pressure-less state.In the outlet of heat exchanger, enter valve body then by interface tube 5.Then, enter interface tube 6 through interface tube 9 (being in open mode), last, reenter the circulatory system by recurrent canal.Uniqueness of the present invention is the most obvious when the valve body Close All.As shown in Figure 4, pin type switch 2 (can make its rotation) is equipped with on switch 10, switch 11 and the switch 12 by manual or motor switch.When starting pin type switch, pad type switch (it presses down stroke probably for several millimeters) makes switch 10 and switch 12 that interface tube 8 and 9 is closed downwards.After depress switch, use switch 12 (have special pointed) blanked-off pipe interface 8, make current enter by-pass pipe 7, then, enter discharge pipe 6, enter recurrent canal at last.
Need explanation a bit, when part off switch 12, the part of current will enter by-pass pipe 7, and its another part will enter heat exchanger, as the three-way valve of traditional band by-pass pipe.
On the pointed switch that is adopted, be to use OR sealing gasket (non-totally enclosed type sealing gasket) to seal, see parts 13 and parts 14 that Fig. 4 demonstrates for details.
In the present invention, can directly in valve body, directly block the water supply of heat exchanger by pointed switch 12 blanked-off pipe interfaces 8.
Claims (3)
1. a three-way valve that has bypass is characterized in that, when valve body is in closed condition, is connected to the heat exchanger of sealing by supply tube.
