Abstract
The utility model discloses a special T-shaped three-way gas valve which mainly comprises a T-shaped three-way valve body and a valve ball. The valve ball is connected into an inner cavity of the T-shaped three-way valve body, a port is further arranged on the T-shaped three-way valve body, and a valve stem which is connected with the valve ball can extend out of the port. One of two coaxial gas channel ports on the T-shaped three-way valve body is provided with external threads, the other gas channel port on the T-shaped three-way valve body is provided with internal threads, and a third port of the T-shaped three-way valve body is provided with external threads. The special T-shaped three-way gas valve has the advantages that a tee, two connecting pipes and two valves in the prior art are replaced by the valve, seven joints on original pipelines are replaced by three joints, the external threads at one end of the special T-shaped three-way gas valve are connected with a gas stove by a pipeline after an internally threaded end of the valve is connected with a gas meter, the external threads at the other end of the valve is connected with a water heater by a pipeline, and accordingly the special T-shaped three-way gas valve has an effective pipeline integrating function; opening and closing labels of the valve are concentrated and are clear; potential accidents of gas leakage can be reduced owing to reduction of the joints, the service safety and the mounting efficiency can be improved, and the mounting time can be saved; the material cost of the valve is lower than the material cost of the two valves and the tee which are connected with one another in the prior art.
Description
Technical field
The utility model relates to a kind of Special purpose valve for gas, is specifically related to a kind of and the matched T-shaped special three-way valve of domestic gas meter.
Background technique
In Household gas pipeline, after gas meter, conventionally first connect a tee pipe fitting and two gas valves, and then connect gas cooker and water heater at present.Complexity is installed, and joint is many, has increased leakage hidden danger; Installation cost is higher simultaneously.
Model utility content
The purpose of this utility model is to provide a kind of combustion gas safe, that conformability is strong special T-shaped triple valve.
The special T-shaped triple valve of the disclosed this combustion gas of the utility model, mainly comprises T-shaped three way valve and be connected in the valve ball in its inner chamber, is also useful on the interface that the valve rod that is connected with valve ball stretches out on T-shaped three way valve.
A band outside thread on described T-shaped three way valve in two blast tube interfaces of coaxial line, another is with internal thread, the 3rd interface band outside thread.
The longitudinal center line points of intersection coincide of three blast tube interfaces on the center of described valve ball and described T-shaped three way valve, has on valve ball and three T-shaped holes that blast tube interface position is corresponding.
Between described valve ball and T-shaped three way valve, filling has sealing seat, prevents gas leakage.
Described two are circumscribed with blocking cap with one in outside thread blast tube interface by sealing gasket, are connected to for be connected tapped bonnet with gas meter in the blast tube interface with female end.In the time only needing to use an external gas cooker of blast tube interface or water heater, shut one of them external screw joint by blocking cap.
Between described valve rod and T-shaped three way valve, filling has O RunddichtringO, and the outer end of valve rod is connected with handle.
The utility model replaces a threeway, two sections of connecting tubes and two valves of prior art by a valve, make three mutual UNICOMs of orthogonal pipeline and cut-out, the effect of playing shunting and damming, make seven joints on former pipeline become three joints, after the internal screw end of valve is connected with gas meter, the outside thread of one end connects gas cooker by pipeline, and the outer silk of the other end connects water heater by pipeline, integrate function pipeline chamber, clear in the keying identification sets of valve.The minimizing of joint has reduced gas leakage hidden danger, improves safety in utilization, also improves installation efficiency, saves the installation time.The cost of material of a valve also connects the cost of material of a threeway lower than two valves of prior art simultaneously.
Brief description of the drawings
Fig. 1 is that an embodiment's of the utility model master looks cross-sectional schematic.
Fig. 2 is the perspective view of T-shaped three way valve in Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, the special T-shaped triple valve of the disclosed this combustion gas of the utility model the utility model, comprise T-shaped three way valve 1 and be connected in the valve ball 2 in its inner chamber, on T-shaped three way valve 1, have four interfaces, an interface 11 stretching out for the valve rod 3 being connected with valve ball 2, other three interfaces are blast tube interface, a band outside thread in two interfaces of coaxial line, another is with internal thread, the 3rd interface band outside thread.The longitudinal center line points of intersection coincide of three blast tube interfaces on the center of valve ball 2 and T-shaped three way valve 1, has on valve ball 2 and three T-shaped holes that blast tube interface position is corresponding.
Between valve ball 2 and T-shaped three way valve 1, filling has sealing seat 4.In two blast tube interfaces of coaxial line, be with externally threaded interface to be circumscribed with blocking cap 6 by sealing gasket 5, in another, connect and be connected tapped bonnet 7 with gas meter.
Between valve rod 3 and T-shaped three way valve 1, filling has O RunddichtringO 8, and the outer end of valve rod 1 is connected with handle 9.Between valve rod 1 and handle 8, be connected and fixed by round head bolt 10 and Huang Zhu 11, round head bolt 10 is threaded with the outer end of valve rod 1, and the yellow pearl 11 of round head bolt 10 external application plastics covers, and prevents from getting rusty.
The female end of three blast tube interfaces is connected with gas meter, other two blast tube interfaces can be communicated with respectively gas cooker and water heater, only need to use a passage if temporary transient, an external screw joint can be shut for subsequent usely with blocking cap, in the time that needs use, blocking cap be taken off and connects pipeline.On valve body, the switching of interface is selected to drive valve ball pivotal position to realize on hand by rotation.
Replace a threeway and two valves of prior art by a valve, make three mutual UNICOMs of orthogonal pipeline and cut-out, the effect of playing shunting and damming, make seven joints on former pipeline become three joints, after the internal screw end of valve is connected with gas meter, the outside thread of one end connects gas cooker by pipeline, and the outer silk of the other end connects water heater by pipeline, integrate function pipeline chamber, clear in the keying identification sets of valve.The minimizing of joint has reduced gas leakage hidden danger, improves safety in utilization, also improves installation efficiency, saves the installation time.The cost of material of a valve also connects the cost of material of a threeway lower than two valves of prior art simultaneously.The switch mark of valve is concentrated clear, easy operating.If gas cooker or water heater need maintenance, only need close this valve.
