Description
Technical field
The utility model relates to a kind of high temperature resistant three drain tap, belongs to valve switch manufacturing technology field.
Background technology
At present, valve more conventional on market has ball valve, butterfly valve, gate valve, and these traditional valve generally existings valve
Door and processing are more complicated, and volume is big, it is impossible to change the deficiency of discharge directions, also there is following drawback：（1）Heat-resisting temperature
Degree is low：Because the topmost valve base sealing loop material of ball valve is politef, it has to almost all of chemical substance is
It is inert, and with coefficient of friction is little, stable performance, the synthesis that non-aging, temperature applicable range is wide and sealing property is excellent
Property feature.But the physical characteristics of politef, including the higher coefficient of expansion, the sensitivity and bad conduction of heat to cold flow
Property, it is desirable to the design of valve base sealing have to be around these characteristics to be carried out.So, when encapsulant is hardened, the reliability of sealing
Just destroyed.And, the temperature resistant grade of politef is relatively low, can only use in the case of less than 180 DEG C.More than this temperature
Degree, encapsulant will be aging.And in the case of considering life-time service, it is general only to use at 120 DEG C.（2）High cost：
Traditional valve fittings are more, complex structure, processing technique complicated.（3）Open and close required torque larger.（4）Overall dimensions and unlatching
Highly larger, the space of required installation is also larger.Therefore it provides a kind of resistant to elevated temperatures three-way exhaust valve that can change discharge directions
There is realistic meaning.
The content of the invention
The purpose of this utility model is to provide a kind of high temperature resistant three drain tap, overcomes existing for conventional exhaust valve
Heat resisting temperature is low, high cost, and accessory is more, complex structure, processing technique are complicated, and it is larger to open and close required torque, overall dimensions and opens
Open highly larger, the also larger deficiency in the space of required installation.
Foregoing invention purpose is achieved, and is because employing following technique measures, a kind of high temperature resistant three drain tap,
Including outer valve, air inlet, left bank QI KOU and right air vent, in the valve body cavity of outer valve inner, valve inner core, institute are provided with
Stating valve inner core has a valve inner core to be sealed end, and the relative other end is valve inner core air inlet, during valve inner core is cylindrical
Sky, is provided with valve inner core gas outlet on the side wall of valve inner core, is sealed above end in valve inner core and is provided with control valve
The control shaft that door inner core is rotated.
This utility model of above-mentioned measure is taken, using the structure design pattern of science, using valve inner core through 180 degree
The direction for rotating to switch gas flowing, the YE for being possible with 12-220V switch over to realize electrically operated valve.This
Utility model does not have the glue envelope of conventional valves, with heat-resisting quantity, can be applicable in the high gas extraction system of temperature such as automobile exhaust
System.This utility model simple structure, small volume are lightweight, and consumptive material is saved.Fluid resistance is little, opens and closes required torque less.Gas
Close property is good, and the gap precision of outer valve and valve inner core can reach 0.01mm, without the need for being sealed with glue.

Blue 12, outer valve is sealed end 13, control shaft pilot hole 14.
Specific embodiment party
As shown in Figure 1 and Figure 2, main body of the present utility model is outer valve 1, and air inlet 2 and a left side are provided with outer valve 1
Air vent 3, right air vent 4, left bank QI KOU 3 and right air vent 4 are in opposite direction two air vents, and this is to adapt to difference
Set by requirement of the equipment to discharge directions, the gas entered from air inlet 2 both can be discharged from left bank QI KOU 2, it is also possible to
Discharge from right air vent 3.The other end relative with air inlet 2 is that outer valve is sealed end 13, is sealed the center at end 13 in outer valve
Position is provided with control shaft pilot hole 14, for assembling the control shaft 10 on valve inner core 6.As shown in figure 3, outer valve 1 is interior
Portion is a valve body cavity 5, is equipped with valve inner core 6, between having between 6 outer wall of 1 inwall of outer valve and valve inner core inside valve body cavity 5
Gap, gap are 0.01-0.015 millimeters.The valve inner core 6 as shown in Fig. 2, Fig. 5 has a valve inner core to be sealed end 7, and which is relative another
One end is valve inner core air inlet 8, and valve inner core 6 is cylindrical hollow, on the side wall of valve inner core 6 is provided with valve inner core
Gas outlet 9, is sealed above end 7 control shaft 10 for being provided with the rotation of control valve inner core 6, on valve inner core 6 in valve inner core
Control shaft 10 be sealed end 13 through outer valve, protrude from outside outer valve 1, in control shaft 10 install joystick 11, lead to
