Including an aqueduct, aqueduct is open at one end, the other end is closed；
Expansion tank connection interface tube is located on aqueduct, and water compensating valve interface is located on aqueduct, expansion tank connecting tube
The axis of interface and the axis of water compensating valve interface are vertical；
Further include the draining valve body and drain plug being located on aqueduct, drains the axis and water circulating pump interface of valve body
Axis is overlapped；The valve chamber of drain plug and draining valve body cooperates.
It is described it is a kind of with drainage arrangement for return water valve body, be characterized in that the drain plug includes circular cone
Shape core portion, hollow valve stem open at one end and the drainage hole being located in valve stem；Valve stem is equipped with external thread part；Outer spiral shell
The diameter in line portion is greater than the diameter of valve stem；
The draining valve body and aqueduct junction are equipped with valve core case, and valve core case is equipped with water-guiding hole；
The internal screw-thread screw of the external thread part of valve stem and the valve chamber；Truncated cone core portion and water-guiding hole cooperate, circle
Gap between valve stem and valve chamber between taper type core portion and external thread part constitutes water guide drainage gap.
The utility model it is a kind of with drainage arrangement for return water valve body, the setting of drain valve, heating system need blowdown or
When changing water, drain valve only need to be opened, it is easy to use.
Detailed description of the invention
Fig. 1 is the perspective view of the utility model.
Fig. 2 is the partial sectional view of the utility model.
Fig. 3 is the cross-sectional view of the utility model drain valve hull-borne.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.
As shown in Figure 1, it is a kind of with drainage arrangement for return water valve body, including water supply valve body 1, return water valve body 2 and will supply water
The bypass pipe 3 that valve body and return water valve body link together, water supply valve body 1 connect including heating water water inlet interface 11, heating water water outlet
Mouth 12, hydraulic pressure switch interface 13, temp probe interface 13, pressure gauge connection 15 and the interface being connect with by-pass；Return water valve body 2
Interface tube 23, water circulating pump interface 24, moisturizing are connected including heating return water water inlet interface 21, relief valve interface 22, expansion tank
Valve interface 25 and the interface being connect with bypass pipe.
The heating return water water inlet interface 21 and water circulating pump interface 24 further include an aqueduct point-blank
26, aqueduct 26 is open at one end, the other end is closed；
Expansion tank connection interface tube 23 is located on aqueduct 26, and water compensating valve interface 25 is located on aqueduct 26, swelling water
The axis of case connection interface tube 23 and the axis of water compensating valve interface 25 are vertical；
Further include the draining valve body 27 and drain plug 4 being located on aqueduct 26, drains the axis and recirculated water of valve body 27
The axis of pump interface 23 is overlapped；The valve chamber of drain plug 4 and draining valve body 27 cooperates.
The drain plug 4 includes conical core portion 41, hollow valve stem 42 open at one end and is located in valve stem
Drainage hole 43；Valve stem 42 is equipped with external thread part 421；The diameter of external thread part 421 is greater than the diameter of valve stem 42；
The draining valve body 27 is equipped with valve core case 28 with 26 junction of aqueduct, and valve core case 28 is equipped with water-guiding hole；
The external thread part 421 of valve stem 42 and the internal screw-thread screw of the valve chamber；Truncated cone core portion 41 and valve core case
