Specific embodiment
The embodiments of the present invention is described further with reference to the accompanying drawing.
The specific embodiment of the cooling line overflow valve of the utility model, as shown in Figure 1 to Figure 3, which includes
Valve seat 1 and the valve deck 5 being tightly connected with valve seat 1, valve seat 1 surround the valve chamber 10 being connected to cooling line, valve deck with valve deck 5 jointly
Have on 5 for being connected to valve chamber 10 and extraneous valve port 4, is equipped in valve chamber 10 under the pressure of coolant liquid in cooling line
Cooperation close port 4 is sealed with valve port 4 and separates and open under the effect of external force the spool of valve port 4 with valve port 4, in the present embodiment
Spool is valve ball 2, and 5 activity of valve deck is assemblied on valve seat 1, and valve deck 5 has on valve seat 1 makes spool active configuration in valve chamber 10
Spool moving position and so that spool is fixed on the fixed position of spool in valve chamber 10 and with the sealing cooperation of valve port 4.
In the present embodiment, as shown in Figure 1 to Figure 2, valve seat 1 and valve deck 5 be two make-ups columnar structured, valve seat 1
The valve chamber 10 for placing valve ball 2 is surrounded with valve deck 5, valve chamber 10 is connect with cooling line by fluid inlet 3, and valve seat 1 is horizontally mounted
The water outlet of motor 7 in cooling line.In order to connect valve deck 5 simply with valve seat 1,5 inner peripheral surface of valve deck is equipped with internal screw thread,
1 outer peripheral surface of valve seat is equipped with external screw thread, and valve deck 5 is connect with valve seat 1 by thread seal, and valve deck 5 and valve seat 1 can pass through rotation
Position of the valve deck 5 on valve seat 1 is adjusted into the number of screw thread.Opening of the tool operation channel in valve seat 1 in the present embodiment
For valve port 4, staff can protrude into tool from tool operation channel and valve ball 2 is pushed to open interface channel, in other embodiments,
Tool operation channel can also be set in the side of exhaust passage, at this time in order to guarantee the leakproofness of overflow valve, tool operation is logical
Sealing structure should be set between road and pushing tow tool, and pushing tow tool can also be assembled on valve seat, constitute one of overflow valve
Point.In other embodiments, external screw thread can also be set in valve deck outer peripheral surface, internal screw thread is arranged in valve seat inner peripheral surface.In other realities
It applies in example, valve deck can also be attached by flange or buckle etc. with valve seat.
In order to enhance the sealing effect of overflow valve, when valve deck 5 is in spool fixation position in the present embodiment, valve ball 2 and company
The sealing cooperation of the fluid inlet of port valve chamber 10 and cooling line is to close interface channel.Valve port 4 and fluid inlet be and valve at this time
Ball 2 seals, and valve ball 2 and interface channel constitute first of sealing, and valve ball 2 and valve port 4 constitute second sealing, and sealing effect is more
By force.In other embodiments, it can also only allow valve ball 2 and valve port 4 to seal, should also be carried out between valve seat 1 and valve deck 5 at this time close
Envelope.
As shown in figure 3, water outlet of the overflow valve in addition to the motor 7 that may be mounted in cooling line, can also pass through
Rigid structure is connected to the water outlet of the other component in cooling system, for example, the electric machine controller 8 in cooling line go out
At the mouth of a river, it can also be connected to by flexible conduit on cooling pipe 9.
When, there are when excessive gas, needing for gas in pipeline to be discharged, staff is by screwing at this time in cooling line
Valve deck 5 adjusts position of the valve deck 5 on valve seat 1 and is operated when gas is recycled to overflow valve in cooling line by staff
Tool push valve ball 2 separate valve ball 2 with valve port 4, gas by communicating passage enter valve seat 1 through around valve ball 2 again from valve port 4
Outflow.After gas discharge, coolant liquid flow to overflow valve, is pushed at valve port 4 and sealing ring in the pressure lower valve ball 2 of coolant liquid
6 cooperation sealings, close valve port 4, finally screw valve deck 5 to the fixed position of spool, so that valve deck 5 and valve seat 1 is squeezed valve ball 2 and carry out
Sealing.The present embodiment apparatus structure is simple, is not restricted, is operated conveniently, working efficiency by factors such as professional equipments in actual use
It is obviously improved.
The embodiment of the vehicle of the utility model, vehicle include vehicle frame, are installed with cooling line on vehicle frame, on cooling line
Equipped with overflow valve, the overflow valve in the present embodiment is identical as the overflow valve structure in above-mentioned specific embodiment, repeats no more.
