Specific embodiment
It elaborates with reference to the accompanying drawing to the utility model.
Thermostat valve as shown in Figure 1 to 11, including water outlet tube socket 1, push rod 2, inside is filled with temperature-sensing wax and left end is opened
Temperature-sensitive spool 3, spring 4, O-ring seal 5, water inlet tube head 6 and spring card 7 equipped with guide groove, are discharged tube socket 1 and water inlet pipe
First 6 be plastic part, and the shell of temperature-sensitive spool 3 is brass material, and heat transfer effect is superior.
As shown in Figures 1 to 7, it is discharged to be provided on the outer wall of tube socket 1 and is used to indicate thermostat valve opening direction and liquid flow
To arrow logo 18, water outlet tube socket 1 left end have taper type water outlet connector 19, water outlet tube socket 1 in Openworks shape branch
Support 11 and the tube socket sealing surface 15 cooperated with temperature-sensitive spool 3, the right part of water outlet tube socket 1 are offered about water outlet tube socket 1
The right part inner wall of two card slots 16 of axisymmetrical, water outlet tube socket 1 has second level limited step 17, and it is close that support frame 11 is located at tube socket
15 left side of cover, the center of support frame 11 offer the push rod slot 12 cooperated with push rod 2, and the hollow out position of support frame 11 is formed out
Water hole 13, the edge of tube socket sealing surface 15 offer overflow hole 14.
As shown in Figure 1 to Figure 4, shown in Figure 10, Figure 11, the left end of water inlet tube head 6 is circumferentially evenly arranged with three guiding along tube wall
Item 61, the left part outer wall of water inlet tube head 6 have second level positive stop lug boss 62, and a circle is offered on second level positive stop lug boss 62 for assembling
The groove 63 of O-ring seal 5, for O-ring seal 5 in groove 63, the right end of water inlet tube head 6 has taper type water supply connector
64。
As shown in Figures 1 to 4, intake tube head 6 left part protrude into water outlet tube socket 1 right part in, second level positive stop lug boss 62 with
The cooperation of second level limited step 17 is against two card bases of spring card 7 are inserted into respectively in two card slots 16, by tube head 6 of intaking
The right part clamping of left part and water outlet tube socket 1, and sealed by O-ring seal 5, push rod 2, temperature-sensitive spool 3, spring 4 are located at water outlet
In tube socket 1, in the left end insertion push rod slot 12 of push rod 2 and 12 clearance fit of push rod slot, the right end of push rod 2 are inserted into temperature-sensitive spool 3
Guide groove in, the right part of spring 4 covers outside three gib blocks 61, and right end and water inlet tube head 6 left side against spring 4
Rest part cover outside temperature-sensitive spool 3, and the step of left end and 3 left part of temperature-sensitive spool is against temperature-sensing valve when spring 4 is compressed
The right end of core 3 can protrude into the space that three gib blocks 61 surround.
The assembling steps of above-mentioned thermostat valve are as follows: 1) O-ring seal 5 is fitted into groove 63, and 4 sets of spring are led at three
To outside item 61；2) push rod 2 right end insertion guide groove in, temperature-sensitive spool 3 with push rod 2 towards a left side be assembled to water outlet tube socket 1 in it is intracavitary,
Ensure that the left end of push rod 2 is encased in push rod slot 12；3) in place by the water inlet tube head dispensed and water outlet tube socket compression fit, exist
It is discharged indentation spring card 7 in two card slots 16 of tube socket 1 to fasten, the rest part of spring 4 covers outside temperature-sensitive spool 3, and left
End and the step of 3 left part of temperature-sensitive spool against；So far, thermostat valve is completed.Direction shown in arrow logo 18 is also thermostat valve
Be mounted towards.
When coolant temperature is higher than setting value, temperature-sensing wax expanded by heating in temperature-sensitive spool 3, the left end of push rod 2 by
Thrust is in the bottom of push rod slot 12, and the elastic force for making temperature-sensitive spool 3 overcome spring 4 moves right, and temperature-sensitive spool 3 is gradually remote
From tube socket sealing surface 15, makes the flow channel of coolant liquid by closing out, realize the effect for gradually opening simultaneously final channel standard-sized sheet；When
When coolant temperature is lower than setting value, temperature-sensing wax cooling meat in temperature-sensitive spool 3, spring masterpiece of the temperature-sensitive spool 3 in spring 4
Reset is gradually moved to the left under, temperature-sensitive spool 3 is gradually reduced at a distance from tube socket sealing surface 15 and finally fits closely, and makes cold
But the flow channel of liquid gradually becomes smaller and finally completely closes.
The material prescription of temperature-sensing wax is different, and the response temperature of temperature-sensitive spool 3 is also different, i.e., just opens temperature and standard-sized sheet temperature tool
There is adjustability；By changing the material prescription of temperature-sensing wax, the operating temperature of adjustable temperature-sensitive spool 3 meets not homologous ray
Performance requirement.
