Specific embodiment
The utility model is described in detail with reference to the accompanying drawing.
As shown in Figure 1, the utility model thermostat valve self-action thermostat valve, has hot-side inlet A, cold-side inlet B and blends Tri- ports mouth C, are mainly made of valve casing 1, valve seat 2, regulating nut 3, spool 4 and sealing ring 5 etc., and parallel configuration 1 may be selected A or multiple identical spools 4 are needed with adapting to different flow (carrying out the Parallel Design of spool 4 according to A, B, C port pipe diameter size) It asks, therefore self-action thermostat valve provided by the utility model has the broad applicability of very big flow range.The present embodiment is with two valves Core 4 carries out carrying out structure explanation for parallel connection.Each spool 4 includes temperature sensing package 41, reset spring 46, spool push rod 42, spool bottom Seat 47, spool bushing 43, overload spring 44, spool sliding sleeve 45;Spring retainer block 4501 is fixed in spool sliding sleeve 45.Valve casing 1 uses three way type structure;Be equipped with hollow cavity inside valve casing 1, the hollow cavity respectively with cold-side inlet B, hot-side inlet A and mixed Outlet C is closed to be connected.Two 4 parallelly distribute ons of spool in the hollow cavity of above-mentioned valve casing 1, and be located at nearly cold-side inlet B, At hot-side inlet location A;The temperature sensing package 41 of two thermostatic valve cores is respectively positioned in the hollow cavity of valve casing, nearly mixed export position Place.The valve core base 47 of spool 4 is fixed in valve casing, and spool sliding sleeve 45 is slidingly disposed in hollow cavity.Spool push rod 42 one end are equipped with spring tray 48, and the end is connected with temperature sensing package 41, and 42 other end of spool push rod is successively worn freely slidablely Cross valve core base 47, spool bushing 43, spring retainer block 4501.43 side of spool bushing passes through restoring link 49 and spring tray 48 sides are fixedly linked.Reset spring 46, overload spring 44 are respectively sleeved in 42 both ends of spool push rod;46 both ends of reset spring difference Contradict reset spring 46 and valve core base 47;44 both ends of overload spring contradict spool bushing 43 and spring retainer block 4501 respectively. 45 inner hollow of spool sliding sleeve, both ends open.Valve core base 47 is equipped with fluid channel.
The spool 4 of thermostat valve has different movements in different temperature, and spool 4 has a temperature sensing package 41 at C port, is used for Fluid temperature (F.T.) at C port is perceived, the material that temperature sensing package uses is very sensitive to temperature change, as temperature is expanded with heat and contract with cold.Work as temperature When degree is lower than a DEG C of temperature, spool push rod 42 is not pushed out, and spool bushing 43 is affixed on valve core base 47, and overload spring 44 is in Nature, spool sliding sleeve 45 are bonded under the action of gravity itself with valve core base 47, spool bushing 43 and spring tray 48 It is connected by restoring link 49, reset spring 46 is also at nature (as shown in Figure 1 and Figure 2) at this time;With the liter of temperature Height, spool push rod 42 are gradually released, and overload spring 44 is compressed, when the compressed spring force of overload spring 44 is sliding equal to spool When the gravity of set 45, spool bushing 43 will leave valve core base 47 with overload spring 44 and spool sliding sleeve 45 this entirety; When temperature continues to be increased to b DEG C, spool push rod 42 will push slide core bushing 43 with overload spring 44 and spool sliding sleeve 45 this A entirety is begun to move up, and reset spring 46 also starts to be compressed at this time;Continue to increase with temperature, spool push rod 42 will Slide core bushing 43 is pushed to begin to move up with overload spring 44 and spool sliding sleeve 45 this entirety, and reset spring 46 is also got over More to be compressed;When temperature reaches c DEG C, spool sliding sleeve 45 is pushed on the valve seat 2 of thermostat valve (as shown in Figure 2);Work as temperature Continue to increase, slide core valve pocket 45 is irremovable, and spool push rod 42 will push spool bushing 43, so that overload spring 44 and reset bullet The continuation of spring 46 is compressed, and overload spring 44 and reset spring 46 shield at this time, prevent spool push rod 42 and spool sliding sleeve 45 etc. are subject to crushing.When temperature is from when beginning to decline for c DEG C, spool bushing 43 will move down under the spring force of reset spring 46, Start to move down with overload spring 44 and spool sliding sleeve 45 this entirety, until spool push rod 42 is pressed into this temperature Equilbrium position;When temperature drops to b DEG C, slide core sliding sleeve 45 will stick valve core base 47 again again;When temperature continues to decline, valve Core sliding sleeve 45 is immovable, and spool push rod 42 is pressed into this temperature for spool bushing 43 is passed through under the spring force of overload spring 44 The equilbrium position of degree, until spool bushing 43 is affixed on valve core base 47 when temperature drops to a DEG C, overload spring 44 is in certainly Right state.The temperature sensing package 41 of spool 4 ceaselessly experiences oil temperature, and has different movement and aperture according to temperature is experienced constantly. State when spool 4 is lower than b DEG C is known as cold conditions, and state when higher than c DEG C is referred to as hot.When x DEG C of set temperature of thermostat valve After determination, spool 4 can be set, generally setting b=x-5, c=x+5, i.e., setting thermostatic valve core 4 x DEG C of set temperature with Lower 5 DEG C start to act, and reach aperture maximum value at x DEG C of set temperature or more 5 DEG C.When spool 4 is cold conditions, thermostat valve A and C port It communicates;Spool 4 between cold conditions and it is hot when, the port A and B is communicated with C port;When spool 4 is hot, B and C port are communicated. Thermostat valve according to temperature constantly regulate hot fluid through the port A to C port and through the cold fluid flow proportional of the port B to C port, Keep the fluid temperature (F.T.) flowed out after being sufficiently mixed from C port precisely controlled.Thermostat valve is internal temperature-sensing valve, uses three way type Design, both can ensure that in temperature controlled processes, initial stage fluid temperature (F.T.) when low all fluids through the port A flow to C port, with The most short temperature feedback time is obtained, in turn, ensures that system fluid flow is constant.Reliable firm structure becomes thermostat valve to temperature Change sensitive, the interference for being not easily susceptible to pressure change and fluctuating suddenly, to keep stable outlet temperature under various operating conditions Degree.When needed, by adjusting regulating nut 3 valve seat 2 can be pasted extremely on the spool sliding sleeve 45 of spool 4, so that thermostat valve A and C port force it is obstructed, so that fluid is all flowed through cooler, pressure cooling carried out to it.In addition, can be in spool sliding sleeve 45 It is upper to drill to allow the fluid flowing for having a small amount of between the port A and B, the reason is as follows that: the 1. small flow materials of permission are in spool 4 Cooler is flowed to when cold conditions, to slow down warm-up cycle;2. small flow hot fluid is allowed to flow to the port B from the port A, and keep one Constant flow, to prevent condensation or freeze in extreme circumstances;3., must when spool 34 is in cold conditions in the case where the port A blocks There must be leak to ensure small flow, so that temperature sensing package 41 can experience temperature change, thermic load equipment be allowed to run.This is practical The self-action thermostat valve of novel offer uses the mechanical structure that is made of components such as valve casing, valve seat, spool and regulating nuts, not by Power constraints can constantly automatically adjust spool aperture according to temperature using itself mechanism, temperature control quick and precisely, and its spool movement Reciprocally reappear, also can the spool dilatation flow scope of application in parallel, simple structure, design stability and durable.
