Abstract
The utility model relates to a constant temp. open-close valve, which comprises a temperature-sensing element, a sleeve pipe with an inlet opening, a carrier rod, a valve body with thread, a valve plug, and a return spring. The temperature-sensing element 8 is arranged on one end of the sleeve pipe 7 with the inlet opening. The connection of the other end of the sleeve pipe 7 and the valve body is a threaded connection. The valve plug 6 is fixedly arranged on the carrier rod 5, and is directly fixed by the return spring 4. One end of the carrier rod 5 is assembled with the pushing rod of the temperature-sensing element. The other end of the carrier rod 5 is supported by a retaining ring 2 which is arranged in the valve body 1 and a pad 3 with an outlet. The return spring 4 is arranged between the valve plug 6 and the pad 3. The utility model has the advantages of simple structure, reliable operation, and convenient installation. The utility model can be used in occasions which require the homothermal condition, such as the food industry, the chemical industry, etc.
Description
The utility model relates to a kind of constant temperature open valve, belongs to the temperature control valve.
That Chinese patent CN91205150.7 discloses is a kind of " solar water reset thermostat valve ", and it is by the inductor assembly, valve assembly, and long push rod assembly is brought the sleeve pipe in water hole into, and flange plate and Returnning spring are formed.Its valve assembly is made up of the port of the valve pad of nut check and sleeve pipe.Its flange plate is also by nut check.Returnning spring is contained between the anchor plate of long push rod assembly and the flange plate.The shortcoming of the thermostat valve of this structure is as follows: the first, complex structure, difficulty is installed, and its installation in pipeline realizes by flange plate or union.The second, because its valve pad and flange plate all are fastening with nut, therefore, in long-term the use, because the loosening of nut can influence temperature-controlled precision.
The purpose of this utility model is at above-mentioned shortcoming of the prior art, and provides a kind of simple in structure, simple installation, the constant temperature open valve of reliable operation.
The purpose of this utility model is to realize like this, it is by heat responsive element, bring the sleeve pipe in water hole into, valve body, valve plug and the Returnning spring of push rod, band pipe thread are formed, heat responsive element 8 is loaded on an end of the sleeve pipe 7 of bringing the water hole into, the water inlet of the other end of sleeve pipe 7 and valve body 1 is a scyewed joint, valve plug 6 is fixedly mounted on the push rod 5, and directly push up solid by Returnning spring 4, push rod 5 one ends are equipped mutually with the push rod of heat responsive element, its the other end is by ring washer 2 that is positioned at valve body 1 and pad 3 supportings of taking the water hole out of, and Returnning spring 4 is contained between valve plug 6 and the pad 3.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
As seen from the figure, the utility model is by heat responsive element 8, brings the sleeve pipe 7 in water hole into, push rod 5, valve plug 6, and Returnning spring 4, valve body 1, ring washer 2 is taken the pad 3 in water hole out of and is formed.Heat responsive element adopts 1800 type heat responsive elements, is a kind of standard component, and it is by inductor, heat sensitive material, and rubber pipe, push rod and sebific duct cover constitute.The temperature control scope from 30-110 ℃ optional, control temperature can reach ± 1.5 ℃.
Heat responsive element 8 is loaded on an end of the sleeve pipe 7 of bringing the water hole into, uses scyewed joint.The water inlet of the other end of sleeve pipe 7 and valve body 1 is for being threaded.Valve plug 6 is fixedly mounted on the push rod 5, and is directly pushed up admittedly by Returnning spring 4, and push rod 5 one ends are equipped mutually with the push rod of heat responsive element 8, and its other end is by ring washer 2 that is positioned at valve body 1 and pad 3 supportings of taking the water hole out of.Returnning spring 4 is contained between valve plug 6 and the pad 3.
Working principle of the present utility model is as follows:
When temperature is elevated to when opening temperature, the push rod of heat responsive element 8 backs down valve plug 6 by push rod 5, liquid by the orifice flow on sleeve pipe 7 walls through valve.Open temperature when following when temperature is reduced to, the heat sensitive material of heat responsive element 8 shrinks, and loses top power.Because Returnning spring 4 directly acts on the behind of valve plug 6, so valve closing.
The tight power of giving of Returnning spring 4 should be greater than rated working pressure 23kg/cm
2, make valve when low temperature, be in closed condition.Pressure reduction down-off at 0.04Mpa can reach 2.5 liters/minute.Sleeve pipe 7 is changeable, to satisfy the requirement of different occasions.Be shaped on standard pipe thread on the valve body 1, be convenient to install.
The utility model has the advantages that simple in structure, reliable operation, volume is little in light weight, simple installation, this valve can be widely used in food, chemical industry, boiling water room etc. require the occasion of constant temperature.
