Description

A kind of thermostat valve

Technical field:

The utility model relates to a kind of valve, particularly a kind of thermostat valve.

Background technique:

Existing self-supporting temperature-sensing valve generally is equipped with the PT100 temperature transducer, and the working principle of this temp controller is temperature sensing liquid volumetric expansion or contraction; Thereby the unlatching of control valve or close; The shortcoming that this temp controller structure exists, the one, volume is bigger, is inappropriate for the installation conditions of small space; Temperature sensing liquid is high to seal request, is not suitable for special occasions.

Summary of the invention:

The purpose of the utility model provides a kind of volume a kind of thermostat valve little, simple in structure and applied widely.Realize that the utility model purpose technological scheme is; A kind of thermostat valve; Comprise valve casing, valve and telescopic spool; It is characterized in that: valve casing top is provided with two symmetrical radial holes and is connected with the pipeline of coolant system and the import of heat exchanger respectively, and the bottom of this valve casing is provided with a radial hole and is communicated with the liquid outlet of heat exchanger, and the axial bore cunning at the valve of the annular canister of upper end closed and said valve casing middle part is joined; The center hole cunning of the tubular spool of lower end closed and the valve of said annular canister is joined; Step body lower end surface on this valve core places on the upper-end surface of said annular canister valve, and the top of said tubular spool is a pipe, and this pore is communicated with the cavity of tubular spool; In the cavity of this tubular spool, be filled with the heat sensitive wax composite material; The guide rod cunning fits in the pore on said tubular spool top, the top and bottom of this guide rod be connected with the upper end cap of valve casing respectively with annular canister spool cavity in the heat sensitive wax composite material contact, between the inner core lower end surface of said annular canister valve and the spring seat on the said valve casing lower end sheet, be provided with spring; On the axial bore at the valve casing middle part adjacent, be provided with step hole with the radial hole on said valve casing top; This step hole is connected with the radial hole on said valve casing top, and the axial bore and the inner chamber of said valve casing that are evenly equipped with on the outer tube wall of said annular canister valve on radial hole and the spring seat are communicated with, and the axial bore of said spring seat is communicated with the cooling liquid pipeline.The utility model and existing technology relatively have little, the simple in structure advantage applied widely of volume.

Description of drawings:

Fig. 1 is the systematic schematic diagram of the utility model valve closing state, and Fig. 2 is the systematic schematic diagram of the utility model valve open state.

Embodiment:

In conjunction with above-mentioned accompanying drawing the utility model is described in detail, the temperature control element that the utility model adopts is solid-state temperature-sensitive material, and this thermostat valve is made up of valve casing 5, last end cover 8, spool 11, valve 12, spring 15; Its concrete structure is; Be respectively equipped with relative radial hole 9,16 in the upper and lower of valve casing, valve 12 is slided in the hole that fits over the valve casing middle part, and the upper end in the hole in the middle part of this valve casing has a step hole to link to each other with the radial hole 9 on valve casing top; This valve is the annular canister of upper end closed; On the outer tube wall of this valve, be evenly equipped with radial hole 13, the outer tube wall of the tubular spool 11 of lower end closed is provided with on the upper-end surface that step body places above-mentioned valve, and the top of spool is provided with a pipe; This pore is communicated with the cavity of spool; In this spool cavity, fill solid-state expanding material 14, guide rod 10 sliding fitting in the pore on above-mentioned spool top, the lower end surface of guide rod contacts with solid-state expanding material in the spool cavity; Its upper end is connected with the upper end cap of valve casing; On the lower end surface of valve casing, be provided with spring seat 17, this spring seat center is provided with the outer liquid road of axial bore and valve casing and is communicated with, and spring 15 places between the lower end surface and the annular end face on the stepped cylinder on the said spring seat of inner tube wall of valve; On the upper and lower stomidium of valve casing, be respectively equipped with a circular groove and circlip matches, these two circlips are respectively applied for the upper end cap and the spring seat of standing valve.Said solid-state expanding material is the heat sensitive wax composite material; Its production firm is Fushun, a Liaoning Province wax industry Co., Ltd, and the fusing point of this heat sensitive wax composite material is 110 ℃, and its expansivity is 13-15% under 55 ± 5 ℃; This heat sensitive wax composite material is in the allowable temperature scope, and its extending amount is 8-10mm.

The working principle of the utility model, on the pipeline before heat exchanger 7 liquid entering holes in the thermostat valve access coolant system of the utility model, cooling liquid heater via 1, flowmeter 2, thermometer 3 and pressure gauge 4 get in the thermostat valve valve casings 5; Thermostat valve is open mode in the temperature of cooling liquid during for normal temperature; Cooling liquid flows directly into tank for coolant by the temperature control valve pocket and lowers the temperature without heat exchanger, and along with coolant temperature constantly raises, the heat sensitive wax composite material expands and extends; Valve moves down gradually the runner hole is turned down; Part cooling liquid flows into tank for coolant by the cavity of resorption of thermostat valve after flowmeter 6 gets into heat exchanger 7 coolings, and another part directly gets into tank for coolant, if the oil temperature continues to raise; The open degree of valve diminishes gradually; The cooling liquid measure that gets into heat exchanger strengthens, and closes fully up to valve, and all cooling liquid is flowed through and got into tank for coolant (referring to Fig. 1) after heat exchanger is lowered the temperature.The spool that this solid-state expanding material is done need not seal swelling liquid, and is simple in structure, make easily, and long service life, easy to maintenance.
