Abstract
The utility model discloses a fluid flow control valve is answered to heat sensitive sets up mobilizable piston in its valve seat, the hinge joint heat -sensitive sheet removes about the deformation promotion piston through the heat -sensitive sheet to fluidic flow in the control flap seat. Use the temperature of this control valve adjustment heating equipment or air conditioner, make heating gas more even, set for through restricting the valve highest temperature to save excessive thermal energy consumption.
Description
Technical field
This utility model is related to valve technology field, specifically a kind of control valve with regard to controlling fluid flow
Door part.
Background technology
For heating equipment or air-conditioning, the regulation of temperature is required for controlling valve controls fluid supply.Than
As, the Central Heating Providing in the north, place close to supply centre for the user, heat is often excessive, away from heating point
Place, heat is very few.Conventional control valve is quantitative (such as faucet), can be only opened to
A certain degree, changes without the change according to temperature.Conventional control valve is to be positioned by screw thread,
Such as faucet.
Utility model content
In order to solve the problems, such as prior art, this utility model provides a kind of Purely mechanical, temperature-sensitive
The flow control valve of sensing.
In order to realize object above, the technical solution adopted in the utility model is：A kind of thermal sensing fluid
Flow control valve, is made up of valve seat, piston and heat-sensitive sheet, and setting in described valve seat is movably lived
Plug, piston connects heat-sensitive sheet, promotes piston to move left and right by the deformation of heat-sensitive sheet, thus control valve
The flow of fluid in seat.
Insulated shaft is set between described piston and heat-sensitive sheet.
Compared with prior art, this utility model thermal sensing fluid flow control valve is due in valve seat
Setting heat-sensitive sheet, senses, by heat-sensitive sheet, the position of the switch that ambient temperature change carrys out regulating piston, can adjust
Whole heating equipment or the temperature of air-conditioning, make more uniform for heating installation, are set by limiting to the valve highest temperature,
To save excessive thermal energy consumption, it is applied to all environment by liquid or gas transmission heat.
The utility model has the advantages that：1st, do not need to use power supply it is not necessary to use electronic component,
It is not provided that can also realize the regulation to temperature during power supply controls, applied range；2. because there is no electricity
Subcomponent, so stability is high, relatively reliable.
Brief description
Fig. 1 is the structural representation of thermal sensing fluid flow control valve.
Specific embodiment
As shown in figure 1, thermal sensing fluid flow control valve by valve seat 1, piston 2, heat-sensitive sheet 3,
Insulated shaft 4 and screw putter 5 form.
Plant piston 2 in valve seat 1, piston can move left and right.The moving direction of piston 2 and valve seat 1
Middle fluid flow direction is mutually perpendicular to.Piston 2 connects insulated shaft 4, and insulated shaft 5 connects heat-sensitive sheet 3.Heat
Contact with outside ambient air for quick 3, Induction Air Temperature.Heat-sensitive sheet 3 is installed on screw putter 5,
The position of heat-sensitive sheet can be finely tuned.
Valve seat 1 is divided into plunger shaft 6 and pushrod chamber 7.Pushrod chamber 7 wall body offers passage 8, makes heat
Quick is contacted with outside ambient air.Pushrod chamber 7 afterbody wall body opens up screwed hole, and this screwed hole arranges spiral shell
Stricture of vagina push rod 5.
Operation principle is：Piston moves left and right so that valve closing or open.Screw putter combines heat-sensitive sheet
Deflection, the height of controlled temperature can be adjusted.Valve seat and piston select bad heat conductor, make to lead to
The heat of the liquid or gas of crossing valve does not affect heat-sensitive sheet, but the temperature of surrounding air impact heat-sensitive sheet,
Being allowed to control makes precisely.
Hot open type：1st, when a certain position, temperature rises heat-sensitive sheet shape to the right to screw putter, and piston is to the right
Mobile, open piston, valve is opened.
2nd, adjust screw putter, so that piston and heat-sensitive sheet is all moved to the left, need heat-sensitive sheet have bigger to
Right deformation, just can make piston reach open position, thus realizing the regulation to temperature of temperature-sensitive control valve
Control.
Cold open type：Identical with hot open type, heat-sensitive sheet phase direction to be installed. during temperature drop, metal is to the right
Deformation, opens piston, valve is opened.
Claims (2)
1. a kind of thermal sensing fluid flow control valve it is characterised in that：By valve seat, piston and temperature-sensitive
Piece forms, and arranges moveable piston, piston connects heat-sensitive sheet, by heat-sensitive sheet in described valve seat
Deformation promote piston move left and right, thus in control valve gate seat fluid flow.
2. thermal sensing fluid flow control valve according to claim 1 it is characterised in that：Described
Insulated shaft is set between piston and heat-sensitive sheet.
