Definitions
- the invention relates to control valves, in particular, to thermostatic valves for heating devices (radiators, convectors, etc.).
- thermostatic valves for example, according to patents of the Russian Federation
- the thermostatic valve from the description of the German patent DE ⁇ 3529614 contains a housing on which a rod is installed, protruding outward through the gland to actuate the valve closing element, an upper thermostatic part containing a thermostatic element (TSE) and a pusher moved by it, while the pusher head interacts with the stem.
- TSE thermostatic element
- TSE can be filled in the form of saturated steam and works depending on the vapor pressure (which depends on temperature), in the form of a liquid (and, therefore, works depending on its thermal expansion), and also in the form of waxy materials.
- the stem performs reciprocating motion under the action of TSE, moving the valve from open to closed.
- the compensation spring prevents the valve from breaking.
- stem seals made in the form of rubber O-rings are the most vulnerable spot due to their wear due to the friction of rubber on the metal of the stem, which is aggravated by the impurities contained in the coolant. Since the failure of the seals leads to leakage of the coolant and the gulf of the room, such thermal vents must be periodically maintain, namely replace these seals. Their replacement requires the overlapping of the coolant line, at least its partial discharge and qualified analysis of the valve.
- the movement of the valve mainly depends on the filling material used by the thermostatic head, but also depends on the size and type of aneroid box, for example, a bellows.
- the best gains of the available thermostatic valves are about 0.35 mm / 1 0 C for steam fillers and from 0.2 to 0.28 mm / 1 0 C for liquid ones.
- the prototype contains a housing, a stem, stem seals in the form of two rubber rings.
- the sealing rings should be installed with an interference fit, but then the thermal valve characteristic starts to depend on friction (hysteresis occurs), and the rings wear out quickly, i.e. they have a limited resource.
- these seals quickly fail, losing their tightness; dirt getting between the stem and the saddle leads to a misalignment of the stem, which also leads to uneven compression of the rings and, as a consequence, to a violation of the tightness.
- the objective of the invention is to improve the accuracy of regulating the flow of coolant thermostatic valve by eliminating the influence of pressure of the coolant, as well as improving reliability through the use of seals in the form corrugated membrane, eliminating friction between moving elements.
- the problem is solved in that in a thermostatic valve containing a movable stem interacting with a thermostatic head on one side and with a smaller arm of the travel reinforcement lever, and a larger arm of the travel amplifier lever interacts with a valve that is installed with a gap with respect to the seat, the non-fluid cavity is sealed flexible corrugated membrane, and the lever of the power amplifier is passed through the corrugated membrane.
- 1 1 is the lever of the power amplifier; 12th; 13 non-fluid cavity.
- the movable stem 6 interacting with the thermostatic head 5 is passed through fitting 4, while the axis of symmetry of the movable rod 6 coincides with the axis of symmetry of the thermostatic head 5 and fitting 4.
- the movable rod 6 interacts with the smaller arm of the travel amplifier 11 mounted on an axis 12 located in the non-fluid cavity 13.
- a valve 7 is fixed to the larger arm of the travel amplifier 11 with a clearance relative to the seat 8, which allows it to move more than the moving rod 6.
- the axis 12 perceives the force arising on the corrugated membrane 9 from the pressure of the liquid (coolant), thereby unloading the movable rod 6 from the action of internal pressure.
- This thermostatic valve operates as follows.
- the thermostatic head 5 acts on the movable rod 6, moving it in the vertical direction.
- the movable rod 6, interacting with the smaller lever arm of the travel amplifier 11, transfers the movement of the movable rod 6 to the larger lever arm of the amplifier 11, reporting movement of the valve 7 toward the seat 8, reducing the gap between them.
- the flow of fluid (coolant) through the thermostatic valve, and, therefore, through the heating device decreases and the room temperature is restored in accordance with the set value.
- the thermal head 5 ceases to act on the movable rod 6 and the system of “valves - travel amplifier lever - movable rod” comes to its original position under the action of a spring 10, which transfers force through the amplifier of the stroke 11 to the movable rod 6 and valve 7.
- the sealing of the non-fluid cavity 13 in the housing 1 along the movable element is carried out by a flexible corrugated membrane 9, which minimizes the force arising on the travel booster 11 arm.
- the industrial design of the proposed thermostatic valve is simple, using proven structural elements and proven technologies.
