Abstract
The utility model relates to a temperature-control stop valve which is composed of a valve body, a valve cover, a connecting sleeve tube, valve flaps, a valve rod, a spring, a pressure pin, etc. The utility model is characterized in that the lower end of the valve rod is provided with two valve flaps which respectively control two discharge outlets on an inlet tube, and liquid pressure which is borne by the two valve flaps can be mutually counteracted. The opening and the closing of the temperature-control stop valve are decided by the function of the controlled pressure of a temperature sensor, and the size of the controlled pressure is decided by the temperature of a controlled object. Consequently, the utility model ensures that the opening and the closing states of the temperature-control stop valve are controlled by the temperature at all times without influencing by any other elements basically. Thus, the temperature-control stop valve has the advantages of reliable action, stable performance, high control precision, no vibration, no noise and simple structure.
Description
The utility model relates to stop valve, more specifically says so to belong to a kind of stop valve of controlling by temperature transducer.
In the prior art, temperature control stop valve (as RTC/RTD-N type preset valve, RTD-G type high-performance valve), be single valve seat, spring and often open stop valve, its structure more complicated, particularly the temperature control stop valve is like Kai Feikai, and during like the transition state of Guan Feiguan, flap will be because of bearing fluid pressure (before the valve with valve after pressure reduction) influence jumpy, make the temperature control stop valve be in unstable working state, may produce vibration, noise and control temperature error and increase.Therefore, the temperature control stop valve in the prior art, to before the valve with valve after pressure reduction strict demand has all been proposed, in order to satisfy this requirement, in pipe network system, usually need to take multiple technologies measure and equipment, as need defferential valve etc. is installed.
The purpose of the utility model temperature control stop valve design is, provide a kind of be not subjected to before the valve with valve after magnitude of pressure differential influence, do not produce vibration, noise free, stable performance, control accuracy height, simple in structure, temperature control stop valve that technology capability is good.
Above-mentioned task is often to open stop valve and realize by the bivalve seat (bivalve lobe), the spring that are located in the valve body: the temperature control stop valve is made up of institutes such as valve body, valve gap, adapter sleeve, flap, valve rod, spring and press-on pins, it is characterized in that the valve rod lower end is equipped with two flaps, two drain opening on the control valve seat are cancelled out each other two fluid pressures that flap bore respectively.
This structure has guaranteed mainly to bear the making a concerted effort very little or approach zero of two fluid pressures that flap bore of temperature control stop valve, its valve rod and flap spring force, sealing surface resistance and from the effect of temperature transducer pilot pressure.Because of the sealing surface resistance less relatively, and change not quite, and spring force changes also smaller under the less condition of resiliently deformable, so stop valve play, close major decision from the temperature transducer pilot pressure, the size of its pilot pressure is that the temperature by controlled device is determined.So just guaranteed that the temperature control stop valve plays, closes state and controlled by temperature, not influenced by other factors.Therefore, a kind of temperature control stop valve has: reliable in action, does not produce vibration, noise free, characteristic of simple structure at stable performance, precision height.
Some other characteristics of the present utility model will be illustrated further by following example narration.
Below in conjunction with accompanying drawing, introduce the utility model embodiment.
Accompanying drawing is the axial sectional view of a kind of temperature control stop valve of the utility model.
Being described as follows of each label among the figure:
The 1-valve body, 2-flap, 3-valve rod, 4-spring, 5-adapter sleeve, 6-valve gap, 7-press-on pins, 8-drain opening.
By temperature control stop valve and temperature transducer organic assembling, realize thermostatically control.The temperature control stop valve play, close the size (size of its pilot pressure by the temperature of controlled device determined) of major decision from the temperature transducer pilot pressure, the pilot pressure that temperature transducer produces leads to press-on pins (7) and passes to valve rod (3).When the controlled device temperature was lower than setting temperature, the pilot pressure that temperature transducer produces was during less than spring force and sealing surface resistance, and the elastic force of spring (4) promotes valve rod (3) and also is with flap (2) to move up, and valve opening increases, until maximum opening; When the controlled device temperature equals setting temperature, when the pilot pressure that temperature transducer produces equals spring force and sealing surface resistance, valve rod (3) and flap (2) transfixion, valve opening is constant, is in steady-working state; When the controlled device temperature is higher than setting temperature, the pilot pressure that temperature transducer produces is during greater than spring force and sealing surface resistance, the pilot pressure that temperature transducer produces promotes valve rod (3) and drives flap (2) to move down by press-on pins (7), valve opening reduces, till drain opening (8) is closed.
Claims (1)
1 one kinds of temperature control stop valves, form by valve body (1), flap (2), valve rod (3), spring (4), adapter sleeve (5), valve gap (6), press-on pins institutes such as (7), it is characterized in that: two flaps (2) are equipped with in valve rod (3) lower end, respectively two drain opening (8) on the control valve seat.
