Abstract
The utility model relates to a temperature pressure valve which comprises a valve seat (1), valve blades (2), etc., wherein, the valve seat is provided with a pressure chamber pipeline (3) and a pressure releasing pipeline (4), and the valve plates arranged on the end part of the pressure chamber pipeline (3) are pressed by a spring (13), while the pressure chamber pipeline is provided with a temperature-sensing expansion pipe (6) which is fixed with the valve seat, and an expansion ejector rod (8) arranged on the temperature-sensing expansion pipe is clung closely to the valve blades. The utility model provides a safe pressure releasing valve, especially a pressure releasing valve with the double protections of temperature and pressure, and the utility model is used for the safety protective devices which are required to be sensitive to pressure for various water heaters, boiling water stoves and water stoves.
Description
The utility model relates to a kind of Temperature pressure valve, especially the Decompression valves of temperature and pressure duplicate protection.
Be used for electric water heater, gas hot-water apparatus, solar water heater utensil, various boiler and water-heating furnace and pressure cooker etc. and all need pressure-sensitive safety protection device, when list was used the mechanical pressure pressure release, its reliability was slightly poor.Certainly more to pressure-sensitive electronic component, but releasing of pressure also needed actuating device, increased cost on the contrary, also can reduce the practicability of pressure security protective gear.In fact above-mentioned utensil must be equipped with reliable Decompression valves.
The purpose of this utility model provides a kind of safe and reliable Decompression valves, the especially Decompression valves of temperature and pressure duplicate protection.
The purpose of this utility model is achieved in that a kind of Temperature pressure valve, comprise compositions such as valve seat, valve block, valve seat is provided with pressure chamber pipeline and relief pipeline, the valve block that it is characterized in that the pressure chamber pipe end is pushed down by spring, and installation one temperature-sensitive expansion tube on the pressure chamber pipeline, temperature-sensitive expansion tube and valve seat are fixed, but the expansion push rod on the temperature-sensitive expansion tube is pressed close to mutually with valve block.
Further improvement of the utility model is that the disposable explosion-proof valve that is communicated with relief pipeline also is housed on valve seat.
Working mechanism of the present utility model is: under normal condition, contact closely with valve seat at the pressure lower valve of spring, but one meet thermal expansion or interior pressure valve block is strutted by pressure or backed down by push rod, pressure can be released.
Characteristics of the present utility model are: a kind of safe and reliable Decompression valves is provided; especially the Decompression valves of temperature and pressure duplicate protection; and automatically perform pressure release, be that a kind of various water heaters, various boiler and water-heating furnace and pressure cooker etc. of being used for are to pressure-sensitive safety protection device.Typical index is: 99-5 ℃ of hot pressure release temperature, safety relief 700-50KPa can hand-operated forced pressure release, disposable explosion-proof pressure 300+50KPa.The hot pressure release temperature of pressure cooker improves 2-5 ℃,
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment:
Fig. 1 is a structural representation of the present utility model
As shown in the figure, Temperature pressure valve comprises the valve 2 that valve seat or valve body 1, valve block constitute, valve seat is provided with pressure chamber pipeline 3 and relief pipeline 4, the valve 2 of pressure chamber pipe end is pushed down by spring 13 and by a screw 5, there is a handle to be attached thereto on the valve block simultaneously and connects, therefore can push valve aside with hand.One temperature-sensitive expansion tube 6 is installed on the pressure chamber pipeline, and temperature-sensitive expansion tube and valve seat are fixing by a screw 7, but the expansion push rod 8 on the temperature-sensitive expansion tube is pressed close to mutually with valve block 2.The temperature-sensitive pipe is that common process is made, the paraffin wax temperature sensing medium 11, the Sealing 12 that comprise spaghetti 9, bulb 10 and inner filling, Sealing top is push rod, 11 pairs 99 ℃ of paraffin wax temperature sensing mediums or 102 ℃ of sensitivities, melt and dissolved, the rapid expansion of paraffin wax this moment makes push rod 8 produce displacement, backs down valve 2 pressure releases action.The disposable explosion-proof valve (14) that is communicated with relief pipeline also is housed on valve seat.When contingency relief pipeline quilt is stifled, still can guarantee pressure release.
Claims (2)
1. Temperature pressure valve, comprise valve seat (1), valve block compositions such as (2), valve seat is provided with pressure chamber pipeline (3) and relief pipeline (4), the valve block that it is characterized in that pressure chamber pipeline (3) end is pushed down by spring (13), and installation one temperature-sensitive expansion tube (6) on the pressure chamber pipeline, temperature-sensitive expansion tube and valve seat are fixed, but the expansion push rod (8) on the temperature-sensitive expansion tube is pressed close to mutually with valve block.
2. by the described Temperature pressure valve of claim 1, it is characterized in that on valve seat, also being equipped with the disposable explosion-proof valve (14) that is communicated with relief pipeline.
