Abstract
The utility model relates to a liquid and a gaseous mechanical type control by temperature change fire prevention valve, including the valve rod, valve cap, retaining ring, hasp, fusible material or temperature sensing deformation material, swivel nut, spring, case, valve body, its characterized in that: fusible material or the directness of temperature sensing deformation material and valve cap contact and place in between the valve cap inboard and the hasp outside.
Description
Technical field
This utility model relates to a kind of mechanical temperature control fire resisting damper of fluid and gas.
Background technology
At present, common temperature control fire resisting damper such as the embodiment 9 in patent ZL201520660118.7, embodiment 10, its fusible material or heat responsive deformation material are placed in spool, and there is between spool and shell certain interval, cause external heat can not be directly conducted to melt material or heat responsive deformation material by shell thus affect heat-transfer rate.Temperature sensing sensitivity is the highest the most to external world.
Summary of the invention
Technical problem to be solved in the utility model is to provide simple in construction, the mechanical temperature control fire resisting damper higher to ambient temperature perceptual sensitivity.
This utility model relates to a kind of mechanical temperature control fire resisting damper of fluid and gas, including valve rod, bonnet, back-up ring, snap close, fusible material or heat responsive deformation material, swivel nut, spring, spool, valve body；It is characterized in that: described fusible material or heat responsive deformation material directly contact with bonnet be placed in inside bonnet and outside snap close between.
This utility model is compared with prior art, have the advantages that simple and reasonable, owing to using fusible material or heat responsive deformation material directly to contact the structure being placed between bonnet and snap close with bonnet, make temperature-sensing valve that the ambient temperature perceptual sensitivity indirect heat transfer compared with ZL201520660118.7 to be significantly improved.
Accompanying drawing explanation
Fig. 1 is that this utility model embodiment 1 spool extrusion type temperature control is from closing the pipe gas main sectional view of temperature control fire-proof valve structure.
Fig. 2 is that this utility model embodiment 2 spool pulls formula temperature control from closing cylinder for liquefied gas temperature control from closing the main sectional view of angle valve structure.
Detailed description of the invention
Embodiment 1: see Fig. 1, the present embodiment mainly includes valve rod 1, bonnet 2, back-up ring 3, snap close 4, fusible material or heat responsive deformation material 5, swivel nut 6, spring 7, spool 8, valve body 9.
The present embodiment is that Household pipe gas temperature control is from closing manual switch valve, wherein valve rod 1 hexagon ring is down through bonnet 2, withstand on shoulder face in bonnet 2 above back-up ring 3, swivel nut 6 is suitable for reading be placed in bonnet 2 in and clasp swivel nut neck groove with snap close 4, then block the cylindrical of snap close 4 with fusible material or heat responsive deformation material 5；In spring 7 is placed in swivel nut 6 and make lower spring end withstand swivel nut 6 inner bottom part, spring 7 upper end is withstood below back-up ring 3.In on spool 8, outer-hexagonal inserts valve rod 1 hexagon ring, spool 8 is threaded onto swivel nut 6 screwed hole, and bottom swivel nut, outer-hexagonal inserts the inner hexagonal hole of valve body 9 to stop swivel nut to rotate；Bonnet 2 is threaded onto on valve body 1, and within shoulder compress and realize heatproof and firmly seal.During rotation valve rod 1, while valve rod 1 hexagon ring band movable valve plug 8 hexagonal rotates, spool 8 screw thread relies on swivel nut 6 female thread to move linearly up and down along axis to realize hand switch action.Under room temperature state: fusible material or heat responsive deformation material 5 block snap close 4 and pin the cervical region of swivel nut 6 with snap close 4, pin the spring 7 descending thrust for swivel nut 6 simultaneously.When ambient temperature rises to the fusing point of fusible material or heat responsive deformation material 5, spring 7 promotes swivel nut 6 descending and pushes the arc surface of snap close 4 with the cervical region inclined-plane of swivel nut 6 open, squeezes the fusible material of thawing or heat responsive deformation material 5 to trigger trip action simultaneously.Spring 7 promotes spool 8 to close valve by swivel nut 6 simultaneously.
Embodiment 2: see Fig. 2, the present embodiment mainly includes valve rod 10, bonnet 11, fusible material or heat responsive deformation material 12, snap close 13, spring 14, swivel nut 15, valve body 16, spool 17.
The present embodiment is that cylinder for liquefied gas temperature control closes angle valve certainly, and basic structure is essentially identical with principle and embodiment 1.Only on the basis of embodiment 1, swivel nut is changed into pulling formula structure for the push-press type structure of spool.
Although this utility model is open as above with embodiment; but it is not limited to protection domain of the present utility model, mutually reconfigures than the different structure between each embodiment as described herein or the valve body in above-described embodiment is incorporated among other products so that other products possesses temperature control holding function.In a word, any technical staff being familiar with this technology, the change made in without departing from spirit and scope of the present utility model and retouching, protection domain of the present utility model all should be belonged to.
Claims (1)
1. a mechanical temperature control fire resisting damper, including valve rod, bonnet, back-up ring, snap close, fusible material or heat responsive deformation material, swivel nut, spring, spool, valve body；It is characterized in that: described fusible material or heat responsive deformation material directly contact with bonnet be placed in inside bonnet and outside snap close between.
