Abstract
The utility model relates to a glass steel valve well and a well cover, which are mainly used to install on a road, a highway and other ground where the motorized vehicle or non-motorized vehicle possibly run on or park, and is characterized in that the utility model consists of a well cover 1, a valve well support 2, and valve well casings 3, 4, wherein, the upper part of the well cover (1) is a plane surface, the surface of which is provided with a convex anti-slippery grain, character and pattern, a minisize opening hole is reserved; the bottom of the well cover (1) is provided with an opening prevention device (5); the valve well casings (3,4) are embedded with reinforced ribs (8), the valve well casings (3, 4) are connected through a bolt (10). Because the utility model adopts the glass steel as the material, and the opening prevention device is arranged, only a special matching opening tool can be used for opening, in this way, the utility model is characterized in corrosion resistance, a strong flexibility and anti-theft, etc.
Description
Technical field:
The utility model relates to a kind of glass fiber reinforced plastic valve well and well lid, is mainly used in to be installed on road, highway and other is motor-driven or bicycle may travel or park the ground.
Background technology:
At present, pipeline facilities such as water supply in the city, combustion gas, heating power all need mounted valve to control, and the method that majority is taked is after pipeline, valve are laid the installation end, assemble with brick earlier or concrete casting making valve well, and well lid protected is installed again.What also have makes valve well in advance with concrete, metal, covers valve then, and well lid protected is installed above again.These valve wells and well lid all exist different defectives: metal product is easily stolen, easy-to-rust; Concrete prefabricated heaviness is shaky again; The well lid that has also exist wear no resistance, easily cracked, carrying is low, it is inconvenient change to safeguard, brings huge hidden danger to vehicle and pedestrian's safety.
Summary of the invention:
In order to overcome the problem of above-mentioned existence, the utility model provides a kind of corrosion-resistant, antitheft a kind of glass fiber reinforced plastic valve well and well lid.
The technical scheme of a kind of glass fiber reinforced plastic valve well of the utility model and well lid is: with glass fiber and glass felt is reinforcing material; with the unsaturated polyester resin is stock; with gel coating resin; curing compound; accelerator and high-abrasive material etc. are auxiliary material; adopt brand new technical schemes such as BMC/SMC and artificial auxiliary operation; the implementation layering is compound; sectional making and integral cast die press technology for forming (being called for short FFZ); under specified temp and pressure, solidify; use special equipment and forming method; with material at former; formpiston or to making design shape on the mould; apply certain external force then; make the resin impregnated reinforcing material; solidify under specified temp, finally demould carries out the parts that post-production is made to be needed again.。During use parts are installed on the pipeline and both can.Connect fixedly antiunlocking device of miniature open hole, pre-buried fixture owing to adopt to reserve, the valve repaired uses supporting special opening instrument to open, and other people can't at will open; Adopt pre-buried well lid, bearing to connect the annex mode in the forming process, make finished product in use open freely, time saving and energy saving.
The beneficial effects of the utility model are: because main raw material(s) is nonmetals, the processing of employing special process, save the engineering time, have corrosion-resistant, pliability is strong, characteristics such as antitheft, can replace cast iron, concrete and other to assemble the various occasions that valve well is used, adopt to reserve fixedly antiunlocking device of miniature open hole, built-in fitting, the maintenance management personnel advantages such as convenient and long service life of working have stopped to have now on the market drawback of valve well and well lid.
The specific embodiment:
Fig. 1: be the structure chart of a kind of glass fiber reinforced plastic valve well of the utility model and well lid
Wherein 1, well lid 2, valve well bearing, 3 (4), valve well housing 5, antiunlocking device 6, pipe hole 7, valve installation place (valve well inside) 8, reinforcing rib 9, coupking shaft 10, bolt
Below in conjunction with the drawings and specific embodiments, a kind of glass fiber reinforced plastic valve well of the utility model and well lid are described further.The utility model is not limited to following examples.
With reference to accompanying drawing, the utility model is made up of well lid (1), valve well bearing (2), valve well housing (3,4), antiunlocking device (5), pipe hole (6), valve installation place (valve well inside) (7), reinforcing rib (8), coupking shaft (9), bolt (10).Wherein well lid (1) top is the plane, the surface is provided with anti-skidding line and the literal, figure word of projection, and leave miniature open hole, well lid (1) bottom is provided with antiunlocking device (5), well lid (1) is connected with valve well bearing (2), valve well housing (3,4) by coupking shaft (9), the valve well housing is embedded with reinforcing rib (8) on (3,4), and the both sides of valve well housing (3,4) have pipe hole (6), and valve well housing (3,4) connects by bolt (10).Mounting method: select two housings (3,4) parts earlier, it is enclosed within on valve and the pipeline, make valve place valve installation place (valve well inside) (7), pipeline places pipe hole (6), with valve well housing coupling bolt (10) valve well housing (3,4) is linked, well lid (1) is installed, is used coupking shaft (9) its binding.Using method is: put down well lid (1) and make it to lie in a horizontal plane on the valve well bearing (2), the antitheft opener of special use is passed through the well lid open hole, put in the open hole of antiunlocking device (5), the special-purpose antitheft opener of pull-up, make it to combine with antiunlocking device (5), the stator of turn antiunlocking device (5), make in its headspace that enters valve well bearing (2) top, unclamp special-purpose antitheft opener, take out special-purpose antitheft opener, well lid promptly is locked on the valve well bearing (2), and he can't open by other instruments of human, and device plays anti-unlatching effect.During unlatching the antitheft opener of special use is passed through the well lid open hole, put in the open hole of antiunlocking device (5), the special-purpose antitheft opener of pull-up, make it to combine with antiunlocking device (5), the stator of turn antiunlocking device (5) screws out stator from the headspace on well lid bearing (2) limit, the special-purpose antitheft opener of pull-up, well lid (1) and valve well housing (3,4) are separated, can carry out maintenance and inspection.
