Technical field
The utility model relates to a kind of composite exhaust valve, especially a kind of anti-bursting by freezing clean water composite exhaust valve.
Background technique
Clean water composite exhaust valve is for the special-purpose intake and exhaust device in row's feedwater piping, is widely used in the waterline, and a large amount of exhausts during water filling are closed after having arranged and do not sluiced aperture exhaust when normally moving, air inlet destruction vacuum during vacuum.The main effect of clean water composite exhaust valve is the normal operation that improves emptying effectiveness and protection pipe network.Often owing to paste ground or buried installation, in the time of-30 ℃～0 ℃, therefore volumetric expansion bursting by freezing when valve body or valve gap build-up ice because of water can't guarantee the normal operation of pipe network to existing clean water composite exhaust valve under the weather of extreme cold.
The model utility content
The purpose of this utility model is to solve existing clean water composite exhaust valve can't guarantee the normal operation of pipe network under the weather of extreme cold problem.
The technical solution adopted in the utility model is: a kind of anti-bursting by freezing clean water composite exhaust valve, it comprises main valve body, little valve body, be connected with valve gap on the main valve body, the valve gap periphery is provided with the lifting screw that main valve body and valve gap are connected, be connected with exhaust hood on the valve gap, the main valve body inner chamber is provided with the nylon guiding trestle, be connected with floating drum on the nylon guiding trestle, be connected with little valve lid on little valve body, little valve lid periphery is provided with little valve body and little valve is covered the little row's lifting screw that is connected, little valve covers and is connected with little row's nut, be connected with the little row's pedestal that stretches into little valve intracoelomic cavity on little row's nut, be connected with ball float on little row's pedestal, described main valve body and little valve body are fixed with one and main valve body inner chamber and little valve intracoelomic cavity are connected, the joint of main valve body and little valve body is provided with some roads stiffening rib, be equipped with locking nut on described lifting screw and the little row's lifting screw, be provided with spring between an end of described lifting screw and the locking nut, be provided with spring between one end of little row's lifting screw and the locking nut.
As further improvement of the utility model, described main valve body is cast steel WCB valve body, and little valve body is the little valve body of cast steel WCB.
As further improvement of the utility model, described floating drum is 316 stainless steel floating drums, and ball float is 316 stainless steel floating balls.
The beneficial effect that the utility model adopts is: this clean water composite exhaust valve also can normally move under the weather of extreme cold, has therefore guaranteed the normal operation of pipe network.
Description of drawings
Fig. 1 is the utility model schematic representation.
Fig. 2 is the plan view of Fig. 1.
Shown in the figure: 1 main valve body, 2 little valve bodies, 3 valve gaps, 4 lifting screws, 5 exhaust hoods, 6 nylon guiding trestles, 7 floating drums, 8 little valve lids, 9 little row's lifting screws, 10 little row's nuts, 11 little row's pedestals, 12 ball floats, 13 springs, 14 locking nuts.
Embodiment
Below in conjunction with Fig. 1, the utility model is described further.
As shown in Figure 1, the utility model relates to a kind of anti-bursting by freezing clean water composite exhaust valve, it comprises main valve body 1, little valve body 2, be connected with valve gap 3 on the main valve body 1, valve gap 3 peripheries are provided with the lifting screw 4 that main valve body and valve gap are connected, be connected with exhaust hood 5 on the valve gap 3, main valve body 1 inner chamber is provided with nylon guiding trestle 6, be connected with floating drum 7 on the nylon guiding trestle 6, be connected with little valve lid 8 on little valve body 2, little valve covers 8 peripheries and is provided with little row's lifting screw 9 that little valve body and little valve lid is connected, be connected with little row's nut 10 on little valve lid 8, be connected with the little row's pedestal 11 that stretches into little valve body 2 inner chambers on little row's nut 10, be connected with ball float 12 on little row's pedestal 11, described main valve body 1 and little valve body 2 are fixed with one and main valve body inner chamber and little valve intracoelomic cavity are connected, the joint of main valve body and little valve body is provided with some roads stiffening rib, be equipped with locking nut 14 on described lifting screw 4 and the little row's lifting screw 9, be provided with spring 13 between one end of described lifting screw 4 and the locking nut 14, be provided with spring 13 between one end of little row's lifting screw 9 and the locking nut 14, described main valve body 1 is cast steel WCB valve body, little valve body 2 is the little valve body of cast steel WCB, described floating drum 7 is 316 stainless steel floating drums, and ball float 12 is 316 stainless steel floating balls.
When the utility model used in normal temperature, the spring that lifting screw and little row go up lifting screw was in extended configuration, is suitable for the normal temperature exhaust; When using for-30 ℃～0 ℃, water in main valve body and the little valve body build-ups ice, and producing expands makes water volume increase, along with increase floating drum and the ball float of the volume of water rises, this moment valve gap, whole assembly such as exhaust hood rises along the main valve body inner chamber, simultaneously little valve lid, little row's nut, little row's pedestal, rise along little valve intracoelomic cavity Deng assembly, owing to be provided with spring between an end of lifting screw and the locking nut, be provided with spring between one end of little row's lifting screw and the locking nut, the nut compression makes body cavity and little row's cavity volume increase so spring is locked, eliminate water and build-up ice and expand the stress of generation, ensured the normal operation of clean water composite exhaust valve effectively.When temperature returns to normal temperature, the ice-out Cheng Shui that forms in main valve body and the little valve body, whole assemblies such as this moment valve gap, exhaust hood etc. descend along the main valve body inner chamber, simultaneously little valve lid, little row's nut, little row's pedestal, etc. assembly descend spring recovery extended configuration along little valve intracoelomic cavity.
In order further to strengthen the intensity of valve body, described main valve body and little valve body are fixed with one and main valve body inner chamber and little valve intracoelomic cavity are connected, and the joint of main valve body and little valve body is provided with some roads stiffening rib.Like this under the weather of extreme cold, valve body is swelling stress spalling stressed and that can not build-up ice and produce because of water evenly.
Further improve anti-low temperature ability, main valve body and little valve body adopt low temperature resistant cast steel WCB, and floating drum and ball float adopt low temperature resistant 316 stainless steels to be stamped to form.
In sum, this clean water composite exhaust valve also can normally move under the weather of extreme cold, has therefore guaranteed the normal operation of pipe network.
