Detailed description of the invention
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained on the premise of not making creative work, broadly fall into the scope of protection of the invention.
As shown in Figure 1, a kind of Anti-freezing water meter that the embodiment of the present invention provides, including watchcase 1, specifically, is provided with gauge assembly 4 setting up and down and cartridge assemblies 5 in watchcase 1 in the present embodiment, the lower half of watchcase 1 is provided with heat-insulation layer 2, and the bottom in watchcase 1 is provided with the cushion chamber 3 of a closing.During low temperature due in watchcase 1 lower portion be provided with heat-insulation layer 2, and the top half in watchcase 1 is without heat-insulation layer 2, the first half can first freeze, the ice volumetric expansion of top half the latter half expansion in watchcase 1, owing to the mounting structure of cartridge assemblies 5 with watchcase 1 forms isolation strip above cartridge assemblies 5, the latter half of watchcase 1 gradually freezes, effect due to isolation strip, the latter half of watchcase 1 freezes and will not form extruding to upper half demi-inflation, the cushion chamber 3 of freezing and expansion extruding bottom, the latter half, cushion chamber 3 absorbs the pressure from ice, thus realize water pressure in freezing process in water meter and will not significantly increase, protection water gage glass and other parts of water meter will not be extruded by force and rupture and damage.
Further, in the present embodiment, the end face of cushion chamber 3 is an elastica 31, and elastica 31 is connected by the bottom surface of back-moving spring 32 with cushion chamber 3.Specifically, the present embodiment Elastic film 31 is preferably and uses the elastomeric material being applicable to drinking water to make.Elastomeric material can be thermoplastic elastomer, and thermoplasticity silicone rubber has good physical and mechanical properties, resistance to water and thermo oxidative stability.The elastica 31 being provided with and back-moving spring 32 pressure by ice can compress downwards when low temperature, and when temperature rises, in water meter after ice-out, the pressure in water meter reduces, and elastica 31 is upspring, squeezed away by water by back-moving spring 32, can be returned to conventional sense.
Further, in the present embodiment, heat-insulation layer is located at watchcase, heat-insulation layer 2 includes barrier assembly 21 and is embedded in the insulation material 22 within barrier assembly 21, the barrier assembly 21 current in isolating and heat-insulating material 22 and water meter.Heat-insulation layer 2 can also be arranged on the outside of watchcase 1 in both can being arranged on watchcase 1, heat-insulation layer 2 is located at the internal installation being easy to heat-insulation layer 2 of watchcase 1, heat insulation effect is preferable, for avoiding the insulation material 22 impact on water quality, heat-insulation layer 2 is provided with the barrier assembly 21 for completely cutting off insulation material 22 and current, the barrier assembly 21 being provided with can directly be embedded in described watchcase 1, simplifies the installation of heat-insulation layer 2, and more attractive in appearance compared to the outward appearance that heat-insulation layer 2 is arranged on the outer water meter of watchcase 1.
Further, in the present embodiment, heat-insulation layer 2 is located on the medial wall of watchcase 1, and the bottom of cushion chamber 3 is lower house 33, and elastica 31 is connected by back-moving spring 32 with the inner bottom surface of lower house 33, and the edge of lower house 33 is tightly connected with barrier assembly 21.Only being provided with heat-insulation layer 2 on the medial wall of watchcase 1, the bottom of watchcase 1 is owing to having cushion chamber 3, and the air conduction in cushion chamber 3 is slow, can play certain insulation effect, therefore, it can save and arranges heat-insulation layer 2 bottom watchcase 1.Cushion chamber 3 bottom is provided with independent lower house 33, it is simple to the fixed installation of elastica 31.Specifically, in the present embodiment, cushion chamber 3 is located at the lower section of heat-insulation layer 2, and the lower section at lower house 33 edge is provided with pressing plate 34, for lower house 33, elastica 31 and heat-insulation layer 2 being tightly connected.Using pressing plate 34 directly lower house 33, elastica 31 and heat-insulation layer 2 to be compressed and serve the effect being tightly connected, mounting structure is simple.
Further, in the present embodiment, barrier assembly 21, lower house 33 are plastic material with pressing plate 34.Due to the characteristic that plastic material heat conduction is slow, barrier assembly 21 uses plastic material to make the icing rate that can reduce under low temperature with lower house 33 etc..
Further, in the present embodiment, the lower section of cushion chamber 3 is provided with the sealing plate 6 that the lower seal with watchcase 1 is connected.The bottom of watchcase 1 arranges sealing plate 6 and can play a protective role, and the lower house 33 of plastic material can be avoided to damage under external force, improves the life-span of water meter.Specifically, in the present embodiment, the junction of sealing plate 6 and watchcase 1 is provided with sealing ring 61.
Last it is noted that above example is only in order to illustrate technical scheme, it is not intended to limit；Although the present invention being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
