Abstract
The invention discloses a small-diameter water meter shell made of a PPO (poly-p-phenylene oxide) material. The small-diameter water meter shell comprises a water outlet connecting nut, a meter shell body and a water inlet connecting nut, wherein a sensor mounting opening and a valve stem mounting opening are formed in one side of the meter shell body; the meter shell body is horizontally in threaded connection with the water inlet connecting nut at an angle of 180 degrees, and is also horizontally in threaded connection with the water outlet connecting nut at an angle of 180 degrees; the length of the meter shell is 115mm; and the nominal diameter of the water outlet connecting nut and the nominal diameter of the water inlet connecting nut are DN15-DN25. A one-step injection molding process is performed on the meter shell body. The small-diameter water meter shell is small in size and compact in structure, is not required to be machined, and has high economic benefit and high social benefit. The problems that running water is polluted secondarily due to the fact that rust paint and rust can appear on cast iron meter shell bodies or other non-ferrous metal shell bodies in the existing market can be effectively solved.
Description
Technical field
The present invention relates to
oneplant the small diameter watermeter case made of PPO material.
background technology
Civilian small-bore intelligent IC card water meter in the market, majority is rotor water gauge, and be the card water meter with mechanical count and electronic counting dual-use function, this water meter is because need to provide mechanical data and electronic data, and its inside needs mechanical count structure and electronic counting structure.Wherein mechanical count part requires counter is set, and index dial etc. make water meter size increase undoubtedly, and the restricted and cost of installation environment increases, and especially for part grown-ups and children district, water meter size increases the transformation variation that also can relate to conduit pipeline.
In addition, the nut that the small diameter watermeter case made body that most countries is used and two ends thereof connect all adopts nonferrous materials, comprises stainless steel, copper, cast iron etc.There is following drawback in the water meter of these materials:
1, stainless steel: cost is higher, and be difficult for processing, be not suitable for batch production.
2, copper shell: can cause water pollution once again, hygienic requirements is difficult to reach.And China is the country of a copper resource shortage, the smelting of copper need to expend a large amount of energy, does not conform to the policy of energy-saving and emission-reduction.
3, cast iron: moulding and processing technology are loaded down with trivial details, especially casting pig, its inner preservative treatment difficulty is large, can get rusty, and causes the secondary pollution of water quality.Not only wasted resource but also unhygienic.Ministry of Construction's industry standard " CJ266-2008 potable water cold-water meter safety rule " requires to rise for 2010 the iron-clad water meter of eliminating ash casting material.
China's nonferrous metal resource is rare, how to reduce and reduces the utilization of resources of non-ferrous metal, can ensure again mankind's drinking water hygiene and health requirements, becomes a great problem that new environment Xia Ge water meter manufacturing enterprise faces.
summary of the invention
The object of the invention is to, for the deficiencies in the prior art, provides
oneplant the small diameter watermeter case made of PPO material.
The object of the invention is to be achieved through the following technical solutions:
onethe small diameter watermeter case made of planting PPO material, comprises water delivering orifice attaching nut, watch shell and water inlet attaching nut; Watch shell becomes 180 degree angle levels to be threaded with water delivering orifice attaching nut with water inlet attaching nut; Watch shell is one-body molded, and length is 115mm; And water delivering orifice attaching nut and water inlet attaching nut's nominal bore is DN15-DN25.
Further, a side of described watch shell has sensor installation port and valve rod installing port.
Further, the material of described water meter housing is PPO material.
Further, this watchcase is applicable to electric water meter.
Further, this watchcase is applicable to horizontal and vertical water meter.
The invention has the beneficial effects as follows: this watch shell has solved existing cast iron or other non-ferrous metal watch shells and can produce the problem of rust paint and iron rust pollution tap water.It can ensure that tap water avoids the secondary pollution problem that water supply pipe brings, and owing to having adopted the technique of single injection-molded, volume is little, and compact conformation, does not need to carry out machine work again, has good economic and social benefit.
brief description of the drawings
Fig. 1 is the structural representation of water meter case;
Fig. 2 is the main cut-open view of water meter case;
In figure, water delivering orifice attaching nut 1, watch shell 2, water inlet attaching nut 3, sensor installation port 21, valve rod installing port 22; L=115mm.
Embodiment
The present invention is further illustrated by reference to the accompanying drawings now.
As illustrated in fig. 1 and 2,
onethe small diameter watermeter case made of planting PPO material, the physical dimension of this watchcase and connected mode meet the requirement of relevant national standard to tap water meter.Water meter housing comprises water delivering orifice attaching nut 1, watch shell 2, water inlet attaching nut 3.One side of watch shell 2 has sensor installation port 21 and valve rod installing port 22.1 one-tenth 180 degree angle level of watch shell 2 and water inlet attaching nut 3 and water delivering orifice attaching nut are threaded, and water delivering orifice attaching nut 1 and water inlet attaching nut's 3 nominal bore is DN15-DN25, the length L of described watch shell 2 is 115mm, and the length of the similar water meter housing of conventional same nominal bore is between 165-225mm at present.Therefore water meter housing of the present invention is little with respect to existing water meter volume, and compact conformation does not need to carry out machine work again.
Sensor installation port 21, for water-flow signal sensor is installed, for mounted valve, is realized the control to instrument by valve rod installing port 22.Electronic display unit is installed on watch shell 2.
The material of described water meter housing is PPO material, effectively solves cast iron on existing market or other non-ferrous metal watch shells and can produce rust paint and iron rust and make tap water suffer the problem of secondary pollution.
Small-bore water watchcase of the present invention, is applicable to electric water meter, horizontal and vertical water meter.
