Abstract
The utility model relates to an air bag type dripping metering water meter, comprising the outer shell of the water meter, a water inlet cave, a water inlet pipe connector, a water outlet pipe connector and a water meter core composed of a gear wheel box, an impeller case and a filter screen. The utility model also comprises a steam pocket and an intake pressure switch. The steam pocket is a hermetic steam pocket made of elastic materials. The steam pocket is arranged in the lower part inside the gear wheel box of the water meter core. The intake pressure switch is composed of a guide bushing, a spring, a valve core, a sealing ring gland and a sealing ring. The sealing ring, the sealing ring gland and the guide bushing ordinally contact with the inside of the water inlet pipe connector and are connected with the inner screw of the water inlet pipe connector by the outer screw of the guide bushing. The valve core and the spring are arranged in the guide bushing. The valve core is contacted with the sealing ring under the propulsion of the spring. The surface of the guide bushing is provided with a limber channel. Because the utility model adopts the design approach, dropping water can be measured so long as the present common water meters are partly improved. The utility model has the advantages of simple structure and cheap manufacturing cost.
Description
Technical field:
The utility model relates to a kind of civilian metering water meter, refers in particular to, a kind of steam pocket formula dripping water meter that can realize metering under the state of dripping.
Background technology:
Along with the development of society, people are increasing to the demand consumption of water, have been the work that the whole society all very pays close attention to for water conservation simultaneously.In the user of tap water, exist a small part user to adopt the mode water that drips, because common water meter can not measure, make water supply administrative authority collect water rate by the water consumption of user's reality, not only cause enormous economic loss to country, but also can cause between water supply administrative authority and the user and conflict, bring managerial difficulty for water supply administrative authority.Existing dripping water meter, though can satisfy above-mentioned requirement, but it is to have carried out bigger change by the shell to water meter, set up water storehouse, make the manufacturing of watermeter shell increase difficulty like this, increase the cost of watermeter shell greatly, so not only be unfavorable for the large batch of standardized production of water meter, and increased water user's added burden.
Summary of the invention:
The purpose of this utility model provides a kind of steam pocket formula dripping water meter, to remedy the deficiencies in the prior art.
The utility model is realized as follows: steam pocket formula dripping water meter, the water meter core that it includes watermeter shell, intake antrum, water inlet pipe connector, rising pipe connector and is made of gearcase, impeller box, screen pack, it also includes steam pocket and intake pressure switch; Described steam pocket is the airtight steam pocket that resilient material is made, and it is arranged on the interior bottom of gearcase of water meter core, and described intake pressure switch is arranged in the intake antrum.
Described steam pocket is ring-type or is two semi-ring shapes.
Described intake pressure switch is made up of orienting sleeve, spring, spool, O-ring seal gland and O-ring seal, described O-ring seal, O-ring seal gland and orienting sleeve are pressed on water inlet pipe connector inboard successively, and by the internal thread Joint on external thread on the orienting sleeve and the water inlet pipe connector, in orienting sleeve, be provided with spool and spring, spool offsets with O-ring seal under the thrust of spring, is provided with water-flowing trough on the surface of orienting sleeve.
When the normal water of the water user tap of fetching boiling water, tap water is under the intake pressure effect, and the acting force that overcomes spring promotes spool, and water enters water meter through water-flowing trough and intake antrum and carries out gage work.
When the water user drips, the oppressed steam pocket of water meter in-core begins to expand, water begins to ooze, hydraulic pressure reduces in the watermeter shell, when the total pressure of the acting force of hydraulic pressure in the watermeter shell and spring during less than intake pressure, water inlet promotes spool and opens water inlet switch, and water inlet pours in and drives the metering of dripping of water meter core in the water meter.
A kind of steam pocket formula of the utility model dripping water meter good effect is: owing to adopted present design, improve as long as existing common water meter is carried out part, just can accomplish the metering of dripping, it is simple in structure, and is cheap, is convenient to promote.
Description of drawings:
Fig. 1 is a sectional structure synoptic diagram of the present utility model.
Among the figure, 1 water inlet pipe connector, 2 O-ring seal glands, 3 orienting sleeves, 4 water-flowing troughs, 5 watermeter shells, 6 gearcases, 7 steam pockets, 8 impeller box, 9 rising pipe connectors, 10 screen packs, 11 intake antrums, 12 springs, 13 spools, 14 O-ring seals.
Below in conjunction with accompanying drawing the utility model is described further.
Embodiment:
As shown in the figure, the steam pocket formula dripping water meter that the utility model is related, the water meter core that it includes watermeter shell 5, intake antrum 11, water inlet pipe connector 1, rising pipe connector 9 and is made of gearcase 6, impeller box 8, screen pack 10, it also includes steam pocket 7 and intake pressure switch; The airtight steam pocket 7 that described steam pocket 7 is made for resilient material, it is arranged on the bottom in the gearcase 6 of water meter core, and described intake pressure switch is arranged in the intake antrum 11.
Described steam pocket 7 is ring-type or is two semi-ring shapes.
Described intake pressure switch is made up of orienting sleeve 3, spring 12, spool 13, O-ring seal gland 2 and O-ring seal 14, described O-ring seal 14, O-ring seal gland 2 and orienting sleeve 3 are pressed on water inlet pipe connector 1 inboard successively, and by external thread on the orienting sleeve 3 and the internal thread Joint on the water inlet pipe connector 1, in orienting sleeve 3, be provided with spool 13 and spring 12, spool 13 offsets with O-ring seal 14 under the thrust of spring 12, is provided with water-flowing trough 4 on the surface of orienting sleeve 3.
A kind of embodiment of the present utility model increases the space in the gearcase 6 of existing water meter, by increasing steam pocket 7, after increasing the intake pressure switch, realizes intake antrum 11, this product does not change the design of part in addition of existing common water meter substantially, the versatility of other part and the standardization level height of product, cheap, be convenient to promote.
