Description

A kind of intellectual water meter radio frequency casing clamping body

Technical field

The present invention relates to a kind of water meter cases, and in particular to a kind of intellectual water meter radio frequency casing clamping body.

Background technology

Electronic intelligence water meter is mounted in the adverse circumstances such as kitchen, bathroom, well, open air mostly, and requires the longer longevity Life, therefore integral waterproofing moisture protection is very crucial, especially to the actuator waterproof requirement higher being mounted in housing, once it intakes It can not just use.On the one hand, actuator is often mounted directly in closed chamber, is not subject to other protection, and confined air Between the fixed form of itself do not ensure that good water proofing property, the circulation of water is again extremely strong, so as usage time lengthens, Extremely easily water inlet, is damaged so as to the component of actuator, causes intellectual water meter that can not be continuing in airtight chamber.It is another Aspect, because the information of actuator needs to be transferred to the outside of airtight cavity by signal wire, signal wire has to pass through closed String holes on chamber outer wall, therefore certainly will there are gaps, in the prior art, generally use silica gel between signal wire and chamber outer wall It is sealed with gap of the other manner between signal wire and cavity outer wall body.In the aging action of severe condition and material Under, this sealing structure and mode cannot reach sealing effect reliably and with long-term.

Invention content

In order to overcome the above-mentioned deficiency of existing intellectual water meter housing, the present invention provides a kind of intellectual water meter of good airproof performance and penetrates Frequency casing clamping body.

The present invention the technical solution to solve the technical problem is that：A kind of intellectual water meter radio frequency casing clamping body, including by protecgulum and The housing of back seat composition, the housing is interior to be equipped with lateral partitions, which is divided into the housing to install base The upper chamber of table and the lower chambers for installing actuator assembly, it is recessed that the upper surfaces of the lower chambers on the back seat offers a circle Slot, the lower face of the lower chambers on the protecgulum are equipped with a circle flange, and the flange is buckled into the groove, and described The first sealing ring is equipped between flange and groove；

Bottom chamber on the back seat is equipped with the actuator zones for placing actuator, and the edge of the actuator zones upwardly extends Side wall is formed, the upper end of the side wall is also covered with a upper plate, which is tightly connected by fluid sealant and the side wall；

The first through hole passed through for valve rod is further opened on the bottom surface of the actuator zones, it is close also to be provided with second in the first through hole Seal.

The beneficial effects of the present invention are：By the use of the sealing elements such as sealing ring, cell sealing cap, rubber seal plug, It ensure that good leakproofness, while be provided with actuator zones so that sealing performance of the invention is more remarkable.

Specific embodiment

The present invention is described in further detail with reference to the accompanying drawings and detailed description.

With reference to Fig. 1~Fig. 3, a kind of intellectual water meter radio frequency casing clamping body is described including the housing being made of protecgulum 1 and back seat 2 Housing in be equipped with lateral partitions 3, which is divided into the upper chamber 4 for installing base table by the housing and is used for The lower chambers 5 of actuator assembly are installed, the upper surface of the lower chambers 5 on the back seat 2 offers a circle groove 6, the protecgulum 1 On the lower faces of lower chambers 5 be equipped with a circle flange 7, the flange 7 is buckled into the groove 6, and the flange 7 with The first sealing ring is equipped between groove 6；The actuator zones 8 for placing actuator are equipped in lower chambers 5 on the back seat 2, The edge of the actuator zones 8 upwardly extends to form side wall 9, and the upper end of the side wall 9 is also covered with a upper plate 11, and the upper plate 11 is logical Fluid sealant is crossed to be tightly connected with the side wall 9；Be further opened with passing through for valve rod on the bottom surface of the actuator zones 8 first is led to Hole 10 also is provided with the second sealing ring in the first through hole 10.

The present invention then by actuator assembly loading actuator zones 8, is then covered in use, first base table is fitted into housing Upper plate 11, is sealed with fluid sealant, be performed simultaneously device valve stem part stretch out first through hole 10, and with the second sealing ring into Row sealing, so as to ensure that the leakproofness of actuator zones 8.Then line passed through from string holes and connect with upper chamber 4 inner assembly, Then string holes is clogged with rubber seal plug, and then fastens protecgulum 1 and back seat 2, and the first sealing ring of junction ensures good Leakproofness.

Claims (1)
