Abstract
The utility model relates to an divided compound diaphragm flake and capsule pressure gauge for measuring methane pressure, including a shell, a gauge cover equipped on the shell, a dial plate and indicating needle equipped in the gauge cover and shell, a gauge core equipped in the shell driving the indicating needle for rotation and an input medium connector equipped in the shell. The pressure diaphragm flake is connected with a round connector groove plate by a pressure fixation ring and forms a sealed gas cell with the connector groove plate. The transmission part of the gauge core is equipped on the pressure diaphragm flake, reducing additional parts and the manufacture cost of the gauge to the utmost extent, compared with the existing diaphragm flake device and diaphragm capsule device. The utility model has the advantages of high precision, durability, practicality and reliable performance, applicable to engineering plastics moulding process and mass production, providing with a pressure instrument with high cost performance for rural methane.
Description
Technical field
The utility model belongs to the pressure measurement technology field, relates in particular to a kind of split combined membrane capsule pressure gauge of measuring at biogas pressure, also can be fit to the measurement of other field minute-pressure pressure.
Background technology
The tensimeter volume that initial stage is applied to the measurement of minute-pressure hydrodynamic pressure is generally bigger, people are to the measurement of biogas pressure, adopt U type glass tubular type the earliest, the water column type liquid level gauge, its shortcoming is that the value of reading is not directly perceived, volume is big, broken easily, the inconvenience transportation is installed, a kind of rubber membrane type biogas pressure table had appearred on market afterwards, though it is convenient directly perceived, but this meter accuracy is extremely low, can't satisfy the basic demand that the biogas industry is measured biogas pressure at all, metal film boxlike biogas pressure table appears again on the market thereafter, though this class instrument increases precision, but this type of instrument complex process, complex structure, the production difficulty is big, connecting portion is many, very easily gas leakage, obstruction is difficult to sealing and poor reliability, and the rural market presses for a kind of measuring accuracy height, long service life, simple and reliable, the biogas pressure table that price is low.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of accomplish split combined membrane capsule pressure gauge simple in structure, reliability and durability, with low cost when guaranteeing precision height, long service life, stable performance.
The utility model solves technical scheme that its technical matters adopts: comprise housing, be installed in watch glasses on the housing, be installed in dial plate and pointer in watch glasses and the housing, be installed in the housing and drive the watch core that pointer rotates, the joint of input media is installed in housing, pressure-sensitive diaphragm is sealedly connected on the circular joint frid of joint by pressing solidly ring, pressure-sensitive diaphragm and joint frid form the air chamber of a sealing, and the drive disk assembly of watch core is arranged on the pressure-sensitive diaphragm.
The input end of joint passes the hole that the housing side has and is packed in this hole, and the joint base plate is fixed on housing bottom by screw.The input end of joint also can pass the tapping at the bottom of the shell and be packed in this Kong Zhongzuo and axially install.
Be installed in the housing and drive watch core mounting structure that pointer rotates and be meant that watch core is packed in and press solidly on the ring pillar.Can be meant that also watch core is packed on the inwall of housing.
It is integral structure that dial plate and zero-bit retaining pin and position, end retaining pin adopt the engineering plastics one-shot forming, and dial scale adopts new label printing to paste.Housing, watch glasses adopt the assembling form of concavo-convex buckle.
The beneficial effects of the utility model are: compare with existing various diaphragm instrument, bellows instrument, the utility model has reduced parts to greatest extent, reduced the manufacturing cost of instrument to greatest extent, have degree of accuracy height, simple in structure, durable in use, economical and practical advantage, especially adopt the engineering plastics moulding process, produce in enormous quantities, for the production and use of marsh gas provides a kind of cost performance high pressure instrumentation.

Embodiment
Shown in Fig. 1,2,3,4,5,6, the utility model comprises housing 1, be installed in watch glasses 2 on the housing 1, be installed in dial plate 4 and pointer 3 in watch glasses and the housing, be installed in the housing 1 and drive the watch core 5 that pointer rotates, the joint 9 of input media is installed in housing, pressure-sensitive diaphragm 6 is sealedly connected on the circular joint frid of joint 9 by pressing solidly ring 7, pressure-sensitive diaphragm 6 and joint frid form the air chamber of a sealing, and the drive disk assembly of watch core 5 is arranged on the pressure-sensitive diaphragm 6.The induction pressure measurement drive link that is watch core 5 contacts with pressure-sensitive diaphragm 6.Be provided with hook 8 in housing 1 outside.
The input end of joint 9 passes the hole that the housing side has and is packed in this hole, and the joint base plate is fixed on housing bottom by screw.When instrument axis when installing, the input end of joint 9 can pass the tapping at the bottom of the shell and be packed in this hole, on promptly input end is arranged at the bottom of the shell.
Be installed in the housing 1 and drive watch core 5 that pointer rotates and be meant that watch core 5 is packed in and press solidly on ring 7 pillars.After meeting the demands, casing rigidity also watch core can be packed on the inwall of housing 1.
As shown in Figure 6, housing 1 of the present utility model, watch glasses 2 adopt the assembling form of concavo-convex buckle, and transparent watch glasses 2 promptly of the present utility model is stuck on the housing 1, has avoided becoming flexible the cover phenomenon, and is attractive in appearance firm.Dial plate 4 Pictest covers 2 are installed in the housing 1, and it is integral structure that dial plate 4 adopts the engineering plastics one-shot forming with zero-bit retaining pin and position, end retaining pin, and dial scale adopts new label printing to paste.
As shown in the figure, the utility model is provided with joint 9 in housing, by pressing solidly ring 7 pressure-sensitive diaphragm 6 is sealed and is connected on the circular joint frid, make pressure-sensitive diaphragm 6 and joint frid form an airtight air chamber, after the check sealing is not leaked, the input end of joint 9 is passed the hole that housing one side has and be packed in this hole, the other end is fixed on the base plate on the housing by screw, afterwards the watch core 5 of pressure drive mechanism is packed in and presses solidly on the ring 7, joint 9, pressure-sensitive diaphragm 6 and watch core 5 connect into a firm integral body, form a complete pressure survey transmission system, when the input end of measured medium by joint 9 enters by the airtight air chamber that is composited that is connected of pressure-sensitive diaphragm 6 and joint frid, pressure lifting makes diaphragm produce displacement, and drives pointer 3 rotations by transmission watch core 5, indicates corresponding force value.
