Technical Field

The invention belongs to the technical field of ultrasonic gas meter base structures, and particularly relates to an ultrasonic gas meter base for preventing gas stealing.

Technical Field

At present, the ultrasonic gas meter on the market is characterized in that a metering module is transversely arranged and then connected with an aluminum drainage tube (as shown in figure 1). The disadvantages of this solution are 1. the manufacturing cost of the drainage tube is high; 2. solid particles can be deposited in the metering module after entering the metering module, so that the metering effect is influenced, and the service life of the meter is shortened; 3. the user can realize stealing gas and stealing gas through the mode of destroying the drainage tube when using, when causing the loss to the air feed company, also causes the risk to the use place.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides an ultrasonic gas meter base meter capable of preventing gas stealing.

An ultrasonic gas meter base meter capable of preventing gas stealing comprises a front steel shell, a mesh enclosure, a drainage tube, a metering module, a rear steel shell, a valve and a high-temperature wiring terminal.

The front steel shell comprises an air outlet meter connector, a connecting plate, a front steel shell body and an air inlet meter connector, the mesh enclosure is placed inside the air outlet meter connector, the metering module is vertically placed, the possibility that solid particles enter the metering module and are deposited inside the metering module is reduced, the drainage tube is installed on the front steel shell through the connecting plate, one end of the drainage tube is axially fixed with the air outlet meter connector, the other end of the drainage tube is connected with the metering module, and the valve is installed on the front steel shell through the connecting plate and is axially fixed with the air outlet meter connector; the high-temperature wiring terminal is installed on the front steel shell, the lead wires on the metering module and the valve are connected with the inner side of the high-temperature wiring terminal, the external interface of the high-temperature wiring terminal is connected with the external main control board in a wiring mode, and the rear steel shell is in butt joint with the front steel shell to form a complete ultrasonic gas meter base meter.

Furthermore, the mesh enclosure adopts a bending structure.

Furthermore, the mesh enclosure is made of stainless steel.

Furthermore, the drainage tube is fixed with the metering module through a bolt.

Furthermore, the connecting plate on be provided with screw hole and buckle, preceding box hat casing has seted up the through-hole.

Furthermore, the drainage tube passes through, and the high temperature terminal adopts the form of riveting to be connected with preceding box hat through the through-hole that the preceding box hat casing was seted up.

Furthermore, the rear steel shell and the front steel shell are fixed through an additional stainless steel wrapping ring.

The invention has the following beneficial effects:

on traditional ultrasonic wave gas table structure basis, optimized the overall arrangement and the design of inside accessories, the measurement module of original horizontal putting is vertical to place to this optimizes the drainage tube structure, has reduced manufacturing cost, and reduced solid particle and got into the measurement module and in the sedimentary possibility in inside. Place a stainless steel screen panel in table joint gas outlet department, make the user can't accurately observe basic table inner structure when wanting to destroy the drainage tube to the hardness of stainless steel material also can prevent effectively that it from using common instruments such as flatiron, electric drill to carry out the violence destruction. The bending structure can protect the gas meter and reduce the gas pressure loss of the meter when in use. The scheme has the advantages of cost saving, solid particle pollution resistance, gas theft prevention and small gas pressure loss.
