Abstract

The utility model discloses a mass flowmeter choke seat, the installation comprises a sleeve, sheathed tube last surface has the controller, the equal fixedly connected with outer tube in sheathed tube both ends, the slot has all been seted up to the outer wall left and right sides of outer tube, the arc groove has been seted up by preceding position in the inner chamber of outer tube, built-in ring is installed by the back position in the inner chamber of outer tube. According to the air nozzle seat of the mass flowmeter, the external connecting pipe is inserted into one end of the sleeve, after the external connecting pipe moves towards the inner cavity of the sleeve, the outer ring connected to the outer wall of the external connecting pipe can contact the position of the built-in ring, and the outer ring at the moment can contact the inner ring of the sealing ring under the extrusion of external force, so that the butt joint position of the sleeve and the external connecting pipe is sealed.

Description

Mass flowmeter air nozzle base

Technical Field

The utility model relates to a trachea field specifically is a mass flow meter air nozzle seat.

Background

The nozzle of gas range has one gas hole with two or more gas holes in different diameters, and the gas hole has partial holes communicated with the air inlet hole for taking in great amount of air to help combustion.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a mass flowmeter air cock seat to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a mass flowmeter choke seat, includes the sleeve pipe, sheathed tube last surface mounting has the controller, the equal fixedly connected with outer tube in sheathed tube both ends, the slot has all been seted up to the outer wall left and right sides of outer tube, the arc groove has been seted up to the inner chamber of outer tube near the front position, the inner chamber of outer tube is installed at the position near the back and is built-in the ring, be provided with the sealing washer between built-in ring and the arc groove, the sealing washer is installed at the inner chamber middle part of outer tube.

As a further aspect of the present invention: an outer pipe is inserted into one end of the outer pipe, an outer ring is installed on the outer wall of the outer pipe close to the front portion, and the outer ring is located in the inner ring of the sealing ring.

As the utility model discloses further scheme again: the flowmeter is installed to the detection end of controller, the notch position of slot is pegged graft and is had the inserted sheet, and the notch of slot is passed through to the one end of inserted sheet to be located the notch position of arc groove.

Compared with the prior art, the beneficial effects of the utility model are that:

this practicality, to take over the outer sheathed tube one end of inserting, take over towards the cover pipe inner chamber displacement back outside, the outer loop of connecting on the outer wall of outer connecting pipe will contact built-in ring position, and the outer loop at this moment under the extrusion of external force, will contact with the inner ring of sealing washer to the realization is managed the sealed at butt joint position with outer sleeve pipe, and its structure is optimized more, the design is more reasonable.
