Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an explosion-proof waist wheel flowmeter based on the steam medium fluid coal-to-gas sleeve, so as to solve the problem that the steam-medium fluid-type coal-to-gas is a commonly used transport material in pipelines and is also a Raw materials for lighting and cooking in household stoves are often transported in coal-to-gas pipelines, and waist wheel flowmeters are often used to measure pipeline pressure. At this time, the internal sliding brush of the buoy plate rubs against the flowmeter connected to the entire pipeline. Sparks, causing the ignition of flammable coal-to-gas contact with sparks, thus causing conflicting operation of mechanical transmission work protection to the waist wheel rotation friction of the flowmeter and buoy collision, resulting in potential safety hazards for equipment, and to the air pressure of coal-to-gas real-time detection is a very difficult problem

Embodiment 1

[0032] see Figure 1-Figure 7, the present invention provides an explosion-proof waist wheel flowmeter based on a steam medium fluid coal-based gas sleeve wheel, the structure of which includes: a short buoy tank 1, a pointer dial 2, a dial frame cover 3, an overflow valve block 4, and a sleeve wheel With a guide tube 5, an overflow recoil cylinder 6, and a flange seat 7, the pulley with a guide tube 5 is nested under the bottom of the short buoy tank 1 and the axes are collinear, and the flange There are two seats 7 and they are respectively inserted and embedded on the left and right sides of the guide tube 5 of the pulley belt. The overflow recoil cylinder 6 is fastened together with the buoy short groove tube 1 through the overflow valve block 4 . The pointer dial 2 is nested together with the dial frame cover 3 and is on the same level. The dial frame cover 3 is installed on the top of the buoy short tank 1, and the overflow recoil cylinder 6 is installed on the buoy shor...

Embodiment 2

[0038] see Figure 1-Figure 7 , the present invention provides a coal gas sleeve explosion-proof waist wheel flowmeter based on steam medium fluid, other aspects are the same as in Embodiment 1, the difference is:

[0039] see image 3 The deflector track 5G is composed of a crawler strip 5G1, a deflector bend 5G2, and a diversion prismatic plate 5G3. The crawler strip 5G1 and the deflector bend 5G2 are inserted into one body and are perpendicular to each other. The plate 5G2 is installed directly above the diversion prismatic plate 5G3 and is on the same vertical plane, and the diversion prismatic plate 5G2 and the diversion prismatic plate 5G3 are respectively erected on the top floor and the bottom floor to ensure the airflow lift of the top floor and the airflow distribution of the bottom floor. The brushing effect ensures the continuity of the air pressure difference between the upper and lower levels, and facilitates the output efficiency of the pipeline connection.

Abstract

The invention discloses an explosion-proof waist wheel flowmeter based on a steam-medium fluid-based coal-gas sleeve. , overflow recoil cylinder, and flange seat. The invention realizes the use of the buoy short groove tube and the sheave belt guide tube to cooperate to avoid mutual friction and use the deflector track to cover the tension and reduce the strong bumping operation , to form a low-friction slow linkage floating plate detection effect, through the airtight inner chamber to the pointer dial on the top, to form a sealing effect, to avoid leakage of coal-based gas to the gear dial due to insufficient air-tightness, and to achieve overall coal-based gas Strict anti-explosion measures, and then form a low-density flow diversion effect according to the characteristics of the steam medium fluid, let the diversion curved plate divert the prismatic plate to form a fluid flow, beat speed up and decelerate two operating effects, and improve the performance of the waist wheel flowmeter Explosion-proof strength, improve the transmission effect of the pulley belt for coal-to-gas.

Description

technical field [0001] The invention is an explosion-proof waist wheel flowmeter based on a steam medium fluid coal gas sleeve, belonging to the field of flow instruments. Background technique [0002] Coal-to-gas is a type of steam medium fluid. It is often called coal gas in people's mouth. It is the raw material for cooking and burning in household stoves. For the pipeline pressure control and transportation of coal-to-gas, waist wheel flowmeter is often used for pipe flange butt joint and dial The index detection display operation, the shortcomings of the current technology to be optimized are: [0003] The coal-to-gas of the steam medium fluid type is a commonly used transport material in pipelines, and it is also the raw material for lighting and cooking in household stoves. In the pipeline transportation of coal-to-gas, waist wheel flowmeters are often used to detect pipeline pressure. At this time, the inside of the buoy plate Sliding brush friction can easily gener...
