Abstract

The utility model discloses a full interception device, which is arranged between the inner wall of a water pipe and the outer wall of a flow meter. The full interception device comprises a full interception frame, an inflation bag and an inflation pipeline. The full interception frame is sleeved on the outer wall of the flow meter in a sealing manner, the inflation bag is fixedly sleeved on the full interception frame in a sealing manner, one end of the inflation pipeline is communicated with the inflation bag in a sealing manner, the other end extends out of the water pipe, and the outer surface of the inflation bag is attached onto the inner wall face of the water pipe in a sealing manner after inflation. The full interception device has fine interception effect, leads water to completely flow to a water outlet through the flow meter, realizes complete water interception, has simple structure, is reliable and novel, and is accurate in calibration result.

Description

Full cut-off equipment

Technical field

The utility model relates to a kind of full cut-off equipment.

Background technology

As shown in Figure 1, be existing cut-off equipment, during work, water enters water pipe 1 ' from water inlet, and under the effect of damming of current collecting umbrella A, most water pass through from flowmeter 2 ', flow out from rising pipe 11 ', because current collecting umbrella A and water pipe 1 ' inwall are not absolute sealings, so fraction water flows through from current collecting umbrella A, again from rising pipe 11 ' outflow.Just there is error in the reading of flowmeter 2 ' like this, although can calibrate discharge by water pipe more accurately by alternate manner, but still can have the flow meter calibration error.In order to calibrate discharge very accurately, my company develops the full cut-off equipment of a cover.

The utility model content

The purpose of this utility model be provide in order to solve the problems of the technologies described above a kind of simple in structure, current are all passed through from flowmeter, thereby calibrate the full cut-off equipment of discharge very accurately.

To achieve these goals, the utility model is by the following technical solutions:

A kind of full cut-off equipment, it is arranged between pipe inner wall and the flowmeter outer wall, it comprises: the skeleton that dams entirely, gas cell and loading line, this reinforced seal of damming entirely is solidly set on the outer wall of described flowmeter, this gas cell sealing is solidly set on the skeleton that dams entirely, this loading line one end is communicated with this gas cell sealing, and its other end stretches out described water pipe, and this its outside surface sealing of gas cell inflation back fits in described pipe inner wall face.

The described skeleton that dams entirely comprises bracing frame, two clamp nuts and two O-ring seals, this bracing frame roughly is dumbbell shaped, be the thick middle thin body in two ends, this clamp nut is installed in respectively in the two butt end inwalls and the ring groove between the described flowmeter outer wall of this bracing frame, the sealing snare is located on the described flowmeter outer wall and is positioned at this ring groove bottom, fixes simultaneously between described flowmeter, support frame as described above and described clamp nut.

In the described skeleton upper end of damming entirely one fixation clamp is set.

The beneficial effects of the utility model: the resulting full cut-off equipment of the utility model, it dams effective, makes water flow to water delivering orifice by flowmeter fully, and its realization the whole of water dam, and the result is simple, and is reliable, novelty, calibration result is accurate.

Embodiment

A kind of full cut-off equipment, it is arranged between pipe inner wall and the flowmeter outer wall, and it comprises: the skeleton that dams entirely, gas cell and loading line.This reinforced seal of damming entirely is solidly set on the outer wall of described flowmeter, this gas cell sealing is solidly set on the skeleton that dams entirely, this loading line one end is communicated with this gas cell sealing, and its other end stretches out described water pipe, and this its outside surface sealing of gas cell inflation back fits in described pipe inner wall face.

As shown in Figures 2 and 3, be better embodiment of the present utility model, in actual applications, flowmeter 2 is fixed in the water pipe 1.One full cut-off equipment 3 is set between water pipe 1 inwall and flowmeter 2 outer walls.Cut-off equipment 3 comprises the skeleton 31 that dams entirely, gas cell 32 and loading line 33.The skeleton 31 that dams entirely comprises bracing frame 311, two clamp nuts 312 and two O-ring seals 313.Bracing frame 311 is the thick middle thin body in two ends for roughly being dumbbell shaped.Bracing frame 311 is enclosed within on the outer wall of flowmeter 2, the inboard wall of tube body and the flowmeter outer wall of 311 liang of butt ends of bracing frame leave ring groove, O-ring seal 313 is fixed in the bottom that is positioned at ring groove on flowmeter 2 outer walls, clamp nut 312 is installed in this ring groove, and O-ring seal 313 closely fixes between flowmeter 2, bracing frame 311 and clamp nut 312.The two ends of gas cell 32 make its sealing be solidly set on two butt ends of bracing frame 311 by gas cell clamp 34.The butt end of one end hermetically passing bracing frame of loading line 33 and gas cell 32 internal communication, its other end stretches out water pipe 1.Gas cell 32 inflation back outside surface sealings fit in water pipe 1 inwall, and anti-sealing flows directly into the water pipe water delivering orifice through the gap of gas cell and pipe inner wall.The skeleton that dams entirely for knowing clearly is stabilized on the flowmeter 2, when preventing that water flow pressure is big, and the skeleton play on flowmeter that dams entirely, the skeleton upper end is provided with a fixation clamp 4 damming entirely.

The resulting full cut-off equipment of the utility model, a whole set of throttle full open device is sleeved on the flowmeter outside, tighten clamp nut, flatten O-ring seal, the clearance seal that make gas cell, dams between skeleton and the flowmeter entirely is waterproof, and relies on friction force between O-ring seal and the flowmeter to make full cut-off equipment relative fixed, considers simultaneously when hydraulic pressure is very big, in order to make full cut-off equipment fixation, above the skeleton that dams entirely, install a fixation clamp additional.Give gas cell the sufficient enough gas of pressure by loading line, gas cell is contacted with the pipe inner wall sealing, make water all by flowmeter like this, flow out from rising pipe, flowmeter is the flow of very accurate demarcation water outlet just.

More than be preferred embodiment of the present utility model and design graphic; above-mentioned preferred embodiment and designing graphicly only illustrates; be not to be used to limit interest field of the present utility model; all with equalization technological means or be the interest field that contained of the application's claim and the implementer does not all break away from protection domain of the present utility model.
