Description

A kind of PE ball valves blow device

Technical field

The invention belongs to valve field more particularly to a kind of PE ball valves blow devices.

Background technology

With a large amount of uses of PE (polyethylene) pipelines in fuel gas transmission pipe network, the demand of PE ball valves increasingly increases, PE ball valves compared with conventional metals valve, have it is light-weight, corrosion-resistant, non-maintaining, open and close torque, be small, taking up an area the spies such as few Point, and because with PE tubing material matchings, therefore it is easy for installation, it is wide with PE Gas Pipes in pipeline network of fuel gas in city using simple It is general use and it is more and more common.Since PE ball valve cores are mutually closed with valve body, good keying effect could be realized, so PE Ball valve core itself is required to be smooth and cannot have gap between valve body.But it when line clear, diffusion mouth suppress pressure release, deposits Valve inner is fallen in tiny hard object；There are other tiny hard objects or combustion gas are solidifying for a long time inside pipeline in actual use The particulate matter of knot.If being collected, being cleared up to above-mentioned particulate matter and tiny hard object not in time, particulate matter and tiny may result in Hard object, which scratches ball surface, causes ball surface is rough internal leakage occur, and in the sealing ring combined closely with PE ball valve cores The seal of PE ball valves can be largely effected on by being caught in particulate matter then, and if things go on like this PE ball valves will thoroughly be scrapped, these factors are serious The normal operation for affecting gas ductwork increases the operation cost of gas enterprise.

For example publication number：A kind of PE ball valves for gas ductwork disclosed in 104180009A, internal valve ball is just It is the leakproofness opened and closed come realization device using the close contact between sealing ring；Also publication number：203571094U institutes are public A kind of PE ball valves with pillar opened, also failing to propose to solve the tiny hard object of channel interior influences to scratch ball surface or damage The technical solution of bad sealing ring.Stock trick art solves or weaken PE ball valves, and negative factor is extremely urgent in actual use.

Invention content

Ball surface can be scratched purpose of the present invention is to being directed to tiny hard object in existing PE ball valves pipe to cause internal leakage and carry For a kind of PE ball valves blow device.

The present invention is achieved by the following technical solution：

A kind of PE ball valves blow device includes the stub (tube) being connect with PE ball valve bodies, the stub (tube) intracavity bottom Further include the sweep-up pipe inside the sensible storage capsule in bottom, dust suction equipped with the storage capsule for storing tiny hard object to lower recess Pipe runs through stub (tube), and sweep-up pipe is communicated with dust exhaust apparatus.

PE ball valve bodies upper end is fixed with protecting pipe.

It is equipped on the stub (tube) above storage capsule protruding upward in the banj connectivity port of stub (tube) setting, suction Dirt pipe is stretched to from banj connectivity port in storage capsule.

Banj connectivity port upper end connects desorption tube, and the combination between banj connectivity port and desorption tube Position is arranged electro-fusion sleeve, and the banj connectivity port is connect with desorption tube electric smelting.

The desorption tube upper end connects diffusion valve, and the binding site between desorption tube and diffusion valve is arranged electro-fusion sleeve, institute Desorption tube is stated to connect with diffusion valve electric smelting.

The sweep-up pipe is inserted into after banj connectivity port, desorption tube and diffusion valve are tightly connected and is formed by pipeline Interior, the dust suction bottom of the tube is gone directly inside storage capsule, and dust suction infratubal port is provided with angle.

Clamping plate is provided in the middle part of the desorption tube between the protecting pipe of PE ball valve bodies upper end, the clamping plate is two pieces, It is used in combination screw to be fixed to each other.

The storage capsule may be provided on the stub (tube) of the arbitrary one or both sides of PE ball valve bodies.

The sweep-up pipe top is the bend pipe with angle of inclination.

The dust exhaust apparatus includes the bifurcated pipe for being connected to bend pipe upper end, and the bifurcated pipe bottom side is air intake vent, inlet air Mouth connection wind turbine, bifurcated pipe are connected to bend pipe binding site, and the port of its binding site is dust mouth.

Operation principle：

1：When being not inserted into sweep-up pipe, device can be used as and diffuse use, you can be realized with being opened and closed using diffusion valve It gives out of gas, to the combustion gas pressure release in the pipeline of stub (tube) connection.

2：When opening diffusion valve, it is inserted into sweep-up pipe, the angle of sweep-up pipe bottom end is inserted into storage capsule, at air intake vent External wind turbine, the gas blown out using wind turbine flow through dust mouth, and the particulate matter in storage capsule is sucked out the draught head of generation.

Beneficial effects of the present invention：The present invention has passed on the original advantage of PE ball valves, and is greatly reduced because of channel interior Tiny hard object scratch ball surface or damage the possibility of sealing ring, reduce because in actual installation process, pipeline purging diffuses Mouth suppresses tiny hard object when pressure release and is conducive to concentrate, settles sundries in pipeline and cleared up by valve inner.
