Abstract
The utility model discloses an on-line transfer device for leakage of a pressure valve. The on-line transfer device for the leakage of the pressure valve comprises a bolt used for fixedly connecting a valve body and a flange. A drain hole is formed in one end of the bolt in the axial direction. A communication hole communicated to the bottom of an axle hole is formed in the longitudinal direction of the bolt. An outlet of the drain hole is connected with a low-pressure discharge system through a pipeline. A switch-off valve is arranged on the pipeline. The on-line transfer device for the leakage of the pressure valve is simple in structure and convenient to operate. When the valve leaks, leaked gas/liquid inside the valve is transferred to the low-pressure discharge system through the communication hole and the drain hole formed in the bolt under the situation of not affecting normal production or stopping conveying of products, potential safety hazards caused when the valve leaks are eliminated, risk is lowered to the minimum, continuous production is guaranteed and economic benefits are high.
Description
Technical field
The utility model relates to valve and reveals the transfer techniques field, especially a kind ofly can not stop carrying, the transfer device of discharging that valve is revealed online with pressure.
Background technique
In the course of conveying of pipeline, valve plays very crucial effect, and, due to reasons such as the abrasion and corrosion of the wearing and tearing of valve switch, media flow, impurity extruding, the sealing surface of valve can form the damages such as hole falls into, cut, spot, the problem that valve is revealed occurs.When valve generation gas or leak of liquid, can cause transmission medium to run off, cause environmental pollution, cause fault in production (being forbidden as leakage can cause the composition of chemical products); Sometimes also easily trigger major accident disaster (as leaking of safety valve may cause blast, cause the leakage of toxic gas etc.).
The approach that solves at present valve leak mainly contains following two kinds: the one, change valve, and the 2nd, repair valve.Although can solve the problem that valve is revealed, changing valve or repairing valve all needs to stop production and could process, and the maintain and replace time is long and working strength is large, causes unnecessary economic loss.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, a kind of simple in structure, safe and reliable transfer device of revealing with pressure valve online is provided, this transfer device can be in the situation that do not affect normal production, do not stop carrying, the gas/liquid that valve internal is leaked outside by this device online the low pressure releasing system of transferring to pressure discharged.
To achieve these goals, the technical solution adopted in the utility model is: a kind of transfer device of revealing with pressure valve online, comprise for being fixedly connected with the bolt of valve body and flange, it is characterized in that: described bolt one end offers a drain boles in the axial direction, bolt vertically on offer the intercommunicating pore of a connection axis hole bottom, connect the low pressure releasing system by pipeline in the outlet of drain boles, be provided with a shut-off valve on pipeline.
One pipe joint is installed in the outlet of described drain boles, and pipe joint is threaded connection with outlet and the pipeline of drain boles respectively.
The length of described drain boles is 1/4th to 1/2nd of described bolt length; Described intercommunicating pore is positioned at 1/3rd places of bolt.
The beneficial effects of the utility model: simple in structure, easy to operate.While occurring that valve is revealed, in the situation that do not affect normal production, do not stop product and carry, the gas/liquid that valve internal is leaked is transferred to the low pressure releasing system by the intercommunicating pore and the drain boles that are opened on bolt, eliminate the potential safety hazard that valve leak causes, risk is reduced to minimum, for producing and provide safeguard continuously, economic benefit is high.
The accompanying drawing explanation
Fig. 1 is existing valvular structural representation.
Fig. 2 is structural representation of the present utility model.
The structural representation that Fig. 3 is bolt in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Figure 1-3, a kind of transfer device of revealing with pressure valve online of the utility model, comprise that bolt is provided with set screw nut 4 for being fixedly connected with the bolt 3 of valve body 1 and flange 2.Bolt 3 one ends offer a drain boles 31 in the axial direction; Bolt vertically on offer intercommunicating pore 32, intercommunicating pore 32 is connected bottom drain boles.Connect low pressure releasing system 6 by pipeline 5 in the outlet of drain boles 31, be provided with shut-off valve 7 on pipeline 4.
In the present embodiment, a pipe joint 8 is installed in the outlet of above-mentioned drain boles, pipe joint 8 is threaded connection with outlet and the pipeline 4 of drain boles 31 respectively, so, has easy accessibility, and the advantage of good sealing effect.
The length of above-mentioned drain boles 31 is 1/4th to 1/2nd of bolt 3 length; Intercommunicating pore is positioned at 1/3rd places of bolt.On this position, can guarantee that the gas/liquid of valve leakage can be discharged by the utility model.
Working principle of the present utility model is: the gas/liquid leaked outside of valve internal flows to the bolt mounting holes of valve flanges by valve body 1 and the gap of valve flanges 2, the gas/liquid leaked outside is passed to drain boles 31 through being communicated with pore 32, then by pipe joint 5, shut-off valve 6 and the pipeline that is arranged on drain boles 31 outlets, is discharged into the low pressure releasing system 7 of plant area.
Finally should be noted that; above content is only in order to illustrate the technical solution of the utility model; but not to the restriction of the utility model protection domain; the simple modification that those of ordinary skill in the art carries out the technical solution of the utility model or be equal to replacement, all do not break away from essence and the scope of technical solutions of the utility model.
Claims (4)
