Abstract
The utility model discloses a pipeline pump exhaust valve which comprises a valve seat and a valve stem; wherein the valve and a pump body are connected by threads; the valve seat is provided with an airway, the air inlet of which is communicated with the pump body; the upper of the valve seat is threaded connected to a rotating button; the rotating button is provided with a valve pin corresponding to the valve cone airway; the valve pin contacts the vent in upper side wall of the valve stem. By adopting the pipeline pump exhaust valve, the valve stem rather than the valve seat is required to load down when repair and maintain, so as to avoid damage the pipeline pump caused by frequent loading and prevent the pipeline pump from damage, save time and effort ; increase work efficiency; reduce fuel losses; guarantee workplace safety.
Description
Technical field
The utility model belongs to a kind of pipeline mounted pump outlet valve.
Background technique
Pipeline mounted pump is in carrying lightweight oil plant process, because the evaporation characteristic of oil plant, accumulated gas very easily in the pipeline mounted pump makes it and can not run well, and influences carrying out smoothly of oil plant transmitting-receiving work.At present, the exhaust port of piping for tank farm pump is blocked by the cock-type plug, when pipeline mounted pump needs exhaust, earlier the cock plug is unscrewed dismounting, treat that gas in the pipeline mounted pump is discharged after, plug is screwed in tighten again.Do like this, the one, because plug is tightened in dismounting repeatedly, very easily damage the pipeline pump housing, cause economic loss.The 2nd, drip the oil plant, the oily vapours that emit and accumulate in the operational site, the combustion explosion accident easily takes place.The 3rd, to waste time and energy, operation, exhaust velocity is slow, inefficiency.
Summary of the invention
The purpose of this utility model provides a kind of convenient disassembly, and the protection pipeline mounted pump is not damaged, and reduces the pipeline mounted pump outlet valve of oil loss.
For achieving the above object, solution of the present utility model is: a kind of pipeline mounted pump outlet valve, form by valve seat and valve rod, the described valve seat pump housing is threaded, be provided with air flue in the above-mentioned valve seat, the suction port of air flue is communicated with the pump housing, the described valve seat top valve rod that has been threaded, be provided with air flue in the described valve rod, valve seat is communicated with the air flue of valve rod, the valve rod top turn-knob that has been threaded, described knob is provided with the needle that cooperates with valve rod taper gas port, and described needle cooperates with exhaust port on being located at the valve rod upper portion side wall and contacts.
Adopt above-mentioned pipeline mounted pump outlet valve, because outlet valve is provided with valve seat, valve seat is connected for the silk mouth with the pump housing, and exhaust only need unscrew turn-knob just can finish exhaust process.Maintenance, maintenance only need be unloaded lower valve rod and need not be dismantled valve seat, prevent repeatedly the relief surface damage pipeline pump housing, and the protection pipeline mounted pump is not damaged; If when producing gas, only need a people unscrew the outlet valve turn-knob gently in the pipeline mounted pump, in eight seconds, just can finish exhaust process, time saving and energy savingly increase work efficiency more than 30 times; Because it is swift to operate that outlet valve has, easily characteristics such as control in exhaust process, can only discharge oil gas, and oil plant are difficult for outside the excavationg pump, prevent from that oil plant from dripping to emit, and have improved the safety coefficient of operational site, reduce oil loss, assurance operational site safety.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
As shown in Figure 1, this pipeline mounted pump outlet valve, form by valve seat and valve rod, described valve seat 1 pump housing is threaded, valve seat 1 is made by Cuprum alloy, be provided with air flue in the above-mentioned valve seat 1, the suction port 5 of air flue is communicated with the pump housing, the described valve seat 1 top valve rod 2 that has been threaded, be provided with air flue in the described valve rod 2, valve seat 1 is communicated with the air flue of valve rod 2, the valve rod 2 tops turn-knob 4 that has been threaded, described knob 4 is provided with the needle that cooperates with valve rod 2 taper gas ports, and described needle cooperates with exhaust port 3 on being located at valve rod 2 upper portion side wall and contacts.
During use; gas because of taking place in pipeline mounted pump; and when occurring that work is undesired maybe can not work; with hand inhour rotating exhaust valve turn-knob 4, treat that oily vapours arrange by exhaust port 3 in the pipeline mounted pump, and when the discharge of minute quantity oil plant is arranged; turn-knob 4 again turns clockwise; till tightening, at this moment exhaust port 3 is closed, and finishes exhaust process.Make pipeline mounted pump recover normal.
