Abstract
The utility model relates to an oil-gas recovery joint. The structure comprises a joint seat which is connected with an oil-gas pipeline joint of an oil storage tank in a matching way. Mainly, the interior of the joint seat is provided with a switching device which is composed of a valve seat, a valve clack, a valve rod, a spring and a top cap, wherein the valve seat is provided with a plurality of ventilating holes, and sealed and fixed in the joint seat; the valve clack is fixedly connected to one end of the valve rod, and sealing surface which are matched mutually are arranged between the valve clack and the valve seat; the other end of the valve rod passes through a centre hole of the valve seat and is fixedly connected with the top cap, and the valve rod between the top cap and the valve seat is sheathed with the spring. When the utility model is disassembled from the oil-gas pipeline joint of the oil storage tank, the valve rod can be pulled by the spring force, and thus, the valve clack and the valve seat restore the sealing state. As a consequence, the utility model can prevent the residual gas oil in an oil-gas recovering pipeline from emitting into the air and avoid loss of oil-gas energy source, environment protection pollution and hidden danger of fire safety. The utility model is the joint which is suitable for oil tank vehicles and oil-gas recovering pipelines used for oil filling or oil discharge of oil storage tanks of oil houses.
Description
Technical field
The utility model relates to a kind of pipe coupling, and the oil gas about oil storage tank reclaims joint specifically.The utility model is applicable to that fuel tank and oil depot oil storage tank refuel or the joint on the oil gas recovery channel when draining the oil.
Background technique
Fuel tank and oil depot oil storage tank etc. when refueling, outwards discharging of gaseous state oil in the oil storage tank, and when draining the oil, make-up gas in oil storage tank keeps oil storage tank internal pressure balance.At present, when domestic fuel tank and oil depot oil storage tank refueled, the oil gas in its oil storage tank directly was discharged in the atmosphere, by the replenish air balance that keep-ups pressure in the oil storage tank, caused oil gas loss, environmental pollution and fire safety evaluating hidden danger when draining the oil.External fuel tank and oil depot oil storage tank, its oil storage tank top is provided with pipeline to the oil storage tank bottom, during oiling, connect the oil gas recovery channel at the oil storage tank that is refueled with by between the oil storage tank of draining the oil, make and reach fluid oil and gaseous state oil exchange conveying between two oil storage tanks, realization oil gas reclaims, its shortcoming is: after oiling finishes, the oil gas recovery channel is when the oil and gas pipes joint of oil storage tank unloads, residual gasol can be dispersed in the air in the oil gas recovery channel, still has problems such as oil gas loss, environmental pollution and fire safety evaluating hidden danger.
Summary of the invention
The purpose of this utility model is the problem that exists at prior art, provide a kind of when refueling or draining the oil in the oil storage tank oil gas be not dispersed into fully and remove the oil gas recovery joint of energy-saving and environmental protection, safety in the atmosphere.
The technological scheme that realizes the utility model purpose comprises a connection block that is connected with oil storage tank oil and gas pipes joint, mainly be in connection block, to be provided with switch gear, this switch gear is made up of valve seat, flap, valve rod, spring and top cap, valve seat is shaped on several ventilating holes, be sealingly fastened in the connection block, flap is fixedly connected on an end of valve rod, and be shaped on the sealing surface that cooperatively interacts between the valve seat, the valve rod the other end passes valve base center hole fixedlys connected pocketed springs on the valve rod between top cap and the valve seat with the top cap.
In above technological scheme, between flap and the valve seat by the O-ring seals fitted seal.
In technique scheme, fixedly connected by screw thread between valve seat and the connection block.
The utility model beneficial effect compared with prior art is to be provided with switch gear in connection block, when the utility model and oil storage tank oil and gas pipes joint connect, top cap in its top cap and the oil storage tank oil and gas pipes joint backs down mutually, make spring compression separately, back down flap separately, switch in the oil storage tank oil and gas pipes joint and the switch in the utility model joint are opened simultaneously, and oil gas is flowed to the oil storage tank of draining the oil by the oil storage tank that is refueled by two joints; When the utility model when oil storage tank oil and gas pipes joint unloads, spring ejects the top cap, spring force pulling valve rod makes flap and valve seat recover sealing state, prevents that residual gasol is dispersed in the air in the oil gas recovery channel, avoids oil gas energy loss, environmental pollution and fire safety evaluating hidden danger.
Description of drawings
Fig. 1 is a structure cut-away view of the present utility model.
Embodiment
Oil gas as shown in Figure 1 reclaims joint, comprise a connection block 1 that is connected with oil storage tank oil and gas pipes joint, in connection block 1, be provided with switch gear, this switch gear is made up of valve seat 3, flap 2, valve rod 6, spring 4 and top cap 5, several vents seal that are shaped on valve seat 3 are fixed in the connection block 1, flap 2 is fixedly connected on an end of valve rod 6 by nut 7, and be shaped on the sealing surface that cooperatively interacts between the valve seat 3, valve rod 6 the other ends pass valve seat 3 center holes fixedlys connected pocketed springs 4 on the valve rod 6 between top cap 5 and the valve seat 3 with top cap 5 screw threads.Between flap 2 and the valve seat 3 by the O-ring seals fitted seal.Fixedly connected by snap close 9 or screw thread between valve seat 3 and the connection block 1.Step in the connection block 1 is provided with packing ring 8, and its afterbody is connected with the oil gas recovery channel, and packing ring 8 compresses sealing with the end face of oil storage tank oil and gas pipes joint and contacts.Its working procedure is: during oiling, oil gas recovery channel joint docks mutually with oil storage tank oil and gas pipes joint, packing ring on the end face of oil storage tank oil and gas pipes joint and the oil gas recovery channel joint step compresses sealing, switch gear in two joints has same structure, after the butt joint of two joints, the top cap of two switch gears backs down flap mutually, opens switch separately, and oil gas flows to the oil storage tank of draining the oil from the oil storage tank that is refueled; When finish refueling, after two joints separated, the flap of two joint switch gears was recovered sealing state by spring tension and valve seat, prevented from that oil gas is external to let out.
