Description
Technical field
The utility model relates to a kind of fluid valve, relates in particular to a kind of shutoff check fluid valve.
Background technique
On the pipeline of conveyance fluid, often need some fluid valves are installed, be used to realize shutoff to the pipeline inner fluid.Sometimes in order to realize the safe operation of fluid in the pipeline, also need to install additional an one-way valve in pipeline, when the fluid in the pipeline reverse flow occurred because of abnormal conditions, this one-way valve can be closed under the effect of the reverse Driving force of fluid.Existing two kinds of above-mentioned fluid valves generally separate, and they are serially connected on the pipeline.Two kinds of fluid valves when realizing with the pipeline assembling, troublesome poeration, and in circulation and transportation process, need to take great amount of manpower and material resources.
The model utility content
The purpose of this utility model is at the problems referred to above, provide a kind of simple and compact for structure, be convenient to the shutoff check fluid valve with pipeline assembling, circulation and convenient transportation.
The purpose of this utility model can realize by following technical proposal: a kind of shutoff check fluid valve, comprise valve body, valve gap, be connected in the valve rod on the valve gap, the outside of valve gap is stretched out in the outer end of valve rod, the inner is positioned at valve body, the inner of valve rod is provided with the valve head that is used to close fluid, it is characterized in that for flexibly connecting, valve head can slide towards the direction that breaks away from valve rod between described valve head and the valve rod under the effect of fluid.This fluid valve is integrated common fluid valve and one-way valve, and it had both had the turn-off function of convection cell, has the function that prevents the fluid reverse flow again.After this fluid valve is assemblied in the pipeline, can realize the through and off of fluid in the pipeline by operating valve lever.After this fluid valve is opened, fluid can flow from the gap location between valve head and the valve body, when abnormal conditions and reverse flow appear in fluid in the pipeline mobile, fluid oppositely promotes valve head, valve head slides on valve rod and fits together with valve inner, thereby the reverse flow of block fluid has improved the Security of fluid in the pipeline.
In this shutoff check fluid valve, described valve head is provided with the fittings body of tubular, inserts in this fittings body to the gap of inner end of described valve rod.
In this shutoff check fluid valve, be with pressure spring on the inner of described valve rod, the two ends of this pressure spring link with the interior edge face and the valve head of described valve gap respectively.
In this shutoff check fluid valve, the interior edge face of described valve gap is provided with the boss of a ring-type, and described valve rod passes this boss, and an end of described spring is socketed on this boss.
In this shutoff check fluid valve, establish the sealing gasket of a ring-type on the described valve head end face relative, on valve body, be provided with the bulge loop of a ring-type, but sealing pad roof pressure is on the end face of described bulge loop with the corresponding position of described sealing gasket with valve rod.
In this shutoff check fluid valve, on described fittings body, be provided with open-work.
In this shutoff check fluid valve, described valve gap is provided with the tubular convex body that is connected as a single entity with it, described valve rod passes this convex body, between valve rod and convex body, be provided with several circular fillers, the inboard of filler is socketed with a filler pad on valve rod, and the outside screw of filler is connected with a filler screw.
Compared with prior art, the beneficial effects of the utility model are:
1, this fluid valve has been integrated the function of existing common fluid valve and one-way valve, and is simple and compact for structure.
2, only this fluid valve need be set on the pipeline of conveyance fluid, just can realize that the shutoff of fluid is non-return in the pipeline, assembling is simple, the construction cost that helps saving pipeline.
3, owing in fluid circuit, do not need to install one-way valve, make things convenient for the circulation of this fluid valve, be convenient to save transport power.
