Description
Technical field
The utility model is related to a kind of valve, especially a kind of check-valves.
Background technology
Check-valves is automatically closed and seals by pressure medium realization, is mainly used for preventing medium from flowing backwards, and protects in pipeline
Pump and other key equipments, the check-valves used in the prior art is external to pressing from both sides check-valves, for the ease of assembling,
It needs, in valve body side auger shell pit, to add potential leakage point；And there are thread failure risk, especially to high temperature and high pressure condition
In use, there are huge security risks.
Utility model content
In order to solve the shortcomings of the prior art, the utility model provides a kind of few interior of compact-sized, leakage point
Formula is put to pressing from both sides single-lobe check-valves.
A kind of built-in type opposite clip single-lobe check-valves in the utility model, including valve body, valve shaft, flap and torsional spring；Valve body
Middle part is medium runner, and medium runner right side is medium inlet, left side is media outlet, and medium runner is included from right to left successively
The diversion section that is equipped with, middle part and outflow section, diversion section are right wide left narrow flared structure, middle part be and diversion section on the left of
Equal diameter, concentric cylinder, the concentric cylinder of outflow Duan Weiyu middle parts, outflow section diameter are more than middle part diameter；Valve
Valve main body is the U-shaped revolving structure in section, and flap top is equipped with ear's structure for installation；Flap is rotatable by valve shaft
Mounted on outflow section and middle part stage portion, flap can cover middle part, on valve shaft on the outside of flap between outflow section inner wall
Equipped with torsional spring, torsional spring is used to that flap to be made to be bonded with outflow section and middle part stage portion, cover middle part.By pressure medium, bullet
Spring active force and the realization of flap self gravitation are automatically closed and seal, and are mainly used for preventing medium from flowing backwards, protect the pump in pipeline
And key equipment, whole built-in, without the leak source that leaks, compact in structure and convenient to use, maintenance cost is low.
Preferably, valve inner is equipped with locating piece, valve shaft both ends are fixed on by guide pad on locating piece, and locating piece leads to
Screw is crossed to be fixed on valve body.Installation is facilitated to safeguard, it is easy to use.
Preferably, nameplate is provided on the outside of valve body.It conveniently indicates unit type, is easy to use.
The beneficial effects of the utility model：
1. whole built-in structure, without the leak source that leaks；
2. compact-sized, structure length only has conventional flange formula check-valves 1/8th to arrive a quarter.
3. small, light-weight, weight only has 1st/20th of conventional flange formula check-valves to arrive a quarter.
4. the pressure loss is smaller, flap is closed rapidly, and quick closedown can be realized before medium counter flow.
5. sealing performance is reliable, service life is long, applied widely.
6. easy for installation, horizontal vertical pipeline can be used.
7. operation and maintenance cost is relatively low..
