Description

The oblique valve check-valves of flange form
Technical field
The utility model is related to a kind of check-valves, especially a kind of oblique valve 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 key equipment, be applicable in a variety of media, traditional swing check valve, valve deck and valve body are connected by screw bolts, in high pressure Operating mode is in use, being bolted needs very big pretightning force;And because the installation of valve shaft and flap needs the trepanning on valve body, system It makes and processing cost is all higher, and there are leakage points on valve body, flap uses thin type structure lighter in weight, in velocity of medium When larger, larger shock is easily generated to valve body, is not suitable for high temperature and pressure and high flow rate mixture condition.
Utility model content
In order to solve the shortcomings of the prior art, a kind of nothing that the utility model provides leak leak source, flap close it is fast The oblique valve check-valves of flange form of speed.
The oblique valve check-valves of flange form in the utility model, including valve body, flap, stent, support plate and valve deck, in valve body Portion is equipped with medium flow channels, and medium flow channels are from left to right followed successively by input end, valve chamber and the port of export, valve chamber neck import Side is held to be equipped with positive stop lug boss, input end runner is equipped with the changeable type valve seat being in tilted layout, and valve seat right side is equipped with and valve plate The sealing surface of cooperation, seat bottom portion tilt to the right, and valve body is equipped with mounting hole on non-return portion top, lower part holds equipped with reflux medium Receive chamber, positive stop lug boss right upper portion is equipped with the threaded hole for mounting bracket, and flap is rotatably mounted on stent by valve shaft On, medium non-return structure is formed when flap is bonded with valve seat, valve deck is mounted on by support plate on valve body.Stop flow into medium Afterwards, flap forms medium non-return structure under the action of reflux medium and flap dead weight with valve seat, prevents medium back flow;It disassembles The bolt at support plate position, you can carry out flap, valve seat removes and installs, it is simple in structure, it is easy to use.
Preferably, valve seat is 3 ~ 8o with perpendicular inclination angle.Flap adds by dead weight fitting valve seat, stable structure Work is convenient.
Preferably, the conflict extension for limiting flap open position, simple in structure, user are equipped on the right side of flap Just.
Preferably, support plate is equipped with hanging ring.Facilitate lifting valve, it is easy to use.
Preferably, stent is fixed on by support bracket bolt on positioning convex platform.It is simple in structure, convenient for safeguarding.
Preferably, being equipped with sealing ring between support plate and valve deck, wedge sealing ring, wedge are equipped between valve deck and valve body Gasket is equipped between sealing ring and sealing ring;Sealing effect is good, suitable for high temperature and pressure and high flow rate mixture condition.
The beneficial effects of the utility model:
1. built-in structure, valve body is without the leak source that leaks;
2. the pressure loss is smaller, flap is closed rapidly, and quick closedown can be realized before medium counter flow;
3. the flap of optimization design is more suitable for high flow rate mixture condition, shock of the flap to valve body can be effectively reduced;
4. sealing performance is reliable, only relies on flap its own gravity and flap closing and sealing can be realized;
5. valve deck uses pressure self-sealing structure, easy disassembly and there is better seal performance, be more suitable for high temperature height Press operating mode;
6. service life is long, applied widely;
7. operation and maintenance cost is relatively low in valve life cycle.
