Description
Technical field
Valve technology field is the utility model is related to, especially a kind of Slow Close Valve.
Background technology
Valve be in fluid system, for control the direction of fluid, pressure, flow device, be to make pipe arrangement and equipment
Interior medium（Liquid, gas, powder）Flowing stops and can control the device of its flow.The control of valve can use a variety of biographies
Flowing mode, such as manually, electrically, surge, pneumatically, turbine, electromagnetic driven, electromagnetism surge, electro-hydraulic dynamic, air-or liquid-operated, spur gear, bevel gear
Driving etc..
General check valve refers to flow in itself by medium and automatic open and close flap, for preventing medium from flowing backwards.Using
During, when the pressure and flow of pipeline internal medium change, the quick opening and closing of flap are likely to result in, then
Larger impact and vibrations are produced to valve body and valve seat, influence valve service life.Meanwhile the quick closedown of check-valves is easily produced
Raw water hammer, can be caused greatly to destroy to whole pipe-line system.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of Slow Close Valve, solves in prior art pipeline and is situated between
When the pressure and flow of matter change, the quick opening and closing of flap are likely to result in, valve body and valve seat produce larger
Impact and vibrations, influence valve service life, easily produce the problem of water hammer.
The utility model is achieved through the following technical solutions：
A kind of Slow Close Valve, including valve body, valve seat, flap, rocking arm, rocking arm bearing pin, the valve seat are located at the interior of valve body
Portion, the valve seat side of the valve body are provided with flap, and the rear side of the flap is provided with rocking arm, and the rocking arm is consolidated with flap by bearing pin
Fixed, the rocking arm upper end is rocking arm bearing pin, and the rocking arm bearing pin is provided with slow closing device.
The further improvement project of the utility model is the slow closing device pneumatic element and counterweight, the pneumatic member
Part includes cylinder, cylinder cap, piston, piston rod, spring, and the cylinder cap is located at cylinder lower end, and the piston is located at cylinder interior, institute
State piston rod and be located at piston upper end, be provided with spring between piston and the cylinder upper end, the piston rod is connected with counterweight, institute
Counterweight is stated to be fixed on rocker arm shaft.
The further improvement project of the utility model is that the cylinder is connected with air accumulator by breather pipe, the gas storage
Tank is located at valve body outer tip end, and the breather pipe is provided with gas pin valve.
The further improvement project of the utility model is that the valve body centre position is provided with nameplate.
The further improvement project of the utility model is, the valve body upper end is provided with bonnet, the bonnet by rivet with
Valve body is fixed, and the bonnet is provided with hanger.
The utility model compared with prior art, has the following advantages that：
1st, a kind of Slow Close Valve, on the bearing pin of rocking arm swing check valve, slow closing device, slow closing device driving are set up
Band motion rocker arm, so that flap slowly opens and closes, impact and vibrations are reduced, extends the service life of valve.
2nd, slow-to-fast-slow three-stage action process：Using the valve of air-cylinder type slow closing device during opening and closing,
Always meet three states of experience, i.e., slow, fast, slow three-stage process together.The slow motion in beginning and end stage mitigates impact, middle
The quick acting of process can make valve quick in place, reach protective effect.
3rd, die defencive function：Because the executing agency of valve needs external pressure gas source, supplied to tackle possible source of the gas
Gas instability problem, the slow closing device are furnished with air accumulator and air lock.In the case where bleed pressure disappears, it can be ensured that valve
It can at least realize more than 3 and act.In order to ensure the stability of return valve function, a whole set of slow closing device is interrupted and stored up in source of the gas
The situation that gas tank storage pressure exhausts, remains to only realize conventional check-valves work(by pipeline interior media pressure-driven flap
Energy.
4th, responsiveness is adjustable：According to the difference of valve applying working condition, the thrust of medium is different when check-valves opens and closes.
Slow closing device can be by modes such as the position of adjustment hammer and pneumatic element manipulation states, to three works of Slow Close Valve
It is adjusted as state, so as to adjust the molar behavior time of valve.
The utility model is described further with reference to the accompanying drawings and examples.
