fire fighting gate valve,
fire check valve
This butterfly vavle is suitable on system such as petroleum, chemical industry, foodstuff, medicine, papemaking, water and electricity, shipping, plumbing, the smelting and sources of energy etc the pipe route. Can regard on gas, liquid, semifluid as well as solid powder pipes and power lines and the container of many kinds of corrosiveness and non-corrosiveness adjusts and dams a river the equipment use. Especially extensively being in high layer of building fire protection system reaches other to show in the pipes and power lines system of valve of vavle switch state.
The disc of the wafer type butterfly valve is installed in the diameter direction of the pipe. In the cylindrical passage of the butterfly valve body, the disc-shaped disc rotates around the axis, and the rotation angle is between 0°-90°, which can play the role of flow regulation. When the disc rotates to 90°, the valve reaches the maximum. Opening degree.
The clip-on butterfly valve is simple in structure, small in size and light in weight, and consists of only a few parts. Moreover, it can be quickly opened and closed by only rotating 90°, and the operation is simple, and the valve has good fluid control characteristics.

1. This signal butterfly vavle is by the pot wheel worm-drive device drive tuming axle and the butterfly board revolving realizes opening and close and controls the volume of flow.
2. Revolving the worm gear worm-drive device handwheel, making butterfly board achieve the purpose opening and close and adjusts the volume of flow, that the handwheel clockwise revolves closes down for the vavle.
3. The worm gear worm-drive device chest is set up the microswitch inside the body and is had two of versions:
(1) At the gearing chest has out inside the body to and the pass to two microswithchs. Two swithchs move respectively at the valve atandard-sized sheet with when cutting otu, the pilot lamp power supply in the connection control room "vavle leaves" "vavle pass", mades accurately shows the vavle switch state.
(2) In the gearing chest body. The signal is closed down by the export vavle to the microswitch action when the butterfly board is by 0~40 degrees seat, and another can be sended out the vavle and opening the signal to often closing the contact during 40~90 degrees seat. Can adjust the cam that the pressure was touched the microswitch, and show the different seats of butterfly board place.
1. Small in size and light in weight. Easy instllation and mintenance. It can be mounted wherever neded.
2. Siple and compact construction, quick 90 degrees on-off operation.
3. Miniminzed operating torque, energy saving.
4. Flow curve tending to straight line. Excellent regulation performance.
5. Long service life. Standing the test of tens of thousands opening/closing operations.
6. Bubbles-tight sealing with no leakage under the pressure test.
7. Wide selection of materials, applicable for various mdeium.
8. Gate vavle, globe vavle, cock, glue pipe vavle and diaphragm vavle altogether, eapecially reaching and need show in the pipes and power liners system of vavle switch state at high layer of building fire protection system, all available this vavle is replaced.
