The working principle of pneumatic valve anti-theft lock

anti-theft lock pneumatic valve is not in time according to the heating system using the unit cost and bunkering incidents happen in the oilfield losses and workshop design success of pneumatic valve products by pneumatic valve, pneumatic ball valve, pneumatic valve, butterfly valve hydraulic control. The pneumatic valve has good anti-theft performance ( Three insurance, the stability of switch easily, sealing effect, with long service life, etc. Anti-theft lock pneumatic valve has the following advantages:
, small flow resistance. Pneumatic valve internal media channel is direct, medium flows in a straight line, small flow resistance.
more effort, opening and closing. Is compared with the pneumatic valve, because whether on or off, ram direction perpendicular to flow direction of medium. Height is big, opening and closing time is long. Gate opening and closing of the trip is bigger, is through the screw.
and water hammer is not easy to produce. Reason is the closing time is long.
on both sides, medium to any direction, easy to install. Brake pneumatic valve channel is symmetrical on both sides.
length and structure ( The distance between the two connection system shell end face is smaller.
and sealing surface wear easily, affect the service life. Open/close the gate two sealing surface sliding friction with the pneumatic valve seat, to medium pressure easy cause abrasion wear, affect the sealing performance, shorten service life.
and more expensive. Contact seal face more, processing more complex, especially the gate seat sealing surface is not easy to processing, and more parts.
, the structure of the form is simple, short length, good manufacturing technology, wide application scope.
anti-theft lock the shortcoming of pneumatic valve is as follows: easy cause erosion and abrasion, surface maintenance more difficult. Dimension is bigger, open needs certain space, open and close time is long. The structure is complex. Brake wide variety, according to the sealing surface configuration can be divided into the wedge disc brake pneumatic valve, pneumatic valve and parallel disc brake wedge disc brake pneumatic valve can be divided into: single gate type, double disc and flexible disc; Parallel disc brake pneumatic valve can be divided into single ram and double ram. According to the threads of the pneumatic valve stem position, can be divided into pneumatic rising stem gate valves and pneumatic non-rising stem gate valve two kinds. Structure features: on the market for a long time to use the general lock with pneumatic valve leakage or rusty phenomenon, the company introduced the European high-tech rubber and pneumatic valve manufacturing technology of the elastic base seat of pneumatic seal gate valve, overcomes the general brake pneumatic valve seal bad, rust and other defects, elastic pneumatic valve seat sealing gate using elastic disc produce elastic deformation compensation effect to achieve good sealing effect, the pneumatic valve switch with light, reliable sealing, good elastic memory and service life etc. Can be widely used in tap water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, shipbuilding, metallurgy, energy systems such as body line used as adjustment and the closure device.
brake pneumatic valve features: light weight: ontology by senior black ball made from cast iron, weight than traditional brake pneumatic valve about % ~ % reduction in weight, easy installation and maintenance. Flat type brake block: traditional brake pneumatic valve often wash the tube in the water after the external objects such as stone, wood, cement, iron filings, sundry sedimentation on the bottom of the pneumatic valve, such as the slots, easy to build into cannot close tightly and form slack phenomenon, at the bottom of the pneumatic valve sealing gate of the elastic base seat of mining with water pipe with flat design, not easy to cause debris deposition, make the flow unimpeded. The overall plastic bags: ram is made of high quality rubber, outsourcing, the whole Europe first-class rubber vulcanization technology make the gate to ensure accurate after vulcanization of geometry size, and rubber and ductile cast gate, then fall off not easily and elastic memory preferred. Precision pneumatic valve, pneumatic valve adopts precision casting, precision pneumatic valve body geometry size of the internal guarantee without any finishing pneumatic valve's sealing.
