What are the functions of the locking valve and the regulating valve

The locking valve is composed of an oil circuit plate, a valve core, a seat and a locking tissue.

A valve seat connected with the valve core is installed in the lock hole of the oil circuit plate. The locking cap on the valve seat with a torsion spring, a ratchet mechanism and a ratchet wrench refers to the locking organization. The oil circuit plate has three passes, one is the bypass valve cap, and the valve core also has three full-line through holes corresponding to the oil circuit plate. After adjusting the valve core part, the ratchet wrench lock cap is screwed on, at this time the customer can not open it independently. "Regulating valve" mainly has two general meanings, one refers to the gate valve through a variety of fluid data flow (flow speed) in the control pipeline, and the other refers to the valve in the automatic control system has a strict relationship with the data flow and can accept long-distance signal control of the gate valve; Lock valve refers to a certain environment can lock the gate valve area of the gate valve.

Under certain conditions, they can be the same gate valve. For example, there is a gate valve in the water heating project, which can be manually locked after the personnel change to the appropriate opening degree (management method), so that the user can not adjust it independently.

The locking valve has the function of phase change and locking, which can control the conduction of heating and water supply equipment by one household and one group, and can not be opened without destruction to complete effective management.

With magnetic locking valve, it is through the magnetic force to open and cancel the closing part of the pressure regulator, which is a magnetic lock. It is generally used on gate valves with some important and unique position and direction functions to avoid gate valves being applied by random power switches. No gap, anti-blocking, moisture-proof, anti-corrosion, easy to use; Favored by power supply, heating, natural gas, solar water heaters and other fields.

Daily maintenance of lock valve

1. Pay special attention to the natural environment of the gate valve, which should be stored in a dry and ventilated room and block both sides of the channel.

2, the gate valve should be regularly maintained, and remove the waste in it, wipe the anti-rust agent is in the surface.

3, after the installation and application of the gate valve, regular maintenance should be carried out to ensure its normal operation.

4, should inquire whether the valve sealing surface is damaged, and according to the actual situation to repair and replace.

5. Check the trapezoidal thread wear condition of the valve seat and stem nut, and whether the filling material is outdated and ineffective, and carry out the corresponding disassembly.

6, to solve the sealing characteristics of the gate valve test to ensure its characteristics.

7, the operation of the gate valve should be intact, flange and support frame in the anchor bolt is complete, high quality screw, no loose condition.

8, if the spindle is lost, it needs to be fully equipped in time, and can not be replaced with a adjustable wrench.

9, packing gland can not tilt or no torque gap.

10, if the gate valve use scene is more extreme, it will be affected by rain and snow weather, dust, sand and other dirt, you should assemble a protective cover for the seat.

11, the standard in the gate valve to keep detailed, precise, clear, gate valve seal, backboard.

12, thermal insulation clamp shall not have dents, cracks.
