Product Description

Basic introduction

Plunger valves are more suitable than discharge valves for systems that require full displacement of valves. Because the process of moving the plunger in the valve chamber is also the process of cleaning the valve chamber, the plunger valve can be used in slurry process media. The design is diverse and can be docked to the outlet of various containers. Line sampling and discharge. Low temperature application is equipped with polyvinyl fluoride, graphite radial seal, high temperature application adopts metal seal. Various operating methods are available, such as manual, pneumatic (spring return type, double acting type, with and without hand wheel), electric, hydraulic, etc. As long as the plunger valve can provide full displacement state of operation. This standard specifies the type, technical requirements and marking of manual plunger type stainless steel discharge valves. petrochemicalThis standard is applicable to the discharge and sampling of all reaction reactors with agitators in chemical and  equipment.

Equipment Performance

(1) Corrosion resistance
1. Polytetrafluoroethylene and metal bonding excellent, general tensile resistance, resistance to dilute acid, concentrated acid, etc
2. The use of medium easy particles, oil, pulp, carbon dioxide (stainless steel minimum use temperature of -100ºC, maximum use temperature of 232ºC)
3. Strictly prohibit the use of fluorine-containing ionic liquids (such as HF, etc.) can not use strong alkali and phosphoric acid (temperature >150ºC concentration >30%)
(2), the general working temperature of stainless steel (medium temperature) is -5~225ºC
(3), nominal pressure of 0.6Mpa
(4), diameter range: 25~250mm

Maintenance and installation precautions

1. The valve should be neatly stored in the general air dry warehouse, it is strictly prohibited to pile or open storage, keep the piston surface free of dirt, sand, etc., but it should be noted that the piston surface should not collide with metal or knock with metal. Both ends of the valve diameter should be blocked with blind plates.
2. Carefully check the valve before installation, and remove the damage caused by the valve during transportation and storage.
3. During installation, attention should be paid to whether the screw force of each part is balanced and whether the lifting (activity) is flexible. Check whether the packing is well sealed in the piston, and shall not be disassembled without permission, under the guidance of technical personnel.
4. The valve should be installed in the place without violent vibration and impact, and the site without damage to the use of the valve.
5. After the valve is installed, check whether the screws in each part are tightened.
6. When the discharge is blocked, metal rods or hard tools can be used to dredge, and metal rods or hard tools must not be used.
7 should try to avoid the alternating use of acid-base medium (in addition to the neutralizing reaction medium), so as not to shorten the life.
8 According to the performance of the medium and the use of the period, should often check the piston surface and packing wear, one side leakage. If any damage is found, it should be replaced and reused in time. The piston face and the oil cup should be lubricated.
9. If the valve surface is found to be damaged, it should be stopped immediately. Special materials can be used to repair the affected area, or the relevant production unit can be commissioned to produce
