Abstract
A gas liquid type piston valve belongs to the technical field of valve design and manufacture, and the piston valve consists of a valve body and a valve lid. A piston body is arranged in the valve body, the piston body is provided with a piston and a piston rod. The underside of a right side supported cover in the valve body is provided with a valve seat. The piston divides the valve cavity into a left cavity and a right cavity. Two sides in the lower part of the valve body are respectively provided with a gas inlet. When in use, the piston valve is installed on the industrial circulating cooling water pipeline. The working principle is as follows: the compressed air or hydraulic oil enters the a cavity from an inlet A to push the piston move right, the piston rod chokes the valve opening, and the valve is closed. On the contrary, when the compressed air or hydraulic oil enters the b cavity from an inlet B, the piston rod is pushed to move left, the piston rod moves from the valve opening, and the valve is open. The characteristics of the product are as follows: the hydraulic pressure or gas pressure keeps the closest contact between the piston rod and valve opening after long use, although the valve opening has abrasion. The close is tight, so the long time use is maintained, and the servicing rate of the equipment is reduced. The utility model is an ideal valve used in industrial production.
Description
Technical field
The utility model belongs to the design and the manufacturing technology field of valve.
Background technique
Be widely used in the various valves on metallurgy, chemical industry or industrial circulating cooling water and the water-supply systems at present, as electronic or Pneumatic butterfly valve, gate valve, stop valve etc.Because the reason in the design makes valve wearing and tearing occur through long-term operation and at the valve port place, and causes the phenomenon of dielectric leakage.Not only influence the ordinary production life, maintenance is also inconvenient especially.Therefore say that the various valves that use at present are not very desirable.
Summary of the invention
The purpose of this utility model provides a kind of valve port can realize the gas liquid type piston valve of compensation automatically after through wearing and tearing.To solve the practical problem that existing product exists.
The utility model structure is as shown in drawings: be made of valve body and valve gap.On valve body, have valve gap.Valve body is connect by bolt mutually with valve gap.One piston body is arranged in valve body.Have piston on the piston body.Have a piston rod on the piston.Piston rod and piston are welded as a whole.Piston rod is a hollow-core construction.There is a supporting sleeve on the right side in valve body.One valve seat is arranged below the supporting sleeve.Supporting sleeve is connect by the valve seat bolt mutually with valve seat, and a seam is arranged on valve seat, has valve port on the seam.Piston separates two chambeies about formation with valve pocket, and left chamber is a chamber, and right chamber is the b chamber.In the valve body lower portion left side one suction port A is arranged, one suction port B is arranged on the right side, bottom of valve body.Suction port A and a chamber together with, suction port B and b chamber together with.One measuring rod is arranged on piston body.One indicator board is arranged on the measuring rod.Indicator board is fixed on the measuring rod by nut.At measuring rod outside suit one fixed cover.Have the measuring rod seal ring in the fixed cover inboard.On the fixed cover outside, have the fixed cover seal ring.One guide ring is arranged on piston body.One O RunddichtringO is arranged in the guide ring inboard.In the front portion of piston rod one combined type packing ring is arranged.One valve seals is arranged between valve body and valve gap.Front and rear at piston rod respectively has a dust ring.Use of the present utility model is that it is installed on the industrial circulating cooling water pipeline.Be normally open at ordinary times.Its working principle is: when using Pneumatic actuator, pressurized air enters a chamber from the A mouth, promotes piston and moves right, and piston rod is blocked valve port, and valve is closed condition.Conversely, when pressurized air entered the b chamber from the B mouth, pressurized air then promoted piston rod and is moved to the left, and broke away from valve port, made valve be opening state.The opening and closing of this product both can pneumatic mode, also can adopt the mode of surging.As the employing mode of surging, then on suction port A and suction port B, be connected hydraulic system.This product characteristics is through after long-time the use, though also have wearing and tearing at the valve port place, but close and unlatching is by pneumatic or surge and promote piston rod and realize that so no matter how valve port weares and teares, hydraulic pressure or air pressure all can contact piston rod with the valve port maintenance the most closely.Close tightly, pipeline internal medium is not prone to leakage, so can keep long-time use.Keep industrial production to carry out continuously, reduced the maintenance rate of equipment.It is a kind of desirable industrial production valve.
