Abstract
The utility model relates to a three-way stop valve which relates to a device for distributing, conveying or transporting the liquid. The utility model is characterized in that a valve plate and a piston which are connected by a connecting rod are positioned in a three-way body. A hollow cone on the front end of an outlet is sealed by the valve plate, and the piston is in the maximum limit position of a cavity. Both ends of a by-pass pipe are respectively communicated with an inlet end and a pressure regulating port. The disadvantages that the occupation area of a float valve in a fluid conveying pipe is large, and the installation and the maintenance are inconvenient. The utility model is suitable in the line for distributing, conveying or transporting the liquid.
Description
The utility model relates to the device that a kind of liquid distributes, carries or pass on.
In technique known, carry that valve is indispensable part in the pipeline of fluent material, wherein with ball valve, gate valve for.In heavy-caliber pipeline was carried, ball valve was indispensable parts, and the ball float that is equipped with owing to the heavy caliber float valve increases with bore, thereby made installation, maintenance all inconvenient.
The purpose of the utility model is to provide a kind of installation, maintenance convenient to society, utilizes the stop valve of carrying fluid pressure differential to control automatically in the pipeline.
In order to finish the foregoing invention task, the utility model has adopted following scheme when design: 1, connect valve plate (1) with connecting rod (3), piston (2) replaces valve, finishes startup, closing motion.2, finish pressure with modulating valve (5) and regulate, impel piston (2) in cavity (8), to move.Thereby valve plate (1) and piston (2) that connecting rod (3) is connected are arranged in three way valve (11), and the outlet (7) of connecting rod (3) and three way valve (11), control mouthful (5) central lines, and pass the center hole of support (13), hollow cone (12) top of valve plate (1) sealing outlet (7) front end, piston (2) is positioned at the maximum position of cavity (8), and bypass tube (9) one ends of being controlled by modulating valve (4) communicate with import (6), and the other end communicates with cavity (8).
Simple, the easily installation, maintenance of the utility model, manufacturing process that contains above-mentioned design proposal, advantage such as floor space is little, and is easy to operate.
Fig. 1 is a structural representation of the present utility model, section show internal structure and correlation position.
Embodiment of the present utility model is:
For sake of convenience, (6) in the three way valve (11) are called inlet, (7) are called outlet, and (5) are called pressure modulating opening.
With casting method casting three-way valve body (11), inlet, outlet, pressure regulation inlet internal diameter, outer toward identical and have a flange plate.The outlet end center has a center line to overlap with outer pipe, the cone of the level and smooth hollow in top (12), there is the support (13) of a support link (3) at the outlet end center, the pressure modulating opening flange plate links to each other with outlet valve gap (10), communicate with inlet (6) by bypass tube (9) one ends of often opening stop valve (4) control, the cavity (8) that the other end links to each other with pressure modulating opening (5) communicates, and circular valve plate (1), piston (2) are materials such as rubber product.
Assemble sequence of the present utility model is: with three way valve (11) processing of casting, require conical cylinder (12) end face smooth smooth, with connecting rod (3), valve plate (1), the builtup member of piston (2) is sent into by cavity (8), and make valve plate (1) be close to the end face of cylindrical body (6), piston (2) is in the greatest limit position of cavity (8), and valve gap (10) is fastening with the flange of pressure modulating opening (5), and gate valve is loaded on the valve gap (10).
Course of action of the present utility model is: when valve gap (10) opens wide, be transferred liquid and flow into from import (6), liquid is pushed piston (3) to pressure modulating opening end (5), and pressure and piston (3) are when pressure outside equates in cavity (8), and liquid is normally carried.Open normal throttle valve (4), when liquid flows into cavity (8) from bypass tube (9), when eduction valve (5) discharge is less than the flow that enters cavity (8), promote piston (3) to contrary direction motion, the outlet of then closing cone (12) is transferred liquid and stops to flow.
Claims (1)
1, a kind of three-way cut-off valve that is used to carry the action of hydraulic pressure control switch, feature of the present utility model is the valve plate (1) that is connected by connecting rod (3), piston (2) is arranged in three way valve (11), and the outlet (7) of connecting rod (3) and three way valve (11), pressure modulating opening (5) central lines, and pass the center hole of support (13), the hollow cone (12) of valve plate (1) sealing outlet (7) front end, piston (2) is positioned at the position of the maximum cavity (8) of pressure modulating opening (5), bypass tube (9) one ends by gate valve (4) control communicate with import (6), and the other end communicates with cavity (8).
