Description
Technical field
This utility model belongs to valve field, particularly relates to a kind of hard seal ball valve.This utility model is applicable to high temperature, height
Pressure, abrasive media operating mode.
Background technology
Hard seal ball valve is widely used in high temperature, abrasive media operating mode, uses metal sealing between its valve seat and spheroid
Coordinating, in order to prevent high-temperature expansion that spheroid is stuck with valve seat, general valve seat uses floating structure, utilizes telescopic spring to absorb
Spheroid and the swell increment of valve seat.Its major defect is: under high pressure operating mode, valve seat pretightning force to arrange difficulty relatively big, pretightning force
The least sealing surface is easily revealed, and the biggest switch moment is too big, and sealing surface wear is big, easily pulls sealing in switching process
Face.
Summary of the invention
The purpose of this utility model is the shortcoming existed for prior art, it is provided that a kind of sealing is reliable, it is light, close to open and close
The electro-hydraulic joint control high pressure hard sealing ball valve that front cover abrasion is few.
The technical solution of the utility model includes valve body, valve seat, valve rod, spheroid, YE, spheroid and valve base sealing
Face uses hard sealing structure, and valve rod lower end is fixing with spheroid to be connected, and valve rod upper end is connected with YE power transmission shaft；Mainly
Valve seat uses hydraulic pre-tightening control valve seat, and described hydraulic pre-tightening control valve seat is by ring-shaped cylinder valve body, annular piston chamber and liquid
Pressure controlling organization composition；Annular piston chamber is arranged on body cavity and imports and exports in channel side wall, concentric with valve channel, annular circle
Column valve pedestal is inlaid in annular piston intracavity and constitutes piston structure, is shaped with phase interworking between ring-shaped cylinder valve body front and spheroid
The metallic sealing section closed, the annular piston chamber at the back side and the hydraulic press outlet of hydraulic control；The work electricity of hydraulic press
Source is controlled by the hydraulic control switch in switch board, and YE controls switch and is arranged in switch board.
Preferably, hydraulic control switch and YE control switch and use integrated control switch, and this integrated control switch has " to be opened
Valve position " and " closing valve position "；Integrated control switch is when " valve opening position ", and after first connecting hydraulic control switch, YE is connected in time delay
Control switch；Integrated control switch, when " closing valve position ", is first connected YE and is controlled switch, controlled by closing valve position sensors
Hydraulic control switch is energized.
The utility model has the advantages that valve seat uses hydraulic pre-tightening control valve seat, it seals reliably, opens and closes light, sealing surface
Abrasion is few, it is adaptable to high temperature, high pressure, abrasive media operating mode.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Electro-hydraulic joint control high pressure hard sealing ball valve as shown in Figure 1, including valve body 1, valve seat 2, valve rod 4, spheroid 3, electronic holds
Row device 5, spheroid 3 uses hard sealing structure with valve seat 2 sealing surface, has high temperature resistant, wear-resistant, and valve rod 4 lower end is fixed with spheroid 3
Connecting, valve rod 4 upper end is connected with YE 5 power transmission shaft；Valve seat 2 uses hydraulic pre-tightening to control formula valve seat, described hydraulic pressure pwc
The tight formula valve seat that controls is made up of ring-shaped cylinder valve body, annular piston chamber 6 and hydraulic control 7；Annular piston chamber 6 is arranged on
Valve body 1 inner chamber is imported and exported in the sidewall of passway, and concentric with valve body 1 passage, ring-shaped cylinder valve body is inlaid in annular piston chamber 6
Interior composition piston structure, is shaped with the metallic sealing section cooperated, i.e. valve seat 2 between ring-shaped cylinder valve body front and spheroid 3
Sealing surface, the annular piston chamber 6 at the back side and the hydraulic press outlet of hydraulic control 7, hydraulic press outlet conduit passes through liquid
Pressure valve connects with annular piston chamber 6；The working power of hydraulic press is controlled by the hydraulic control switch in switch board 8, electronic execution
Device controls switch and is arranged in switch board 8, and during valve opening, first the annular piston chamber 6 at valve seat 2 back side is let out by operation hydraulic control switch
Pressure, then connect YE control switch open valve, when closing valve, first connect YE and control switch pass valve, close valve
Connecting hydraulic control switch after putting in place, to make hydraulic press obtain electric, pressurizes to the annular piston chamber 6 at valve seat 2 back side, pushes valve seat 2 to ball
Body 3 seals and coordinates.
Hydraulic control switch and YE control switch and use integrated control switch, this integrated control switch have " valve opening position " and
" close valve position "；When integrated control switch pushes " valve opening position ", first connect hydraulic control switch, by control circuit by annular piston chamber
6 pressure releases, then time delay connection YE control switch, Open valve, make low-pressure opening between spheroid 3 and valve seat 2, open light
Just, sealing surface friction is little；When integrated control switch pushes " closing valve position ", first connect YE and control switch, by valve closing,
After valve closing puts in place, being controlled hydraulic control switch energising by closing valve position sensors, hydraulic press pressurizes to annular piston chamber 6,
Valve seat 2 and spheroid 3 are pressed tight sealing engagement.
