Abstract
The utility model relates to a high pressure difference small-flow angle-type control valve, which mainly adopts an executing mechanism and a valve body to be connected into a whole through a round nut. A valve seat is arranged at the bottom part of the valve body, and a valve rod and a packing component are arranged in the valve body. The utility model is characterized in that the upper end of the valve rod is connected with the executing mechanism through a connecting piece Hough; the packing component is arranged on the valve rod; a valve core at the lower end of the valve rod is inserted into a throttle hole of the valve seat; a water outlet is formed in the center of the valve seat, and a cone-shape sealing surface is arranged between the openings of the valve core and the valve seat. The valve core adopts a needle-shape valve core or a spherical valve core or an inverted-cone shaped valve core. The opening between the needle-shape valve core on the valve rod and the valve seat adopts a round hole or a cone-shape hole. The control valve has simple, compact and reasonable structure, can have the sealing property and the anti-scour and anti-cavitation functions, and can achieve the regulating function of the valve to the fluid, thereby effectively and accurately controlling the medium flow passing through the throttle hole of the valve seat.
Description
Technical field
The utility model relates to a kind of High Pressure Difference small flow angle control valve, and the flow process that specifically is used for chemical industry equipment or laboratory equipment is regulated the equipment of flow, belongs to the precision instrument Instrument technology field.
Background technique
Micro-control valve is one of critical component of micrometeor system, almost is indispensable important component part in all micrometeor system, and its performance directly has influence on the working state of whole micrometeor system.Industrial so far control valve has single-seat adjusting valve, sleeve adjusting valve, butterfly valve, ball valve, disconnecting link valve, three-way control valve etc.Because its complex structure, amount of leakage is big, at the bottom of the frequency response, so be not suitable for microminaturization.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby provide a kind of High Pressure Difference small flow angle control valve, when actuator moves, move up and down vertically, the gateway of opening and closing of fault fluid, can realize the regulatory function of this valve convection cell, thereby can effectively accurately control by the dam rate-of flow in hole of valve seat.
The technological scheme that provides according to the utility model, High Pressure Difference small flow angle control valve comprises valve seat, valve rod, valve body and actuator, actuator and valve body are connected to integral body by round nut, valve seat places the bottom of valve body, valve rod and filler assembly place valve inner, feature is that the upper end of valve rod is connected with actuator by the link Hough, filler assembly is housed on valve rod, the spool of valve rod lower end inserts the hole of damming of valve seat, described valve seat center has osculum, is provided with conical seal (contact) face between spool and the valve seat gateway.
Described spool is aciculiform spool or spheroidal spool or turbination spool.Aciculiform spool on the described valve rod and the gateway between the valve seat are shaped as circular port or cone shape hole.Described valve body side flange axis and vertical line angle are chosen as 45 ° or 60 ° or 90 °.
Described actuator can adopt diaphragm actuator, cylinder piston type actuator, electric actuator, hydraulic actuator or pneumatic motor actuator.
Described conical seal (contact) face surface overlaying department titanium Lay alloy.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Can when guaranteeing sealing, can also play antiscour, the effect of anti-cavitation; When actuator moves, the drive valve rod moves up and down, the regulatory function of this valve convection cell can be realized just along with the increase of moving of spool or dwindle in aciculiform spool on the valve rod and the gateway between the valve seat, thereby effectively accurately controls by the dam rate-of flow in hole of valve seat.
Description of drawings
Fig. 1 is the utility model High Pressure Difference small flow dihedral control valve structure sectional view.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1, comprise valve seat 1, valve rod 2, valve body 3, flushing hole 4, oil hole 5,6, filler assembly 7, round nut 8, connection Hough 9, actuator 10 etc.
The utility model actuator 10 is connected to integral body with valve body 3 by round nut 8.Valve seat 1 places the bottom of valve body 3, and described valve seat 1 center has a circular osculum, is stream socket, and its symmetrical layout helps reducing the vibration of fluid system.Valve rod 2 places valve body 3 inside with filler assembly 7, and described valve body 3 side flange axis and plummet angle are chosen as 45 ° or 60 ° or 90 °.The upper end of valve rod 2 is connected with actuator 10 by connecting Hough 9, and the aciculiform spool of valve rod 2 lower ends inserts in the hole of damming (osculum) of valve seat 1, and the gateway between described aciculiform spool and the valve seat 1 is shaped as cone shape hole.Described aciculiform spool is provided with the highi degree of accuracy conical seal (contact) face between valve seat 1 gateway, conical seal (contact) face can be selected surface overlaying department titanium Lay alloy, can guarantee reliable sealing performance.
This control valve MEDIA FLOW to: promptly can be side and enter the end and go out, also can be the end advances side and goes out.Described actuator 10 can adopt diaphragm actuator, cylinder piston type actuator, electric actuator, hydraulic actuator or pneumatic motor actuator.
The utility model control valve is with the main driving element of external final controlling element as movable valve rod axial motion, the intermediate connector Hough is connected the three between actuator and valve rod, have stream socket on the valve seat, the gateway is positioned at the valve seat center, and being furnished with of its symmetry is beneficial to the vibration that reduces fluid system; When actuator 10 action, during the actuator action, drive valve rod and move up and down, aciculiform spool on the valve rod and the gateway between the valve seat be just along with the increase of moving of spool or dwindle, thereby effectively accurately control by the dam rate-of flow in hole of valve seat.
