Abstract
The utility model relates to an adjusting valve for use in a heat supply pipe network and a heat circulation pipe network in an electric power plant, in particular to a shock-restraining zero-leakage adjusting valve for a spring. The shock-restraining zero-leakage adjusting valve for the spring comprises a valve body, a valve cover, an upper flange, a valve seat, a throttling sleeve, a valve clack, a spring seat, a spring, a spring guide sleeve, a fastening screw, a valve rod, a valve rod gland, a sealing ring, an executing mechanism, a sealing gasket, a filler, a bolt and a nut, and is characterized in that: pre-compression of the spring is overcome through the valve rod, and the end face of the valve rod is sealed with the lower end of the valve clack, so that the sealing performance of the adjusting valve is high; and the leakage amount can be zero. Moreover, the flow of a medium in the adjusting valve can be adjusted through a through hole formed in the side wall of the throttling sleeve, and adjustment is accurate.
Description
Technical field
The utility model relates to the modulating valve of using in a kind of heating network and the power plant's thermal cycle pipe network, relates in particular to spring and presses down shake zero leakage modulating valve.
Background technique
In heating network and power plant's thermal cycle pipe network, all to control the flow of medium in the pipe network, to reach energy-conservation and available heat circuit purpose.Like this will be on pipe network the install adjustment valve, achieve the above object.And present employed modulating valve; Its flap is that awl is curved, leans on moving up and down of conical section flap to regulate the flow of medium in the pipe network, and the conical flap in the modulating valve will often receive impact and the vibrations of pressure medium in the pipe network and corrode; Make conical flap distortion; Cause the Flow-rate adjustment of medium in the pipe network inaccurate, poor sealing performance, working life is short.
The model utility content
The purpose of the utility model is that to regulate inaccurate, poor sealing performance, working life short in order to overcome existing regulating valve flow, and a kind of flow that can regulate medium in the pipe network accurately is provided, good seal performance, and the spring of long service life presses down shake zero leakage modulating valve.
The technical solution that realizes the utility model purpose is: a kind of spring presses down shake zero leakage modulating valve; Comprise valve body, valve gap, upper flange, valve seat, orifice sleeve, flap, spring seat, spring, spring guide, Cock screw, valve rod, valve spindle gland, seal ring, actuator, sealing gasket, filler, bolt and nut; Body cavity is equipped with sealing gasket, valve seat, orifice sleeve, end cap, filler in proper order, covers upper flange; Upper flange is connected with valve body through bolt; Valve rod stretches out from the valve gap middle part, and actuator is fixed on valve gap and is connected with valve rod, it is characterized in that; This flap lower end is provided with through hole and sealing surface, and the upper end is provided with the runner hole of screw thread and closure gasket groove, intermediate arrangement; The shaft shoulder in the middle of this valve rod is provided with screw thread, and the lower end is provided with sealing surface.Spring guide is fixed on the valve rod lower end through screw thread, and spring, spring seat are enclosed within the valve rod lower end successively; Again with pack into the runner hole of flap intermediate arrangement of the assembly of valve rod; This valve spindle gland intermediate hole passes valve rod and is fixed on the flap upper end through screw thread, and valve spindle gland is provided with equalizing orifice.During actual the use, actuator drives this modulating valve and closes, and valve rod drives flap and in valve gap, orifice sleeve, moves down, and until flap and valve base sealing, valve rod overcomes the precompression of spring again, valve rod end face and the sealing of flap lower end; Modulating valve just can cut off medium in the chamber, the left and right sides like this, and the precompression of spring overcomes the impact and the vibrations of medium, makes the modulating valve good seal performance; Leakage rate can reach zero.Actuator drives this modulating valve and opens, and valve rod drives flap and in orifice sleeve, upwards moves, and the through hole that will open through the orifice sleeve sidewall from the right-hand member of valve body of the medium in the modulating valve flow into the outlet of modulating valve left end again through the middle through hole of valve seat like this; The flow of medium just can be regulated through the through hole of opening on the orifice sleeve sidewall in the modulating valve, regulates accurately.
The utility model compared with prior art, its remarkable advantage is:
1, can regulate the flow of medium in the pipe network accurately;
2, vibration-inhibition, good seal performance;
3, long service life;
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is that the A of Fig. 1 is to view.
Embodiment
Below in conjunction with accompanying drawing, specify the mode of execution of the utility model.
In conjunction with Fig. 1, Fig. 2; A kind of spring presses down shake zero leakage modulating valve; Comprise valve body 1, valve gap 8, upper flange 16, valve seat 2, orifice sleeve 3, flap 11, spring seat 4, spring 5, spring guide 12, Cock screw 13,14, valve rod 19, valve spindle gland 7, seal ring 6, actuator 9, sealing gasket 10, filler 15, bolt 18 and nut 17; Valve body 1 inner chamber is equipped with sealing gasket 10, valve seat 2, orifice sleeve 3, end cap 8, filler 15 in proper order, covers upper flange 16, and upper flange 16 is connected with valve body 1 through bolt 18, and valve rod 19 stretches out from valve gap 8 middle parts; Actuator 9 is fixed on valve gap 8 and is connected with valve rod 19; It is characterized in that these flap 11 lower ends are provided with through hole and sealing surface, the upper end is provided with the runner hole of screw thread and closure gasket groove, intermediate arrangement; The shaft shoulder in the middle of this valve rod 19 is provided with screw thread, and the lower end is provided with sealing surface.Spring guide 12 is fixed on valve rod 19 lower ends through screw thread, and spring 5, spring seat 4 are enclosed within valve rod 19 lower ends successively; Again with pack into the runner hole of flap 11 intermediate arrangement of the assembly of valve rod 19; These valve spindle gland 7 intermediate holes pass valve rod 19 and are fixed on flap 11 upper ends through screw thread, and valve spindle gland 7 is provided with equalizing orifice.During actual the use, actuator 9 drives this modulating valve and closes, and valve rod 19 drives flap 11 and in valve gap 8, orifice sleeve 3, moves down, and until flap 11 and valve seat 2 sealings, valve rod 19 overcomes the precompression of spring 5 again, valve rod 19 end faces and the sealing of flap 11 lower ends; Modulating valve just can cut off medium in the chamber, the left and right sides like this, and the precompression of spring 5 overcomes the impact and the vibrations of medium, makes the modulating valve good seal performance; Leakage rate can reach zero.Actuator 9 drives this modulating valve and opens; Valve rod 19 drives flap 11 and in orifice sleeve 3, upwards moves; The through hole 20 that will open through orifice sleeve 3 sidewalls from the right-hand member of valve body 1 of medium in the modulating valve flow into the outlet of modulating valve left end again through the through holes in the middle of the valve seat 2 like this; The flow of medium just can be regulated through the through hole of opening on orifice sleeve 3 sidewalls 20 in the modulating valve, regulates accurately.
