Abstract
This utility model relates to the single-seat valve of a kind of effective reduction noise, belongs to flow control valve field.Filler assembly is put in bonnet, fairlead and bonnet, interference fits, valve seat puts into valve body, sealing gasket is had between valve seat and valve body, valve core rod is positioned at valve body and contacts with valve seat, it is characterised in that: double-layered noise reduction cage is between bonnet, and valve seat and double-layered noise reduction cage is pressed on valve seat by bonnet,.Advantage is novel structure, widen the range of such valve, only change sleeve and just can change applying working condition, part universality is strong, modularized design, as long as conversion sleeve just can be combined into different product, on the basis of meeting flow and discharge characteristic, noise reduction is obvious, is particularly useful for gas and steam occasion, and double-deck noise reduction cage design makes the local pressure loss of medium minimize.
Description
Technical field
This utility model belongs to flow control valve field, refers in particular to the single-seat valve of a kind of effective reduction noise.
Background technology
At present, in petrochemical plant, common single-seat valve usage amount is very big, is commonly used to the low pressure occasion of various medium.Along with petrochemical equipment is increasingly tighter to the requirement of valve, this structure is that gas, the use occasion of steam occur in that bigger limitation at medium, especially cannot be to the control of noise so that user requires to change valve, or Solve on site noise problem.At present following solution is mainly taked for this problem: one piece of noise reduction orifice plate is installed, to carrying out noise reduction after valve on the pipeline after valve.But taking the method to need pipeline to redesign, reserve installing space, user is the most passive.
Summary of the invention
This utility model provides the single-seat valve of a kind of effective reduction noise, to solve the problem that the most commonly used single-seat valve noise cannot obtain controlling.
This utility model adopts the technical scheme that: filler assembly is put in bonnet, fairlead and bonnet, interference fits, valve seat puts into valve body, sealing gasket is had between valve seat and valve body, valve core rod is positioned at valve body and contacts with valve seat, and double-layered noise reduction cage is between bonnet, and valve seat and double-layered noise reduction cage is pressed on valve seat by bonnet,.
Described double-layered noise reduction cage is made up of with the inner layer sleeve being covered with aperture the outer layer sleeve being covered with aperture, and the little hole number summation on every layer of sleeve differs, and the diameter of described aperture is 3 millimeters, and the gap between two sleeves is 5-10 millimeter.
The utility model has the advantages that novel structure, widen the range of such valve, being entered high-end product sequence by low side, only change sleeve and just can change applying working condition, part universality is strong, modularized design, as long as conversion sleeve just can be combined into different product, on the basis of meeting flow and discharge characteristic, noise reduction is obvious, being particularly useful for gas and steam occasion, double-deck noise reduction cage design makes the local pressure loss of medium minimize.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of this utility model double-layered noise reduction cage；
In figure: 1. valve body, 2. sealing gasket, 3. valve seat, 4. valve core rod, 5. double-layered noise reduction cage, 6. fairlead, 7. bonnet, 8. filler assembly.
Detailed description of the invention
Filler assembly 8 is put in bonnet, 7, fairlead 6 and bonnet, 7 interference fits, valve seat 3 puts into valve body 1, sealing gasket 2 is had between valve seat 3 and valve body 1, valve core rod 4 is positioned at valve body 1 and contacts with valve seat 3, and double-layered noise reduction cage 5 is between bonnet, 7 and valve seat 3 and double-layered noise reduction cage 5 is pressed on valve seat 3 by bonnet, 7.
Described double-layered noise reduction cage 5 is made up of with the inner layer sleeve 502 being covered with aperture the outer layer sleeve 501 being covered with aperture, and the little hole number summation on every layer of sleeve differs, and the diameter of described aperture is 3 millimeters, and the gap between two sleeves is 5-10 millimeter.
Operation principle:
When valve core rod 4 is lifted up, fluid feeding cavity on the left of valve body 1 connects with the fluid issuing chamber on the right side of valve body 1, fluid will flow through double-layered noise reduction cage 5 in flow process, on every layer of sleeve, the foraminate quantity of institute is the most different, owing to every layer of sleeve has bigger flow resistance, a suitable voltage drop element, plays Noise Reduction.
