Abstract
The utility model relates to a flow regulator for a stop valve. A main body in a cylindrical shape comprises double sleeves, both sides of an outer sleeve (1) and an inner sleeve (2) are both provided with liquid inlets (3) with the same area and shape, the inner sleeve (2) is a movable sleeve which is fixedly connected with a joystick (5), and the outer sleeve (1) is a still sleeve which is fixed on a valve body bottom cover (7); the joystick (5) is provided with a needle pointer (4); the upper ends of the double sleeves are opened, the openings are opposite to a valve seat through hole (8) below a valve core, and the lower ends of the double sleeves are provided with center holes which are communicated with a blowdown hole (6) on the valve body bottom cover (7). The flow regulator is cooperated with a stop valve with a pilot valve applied previously and is mounted in the lower throughflow cavity of the stop valve to drive the inner sleeve to make a relative displacement through the rotation of the joystick mounted at the lower part of a valve body so as to generate mutual sheltering, the outlet flow rate of the valve body is affected by the area of the sheltering surface, so that the goal of flow rate control is achieved, and the requirements of various users are met.
Description
Technical field
The utility model relates to a kind of flow regulator of stop valve of follow-on band pilot valve.
Background technique
CN200710004651.8, CN200710004645.2, CN200710004654.1, CN200720111751.6 are my stop valve at the relevant band pilot valve of first to file, these stop valves are the size of uncontrollable flow in use, flow is fixed by the caliber size of import and outlet, timely adjustment as required is difficult to satisfy requirements of different users.
The model utility content
At the above-mentioned deficiency of prior art, to be that design is a kind of be installed in the valve body the purpose of this utility model, the stop valve flow regulator that the big I of flow is regulated as required.
Above-mentioned purpose can realize by following measure: this stop valve flow regulator, comprise governor body, operating handle, scale three parts, body is cylindrical, be double layer sleeve barrel, the inside and outside sleeve both sides all have the area fluid inlet identical with shape, inner sleeve is that moving sleeve is fixedlyed connected with operating handle, outer sleeve is quiet sleeve, be fixed on the valve body bottom, pointer is arranged on the operating handle, two sleeves upper end is uncovered, and this mouthful standard is to the valve seat through-hole of spool below, and the lower end has center hole to communicate with the pollutant exhaust hole of valve body bottom.
The fluid inlet area sum that open the inside and outside sleeve both sides is more than or equal to the area of valve seat through-hole.
The beneficial effects of the utility model are install this regulator in above-mentioned modified model stop valve after, and the flow of the fluid of regulation valve body outlet at any time adapts to requirements of different users as required.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the mounting point figure of this regulator in stop valve.
Embodiment
The utility model is described in detail below in conjunction with embodiment and with reference to accompanying drawing: referring to Fig. 2, the body of this regulator is installed in the following through-flow chamber of stop valve, the uncovered standard of upper end is to valve seat through-hole 8, outer sleeve 1 lower end is fixed on the bottom 7 of valve body, inside and outside sleeve 1,2 lower end center holes communicate with the pollutant exhaust hole of bottom 7, inside and outside sleeve 1,2 both sides fluid inlet areas are identical with shape, when four mouths are aligned with each other, the inlet flow rate maximum, during with operating handle 5 rotation inner sleeves 2, static outer sleeve 1 produces relative displacement with inner sleeve 1, the lateral section of relative in twos four imports 3 hides mutually, and flow reduces, and the side of turn to four import 3 all hides mutually again, the flow minimum flows into hardly.Therefore, rotate inner sleeve 2 by operating handle 5 and reach the effect of regulating flow, weigh the different scale values of turn and the relation of flow size by the value on the 4 indication scales 9 of the pointer on the operating handle 5 again.The stop valve of this regulator is installed, fluid enters into two side-entrances 3 of flow regulator inside and outside sleeve by the import of valve body and enters in the regulator, therefore go out through the outlet of valve seat through-hole 8 again, by just can play the purpose of adjusting stop valve rate of discharge to the adjusting of the discharge value of four fluid inlets 3 in flow regulator inside and outside sleeve both sides to valve body.The area sum of the fluid inlet 3 that open the inside and outside sleeve both sides is in order not influence the performance of the potential of valve body peak rate of flow because of being provided with of regulator more than or equal to the area of valve seat through-hole 8.
Claims (2)
1, a kind of stop valve flow regulator, comprise governor body, operating handle (5), scale (9) three parts, it is characterized in that body is cylindrical, be double layer sleeve barrel, inside and outside sleeve (1,2) both sides all have the area fluid inlet identical with shape (3), inner sleeve (2) is a moving sleeve, fixedly connected with operating handle (5), outer sleeve (1) is quiet sleeve, the lower end is fixed on the valve body bottom (7), and pointer (4) is arranged on the operating handle (5), and two sleeves upper end is uncovered, this mouthful standard is to the valve seat through-hole (8) of spool below, and the lower end has center hole to communicate with the pollutant exhaust hole (6) of valve body bottom (7).
2, stop valve flow regulator as claimed in claim 1 is characterized in that fluid inlet (3) the area sum opened said inside and outside sleeve (1,2) the both sides area more than or equal to valve seat through-hole (8).
