Abstract
The utility model relates to a ball type flow rate balance valve, which is composed of a shell (1), a ball valve (2), a left sphere press cover (3), a right sphere press cover (4), a balance piston device (6), a diaphragm (7), a bearing spring (8), a spring cover (9) and a lock cover (10), wherein an outlet end and a communicating hole (A) of a lower cavity (70) of the diaphragm (7) are arranged on a valve body to lead upstream pressure P1 and downstream pressure P2 to establish connection with the lower cavity (70) of the diaphragm (7). The balance piston device (6) is driven to automatically move up and down, automatically adjusts and stabilizes downstream pressure and flow rate through the diaphragm (7). The utility model is especially suitable for using for the pressure of a heating pipeline and automatic flow rate adjustment, with the advantages of simple structure and easy manufacture.
Description
Technical field
The utility model pipeline pressure automatic balancing valve is especially for hot duct pressure and the automatic adjustment valve of flow.
Background technique
Equilibrium valve all is a kind of stop valve structure form in the prior art, domestic have a lot of manufacturer production, and concrete structure is different, the performance difference, its characteristics are respectively arranged, but the equilibrium valve structural volume of stop valve structure form is big, resistance coefficient is high, manufacturing cost is higher.
The model utility content
The purpose of this utility model provides a kind of simple in structure, makes easyly, uses the good ball formula flow balance valve of fruit.
The utility model is by housing 1, ball valve 2, left and right sides spheroid gland 3,4, equalizing piston device 6, barrier film 7, pressure-bearing spring 8, spring cup 9, locking closure 10 constitutes, ball valve 2 is by spheroid 21, axle journal 22, axostylus axostyle 23 one constitute, in ball valve 2, offer inner chamber 25, ball valve 2 is rotatably assorted with housing 1 by its axle journal 22 and axostylus axostyle 23, left and right sides spheroid gland 3,4 are connected with housing 1 screw-thread fit and cooperate with spheroid 21 and form valve port, equalizing piston device 6 is by balance spring 60, piston 61, live and match connecting rod 63, barrier film connecting cleat 64,65 form, spring cup 9 is bolted to connection with housing 1, it grips barrier film 7 outer shroud edges simultaneously, the piston 61 of equalizing piston device 6 is slidingly installed in ball valve 2 inner chambers 25, barrier film 7 middle parts are by barrier film connecting cleat 64,65 match connecting rod 63 with work is connected, on spheroid 21, offer valve opening arranged evenly 20, on valve body, offer outlet end and barrier film 7 cavity of resorptions 70 intercommunicating pores are pressure compensation opening A.
In the utility model when work,, because upstream pressure P1 is communicated with by balance hole A greater than behind downstream pressure P2, barrier film 7 cavity of resorptions 70 and the valve, barrier film 7 epicoeles 72 pressure are greater than barrier film 7 cavity of resorptions 70, and barrier film 7 is moved down by upper pressure, up to pressure-bearing spring 8 thrust-balancings; When upstream pressure P1 increased, barrier film 7 drove equalizing piston device 61 and moves down, and reduces the valve opening flow path, and barrier film 7 is set up new balance, pressure P 2 and flow behind the venting valve with pressure-bearing spring 8 thrusts; When upstream pressure P1 reduced, pressure-bearing spring 8 promoted to move on the equalizing piston device 6, increases the valve opening flow path, and barrier film 7 is set up new balance, pressure P 2 and flow behind the venting valve with pressure-bearing spring 8 thrusts.Close valve and close when ball valve 2 spheroids 21 revolve when turning 90 degrees its valve opening 20.
The utility model is simple in structure, makes easyly, and using effect is good, is particularly suitable for hot duct pressure and flow and regulates use automatically.
