Abstract
The utility model relates to a telescopic flexible valve which comprises a valve body, a valve cover matched with the valve body, a pressing cover matched with the valve cover, a valve core matched with an inner cavity of the valve body, a valve rod connected with the valve core, a hand wheel connected with the valve rod and a sealing member, wherein the end head of the valve body is provided with a telescopic flange which is in a sliding fit with an inner hole of the valve body, the matching point is provided with a sealing ring and a telescopic adjusting device is arranged between the telescopic flange and the valve body. The utility model has the functions of valves and expansion pieces. The utility model has the advantage of simple structure, convenient construction and low cost. The utility model can be used as a universal valve of different types. The utility model is used for water supplying and discharging pipe network systems.
Description
The utility model relates to a kind of valve and particularly relates to a kind of telescopic elastomeric valves.
Various General valves are water supply and sewage pipe network system important component parts as gate valve, stop valve and butterfly valve etc., and the water supply and sewage pipe network system is controlled, and realize transferring stream, switch and damming, and guarantee the pipe network system safe and reliable operation.And pipeline extension device is an indispensable piping attachment in the water supply and sewage pipe network system, and it guarantees the pipe network system installation, maintenance, changes carrying out smoothly of part and accident maintenance.At present, used pipeline extension device is formed by the gland flange that is connected with the first pipe flange and with the telescopic pipe that the gland flange endoporus is slidingly matched, and the flange of telescopic pipe is connected with the second pipe, thereby realizes the connection of first, second pipe.Since telescopic pipe can be in gland flange move left and right, the distance of regulating the first and second pipe joints is connected and fixed gland flange and first pipe flange after waiting to set up with bolt, finish the connection of pipeline.Valve that uses in the water drainage-supply system pipe network and deferent expansion bend are two independently engineering goods, must buy simultaneously in pipe-networks engineering, install respectively, and be very inconvenient, and engineering cost is higher.
The purpose of this utility model is to provide a kind of collection valve and pipeline extension device function to be one, telescopic elastomeric valves simple in structure, easy to use.
The telescopic elastomeric valves of the utility model is to realize like this, it comprises valve body, the valve gap that cooperates with valve body, the gland that cooperates with valve gap, the spool that cooperates with body cavity, the valve rod that is connected with spool, the handwheel that is connected with valve rod is installed in the Sealing that respectively connects the cooperation place, the creeping flange that is arranged on the valve body termination and is slidingly matched with its endoporus, be installed in the seal ring of its cooperation place, and be arranged on the extension adjustment device between creeping flange and valve body.Wherein, creeping flange can be two, is connected to the valve body two ends, also can be one, is connected an end of valve body.Extension adjustment device is by the set screw nut that is fixed on by screw thread on the valve body, and an end and set screw nut central hole are slidingly matched, the adjustable lever that the T type groove on the other end and the creeping flange is slidingly matched, and form with the locking nut of adjustable lever two ends screw-thread fit.For guaranteeing that creeping flange is connected with the equilibrium of valve body, extension adjustment device generally should be three, be that three T type grooves are arranged on the creeping flange, equidistantly distribute on same circumference, set screw nut on the valve body also is three, corresponding one by one with T type groove, make the adjustable lever after the installation parallel with the creeping flange central axis.Because T type groove has certain-length, makes creeping flange can rotate adjusting in the several angle scope when mounted, is convenient to creeping flange and is connected with the external pipe flange.The flexible distance of creeping flange is by the central hole length decision of set screw nut.
The working principle of the telescopic elastomeric valves of the utility model is, during use, unscrew the locking nut at adjustable lever two ends, by the adjustable lever move left and right, regulate the distance between creeping flange and external pipe, creeping flange is just cooperated with the external pipe flange, and fix, screw locking nut simultaneously by connecting bolt.Realize pipeline and valve
The advantage of the telescopic elastomeric valves of the utility model is simple in structure, and collection valve and pipeline extension device function are one, and easy construction is reliable, is used for the water drainage-supply system pipe network, can reduce engineering cost.
Describe the utility model embodiment in detail below in conjunction with accompanying drawing.
Fig. 1: the utility model structural representation
Fig. 2: the A-A sectional view among Fig. 1
The telescopic elastomeric valves of the utility model comprises valve body 1, the valve gap 2 that cooperates with valve body 1, the gland 3 that cooperates with valve gap 2, the spool 4 that cooperates with valve body 1 inner chamber, the valve rod 5 that is connected with spool 4, the handwheel 6 that is connected with valve rod 5, be installed in the Sealing 7 of valve rod 5, valve gap 2 and gland 3 cooperation places, be arranged on valve body 1 termination and with the creeping flange 8 that its endoporus is slidingly matched, be installed in the seal ring 9 of its cooperation place, and the extension adjustment device that is arranged on 1 of creeping flange 8 and valve body.This extension adjustment device is by the set screw nut 10 that is fixed on by screw thread on the valve body 1, one end and set screw nut 10 central holes are slidingly matched, the adjustable lever 12 that T type groove 11 on the other end and the creeping flange 8 is slidingly matched, and form with the locking nut 13 of adjustable lever 12 two ends screw-thread fit.It is a that creeping flange 8 rotates the scope of regulating.
