Abstract
The utility model relates to a diaphragm-brake type control valve which comprises a valve body. A double chamber diaphragm-type brake is installed on the valve body. The brake is composed of a lower seat of the brake, an upper cover of the brake, a braking diaphragm, a diaphragm clamping plate, a valve rod, a sealing mechanism which is mated with a sealing bearing port of the valve body. Control interfaces are arranged both on the brake and an import and an export of the valve body. The utility model has the advantages of compact structure, reliable seal, no leakage, small flow resistance, and flexible on-off. The hydraulic control principle is used, different guide control devices are combined, without outside power source, and different automatic control functions can be realized.
Description
The utility model belongs to a kind of valve, relates in particular to the control valve that a kind of water system is used.
At present, widely used water supply valve in water system, the ubiquity resistance to water-flow is big, and is poorly sealed, opens, closes effort, and can't carry out long-distance remote control and control automatically, more can't make a kind of valve have many shortcomings of various control function.
The purpose of this utility model provides a kind of water supply valve flexible and that can carry out guide's control that seals reliably, opens and closes.
For reaching above-mentioned purpose, the utility model by the following technical solutions:
A kind of diaphragm break formula control valve, comprise valve body, two chambers diaphragm type break is installed on the valve body, break is made up of following of break, break loam cake, braking diaphragm, diaphragm clamping plate, valve rod and the sealing mechanism that cooperates with the valve seal bellmouth, braking diaphragm periphery is by a break loam cake and a following clamping, the center is fixed on the valve rod with locking nut by the diaphragm clamping plate, with between following of the sealing sealing mechanism that cooperates of bellmouth and break spring is housed, break is connected with valve body with bolt, and the entrance end with valve body on the break all has control interface.
The described sealing mechanism that cooperates with the sealing bellmouth is made up of platen about diaphragm seal, the diaphragm seal, and diaphragm seal platen up and down connects by bolt, and sealing mechanism is fixedlyed connected with valve rod by locking nut.
The shape approximation of valve body is Y type, T type or L type.
Because the utility model is equipped with the diaphragm type break on valve body, form the control room between the loam cake of break and following and be divided into two-part up and down, realize valve opening and closing and control purpose flexibly thereby diaphragm is moved up and down together with valve rod by the guide's control gear control that is connected with control interface by diaphragm.The sealing mechanism that cooperates with the valve seal bellmouth can be pressed on the sealing bellmouth under the control of control gear, makes valve closing reliable.Because the utility model is to be opened and closed by the control of guide's control gear, moving element is located at valve inner, therefore has good seal, leak free advantage.The utility model is according to the hydraulic control principle, with different guide's control gear combinations, need not external power source, can form the automatic water-supply control valve of different purposes such as flow control valve, fluid level control valve door, pipeline burst automatic-closing valve, Safety valve, pressure regulating valve, check valve.By remote control guide control gear is installed, can realize remote electronic or hydraulicefficiency telecontrol.
Further specify the utility model below in conjunction with accompanying drawing and by embodiment:
Fig. 1 is embodiment 1 a structural representation;
Fig. 2 is embodiment 2 a structural representation;
Fig. 3 is embodiment 3 a structural representation;
Fig. 4 is the schematic representation that the utility model and manual pilot valve are formed manual control valve;
Fig. 5 is the schematic representation that the utility model and electromagnetic priority valve are formed the electromagnetism remote control valve.
Embodiment 1: be fixed with the diaphragm break with bolt 5 on the valve body 10 that is approximately the Y type, break is made up of loam cake 1, following 15, diaphragm 3, diaphragm punch holder 2, diaphragm die holder 4, valve rod 6 and the sealing mechanism that cooperates with the valve seal bellmouth, and sealing mechanism comprises platen 7 on diaphragm seal 8, the diaphragm seal, time platen 9.Loam cake 1 tightens up by bolt 14 with following 15, and diaphragm 3 peripheries are by a loam cake and a following clamping, and diaphragm 3 centers are contained on the valve rod 5, and it are tightened up by die holder on the diaphragm by locking nut 17.The upper and lower platen of diaphragm seal is fastened by bolt and diaphragm seal is tightened up, and platen 7 usefulness locking nuts 11 are fastened on the valve rod on the diaphragm seal.7 of platens are equipped with spring 13 on following 15 on break and diaphragm seal, cooperate guide's control gear to make the sealing bellmouth sealing of diaphragm seal and valve body tight, guarantee to close reliable.The entrance end of valve body is provided with control interface 12.Break is provided with control interface 16.
Embodiment 2: just the valve body shape approximation is the T type, and structure is identical with embodiment 1.
Embodiment 3: just the valve body shape approximation is the L type, and structure is identical with embodiment 1.
Manual pilot valve 18 shown in Figure 4 is connected on the control interface of the present utility model by pipeline forms manual control valve.
Solenoid valve 19 shown in Figure 5 is connected on by pipeline forms the electromagnetism remote control valve on the control interface of the present utility model.Other control modes no longer illustrate.
Claims (5)
