Abstract
The utility model discloses a constant pressure water valve, which comprises a valve body and a valve seat, wherein, a constant pressure adjusting screw and a nut are arranged on the upper part of the valve body. The outer ring of the nut is provided with a graduated disk. The bottom in the valve seat is fixed with a test coil, the lower end of a test rod is arranged in the middle of the test coil, and the upper end of the test rod is connected with a linking valve core. A pressure adjusting spring is arranged on the top surface of the linking valve core. The outer side of the bottom of the valve seat is fixed with a sealing waterproof socket. The utility model has the advantages of simple structure, low cost, convenient installation and operation, and constant water supply pressure.
Description
The utility model relates to a kind of valve, and particularly a kind of constant voltage is crossed water valve.
Along with the development of industrial and agricultural production, often need carry out constant pressure water supply at present, but method is comparatively complicated mostly, the cost height.When carrying out constant pressure water supply such as the employing pneumatic installation water supply, pump and switch are usually owing to frequent starting damages.
The purpose of this utility model just is that the constant voltage that provides a kind of cheap, easy for installation crosses water valve.
Technical solution of the present utility model is: constant voltage is set on the top of valve body adjusts screw and the nut supporting with it, in the outer ring of nut scale is set; Bottom in the valve seat is fixed with Test coil, is provided with test rod in the centre of Test coil, and the upper end of test rod is the interlock spool, pressure adjusting spring be arranged on the interlock spool above, the bottom outside of valve seat is fixed with the water-tight socket.
The utility model is simple in structure, and is with low cost, easy to install, can be widely used in the water supply system, can realize the purpose of constant pressure water supply, again can be with water amount by instrument record, control.
Fig. 1 is a structure sectional plan view of the present utility model.
Fig. 2 is the schematic representation that the utility model is used in system.
Embodiment is as follows: with reference to accompanying drawing, but the top of valve body 1 is provided with the nut 10 that constant voltage is adjusted screw 3 and the self-locking supporting with it, is provided with dial 2 in the outer ring of nut 10; Bottom in the valve seat 9 is fixed with Test coil 5, the upper end of test rod 4 is connected as a single entity with interlock spool 7, the lower end place Test coil 5 the centre and can upper and lowerly be free to slide, pressure adjusting spring 8 be arranged on the interlock spool 7 above, the bottom outside of valve seat 9 is fixed with water-tight socket 6.When water entered water valve, promote interlock spool 7 and move upward; Owing to be subjected to the back-pressure effect of pressure adjusting spring 8, the positioning control that makes interlock spool 7 is in certain aperture; Test rod 4 was driven also and was moved up this moment, and Test coil 5 sends the variation of this displacement amount to instrument by water-tight socket 6 and goes record, control etc.
Fig. 2 uses schematic representation for the utility model in system.Water is supplied with to the B place by water pump G by the A place, and when hydraulic pressure reached setting value, constant voltage was crossed water valve E and opened, and water is back to the F place by the C place by filter D, makes the pressure at B place keep constant.
