Abstract
The utility model relates to a charge and discharge valve, which a charge and discharge valve particularly suitable for a medium pressure filling sealing butterfly valve disclosed by the patent with the patent number ZL 95230750.2. The charge and discharge valve is the bridge for the pressure of system medium and the medium pressure filling sealing butterfly valve. The charge and discharge valve comprises a stop valve, a one-way valve, two-position three-way liquid operated reversal valve, and a two-position three-way electric (manual) reversal valve. The utility model enables the medium pressure filling sealing butterfly valve to realize the two-way bearing, and the range of the application of the medium pressure filling sealing butterfly valve can be wider.
Description
The utility model relates to a kind of Charge and discharge valve, is applicable to that particularly the patent No. is the Charge and discharge valve of the disclosed a kind of medium pressurising seal butterfly valve of ZL95230750.2, and it is the bridge of system media pressure and medium pressurising seal butterfly valve.
In the prior art, medium pressurising seal butterfly valve can only bear uniaxial pressure, and actual conditions often requires the butterfly valve can bidirectional bearing, thereby makes the using scope of this butterfly valve narrower, is unfavorable for that the wide model of product is promoted.
The purpose of this utility model is in order to overcome above-mentioned shortcoming, and what propose a kind of pressurising that can guarantee medium pressurising seal butterfly valve bidirectional bearing or pressure release fills the system of letting out, i.e. Charge and discharge valve.
The purpose of this utility model is achieved in that
A kind of Charge and discharge valve, the newly-increased core component as medium pressurising seal butterfly valve is characterized in that:
1, described Charge and discharge valve has three extraneous ports, communicates with the hollow rubber seal of medium pressurising seal butterfly valve and the pressure-bearing side and the non-pressure-bearing side of valve by pipeline respectively, and wherein the O mouth communicates with hollow rubber seal, P
1Mouth and P
2Mouth communicates with the pressure-bearing side and the non-pressure-bearing side of valve respectively;
2, described Charge and discharge valve is a combination, comprise that two-bit triplet electricity (hand) moves selector valve, two-bit triplet hydraulicchange-over valve and one-way valve, all these component all get up by passage UNICOM, and the both UNICOM's formation combinations separately of described component, also can be integrated in one;
3, the circulating direction of described one-way valve is: by the pressurising seal ring toward MEDIA FLOW stylet direction for logical, by the MEDIA FLOW stylet till the pressurising seal ring direction.Wherein, described two-bit triplet hydraulicchange-over valve is made up of valve body and the spool that can move freely in valve body, and three main stem mouths and two byroad mouths are arranged respectively on the valve body; In use easy to maintenance for the utility model, the utility model can also increase stop valve.
The spool of hydraulicchange-over valve is not subjected to other external force, only promotes by the operating mode medium.Stop valve is often opened at ordinary times, closes when the maintenance Charge and discharge valve for general.
Because the utility model can make medium pressurising seal butterfly valve realize bidirectional bearing, thereby makes the application area of medium pressurising seal butterfly valve wider.
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described further
Fig. 1 is a working principle schematic representation of the present utility model;
Fig. 2 is the structural representation of two-bit triplet hydraulicchange-over valve of the present utility model.
As shown in Figure 1, be a preferred embodiment of the present utility model in the frame of broken lines among the figure, it comprises 3,4, one two-bit triplet hydraulicchange-over valves 5 of 1,2, two one-way valves of two stop valves and the moving selector valve 6 of a two-bit triplet electricity (hand).As shown in Figure 2, two-bit triplet hydraulicchange-over valve 5 is made up of the valve body (10) and the spool (11) that can move freely in valve body (10), and three main stem mouth (O are arranged respectively on the valve body (10)
