Embodiment 1

[0037] Cooperating with manual shut-off valve and electric shut-off valve:

[0038] like Figure 5 As shown, two communicating accommodation grooves 103 are set on the valve body 1, the first passage 101 communicates with the bottom of one accommodation groove 103, the second passage 102 communicates with the side wall of the other accommodation groove 103, and the accommodation groove 103 on the valve body 1 covers It is located outside the packing 201, the packing gland 202 is pressed and set on the upper end of the packing 201, the pressure plate 203 is fastened and set on the upper part of the packing gland 202, the pressure plate 203 is detachably installed on the valve body 1 through bolts, and the stop valve spool is worn on the The center position of the pressure plate 203, the packing gland 202 and the packing 201. The valve core of the stop valve includes a valve seat, a gland, a valve stem and a key. The rod is slidably connected to the pressure sleeve, and the pre...

Embodiment 2

[0040] Cooperate with manual stop valve and electric throttle valve:

[0041] like Image 6 As shown, the installation of the manual shut-off valve is the same as that in Embodiment 1. In another accommodation groove 103, the accommodation groove 103 is sleeved on the outside of the packing 201, the packing gland 202 is pressed on the upper end of the packing 201, and the pressure plate 203 is fastened on the packing. On the upper part of the pressure sleeve 202, the pressure plate 203 is detachably installed on the valve body 1 through bolts. The throttle valve core is set at the center of the pressure plate 203, the packing pressure sleeve 202 and the packing 201. The throttle valve core includes a valve seat, a pressure sleeve , the key and the bottom are valve stems with a conical structure, the valve seat is arranged at the bottom of the accommodation groove 103, the valve stem is slidingly connected with the pressure sleeve, and the pressure sleeve is provided with evenl...

Embodiment 3

[0043] Cooperate with manual shut-off valve and electric regulating valve

[0044] like Figure 7 As shown, the installation of the manual shut-off valve is the same as that in Embodiment 1. In another accommodation groove 103, the accommodation groove 103 is sleeved on the outside of the packing 201, the packing gland 202 is pressed on the upper end of the packing 201, and the pressure plate 203 is fastened on the packing. On the upper part of the pressure sleeve 202, the pressure plate 203 is detachably installed on the valve body 1 through bolts. The regulating valve spool is set at the center of the pressure plate 203, the packing pressure sleeve 202 and the packing 201. The regulating valve spool includes a valve seat, a pressure sleeve, and a key. And the valve stem, the valve seat and the pressure sleeve are all provided with uniformly distributed holes, the valve seat is arranged at the bottom of the accommodation groove 103, the pressure sleeve is set at the lower end...

Abstract

The invention relates to the field of valves, in particular to a modular combined valve base frame and a valve. The modular combined valve base frame comprises a valve body with multiple containing grooves. A first channel and a second channel are formed in the valve body. The first channel, the containing grooves of the valve body and the second channel sequentially communicate with one another.A sealing unit is detachably arranged at the upper portion of each containing groove, and the lower portion of each sealing unit is detachably connected with the valve body. Execution units are detachably arranged at the upper portions of the sealing units, and each execution unit, the corresponding sealing unit and the valve body form a containing cavity for containing a valve element. Compared with the prior art, the modular combined valve base frame has the beneficial effects that through the modular design, corresponding combination functions can still be achieved through a simple method of replacing the internal valve element after the valve body is welded, space is reserved for system optimization and upgrading, the system optimization and upgrading cost is reduced, the modular structure is easy to maintain, maintenance time is effectively shortened, maintenance cost is saved, inventory can be reduced, and production and management cost is reduced.

Description

technical field [0001] The invention relates to the field of valves, in particular to a modular combined valve base frame and a valve. Background technique [0002] At present, in the power plant boiler system and steam turbine system, two valves with the same diameter are often used in series in the same pipeline. The warm water pipeline uses a shut-off valve normally open and a throttling valve in series for flow adjustment; or a shut-off valve and a check valve are used in series to control the on-off of the medium and prevent the backflow of the medium. Existing valves cannot meet their changing functional requirements, and the existing series use scheme has a single function, and there is no room for performance improvement. For example, in the construction of pipelines, manual function valves are used in consideration of economic factors. In the later stage, manual valves are upgraded to electric valves in order to realize automatic control. It is necessary to make ma...
