Description

Novel differential pressure valve
Technical Field
The utility model relates to a valve field especially relates to a novel differential pressure valve.
Background
The differential pressure valve adjusts the opening of the valve by the differential pressure effect, and compensates the change of the pipeline resistance by the pressure drop change of the valve core, thereby keeping the differential pressure basically unchanged when the working condition changes.
The chinese utility model patent with publication number CN211259782U discloses a dynamic differential pressure valve, which comprises a valve body, a valve seat, a cage-type sleeve, a pressure sensing membrane assembly, a dynamic valve core, a spring, a top cover, a cross pressure regulating body and a pressure regulating screw; the valve seat is arranged in the valve body; the cage type sleeve is fixedly connected in the valve body; the pressure sensing membrane assembly is arranged in the cage type sleeve; the dynamic valve core is arranged in the cage type sleeve and corresponds to the valve seat up and down; the spring is supported between the valve seat and the dynamic valve core; the top cover is arranged on the opening at the top of the valve body; the cross pressure regulating body is vertically provided with drainage holes which are communicated with the upper space of the pressure sensing membrane assembly; a mixing cavity is formed between the top cover and the upper part of the pressure sensing membrane assembly, and a low-pressure cavity is formed between the valve seat and the water inlet; the cross pressure regulating body is connected with a communicating pipe which is communicated with the drainage hole and the low pressure cavity; the pressure regulating screw is in threaded connection with the cross pressure regulating body, and the small end of the pressure regulating screw corresponds to the opening of the communicating pipe, so that the pressure difference at two ends of the controlled system can be conveniently regulated.
However, the differential pressure valve is not stable enough in structure, poor in durability, high in replacement frequency after long-term use and high in use cost of users.
SUMMERY OF THE UTILITY MODEL
In order to overcome the not enough of above-mentioned prior art, the utility model provides a novel differential pressure valve for solve prior art medium-pressure differential valve structure stable inadequately, use the poor problem of durability.
The utility model adopts the technical proposal that: the utility model provides a novel differential pressure valve, includes valve body, lower apron, case, baffle, upper cover plate, rotatory handle, the one end of apron is installed in the valve body for circular cavity down, the case is installed in the circular cavity, the valve plate is fixed under on the apron, the upper cover plate passes through the screw the valve plate with apron locking down.
Preferably, a sealing sleeve is arranged at the upper end of the upper cover plate, an upper cover sealing head is arranged above the sealing sleeve, and a rotating handle is mounted on the upper cover sealing head.
Preferably, the upper portion of lower apron is provided with the strengthening rib along circumference, follows the strengthening rib circumference interval is provided with a plurality of screw mounting holes.
Preferably, the rotating handle comprises a rotating head and a sleeve head, the rotating head is provided with anti-skidding threads, a sliding groove is formed in the sleeve head, and a convex strip is arranged at the upper end of the upper cover sealing head.
Preferably, the sleeve head is provided with scales.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses differential pressure valve compares with prior art, and the structure is more stable, possesses better leakproofness, and the simple operation is fixed with the spout cooperation in the pullover through the sand grip of upper cover head, uses the durability higher.
Drawings
Fig. 1 is a schematic view of the overall structure of a novel differential pressure valve according to the present invention;
FIG. 2 is an explosion diagram of a novel differential pressure valve
FIG. 3 is a partial enlarged view of a novel differential pressure valve
The valve comprises a valve body 1, a valve body 2, a lower cover plate 3, a valve plate 4, a valve core 5, an upper cover plate 6, a rotary handle 7, a sealing sleeve 8, an upper cover sealing head 9, a sliding groove 10, a convex strip 11, an anti-skid thread 12, scales 13, a sleeve head 14 and reinforcing ribs.
Detailed Description
The present invention will be further described in detail with reference to the following specific examples:
referring to fig. 1-3, the utility model provides a pair of novel differential pressure valve includes valve body 1, lower apron 2, valve plate 3, case 4, rotatory handle 6, wherein the below of apron 2 is an annular cavity down, annular cavity is placed in the valve body 1, case 4 is installed in the annular cavity, and move in the annular cavity, and then drive the work of whole differential pressure valve.
Lower apron 2's top is provided with strengthening rib 14, is used for increasing apron 2's intensity down, at the even a plurality of screw hole of having arranged of a week of strengthening rib 14, the screw hole upwards passes valve plate 3, with upper cover plate 2 locks, can make overall structure more stable through set up the screw hole in strengthening rib 14 circumference.
The valve plate 3 is of an annular structure and is fixedly installed between the upper cover plate 5 and the lower cover plate 2, a sealing sleeve 7 is arranged on the upper cover plate 5, an upper cover end socket 8 is fixedly installed on the upper portion of the sealing sleeve 7, and 2 convex strips 10 are arranged on the upper cover end socket 8; 2 spout 9 have been seted up to the sand grip 10 that matches the upper cover head in pullover 13, when rotatory handle 7 suit down on the upper cover head 8 is time-consuming, 2 sand grips 10 on the upper cover head are drawn into in 2 spout 9 in pullover 13, through spout 9 with the cooperation of sand grip 10 can make rotatory handle 6 with upper cover head 8 is fixed together, adopts the cooperation simple structure of spout and sand grip, and it is more stable to use, be provided with a plurality of anti-skidding screw threads on rotatory handle 6 for it is difficult to smooth when manual operation overlap and still be provided with scale 12 on the pullover 8, convenient observation, the differential pressure valve that adopts this kind of mode is structural more stable, and it is also longer to use the durability.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention.
