Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of marine engineering equipment hydraulic system protection, and relates to a valve box structure design applied to valve group protection in marine splash zone, which is especially suitable for valve groups with solenoid valves, proportional valves, servo valves, overflow valves, pressure reducing valves, sensors and other components containing electromagnets and electrical sensitive components. BACKGROUND

[0002] Due to the particularity of the marine splash zone environment, high corrosion and waterproof grades are required, and marine engineering has high requirements for equipment reliability, so the corrosion resistance, waterproof grade and use reliability of the valve group and the components thereon are all highly required.

[0003] In the prior art, paint spraying protection, the use of IP-grade components and the use of stainless steel to change the valve and valve block body material are adopted. Since the valve surface finish is not suitable for paint spraying, the adhesion of paint spraying is generally low, resulting in limited paint spraying protection life. In addition, solenoid valves, sensors and other components are not suitable for paint spraying, and the screw thread position of some pressure valves cannot be directly painted, so a considerable number of valves and sensors cannot be protected by paint spraying. The use of high IP-grade valves and sensors can generally meet the waterproof standard, but the corrosion resistance is limited, and high-cost methods such as the use of stainless steel are generally used, but the service life is generally limited, especially for non-metallic components, which significantly reduces the service life under the action of seawater and sunlight, and the cost is greatly increased. Therefore, the above-mentioned methods are not suitable for valve group protection in the marine splash zone. UTILITY MODEL CONTENTS

[0004] In view of the above problems of the prior art, the utility model aims to provide a valve box structure applied to valve group protection in the marine splash zone, which is applied to valve groups with solenoid valves, proportional valves, servo valves, overflow valves, pressure reducing valves and sensors, and has reliable structure sealing, convenient operation and adaptability to different valve group styles.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0006] A valve box applied to valve group protection in the marine splash zone, which comprises a valve box main body, a box cover, a transition plate and a seal therefor, and is characterized in that a box cover inclined brace and a box cover buffer and sealing structure are arranged between the valve box main body and the box cover; the transition plate connects the valve block and the valve box main body to reduce the valve box size and adapt to different valve block sizes; the valve box main body inner wall is provided with a plate with a cross hole to facilitate cable routing on the valve box inner wall; and the cable passes through the wall through an electrical wall joint to ensure waterproof sealing.

[0007] Further, the valve box main body and the box cover contact surface area structure is a plane or an inclined plane according to the valve group form, and the port forms a bent structure to improve the overall rigidity of the valve box.

[0008] Further, the heater is arranged in the box cover to ensure the temperature and dryness inside the valve box.

[0009] Further, the lock catch is arranged on the valve box body, and the lock catch is a spherical lock catch or an adjustable position self-locking lock catch to ensure that the valve box can be reliably locked within a certain deformation range; the valve box body and the box cover are hingedly connected, and the hinge adopts a self-lubricating bushing to reduce the maintenance requirement of the valve box.

[0010] Further, the large end face of the box cover is punched out as an X shape by using a stamping process to improve the rigidity of the box cover.

[0011] Further, the sealing structure between the valve box body and the box cover adopts a double sealing form to improve the sealing reliability; the buffer structure adopts a position-adjustable hard rubber block to compensate the influence of the deformation of the valve box and the box cover on the sealing and simultaneously reduce the impact when the box cover is closed.

[0012] By using the above technical scheme, the valve box structure for protecting the valve group in the marine splash zone is applied, when the box cover covers the valve box body, the special sealing structure, the bending part of which forms the first splash-proof seawater, then continues to form two seals through the internal sealing element, so as to reliably seal; the internal heater is heated to ensure that the temperature inside the valve box is always higher than the outside, avoiding the convection caused by the temperature change between the inside and the outside of the valve box, thereby significantly reducing the humidity and the salt fog degree inside the valve box, and improving the working environment of the internal valve group. The use of the special lock catch and the buffer function further ensure that the valve box can ensure reliable sealing in harsh working conditions. BRIEF DESCRIPTION OF DRAWINGS
