Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of container valve, concretely relates to a gas cylinder container valve. BACKGROUND

[0002] There are many kinds of container valves for gas fire extinguishing agent cylinders, which are divided into electric automatic starting, electric manual starting and mechanical emergency starting according to the starting mode; and are divided into diaphragm sealing type and piston sealing type according to the sealing mode; in the fluid control system, the valve as a key component, its stability and operation convenience are crucial to the normal operation of the system.

[0003] The valve handle as the main component of operating the valve, its design directly affects the control accuracy and use experience of the valve. The traditional valve handle design often faces the problem of loosening or angle change under external force, which not only affects the sealing performance of the valve, but also may cause the fluid control system to malfunction, and even cause safety accidents. UTILITY MODEL CONTENTS

[0004] The utility model aims at providing a gas cylinder container valve to solve the problem of loosening or angle change of the valve handle under external force in the prior art.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] A gas cylinder container valve, comprising a valve body, one side of the valve body is fixed with a hexagonal head, the hexagonal head is rotationally connected with a valve handle, a plurality of recessed ends are equidistantly distributed around the valve handle; a pressing mechanism is used to press the recessed end of the valve handle.

[0007] Further, the pressing mechanism comprises a positioning ring, the positioning ring is arranged on the hexagonal head, a plurality of support plates equal to the number of recessed ends are equidistantly distributed on the positioning ring, the top end of the support plate is provided with a pressing head, and the pressing head is matched with the recessed end.

[0008] Further, the pressing mechanism is integrally formed by using plastic material, and each support plate is inclined to the inner diameter of the positioning ring.

[0009] Further, the surface of the recessed end is smooth and transitions to a semicircular shape, one side of the pressing head has a contact surface in contact with the recessed end, and the contact surface is smooth and transitions.

[0010] Further, the valve handle is also equidistantly distributed with a convex end, the part where the convex end and the contact surface contact is embedded with a ball. When the valve handle is rotated, the convex end will contact the contact surface, and the ball embedded on the surface of the contact surface can help the valve handle to rotate, change the sliding friction into rolling friction, further improve the use interaction of the valve handle, and make the recessed end on the valve handle return to the pressing head.

[0011] Furthermore, the positioning ring and the outer wall of the support plate are provided with external threads, and a clamping nut is threaded onto the external threads. The outer wall of the clamping nut is provided with a force-bearing rod.

[0012] The technical solution of this utility model has the following beneficial effects:

[0013] 1. The clamping head and the recessed end cooperate with each other. Because each support plate is inclined towards the inner diameter of the positioning ring, the clamping head will apply some pressure evenly distributed on the recessed end to prevent the valve handle from becoming loose or the valve handle angle from changing due to external force collision. At the same time, the pressure applied by the clamping head can improve the interactivity of the valve handle. When the user rotates the valve handle, a slight resistance will be generated, thereby improving the feel of the valve handle. The overall structure is simple, easy to manufacture and reduces production costs.

[0014] 2. The tightness of the clamping head can also be changed by adjusting the position of the clamping nut, which can be either slight or full. Full tightness means that the valve handle is difficult to turn, while slight tightness increases the clamping resistance of the valve handle. The resistance can be increased according to the usage requirements. Attached Figure Description

Detailed Implementation

[0021] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model will be described in further detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and are not used to limit the utility model. Based on the examples in the utility model, all other examples obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0022] Example one:

[0023] Reference Figure 1 A gas cylinder container valve, including valve body 10, one side of valve body 10 is fixed with hex head 13, hex head 13 is rotatably connected with valve handle 14, and input end 11 and output end 12 are respectively arranged at both ends of valve body 10.

[0024] In the above scheme, input end 11 is used to connect the output port of the gas cylinder, and output end 12 on valve body 10 is used to output the gas in the cylinder; valve body 10 is provided with a capacity meter and a pressure gauge for monitoring the gas capacity and pressure in the cylinder; valve handle 14 is used to rotate to control the medium flow or adjust the medium pressure, and it should be noted that: valve body 10 has a corresponding valve mechanism inside, and the rotation of valve handle 14 is used to realize opening and closing, which is a conventional use means of the prior art, and will not be described in detail.

[0025] Reference Figures 1-3 A plurality of concave ends 15 are equidistantly distributed around valve handle 14; a pressing mechanism is used to press the concave end 15 at valve handle 14.

[0026] The pressing mechanism comprises a positioning ring 201, the positioning ring 201 is arranged on the hex head 13, and a plurality of support plates 202 equal to the number of concave ends 15 are equidistantly distributed on the positioning ring 201, the top end of the support plate 202 is provided with a pressing head 203, and the pressing head 203 cooperates with the concave end 15.

[0027] The pressing mechanism is integrally formed by using plastic material, and each support plate 202 is inclined to the inner diameter of the positioning ring 201.

[0028] In the above scheme, the positioning ring 201 is fixedly connected with the hexagonal head 13, and the pressing head 203 is matched with the recessed end 15. Since each support plate 202 is inclined to the inner diameter of the positioning ring 201, the pressing head 203 will exert some pressure uniformly distributed on the recessed end 15, so as to avoid the problem of loosening of the valve handle 14 or change of the angle of the valve handle 14 caused by external force impact. At the same time, the pressure exerted by the pressing head 203 can improve the use interaction of the valve handle 14. When the user rotates the valve handle 14, a small amount of resistance will be generated, thereby improving the use feeling of the valve handle 14. The pressure provided by the pressing head 203 means that a certain force is needed to rotate the valve handle 14. The overall structure is simple, easy to produce and can reduce production cost.

[0029] The plastic material can be selected from plastic materials with toughness, such as PC, PE, PA, etc., which can withstand deformation.

[0030] Further reference Figure 1 and Figure 3 The surface of the recessed end 15 is smooth and transitions to a semi-elliptical shape. The pressing head 203 has a contact surface 204 on one side which is in contact with the recessed end 15. The contact surface 204 is smooth and transitions.

[0031] In a further embodiment, the smooth transition of the contact surface 204 and the recessed end 15 can reduce the static friction therebetween, thereby avoiding the problem that the valve handle 14 is too tightly pressed by the pressing head 203 and is difficult to rotate.

[0032] Example two:

[0033] Reference Figure 4 The valve handle 14 also has a protruding end 16 which is equally distributed. The part where the protruding end 16 is in contact with the contact surface 204 is embedded with a ball 17. The ball 17 can rotate freely.

[0034] In the above scheme, when the valve handle 14 is rotated, the protruding end 16 will contact the contact surface 204, and the ball 17 embedded on the surface of the contact surface 204 can help the valve handle 14 to rotate, changing the sliding friction to rolling friction, further improving the use interaction of the valve handle 14, and enabling the recessed end 15 on the valve handle 14 to return to the pressing head 203.

[0035] Example three:

[0036] Reference Figure 2 The positioning ring 201 and the outer wall of the support plate 202 are provided with external threads 205. The external threads 205 are threadedly engaged with a pressing nut 30, and the outer wall of the pressing nut 30 is provided with a force receiving rod 301.

[0037] In the above scheme, the pressing head 203 contacts the recessed end 15, and the recessed end 15 will push the pressing head 203 outward to expand.

[0038] When the clamping nut 30 is on the outer wall of the positioning ring 201 and not on the outer wall of the support plate 202, the deformation elasticity of the support plate 202 is not affected and remains consistent with the pressure applied in Embodiment 1. When the clamping nut 30 is rotated between the outer wall of the positioning ring 201 and the outer wall of the support plate 202, the clamping head 203 will push outward and expand due to contact with the recessed end 15. The clamping nut 30 will apply an inward pressure to make the support plate 202 move inward, thereby pressing the clamping head 203 into the recessed end 15. By rotating to control the position of the clamping nut 30, the degree of clamping of the clamping mechanism on the valve handle 14 can be changed.

[0039] At the same time, the clamping degree of the clamping head 203 can also be changed by adjusting the position of the clamping nut 30, which can be manifested as slight clamping or full clamping. Full clamping means that the valve handle 14 is difficult to turn, while slight clamping means that the clamping resistance of the valve handle 14 is increased, and the operating resistance is increased according to the usage needs.

[0040] The force-bearing rod 301 allows for easy rotation to tighten the clamping nut 30.

[0041] The specific implementation process of this utility model is as follows:

[0042] The clamping head 203 cooperates with the recessed end 15. Since each support plate 202 is inclined towards the inner diameter of the positioning ring 201, the clamping head 203 will apply some pressure evenly distributed on the recessed end 15 to avoid the valve handle 14 from becoming loose or the valve handle 14 changing its angle due to external force collision.

[0043] The clamping degree of the clamping head 203 can also be changed by adjusting the position of the clamping nut 30, which can be manifested as slight clamping or full clamping. Full clamping means that the valve handle 14 cannot be rotated, while slight clamping means that the clamping resistance of the valve handle 14 is increased.

[0044] The above embodiments are merely exemplary models of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Various modifications or equivalent substitutions can be made to this utility model within its substance and scope of protection.
