Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic valves, in particular to a hydraulic valve with good safety. Background Art

[0002] A hydraulic valve is a component that can be used to control the pressure, flow, and direction of a liquid. It is controlled by the pressure oil of a pressure-regulating valve and is usually used in combination with an electromagnetic pressure-regulating valve. It can be used to remotely control the on / off of oil, gas, and water pipeline systems in hydropower stations. It is often used for clamping, controlling, lubricating, and other oil circuits. When using a hydraulic valve, it is necessary to turn the switch handle outside the hydraulic valve to drive the switch shaft to rotate, thereby controlling the opening and closing of the valve.

[0003] However, during actual use, the switch handle outside the valve is easily rotated by the force of accidental contact, which will cause the switch shaft to rotate erroneously, affecting the use of the hydraulic valve and also affecting safety. Utility Model Content

[0004] (1) Technical problems solved

[0005] The technical problem to be solved by the present invention is that currently the switch handle can be turned directly, but this method of rotation is prone to cause the switch handle to be rotated incorrectly due to external force caused by erroneous operation, thereby affecting the switching and closing states of the hydraulic valve, which in turn affects safety.

[0006] (2) Technical solution

[0007] In order to solve the above technical problems, the technical solution provided by the utility model is: a hydraulic valve with good safety, including a hydraulic valve body, a switch shaft is provided in the hydraulic valve body, and also includes a detachable handle, a limiter and a connecting member arranged on the hydraulic valve body and cooperating with the switch shaft, the connecting member includes a connecting block cooperating with the switch shaft, a horizontal through groove and a vertical through groove are provided in the connecting block, the detachable handle includes a straight rod cooperating with the horizontal through groove, a through hole is provided in the straight rod cooperating with the vertical through groove, and the limiter includes an inserted rod cooperating with the vertical through groove and the through hole.

[0008] As an improvement, a grip block is fixed to the upper end of the insertion rod.

[0009] As an improvement, a magnetic sheet 1 is provided at the upper end of the connecting block around the vertical through slot, and a magnetic sheet 2 cooperating with the magnetic sheet 1 is provided at the lower end of the gripping block around the insertion rod.

[0010] As an improvement, one end of the straight rod is fixedly connected to a handle, and a non-slip rubber sleeve is sleeved on the handle.

[0011] As an improvement, the lower end of the hydraulic valve body is provided with oppositely arranged bases, and the bases on both sides are fixedly connected with limit plates that cooperate with the straight rod.

[0012] As an improvement, an anti-slip sheet is adhered to the surface of the grip block.

[0013] (3) Beneficial effects

[0014] The advantages of the present invention over the prior art are that: when there is no need to control the switch of the hydraulic valve body, the detachable handle is removed and temporarily stored in the space between the base and the limit plate; when control is needed, the switch shaft of the hydraulic valve body can be rotated by rotating the connecting piece; the detachable handle is connected to the connecting piece by the limit piece, and the straight rod can be rotated to drive the switch shaft to rotate, thereby controlling the switch; the detachable handle is temporarily stored when not in use to prevent the straight rod from being accidentally rotated by external force.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Example 1

[0023] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a hydraulic valve with good safety includes a hydraulic valve body 1, in which a switch shaft is provided, and further includes a detachable handle, a limit member and a connecting member provided on the hydraulic valve body 1 and cooperating with the switch shaft, the connecting member including a connecting block 4 cooperating with the switch shaft.

[0024] Through the above structure, the switch shaft can be controlled by rotating the connecting block 4, thereby controlling the switch of the hydraulic valve body 1. The specific structure of how to control the switch shaft is as follows:

[0025] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a transverse groove 5 and a vertical groove 6 are provided in the connecting block 4, and the detachable handle includes a straight rod 2 that cooperates with the transverse groove 5, and a grip 3 is fixedly connected to one end of the straight rod 2, and a non-slip rubber sleeve is sleeved on the grip 3. A through hole 10 that cooperates with the vertical groove 6 is provided in the straight rod 2, and the limiting member includes an insertion rod 9 that cooperates with the vertical groove 6 and the through hole 10. The upper end of the insertion rod 9 is fixed with a grip block 13, and a non-slip sheet is adhered to the surface of the grip block 13 for easy gripping of the grip block 13. The upper end of the connecting block 4 is provided with a magnetic sheet 7 around the vertical groove 6, and the lower end of the grip block 13 is provided with a magnetic sheet 8 that cooperates with the magnetic sheet 7 around the insertion rod 9. The grip block 13 can be adsorbed on the upper end of the connecting block 4 by magnetic attraction.

[0026] With the above structure, the detachable handle is mounted on the connecting piece, and the straight rod 2 can be rotated to control the switch shaft.

[0027] Example 2

[0028] like Figure 5 As shown, the lower end of the hydraulic valve body 1 is provided with oppositely arranged bases 11 , and limiting plates 12 cooperating with the straight rod 2 are fixedly connected to the bases 11 on both sides.

[0029] The above structure makes it convenient to temporarily store the detachable turning handle when it is not in use.

[0030] When the utility model is implemented, when it is necessary to control the switch of the hydraulic valve body, specifically, take out the straight rod and insert the straight rod into the horizontal groove until the through hole on the straight rod is aligned with the vertical groove. At this time, grasp the grip block and pass the insertion rod through the vertical groove and the through hole. In this way, the straight rod can be limited in the horizontal groove. A magnetic attraction force will be generated between the magnetic piece 2 at the lower end of the grip block and the magnetic piece 1 at the upper end of the connecting block. The magnetic attraction force can be used to adsorb the grip block to the upper end of the connecting block. When the detachable turning handle is not in use, remove the connecting piece and the detachable turning handle, and place the straight rod in the space between the limit plate and the base to temporarily store the detachable turning handle, so as to avoid the straight rod being accidentally pushed by external force when the switch of the hydraulic valve body is not needed.
