Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the following further describes the technical solution of the present invention with reference to the drawings and the embodiments.

Referring to fig. 1 to 4, the push type valve includes a valve body 1 having an inlet 101 and an outlet 101 at both ends thereof in sequence, a push pointer 11 selectively penetrating and blocking the inlet 101 and the outlet 102 is provided on the valve body 1, a control handle 12 for driving the push pointer 11 is hinged to the valve body 1, the push pointer 11 is pressed downward by a downward driving force of the control handle 12, and a ball and a spring (both not shown in the figure) in the valve body 1 are pressed at the same time, so that the inlet 101 and the outlet 102 are penetrated, and a valve opening operation is realized. After the external force applied to the control handle 12 is removed, the spring jacks up the ball body through the elastic force, and then the inlet 101 and the outlet 102 are blocked, so that the valve closing operation is realized.

In order to avoid the problem that the control handle 12 generates a driving force to press the pressing pointer 11 under the action of an external force to open the valve when the valve is not needed, as shown in fig. 1-2, a limiting device for limiting the control handle 12 to drive the pressing pointer 11 is arranged on the valve body 1, and the limiting device comprises a limiting mechanism which is in contact with and separated from the control handle 12. The limiting device is arranged on the valve body 1 and fixed, the limiting mechanism is in contact with or separated from the control handle 12, and under the contact action, the limiting mechanism limits the sliding of the control handle 12, so that the defect that the control handle 12 is extruded and pressed by external force to press the pointer 11 is overcome. When the valve opening operation is normally needed, the limiting mechanism is separated from the control handle 12, so that the control handle 12 can be driven by proper external force, and the accurate valve opening operation is realized, thereby effectively avoiding potential safety hazards caused by misoperation of the control handle 12.

Specifically, as shown in fig. 1-2, the limiting device includes a supporting post 2 disposed on the valve body 1, the limiting mechanism is a limiting block 3 rotatably disposed at a top end of the supporting post 2, a U-shaped groove 301 is horizontally and correspondingly disposed in the limiting block 3 toward a side wall of the control handle 12, and the control handle 12 can be selectively inserted into or separated from the U-shaped groove 301 under the rotation action of the limiting block 3. Under the supporting action of the supporting column 2, the U-shaped groove 301 of the limiting block 3 is horizontally corresponding to the side wall of the control handle 12, when the control handle 12 needs to be limited, the limiting block 3 is rotated, the U-shaped groove 301 is horizontally clamped on the upper surface, the lower surface and the side wall of the control handle 12, the control handle 12 is limited to rotate up and down, and misoperation caused by pressing the pointer 11 is avoided. When normal operation is needed, the limiting block 3 is rotated, so that the control handle 12 is separated from the U-shaped groove 301 to limit the U-shaped groove, and normal pressing and valve opening operation can be realized.

In order to avoid the problem that the control handle 12 still has a moving stroke due to the sleeve clearance between the U-shaped groove 301 and the control handle 12, as shown in fig. 3, both the upper and lower side surfaces of the U-shaped groove 301 are set to be inclined structures from the port parts thereof to the inner bottom surface direction (as shown in a in fig. 3, the upper and lower inclined surfaces form a conical structure of the inner cavity of the U-shaped groove 301). When the limiting block 3 rotates to clamp the control handle 12 into the U-shaped groove 301, the upper surface and the lower surface of the control handle 12 gradually abut against the upper side surface and the lower side surface of the U-shaped groove 301, so that the clamping state of the control handle and the U-shaped groove is realized, the fit clearance between the control handle and the U-shaped groove is eliminated, the problem that the control handle 12 still has a certain movable clearance after being limited is effectively solved, and the defect that the valve body 1 leaks under the action of external force is overcome.

In order to avoid the disadvantage that the control handle 12 is separated from the U-shaped groove 301 under the action of external force, as shown in fig. 3, a driving device for driving the control handle 12 to be clamped in the U-shaped groove 301 is arranged on the limiting block 3. The driving device can clamp the control handle 12 in the U-shaped groove 301 and overcome the defect that the control handle and the U-shaped groove are separated from each other due to the action of external force.

Specifically, as shown in fig. 4, the driving device is a fastening screw 4 penetrating through the side wall of the limiting block 3 and extending into the U-shaped groove 301, a fastening hole 12a matching with the fastening screw 4 is formed in the side wall of the control handle 12, and a penetrating hole 302 larger than the fastening screw 4 is formed in the limiting block 3. After the control handle 12 is tightly matched with the U-shaped groove 301, the fastening screw 4 is arranged in the fastening hole 12a in a penetrating mode, the control handle 12 is connected and fastened with the limiting block 3, and the problem that the control handle 12 and the limiting block are separated from each other due to external force is solved. The through hole 302 formed in the limiting block 3 is larger than the fastening screw 4 (outer diameter), so as to avoid the disadvantage that the limiting block 3 interferes with the corresponding connection of the fastening screw 4 and the fastening hole 12a in the arc-shaped rotating process.

Preferably, in order to avoid the problem that the control handle 12 is not limited by the limiting block 3, and the fastening screw 4 is not separated from the through hole 302, so that the fastening screw is lost, an anti-lost rope 6 is rotatably connected to the end of the fastening screw 4, and the other end of the anti-lost rope 6 is fixed on the outer wall of the limiting block 3, so that the problem that the fastening screw 4 is lost can be effectively avoided.

In order to enable the upper surface and the lower surface of the control handle 12 to simultaneously contact the upper surface and the lower surface of the U-shaped groove 301, the bottom end of the support column 2 is threaded in the valve body 1, and the bottom end of the support column 2 is sleeved with a limiting nut 5 for limiting the extending height of the support column. The vertical height of the limiting block 3 can be adjusted by rotating the supporting column 2, and then the U-shaped groove 301 of the limiting block is adjusted to be horizontally corresponding to the control handle 12, so that the problem that the limiting block presses down or lifts the control handle 12 due to vertical deviation is avoided. After the adjustment is completed, the support column 2 is locked by screwing the limit nut 5 and contacting the upper surface of the valve body 1.

The principle of the utility model is as follows: the valve body 1 is provided with the limiting block 3 rotatably arranged at the top end of the support column 2, the limiting block 3 can tightly clamp the control handle 12 in the U-shaped groove 301 when rotating, the limiting block 3 and the control handle 12 are tightened through the fastening screw rod 4, the limiting effect on the control handle 12 is realized, the misoperation caused by pressing the pointer 11 by the control handle 12 due to the action of external force is avoided, and the problems of leakage and potential safety hazard of the valve body 1 are further solved. When normal valve opening operation is required, the tightening action of the fastening screw rod 4 is loosened, the limiting block 3 is rotated, the limitation on the control handle 12 is removed, and normal valve opening operation is realized.

The foregoing shows and describes the general principles, essential features, and advantages of the utility model.
