Abstract
The utility model belongs to the technical field of relief valves, and discloses a safety relief valve, which comprises a slideway which is provided with a window at the side, and a push and pull rod with a serrate surface, which is arranged at the side of the window, penetrates through the slideway; a supporting frame is arranged on the slideway, and one end of the slideway, which is a clamping strip used for inserting in a tooth groove on the serrate surface, is movably connected with a supporting frame; the movable connection position is provided with a control spring; and a moving control mechanism of the control spring is arranged on the clamping strip. The safety relief valve solves the problem that the failures are easy to bring about due to the existence of a certain moving displacement and the easy uncontrollability after the current relief valve is locked during using.
Description
Technical field
The utility model belongs to the relief valve technical field, relates to a kind of safety lock valve concretely.
Background technique
Relief valve uses the active connection place with various machineries, is used to control the activity displacement with solid mechanical.The relief valve that comparatively generally uses mostly is air spring mechanism at present, because air spring structural reason, in use also exist certain movable displacement amount after the locking, and this air spring also exists and easily takes off control, and the defective that the mechanical structure that causes institute to control and fix causes the accident because of dislocation.
The model utility content
The purpose of this utility model just provides a kind of safe and reliable relief valve.
To achieve these goals, the technological scheme that the utility model adopted is:
A kind of safety lock valve, include the slideway that the side has window, the pull bar that the side that is in the window place is provided with serrated face is through at wherein, described slideway is provided with supporting frame, card article and described supporting frame that the one end is used for embedding the teeth groove of described serrated face flexibly connect, be provided with control spring in described active connection place, described card article is provided with its movable control mechanism.
In addition, described window is opened a side in described slideway; Described window is opened in two of described slideway relative sides; The drag link mechanism of the movable control mechanism of its that is provided with on the described card article for being connected with described card article; The movable control mechanism of its that is provided with on the described card article is for being connected with described card article and being made of with the pull bar that is connected with this leverage leverage.
A kind of safety lock valve provided by the utility model is compared with prior art: because the side that is used for fixing and control the pull bar that mechanical mechanism locatees that constitutes in this safety lock valve is provided with serrated face, the card article end of controlling its displacement can be inserted in its teeth groove pull bar is locked, this mechanical structure can be controlled the displacement of pull bar, thereby can effectively control the location of mechanical mechanism, avoid the generation of accident.

Embodiment
The structure and the working principle of the safety lock valve that the utility model is provided below in conjunction with accompanying drawing are described in further detail.
As shown in Figure 1, the structural representation of the unidirectional control safety lock valve that has a window that provides for the utility model.Its structure includes the cartridge type slideway 2 that upper side has window 1, the pull bar 4 that the side is provided with serrated face 3 is through in this slideway and can push-and-pull slides therein, the serrated face of pull bar is in the side of institute's windowing, the side of slideway is provided with supporting frame 5, be used to control the card article 6 and this supporting frame flexible connection of pull bar, be provided with control spring 7 in the joint, one end of card article embeds or withdraws from the control that realizes in the teeth groove 8 of the above-mentioned flank of tooth card article 6 push-and-pull displacements, is fixed in pull bar 11 on the card article 6 for the card article embedding with withdraw from the control mechanism of teeth groove.
The working principle of this safety lock valve is: the cartridge type slideway 2 that safety lock valve is pushed away and an end (or two ends) of pull bar are fixedly connected with the workpiece of being controlled respectively, because the effect of control spring, one end of card article is embedded in the teeth groove 8 on the flank of tooth, makes pull bar be fixed and can not produce displacement; When need realizing displacement, then spur a end that pull bar makes card article and from the flank of tooth, withdraw from and get final product.
For the displacement energy that further makes pull bar accesses effective control, the slideway side of above-mentioned safety lock valve is provided with two supporting frames 5 and two card articles 6 that are used to control pull bar as shown in Figure 2, one termination of these two card articles embeds respectively in the teeth groove 8 on the flank of tooth, thereby more effectively realizes the control to card article 6 push-and-pull displacements.Be illustrated in figure 5 as the control mechanism structural representation of its control safety lock valve, promptly by be in card article middle part and the depression bar 9 that is attached thereto, the leverage 10 of controlling this depression bar constitutes with the pull bar 11 that is connected with this leverage.Its working principle is: the pulling pull bar, and depression bar drives two card articles 6 simultaneously and withdraws from teeth groove, and pull bar can be realized the push-and-pull displacement; Pushing drawing rod, two card articles 6 snap under the effect of control spring 7 in the teeth groove simultaneously, can realize the control to pull bar push-and-pull displacement.
Be illustrated in figure 3 as the structural representation of the safety lock valve of two-sided unidirectional control, its structure is for having window 1 simultaneously on corresponding two sides of cartridge type slideway 2, simultaneously pull bar is provided with two flank of tooth 3, and is through in the slideway and can push-and-pull slides therein; Serrated face is in the side of institute's windowing simultaneously, and the side of slideway is provided with 5, two card articles of two supporting frames 6 and the flexible connection of this supporting frame and is provided with control spring 7, and card article 6 is provided with pull bar 11 as control mechanism.The safety lock valve of this two-sided unidirectional control equally also can realize controlling the purpose that pull bar is realized displacement.
The safety lock valve that has the two-sided two-way control that two windows 1, four supporting frames 5 and four card articles 6 constitute on corresponding two sides of cartridge type slideway 2 simultaneously as shown in Figure 4 equally also can realize controlling the purpose that pull bar is realized displacement.
