Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the high-pressure stop valve comprises a valve body 1 and a valve cover 2 arranged on the valve body 1, wherein a valve clack 3 is arranged in the valve body 1, and a valve rod 4 is vertically arranged at the top of the valve clack 3.

As shown in fig. 1 and 2, the valve cap 2 is provided with a sliding hole 21 for the valve rod 4 to penetrate through, the valve rod 4 is vertically slidably connected to the sliding hole 21, and the outer wall of the valve rod abuts against the inner wall of the sliding hole 21.

When closing above-mentioned stop valve, drive valve rod 4 downstream, valve rod 4 drives valve clack 3 synchronous downstream this moment, cuts off the runner in the valve body 1 until valve clack 3 to realize closing of stop valve.

When the stop valve is opened, the valve rod 4 is driven to move upwards, and the valve rod 4 drives the valve clack 3 to move upwards synchronously until the flow channel in the valve body 1 is opened, so that the stop valve is opened.

As shown in fig. 1 and 2, a supporting seat 5 is arranged on an outer wall of one side of the valve cap 2, a supporting rod 51 is vertically arranged on the supporting seat 5, and a driving rod 52 is hinged on the supporting rod 51. A handle 6 extends from one end of the driving rod 52, which faces away from the supporting rod 51, and a groove 61 for fingers to insert is formed in the outer wall of the lower end of the handle 6.

As shown in fig. 1 and 2, a locking seat 7 is disposed on a side of the bonnet 2 away from the support seat 5, a locking hole 71 penetrates through the locking seat 7, a locking rod 72 is vertically and slidably connected in the locking hole 71, and a fixing portion 8 for fixing the locking rod 72 is further disposed on the locking seat 7.

As shown in fig. 1 and 2, a sliding tube 53 is slidably connected to the middle of the driving rod 52, and a locking tube 54 is slidably connected to the outer wall of one end of the driving rod facing away from the supporting rod 51. The upper end of the valve rod 4 is hinged to the outer wall of the lower end of the sliding tube 53, and the upper end of the locking rod 72 is hinged to the outer wall of the lower end of the locking tube 54.

It should be noted that: the hinge point of the driving lever 52 and the supporting lever 51 serves as a fixed point, and since the sliding tube 53 and the locking tube 54 are slidably connected to the driving lever 52, the hinge point of the valve stem 4 and the sliding tube 53 and the hinge point of the locking lever 72 and the locking tube 54 are movable points. When the stop valve is closed, the handle 6 is pressed to move downwards, the handle 6 drives the driving rod 52 to rotate downwards along the hinged part, the driving rod 52 slides along the inner walls of the sliding pipe 53 and the locking pipe 54 at the moment, the valve rod 4 and the locking rod 72 are driven to move downwards, and the valve rod 4 drives the valve clack 3 to move downwards synchronously at the moment. After the valve clack 3 cuts off the flow channel in the valve body 1, the locking rod 72 is fixed by the fixing part 8, and the valve rod 4 and the valve clack 3 can be fixed, so that the stop valve is closed.

When the stop valve is opened, the fixing part 8 is firstly released, then the driving rod 52 is pulled to move upwards, at the moment, the driving rod 52 drives the valve rod 4 and the locking rod 72 to move upwards, and simultaneously, the valve rod 4 drives the valve clack 3 to move upwards. The locking rod 72 is fixed again by the fixing part 8 until the flow passage in the valve body 1 is opened, and the stop valve is maintained in the open state.

As shown in fig. 3, a baffle plate 73 is disposed on a lower end surface of the locking rod 72, an extension spring 74 is sleeved on an outer wall of the lower end of the locking rod 72, the extension spring 74 is located between the locking seat 7 and the baffle plate 73, and two ends of the extension spring 74 are respectively fixed to the lower end surface of the locking seat 7 and an upper end surface of the baffle plate 73.

When the shut valve is closed, the locking lever 72 brings the flap 73 in synchronism with the downward movement, and the flap 73 pulls the extension spring 74 to extend. When the shut valve is opened and the fixing portion 8 is released, the extension spring 74 retracts and drives the flap 73 and the locking lever 72 to move upward quickly and automatically, thereby achieving quick opening of the shut valve. The above-mentioned extension spring must not exceed its elastic limit (i.e. maximum extension) when the stop valve closes the flow passage, so that the extension spring has long-term elastic performance.

As shown in fig. 3, the fixing portion 8 includes a fixing rod 81, the outer wall of the locking seat 7 is provided with a fixing hole 75 communicating with the locking hole 71, the fixing rod 81 is slidably connected to the fixing hole 75, and one end of the fixing rod 81 located outside the fixing hole 75 is provided with a pull ring 82.

As shown in fig. 3, a cavity 76 is formed on an inner wall of the fixing hole 75, and a reset plate 83 located inside the cavity 76 is fixedly connected to an outer wall of the fixing rod 81. The outer wall of the fixing rod 81 is sleeved with a return spring 84, and the return spring 84 is located between the return plate 83 and one side wall of the cavity 76.

As shown in fig. 3, the outer wall of the locking rod 72 is further provided with a pair of fixing grooves 77 for the fixing rod 81 to be inserted, the pair of fixing grooves 77 is distributed at the lower end of the locking rod 72, and the fixing rod 81 and the bottom wall of the fixing groove 77 are both provided with magnets 9 that attract each other.

When the shut valve is closed, the pull ring 82 is pulled to drive the fixing lever 81 to move outwards, and at this time, the fixing lever 81 drives the reset plate 83 to move synchronously, and the reset spring 84 is pressed to compress, and meanwhile, the fixing lever 81 gradually disengages from the fixing groove 77 at the lower end of the locking lever 72. The lock lever 72 is released until the fixing lever 81 completely disengages from the fixing groove 77.

When the shut valve is completely closed, the fixing rod 81 is aligned with the fixing groove 77 at the upper end of the locking rod 72, at this time, the fixing rod 81 is released, the reset spring 84 springs open and pushes the reset plate 83 to move reversely, and simultaneously, the reset plate 83 drives the fixing rod 81 to be inserted into the fixing groove 77 at the upper end of the locking rod 72, so that the locking of the locking rod 72 is realized.

When the shut valve is opened, the fixing lever 81 is moved outward by pulling the pull ring 82, and the fixing lever 81 is gradually separated from the fixing groove 77 of the outer wall of the upper end of the locking lever 72. And after the fixing rod 81 is completely separated from the fixing groove 77, the locking rod 72 automatically moves upwards to open the stop valve.

And when the shut valve is completely opened, the fixing rod 81 is aligned with the fixing groove 77 at the lower end of the locking rod 72, at this time, the fixing rod 81 is released, the reset spring 84 springs open and pushes the reset plate 83 to move reversely, and simultaneously, the reset plate 83 drives the fixing rod 81 to be inserted into the fixing groove 77 at the lower end of the locking rod 72, so that the locking of the locking rod 72 is realized again.
