Description

Hand-hydraulic cutter type Parallel Slide Valves

Technical field

The utility model relates to a kind of hand-hydraulic cutter type Parallel Slide Valves, is used for the conveying of slurries such as coal slurry, mortar.

Background technique

Parallel Slide Valves is used for slurries delivery lines such as coal slurry, mortar, is generally the paddle type valve, and traditional paddle type valve adopts operated by handwheel, mechanical transmission, and the flashboard rising or falling speed is slow, the operation effort.

Summary of the invention

The purpose of this utility model provides a kind of hand-hydraulic cutter type Parallel Slide Valves, utilizes hydraulic transmission principle, makes the flashboard fast lifting, rapid operation.

The utility model hand-hydraulic cutter type Parallel Slide Valves contains valve seat, valve rod, and cutter type flashboard also comprises hydraulic jack, oil tank, hand oil pump and selector valve, and oil tank and hydraulic jack are provided with the cover plate that is connected as a single entity, and cover plate is provided with the spill port of logical oil tank; The piston of hydraulic jack is connected with valve rod, and hydraulic jack is provided with upper and lower two oil circuits; The fuel sucking pipe of hand oil pump stretches in the fuel tank, the upper and lower oil circuit of the oil outlet tube of hand oil pump and hydraulic jack, the spill port of oil tank are with linking to each other with the selector valve corresponding points, one in oil pump outlet line road and upper and lower two oil circuits of hydraulic jack communicates, spill port communicates with another oil circuit, by handle control commutation, the fuel-displaced pipeline of said hand oil pump and the upper and lower oil circuit of hydraulic jack all have one section horizontal hole that is opened in the cover plate.The bottom of hydraulic jack is provided with sealing axle sleeve.

The utility model is by rotating the selector valve handle, can make the oil outlet of hand oil pump select a road in the upper and lower oil circuit with hydraulic jack to communicate, and another oil circuit then communicates with spill port.When oil circuit and oil pump were connected instantly, hand oil pump was sent into pressure oil to the below of hydraulic jack, and piston is pushed and moves upward, and the oil with the piston top feeds spill port by last oil circuit simultaneously, flows back to oil tank.Drive flashboard in the above-mentioned piston uphill process and move upward, Parallel Slide Valves promptly is unlocked.When needing to close valve, the selector valve handle is pulled to opposite side, the outer pipe of hand oil pump switched to last oil circuit communicate, same oil circuit at present promptly is switched with spill port and communicates, rotate the hand oil pump handle this moment again, hydraulic oil promptly enters from the oil cylinder upper end, and piston is pushed and moves downward, and the oil of oil cylinder below flows back to oil tank by following oil circuit simultaneously.In this process, flashboard is moved down by drive, and Parallel Slide Valves is closed.

In sum, this Parallel Slide Valves adopts fluid drive mechanism to drive valve rod, only needs to rotate the handle of selector valve and hand oil pump, can easily realize out valve or close valve that speed is fast, and laborsaving; Utilize the interior horizontal hole of cover plate as oil circuit, make this valve arrangement compacter.

Embodiment

As shown in Figure 1 and Figure 2, valve seat 1, valve rod 3,

cutter type flashboard

2,16 are arranged is the slurries port to these slurries; Valve rod 2 upper ends are connected with the piston 5 of hydraulic jack 4, and the bottom of hydraulic jack 4 is provided with sealing axle sleeve 10, and cover plate 6 is the upper cover plate of oil tank 9 and oil cylinder 4 altogether, and hand oil pump 8 and selector valve 7 are fixed on the end face of cover plate 6.Oil pump 8 is provided with handle 8-1, and selector valve 7 is provided with handle 7-1.Oil cylinder is connected to down oil circuit 11, and the upper end of this oil circuit 11 is one section horizontal hole A (seeing Fig. 4,5) that are included in the cover plate 6, and the last oil circuit 12 of oil cylinder is the horizontal hole B (seeing Fig. 4,5) in the cover plate 6.The structure and the working principle of hand oil pump 8 are seen Fig. 3, oil pump piston 8-3 is equipped with one-way valve 8-2, when spurring handle 8-1 back and forth, piston 8-3 promptly moves around, enter the oil cylinder 8-7 of pump by the oil in the fuel sucking pipe 8-5 suction fuel tank 9, through oil sucting valve 8-6, right-hand interior oil of cylinder of piston is pressurized simultaneously, enter cover plate duct P (seeing Fig. 4,5) by fuel-displaced by oil outlet tube 8-4, and at bore end select by selector valve 7 to communicate with the duct A of the duct B of oil circuit 12 or time oil circuit 11 on the hydraulic jack (seeing Fig. 4).The structure of cover plate 6 is seen Fig. 4, it is made up of fuel tank cap 6-1 and oil cylinder 6-2 two-part, the two is an integral body, among the figure 13 and 13 ' be the bolt hole of fixed manual oil pump 8, the fuel sucking pipe 8-5 of oil pump 8 stretches into fuel tank 9 (referring to Fig. 2,3) by the hole O of cover plate, among Fig. 4, the horizontal hole that is opened in the cover plate is represented by dotted lines, and it is starting point from the edge of cover plate that each duct adds man-hour, horizontal drilling in plate, subsequently the starting point aperture is blocked, 14 are obstruction among the figure.Oil in the P of duct flows to as arrow, and promptly the oil outlet tube 8-4 by oil pump flows to the selector valve interface, and its effective hole section is aperture 8-4 to P.Effective hole section of duct A is the following oil circuit 11 of aperture A to hydraulic jack, and effective hole section of duct B is the last oil circuit 12 of aperture B to the liquid oil cylinder, and hole T is vertical hole, and its lower end communicates with oil tank 9.P, A, four apertures of B, T with and the corresponding contact of the selector valve 7 of cover plate top connect, by pulling selector valve handle 7-1, can select to make P to communicate as required with A or B, T is communicated with B or A.When Fig. 5 state, P communicates with A, and T communicates with B, at this moment, the pressure oil of oil pump output flows into duct P from outlet valve 8-4, feeds duct A from selector valve path 7-2, and 11 lower ends from Fig. 1 oil cylinder 4 enter in the cylinder by the road, piston 5 is moved up, and drive flashboard 2 risings, Parallel Slide Valves is opened; Meanwhile, the oil of piston 5 tops enters duct B by last oil circuit 12, and 7-3 goes into spill port T by the selector valve inner gateway, flows back in the oil tank 9.In the time of need closing this slurry pump, only need oppositely pulling selector valve handle 7-1, its valve inner gateway 7-2 promptly transfers P-B to from P-A, valve inner gateway 7-3 transfers T-A to from T-B, and hydraulic circuit promptly changes into: go up oil circuit 12 oil-feeds, following oil circuit 11 oil returns, piston drives gate 2 and descends, and this Parallel Slide Valves is closed.
