Description
Technical field
The utility model relates to valve field, particularly relates to a kind of stop valve.
Background technique
At present, valve common on market is straight-through or threeway, they generally only have a gas-entered passageway and an outlet passageway threeway just to switch outlet passageway, when sometimes gas circuit needing to use multiple outlet passageway, just the gas path pipe on rear side of air outlet must increase offtake, which adds the complexity of gas circuit.Further, existing valve can manage it for sealing effect during water route, during for gas circuit, is particularly useful for low pressure gas circuit, as the gas circuit under 2.5KPa air pressure, often occurs micro-leakage, affect test result.
Model utility content
The utility model only has a gas-entered passageway and an outlet passageway and the undesirable problem of low pressure seal effect in order to the valve solved in the market, and proposing a kind ofly has multiple outlet passageway and the effective stop valve of low pressure seal.
To achieve these goals, the utility model by the following technical solutions: a kind of stop valve, the sealing block that the valve gap comprise valve body, fixing with valve body, handwheel and being controlled by handwheel can be moved up and down along valve gap is sphere bottom described sealing block; Described valve body is regular prism, inside is the valve pocket that open upper end is connected with valve gap, valve pocket bottom surface is provided with the vent running through valve body, and corresponding with sealing block position and be provided with the cambered surface of mating with sphere bottom sealing block inside vent, outside is provided with tracheae connecting body; Valve body side is run through valve pocket and is provided with at least one attachment hole, is provided with internal thread in attachment hole.
As preferably, described valve body side is run through valve pocket and is provided with two attachment holes.
As preferably, tracheae connecting body is divided into joint, input termination and nut, and described joint connects valve body and input termination, and joint is provided with the outside thread mated with nut, and described input end head portion is taper.
As preferably, described nut side is provided with the ear structure is convenient to hand and twisted.
Therefore, the utility model has following beneficial effect: (1) is provided with multiple outlet passageway, is convenient to control multichannel gas circuit simultaneously; (2) sealed by crush seal circle between sealing block and valve body, low pressure seal is effective; (3) portion of screwing is provided with ear structure, both twists by spanner, also can twist by hand.
