Description
Technical field
The utility model relates to a kind of foot valve, particularly a kind of three-position five-way foot valve that adopts the mode of riding to realize airflow direction is switched use.
Background technique
Existing tradition foot valve commonly used mostly is two-position five-way valve, only plays many-sided requirement that on-off action can't satisfy the user.
Patent No. CN200920192039 " three-position five-way pneumatic foot switch ", though also disclose a kind of foot switch easy to use, its structure is compact not enough, so its volume is large, heavy weight, cost of production is high.
The model utility content
Technical problem to be solved in the utility model is: a kind of three-position five-way foot valve is provided, and compact structure, volume are little, good airproof performance, noise are little, simple to operation, can satisfy the many-sided different demands of user, and using scope is wide.
The technical scheme in the invention for solving the above technical problem is: the three-position five-way foot valve, comprise the bonnet that pedal is installed, bonnet is fixed on advancing, relief opening P, R1, R2, gas delivery port A, on the ear end face of B valve body, the valve rod that is connected with seal ring is installed in the valve body that is connected with valve pocket, groove with through hole is arranged on the described valve pocket, also be connected with seal ring, one end of valve rod passes through clevis, connecting pin on carrier bar and the pedal connects into integral body, also be connected with positioning shaft on the described valve rod the other end, in being connected with on the positioning shaft, outer position limit cycle, in, cover has spring on the positioning shaft between outer position limit cycle, and the front-end face of described valve body also is fixed with setting sleeve.
Compared with prior art, the utility model has the advantage of: this foot valve compact structure, volume is little, only on the basis of original two-position five-way foot valve, increase valve rod, the length of valve body, i.e. spreading stationary positioned cover on valve body, increase positioning shaft at valve rod, and the two ends that make valve rod utilize the interior steel ball difference tensioner of curve bath at positioning shaft, connect into integral body in the bell-mouthed blind hole of clevis one end band, and positioning shaft, clevis can rotate around steel ball, the effect that can extremely not have universal joint, its resistance is little, noise is low, the while positioning shaft, clevis and valve rod adopt different materials making wear resistance good, increased the working life of foot valve, operation, easy to use, can satisfy the many-sided different requirement of user.Because inside and outside position limit cycle being arranged with exterior edge face and the location of the ladder surface on the setting sleeve of valve body, guarantee inlet and outlet mouth, gas delivery port, remain constant with the valve pocket duct position, guarantee the stability of work and accurate safety reliability and the sealing of use.A mobile distance can be made into two kinds of different valve rods only to need to make the position of a seal ring slightly change backward at valve rod, satisfies envelope formula or center-leakage type state requirements of one's work in the work, and using scope is wide.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Pedal 1 upper surface has the anti-skidding striped that increases friction, and there are horizontal mounting hole and two connecting pin 1-1 in the lower end, and pedal is hinged on two dunnages of bonnet 4 with the connecting pin 1-1 on it.
16 4 jiaos of setting sleeves have mounting hole, and there is step-shaped blind hole the centre.
Before the valve body 5, gas delivery port A is arranged respectively on the rear sidewall, B and relief opening R1, R2, suction port P, and communicate with valve pocket respectively, before, on four jiaos of the ear end faces installation screw is arranged, on, lower surface has mounting hole, drive fit has columnar valve pocket 6 in the intermediate throughholes, valve pocket 6 outer surfaces axially have uniform, the five road ring grooves at interval and six seal grooves, uniform identical small through hole is arranged on the per pass ring groove periphery, A on the corresponding valve body of described small through hole difference, B, R1, R2, the P hole, the corresponding large large O RunddichtringO 8 of diameter of installing of seal groove makes 5 sealings of valve pocket 6 and valve body.
The circular arc notch 7-3,7 '-3 that cooperates with steel ball 10 is arranged in the middle of valve rod 7, the 7 ' both ends of the surface.
Positioning shaft 11 is stepped stem, inside and outside position limit cycle 12,14 is installed on it, cover has spring 13 on inside and outside position limit cycle 12,14 the positioning shaft, in the groove that outer position limit cycle 14 embeds collar 15 is installed also, make the part of installing on the positioning shaft can not carry out spacing by axial float, there is blind hole the centre of the positioning shaft the other end, and blind orifice end 11-1 is tubaeform, as shown in Figure 9.
Will with the valve rod 7,7 of steel ball 10 ' two ends respectively in the tight blind hole of inserting positioning shaft 11, clevis 3 one ends, make steel ball 10 tensioner in blind hole, with valve rod 7,7 ' connect into integral body with positioning shaft 11, clevis 3 respectively.
