Abstract
The utility model discloses the pressure regulation cap device on a kind of pressure regulator valve, comprise pressure regulation cap and be set in the pressure adjusting roller outside pressure regulation cap, pressure regulation cap has the outward turning transfer part of outer-hexagonal shape, pressure adjusting roller inwall has and hexagonal interior rotary part in the cooperation of outward turning transfer part, the upper-end surface of pressure regulation cap has interior threaded hole, the joint leant with the upper-end surface of pressure regulation cap is provided with in pressure adjusting roller, joint is connected in pressure adjusting roller inwall, described joint has the screw hole corresponding with described interior threaded hole, joint is removably fixed on the upper-end surface of pressure regulation cap by screw.Because pressure regulation cap is connected with the inward turning portion of earning by hexagonal outward turning transfer part with pressure adjusting roller, pressure adjusting roller would not rotate relative to pressure regulation cap in operation, again because pressure adjusting roller is fixed on pressure regulation cap by screw further, pressure adjusting roller is not easy loosen and depart from pressure regulation cap, improves the stability that pressure regulation cap is connected with pressure adjusting roller.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to the pressure regulation cap device on a kind of pressure regulator valve.
Background technique
High pressure cleaning pump having pressure regulator valve usually for regulating high pressure cleaning pump discharge pressure, pressure regulator valve being provided with pressure regulation cap, operator regulate pressure regulator valve by rotating pressure regulation cap.
Existing pressure regulation cap is provided with pressure adjusting roller, and pressure adjusting roller is set on pressure regulation cap, and operator directly contact pressure adjusting roller, rotates pressure regulation cap by rotating pressure adjusting roller.What have between pressure adjusting roller and pressure regulation cap is connected by drive fit, and what have is threaded connection.Time between pressure adjusting roller and pressure regulation cap by tight fit connection, the time is once easily loosening for a long time; When being threaded connection between pressure adjusting roller and pressure regulation cap, when pressure adjusting roller is rotated counterclockwise, easily pressure regulation cap occurs to loosen relatively, impels pressure adjusting roller to revolve de-pressure regulation cap.
Summary of the invention
The utility model proposes the pressure regulation cap device on a kind of pressure regulator valve for prior art Problems existing, object is the stability that raising pressure regulation cap is connected with pressure adjusting roller.
The utility model is achieved in that
Pressure regulation cap device on a kind of pressure regulator valve, comprise pressure regulation cap and be set in the pressure adjusting roller outside pressure regulation cap, it is characterized in that, described pressure regulation cap has the outward turning transfer part of outer-hexagonal shape, described pressure adjusting roller inwall has and hexagonal interior rotary part in the cooperation of described outward turning transfer part, the upper-end surface of described pressure regulation cap has interior threaded hole, the joint leant with the upper-end surface of described pressure regulation cap is provided with in described pressure adjusting roller, described joint is connected in described pressure adjusting roller inwall, described joint have the screw hole corresponding with described interior threaded hole, described joint is removably fixed on the upper-end surface of described pressure regulation cap by screw.
In pressure regulation cap device on above-mentioned a kind of pressure regulator valve, the upper end of described pressure adjusting roller has the mount inlet inserted for screw-driver, described mount inlet is provided with wheel cap.
In pressure regulation cap device on above-mentioned a kind of pressure regulator valve, described cap of taking turns is connected on described pressure adjusting roller.
In pressure regulation cap device on above-mentioned a kind of pressure regulator valve, described joint is in banded, and the two ends of described joint are fixed on the inwall of described pressure adjusting roller.
In pressure regulation cap device on above-mentioned a kind of pressure regulator valve, described joint is circular, and the week of described joint is along being fixed on the inwall of described pressure adjusting roller.
In pressure regulation cap device on above-mentioned a kind of pressure regulator valve, described inner rotary portion is positioned at the underpart of described pressure regulation cap, and the diameter of the upper end portion of described pressure regulation cap is equal to or less than the diameter of described outward turning transfer part incircle.
Pressure regulation cap device on a kind of pressure regulator valve provided by the utility model, because pressure regulation cap is connected with the inward turning portion of earning by hexagonal outward turning transfer part with pressure adjusting roller, pressure adjusting roller would not rotate relative to pressure regulation cap in operation, again because pressure adjusting roller is fixed on pressure regulation cap by screw further, pressure adjusting roller is not easy loosen and depart from pressure regulation cap, improves the stability that pressure regulation cap is connected with pressure adjusting roller.
Accompanying drawing explanation
Fig. 1 is the explosive view of the utility model pressure regulation cap device.
Embodiment
Below just accompanying drawing in conjunction with the embodiments, is described in further detail embodiment of the present utility model, is easier to understand, grasp to make technical solutions of the utility model.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The present embodiment provides the cap device of the pressure regulation on a kind of pressure regulator valve, as shown in Figure 1, comprises pressure regulation cap 100 and pressure adjusting roller 200.Wherein, pressure adjusting roller 200 is set in outside pressure regulation cap 100.
Specifically, what be first pressure regulation cap 100 with in pressure adjusting roller 200 circumference is relative fixing.Described pressure regulation cap 100 has the outward turning transfer part 110 of outer-hexagonal shape, described pressure adjusting roller 200 inwall has and hexagonal interior rotary part in the cooperation of described outward turning transfer part 110.That is, positive six prisms in outward turning transfer part 110, the global shape of pressure regulation cap 100 can be positive six prisms, preferably, described outward turning transfer part 110 is positioned at the underpart of described pressure regulation cap 100, and the diameter of the upper end portion of described pressure regulation cap 100 is equal to or less than described outward turning transfer part 110 inscribe diameter of a circle.Pressure adjusting roller 200 in tubbiness, the diameter of pressure adjusting roller 200 by under upwards reduce gradually, the upper end portion that transverse dimension is less is conducive to pressure adjusting roller 200 and is inserted in pressure regulation cap 100.
Moreover be pressure regulation cap 100 and pressure adjusting roller 200 axially relative fixing.The upper-end surface of described pressure regulation cap 100 has interior threaded hole 120, the joint 220 leant with the upper-end surface of described pressure regulation cap 100 is provided with in described pressure adjusting roller 200, described joint 220 is connected in described pressure adjusting roller 200 inwall, described joint 220 has the screw hole with described interior threaded hole 120 correspondence, described joint 220 is removably fixed on the upper-end surface of described pressure regulation cap 100 by screw 400, has pad 500 between screw 400 and joint 220.Wherein, joint 220 is positioned at the top of rotary part, and joint 220 can be in banded, also can be rounded.When joint 220 is in time banded, the two ends of joint 220 are fixed on the inwall of pressure adjusting roller 200; When joint 220 is circular, the week of joint 220 is along being fixed on the inwall of described pressure adjusting roller 200.
