Description
Technical field
The utility model relates to a kind of mechanical type Fill valve that is applied to diaphragm pump.
Background technique
Mechanical type Fill valve is often applied to the repairing of diaphragm pump, in traditional structure of mechanical type Fill valve that is applied to diaphragm pump, as shown in Figure 3, because spool 4 and bearing 12 are at right angle settings and are linked together, in the time of repairing, barrier film guide rod 1 need to be by bearing 12 jack-up obliquely, spool 4 could be opened, therefore can cause spool 4 to be subject to larger radial force, and then cause spool 4 and lower valve body 3 rapid wears, thereby reduce its reliability and working life; In addition, in repairing process, because barrier film guide rod 1 is a kind of cantilever beam structure, barrier film guide rod 1 can bear certain radial load and produce deformation, makes barrier film fall bar 1 and increases with the gap of spool 4, and then cause repairing error excessive, can not promptly and accurately supply the hydraulic oil of hydraulic chamber, particularly, in the situation that hydraulic chamber's oil starvation is few, can not truly reflect definite oil mass state, also just not reach repairing effect; This valve requires very high to Installation and Debugging besides, need the strict gap of controlling bearing 12 and barrier film guide rod 1 in a suitable scope, otherwise can cause repairing too early or postpone to mend oil condition, and this valve processing is comparatively complicated, sealing station is many, therefore also has certain hidden danger.Obviously, a kind of suitable mechanical type Fill valve of diaphragm pump exigence solves the problems referred to above.
Summary of the invention
The purpose of this utility model is to provide a kind of mechanical type Fill valve that is applied to diaphragm pump, to solve the large and large problem of Installation and Debugging difficulty of the reliability deficiency that exists in prior art, repairing error.
The purpose of this utility model can reach by following technical measures, , this mechanical type Fill valve that is applied to diaphragm pump, comprise valve body, spool, repairing mouth, oil guiding hole and barrier film guide rod, described valve body comprises upper valve body and lower valve body, repairing mouth is arranged on upper valve body top, the junction of upper valve body and lower valve body is circumferentially with seal groove, seal groove inner side is provided with transition slot, oil guiding hole is vertically arranged on upper valve body and lower valve inner, one end of this oil guiding hole is communicated with repairing mouth, the other end is through transition slot, be combined with spool sidewall sealing paste, spool is horizontally installed in lower valve body, and this spool head is arranged with return spring, described barrier film guide rod is perpendicular to lower valve body, and this barrier film guide rod is coaxial with return spring.
Further, in described seal groove, be provided with seal ring.
Further, described seal ring is O RunddichtringO.
Further, described transition slot is cylindrical transition slot.
Further, the other end of described oil guiding hole and spool sidewall vertical seal fit together.
Compare traditional mechanical type Fill valve that is applied to diaphragm pump, the advantage that the utility model is applied to the mechanical type Fill valve of diaphragm pump is:
1, be vertically arranged on upper valve body and lower valve inner because the utility model is applied to oil guiding hole described in the mechanical type Fill valve of diaphragm pump, oil guiding hole needn't bend to arrange and produce multiple seal points, has reduced seal leakage point, has promoted the reliability of sealing configuration.
2, because being applied to spool described in the mechanical type Fill valve of diaphragm pump, the utility model is horizontally installed in lower valve body, and this spool head is arranged with return spring, barrier film guide rod is perpendicular to lower valve body, and this barrier film guide rod is coaxial with return spring, in repairing process, barrier film guide rod backs down spool with coaxial contact of return spring, spool and barrier film guide rod are only subject to axial force and are not subject to other active forces, the reliability of mechanical type Fill valve and the working life of spool are promoted therefore not only avoided spool rapid wear, also avoided barrier film guide rod to produce deformation and spool gap is with it changed, reduce repairing error.
3, due to the utility model, to be applied to described in the mechanical type Fill valve of diaphragm pump barrier film guide rod coaxial with return spring perpendicular to lower valve body and this barrier film guide rod, make the gap of spool and barrier film guide rod more easy to control a suitable scope, reduced the difficulty of Installation and Debugging.
Accompanying drawing explanation
Fig. 1 is the structure sectional view that the utility model is applied to the mechanical type Fill valve of diaphragm pump;
Fig. 2 is the A portion enlarged diagram of Fig. 1;
Fig. 3 is the structure sectional view of the existing mechanical type Fill valve that is applied to diaphragm pump;
In Fig. 1, Fig. 2 and Fig. 3,1 is barrier film guide rod, and 2 is return spring, and 3 is lower valve body, and 4 is spool, and 5 is transition slot, and 6 is seal groove, and 7 is seal ring, and 8 is upper valve body, and 9 is oil guiding hole, and 10 is repairing mouth, and 11 is valve body, and 12 is bearing.
The mechanical type Fill valve that the utility model is applied to diaphragm pump below in conjunction with the drawings and specific embodiments is further described.
Embodiment
As depicted in figs. 1 and 2, a kind of mechanical type Fill valve that is applied to diaphragm pump, comprise valve body 11, spool 4, repairing mouth 10, oil guiding hole 9 and barrier film guide rod 1, described valve body comprises upper valve body 8 and lower valve body 3, repairing mouth 10 is arranged on upper valve body 8 tops, upper valve body 8 is circumferentially with seal groove 6 with the junction of lower valve body 3, seal groove 6 inner sides are provided with transition slot 5, oil guiding hole 9 is vertically arranged on upper valve body 8 and lower valve body 3 inside, one end of this oil guiding hole 9 is communicated with repairing mouth 10, the other end is through transition slot 5, be combined with spool 4 sidewall sealing pastes, spool 4 is horizontally installed in lower valve body 3, and these spool 4 heads are arranged with return spring 2, described barrier film guide rod 1 is perpendicular to lower valve body 3, and this barrier film guide rod 1 is coaxial with return spring 2.
