Description

Technical Field

[0001] The utility model relates to the technical field of pilot valves, in particular to a pilot valve that is easy to install. Background Art

[0002] At present, the traditional pilot valve is usually installed on the mounting bracket of the accumulator, that is, installed on the tooling. The traditional pilot valve installation usually opens holes on the valve body to connect with the plate on the bracket or the tooling through bolts, but opening holes on the valve body will cause damage to the valve body and affect the appearance, and even affect the operation of the valve body. At the same time, the external tooling and the pilot valve are connected by bolts. Under the high-frequency operation of the pilot valve, part of the vibration force generated by it will be transmitted to the bolts, causing the bolts to loosen or rotate, and then the problem of bolt falling off will occur. At the same time, the plate or tooling on the transmission bracket and the valve body are only connected by bolts, resulting in part of the gravity of the valve body acting on the bolt connection. Under the long-term operation of the valve body, the gravity and vibration force loaded on the bolts are easy to cause the bolts to be damaged or broken. Moreover, only by bolt connection, the valve body has no parts to support it, so that the coaxiality between the valve body and the external hydraulic pipeline and the sealing strength of the connection are affected. Under the long-term operation of the valve body, the coaxiality deviation and sealing failure are prone to occur. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides an easy-to-install pilot valve to solve the problem that when a traditional pilot valve is installed on the side of a tool or equipment, a plurality of holes need to be opened on the valve body to connect bolts, which may cause damage to the valve body or affect the operation of the valve body.

[0004] To achieve the above-mentioned purpose, the utility model provides an easy-to-install guide valve, including a valve body, a base is arranged on one side of the valve body, a connecting piece for connecting to external tooling or equipment is arranged on the base, a bottom plate for supporting the valve body is arranged on the base, a top plate is arranged opposite to the bottom plate and a groove for accommodating the valve body is formed between the bottom plate and the top plate, a connecting structure for improving the connection strength between the bottom plate and the base and improving the supporting strength of the bottom plate to the valve body is arranged between the bottom plate and the base, the top plate is movably arranged on the base along the vertical direction of the bottom plate, and a fixing piece for fixing the top plate is arranged on the base.

[0005] The advantages of adopting the above technical scheme are: when it is necessary to guide the valve body to be installed on external tooling or a bracket, the installer now installs the base on the external tooling or the bracket through a connecting piece. At this time, the base is flush with the outer wall of the external tooling or the bracket. At this time, the bottom plate and the base are perpendicular to each other and the bottom plate is arranged parallel to the external ground. The valve body is then placed on the bottom plate and the top plate is moved so that the top plate moves down and contacts the top of the valve body. At this time, the top plate and the bottom plate are combined to achieve clamping and limiting of the valve body. The operator then fixes the top plate through the fixing piece to fix the valve body as a whole. In the above technology, the bottom plate is used to support and support the valve body, and the connecting structure is used to increase the supporting strength of the bottom plate to the valve body, thereby avoiding coaxiality deviation and sealing failure between the valve body and the external tooling or equipment under long-term operation.

[0006] The utility model is further configured as follows: the connection structure includes two support plates arranged at the bottom of the base plate, the two support plates are arranged opposite to each other and the radial cross-sections of the two support plates are triangular, the top wall of the support plate is connected to the bottom wall of the base plate, and the side wall of the support plate is connected to the outer wall of the base.

[0007] The benefits of adopting the above technical solution are: the connecting structure in the above technology includes two triangular shaped support plates. Because the base is arranged flush with the outer wall of the external tooling or bracket, when the valve body generates vibration force or the weight of the valve body or external high stress acts on the bottom plate, part of the force will be transmitted to the support plate, and then transmitted to the base through the support plate. The base then transmits part of the force to the external tooling or bracket, thereby realizing a high support strength of the bottom plate to the valve body.

[0008] The utility model is further configured as follows: the top plate is composed of two relatively arranged connecting plates, the bottom wall of the connecting plate is an abutting wall for abutting and cooperating with the top wall of the valve body, the side wall of the connecting plate is bent toward the base with a linkage plate, the base is provided with sliding grooves corresponding to the two linkage plate positions, the sliding grooves are opened along the height direction of the bottom plate, a connecting hole is penetrated by the linkage plate, a fixing screw is threadedly connected in the connecting hole, nuts are threadedly connected at both ends of the fixing screw, one of the nuts is abutted and cooperating with the outer wall of the linkage plate, and the other nut is abutted and cooperating with the inner wall of the base, and the fixing screw is the fixing piece.

[0009] The benefits of adopting the above technical solution are: in the above technology, when the top plate needs to be adjusted, the connecting plate can be moved so that the connecting plate abutment wall abuts and cooperates with the valve body top wall. At this time, the linkage plate will move along the height direction of the bottom plate. When the connecting plate needs to be fixed later, the operator screws the fixing screw into the connecting hole and passes one end of the fixing screw through the corresponding slide groove. Then the operator screws the two nuts into the two ends of the fixing screw respectively, one of the nuts abuts and cooperates with the outer wall of the linkage plate, and the other nut abuts and cooperates with the inner wall of the base. In this way, the connecting plate and the base are clamped and limited by the two nuts, thereby realizing the fixation of the linkage plate, thereby realizing the fixation of the connecting plate, and then ensuring that the combination of the connecting plate and the bottom plate can achieve the clamping and limiting of the valve body.

[0010] The utility model is further configured as follows: the base is provided with a plurality of connecting bolts for threaded connection with external tooling or equipment, and the connecting bolts are connecting pieces.

[0011] The above technical solution is beneficial in that the base is connected to external tooling or equipment through connecting bolts.

[0012] The utility model is further provided with: a limiting member is arranged between the nut end of the connecting bolt and the adjacent nut, the limiting member is composed of two limiting plates, and limiting holes are arranged at the starting ends of the two limiting plates, one of the limiting holes is arranged for clamping cooperation with the nut end of the connecting bolt, and the other limiting hole is arranged for clamping cooperation with the nut, and rotating holes are opened at the ends of the two limiting plates, and the two rotating holes are coaxially aligned, and the inner circumferential wall of the rotating hole is circumferentially arranged with first tooth grooves, and a limiting shaft is connected between the two rotating holes, and the outer circumferential wall of the limiting shaft is circumferentially opened with a second tooth groove for meshing with the first tooth groove.

[0013] The advantages of adopting the above technical scheme are: after the connecting bolts are installed, in order to avoid excessive force on the connecting bolts, a limit piece can be installed between the connecting bolts and the adjacent nuts, that is, the limit hole on one of the limit plates is snap-fitted with the nut end of the connecting bolt, and then the limit hole on the other limit plate is snap-fitted with the adjacent nut, so as to achieve the initial fixation of the limit plate. Before the limit plates are matched through the limit holes, the two limit plates need to be swung so that the limit holes of the limit plates can be matched and the two rotating holes can be coaxial. After that, the operator inserts the limit shaft, so The setting of the first tooth groove and the second tooth groove makes it difficult for the limit shaft to rotate in the two rotating holes, thereby realizing the limiting of the two limit plates, and further ensuring that the two limit plates will not rotate and cause failure of the cooperation after respectively cooperating with the connecting bolts and nuts. At the same time, when the weight of the valve body acts on the bottom plate, part of the force will be transmitted to the base, and the base bears the force and transmits part of the force to the connecting bolts. Due to the setting of the limit plate, part of the force is transmitted to the nut, that is, through the limit plate, the connecting bolts and nuts can bear part of the force, thereby improving the service life and supporting strength.

[0014] The utility model is further configured as follows: a buffer pad is arranged between the end surface of the bottom plate and the valve body, and the buffer pad is made of elastic material.

[0015] The benefit of adopting the above technical solution is that the buffer pad in the above technology is used to support the valve body and play a buffering role when the vibration force generated by the valve body during operation is transmitted to the bottom plate.
